Abstract
The utility model discloses a novel self-sucking pump made of fluoroplastics alloy, which comprises a pump body, a rear cover of the pump body, an impeller, and a pump shaft driving the impeller to rotate, wherein the pump body comprises a suction chamber, a fluid reservoir and a gas-liquid separation chamber, a front cover is connected at the front end of the pump body, a front cover seal ring is arranged at the connection part of the front cover and the pump body, and the pump body adopts a wholly-formed and integral structure. Because the pump body part adopts the wholly-formed and integral structure, the utility model has less the quantity of parts and better sealing performance, and cannot generate the leakage of toxic and harmful medium.
Description
Technical field:
The utility model relates to a kind of pump, specifically a kind of novel fluoroplastic alloy self-suction pump.
Background technique:
Ordinary Centrifugal Pumps if suck liquid level under impeller, should be poured water during startup in advance, and is very inconvenient, is water in pump, and the suction pipe import need be adorned bottom valve, and during pump work, bottom valve causes very big hydraulic loss.So-called self-priming pump does not need to pour water exactly before startup, through short-time running, by the effect of pump itself, can drink up water, drops into to run well.Fluoroplastic alloy self-suction pump is a kind of gas-liquid mixed centrifugal self-priming pump, at ordinary times at a certain amount of water of pump housing internal memory (medium), behind the pump startup because the turning effort of impeller, the empty G﹠W of suction line mixes fully, and be discharged to gas-liquid separation chamber, in gas-liquid separation chamber, gas is upwards overflowed, water refluxes, return impeller by return port, the residual gas with suction line mixes again, up to the gas in the inlet pipeline is all drained, finish self-priming, and normally draw water.General self-priming pump metal material split-type structural is many, but for carrying some strong acid, during highly basic class medium, metal material is often inapplicable, perhaps narrow application range, these media are now generally adopted plastic material, as: polyethylene, fluoroplastic, Fluoroine-containing plastic alloys etc., plastic material have its Applicable scope widely, but because the moulding narrow limitation of its plastics itself, the pump housing is that composite structure is many, often a pump housing is merotomized, be convenient to like this make, still, comparatively speaking, number of spare parts is many more, and seal point is just many more, and leakage point is also many more like this, for chemical industry, fed sheet of a media all is mordant, in case leak, with regard to the problem that pollutes the environment and cause the personal security aspect.
The model utility content:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of whole moulding, that sealability is good, compact structure and short fluoroplastic alloy self-suction pump of self-priming time made.
The utility model technical solution problem adopts following technological scheme:
Novel fluoroplastic alloy self-suction pump, the pump shaft that comprises the pump housing, pump housing bonnet, impeller and impeller rotation, the pump housing is made of suction chamber, liquid storage room and the three of gas-liquid separation chamber, also be connected with protecgulum at pump housing front end, the joint of the protecgulum and the pump housing is provided with the protecgulum seal ring, and the described pump housing is the integral structure of global formation.
Structural feature of the present utility model also is:
Be installed with a dividing plate in the pump housing, the bottom of described dividing plate and the outer wall of liquid storage room connect firmly, and it is indoor that its top extends to gas-liquid separation.
The water inlet and the preceding cover cavity joint that are positioned at suction chamber on described protecgulum seal ring are provided with safety check.
The overcurrent part of protecgulum, the pump housing, impeller, each parts of pump housing bonnet all is coated with fluoroplastics layer.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the pump housing of the present utility model partly is global formation, integral structure, so amount of parts is few, and the bolt tie point is few in other words, so sealability is better, can not produce the situation that the poisonous and harmful medium is revealed.
2, the utility model is installed with a dividing plate in the pump housing, the bottom of dividing plate and the outer wall of liquid storage room connect firmly, it is indoor that its top extends to gas-liquid separation, fluid partly is divided into two, pump is when starting working, the impeller rotation, gas-liquid mixture is discharged to gas-liquid separation chamber, air-water separation, and gas is overflowed from the pump discharge pipeline, liquid is from the runner backflow liquid storage room in dividing plate left side, arrive impeller outer edge by return port then, carry out air water again and mix, constantly circulation, gas in the suction line is drained, thereby make pump enter normal working quickly.
3, when pump is shut down; pressure medium is directly closed safety check in the pump housing; make in the pump housing that medium can be when not shutting down; the reaction force that medium is huge and cause medium back flow; influence the secondary self-priming of this pump, when pump secondary self-priming, sufficient medium is arranged in the pump housing like this; can moment fluid, energy saving.
4, the flow passage components in the utility model pump housing all are coated with fluoroplastics layer, have increased the corrosion resistance of pump, make its application area wider.
