Deep well pump assembly should meet the following requirements

First, the assembly of pumps, water pipes, shaft, the connection should be tightened gradually into the well, to prevent the pieces and tools fall into the well, submersible pump cable should be tied to the water pipe;
Second, the threaded connection of the water pipe connected to each other, should be added oil, should not be filled with linen, lead oil; tube end surface should be fitted with bearing bracket (long shaft deep well pump) or direct fit, The depth of the tube should be equal; flange connection of the water pipe, the flange face should be added between the gasket;
Third. If the well pipe is slightly skewed, the pump seat should be correspondingly skewed (do not simply correct the level of the pump seat); the gap between the pump base and the foundation should be Wedge iron filling.
Fourth, the long axis of deep well pump should still meet the following requirements:
1. When the drive shafts are connected with each other, the two shaft end faces shall be fitted together, and the depths of the shafts screwed into the couplings shall be equal;
2. Motor and pump seat should be close fit, during which no padding, such as the motor shaft and the motor shaft is not the same axis, should be in the pump seat and the base of the ramp plus horn adjustment.
Fifth, deep well Submersible pump should still meet the following requirements:
1. Pump and motor assembly, the motor should be filled with water to the submerged motor filled with clean water;
2. The depth of the unit into the water should not exceed 70 meters, such as must be more than 70 meters, should the motor stator windings, cables and fittings for water pressure test.
