Motor casing is the main part of the motor of the electric submersible pump, its machining accuracy directly affects the quality of the electric submersible pump. Due to than buckle hole turning process motor shell large radius thickness than easy to produce elliptical deformation, deformation is generally 0.03-0.10mm, can not meet the user's requirements, if this problem is not solved, will lead to huge economic losses to produce qualified products.
Motor casing is the main part of the motor of the electric submersible pump, its machining accuracy directly affects the quality of the electric submersible pump.

In the cutting process, the thermal deformation of the workpiece is mainly used by the cutting heat for turning, although a large number of cutting heat was small, but there are still 30% of the cutting heat to the workpiece, the workpiece in the processing of thermal expansion to the contraction of the cooling in the smaller, even in the poor thus making the thermal deformation of the workpiece is to affect the machining accuracy of the workpiece can not be ignored as an important factor.
To reduce the main measures of thermal deformation is to reduce the cutting heat, and reduce the cutting heat from the machining process, cutting and cutting tool geometry parameters of the reasonable choice of separation, and give in sufficient cooling.
Motor shell charged causes.
I. The cause of the fault may be.
1 )The motor winding is damp or the insulation is severely aged.
2 )Poor grounding.
3 )Wrong power cord and grounding wire.
4) Serious dirt on the terminal board.
5 )The insulation of the lead wire is aging and broken.
6 ) Winding end of the top cover grounding.
Second, the corresponding treatment methods are.
1 ) moisture motor drying treatment; aging insulation must be updated in a timely manner.
2 ) along the grounding line to find out the cause, take appropriate measures to correct.
3 )Find out the power cord and grounding wire to correct the wiring error.
4 )Clean the terminal board.
5 ) Wrap or renew the lead | out of the wire with insulating tape.
6) Remove the end cover, find out the grounding point, coil grounding point should be wrapped insulation and paint treatment, end cover wall should be lined with insulating paper.
