The motor shell is the main part of electric submersible pump motor, the machining precision directly influences the quality of electric submersible pump. Compared with the large radius of motor shell hole turning process is easy to produce the thickness ratio of the elliptical deformation, the deformation is generally 0.03-0.10mm, can not meet the requirements of users, if this problem is not solved, it will cause the enormous economic losses to the production of qualified products, through the deformation processing of electric submersible pump motor shell in the turning process, after a detailed analysis of Daqing pump market share stable motor housing, put forward a feasible solution.

创盈购彩welcomeIn the cutting process, the thermal deformation of the workpiece is mainly composed of cutting heat for turning, although a large number of cutting heat is small, but there are still 30% of the cutting heat to the workpiece, the workpiece in the processing of thermal expansion in the cooling shrinkage of small, even in the poor so that the thermal deformation of the workpiece is affecting machining accuracy of workpiece the important factors can not be ignored.

创盈购彩welcomeIn order to reduce the thermal deformation of the main measures is to reduce the cutting heat, and reduce the cutting heat from the machining process, cutting and cutting tools to select a reasonable separation of geometric parameters, and given sufficient cooling.

创盈购彩welcomeMotor shell charged reason

创盈购彩welcomeFirst, the cause of the failure may be:

1) the motor winding is severely damaged by damp or insulation;

创盈购彩welcome2) bad grounding;

创盈购彩welcome3) power line and grounding wire is wrong;

4) wiring board serious dirt;

5) lead wire insulation aging damage;

创盈购彩welcome6) winding end top cover ground.

创盈购彩welcomeTwo, the corresponding treatment methods are:

创盈购彩welcome1) to damp the motor drying treatment; aging insulation must be updated in time.

2) to find out the cause of the grounding line, take appropriate measures to correct.

创盈购彩welcome3) to find out the power cord and grounding wire after the correct wiring error.

创盈购彩welcome4) to clean the wiring board.

创盈购彩welcome5. Use insulation tape to wrap or update the leads.

6) remove the lower cover, find out the place, the coil to the site of the insulation and paint treatment, the end of the cover must be insulated with paper liner.
