Abstract
The utility model relates to a horizontal non -current material quimby pump, including the pump body with install two intermeshing's in the pump body screw rod, bearing, bearing frame and gear box, characterized in that be equipped with at the screw rod drive end: import department's rigid coupling of screw rod has the auger sleeve that is equipped with the feed inlet on it, be equipped with the auger in the auger sleeve, be equipped with auger sleeve end cover admittedly on auger sleeve one side. The advantage is: through the auger with material propelling movement to the import department of screw rod, can effectively compensate the ability of inhaling of pump import like this, the situation of inhaling, the normal transportation process of messenger's screw rod completion is not had in the pump import of having avoided non -current material to lead to. Simultaneously, the coreless auger transport material that can not bond, screw section divide from meshing mutually, make the pump need not to rinse the normal operating that does in a short time.
Description
Technical field
The utility model belongs to displacement type screw pump technology field, particularly relates to a kind of horizontal non-current material two screw pump.
Background technology
Two screw pump is a kind of displacement pump, has been widely used in each industrial circles such as oil, chemical industry and boats and ships at present, has been used for carrying various flow media.When user needs to carry a kind of non-newtonian fluid without flowing power, this material cannot meet pump under normal circumstances and pump that medium is necessary sucts condition, and this kind of material has certain viscosity, structure also needs the Cleaning period extending pump as much as possible.The most heavy body of two screw pump pumped (conveying) medium traditional at present is generally no more than 50PaS, and rotating speed is all less than 500r/min, usually needs to be equipped with retarder and uses.This is because when viscosity is larger, suction resistance is very large, and transmission pump is cavitation very easily; The bubble existed in medium cannot be eliminated.The method that vacuum pump combines with transmission pump that is that some technological process of petrochemical industry uses is come for the higher lubricating grease degassing of viscosity and conveying, production cycle is longer on the one hand, often need repeatedly to circulate and just can produce certified products, so not only affect production efficiency, and use cost is also corresponding higher.
Summary of the invention
The utility model provides a kind of and can carry out effective compensation to the ability that sucts of pump inlet by auger structure for solving in known technology the technical matters that exists, and can improve transport efficiency, reduces the horizontal non-current material two screw pump of use cost.
The technical scheme that the utility model is taked for the technical matters existed in solution known technology is:
Horizontal non-current material two screw pump, comprise the pump housing and be arranged on two intermeshing screw rods in the pump housing, at screw drive end, bearing, bearing seat and gear case are housed, it is characterized in that: the inflow point of described screw rod is connected with the auger sleeve which is provided with inlet point, described auger sleeve, built with auger, auger sleeve side is fixed with auger sleeve end cap.
The utility model can also adopt following technical scheme:
Described auger sleeve end cap is built with the double-row angular contact bal bearing for auger axial location.
Described auger sleeve end cap and screw-conveyer-shaft matching part are provided with packing seal.
Described auger adopts centreless auger structure.
The advantage that the utility model has and good effect are: because the utility model adopts technique scheme, namely the auger of centreless is housed in the inflow point of screw rod, by auger, material is pushed to the inflow point of screw rod, effective compensation can be carried out like this to the ability that sucts of pump inlet, avoiding pump inlet that non-current material causes without sucting situation, making screw rod complete normal course of conveying.Meanwhile, the auger of centreless can not bond convey materials, and screw portion, from being meshed, making pump not clean in a short time and also can normally run.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the birds-eye view of Fig. 1.
In figure: 1, the pump housing; 2, auger sleeve; 3, screw rod; 4, auger; 5, bearing seat; 6, gear case; 7, auger sleeve end cap; 8-1, double-row angular contact bal bearing; 8-2, single row roller bearing; 9, synchronizer gear; 10, packing seal; 11, inlet point.
Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 and Fig. 2, horizontal non-current material two screw pump, the two intermeshing screw rods 3 comprising the pump housing 1 and be arranged in the pump housing, at screw drive end, bearing, bearing seat 5 and gear case 6 are housed, bearing seat is built with the double-row angular contact bal bearing 8-1 for locating and single row roller bearing 8-2, and described gear case is built with synchronizer gear 9.The inflow point of described screw rod 3 is connected with the auger sleeve 2 which is provided with inlet point 11, and described auger sleeve, built with auger 4, auger sleeve side is fixed with auger sleeve end cap 7.
In the present embodiment, described auger sleeve end cap is built with the double-row angular contact bal bearing 8-1 for auger axial location.
In the present embodiment, described auger sleeve end cap and screw-conveyer-shaft matching part are provided with packing seal 10.
In the present embodiment, described auger adopts centreless auger structure.
In the present embodiment, described sealing is preferably the packing seal that installing space is little, cost is low, and cure process is carried out in the corresponding axle journal position of gland sealed, increases the service life of axle.
Principle of work of the present utility model is:
When non-current material two screw pump is started working, first operate auger, turn on pump running when guaranteeing that pump inlet material is sufficient, can formally carry after air emptying in pump, by material being pushed to by auger the inflow point of screw rod, owing to being equipped with centreless auger in the inflow point of screw rod, effective compensation can be carried out to the ability that sucts of pump inlet, and then make two screw pump carry out normal course of conveying.Meanwhile, the auger of centreless can not binding material, and screw portion, from being meshed, making pump not clean in a short time and also can normally run.
The embodiment that the utility model accompanying drawing describes is exemplary, only for explaining the utility model, and can not be interpreted as restriction of the present utility model.
