2BV series stainless steel explosion proof water ring vacuum pump for industry
2BV series vacuum pump works basing on water ring principle, that is, impeller is installed eccentrically inside of pump body, after the pump start up, working liquid forms liquid ring(which is concentric with pump body ) inside of pump body, impeller passes motor power to liquid ring. Liquid ring pulse periodically between the impeller vanes, while in pulsation, gas is suctioned in through disk suction inlet and discharged from disk exhaust vent.

Problems and solutions:
| Appearance | Reasons | Solutions
|
| Motor does not start, no sound | Two power lines are broken | Check wiring
|
| Motor does not start, there is a buzz | One wire is broken, the rotor of the motor is blocked Impeller failure Motor bearing failure | Empty the cleaning pump if necessary to trim the impeller clearance Change Impeller Bearing change |
| When the motor is running, the current breaker runs | Winding short circuit Motor overload Exhaust pressure is too high Excessive working fluid | Check motor winding Reduce working fluid flow Reduce exhaust pressure Reduce working fluid |
| Over consumption | Precipitation
| Clean, remove the precipitate
|
| A pump does not create a vacuum | No working fluid System leakage is serious Wrong direction of rotation
| Check working fluid Repair the leak Replace the two wires to change the direction of rotation |
| Low vacuum | Pump too small Working fluid flow is too small Working fluid temperature is too high corrosion Systematic leak Seal leak | Use a larger pump Increase working fluid flow Cool the working fluid and increase the flow rate Replacement parts Repair the leak Check seal
|
| Sharp noise | Cavitation Working fluid flow is too high | Coupling gas erosion protection Check the working fluid and reduce the flow |
| pump leakage
| The seal ring | Check all sealing surfaces
