The problem of the high temperature of the vacuum pump has been perplexing the users. The long time in the high temperature can greatly shorten the life of the vacuum pump. Today we are going to do some research to see what causes the high temperature of the vacuum pump and how to solve these reasons.
An antidote against the disease disease effectively solve the high temperature problem of vacuum pump
The problem of the high temperature of the vacuum pump has been plaguing the vast number of users, so how can the vacuum pump be allowed to avoid high temperature so as to prolong the service life?
We have studied the problem, and today we bring a few points to the vacuum pump for the summer.
The cause of the disease is:
1. motor power is too large, the working current is too large, the vacuum pump will increase the temperature.
2. the number of fan blades is not enough, there is not enough air volume, which causes the temperature of the vacuum pump to rise.
3. fan speed is too low, wind pressure, wind power is insufficient.
4., the bus voltage of the vacuum pump motor is 380V. Because the cable voltage drop and load distribution are uneven, the actual voltage added to the motor is only 365V, and the voltage is low, resulting in a large running current.
There are too many dust in the 5. motor, and oil stains and stains are also one of the factors that cause the temperature of the vacuum pump to increase.
An antidote against the disease：
The motor power and speed are matched with the vacuum pump, which can not be changed. The fan is installed on the spindle of the motor. The speed of the motor is determined by the speed of the motor, and it can not be replaced. Although increasing the number of fan blades can play a certain role, the dynamic balance is not easy to find after increasing the number of blades. If the alignment is not good, it will cause the motor vibration to increase.
1., the original vacuum pump fan hood is lengthened 40cm, and an axial flow fan with the same diameter of the fan cover is added to it. The axial fan motor power is 850W, the speed is 1489r/min, and the voltage is 380V. The original fan continues to be retained. The axial fan has another power control, and the axial fan is not connected with the main motor. After the vacuum pump is started, the axial flow fan is started in time. After the vacuum pump is stopped, the 30min is stopped by the axial fan to make the main motor fully cooled.
2. clean the dust on the motor of the vacuum pump regularly, keep the motor radiator clean, and increase its heat dissipation capacity.
3. the voltage of the busbar of the vacuum pump is adjusted to 400V.
As the medicine took effect, the symptoms lessened：
1., because the speed of axial fan is high and the air pressure and air volume are large, the cooling effect is greatly enhanced. Under the same ambient temperature and load current, the temperature of the main motor of the vacuum pump has decreased by 12 degrees. The temperature of the main motor in summer is not beyond the limit.
2. slow down the aging speed of the main motor and prolong its service life.
The 3. shaft fan can be controlled artificially. After the main motor is stopped, the axial fan can still run, which can make the main motor fully cooled.
When the 4. voltage is adjusted, the current of the diaphragm pump is reduced to 210A, and the calorific value is relatively reduced. Wine pump
5. to balance the load distribution of 2 sections of busbar as far as possible to prevent a certain section of the bus from overloading due to excessive load.
Through the study of the high temperature problem of vacuum pump, we find that the high temperature of vacuum pump is mainly caused by the heating of motor, so the main way to solve the problem is around the development of vacuum pump motor.
