The reason why the water ring vacuum pump automatically trips during use

The appearance of the water ring vacuum pump automatically tripping during use often causes headaches! So how to solve the failure of the water ring vacuum pump trip? First, we need to understand the cause of the trip and then analyze it to solve the fault of the water ring vacuum pump trip. The reason for this is that the water ring vacuum pump automatically trips as long as there are three major situations:

1. The motor of the water ring vacuum pump is overloaded.

When the water ring vacuum pump motor is overloaded, the water ring vacuum pump will automatically trip for protection because the current through the motor is too high and exceeds the current set by the water ring vacuum pump electric control box or the relay protector. The tripping phenomenon at this time is normal. But we need to consider the magnitude of the motor's rated current. It is necessary to find out the cause of the motor overload to solve the problem of overload operation of the water ring vacuum pump motor.

The basic inspection items are as follows:

1. Is there any foreign matter entering the pump cavity of the water ring vacuum pump;

2. Whether the flow rate of the working fluid of the water ring vacuum pump is too large, whether it needs to be adjusted;

3. Whether the pressure of the water ring vacuum pump exhaust port is too large;

4. Whether the water ring vacuum pump exhaust pipe is blocked;

5. Is the water ring vacuum pump exhaust pipe installed too high or too thin?

Second, whether the water ring vacuum pump is deactivated for a long time.

The water ring vacuum pump is deactivated for a long time, and the motor load will cause the temporary current to be too high.

After the water ring vacuum pump is deactivated for a long time, you should try to rotate the shaft and the impeller before starting the machine to see if it can rotate normally, and check if foreign matter is transferred into the pump chamber. At the same time, a rust remover or 15% oxalic acid can be added for about half an hour to remove scale.

3. The water ring vacuum pump motor is connected to the two-phase power supply, and the three-phase power supply is not enabled.

At this point, the three-phase power of the water ring vacuum pump can be turned on. Before starting the machine, you should carefully check the specifications and models of the water ring vacuum pump, the rated power of the motor, the rated voltage, and the rated current. The operating instructions must be strictly installed for proper operation.

Permanent magnet variable frequency screw compressors can maintain high output efficiency at low rotate speed. The greater the fluctuation of air volume in the system, the more obvious energy saving effect is. LGM series permanent magnet frequency conversion screw air compressors adopt permanent magnet (IPM) motor with huge energy saving efficiency and superior performance. When used with dedicated servo drivers together, they will give full play to the incomparably energy-saving effect than general induction motors. According to the exhaust temperature, cooling fan with variable frequency control can control the fan rotate speed to prevent power waste, reduce noise and stabilize the system. Through wide range control, the maximum amount of air displacement is increased by about 16%.
