2BV series liquid ring type vacuum pump for plastic machine milking machine

 

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.

 

  • The close-coupled design is convenient to install and can save space.
  • The bearings are all used the imported products with brand name of NTN or NSK
  • The standard seals are all used the John Crane mechanical seals, eliminating leakage, easy maintenance
  • 2BV series products have the cavitation protection port. When they work under the condition near the limited vacuum, the cavitation protect port opens (or connects with the separator)to get rid of the screaming to protect the pump.
  • Aluminum bronze impeller is of high intensity and wearing well. The erosive-proof capacity of the pump can be improved by using it. If the parts where the liquid flows are made of the stainless steel,the pumps can be used under the more rigorous condition.
  • The unique design of the discharge port can protect the pump from the over-pressure to ensure the best efficient performance in the working range of the 2BV vacuum pump.
  • The motors are all adopted Y2 series products. The protection class is IP54 or IP55 (normal is IP44) and the insulation grade is F.(normal is B).
  • 2BVwater ring vacuum pump can achieve all of the PTFE flexible seal, which can greatly extend the working life in more demanding conditions
  • Running smoothly, the noise can be as low as 62 db.

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
