Noise-free motor for cooling tower

Maintenance of cooling tower motor not rotating

The main reasons for the cooling tower fan motor not rotating are: winding open circuit, lack of oil to hold the shaft, abnormal capacitor, etc. From the maintenance practice of electric fans, the latter two faults are mostly. For non-rotating electric fans, my maintenance steps are to measure the plug, rotate the motor, measure the capacitance, and then process it. The first step is to measure the operation of the electric fan and the speed regulating winding. Rotate the electric fan timer first. When you hear a click, the timer is normal. If there is no click, the timer is damaged. If there is no resistance value, it may be that the motor windings have been burnt and broken. For a motor with a thermal fuse, the thermal fuse may be an open circuit. You should also disassemble the motor and take a look. If it is only an open circuit, short the thermal fuse to return to normal. The gear switches are all damaged, but the possibility is unlikely. The second step is to check whether it is holding the shaft, remove the electric fan guard, and rotate the motor shaft by hand. If it does not turn, it means that the motor is holding the shaft seriously. Disassemble the motor, first remove the oil and rust on the front and rear bushings and the motor shaft, and then add enough sewing machine oil to the linoleum of the front and rear bushings. Most electric fans can be trouble-free. The third step is to measure the starting capacitance. If the motor shaft rotates flexibly, the starting capacitance of the electric fan motor must be measured. First, use a multimeter to measure the R×100Ω range of the motor starting capacitor, and measure the resistance value of the entire electric fan motor running, starting and speed regulation windings, that is, the resistance value of the black and ** leads. Maintenance of active electric fans For electric fans with active motors, I will do it in one step based on the actual situation. Rather than carrying out maintenance step by step as described above. If the user says, the electric fan rotates slowly first, and then gradually becomes faster. According to experience, the motor is generally holding the shaft slightly. The reason is the initial lack of lubricant for electric fans. Directly disassemble the electric fan motor, add enough sewing machine oil to the linoleum of the front and rear bushings, and it can usually be repaired. Remote control electric fan, turn on the power to eliminate the fault. The current remote control fan control actuators are basically SCRs. It can be seen from the principle that the thyristor is essentially equivalent to the switch thyristor breakdown is equivalent to the switch being turned on. Of course the electric fan will turn when the power is turned on. For example, when a floor-standing remote control electric fan is in use, the remote control functions are basically normal, but the electric fan is not unplugged after the electric fan is turned off. The electric fan has an obvious vibration feeling and the electric fan makes a buzzing sound, especially at night. Look at the electric fan blades. It is also turning slowly. Because the control functions are basically normal, the MCU is normal, and it can be seen from the above principles that the SCR is faulty.

Cooling tower motor has long service life and no noise

The cooling tower motor is modified in various aspects on the basis of the original cooling tower. For example, a modification such as a water turbine to replace the original fan motor is a very wise modification. This makes the cooling tower motor we use now can With such a good use effect, the cooling tower has been an obvious improvement from the past to the present. The cooling tower motor has the following characteristics: 1. Energy saving: the cooling tower uses a water turbine to replace the fan motor, which completely saves the fan motor. The running power consumption does not increase the running current of the circulating water pump, which saves the user a huge amount of electricity bills. 2. No noise: The energy conversion of the water turbine is completed in the water channel, and the motor and reducer are eliminated, the low-frequency electromagnetic sound is eliminated and the mechanical noise is greatly reduced. 3. High efficiency: the turbine shaft directly drives the fan, no need to pass through other reducers, etc., and the air volume changes correspondingly with the change of the water flow, which is always stable at a better air-water ratio to ensure the heat dissipation effect. 4. Long service life: The hydraulic turbine has simple structure, mature and feasible technology, and the overall designed working life is more than 15 years. The turbine shell is a mixed structure of casting and welding. The welded steel plate is a special steel plate for imported boilers with a manganese content of 3.5%. It is not easy to rust after long-term use. The impeller is precision cast and is annealed to eliminate stress before balance adjustment.
