Abstract
The utility model relates to a single-stage single-suction centrifugal pump whose pump body is composed of three components which are a water sucking chamber body, a water pressing chamber body and a supporting body; a bolt passes through screw holes of flanges or through holes of flange bolts arranged on each component to connect the three components into a whole; a sealing gasket is arranged between the water sucking chamber body and the water pressing chamber body. The position varying of a water inlet on the water sucking chamber, a water outlet on the water pressing chamber and the supporting body can be realized by that the mutual corresponding positions of the screw holes of the flanges or the through holes of the flange bolts of each component are adjusted; the same water pump can be installed vertically or horizontally via the mutual replacement of a horizontal supporting body and a vertical supporting body.
Description
The utility model relates to a kind of water pump, particularly relates to the pump housing of a kind of single suction, single stage centrifugal pump.
At present, the water pump of production is made up of the pump housing, pump cover, suspension, rotor part, the suction chamber on its pump housing, pumping chamber, supporting mass three cast solid.The position of the water outlet of the water intake of suction chamber and pumping chamber is fixed like this, and supporting mass also is fixing a kind of mounting type by the vertical or horizontal installation of water pump.In other words, a kind of pump product correspondence a kind of intake-outlet orientation, a kind of mounting type, in order to satisfy user's requirement, producer will produce the multiple water pump of intake-outlet different azimuth and different installation, certainly will cause the raising of cost of production like this, make enterprise on small lot, many kinds, produce, be difficult to form economic scale production that quality of product is difficult to obtain higher assurance.Concerning the user, its alternative, applicability are insular, and the user also can only go to select for satisfying its demand to bigger scope, also brings very big inconvenience to use simultaneously.
The purpose of this utility model is that a kind of mounting type of design possesses vertical, horizontal two kinds of selections, the entery and delivery port orientation of pump can according to user's needs can be a plurality of orientation single-stage, the single-suction centrifugal pump selected.
The utility model is achieved in that the pump housing is made of suction chamber body, pumping chamber body, supporting mass three parts, is connected as a single entity by bolt between flange screw that each parts is provided with or the flange bolt perforation, is provided with sealing gasket between suction chamber body and the pumping chamber body.Flange screw that suction chamber body, pumping chamber body, supporting mass three parts are provided with or bolt penetration hole quantity are 4 multiple, and circumferentially evenly are provided with along flange.
The pumping chamber body is provided with pumping chamber body water port by the impeller outlet position.
The suction chamber body is provided with suction chamber body water port, and suction chamber body and pumping chamber body are established circular groove on the flanged surface that closes, and suction chamber body water port is communicated with circular groove and sliding bearing rear portion, and circular groove is corresponding on the radius orientation with pumping chamber body water port.
Pumping chamber body and pump cover and support connect as one, and the support the other end and motor connect as one.
Supporting mass has vertical supporting mass and horizontal supporting mass by mounting type.
The suction chamber body is when axial water inlet, and supporting mass and suction chamber body are cast as one, thus the time water pump have only horizontal a kind of mounting type.
Because the utility model adopts the pump housing one to be divided into three structure, suction chamber body, pumping chamber body, supporting mass and pump cover are connected as a single entity with bolt by the flange screw or the flange bolt perforation of establishing thereon each other, need only the corresponding position of moving flange screw each other of string or flange bolt perforation like this, just can change the orientation of supporting mass orientation, suction chamber body water intake and pumping chamber body water outlet.The screw of flange or flange bolt perforation number are set at 4 multiple, and along circumferentially evenly setting of flange, purpose is to guarantee that mutual alignment, entery and delivery port orientation can transfer to the integral multiple of 90 ° or 45 °, and the orientation density that screw or bolt penetration hole number are provided with the many more adjustment of quantity is big more.
Because the utility model mounting type adopts vertical or horizontal two kinds of bearing supports, two kinds of bearing supports can exchange, and can select arbitrarily the mounting type of same water pump like this.
As everyone knows, the supporting of the rotary part of traditional typical pump is a cantilever type, and the length that certainly will make pump shaft stretch direction at pump shaft is very long, if vertical layout, height will influence the stability of pump, also is difficult to obtain user's approval in appearance.And another kind of scheme moves to motor internal with supporting, also will cause motor bearings load to strengthen, in addition also within it portion or external means can bear the axial force bearing, in present stage, be subjected to the restriction of the versatility of manufacture cost, auxiliary equipment, this kind structure also is difficult to adopt.What the utility model adopted is to arrange supporting point in the impeller both sides, is a pair of angular contact bearing that can bear thrust load in the distolateral supporting of shaft extension, and opposite side adopts sliding bearing because of structure qualification, possesses the ability of proper functioning in water.For guaranteeing the lubricated and cooling of sliding bearing, must induce one to press the lubricated cooling water of circuit at bearing portion.Thereby pump inside has a water port to communicate with the water absorption bodies water port at the pumping chamber body of nearly impeller outlet end, the pressure water of self can be caused the sliding bearing rear portion, and then to sliding bearing lubricating and cooling.For the path that guarantees lubricated and cooling does not interrupt because of the inlet/outlet bearing change, suction chamber body and pumping chamber body are provided with the end face circular groove on the flanged surface that closes, by its connection effect, it is obstructed to have compensated the water route of causing because of the inlet/outlet bearing change like this.
The utility model satisfies more different needs with fewer basic building block, has improved production economic scale and standardization, generalization degree.The utility model also has vertical, the horizontal two kinds of selections of mounting type, the entery and delivery port orientation of pump can according to user's needs can be a plurality of the advantage selected of orientation, it is suitable for the application of single-stage, single-suction centrifugal pump.
