Installation and use of fan

1. Before installation, all parts of the fan should be checked, especially whether the impeller is damaged, whether the connection part is loose, whether the clearance between the impeller and the air inlet is uniform and no friction and collision. If any abnormality is found, it should be repaired in time before installation.
2. After installation, check whether there are tools or sundries left in the fan, whether the connecting bolts are tightened, and whether the impeller is flexible. The test run can be carried out after everything is normal.
3. Metal mesh should be installed at the inlet of the fan pipe to prevent foreign matter from inhaling and ensure the safe operation of the fan.
4. The fan must be reliably grounded to prevent the danger of leakage.

5.The pipe connection of the fan should be naturally matched without forced connection. The weight of the pipe connecting the inlet and outlet should not be added to the fan to prevent the deformation of the body and affect the normal use.

Fan maintenance

1. The power used by the axial circulation fan refers to the power when the fan is fully closed in and out under the specified working conditions and with a certain amount of reserve. For safe operation, if the valve is installed in the inlet or outlet pipeline, the valve should be opened when the fan is started. After normal operation, the valve should be gradually turned down until the working condition is reached, and the current or power of the motor should not exceed the specified value.Otherwise the motor is in danger of burning down!
2. In order to avoid the failure of the fan due to improper maintenance, the maintenance of the fan must be strengthened to prolong its service life. Some points should be noted:
3. Only under normal conditions can the fan operate.
4. Regularly check whether all parts of the fan are normal. Dispose of any damage in time.
5. Regularly clean the dust and dirt in the pipes and fans.
6. The repair of the fan is not allowed to be carried out in operation.
7. If abnormal phenomenon is found in the operation of the fan, it should be stopped immediately for inspection.

Main cause and treatment of fan failure

Instructions for use of axial fan 

Axial flow fan is the air flow in the same direction as the shaft of the blade (that is, the flow of the wind is parallel to the shaft), such as electric fan, air conditioning fan is axial flow mode of operation. Axial flow fan, also called local fan, is a kind of fan commonly used in industrial and mining enterprises. Its motor and blade are in a cylinder, and the shape is a cylinder. It is used for local ventilation, convenient installation, obvious ventilation effect, safety, and can be connected to the air duct to send the air to the designated area. The use environment should always be kept clean, the surface of the fan should be kept clean, and there should be no sundries in the inlet and outlet. Regularly eliminate dust and other sundries in the fan and pipe.

It can only operate under the condition that the fan is fully operated. In parallel, it is necessary to maintain sufficient capacity of the power supply facilities, stable voltage, and strictly prohibit phase-missing operation. The power supply line must be dedicated line, and should not be supplied with temporary line for a long time.

If the fan is found to have abnormal sound, the motor is seriously heated, the shell is charged, the switch trips, can not start and other phenomena during the operation, it should be stopped immediately for inspection. In order to ensure safety, maintenance is not allowed in the operation of the fan.

After maintenance, the test run should be conducted for about five minutes, and the operation should be started after confirming that there is no abnormal phenomenon. According to the use of environmental conditions, the bearings should be replenished or replaced with lubricating grease from time to time (it is not necessary to replace lubricating grease during the service life of the motor closed bearing). In order to ensure good lubrication of the fan during operation, the refueling times should not be less than 1000 hours per time. ZL-3 should be added to the closed bearing and motor bearing

Lithium-based grease fills 2/3 of the inner and outer rings of the bearing. The fan should be stored in a dry environment to avoid dampness of the motor. When the fan is stored in the open air, rainproof measures shall be taken. In the process of storage and handling, the fan should be prevented from bumping, so as to avoid damage to the fan.

Small axial flow fan is a very widely used fan type, can bring good use effect, and in order to you can better buy the use of small axial flow fan, to several different types of small axial flow fan, I believe that it can certainly bring good use effect.

Small axial fan - the concept of axial fan

Axial flow fan is very widely used. It is the air flow in the same direction as the shaft of the blade, such as electric fan. The air conditioning fan is the axial flow fan. It is called "axial flow" because the gas flows parallel to the fan shaft. Axial fan is usually used in the flow requirements of higher and lower pressure requirements of the occasion. The axial fan holds the position and moves the air. Axial flow fan is mainly composed of fan impeller and chassis, simple structure but very high data requirements.

Small axial fan - small axial fan there are several kinds

Square small axial fan

一、The motor and the blades of the square wall axial fan are in a cylinder, and the shape is square, which is more convenient for wall installation than the cylinder fan. The machine adopts CAD/CAM design, with low investment cost, large air volume, low noise, low energy consumption, smooth operation, long life, high efficiency. The machine is made of square, beautiful appearance, wall reserved square hole installation is convenient, the outlet is equipped with vertical louvers, shutters automatically up and down to achieve dustsproof, waterproof, beautiful and generous; Can blow air, is the best choice for cooling and ventilation of modern workshop, but also can draw air, environmental protection, energy saving square axial flow fan, cooling damp damp will become the main stream of ventilation and cooling equipment market products. Widely used in industrial and mining enterprises, civil buildings, gymnasium, animal husbandry, a variety of entertainment places wall exhaust.

二、low noise small axial fan

Low noise wall axial flow fan USES, from the perspective of the sound source, low speed, high pressure coefficient, the design method of the research into a wide blade, big chord length, space distortion of tilting blade, with dedicated fan motor, fan shell, with a sound internal absorption material, with obvious low noise, big air volume, power saving, small vibration, the advantages of beautiful shape, is a kind of efficient, Energy-saving axial fan. Widely used in factory buildings, warehouses, offices, residential and other places of wall exhaust, pipeline air supply.
