Water ring vacuum pump failure - maintenance

Water ring vacuum pump is what?

produce water ring spin centrifugal force effect, in order to obtain the water ring vacuum pump vacuum. Mainly used for inhalation of air, high vacuum degree can reach more than 85%. It is composed of pump body and pump cover. The distribution of the impeller by evenly radiated multiple blade and hub. Before start the pump to the studio work into the right amount of water or other fluid. Starts, due to the effect of centrifugal force, water being thrown into the studio walls, form a rotating water ring.

water ring pump has the following advantages:

( 1) Simple structure, manufacturing precision is not high, easy to processing. The operation is simple, easy to maintain.

( 2) Compact structure, general directly connected to the motor pump, high revolutions. Adopt the structure of the small size, large displacement can be obtained.

( 3) No metal friction pump cavity surface, no lubrication pump. Seal between rotating part and fixed part can be done directly through the water seal.

( 4) cavity compressed gas temperature change is small, can be thought of as isothermal compression, so it can remove inflammable and explosive gas.

( 5) Because there is no exhaust doors and friction surface, so it can remove dust, gas condensable gas and water mixture.

water ring water pump has the following disadvantages:

( 1) Low efficiency, usually about 30%, the best is 50%.

( 2) The vacuum degree is low. This is not only due to the structure limits, and more importantly, working fluid saturation vapor pressure.

water ring vacuum pump is disassembled should pay attention to?

( 1) Take out stitches told Electric, power, and put a warning card 'if someone is maintenance, please do not move'.

( 2) Water ring vacuum pump on the pipe connected to the system disconnected or add blank plate.

( 3) Remove the water ring vacuum pump before, should first through the scupper draw off the water ring water pump.

( 4) Removing water ring vacuum pump, carefully remove all gasket. If damaged, please use the same material and same thickness change new gasket.

( 5) Water ring vacuum pumps should never close to one end of the motor disassembly. The reverse order of disassembly sequence and installation.

water ring vacuum pump troubleshooting

1, adjust the production process

add water box at the entrance of water ring vacuum pump, reduce the oil and gas and solvent into the pump body, and prevent the vacuum pump cylinder and valve plate of coking due to tight and heating.

2, above the water ring vacuum pump inlet pipe to add a beam, between the beam and the inlet pipe to add a spring hanger, adjust the spring hanger, mention pipeline, vacuum pump cylinder pressure and processing, 02016, the motor is in working condition.

3, add torrent ring pump discharge pipeline ensure vacuum water pump exhaust pipe diameter.

4, from the beginning to adjust the base of the water ring vacuum pumps

to ensure the basic level and stable. Through the above processing, water ring vacuum pump motor overheating problem has been solved.
