Deep well submersible pump price

Deep well submersible pump prices, the preferred deep-well submersible pump factory.
    Before opening the pump, the suction pipe and pump must be filled with liquid. After the pump is pumped, the impeller rotates at high speed, and the liquid rotates with the blade. Under the action of centrifugal force, it leaves the impeller outward and the liquid is gradually slowed down and the pressure gradually increases from the pump Outlet, discharge pipe out. At this point, at the center of the blade at the center of the liquid is thrown to the surrounding and the formation of both no air and no liquid vacuum low pressure area, liquid pool in the pool of atmospheric pressure under the action of the suction pipe into the pump, the liquid is so continuous Constantly being sucked up from the liquid pool and continuously flowing out of the discharge pipe.
    1. Pump before use, the application of megger check motor insulation resistance, the minimum value of not less than 5 megohm. Inspection method is a megger on the table connected to a pump on the cable line, the other terminal connected to the motor shell, shaking megger to observe the insulation resistance.
    2. Check the diving cable to crack, scratches and other phenomena, if damaged should be timely exchange, to prevent leakage.
    3. Water immersion motor should open the irrigation bolts, filled with clean water after the tightening bolts, and then dive into the water. Oil-immersed motor, such as oil spills, should replace the sealing element and then sneak into the water.
    4. Pump into the water before the pump should be filled with water, idle 1-2 seconds, and start 2 times, check the idling and start is normal. If the reverse, the two-phase wiring can be replaced.
    5. Check whether the water pipe cracks, the connection is solid.
    6. When the pump is submerged in water or lifted, do not pull the cable to avoid damage to the cable or disconnect the connector.
    7. The supply voltage should be within 5% of the rated voltage. If the voltage is too high or too low, it will damage the motor.
    8. Pump submerged into the water should be vertical, not tilted.
    9. Pumps may not transport more water or mud with more sediment. Flooding motor should always clean the sand inside the motor cavity, the replacement of motor cavity water.
    10. The actual pump head should be within 0.8-1 times the rated head. This can improve the efficiency of the pump, saving, to avoid motor overload operation, to extend the service life.
    11. After the pump is used, it should be cleaned, rust-proof on the metal surface, and stored in a dry place. The submerged motor should also be placed in the motor.
