Abstract
The utility model relates to an empty water-cooling heat screen structure for a high temperature high pressure shield electric pump. The empty water-cooling heat screen structure for the high temperature high pressure shield electric pump comprises a stator, a first cover plate, a second cover plate, a stud, a base body, a circular hole and an inclined hole. The first cover plate and the second cover plate are connected with the base body in a welded mode and installed on the stator through the stud, the circular hole is arranged in the first cover plate and the inclined hole is arranged in the base body. The empty water-cooling heat screen structure for the high temperature high pressure shield electric pump has the advantages of being simple in structure, reasonable in design, and capable of reducing heat transmitted from a pump to a motor, increasing heat insulating capability, reducing use of raw materials and the axial size of a pump assembly and improving reliability of high temperature and high pressure shield electric pump due to the fact that the empty water-cooling heat screen structure is adopted.
Description
Technical field: the utility model relates to a kind of High Temperature High Pressure shielded electric-pump air water cooling heat screen structure.
Background technique: at present, the cold and hot screen that the High Temperature High Pressure shielded electric-pump is used adopts the air cooling heat shielding mostly, medium temperature can satisfy usage requirement in time below 300 ℃, when medium temperature surpasses 300 ℃, the heat shielding structure is strengthened, cause material to increase and the axial dimension of pump assembly increases, cause structural instability.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned shortcoming, a kind of High Temperature High Pressure shielded electric-pump air water cooling heat screen structure is provided, the cold and hot screen that it has mainly solved the High Temperature High Pressure shielded electric-pump adopts the air cooling heat shielding mostly, when medium temperature surpasses 300 ℃, the heat shielding structure strengthens, cause material to increase and the axial dimension of pump assembly increases the problems such as structural instability.The purpose of this utility model be achieved in that the High Temperature High Pressure shielded electric-pump with air water cooling heat screen structure by: stator, the first cover plate, the second cover plate, stud bolt, matrix, circular hole, inclined hole consist of.The first cover plate, the second bridge welding are connected on the matrix, and are installed on the stator by stud bolt, and the first cover plate is provided with circular hole, and matrix is provided with inclined hole.This product structure is simple, and is reasonable in design, and it adopts air water cooling heat shielding structure, can reduce the heat that is transmitted to motor from the pump end, has strengthened heat-insulating capability, has reduced the axial dimension of raw-material use and pump assembly, has improved the reliability of High Temperature High Pressure shielded electric-pump.
