Abstract
The utility model provides an efficient energy-saving self-priming pump, namely a centrifugal pump capable of automatically pumping water without filling water in a suction pipe. The self-priming pump consists of a pump body, a pump cover and an impeller. A water inlet and a water tank are arranged on the pump body, and the water tank is communicated with the pump body. The utility model is characterized in that a rotating shaft is arranged in the pump body by a bearing, one end of the rotating shaft extends out of the pump body, and the impeller is arranged at the other end of the rotating shaft; a gas and water separating partition plate is arranged at the communication part of the water tank and the pump body, the water tank is divided by the gas and water separating partition plate into a left part and a right part, a gas and water separating baffle is arranged above the left part of the water tank, and a gas and water backflow opening which is slant upward is arranged between the gas and water separating partition plate and the gas and water separating baffle; the pump cover is connected to the front end of the pump body by a nut. Gas and water mixed liquid can be fully separated, and the pump efficiency is improved. As the pump cover is connected to the front end of the pump body, the impeller and other easily damaged components can be exchanged without disassembling the pump body during repair. The structure is simple, and the disassembly is convenient.
Description
Technical field
Self-priming pump is a kind of centrifugal pump that water just can automatically draw up water that do not need to be full of in suction line.The utility model is a kind of energy-efficient self-priming pump.
Background technique
Existing self-priming pump, because air-water separation dividing plate and runner design are unreasonable, air water can not fully separate, and causes water pump to inhale Cheng Bugao, generally inhale journey and be no more than 8 meters, and low from efficient, maintenance dismounting inconvenience.
Summary of the invention
The purpose of this utility model is to inhale the not low defective of high efficiency of journey in order to overcome existing self-priming pump, invents a kind of energy-efficient self-priming pump.
The purpose of this utility model realizes as follows: described energy-efficient self-priming pump, by the pump housing, pump cover, impeller is formed, the pump housing is provided with water intake and water tank, water tank is communicated with the pump housing, it is characterized in that: be provided with rotating shaft by bearing in the pump housing, one end of rotating shaft stretches out in pump housing outside, the other end of rotating shaft is provided with impeller, water tank is provided with the air-water separation dividing plate with the place of connection of the pump housing, the air-water separation dividing plate is divided into a left side to water tank, right two-part, the top of water tank left-hand component is provided with the air-water separation baffle plate, forms an oblique air water refluxing opening that makes progress between the gentle water separating baffle of air-water separation dividing plate.
Described pump cover is connected the front end of the pump housing by nut.
Good effect of the present utility model is as follows: the utility model designs the gentle water separating baffle of rational air-water separation dividing plate in the pump housing, and air water mixed solution physical efficiency is fully separated, and has improved pump efficiency, and the self-priming height has been saved the energy near 10 meters; Because pump cover is the front end that is connected the pump housing, get final product so only tear pump cover open during maintenance, not needing the whole pump housing dismantled is easily damaged partss such as replaceable impeller, mechanical seal, simple in structure, easy accessibility.

Embodiment
Shown in Figure 2 as Fig. 1, described energy-efficient self-priming pump, by the pump housing 1, pump cover 2, impeller 3 is formed, the pump housing 1 is provided with water intake 4 and water tank 5, water tank 5 is communicated with the pump housing 1, it is characterized in that: be provided with rotating shaft 7 by bearing 6 in the pump housing 1, one end of rotating shaft 7 stretches out in the pump housing 1 outside, the other end of rotating shaft 7 is provided with impeller 3, water tank 5 is provided with air-water separation dividing plate 9 with the place of connection of the pump housing 1, air-water separation dividing plate 9 is divided into a left side to water tank 5, right two-part, the top of water tank left-hand component is provided with air-water separation baffle plate 10, forms an oblique air water refluxing opening 11 that makes progress between the air-water separation dividing plate 9 gentle water separating baffle 10.
Described pump cover 2 is connected the front end of the pump housing 1 by nut 8.
During work, air water mixing material from the water intake inspiration, advanced in the water tank right-hand component, be back to water tank left-hand component by the air water refluxing opening again, need therebetween to make in the gas from liquid and separate through half-turn, discharge through water outlet then, liquid after the separation is then got back in the runner, mixes with intake pipe air water mixing material laggardly to go into water tank and carry out air-water separation, until discharging all gas.
Claims (2)
