There are three types of belts commonly found in automobiles: car fan belts, ribbed belts, and timing belts.

Automobile belt installation location: In automotive applications, it is mainly installed on the crankshaft of automobile engines to cams, water pumps, generators, air-conditioning compressors, power steering pumps and other positions.

1. The fan belt is a belt driven by a crankshaft. Its main purpose is to drive the engine fan and water pump.

2. The V-ribbed belt, also called air-conditioning belt, is used to drive the generator, air-conditioning compressor, and steering booster pump, and is hung on the crankshaft belt pulley, which is tightened by the air-conditioning belt tensioner. When this belt is damaged, the source will feel the power is heavy and there is no steering power. If the air conditioner is turned on, the air conditioner compressor will not start, so it cannot be cooled.

3. The timing belt is an important part of the engine's gas distribution system. It is connected to the crankshaft and matched with a certain transmission ratio to ensure the accuracy of the intake and exhaust time. The function of the timing belt is to open and close (time) the ignition sequence (time) of the piston stroke (up and down movement) of the valve when the engine is running. Under the action of "timing", it is necessary to maintain "synchronous" operation at all times.

The engine drives various auxiliary mechanisms through the belt drive, such as the compressor of the air conditioner, the power steering oil pump, and the alternator. If the belt slips or breaks, the related auxiliary mechanisms will not work properly, which will affect the normal use of the car lane. Therefore, it is necessary to regularly check the transmission belt.

There are many types of car engine belts. The type and length of the belt will be very different depending on the model and the location of use. It is best to provide the accurate model and engine model when buying. It is best to have the old belt removed for reference. Be sure to choose a car belt suitable for your vehicle.

When choose industrial fans, the user maybe confused, and do not know which kind is better. While a good industrial fan is not only meeting performance requirements,but also involving safety and noise.

Five safety standards for large industrial fans as follow:

1. Check whether the motor head and the whole machine will shake when rotating in low and medium speed gears, especially in high speed gears.

2.After a long period of high speed rotation (at least 1 hour later),perceive the heat generating from the front shell of the industrial fan by hand or other instruments. If it feels very hot, it indicates that the industrial fan motor has poor heat dissipation performance.

3, look at the speed, power, air volume, noise and other parameters (industrial fan speed, power, air volume and noise is proportional, that is to say, the higher of fan speed, the power and air volume are greater,  the noise will also become larger,part ventilation cooling effect is better).

4, see whether there is intermittent pause in high speed rotation around the head, whether the head is not in place.

5. Gaxiao industrial fan is designed with brand-new mortise and tenon structure connection mode, which has the function of real anti-collision.

Then, we need to observe the industrial fan noise. What are the sources of noise?

1.Vibration. If the rotor of the fan rotates, the rotor's physical center of mass and the center of inertia of the rotating shaft are not on the same axis, it will lead to the imbalance of the rotor.The close distance between the physical center of mass of the rotor and the center of inertia of the rotor is called eccentricity, and the imbalance of the rotor will result in eccentricity. When the rotor rotates, a force acting on the support of the rotor will be generated due to the action of centrifugal force, resulting in vibration, and vibration will be transmitted from the base path to all parts of the machinery.

2.Wind noise. At the rotating of large industrial fans, the blades are periodically subject to the pulsating action, resulting in noise;On the other hand, the blade itself and the pressure on the blade are not evenly distributed, so it is easy to disturb the surrounding gas and parts during the rotation, which also constitutes the rotation noise.In addition, vortex noise is generated by the pulsation of pressure distribution on the blade , which is due to gas flowing through the blade generating the turbulent attachment layer, vortex and vortex separation.The noise of these 3 reasons can be called  "cut wind noise", the fan with general wind & big wind pressure, its cut wind noise is bigger also.

3. Abnormal sound, wind noise sounds like just the wind, but the abnormal sound is different, during the rotating of industrial fan, if except to the wind, there are still other sounds, you can judge the industrial fan has abnormal sound.Abnormal sound may occur due to foreign matter or deformation in the bearing, collision for improper assembly, or uneven winding of the motor resulting in looseness.The service life of fan is working time of radiator product working normally without breakdown , high grade industrial fan use life can achieve tens of thousands hours commonly.

The size of noise when the fan works, affected by many factors, the unit is decibel (dB).When measuring the large fan’s noise, it shall be carried out in the muffler room with noise less than 17dB, one meter away from the fan, and aligned with the fan's air inlet along the direction of the fan shaft, and measured in A weighted way.

4. The spectral characteristics of industrial fan noise are also very important. Therefore, it is necessary to record the noise frequency distribution with a spectrograph. Generally, the noise of the fan should be as small as possible and there should be no abnormal sound.Fan noise is related to friction and air flow.Fan rotate speed is higher, wind quantity is bigger, the noise that causes also can be bigger, the element of fan’s vibration also cannot ignore additionally.Of course, a high-quality fan will have very little vibration of its own, but the first two are difficult to overcome.To solve this problem, try using a larger fan.In the case of the same air volume, the working noise of the large fan at a lower speed should be less than that of the small fan at a higher speed.

Nowadays, many physical factories use industrial large fans to promote the air circulation of the production workshop and reduce the temperature of the workshop. This solves the problem of how to choose large industrial fans. Many physical factories will purchase multiple fans in batches and install them in suitable parts of the workshop. . So what do you need to pay attention to when installing a new market quotation for huge industrial fan? #hvls fan #high volume low speed fan #industrial ceiling fan #ceiling industrial fan

First, use the steel bars to firmly fix the fan to the ceiling

The huge industrial fan consists of three main components: the fan blade and the fan head and the suspension device. Unlike ordinary household fans, industrial large fans usually need to be suspended and mounted on the top of the use scene. If the fan is not firmly fixed to the roof, it may cause the fan to fall during the later use. Therefore, it is necessary to fix the work when installing the industrial fan. It should be used on the ceiling of the factory floor. The steel bar hook securely fixes the assembled fan. If there are no reserved bar hooks on the ceiling of the production workshop, the fan should be used to lift the fan on the ceiling.

Second, connect each line accurately

The normal operation of large industrial fans requires the use of power supplies in addition to the support of various important components, and the manufacturers generally reserve the fuses of the live and neutral wires on the suspension of the fan. In the case where the connection between the fan head and the installation scene is inaccurate, a short circuit may occur. Therefore, when installing a large industrial fan, it is necessary to check the connection status of each line. In addition, it is necessary to cut off the installation scene in advance when wiring. Power supply to avoid accidents such as electric shock.

The introduction to the matters needing attention when industrial fan installation is coming to an end. In fact, the installation precautions for industrial large fans are not only the two aspects of suspension and wiring. In addition, the installer should also pay attention to installing the rubber wheel matched with the industrial large fan on the corresponding position on the fan instead of directly discarding it.

As a common industrial machine for space ventilation and personnel cooling, the industrial HVLS fan is a large space widely used in industrial plants, logistics and warehousing, waiting rooms, exhibition halls, stadiums, supermarkets and elevator industry. Industrial large fan can push a large amount of airflow to the ground and form a certain level of airflow level movement on the ground. This contributes to the overall air circulation, which has the advantage of a full range of ground coverage and a three-dimensional cycle of air.

Large industrial fan is available in diameter up to 7.3 meters. Streamlined blades made with aerodynamics and advanced technology can drive a large amount of air with only 1.5 kW, creating a large-area natural breeze system that functions as both ventilation and cooling. Compared with traditional HVAC and small high-speed fans, it has unparalleled application and is a solution for high space ventilation and cooling.

Every year at the end of the mall, supermarkets will hoard a lot of goods for Spring Festival. If the warehouse building where the food is stored is humid, it is easy to cause excessive microorganisms, and the product is mildewed and deteriorated. In order to reduce unnecessary losses, we must take effective preventive measures in advance. In fact, heating is installed in the supermarket in winter, and the temperature is relatively high after entering. If you use a big air industrial fan for ventilation, it is a good choice. The big air industrial fan uses the principles of modern aerodynamics to enhance the comfort of air flow, while also controlling the condensation of air on the ground or metal surfaces, reducing bacteria and mildew. It can make your work environment more refreshing and comfortable. In the rainy weather, the air circulation in the storage workshop can be maintained, so that the quality of the product is guaranteed.

In addition, I would like to remind everyone that in addition to the use of big air industrial fan, the following points should be noted when storing food:
(1) The places and equipment where food is stored shall be kept clean. Equipment should be free of mold spots, rat marks, flies, cockroaches, and should not store toxic or hazardous materials (such as rodenticides, detergents, disinfectants, etc.) and personal household items.

(2) Food should be classified and stored in separate shelves. It should be more than 10cm away from the wall and the ground, and should be inspected regularly. The use should follow the principle of first-in-first-out, and the deteriorated and expired food should be removed in time.

(3) The temperature of food refrigerated and frozen storage shall respectively meet the temperature range requirements of refrigeration and freezing.

The big air industrial ceiling fans belong to a kind of ceiling fan which is produced by utilizing the dynamics of ambient air. It is highly praised by users in the market. The reason is that professional big air industrial ceiling fans aggregate various advantages and can effectively provide ventilation for a variety of different venues. Let's take a look at the main reasons for the popularity of the big air industrial ceiling fans.

First of all, this big air industrial ceiling fan is cost-effective and energy-saving. Although it is a high-tech ceiling fan, the design of energy-saving and environmentally friendly materials will not be too high in price, and the low speed will not cause users to consume high power. Moreover, it has a long life, so it is more cost-effective and more popular with users.

Then, the big air industrial ceiling fans run very smoothly and are safe to use. All kinds of fasteners are one-piece installation. Moreover, this ultra-large energy-saving ceiling fan can run continuously for a long time, improving the space environment for users. It does not cause the motor to overheat and malfunction due to long running time. The ceiling fan itself has a cooling function, and the low speed operation does not cause too much heat, so users are willing to choose.

What is the cause of the sweltering in the workshop?

1. The plant is too high to install air conditioners;
2. The workshop space is too large, and the general refrigeration equipment can’t meet the requirements;
3. Machine heating, etc.

As far as the use of the big air industrial ceiling fan itself is concerned, the fan with a large fan blade generally has a large electric power and consumes a large amount of electric energy. The power consumption of the electric fan is proportional to the rotational speed of the fan blade. For example, a large industrial ceiling fan of 400 mm consumes 60 W when using a quick gear. When it uses slow gear, it consumes only 40W. The fastest power of the same electric fan is 40% different from the power consumption of the slowest gear. Therefore, usually open the fast gear first, and then use the slow gear after cooling down, you can reduce the power consumption of the industrial ceiling fan. When the air volume meets the requirements for use, try to use the middle or slow gear.

The fan blades of big air industrial ceiling fans are made of aerospace aluminum alloy. The blade connection and the hub connection are required to have sufficient strength and structural safety. It is a protective measure to prevent the blade from being up, down and broken! The industrial ceiling fan is directly fixed on the steel beam of the roof structure, without welding and processing, and does not affect the structure of the building itself. The speed is lower than 60 rpm, and the air volume is over 10,000 cubic meters per minute! Most importantly, it consumes up to 1.5 kWh per hour. It saves money!

The big air industrial ceiling fans that are energy-saving, environmentally friendly, and practical are the most demanding users and markets, but the most basic is to meet the requirements in terms of quality. If the user can purchase  the big air industrial ceiling fans of the factory direct sales, it will be more secure in quality and the first-hand source can save more cost.

Gaxiao attended PHILCONSTRUCT 2018 in Manila during 8th to 11th at SMX center, which is a professional show regarding construct and ventilation in Philippines.
Demanding of HVLS Fans is growing fast in Philippines that more and more people need HVLS fans instead of traditional ceiling fans. It could help industries there save cost and improve efficiency.
