The Application of Stepping Motor in Solar Slew Tracking System

There are two main slewing drive for solar tracking system to track the sun: photoelectric tracking and tracking according to the motion track of the apparent sun. The advantage of tracking according to the motion track of the apparent sun is that it can track in real time all the time. Generally, it is driven by stepper motor with two axes, and realizes all-weather tracking of the sun by controlling the tracking mechanism with two degrees of freedom of horizontal and pitching.

The solar tracker slew drive according to the motion track of the apparent sun is a dual axis automatic track system based on single chip microcomputer. The system adopts horizontal orientation stepper motor and pitch direction stepper motor to track the azimuth Angle and altitude Angle of the sun so that the position of the sun can be accurately tracked in real time. Therefore, the accuracy of the stepping motor and the mechanical structure of the tracking table are one of the factors that affect the tracking accuracy of solar energy. Aiming at the influence of this factor, manual correction operation is usually adopted to reduce the error. The method is to control the horizontal pitch azimuth stepper motor so that two axes drive the plane mirror reflector. At the same time, the shadow reflected by the plane mirror is continuously observed. When the shadow center just gathers at the designated point, it is the best to record the steps taken by the stepper motor from the origin to the point. According to the difference between the number of actual running steps and the number of theoretical running steps, the difference of Angle can be calculated, which is the correction value of altitude Angle and azimuth Angle. Record data at different times of the day. The tracking accuracy can be improved by using the correction coefficient to correct the theoretical value stored in the control program. We have slewing drive solar tracker ,welcome to consult.

Slew drive can also be called slew drive gearbox. Most of our slewing ring drive is kind of worm gear reducer. And the slew ring bearing is a gear drive part.

The slewing drive is a full-cycle rotary reduction transmission mechanism integrated with a driving power source. As a professional slew bearing manufacturer in india, Fuyong Intelligent produces high-quality slewing drive products! Any inquiry is welcome!

How long we should be replacing a belt on a ca

1.When we check the automotive belts, if we find defects in the core fracture and the groove fracture, then we need to replace it immediately and estimate the car fan belt replacement cost .

2.When the cover of the belt is separated from the pull rope, or when the pull rope is loose, we have to change the belt.

3.When the belt is placed on the pulley, there should be a gap between the inner diameter of the belt and the bottom of the pulley slot, and if there is no gap, we must also replace the belt

Car belt of the motor is made of rubber, and the belt wear rate is high. Because most belts on the car use the of material rubber, so the auto belt inevitably wears away and ages during long periods of high temperature work. So generally speaking, the car belt replacement time is regulated by car manufacturers,and there is some introduction in the vehicle maintenance manual .

According to the general car maintenance standards, after running about 60,000 to 80,000 kilometers the belt should be replaced, and some belts can be replaved after driving 80,000 to 100,000 kilometers.

How to replace a new belt for car

1. loose the motor fixing screw and the belt tightness adjusting screw.

2. push the generator against the engine to make the distance between the pulley the shortest, and then straighten the belt sleeve.

3. adjust the tightness of the belt to fit, and tighten the engine fixing screw and adjusting screw.

Car generator belt installation needs professional tools and technical advice from professionals to operate. Self-installation by car owners may cause damage.

How to maintain the drive motor belt

1.After driving a certain distance, you should properly adjust the tightness of the generator belt. Fix the calibration screws as required to ensure that the screws on the foot frame of the generator maintain a certain tightness.

2.You should pay attention to the degree of bearing wear. If insufficient lubrication is found, you may add a few drops of oil from the mouth of the oil cup. Pay attention not to let the oil enter the rectifier, otherwise it will affect the effect of power transmission.

3.Rectifier scale can be polished with fine sand cloth.

4.Uneven brush contact surface can be leveled with fine sand cloth. Spring is not elastic enough, brush wear too much, both situations should replace new parts. The brush is too short and without breakage. The gasket can be plugged into the support to make it close to the rectifier.

With the development automation technology, automatic welding technology is more advanced. Automatic welding machine plays an important role in the application of various industries, and its application is expanding rapidly. In the modern industrial production, the mechanization and automation of the welding production process are the inevitable trends of the manufacturing industry. The automatic welding machine we provided, with more efficient, high welding precision and fast welding speed, can be widely used in many fields.

In the past 20 years, with the development of digital, automation, computer, mechanical design technology and the importance of welding quality, automatic welding has developed into an advanced manufacturing technology, and role automatic welding equipment plays in various industrial applications is more and more important, and the scope of application is expanding rapidly. In modern industrial production, the mechanization and automation of the welding production process is an inevitable trend in the modernization of the welding mechanism manufacturing industry.

According to the degree of automation, automated welding equipment can be divided into the following three categories:

1. Rigid automated welding equipment Rigid automatic welding equipment can also be called primary automatic welding equipment, most of which are designed according to the principle of open loop control. Although the entire welding process is automatically completed by the welding equipment, the feedback of the welding parameters during the welding process cannot be closed-loop feedback system, and the possible deviations cannot be randomly corrected.

2. Self-adaptive control automatic welding equipment The adaptively controlled welding equipment is a highly automated welding equipment, which is equipped with sensors and electronic detection lines, it can automatically guide and tracks the weld trajectory, and implements closed-loop feedback control of the main welding parameters. The entire welding process will be completed automatically according to preset procedures and process parameters.

Intelligent automatic welding equipment

It utilizes a variety of advanced sensing components such as vision sensors, tactile sensors, auditory sensors and laser scanners etc., and it makes uses of computer software systems, databases and expert systems with functions such as identification, judgment, real-time detection, calculation, automatic programming, welding parameters storage and the ability to automatically generate weld log files.

The composition of automated welding equipment:

1. Welding power supply, its output power and welding characteristics should be matched with the welding method to be used, and the interface connected with the main controller is installed.
2. wire feeder and its control and speed control system, for the wire feeder with higher requirements on wire feed speed control accuracy, its control circuit should add speed feedback
3. The welding machine head uses its moving mechanism, which consists of a welding machine head, a welding head support frame, a hanging type carriage, etc., and is used in a precision welding head mechanism. The drive system should adopt a servo motor equipped with an encoder.
4. Weldment movement or displacement mechanism, such as welding roller frame, head and tail frame turning machine, rotary platform and positioner, etc., precision moving position mechanism should be equipped with servo motor drive
5. weldment clamping mechanism
6. The main controller, also known as the system controller, is mainly used for linkage control of each component, control of welding procedures, setting, adjustment and display of main welding parameters. Control functions such as troubleshooting and man-machine dialogue can be expanded as necessary.
7. computer software, computer software commonly used in welding equipment includes: programming software, functional software, process software and expert systems, etc.
8. welding head guiding or tracking mechanism, arc pressure automatic controller, welding gun yaw and monitoring system
9. Auxiliary devices, such as wire feeding system, circulating water cooling system, flux recovery and conveying device, wire holder, cable hose, drag chain mechanism structure design and electrical control design these three parts.
10. Welding robots, also known as robotic arms, are an important part of automated welding equipment. Its main tasks include: welding, cutting, thermal spraying, carrying etc..

Application and value of automatic welding equipment in all-position welding

First, the automatic welding system industrial electronics is applied in the all-position welding, and the welding execution part is driven by the rotary pair to flexibly and reasonably change the posture of the welding torch, which is beneficial to the all-position welding work. At the same time, the motor power can be reduced while driving the same welding actuator. In the application, it is better to install the sensor at the welding position on the final stage deceleration shaft to detect the position of the welding gun. With this installation method, the control precision obtained is relatively high. In addition, by means of this memory on the automatic welding equipment, the parameters of the welding process and the weld tracking control program are stored, and the welding process parameters are stored in the arc welding power source, so that the advantages of the arc welding power source are further exerted. Through the cooperation of the two, it effectively solves various quality problems that may occur in all-position automatic welding operations.

Secondly, the driving of the welding torch is carried out by means of a stepping motor (the stepping motor is an open-loop control element stepping motor part that converts the electric pulse signal into angular displacement or line displacement). The digital input pulse model is effectively converted into a rotary motion by this motor. The accuracy of the component itself is high, and there is neither drift problem nor problems such as accumulated error. The application of this component in all-position welding not only keeps the rotational speed unchanged, but also controls the frequency signal to be relatively stable, and the torch displacement is more accurate.

Thirdly, in the all-position welding operation, the welding head and the arc welding power source are organically combined, which not only can achieve the purpose of full-position automatic welding, but also can reduce the price of the automatic welding equipment to a certain extent. In this way, not only can automatic welding be achieved, also the semi-automatic welding can be carried out by means of the arc welding power sources and the utilization of the semi-automatic welding torches.

Reverse osmosis (RO) is a water purification technology that uses a semipermeable membrane to remove ions, molecules, and larger particles from drinking water.

In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property, that is driven by chemical potential differences of the solvent, a thermodynamic parameter.

The reverse osmosis membrane technology can remove many types of dissolved and suspended species from water, including bacteria, and is used in both industrial processes and the production of potable water. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side. To be "selective", this membrane should not allow large molecules or ions through the pores (holes) but should allow smaller components of the solution (such as solvent molecules) to pass freely.

Advantages of ro membrane technology

1. Removes nonionic impurities and dissoved solids (i.e.organics,silica,bacteria)
2. Reduction of hazardous chemical storage and handling associated with ion exchange
3. Reductes loading on ion exchange systems:

Extends run lengths

Extends resin life

Reductions operating costs

Application range of reverse osmosis

Desalination

Dehydration

Concentration

Remove COD/BOD

Natural rubber, as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds, plus water.

Currently, rubber is harvested mainly in the form of the latex from the rubber tree or others. The latex is a sticky, milky colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called "tapping". The latex then is refined into rubber ready for commercial processing. In major areas, latex is allowed to coagulate in the collection cup. The coagulated lumps are collected and processed into dry forms for marketing.

Natural rubber is used extensively in many applications and products, either alone or in combination with other materials. In most of its useful forms, it has a large stretch ratio and high resilience and is extremely waterproof.

Centrifuged latex is processed into final articles by dipping, extruding, and coating. Different articles have different physical and chemical requirements, which means that the latex used in their manufacture must be modified by the addition of a great variety of substances that give each "formulation" its unique characteristics.

These characteristics are well-specified and must be carefully controlled.

Skim latex is generated during natural rubber processing centrifuged into fresh latex to become concentrated latex. Skim latex is a raw material for producing skim rubber block according to the low content of rubber particles in the range of 4-8% DRC.

Traditionally, skim latex is treated with sulphuric acid to produce cheap, low-quality rubber products of 5% skim rubber content. Not only does this method consume large quantities of the acid, which results in high production cost, more importantly, causing harmful pollutants to the environment.

JIUWU offers a safer, cheaper and greener option to produce skim rubber products of high quality. Through ceramic membrane filtration system, the rubber content in recovered skim latex can be concentrated to more than 15%, the same value in natural rubber without any form of chemical treatment. At the same time, permeate can be recycled.

JIUWU HI-TECH has many unique membrane applications and more than 50 Patents regarding ceramic membranes, Organic membrane filters, systems and process applications, in areas such as Food & Beverage, Bio-Pharm, Environmental and the Chemical Industry. We sincerely invite and welcome people from all around the world to invest and create more values together.

Automatic welding machine plays an important role in the application of various industries, and its application is expanding rapidly. In the modern industrial production, the mechanization and automation of the welding production process are the inevitable trends of the manufacturing industry. The automatic welding machine we provided, with more efficient, high welding precision and fast welding speed, can be widely used in many fields.

In the past 20 years, with the development of digital, automation, computer, mechanical design technology and the importance of welding quality, automatic welding has developed into an advanced manufacturing technology, and role automatic welding equipment plays in various industrial applications is more and more important, and the scope of application is expanding rapidly. In modern industrial production, the mechanization and automation of the welding production process is an inevitable trend in the modernization of the welding mechanism manufacturing industry.

According to the degree of automation, automatic welding system equipment can be divided into the following three categories:

1. Rigid automated welding equipment Rigid automatic welding equipment can also be called primary automatic welding equipment, most of which are designed according to the principle of open loop control. Although the entire welding process is automatically completed by the welding equipment, the feedback of the welding parameters during the welding process cannot be closed-loop feedback system, and the possible deviations cannot be randomly corrected.

2. Self-adaptive control automatic welding equipment The adaptively controlled welding equipment is a highly automated welding equipment, which is equipped with sensors and electronic detection lines, it can automatically guide and tracks the weld trajectory, and implements closed-loop feedback control of the main welding parameters. The entire welding process will be completed automatically according to preset procedures and process parameters.

Intelligent automatic welding system industrial electronics

It utilizes a variety of advanced sensing components such as vision sensors, tactile sensors, auditory sensors and laser scanners etc., and it makes uses of computer software systems, databases and expert systems with functions such as identification, judgment, real-time detection, calculation, automatic programming, welding parameters storage and the ability to automatically generate weld log files.

The composition of automated welding equipment:

1. automatic welding machine and supply, its output power and welding characteristics should be matched with the welding method to be used, and the interface connected with the main controller is installed.
2. wire feeder and its control and speed control system, for the wire feeder with higher requirements on wire feed speed control accuracy, its control circuit should add speed feedback
3. The welding machine head uses its moving mechanism, which consists of a welding machine head, a welding head support frame, a hanging type carriage, etc., and is used in a precision welding head mechanism. The drive system should adopt a servo motor equipped with an encoder.
4. Weldment movement or displacement mechanism, such as welding roller frame, head and tail frame turning machine, rotary platform and positioner, etc., precision moving position mechanism should be equipped with servo motor drive
5. weldment clamping mechanism
6. The main controller, also known as the system controller, is mainly used for linkage control of each component, control of welding procedures, setting, adjustment and display of main welding parameters. Control functions such as troubleshooting and man-machine dialogue can be expanded as necessary.
7. computer software, computer software commonly used in welding equipment includes: programming software, functional software, process software and expert systems, etc.
8. welding head guiding or tracking mechanism, arc pressure automatic controller, welding gun yaw and monitoring system
9. Auxiliary devices, such as wire feeding system, circulating water cooling system, flux recovery and conveying device, wire holder, cable hose, drag chain mechanism structure design and electrical control design these three parts.
10. Welding robots, also known as robotic arms, are an important part of automated welding equipment. Its main tasks include: welding, cutting, thermal spraying, carrying etc..

Application and value of automatic welding equipment in all-position welding

First, the automatic welding equipment is applied in the all-position welding, and the welding execution part is driven by the rotary pair to flexibly and reasonably change the posture of the welding torch, which is beneficial to the all-position welding work. At the same time, the motor power can be reduced while driving the same welding actuator. In the application, it is better to install the sensor at the welding position on the final stage deceleration shaft to detect the position of the welding gun. With this installation method, the control precision obtained is relatively high. In addition, by means of this memory on the automatic welding equipment, the parameters of the welding process and the weld tracking control program are stored, and the welding process parameters are stored in the arc welding power source, so that the advantages of the arc welding power source are further exerted. Through the cooperation of the two, it effectively solves various quality problems that may occur in all-position automatic welding operations.

Secondly, the driving of the welding torch is carried out by means of a stepping motor (the stepping motor is an open-loop control element stepping motor part that converts the electric pulse signal into angular displacement or line displacement). The digital input pulse model is effectively converted into a rotary motion by this motor. The accuracy of the component itself is high, and there is neither drift problem nor problems such as accumulated error. The application of this component in all-position welding not only keeps the rotational speed unchanged, but also controls the frequency signal to be relatively stable, and the torch displacement is more accurate.

Thirdly, in the all-position welding operation, the welding head and the arc welding power source are organically combined, which not only can achieve the purpose of full-position automatic welding, but also can reduce the price of the automatic welding equipment to a certain extent. In this way, not only can automatic welding be achieved, also the semi-automatic welding can be carried out by means of the arc welding power sources and the utilization of the semi-automatic welding torches.

Performance characteristics and working principle of Chemical Ground Electrode:

1. Chemical ground electrode
2. Existing soil
3. Special filler
4. Ions diffuse around
5. Expand the conductive range of the soil

installation earth electrode is a new type of grounding system suitable for all kinds of places with high grounding requirements and difficult grounding engineering.

The chemial grounding electrode system  consists of advanced alloy compounds, with a copper tube on the outside to ensure maximum conductivity and long service life. The filling material inside the conductor contains special ionic compounds, which can absorb moisture in the air adequately. Active ions can be effectively released into the soil through the deliquescence, and interact with the moisture in the soil and air to further promote the external slow release and drag reduction of conductors, and to maintain the long-term stability of the resistance value. Compounds in conductors are gradually combined in colloidal transparency over time.

By utilizing the conductivity of the colloidal compound, the entire system can be ion-exchanged for a long time, thus forming an ideal electrolytic ion grounding system. After the slow-release filler in the conductor is embedded, the grounding resistance will gradually decrease, reaching a stable value within six months to one year, and the embedded slow-release process can last for several years. The main connecting parts of the ion grounding electrode are hot-melt welded, which has overcome other connection methods and easy connection loosening.

The connecting wire is a copper clad steel copperweld stranded wire with a section of 95 mm2 and a length of 3 m and is crimped to the grounding terminal/copper lug to facilitate connection with the copper clad steel grounding.
