The influence of pump inversion
The influence of pump inversion
64. How to deal with screw pump inversion after bar stopping
Answer: When finding reversal, shut off the outlet valve of the pump and check the electric power carefully.
Machine, pump bearing temperature and mechanical seal diaphragm pump leakage, if no abnormal situation can be done well
Prepare to start the pump next time.
65. What is the effect of reverse gear pump rotation on beam occurrence 7
Moss: The following problems may occur when the centrifugal pump reverses:
(1) Because of the high impulse when reversing, the tight solid of the threaded connection is loosened.
It will cause damage to rotor parts.
(2) Because of the loss of resistance in the pump, the temperature of the pump body will rise.
(3) Because the oil supply force of bearing bush is fixed, the reverse clock Bush is pressurized.
The surface lubrication condition deteriorated and the bearing bush was easy to burn.
66. When the weeping water elephant is in normal operation, the electric shear suddenly rises and the discharge volume increases.
What are the causes of human beings? How should we deal with them?
Moss: (1) Reasons: (1) Pump outlet pipeline or dedicated to water trunk perforation
Rupture; Pumping stops at other water stations connected to the water injection network.
(2) Processing methods: (1) timely control of the discharge of the injection pump at the mouth of the mountain
Motivation overload: 2. Reporting and dispatching.
67. Whatever should be put into the spare weeping pump in winter?
Each section of the inlet pipeline of Gangwei water injection pump is outdoors, not in the net pipeline.
When the temperature is low in winter, the stored water will cause the pipeline to freeze or burst. Emptying
The purpose is to freeze the rib L pipeline.
