Semi Side Dump Trailer is suitable for a case where the vehicle is difficult to turn around or needs to be changed with the direction of unloading. According to a different needs, the cargo box could be regular rectangle shape, U shape, multiple doors type, etc.. What should we pay attention to when choosing a Semi side dump trailer sales? Generally, the height of the panel of the Semi Side Dump Trailer does not exceed 0.6 meters. The hydraulic cylinder is an important part of the Semi Side Dump Trailer.

According to the different tonnages of the load, there are generally 110, 125, 130, 150 and other diameters. Generally if standard load does not exceed 60 tons then use type 110 with 5+1 (5 Lifting cylinder, a shifting cylinder) or 4+1 of 130; heavy-duty 80-120 tons generally use 6+1 or 7+1 tons of 150 cylinders. The displacement cylinder is generally a 160 or 180 cylinder. The hydraulic cylinder bracket carries a large part of the weight of the cargo when it is lifted, and the firmness of the bracket is important. The shaft of the joint between the hydraulic cylinder and the sub-frame should be well protected, otherwise it will be easy to bend. In addition, the diagonal reinforcement is important, and the more the support points, the higher the reliability. The diagonal bracing, when rolling over, the majority of the weight of the cargo is supported by the diagonal braces. Once the bracing is problematic, it is easy to cause a rollover accident, so the reinforcement of the diagonal braces is very important. Generally, the 13-meter rollover dump truck has 5 pivot points. The girders are very important for a semi-trailer, and the main I beam for Semi Side Dump Trailer are generally larger than the main I beam of vans type semi trailer of the same weight. The reason is that when Semi Side Dump Trailer is turned sideways, the main I beam are unevenly stressed, and the longitudinal beams on one side of the main I beam are stressed, and the requirements for the main I beam are higher than those of ordinary semi trailer. Unlike Semi End Dump Trailer, Semi Side Dump Trailer is suitable for cargo with a small rest angle. However, Semi Side Dump Trailer can load more than Semi End Dump Trailer.

At present, pvc membrane welding machine has been widely promoted in a number of plastic welding industry. Various welding defects are inevitable in the process of use. In this article, it mainly analyzes how to solve the problems in debugging or welding.

1.Crush and bruise

Pressing injury and abrasion are common problems in the process of pvc membrane machine. Sometimes it's not so serious, and it just gets white or marks. When you encounter such problems, the first thing to do is to ensure that the location of the tooling is not out of alignment. First let off the air of the cylinder, press down the welding head, and carefully observe whether the welding head position of the scratch is correct. If the welding head is in the correct position, or if the abrasion or compression occurs on the support (or lower cover), then it is necessary to observe whether there is any interference between the tooling and the product. If it is old tooling, it is suggested to clean the tooling with alcohol at this time. If it is a new fixture, lightly rub the scratch (especially at the bottom of the step) with sandpaper to prevent burrs. In addition, observe whether the air pressure of the cylinder is too large during welding, whether the film of the pad has not been changed for a long time during welding, or whether there are foreign bodies stuck on the film.

If the above work is done, the pressing injury still exists, it can be basically judged as the interference of tooling. At this time, the mold shall be modified according to the size and location of the pressing injury:

(1)slight pressing injury. File the sharp Angle of the tool at the corresponding place of the tool, blunt the sharp Angle of the tool, and then use sandpaper polishing;

(2)the pressing injury is serious, but there is no welding rib at the corresponding place. Rub off the interference part of the fixture with an air abrasive rod (be careful not to touch other parts, especially the root part of the air abrasive rod, which may be rubbed off other places without being noticed). After grinding, make it smooth with whetstone and buff with sandpaper;

(3)severe crush injury. If there is welding rib in the corresponding place, or if there is serious pressing injury and the interference part is very large, please consult with the designer. Have the processing center dealing with the modified drawing and contact the relevant personnel to confirm whether there is a problem with the injection molding, or whether to improve the product structure.

2.Material overflow

If there is any overflow in the welding process of pvc membrane welding machine, do not debug or modify the welding parameters right away. First measure the size after welding, and compare it with the normal value. Adjust according to the difference.

3.Insufficient welding strength

If it is old tooling, first stick the product on the welding head, observe whether the gap between the product and the welding head is too large in the weak welding place, to determine whether the welding head is worn; if it is a new tool, please scan it with the welding head, observe its frequency, power and curve, and make sure there is no problem with the welding head.

1. Putzmeister 42 meters concrete pump, Volvo chassis, 4 axle x-leg, classical 4 booms, high working stability.
2. Manufacture Date is November of the year 2005.
3. Maintenance completed new tires of the complete machine. Hopper maintenance; Finishing lubrication pipeline, circuit, and hydraulic circuit. Whole line arrangement, old pipe and line changed, pressure debugging for 8 hrs and in very excellent condition.
4. Import quality, trustworthy. No formalities and higher cost performance.
5. The first class of machine and make sure each of everything is in good condition, must zero fault when leaving the factory, reduce working pressure and cost from clients.

Only with the stable lower plate is the pump truck safe. The arm-frame pump truck supporting leg should be paid much attention.

Just like kung fu, if your "lower plate" is not strong enough, you can easily be pushed down. Whether putzmeister second hand pump trucks' legs can firmly "plunge" on the ground, is the priority of the safe operation of the arm gantry pump truck.

1. Protect yourself and others from dangerous areas

When opening or closing the leg of the gantry Putzmeister stationary concrete pump, the rotation range is a dangerous area. People may be hurt in the range. When carrying out this operation, you should be careful of yourself and the people nearby.

2. To strengthen of the overlapping location is great. The supporting legs should be extended in place.

The legs of the arm pump truck all have fixed strengthening positions. Only when the legs are opened and extended in place can these strengthening positions give full play to the strength. Otherwise, the supporting legs will be in danger of breaking. Pay attention to the arrows on the legs and ears as you extend them.

3. Communicate with construction personnel in advance and don't "step on empty"

The gantry pump truck must be supported on a solid ground. If the maximum pressure of the supporting leg is greater than the allowable pressure on the ground, the supporting plate or auxiliary square shall be used to increase the supporting surface area. In addition, communicate with the person familiar with the construction site before supporting the leg, and make sure the leg is not above the sewer.

4. Keep a safe distance to prevent ground collapse

Adequate safety distance should be set aside to prevent ground collapse when support is near a pit or ramp.

5. The arm pump truck must be leveled and must not exceed 3 degrees

After the support is completed, make sure that the maximum horizontal deflection of the gantry Putzmeister truck mounted concrete pump is no more than 3 degrees. Generally speaking, the direction of the extension of the arm frame will be raised higher during the construction process, leaving a surplus for the subsidence after the extension of the arm frame. Currently, the arm mounted pump truck is usually equipped with an electronic level and alarm device. Once the arm mounted pump truck tilts too high, the alarm will sound to remind the operator. Before extending the armrest, make sure the legs are properly attached.

6. Remote control ensures the safety. Do not be too high from the ground

Upon confirmation of all the leg under the condition of reliable and efficient, make confirmation on the leg safety with the first and second boom. The specific approach is to stretch one arm frame, making the open Angle at 90 degrees. Then let two booms in one meter off the ground. Move one arm up and down in the position of four legs, check whether the corresponding arm bracket and diagonal arm bracket are safe.

7. If water enters under the leg, the arm shall be returned for safety

In case of the occurrence of rain water, oil cylinder leakage of supporting legs and factors reducing the stability of supporting legs, the arm shelf should be closed immediately. After the problem is eliminated, the supporting legs should be put up again according to the requirements.

In addition, when supporting the arm pump truck, it is better to keep the tire off the ground by 5 cm or so. Otherwise, the swing of the s swing tube of the arm pump vehicle and the shaking of the vehicle caused by the impact of pressure in the tube will damage the vehicle driving mechanism.

According to the physical and electrical properties of optical cables, the laying of optical cables must meet certain requirements. In addition, the laying of optical cables in different environments also have their own requirements.

The laying of optical cables shall strictly comply with the following requirements:

(1) Length and integrity: The length of each cable should be controlled within 800m, and there is no relay in the middle.

(2) Minimum installation bending radius of optical cable: under static load, the minimum bending radius of optical cable is 10 times than the diameter of optical cable; under load conditions during wiring operation, such as pulling the optical cable out of the pipe, the minimum bending radius is 20 times than the diameter of optical cable; the minimum installation bending radius of four-core optical cable must be greater than 2in (5.08 cm). 

(3) Installation stress: The maximum installation stress applied to 4/6 core cable shall not exceed 100lbf (45kgf); when multiple 4/6 core cables are installed at the same time, the maximum installation stress per cable shall be reduced by 20%. For example, for 4x4 core cable, the maximum installation stress shall be 320lbf (144kgf).

Explanation: It is required that the traction force of the cable should not exceed 80% of the allowable tension of the cable, and the maximum instantaneous traction force should not exceed the allowable tension of the cable. The main traction force should be applied to the strengthened components of the cable, and the fiber can not bear the tension directly.

(4) Installation pulling force of optical fiber jumper: the maximum pulling force of single-core soft wire is 27 LBF (12.15 kgf), and the maximum pulling force of double-core soft wire is 550 LBF (22.5 kgf), and the distance of interconnection equipment should not exceed 100 ft (30 m).

(5) Judging the A.B end of optical cable: Before construction, we must first judge and determine the A.B end of optical cable. A-terminal should be oriented towards network hub
direction, while the B-terminal should be oriented to the user's side. The end of the laying cable should be in the same direction, and it must not be mistaken.

(6) No matter laying optical cables in buildings or between buildings, separate pipe holes should be occupied. If the original pipe and copper cable are used together, the plastic sub-pipe should be put through the hole. The inner diameter of the plastic sub-pipe should be 1.5 times than the outer diameter of the optical cable. The optical cable should be laid in the plastic sub-pipe, and the same sub-pipe should not be used with the copper cable. When laying optical cables are in parallel with other weak current systems in buildings, they should be laid separately and fixed, and the minimum net distance between the cables should meet the design requirements.

Describe the new technology of hearing aid - Bluetooth Style

Hearing Amplifier Bluetooth technology has been launched by manufacturers 3 or 4 years ago. Due to the lack of understanding of the majority of users and the high price of relevant products, few of them are used. With the introduction of hearing aids with Bluetooth technology by various manufacturers in the past year or two, the price of hearing aids with this technology has been reduced to a level acceptable to a considerable number of customers, and the number of users has gradually increased. In the past, ordinary hearing aids did not work well when answering telephone calls, for two main reasons:

One is that the voice of the telephone needs to be transmitted through air to the microphone of the hearing aid. Because when a user makes a phone call, the receiver and the microphone of the hearing aid are always not very accurate, which causes the sound signal attenuation of the phone. Even though some hearing aids use inductance, the sound energy transmitted to the hearing aid is incomplete because the distance and the electromagnetic energy of the telephone are not enough.

Second, when making a phone call, the receiver of the phone can only be placed next to the microphone of one ear. At the same time, the microphone of the hearing aid can receive the sound made by the user around, resulting in poor signal and noise when making a phone call. For these reasons, a significant number of users are less effective at making phone calls with hearing aids, and some are even less clear than without them.

The combination of hearing aid and Bluetooth technology solves the problem well.

Hearing aids with Bluetooth technology do not require the user to move the phone's receiver to the microphone of the hearing aid. There is a wireless receiving module in the hearing aid, and a module (with Bluetooth signal reception and common wireless signal transmission functions) is added outside the hearing aid. This module is the same size as the matchbox (different brands have slightly different sizes), or it is hung on the chest or in the pocket. The main function of the module is to receive the Bluetooth signal from the end of the phone and transmit the audio information of the signal directly to the binaural hearing aid. This process has several advantages, which completely overcome the defects of the above mentioned SNR and inaccurate position. First, the sound in the telephone is transmitted wirelessly to the user's hearing aid with almost no loss, ensuring that the sound energy does not decrease.

The second is that he can direct the voice from the phone to the user's two hearing aids, so that both ears can hear the voice of the other person inside the phone; In most cases, the speech recognition rate of binaural listening is much higher than that of monaural listening. The third point is that in the Bluetooth mode and the ordinary wireless transmission process, the voice in the phone is equivalent to directly into the hearing aid, without any noise interference in the environment of the phone receiver, which greatly improves the signal-to-noise ratio. Based on the above three points, Bluetooth Style Hearing Amplifier has made a lot of changes in the effect of telephone answering, which has been praised by many users.

MFI Magnetic flux leakage test refers to the formation of a leakage magnetic field on the surface of a test piece after it is magnetized due to defects on the surface or near-surface of the test piece. People can detect defects by detecting changes in the leakage magnetic field.

Briefly describe the limitations of the magnetic flux leakage detection method.

The limitations of the magnetic testing equipment are as follows:

1. It is only applicable to ferromagnetic materials.  
2. Detection sensitivity is low.
3. The quantification of defects is rough.  
4. Due to the shape of the workpiece to be inspected, the leakage magnetic field method is not suitable for detecting test pieces with complicated shapes because the sensor detects the leakage flux.  
5. Magnetic flux leakage is not suitable for cracking very narrow cracks, especially closed cracks. It was found in the experiment that cracks with very narrow cracks, magnetic particle flaw detection and magnetic flux leakage inspection failed to produce an indication of injury and injury.

Briefly describe the application range of magnetic flux leakage detection technology.

1. The application of magnetic flux leakage detection in the steel industry: in steel mills, it is mainly used for inspection of steel structural parts, billets, round bars, bars, steel pipes, welds and steel cables. Make sure the finished product is in good condition. On many occasions, users will not receive steel products that have not been inspected by steel mills and third parties.  Users often use non destructivetesting equipment before manufacturing, which ensures the manufacturer's technical requirements for the product. Such inspections are often carried out by an independent inspection company or the user's quality assurance department.  
2. The application of magnetic flux leakage detection in the petrochemical industry: the installation of oil and gas pipelines (including buried pipelines), storage tank floor or the recovery of oilfield steel pipes.  
3. Other applications: regular in-service inspection of used steel cables, wire ropes, and chains.

BKN's benchtop magnetic flux leakage testing equipment are capable of detecting workpieces efficiently and accurately.

Safety issues should be paid attention to in the construction of putzmeister used putzmeister pump

• Keep the water tank full of clean water, and check and deal with it in time when finding the water quality is cloudy and there are many sand grains.
• Bolts of the putzmeister 42mshall be fastened, pipe joints shall be tightly sealed, and protective devices shall be complete and reliable.
• The control, high-speed handle, handwheel, control lever and cock shall be in the correct position. The hydraulic system should be normal and free of leakage.
• When the pumping system is under pressure, it shall not open any delivery pipe or hydraulic pipe. The safety valve of the hydraulic system shall not be adjusted arbitrarily, and the accumulator can only be filled with nitrogen.
• After the operation of concrete tow pumps, all the commercial concrete in the hopper and pipeline must be exported, and then the putzmeister concrete pump truck, hopper and pipes shall be cleaned. When rinsing the pipe with compressed air, no one can stand within 10 meters in front of the outlet end of the pipe, and the foam rubber and sand particles rushed out should be collected by metal net basket.
• It is strictly forbidden to flush the pipe of the placing boom with compressed air. The folding and shrinking of the placing boom should be done in order.

If the time of hf welding pvc is too long, there are often some faults. After the failure occurs, users must find and deal with it in the first time and solve it in time. For different faults, the solutions are different. The following solutions are listed here for everyone:

If the welding effect is not ideal or it cannot be welded or the workpiece is damaged when it is in the process of hf welding pvc, we can not think that it is the problem of equipment. It could be other problems. For example: equipment setting error, blown fuse and so on may happen.

Common failure analysis and solutions:

1. If there are bubbles in the process of hf welding pvc with workpieces, it is not directly related to the equipment usually.

(1) situation of loose connection

it is possible that the flow meter of the gas regulator has been damaged or blocked with sundries.

(2) there may be sundries on the surface of the workpiece.
