What is the difference between the time of the water before the start of the water ring vacuum pump unit?
The water supply of the water ring vacuum pump unit is divided into two types: external water supply and internal water supply. When the pumped gas may contaminate the working fluid in the pump, the external water supply seal is generally used in the selection, that is, the clean cooling water is introduced separately through the seal. Internal water supply refers to the use of working fluid in the pump for cooling. Generally, the internal water supply seal is often used when the gas suction is not complicated.

What's the difference between the time of the water before the start of the water ring vacuum pump unit?
1. Disadvantages of little or no water: If you use an internal water supply seal, then little or no water will cause the seal to burn out
2. The hazard of excessive water: Too much water in the pump at startup will cause excessive resistance at startup, which will cause the motor to burn or trip.
Matters needing attention when starting the water ring vacuum pump unit:
1. Ensure that the equipment is installed firmly and at a level
1. Disadvantages of little or no water: If you use an internal water supply seal, then little or no water will cause the seal to burn out
2. The hazard of excessive water: Too much water in the pump at startup will cause excessive resistance at startup, which will cause the motor to burn or trip.
Notes for starting the water ring vacuum pump:
1. Ensure that the equipment is installed firmly and on a horizontal surface
2. Ensure that the alignment of the motor and the pump meets the requirements
3. Check whether the bearing lubricant needs to be refilled
4. Manual turning to prevent the impeller from jamming and causing the motor to burn
5. Jog the motor to ensure that the motor rotates correctly
6. If the external water supply is sealed, first open the external water supply system
7. Supply water to the pump to reach the axis of the pump, and it cannot be filled up
