Description
Technical Field
The utility model belongs to the technical field of the well submersible motor, a fill water submersible motor for well that is used for deep well such as field irrigation, domestic water, enterprise's factory and mining industry to carry water relates to, in particular to fill water submersible motor for well submersible motor machine chamber sand control automatic water supply structure.
Background
At present, in the submersible motor for the water-filled well, which is traditionally used in the prior art in China, liquid in a motor cavity can be gradually reduced in the using process. Because of filling the liquid in the submersible motor machine intracavity for the formula well has the effect of cooling down the motor, also have lubricated effect to some parts simultaneously, like graphite bearing. Because the temperature in the motor cavity rises and can not be cooled when the liquid in the motor cavity is reduced, the motor is finally failed, and the service life of the motor is reduced.
Disclosure of Invention
The utility model overcomes the above-mentioned problem that exists, the purpose is for solving fill ability of swimming well submersible motor because of the motor intracavity liquid reduces and lead to the motor high temperature, arouses the problem of motor trouble, through add sand control automatic water supply structure at last leading part, has solved and has filled ability of swimming well submersible motor intracavity liquid to reduce and lead to the motor trouble, reduces the life of motor, provides a fill ability of swimming well submersible motor chamber sand control automatic water supply structure.
The utility model discloses fill that water formula well is with dive motor machine chamber sand control automatic water supply structure content brief:
the utility model discloses fill water formula well and use dive motor machine chamber sand control automatic water supply structure, its characterized in that: the sand control cap is composed of a sand control cap, a PP cotton filter plate, a one-way valve, an upper guide part water supplementing structure mounting hole and reinforcing ribs, wherein the one-way valve is arranged in the upper guide part water supplementing structure mounting hole, the PP cotton filter plate is arranged in the sand control cap, the sand control cap is arranged outside the upper guide part water supplementing structure mounting hole, and the filter plate is arranged between the one-way valve and the sand control cap.
3 reinforcing ribs with included angles of 120 degrees are arranged on the cylindrical surface outside the sand control cap.
The pore size of the PP cotton filter is 1-5 microns, and the pore size of the filter is 5-20 microns.
The utility model discloses fill water formula well and have good sand control and moisturizing function with dive motor machine chamber sand control automatic water supply structure, can utilize the inside and outside pressure differential in motor chamber to motor chamber automatic water supply, the cotton filter plate of PP and the sand soil of filter plate in can filtering the aquatic in the sand control cap prevents that the check valve from being blockked up, and sand control cap and the cotton filter plate of PP inside can be changed. This moisturizing structure can carry out the moisturizing to the motor chamber, solves to fill the interior liquid of water formula well submersible motor machine chamber and reduces, prevents to arouse the overheated trouble of motor because of motor machine chamber lacks water, improves motor life.

Detailed Description
The utility model discloses fill water formula well and use dive motor machine chamber sand control automatic water supply structure is realized like this, combines embodiment and attached drawing now to do specifically explained.
See fig. 1~ 3, water filling formula is submersible motor machine chamber sand control automatic water supply structure for well, by sand control cap 1, the cotton cassette 2 of PP, cassette 3, check valve 4, it constitutes to lead part moisturizing structure mounting hole 5 and strengthening rib 6 on, check valve 4 sets up in leading part moisturizing structure mounting hole 5, be equipped with the cotton cassette 2 of PP in sand control cap 1, sand control cap 1 sets up in the outside of leading part moisturizing structure mounting hole 5, cassette 3 sets up between check valve 4 and sand control cap 1.
Referring to fig. 2 and 3, 3 reinforcing ribs 6 with an included angle of 120 degrees are arranged on the cylindrical surface outside the sand control cap 1.
The pores of the PP cotton filter plate 2 are 1-5 microns, and the pores of the filter plate 3 are 5-20 microns.
Adopt the utility model discloses fill water formula well and sink the motor of motor machine chamber sand control automatic water supply structure and sink back under water, when the liquid in the motor machine intracavity is less, the pressure in the machine intracavity descends, be less than the pressure outside the machine chamber, there is the pressure differential of directional motor machine intracavity portion inside the machine chamber, rivers can flow into sand control cap 1 → PP cotton filter plate 2 → filter plate 3 → check valve 4 under the effect of pressure differential, get into the motor machine intracavity at last, to motor machine chamber automatic water supply, prevent to arouse the overheated trouble of motor because of motor machine chamber lacks water, improve motor life.
The utility model discloses fill water formula well and have good sand control and moisturizing function with dive motor machine chamber sand control automatic water supply structure, can utilize the inside and outside pressure differential in motor chamber to motor chamber automatic water supply, the cotton filter plate of PP and the sand soil of filter plate in can filtering the aquatic in the sand control cap prevents that the check valve from being blockked up, and sand control cap and the cotton filter plate of PP inside can be changed. This moisturizing structure can carry out the moisturizing to the motor chamber, solves to fill the interior liquid of water formula well submersible motor machine chamber and reduces, prevents to arouse the overheated trouble of motor because of motor machine chamber lacks water, improves motor life.
