Abstract
The utility model relates to the product field of a fluid delivery pump, in particular to a high temperature and high-pressure shielding motor applicable to high temperature superpressure ultra-low flow delivery of media containing grains without leakage. The high temperature and high voltage shielded motor comprises a stator case, a stator, a rotor and an antifriction bearing. Lubricating oil is filled in the cavity between the stator and the rotor. The high temperature and high voltage shielding motor is characterized in that a cooling cavity is arranged on the stator case; and lubricating oil is filled in the cooling cavity. The high temperature and high voltage shielding motor has the advantages that the high-pressure load of liquid inside is transferred to the stator case through the special stator; auxiliary impellers on the rotor drive the lubricating oil between the rotor and the stator to circulate, thus taking away the heat of the rotor and the stator; a cooling coil on the stator case achieves the heat exchange between the lubricating oil and the cooling cavity, thus ensuring the temperature of the rotor and the stator within the allowed and ensuring the motor to drive a pump stably and reliably. The motor provided by the utility model can work reliably under high pressure and high temperature.
Description
[technical field]
The utility model relates to liquid delivery pump series products field, is specifically related to a kind ofly be applicable to high temperature, superhigh pressure, extra small flow, contain particle, requires medium not have and leaks the high temperature high voltage resistant shield electric machine of carrying.
[background technology]
For carrying the pumping equipment that does not allow leaking medium, shield electric machine is used very extensive.At present, be used to carry the shield electric machine formula pump technology of normal temperature and pressure cleaning medium comparatively ripe.And for carrying high temperature, superhigh pressure medium aspect, domesticly still belong to rarely, also do not develop and aly can carry high temperature, the leak free shield electric machine of superhigh pressure medium.
[using novel content]
This practicality is to solve to carry the problem that contains particle, high temperature, superhigh pressure, do not allow leaking medium to carry that a kind of high temperature resistant, superhigh pressure no-leakage pump shield electric machine is provided with novel task.
For achieving the above object, the utility model proposes a kind of high temperature high voltage resistant shield electric machine, comprise stator case, stator, rotor, rolling bearing, the cavity between stator and the rotor is equipped with lubricating oil, it is characterized in that: stator case is provided with cooling chamber, and lubricating oil is housed in the cooling chamber.
Rotor is provided with an accessory impeller, and the cooling chamber employing cooling worm on the stator case is connected with the cavity between stator, the rotor.
Advantage of the present utility model is: by special stator 3 the high compressive load of internal liquid is passed to stator case 1 and bear; Lubricating oil 9 circulates and takes away the stator and rotor heat between epitrochanterian accessory impeller 6 driving stator and rotor; Cooling worm 4 on the stator case realizes that lubricating oil and cooling chamber heat exchange guarantee the stator and rotor temperature in allowed band, guarantee that motor-driven is reliable and stable.Realize motor reliably working under high temperature, high pressure.
[description of drawings]
Fig. 1 is a structure chart of the present utility model.
Referring to Fig. 1,1 is stator case, and 2 is cooling chamber, and 3 is that stator, 4 is cooling worm, and 5 is rotor, and 6 is accessory impeller, and 7 is rolling bearing, and 8 is rolling bearing, and 9 is lubricating oil.
[specific embodiment]
A kind of high temperature high voltage resistant shield electric machine comprises stator case 1, stator 3, rotor 5, rolling bearing 7,8, and the cavity between stator and the rotor is equipped with lubricating oil 9, and stator case is provided with cooling chamber 2, and lubricating oil is housed in the cooling chamber.Rotor is provided with an accessory impeller 6, and the cooling chamber employing cooling worm 4 on the stator case is connected with the cavity between stator, the rotor.
The part that motor and pump are formed is formed closed system, the interior lubricating oil of shield electric machine under high pressure passes to stator case by stator with the high compressive load of internal liquid and bears, accessory impeller drives lubricating oil by bearing rotor gap, flow through the cooling worm circulation and take away rotor and stator heat, lubricating bearings.Guarantee that bearing has good lubricated and good to motor temperature control, realizes motor continous-stable reliably working under high temperature, high pressure.
