Abstract
The utility model provides a self-priming pump, and belongs to the technical field of water pumps. The self-priming pump resolves the problems that an existing self-priming pump is unstable in operation and inconvenient to use. The self-priming pump comprises a pump body, a water tank and a photoelectric pressure switch, wherein the water tank is provided with a water inlet and a water outlet, the photoelectric pressure switch is arranged on the water tank, a gas-water separating partition plate used for dividing the water tank into a left chamber and a right chamber is arranged in the water tank, a gas-water separating baffle is arranged on the upper portion of the left chamber, and an upward inclined gas-water backflow opening is formed between the gas-water separating partition plate and the gas-water separating baffle. The self-priming pump has the advantages of being stable in operation, convenient to use and the like.
Description
Technical field
The utility model belongs to pump technology field, relates to a kind of self-priming pump.
Background technique
Existing full-automatic self-priming pump, is generally comprised of pressurized tank, mechanical pressure switches and the self-priming pump pump housing, and due to pressurized tank being housed, its volume is larger, and mechanical pressure switches regulate inconvenient, move stable not, easily take-off and losing efficacy repeatedly.Moreover, existing wear automatic self-priming pump due to air-water separation dividing plate and runner design unreasonable, air water is can not be fully separated, causes water pump suction lift not high, efficiency is low.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of reasonable in design, self-priming pump stable, easy to use.
The purpose of this utility model can realize by following technical proposal:
This self-priming pump, comprise the pump housing, there is the water tank of water intake and water outlet and be located at the optoelectric pressure switch on water tank, it is characterized in that, in described water tank, be provided with for water tank being divided into the air-water separation dividing plate of left chamber and right chamber, the top of described left chamber is provided with air-water separation baffle plate, forms an air water refluxing opening obliquely between the described gentle water separating baffle of air-water separation dividing plate.
Air-water separation dividing plate is by computational fluid mechanics optimal design, through the formed optimal curve of validation trial.During work, from the mixing wastewater with air liquid of water intake inspiration, be introduced into the right chamber of water tank, then be back to water tank left chamber by air water refluxing opening, during need through half-turn, make to separate in gas from liquid, then through water outlet, discharge.Liquid after separation is got back in runner, again enters water tank and carries out air-water separation, until discharge all gas with water intake after the mixing wastewater with air liquid entering mixes.Optoelectric pressure switch is arranged on water tank, and during work, optoelectric pressure switch can move automatically by preset mode.
This self-priming pump in use, only need just can be realized water pump by control valve and open and close automatically, and has overcome similar water pump operation shakiness in the past, and the defect of take-off, very easy to use repeatedly.
Compared with prior art, this self-priming pump has the following advantages:
By increase the gentle water separating baffle of air-water separation dividing plate in water tank, make the fully separation of mixing wastewater with air liquid, improved pump efficiency; The force value that optoelectric pressure switch can free adjustment starts and stops, can carrying out pressure buffer setting, effectively prevents water pump frequent starting, long service life, good stability.
Accompanying drawing explanation
Fig. 1 is the plan view of a kind of preferred embodiment of providing of the utility model.
Fig. 2 is the side view of a kind of preferred embodiment of providing of the utility model.
In figure, 1, the pump housing; 2, water tank; 21, water intake; 22, water outlet; 3, optoelectric pressure switch; 4, air-water separation dividing plate; 5, air-water separation baffle plate; 6, air water refluxing opening.
Embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
Self-priming pump as shown in Figure 1, comprises the pump housing 1, has the water tank 2 of water intake 21 and water outlet 22 and be located at the optoelectric pressure switch 3 on water tank 2.As shown in Figure 2, be provided with for water tank 2 being divided into the air-water separation dividing plate 4 of left chamber and right chamber in water tank 2, the top of left chamber is provided with air-water separation baffle plate 5, forms an air water refluxing opening 6 obliquely between the gentle water separating baffle 5 of air-water separation dividing plate 4.
Air-water separation dividing plate 4 is by computational fluid mechanics optimal design, through the formed optimal curve of validation trial.During work, from the mixing wastewater with air liquid of water intake 21 inspirations, be introduced into the right chamber of water tank 2, then be back to water tank 2 left chamber by air water refluxing opening 6, during need through half-turn, make to separate in gas from liquid, then through water outlet 22, discharge.Liquid after separation is got back in runner, again enters water tank 2 and carries out air-water separation, until discharge all gas with water intake 21 after the mixing wastewater with air liquid entering mixes.Optoelectric pressure switch 3 is arranged on water tank 2, and during work, optoelectric pressure switch 3 can move automatically by preset mode.
This self-priming pump in use, only need just can be realized water pump by control valve and open and close automatically, and has overcome similar water pump operation shakiness in the past, and the defect of take-off, very easy to use repeatedly.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
