Abstract
The present invention discloses a two-stage self-sucking pump, which relates to the technical field of the structure of water pumps. A liquid inlet and a liquid outlet are respectively arranged on both sides of a pump body; an electric motor is firmly connected with the upper end of the pump body; the lower end of the output shaft of the electric motor is firmly connected with a vane wheel; an upper horizontal partition plate and a lower horizontal partition plate divide the cavity of the bump body into an upper water-storing cavity, a middle water-storing cavity and a lower water-storing cavity; central holes are respectively arranged at the centers of the upper and the lower partition plates; the vane wheel is arranged in the central hole of the lower horizontal partition plate; a lifting vane wheel, which is arranged in the central hole of the upper partition plate, is firmly connected with the output shaft of the electric motor; the liquid outlet and the liquid inlet are respectively communicated with the upper and the lower water-storing cavities; a check valve is connected with the liquid outlet in series; the electric motor is connected with a support; a sealing vane wheel is arranged between the support of the electric motor and the upper end surface of the upper water-storing cavity. The two-stage self-sucking pump has double dynamic sealing effects and multiple functions such as temperature resistance, pressure resistance, abrasion resistance and 'lifelong self suction after drainage for one time'.
Description
Technical field
The present invention relates to the technical field of structures of water pump.
Background technique
Common water pump adopts packing seal or mechanical seal, because industries such as metallurgy, dressing, digging, environmental protection use on-the-spot water-quality ratio relatively poor, the particle that differs in size is arranged in the water, cause mechanical seal to decrease ring easily, packing seal is used for a long time, and sealing effect is bad, and it is serious to leak.In addition, because inlet ductwork is long, maintenance is relatively more difficult after bottom valve damages.
Summary of the invention
The object of the invention is to design a kind of good sealing effect, the two stage self priming pump of being convenient to safeguard.
The both sides of the pump housing of the present invention are provided with liquid entering hole and liquid outlet respectively, at the fixedly connected motor in pump housing upper end, the fixedly connected impeller in the lower end of the output shaft of described motor; In the pump housing, by upper and lower diaphragm two water storage cavities in upper, middle and lower are set respectively, mesopore is offered at upper and lower diaphragm center respectively, described impeller is arranged in down in the mesopore of diaphragm, arrange to promote impeller on the mesopore of last diaphragm, described lifting impeller is fixedly connected on the output shaft of motor; Liquid outlet and liquid entering hole are communicated with upper and lower two water storage cavities respectively, serial connection one safety check on liquid outlet; Described motor is connected on the support, and the sealing impeller is set between the upper-end surface of electric machine support and last water storage cavity.
The safety check that the present invention is connected in series on liquid outlet can effectively prevent the effect of liquid outlet liquid return, plays the effect of " drainage, lifelong self-priming ".Motor is set directly on the pump housing, has reduced the unnecessary trouble that pipeline length is brought.The setting of lifting impeller particularly of the present invention has the effect that dual dynamic seals.Owing to need not to adopt packing seal, make product have heatproof, withstand voltage, wear-resisting, wait multiple function, can in industries such as metallurgy, chemical fertilizer, papermaking, environmental protection, municipal administration, water purification, weaving, printing and dyeing, digging, dressing, extensively be suitable for.
In addition, in order to prevent when pressure in the pump chamber during greater than rated pressure, water from the gap between electric machine support and the axle to around emerge, install spill pipe relief water additional toward direction outflow, the present invention is also at the upper end of last water storage cavity arranged outside spill pipe.
In order to form siphon in first the use, the present invention connects an air-regulating valve on liquid entering hole.
