Abstract
The utility model discloses a mechanical seal self-priming pump which comprises a motor (1), a pump body (2), an impeller (3), a pump shaft (4), a pump cover (5), a pressure reducing wheel (6) and a mechanical seal device, wherein the pressure reducing wheel (6) is sleeved on the pump shaft (4); the mechanical seal device consists of a bellows (7), a friction pair (8) and a static ring (9); the bellows (7) is fixed on the pump shaft (4); the static ring (9) is fixedly arranged on the pump cover (5); the friction pair (8) is embedded and fixed on the bellows (7); and a seal contact surface is formed between the friction pair (8) and the static ring (9). By adopting the structure, the contact surface between the friction pair and the static ring is compressed through the tension of the bellows, no leakage is ensured at the mechanical seal part, the mechanical seal self-priming pump is more applicable to convey organic solvent and corrosive smoke in the positive pressure working environment, the leakage is effectively prevented, and the environmental pollution is reduced.
Description
Technical field
The utility model relates to a kind of self-priming pump, especially relates to a kind of mechanical seal self-priming pump.
Background technique
In modern industry enterprise produced, self-priming pump was mainly used in factory, chemical industry, irrigation and drainage, mining industry, building industry etc.Especially be fit to pump the sewage and the clean liquid of band particle, suction line need not to fill liquid to the pump housing when need not bottom valve and startup, directly can use, thereby extensively be used.Traditional self-priming pump adopts packing seal mostly, and be aided with the pump of sub-propeller emptying self-priming, but when carrying organic solvent, corrosive fume in the working environments such as (as backward flow types) when this pump is worked in the needs malleation, be easy to generate leakage, so not only can influence the self-priming degree of depth of pump, and can increase the maintenance and the maintenance number of times of pump.
Summary of the invention
The purpose of this utility model provides a kind of compact structure, antileakaging mechanical seal self-priming pump.
The problem of the required solution of the utility model realizes by the following technical solutions: comprise motor, the pump housing, impeller, pump shaft, pump cover, decompression wheel and mechanical seal device, the decompression wheel is sleeved on the pump shaft, mechanical seal device is arranged on the pump cover top and is sleeved on the pump shaft, described mechanical seal device is made up of bellows, friction pair and stationary ring, the high pressure bellows is fixed on the pump shaft, stationary ring is fixedly installed on the pump cover, be embedded on the bellows and be fixed with friction pair, form sealing contact surface between friction pair and the stationary ring.
The said structure that the utility model adopts when fed sheet of a media, by the tension force of high pressure bellows, compresses the face that touches between friction pair and the stationary ring, guarantees that machine sealing position does not have leakage; Be more useful in when carrying organic solvent, corrosive fume in the malleation working environment, more effective preventing leaked, and reduces environmental pollution.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Accompanying drawing is depicted as structural representation of the present utility model
Embodiment
By accompanying drawing as can be known, this mechanical seal self-priming pump, comprise motor 1, the pump housing 2, impeller 3, pump shaft 4, pump cover 5, decompression wheel 6 and mechanical seal device, decompression wheel 6 is sleeved on the pump shaft 4, mechanical seal device is arranged on pump cover 5 tops and is sleeved on the pump shaft 4, described mechanical seal device is made up of bellows 7, friction pair 8 and stationary ring 9, bellows 7 is fixed on the pump shaft 4, stationary ring 9 is fixedly installed on the pump cover 5, be embedded on the bellows 7 and be fixed with friction pair 8, form sealing contact surface between friction pair 8 and the stationary ring 9.The utility model adopts the high pressure bellows mechanical seal, and in the self-priming pump running, medium can seal up at friction pair and stationary ring place, by the tension force of high pressure bellows, makes very tight that the face that touches between friction pair and the stationary ring can press, and guarantees that machine sealing position does not have leakage.When in the malleation working environment, carrying organic solvent, corrosive fume especially, reliable, can effectively prevent to leak, can not produce pollution to external environment condition.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other multi-form variation or changes on the basis of the above description.Here need not also can't give all mode of executions exhaustive, and these belong to conspicuous variation or the change that spirit of the present utility model draws and still are among the protection domain of the present utility model.
