Submersible pump instructions

Submersible pumps are working underwater. It is compact, light weight, not long from the shaft pumping shaft. Therefore, the submersible pump is well suited to rural well water irrigation. Application is more QS submersible pump. This submersible pump, is the use of mechanical seals or seals and other waterproof measures to keep the motor inside dry, from water intrusion. Use should pay attention to the following points: (1) Check the pump vent, drain hole, drain hole and the cable connector seal is loose, if loose must be tightened. (2) Inspect the insulation resistance with a 500-volt shake table, and should not be less than 0.5 megohms. If it is lower than this value, open the drain and bleed holes and dry or dry it. (3) Check the cable, if broken or broken, etc., should be replaced, so as to avoid leakage. (4) before starting to check all the circuits, switches, to see if the wiring is correct and solid. Then, turn on the ground for 3 to 5 minutes (time should not be too long, so as not to damage the parts or burn the motor windings), and check the motor rotation direction is correct, as above, no problem, can be put into the water to use. (5) submersible pump into the water, the cable must not be forced, the rope should be tied to it in the wellhead wooden frame. The maximum depth of electric pump into the water is 3 meters, the minimum depth of 0.5 meters (from the center of the impeller). (6) In operation, the change of water level in well should be observed frequently. The motor must not be exposed to the water, nor into the mud, so as not to affect the motor heat and burn the winding. Should change with the well water level, at any time lift the pump, such as the emergence of water reduction or interruption, should immediately identify the cause or shutdown inspection. The cable can not be friction with the well wall, so as to prevent the well from penetrating into the motor along the cable core after the cable is broken. (7) A new or replaced submersible pump with integrated seal box shall be inspected for a good seal after 50 hours of use and shall be inspected once a month thereafter. Also, check that the shielding sleeve seal between the motor rotor and the stator is good. (8) After one year of use, check the corrosion of the pump and remove rust paint. Submersible pumps such as long-term use should be carefully inspected on a dry and ventilated house custody.
