Who is the trouble of 2BV vacuum pump | Who is 2BV vacuum pump or the possible cause of failure | Who is 2BV or vacuum pump to eliminate the reason |
The motor does not start and there is no sound | ||
The motor does not start, there is a buzzing sound | 1.One wiring is broken and the motor rotor is locked. 2. Impeller failure. 3.Motor bearing failure | 1.Drain clean pump if necessary and correct impeller clearance. 2.Change impeller. 3.Replace the bearing |
When the motor starts, the current circuit breaker trips | 1. The winding is short circuited. 2. Motor overload. 3. The exhaust pressure is too high. 4. Too much working fluid | 1. Check the motor winding. 2. Reduce the flow rate of working fluid. 3. Reduce the exhaust pressure. 4. Reduce the working fluid |
Excessive power consumption | Precipitation is produced | Clean and remove sediment |
1. No working fluid 2. Serious system leakage 3. The rotation direction is wrong | 1 check the working fluid 2. Repair the leak 3. Change two wires to change the direction of rotation | |
1. The pump is too small 2. The flow rate of working fluid is too small 3. The working fluid temperature is too high (less than 15 ℃) 4. Corrosion 5. Slight system leakage 6. Seal leakage | 1. Use a larger pump 2. Increase the flow rate of working fluid 3. Cool the working fluid and increase the flow rate 4. Replace parts 5. Repair the leak 6. Check the seal | |
1. Cavitation 2. The flow rate of working fluid is too high | 1. Connect the gas shield 2. Check the working fluid and reduce the flow rate | |
leakage | The sealing gasket is damaged | Check all sealing surfaces |
