Description
Technical Field
The utility model belongs to the technical field of motors, and particularly relates to a pressure balance structure of a submersible motor for a water-filled well.
Background
The submersible motor for water filling well is one kind of slender motor for deep water operation, and the motor casing is made of thin steel plate and is filled with purified water. The motor needs to counteract the high pressure caused by external water pressure and internal heat in deep water through a pressure balance structure.
At present, most of pressure balance structures of the products are single pressure regulating bag structures, the pressure regulating bags are telescopic rubber products, and the internal volume of the motor is changed by arranging the pressure regulating bags with different shapes to balance the internal and external pressure changes. This approach suffers from the following disadvantages: firstly, the pressure regulating bag has a complex structure, most of the pressure regulating bags are in a pagoda shape or a folding shape, the manufacturing process is complex, and meanwhile, the service life of the pressure regulating bag can be shortened due to the complex structure; secondly, the expansion range is limited, once the internal heating is overlarge, the volume expansion is more, the pressure regulating bag can be broken and invalid when the expansion reaches the limit, and even the motor shell can be burst when serious, so that the risk of the frying machine can not be completely eliminated.
Accordingly, the present utility model provides a pressure balancing structure of a submersible motor for a water-filled well, which solves the problems set forth in the background art.
Disclosure of utility model
In order to achieve the above purpose, the present utility model provides the following technical solutions:
The pressure balance structure of the submersible motor for the water-filled well comprises a motor body, wherein a pressure regulating bag and a one-way pressure relief valve are respectively arranged at the bottom and the top of the motor body;
The motor body comprises an upper cover, a shell and a base which are sequentially arranged from top to bottom;
A thrust bearing bracket is arranged in the base, and the opening part of the pressure regulating bag is sleeved on the thrust bearing bracket;
The pressure regulating bag is integrally pressed into the inner cavity of the base, and forms a mutually communicated airtight space with the shell and the upper cover through the opening on the thrust bearing bracket.
The further scheme is as follows: the one-way pressure relief valve is arranged on the upper cover through threads, and the one-way pressure relief valve is sealed with the upper cover through a sealing gasket.
The further scheme is as follows: the water inlet of the one-way pressure relief valve faces the inside of the motor body, and the water outlet of the one-way pressure relief valve is communicated with the outside.
Compared with the prior art, the utility model has the beneficial effects that:
When the motor body submerges in deep water, the external water pressure of the motor body is larger than the internal pressure, the internal components of the motor body and residual air are compressed, at the moment, water outside the motor enters the inner cavity of the base through the opening below the base and compresses the pressure regulating bag to shrink inwards, so that the internal pressure and the external pressure are balanced; when the motor body works underwater, the motor body can generate heat to cause the volume expansion of water and residual air in the motor body, the pressure regulating bag can restore to the original state, and when the expansion further occurs, the one-way pressure relief valve can be opened to discharge the redundant air and water; when the motor stops working, the inside is cooled, the volume is contracted, the external pressure can compress the pressure regulating bag again, and at the moment, the one-way pressure release valve can prevent working medium with impurities from entering the motor body. By the adjusting mode, the internal and external pressure of the motor can be kept in a dynamic balance state all the time, the risk of frying is eliminated, and the motor fault caused by the entry of impurities into the motor is avoided.
