Abstract
The invention discloses a dirt removing device of a self-priming type sewage centrifugal pump. The dirt removing device comprises a motor, a middle support and a pump cover, wherein the middle support is mounted at the outer side of the motor; the pump cover is fixed with the middle support; an impeller chamber is formed between the pump cover and the middle support; the output end of an output shaft of the motor is positioned in the impeller chamber, and is provided with an impeller; a gas-liquid separation chamber is arranged at the middle part of the pump cover; a liquid storage chamber is formed in the bottom of the pump cover; the gas-liquid separation chamber is communicated with the liquid storage chamber; the liquid storage chamber is communicated with the impeller chamber; the impeller chamber is communicated with a suction pipe; the top of the gas-liquid separation chamber is communicated with an outlet; a dirt removing port is formed in the pump cover, and is communicated with the suction pipe and the liquid storage chamber; and a dirt removing cover is arranged on the dirt removing port. The dirt removing device brings more convenience for removing dirt in a self-priming pump.
Description
Technical field
The present invention relates to self-priming pump.
Background technique
Liquid storage room and the impeller inlet place of self-priming pump easily accumulate dirt; during in particular for drawing the sewage containing a large amount of mud; therefore needing frequent cleaning, when shutting down dirt in cleaning pump, usually the pump housing will be disassembled to ensure that the dirt of pump body is all eliminated.
On the one hand when clearing up the dirt in self-priming pump, some positions of pump body cannot be swept and put in place, just can clear up dirt after must dismantling water pump, and it is cumbersome sometimes to dismantle the pump housing, bring great inconvenience therefore to dirt in cleaning pump.
Summary of the invention
Technical problem to be solved by this invention is just to provide a kind of decontamination apparatus of self-priming sewage centrifugal pump, dirt in easy cleaning pump.
For solving the problems of the technologies described above, the present invention adopts following technological scheme: a kind of decontamination apparatus of self-priming sewage centrifugal pump, comprise motor, in hold and pump cover, hold in described and be arranged on motor outlet side, described pump cover with in hold fixing, described pump cover and in hold between be provided with blade wheel chamber, the output terminal of described motor output shaft is positioned at blade wheel chamber, the output terminal of described motor output shaft is provided with impeller, gas-liquid separation chamber is provided with in the middle part of described pump cover, bottom is provided with liquid storage room, described gas-liquid separation chamber and liquid storage room, described liquid storage room is communicated with blade wheel chamber, described blade wheel chamber is communicated with suction pipe, described gas-liquid separation chamber top and outlet, described pump cover is provided with scrubbing mouth, described scrubbing mouth is communicated with suction pipe and liquid storage room, described scrubbing mouth is provided with scrubbing lid.
Preferably, described scrubbing lid is fixed by bolt and pump cover, is provided with seal ring between described scrubbing lid and pump cover.
Preferably, described inlet axis is vertical with outlet axes.
Preferably, the jointing of described import and gas-liquid separation chamber is provided with one-way valve.
Preferably, described one-way valve is rubber ring structure.
In self-priming pump pump housing bottom, corresponding liquid storage room and blade wheel chamber's suction port are provided with scrubbing mouth in the present invention, and design scrubbing lid, in needs cleaning self-priming pump during dirt, open the scrubbing lid of self-priming pump, can take out stains, therefore greatly facilitate the dirt of cleaning self-priming pump inside.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
Fig. 1 is overall construction drawing of the present invention;
Fig. 2 is pump body structure figure.
Embodiment
As depicted in figs. 1 and 2, the present invention is a kind of decontamination apparatus of self-priming pump, comprise motor 3, in hold 2 and the pump housing 1, hold 2 in described and be arranged on motor outlet side, the described pump housing 1 with in hold 2 and fix, the described pump housing 1 and in hold 2 between be provided with blade wheel chamber 16, the output terminal of described motor output shaft 31 is positioned at blade wheel chamber, the output terminal of described motor output shaft is provided with impeller 21, described pump housing top is provided with gas-liquid separation chamber 17, bottom is provided with liquid storage room 14, return port is had to be communicated with blade wheel chamber in the middle part of described liquid storage room, described gas-liquid separation chamber top is communicated with outlet 12, the described pump housing is provided with scrubbing mouth, described scrubbing mouth is communicated with blade wheel chamber suction port 13 and liquid storage room, described scrubbing mouth is provided with scrubbing lid 15.Described scrubbing lid 15 is fixed by bolt and the pump housing 1, is provided with seal ring 151 between described scrubbing lid and the pump housing, and sealing when seal ring guarantee scrubbing lid is airtight, bolt arrangement can realize quick-detachment and the installation of scrubbing lid.
Impeller to be changed the line of production raw negative pressure in blade wheel chamber's inward turning, initial gas enters blade wheel chamber and produces gas-liquid mixture with the liquid stored in advance, gas-liquid mixture is separated in gas-liquid separation separated type, liquid enters liquid storage room, flow back to blade wheel chamber by return port, gas is discharged from outlet, circulates and so forth, until the air emptying of inlet ductwork, reach self-absorption function.Then sewage is sucked by import, by outlet effluent.Described inlet axis is vertical with outlet axes, and inlet is provided with one-way valve 111, and described one-way valve is rubber ring structure, one-way valve opens during start, and during shutdown, one-way valve is closed downwards due to gravity.Described outlet and gas-liquid separation chamber are directly through, and sewage flows through blade wheel chamber after being sucked by import, finally discharge from outlet.
After Long-Time Service; easily dirt is accumulated in liquid storage room and suction eye; when shutting down dirt in cleaning self-priming pump; only need the scrubbing lid opening self-priming pump, the dirt in each corner in the pump housing can be removed, and do not need the pump housing to disassemble; therefore dirt in pump is conveniently known; improve scrubbing efficiency, saved manpower, and the normal working performance of self-priming pump can be recovered rapidly.
