Deep well submersible pump pump before open, filled with liquid in the suction pipe and pump

Cut in the process of Wells with submersible electric pump device buried water pump no mud, and pump to bottom hole distance of not less than 3 m. Wells with submersible electric pump in use lift not too low, otherwise the device needs to be in the mouth of the well water pipe road gate at the additional traffic control channel operation, and avoid the heavy traffic and make the motor overload operation and burned. Pumps was proposed and the detection power supply before maintenance. Please users to device, motor overload maintenance, in order to ensure the normal operation of the motor, avoid burning motor. Wells with submersible electric pump in the condition of use, please users connected to ground zero, to prevent the leakage, the formation of human and animal damage. Upper with submersible motor shaft labyrinth sand control and two back to the installation of skeleton oil seal, avoid sand flow into the machine. Choose smooth bearing water submersible motor, bottom with a rubber membrane voltage regulator, pressure regulating spring, surge of control because of the pressure change with the temperature. Motor winding choose polyethylene insulation, nylon sets of water resistant electromagnetic wire, cable joint way according to the cable joint process. Deep well submersible pump pump before open, filled with liquid in the suction pipe and pump. After open pump, high-speed rotating impeller, the liquid with the rotating blades, in under the action of centrifugal force, fly away from the impeller to injection, injection of the liquid in the pump housing spread of indoor speed gradually slow down, the pressure gradually add, and then from the pump discharge, the discharge pipe. At the moment, in the blade because the liquid was dumped into the surrounding and form 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 so continually from the liquid pool was sucking up and continually from the discharge pipe flow. Electric pump before use, used to check the motor insulation resistance by megger are, its value can 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. Check the submersible cable has the phenomenon such as crack, scratch, if there are any damage should be timely exchange, in case of leakage. Should open irrigation water motor bolts, filled with clean water after tightening bolts, into the water again. Oil motor oil is found, should be replaced after packing element into the water again. Before the electric pump into the water, should be to pump water infusion in qing dynasty, idling 1 - 2 seconds, and 2 times, look at idling and launch is normal. If turned to the contrary, the two-phase wiring after swap. See Yang pipe crack, connection is strong. Pumps in submerged or lift, shall not pull the cable and avoid cable damage or disconnect joint. Supply voltage should be manipulated without greater than or less than 5 additional voltage range, if the voltage is too high or too low will damage motor.
