Abstract

The utility model relates to a relay type negative-pressure submersible pump, which can produce negative pressure through sealing of a submersible pump and a cylinder body. A negative-pressure relay type submersible pump is integrated with a submersible pump through an upper plate and cylinder body connecting screws, a sealing ring and the upper plate and cylinder body connecting screws are then connected with a cylinder body, and the lower part of a pressing return valve at a lower opening of the cylinder body is connected with a lower flange. The utility model realizes relay output of multiple pumps, and since the pumping stroke of each negative-pressure submersible pump is more than 9m, compared with an ordinary submersible pump, the relay type negative-pressure submersible pump can save power by above 15-30 percent due to the output of multiple pumps. The relay type negative-pressure submersible pump has high practicality, is suitable for river reservoirs as well as water wells and mine shafts with various depths, and can realize low energy consumption and large output volume (the more the depth is, the higher the efficiency is).

Description

Relay-type negative pressure submersible pump
Technical field
The utility model relates to a kind of submersible pump with the negative pressure relay-type.
Background technique
Now the submersible pump that uses of China all is to need slip into the submersible pump that just can normally use below the dynamic water level to pump head, no matter and well have in how dark every well and can only use a submersible pump.Along with drawdown causes that diving pumps into well depth and deepens, thereby cause that power of motor strengthens, the starter load strengthens, cable increases, lifting pipe pressure increases, goes into the increasing of well difficulty, line loss increase etc., finally cause pipe pad damage, pipeline breaking, fall pump phenomenon etc.
Summary of the invention
In order to overcome serious problems such as existing motor for submerged pump power, cable, lifting pipe and line loss, the utility model provides a kind of submersible pump with the negative pressure relay-type, this submersible pump can not only reduce power of motor and starter load etc., more can adapt to deep-well with the advantage of many pumps relay and pump up water and realize that power consumption reduces, water-outlet quantity increases.
The technological scheme that its technical problem that solves the utility model adopts is: the present invention utilizes submersible pump and cylindrical shell sealing to produce negative pressure.Negative pressure relay-type submersible pump comprises submersible pump, cylindrical shell, seal ring, automatic control pressure vent, Back Water Valve, goes up lower flange etc.Upper flange plate is connected as a single entity by last dish and cylindrical shell connecting screw and submersible pump, and cylindrical shell top is provided with cable hole, automatic control pressure vent, goes up dish and cylindrical shell connecting screw and cylindrical shell seal ring, and the cylindrical shell bottom is provided with Back Water Valve and lower flange.
The utility model relay-type negative pressure submersible pump is to unite use more than one or one, now unites to use with two relay-type negative pressure submersible pumps to be example.First relay-type negative pressure submersible pump is connected with lifting pipe, and be connected the lower flange continuation down again with second relay-type negative pressure submersible pump to this pumping head depths deeply downward, enters below the water surface up to first relay-type negative pressure submersible pump to get final product.At this moment, water enters between cylindrical shell and the submersible pump from following Back Water Valve, and gas is discharged by automatic control pressure vent in the cylindrical shell, restarts first relay-type negative pressure submersible pump, instantaneous bigcatkin willow is gone into second relay-type negative pressure submersible pump, start second submersible pump water outlet successively and get final product.
The beneficial effects of the utility model are, the utility model is a kind of submersible pump that utilizes the negative pressure relay-type, and it can increase lift, reduce power of motor.The present invention has realized many water pump relay water outlets, inhales journey because of every negative pressure submersible pump all has more than 9 meters, and utilizing and pumping water more is more than the comparable common submersible pump power saving 15%-50%.
