Disassembly Steps for Common Wear Parts of 2BV Liquid Ring Vacuum Pump

I. Disassembly Steps for 2BV Liquid Ring Vacuum Pump Mechanical Seal

The mechanical seal of a 2BV liquid ring vacuum pump is one of the parts that wears out easily. During long-term operation, if water leakage, air leakage, or seal surface wear occurs, the mechanical seal should be replaced in time. Otherwise, it may affect the normal working efficiency of the vacuum pump. Let’s take a look at the disassembly steps for the mechanical seal of a 2BV liquid ring vacuum pump.

1. First, stop the 2BV liquid ring vacuum pump and disconnect the power supply.　　

2. Shut off the water supply system and drain the remaining liquid inside the pump body.　　

3. Remove the coupling guard and related fixing screws.　　

4. Slowly remove the old mechanical seal assembly.　　

5. Check whether there is wear or debris on the shaft sleeve and sealing position, and clean them.　　

6. Replace with a new mechanical seal and confirm the installation direction is correct.　　

7. Reinstall the coupling guard and tighten the fixing screws.　　

8. Start the equipment for trial operation and check for leakage to complete the replacement.　　

II. Disassembly Steps for 2BV Liquid Ring Vacuum Pump Impeller

The impeller of a 2BV liquid ring vacuum pump is also an important wear part during operation. If corrosion, wear, or deformation occurs after long-term use, it may lead to reduced vacuum degree and increased operating noise. Therefore, regular inspection of the impeller condition is very important. Let’s take a look at the disassembly steps for the 2BV liquid ring vacuum pump impeller.

1. First, ensure that the 2BV liquid ring vacuum pump is shut down and powered off.　　

2. Shut off the working liquid system and drain the liquid inside the pump body completely.　　

3. Remove the fixing bolts on the pump end cover.　　

4. Slowly open the pump cover and remove the old impeller.　　

5. Check whether there is scale, rust, or debris inside the pump chamber and clean it.　　

6. Replace with a new impeller and confirm the installation position is correct.　　

7. Reinstall the pump cover and evenly tighten the fixing bolts.　　

8. Restore the water supply system and conduct a trial operation to check whether the equipment is operating normally, completing the replacement.
