Description
Technical field
The invention belongs to water pump technologies, are related to a kind of multistage pump, especially a kind of amphibious multistage pump.
Background technique
Can existing pump be immersed in the water the pipe that can be divided into immersible pump to divide and be typically mounted on liquid level with motor
Road centrifugal pump.Immersible pump is the important equipment of deep-well water lift, and underground water is extracted earth's surface, be domestic water, mine speedily carry out rescue work, work
The essential pumping equipments such as industry cooling, field irrigation, seawater lift, steamer tune load, in addition can also be used in fountain landscape,
Entire unit needs the work that pulls the plug when use, and submersible pump is because motor is by the type of cooling and intake-outlet dived under water
Structure type can not be used in land.And the cooling of known pipeline pump is that fan blade cooling is driven by shaft, degree of protection
Low, cannot dive under water use.
Summary of the invention
The purpose of the present invention is there is the above problem in view of the prior art, proposes a kind of good cooling results while having
There is pipe to be pressurized and dive under water and pumps the amphibious multistage pump of function.
Object of the invention can be realized by the following technical scheme:
This amphibious multistage pump is successively arranged top in the pump housing including the tubular pump housing with inlet and outlet
Lid, upper ball cover and lower ball cover are equipped with pump motor, the lower ball cover between the upper ball cover and lower ball cover
The water sucting cavity being connected to water inlet is formed between water inlet, the shaft of the pump motor stretches in the water sucting cavity, institute
The multi-stage impeller being sheathed in shaft is equipped in the water sucting cavity stated, which is characterized in that set between the top cover and lower ball cover
There is the tubular shell for closing pump motor, there is water passage between the shell and ontology, the water passage
Lower end is connected to water sucting cavity, and the upper end of the water passage is connected to water outlet.
In above-mentioned amphibious multistage pump, the water outlet is located at the top of the pump housing, and the water inlet is located at
On the side wall of pump housing bottom, the water inlet is equipped with standard pipe thread.
When work, pump motor operation drives multi-stage impeller rotation, water is drawn into water sucting cavity from water inlet, by
It is gradually increased in the pressure in water sucting cavity, water can flow to water outlet along water passage, be finally discharged by water outlet, realization is drawn water
Movement.
When being used as immersible pump, water inlet is located on the side wall of pump housing bottom, the standard pipe thread being arranged on water inlet
The sundries that can be effectively prevent in its extract water effectively extends the service life of this amphibious multistage pump.When used pipe pressurizing
When pump, it is connect by taking over the standard pipe thread of water inlet, water cools down pump motor through water passage, prevents water
Pump motor is burnt, and effectively extends the service life of the amphibious multistage pump.
Compared with prior art, this amphibious multistage pump has the advantage that
It can be used as immersible pump and blower pump for pipeline, do not draw impurities in water when as immersible pump, when being used for blower pump for pipeline, flow through
The water of water passage effectively cools down pump motor, and good cooling results, shelf life is long, and applied widely, operation
When noise it is low, the degree of protection of pump motor is high, has conveniently realized 1 pump while having met the pumping in two places in land and water
Water is used.

Specific embodiment
Following is a specific embodiment of the present invention in conjunction with the accompanying drawings, technical scheme of the present invention will be further described,
However, the present invention is not limited to these examples.
Amphibious multistage pump as shown in Figure 1, including the tubular pump housing 1 with water inlet 11 and water outlet 12, the pump housing 1
It is inside successively arranged top cover 2, upper ball cover 3 and lower ball cover 4, pump motor 5 is equipped between upper ball cover 3 and lower ball cover 4, under
The water sucting cavity 13 being connected to water inlet 11 is formed between bearing cap 4 and water inlet 11, the shaft of pump motor 5 stretches to the suction
In water cavity 13, the multi-stage impeller 6 being sheathed in shaft is equipped in water sucting cavity 13.
As shown in Figure 1, being equipped with the tubular shell 7 for closing pump motor 5, top cover 2 between top cover 2 and lower ball cover 4
It is tightly connected with the shell 7, lower ball cover 4 and the shell 7 are tightly connected, will be between the shaft of pump motor 5 and lower ball cover 4
It is sealed.As shown in Figure 1, having water passage 14 between shell 7 and ontology, the lower end of aquaporin is connected to water sucting cavity 13, mistake
