Abstract
The utility model discloses a petrol pump for a steamship and a large machine unit. The petrol pump comprises a wire control part, a motor and a pump body part, wherein the pump body part comprises a pump body, an oil inlet, an oil outlet, a pump tire, a shaft and an impeller; the impeller is formed by combining an impeller body connected with the shaft and 5-10 uniformly distributed flexible blades as a whole; the root part of each flexible blade is connected with the impeller body; a spherical end is formed in the top part of each flexible blade; the oil inlet and outlet are formed in the upper part of the pump body; the pump tire is an annular structure and arranged between the oil inlet and outlet; oil holes which are separately communicated with the oil inlet and outlet are formed in the upper part of the pump tire; a thickened circular notch which is used for extruding and deforming the ends of the flexible blades of the impeller to discharge oil is formed in the pump tire. Compared with the prior art, by adopting such structure, the petrol pump for the steamship and the large machine unit disclosed by the utility model has the advantages that the material cost is equivalent, the processing cost, product rejection rate and production cost are reduced, the work efficiency is increased and the maintenance and assembly are convenient.
Description
Technical field
The utility model relates to pump, relates in particular to a kind of steamer and large-scale unit gasoline pump.
Background technique
For adapting to the user demand of different condition, pump of a great variety.Use extensive displacement pump class to have: gear pump, plunger pump, vane pump etc.; Non-displacement pump class has: centrifugal pump, axial-flow pump etc.Gasoline pump comprises the pump housing, pump cover, external gear, internal gear and backbone sealing ring at present, internal gear and external gear engagement, such structure, the required precision of the pump housing, external gear, internal gear is high, side direction, tip circle and external tooth precision are quite high, roughness is little, easily occurs that the pump self-absorption function of assembling after part processing error declines to a great extent even to inhale not oil-feed, can not arrange air and cannot work.Another kind easily occurs that situation is stuck after assembling, and inside and outside gear turns motionless.Product rejection rate is higher, and manufacture cost is higher.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of steamer and large-scale unit gasoline pump, and this kind of steamer and large-scale unit can reduce product rejection rate with gasoline pump, reduces fabricating cost, enhances productivity.
For solving the problems of the technologies described above, the utility model proposes a kind of steamer and large-scale unit gasoline pump, comprise circuit control device, motor and pump housing portion, described pump housing portion comprises pump housing body, filler opening, oil outlet, pump tire, axle and impeller, described impeller forms one by the impeller body being connected with axle and radial 5-10 uniform flexible blade and forms, the root of described each flexible blade is connected with impeller body, the top of each flexible blade has spherical termination, described pump tire is positioned in pump housing body, described impeller is positioned at the cavity of pump tire, described filler opening and oil outlet are positioned at pump housing body top, described pump tire is loop configuration, the top of pump tire has the oilhole communicating with filler opening and oil outlet respectively, the described pump position of foetus has the circle thickening that can make the flexible blade termination extrusion-deformation of impeller be able to oil extraction and lacks between two hydraulic fluid ports.
The both sides of described pump housing body are respectively arranged with protecgulum and middle cover.
Between described protecgulum and pump housing body, be furnished with respectively the wear plate vertical with shaft centre line between middle cover and pump housing body.
The material of described pump tire is stainless steel.
The quantity of the flexible blade of described impeller is six.
A kind of steamer of the utility model and large-scale unit adopt such structure with gasoline pump, and compared with original technology, cost of material is suitable, and processing cost reduces, and reduce product rejection rate, reduce fabricating cost, enhance productivity, and keep in repair easy to assembly.
Brief description of the drawings
