Water ring vacuum pump drive pump operation - right

water ring vacuum pumps should be pumping before normal use. Only can use pump makes the machine work normally. When using, must master certain skills before starting the pump operation. Smooth smooth, here a brief introduction to water ring vacuum pump drive pump operation right.

。

a, preparation, water ring vacuum pump

1, confirm installed at the entrance of pump pressure gauge, and export the pressure gauge on the separator. The use of vacuum gauge and pressure gauge, and on the steam separator used pneumatic automatic filling water and drain valve and liquid level gauge. Close the steam separator at the bottom of the exhaust valve; Please contact the electrician and fitter, in order to ensure consistency of the steering pump and steering of the motor. Confirm the tool ( Wrench, auscultation, rags, oil pot) Is complete, and confirm that the pump has been correctly grounding and confirm it. pump fixed bolt looseness, and use of the cooler cooling water to ensure a smooth return. Slowly open the pump outlet valve to open up a third of the valve position, turn the car, check whether the flange leakage.

2, the water injection pump type belongs to the closed loop system. Supplement water system through steam separator of water injection water pump body again. Open pump, open the steam separator water injection valve to fill the pump body. When at the bottom of the pump to see three after discharge the water in the plug, plug screw on emissions and close the steam separator water injection valve to stop the filling pump body, make the water in the pump just above the drain plug.

2, water ring vacuum pump running

1, the valve closed tracheal path, open the gate valve of water supply, and supply water to the water ring vacuum pump. When the liquid flows out of automatic drain valve, closing the entrance gate valve and open the motor.

2, open the inlet valve.

3, when the automatic drain valve without the water out, start the motor, and then running water ring vacuum pump. At the same time, open water gate, to fill the vacuum pressure gauge pointer is close to 0 mpa ( No vacuum gauge pressure for) 。 When the water ring vacuum pump suction absolute pressure drop, pointer will be moved to a negative value ( Reading between 0 and - 0. 003 MPa) ( Creates a vacuum) 。

4, if gas is flammable, explosive, toxic or to recycle gas, please adjust the sealing liquid level of circular gas water separator, the liquid level in the middle of the liquid level meter, in order to prevent the gas. Leaks. Three, adjustment

1, confirmed after start-up and adjustment, confirm the pump flow and pressure of the normal and stable, the vibration of the pump is normal, and confirm the bearing box of external temperature does not exceed 70 ° C, make sure no leak, cooling water temperature and pressure is normal, and confirm the motor current. Normally, motor vibration noise is normal.

water ring vacuum pump operation is roughly as described above. I hope everyone can master it. The operation of the machine not only pay attention to the daily maintenance and maintenance work, but also pay attention to the operation of the pump. Better use of the machine, the site will be updated from time to time, knowledge content, hope you like them. Please contact the service personnel are not familiar with.
