Maintenance methods of oil filter of rotary fan and reasons for high bearing temperature
How to solve the problem after the rotary fan enters the water:
1. Drain the accumulated water in the fan room.
2. Treatment method of the motor: remove the motor from the base, open the front and rear end covers of the motor, take out the rotor, and screw all the end cover screws into the screw holes at both ends of the stator to prevent the winding from being damaged when the stator is erected. Stand the stator up and expose both ends to the sun for 12 hours, and measure the insulation resistance between the winding and the shell with a megger, which shall not be less than 20 megohm.
3.風機主機處理方法: 把回油管從底座處拔下，放掉主機及空氣室內的油和水， 取下空氣濾清器，用手快速正向轉動風機帶輪10轉左右后，從進風口慢慢倒入機油同時不斷正向轉動風機帶輪，排出所有清洗油。
3. Treatment method of fan host: Unplug the oil return pipe from the base, drain the oil and water in the host and air chamber, remove the air filter, quickly rotate the fan pulley in a positive direction by hand for about 10 turns, slowly pour oil from the air inlet, and constantly rotate the fan pulley in a positive direction to discharge all cleaning oil.
4. Treatment method of oil tank: use a wrench to remove the oil pointer first, then remove an oil filter, tilt the base, try to drain the waste oil in the oil tank, and clean the oil tank with new engine oil at the same time. Install the oil filter, oil return pipe and air filter, inject oil into the oil tank to 3/4 of the oil tank, and tighten the oil pointer.
Reasons for high bearing temperature of rotary fan:
1. The temperature of the fan bearing is too high, which may be caused by the violent vibration of the chassis. The fan bearing assembly itself has an inclination, and the bearing in the bearing assembly is inclined, causing the fan bearing to become hot during operation. The reason is that the installation and maintenance quality of the fan is not high, and the bearing works at the key edge where the angle can be adjusted.
2. This problem may occur if the quality of lubricating oil is poor, dust, sand, dust and other impurities, the filling capacity is insufficient, or the connecting bolts of bearing housing cover and valve seat are too tight or too tight.
3. The bearing housing is not filled with grease specified according to the standard. Usually, the logistics personnel are worried that the bearing will burn due to lack of oil in the fan, and excessive fuel will be added during refueling. At this time, the temperature will continue to rise to a certain point (usually about 10 to 15 ° C higher than the normal working temperature). Keep unchanged and gradually decrease.
4. The bearing is abnormal and heated. The installation deflection of the shaft and rolling bearings, the front and rear bearings are not concentric, and the damage to the fan rolling bearings or the bending of the shaft are all factors affecting the fan bearing temperature.
