Description
Technical field
The utility model is related to pump technical fields of diving under water, and are specifically related to a kind of immersible pump deep water compensation device.
Background technology
Immersible pump is the important equipment of deep-well water lift.Entire unit pulls the plug work when use, and underground water is extracted
Earth's surface is that domestic water, mine are speedily carried out rescue work, industry cooling, field irrigation, seawater lift, steamer tune carry, it may also be used for fountain scape
It sees.Immersible pump is complete by switch board, submersible cable, lifting pipe, submersible pump and submersible motor composition.Most immersible pumps are entering water
Inside and outside pressure can not be balanced after relatively depth, cause the damage that the pump housing is different degrees of.
Invention content
Problem to be solved in the utility model is to provide a kind of immersible pump deep water compensation device, is pressed when entering the relatively deep outside of water
When power is larger, pump body air pressure can be supplemented, reaches external and internal pressure relative equilibrium, motor is protected not to be destroyed.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of immersible pump deep water ftercompction dress
It sets, the compensation device is mounted on electric motor end cap, and the compensation device includes lifting lug, throttle valve and pressurizer, the ftercompction
Device upper end is equipped with gas outlet, and the lower end of the pressurizer is equipped with water inlet, and the throttle valve passes through escape pipe with the gas outlet
Connection, the water inlet are connected with water inlet pipe, and the escape pipe is connected with the water inlet pipe with the electric motor end cap.
Further, the pressurizer is fixedly connected by a fixing sleeve with the lifting lug.
Further, the compensation device is fixedly connected with the electric motor end cap by the lifting lug.
Further, it is both provided with valve on the gas outlet and the water inlet.
Further, the lifting lug includes the cover of mounting hole and umbrella shape, and the cover bottom end passes through with the electric motor end cap
Bolt is fixed.
Further, the pressurizer is suspended from the electric motor end cap top by the fixing sleeve.
The utility model has the advantages and positive effects of：When enter the deeper external pressure of water it is larger when, the pump housing can be supplemented
Air pressure inside reaches external and internal pressure relative equilibrium, motor is protected not to be destroyed, and ensures that immersible pump has good working performance.

In one embodiment of the utility model, the compensation device is fixed with the electric motor end cap 2 by the lifting lug 3
Connection.The pressurizer 5 is fixedly connected by a fixing sleeve 8 with the lifting lug.On the gas outlet 6 and the water inlet 7
It is provided with valve 11, for controlling switch.The lifting lug 3 includes the cover of mounting hole and umbrella shape, the cover bottom end with it is described
Electric motor end cap 2 is bolted.The pressurizer 5 is suspended from 2 top of the electric motor end cap by the fixing sleeve 8.
The course of work of the utility model is, when diving be pumped into water it is deeper when, hydraulic pressure increases, and water can enter from water inlet 7,
It forces the gas in pressurizer 5 to enter the pump housing by gas outlet 6 and supplements pressure, reach inside and outside pressure balance.
The embodiments of the present invention are described in detail above, but the content is only the preferable of the utility model
Embodiment should not be construed as limiting the practical range of the present invention.It is all according to equivalent change made by the scope of the utility model with
Improve etc., it should all still belong within this patent covering scope.
