Abstract
The utility model provides a full automatic pump self-priming device which belongs to the supporting technical field of pumps and is structurally composed of a casing, a water inlet pipe orifice, a float valve, a sealing air inlet pipe orifice, an air suction pipe orifice and a seal decompression component. The water inlet pipe orifice disposed at the bottom of the casing is communicated with an inner chamber of the casing, the float valve is arranged in the casing, the sealing air inlet pipe orifice disposed at the top of the casing is communicated with the inner chamber of the casing, the air suction pipe orifice disposed on one side of the sealing air inlet pipe orifice is communicated with the air inlet pipe orifice, and the seal decompression component is disposed at the upper end portion of the sealing air inlet pipe orifice. Compared with the prior art, the full automatic pump self-priming device of the utility model has the advantages of reasonable design, simple structure, easy processing, convenient use, high automation degree and the like.
Description
1, technical field
The utility model relates to a kind of match equipment of water pump, and the matching used water pump that can make under the effect of internal-combustion engine sucking pipe of specifically a kind of and water pump need not add the full-automatic water pump self-sucking device that diversion gets final product automatic loading water.
2, background technique
Water pump is a kind of pumping water device of guiding to the high position by the water with lower position of driven by motor.At present, the town and country people inject diversion often in advance in water pump with water pump pump water the time, and then starting electrical machinery is extracted into the high position with water, and this is very much inconvenience in actual applications.Though also occurred in recent years being used the water pump self-suction device that water pump is hoisted with air-intake of combustion engine mouth and water pump self-suction device, but need the operator that higher operating experience is arranged in use, be the operating time in a single day to grasp bad, pump water is fall through just, in a word, also there is the improved place of a lot of needs in the water pump self-suction device of prior art.
3, summary of the invention
Technical assignment of the present utility model is at the deficiencies in the prior art, provide a kind of reasonable in design, simple in structure, be easy to process, easy to use, full-automatic water pump self-sucking device that automation length is high.
The technological scheme that its technical problem that solves the utility model adopts is:
Full-automatic water pump self-sucking device, comprise housing, water inlet pipe mouth, float valve, be sealed into gas tube orifice, the air-breathing mouth of pipe and sealing pressure relief assembly, water inlet pipe mouth is arranged on the bottom of housing and communicates with the inner chamber of housing, float valve is arranged among the housing, being sealed into gas tube orifice is arranged on the top of housing and communicates with the inner chamber of housing, the air-breathing mouth of pipe is arranged on the side that is sealed into gas tube orifice and communicates with being sealed into gas tube orifice, and the sealing pressure relief assembly is arranged on the upper end portion that is sealed into gas tube orifice.
Above-mentioned full-automatic water pump self-sucking device, its sealing pressure relief assembly is to be made of support arm, extension spring, extension spring seat, sealing cover and spring reducing valve, sealing cover is arranged on the top that is sealed into gas tube orifice, extension spring is arranged between sealing cover and the support arm by the extension spring seat, and spring reducing valve is arranged on the sealing cover and and is sealed into gas tube orifice and communicates.
Full-automatic its working principle of water pump self-sucking device of the present utility model is as follows:
The suction port of the air-breathing mouth of pipe and internal-combustion engine is joined, the water outlet of water inlet pipe mouth and water pump is joined, starting apparatus combustion engine, and be pressed in the sealing cover that hand will seal pressure relief assembly and be sealed on the gas tube orifice, under the getter action of internal-combustion engine, with self-sucking device, the whole seal space internal air pressure that water pump communicates descends, when air pressure drops to a certain degree, because the existence of inside and outside pressure difference is crushed on sealing cover and is sealed on the gas tube orifice, the water of lower position is drawn in the water pump and among pumping line enters into the housing inner chamber simultaneously, float valve come-up is interrupted the housing inner chamber and is sealed into path between the gas tube orifice under the buoyancy of water effect, the air pressure that is sealed in the gas tube orifice sharply descends, under the atmospheric effect in the external world, spring reducing valve is opened, and inside and outside atmosphere communicates, effect lower sealing cover in extension spring is opened, the work of internal-combustion engine normal suction, water pump is interior owing to also being full of water, so water is continuously exported under the effect of impeller.
Full-automatic water pump self-sucking device of the present utility model compared with prior art, the beneficial effect that is produced is, and is reasonable in design, simple in structure, be easy to processing, easy to use, automation length height.
4, description of drawings
