QS small submersible pump installation using technical support

1, after the box check QS small submersible pump nameplate model specifications are consistent with the actual use.
2, select the connection with the small submersible pump caliber to match the pipe, and then tighten the hoop.
3, choose to use the power supply voltage of 380 ± 5% volts, the power frequency should be 50 Hz.
4, with 500 V megger, measuring winding on the chassis insulation resistance of not less than 150MΩ.
5, such as the use of small submersible pumps from the power source far away (generally should not exceed 200 meters), in order to ensure QS small submersible pump pressure drop fluctuations are not too large, please refer to the table recommended by the power cable Corresponding bold, and its joints are applied with solder paste. After welding with insulating waterproof bandage (prohibited in the submersible pump water level below the wiring).
6, shall not be discharged mud, dung, sewage, dirt and other corrosive media.
7, before using the screw screw and deflated screw, the motor cavity should be filled with clean water, tighten the water screw can be used before the water.
8, QS small submersible pump in the operation may not be dehydrated operation (recommended installation of automatic water level controller) to always observe the voltage, current and pump flow, should ensure that the pump running under rated conditions.
9, QS small submersible pump in the winter when the suspension should be exhausted in the machine filled with water to prevent cracking. Placed in a place where the ventilation is dry and non-corrosive. Apply the screwdriver into the impeller once every time to prevent the pump from being embroidered
