Working principle of deep well submersible water pumps

Deep well submersible pump motor and pump water machine straight league one into the water, it has a simple structure, for its high efficiency, low noise, safe and reliable operation, the advantages of easy installation and maintenance.

It is suitable for the deep well, hot well and Marine extract, can also be used in rivers, reservoirs, canals and other extraction: mainly used for farmland irrigation and plateau mountainous area with water, can also cities, factories, railways, mines, construction site water supply and drainage.

Open pump, the suction pipe and pump must be filled with liquid. After open pump, high-speed rotating impeller, the liquid with the blades rotate together, in under the action of centrifugal force, fly away from the impeller to injection, injection of the liquid in the pump shell gradually spread of indoor speed slow, pressure increase gradually, and then from the pump discharge, the discharge pipe flow.

At this point, in the center of the blade due to liquid was dumped into the surrounding formation is no air and no liquid vacuum low pressure area, fluid in the pool liquid under the action of atmospheric pressure on surface of the pool, the suction pipe into the pump, the liquid is continuously from the liquid pool was sucking up and continuously from the discharge pipe flow.1. Electric pump before use, application, check the motor insulation resistance by megger are the lowest not less than 5 ohms. Check method is to connect a terminal on the megger on electric pump cables, another terminal on the motor shell, shaking megohmmeter, observe the insulation resistance.2. Check the submersible cable have the phenomenon such as crack, scratch, if there are any damage should be timely exchange, in case of leakage.3. Should be open irrigation water motor bolts, filled with clean water after tightening bolts, into the water again. Oil motor oil is found, a packing element should be replaced for the dive.

Before the 4. Electric pump into the water, should be to pump water infusion in qing dynasty, idling 1 to 2 seconds, and start the 2 times, check normal idling and start-up.If turned to the contrary, the two-phase wiring after changing.5. Check the lift pipe crack, connection is firm.6. Pumps while diving or lift cannot pull the cable, so as to avoid cable damage or disconnect joint.7. The power supply voltage should be controlled in not greater than or less than 5% of the rated voltage range, if the voltage is too high or too low will damage motor.8. Electric pump into the water should be vertical, not sideways.9. More water or mud pumps shall not transport sediment concentration.

Water motor should always clean up cavity of the sand, the change of water motor cavity.10. The actual pump head should be within 0.8 1 times the rated head. Which can increase work efficiency of pumps, power-saving, to avoid electrical overload operation, to extend the service life.11. Electric pump after use, should be clean, besmear antirust oil in metal surface, and the vertical in a dry place. Water motor should also put a net in the water.
