Abstract
The invention discloses a structure of a horizontal split pump for a dredge pump. The structure comprises an outer pump body, a pump outlet flange (18) of the outer pump body and an inner pump shell (8), wherein the outer pump body is divided into a lower pump body (1) and an upper pump cover (2) by a horizontal splitting surface (17), the whole body of the pump outlet flange (18) is arranged on the pump cover (2), a horizontal splitting surface sealing ring is installed between the pump body (1) and the pump cover (2), the inner pump shell (8) is located on the pump body (1) through a counterbore with two end surfaces extending outwards, the pump cover (2) covers the inner pump shell (8) from the top down, and the pump cover (2) and the pump body (1) are fastened and connected together by a bolt (19). The structure of the horizontal split pump for the dredge pump has the advantages of simple structure, easy process, easy sealing, convenient installation and low cost.
Description
Technical field
The present invention relates to a kind of pump body structure, particularly relate to a kind of dredge pump pump body structure.
Background technique
Big-and-middle-sized bivalve body dredger pump needs between its inner and outer shell to inject and pumps the pressure balance water that fluid pressure equates, the sealing of equilibrirm water all is comparison stubborn problems all the time.Existing big-and-middle-sized bivalve body dredger pump structure is generally opens (see figure 1) from middle vertical diameter to oriented partition with the outer pump housing, and this kind structure is divided into two the pump discharge flange, and this brings difficulty with regard to the sealing of giving this position; Simultaneously this structure in to open the area of face bigger, therefore need the power of sealing just bigger, need to open in the increase pretightening force of face connecting bolt on the one hand, also make the working area increase on the other hand, difficulty of processing increases greatly; From the installing/dismounting aspect, the interior pump case of this structure need use special tool when changing, and operating is not very convenient; From the use aspect, this structure has only foot plate support is arranged on the pump housing, and pump cover is that part of to be unsettled, and this just may bring the hidden danger of vibration to pump.
Summary of the invention
The technical problem of solution required for the present invention provides a kind of processing simple in structure, easy, easy sealing, dredge pump horizontal split pump body structure easy for installation, that cost is low.
In order to solve the problems of the technologies described above, dredge pump provided by the invention horizontal split pump body structure, comprise the outer pump housing and pump discharge flange thereof, interior pump case, the described outer pump housing is divided into the pump housing of bottom and the pump cover on top through opening face in the horizonally split, described pump discharge flange integral body is arranged on the described pump cover, open the face seal circle in being provided with between the described pump housing and the described pump cover, the seam that pump case stretches out by both ends of the surface in described drops on the described pump housing, in described on the pump case, described pump cover connects together by bolton with the described pump housing described pump cover from upper cover.
Adopt the bivalve body dredger pump pump body structure of such scheme, owing to adopted the partition patterns of opening in the level, therefore significantly reduced the area of sealing surface, the sealing ratio of opening face in making is easier to, in the processing of seal groove and sealing plane also than being easier to; Simultaneously, in installation and removal during pump case, first connecting plate is disassembled, more forward and backward cover plate is ejected the pump housing with jackscrew, use crane that pump cover is hung out from top and can see interior pump case, use common lifting tool just interior pump case can be hung out in the pump housing easily; Simultaneously, be to adjust the axial clearance of rotor in connecting plate and back shroud joint by adjusting screw rod, this just is operated under the higher working efficiency impeller of pump easily; It is an integral body that this structure goes out at pump housing outlet(discharge) flange, and becoming with regard to the sealing that makes the outlet port like this is easy to.
In sum, the present invention is a kind of processing simple in structure, easy, easy sealing, dredge pump horizontal split pump body structure easy for installation, that cost is low.
Description of drawings
Fig. 1 is original bivalve body dredger pump structure schematic representation;
Fig. 2 is a structural representation of the present invention;
Fig. 3 is a pump body structure schematic representation of the present invention.
Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments:
Referring to Fig. 2 and Fig. 3, the outer pump housing is divided into the pump housing 1 of bottom and the pump cover 2 on top through opening face 17 in the horizonally split, pump discharge flange 18 integral body are arranged on the pump cover 2, the seam that interior pump case 8 stretches out by both ends of the surface drops on the pump housing 1, pump cover 2 from upper cover on interior pump case 8, the pump cover 2 and the pump housing 1 are fastenedly connected together by bolt 19, in the pump housing 1, open and be processed with O shape ring recess on the face, be used to install O shape circle 12, and at front shroud 3 and the back shroud 4 and the pump housing 1, also be processed with O shape ring recess on pump cover 2 mating faces, be used to install the 2nd O shape circle 11, the bottom surface of the 2nd O shape circle 11 is pressed on the end face of O shape circle 12, plays the effect of the face of opening in the sealing and front and rear cover plate mating face; Connecting plate 13 is connected with bearing spider 14 with back shroud 4 respectively with connecting bolt 16 by adjusting screw rod 15, adjust the axial position that screw rod 15 can be adjusted rotor by regulating, to adjust and connecting plate 13 can be disassembled after screw rod 15 and connecting bolt 16 are dismantled, here the distance of vacating can be removed back shroud 4 from the pump housing, reach the purpose of pump case 8 in can changing.
Referring to Fig. 2 and Fig. 3, adopt the bivalve body dredger pump pump body structure of such scheme,, therefore significantly reduced the area of sealing surface owing to adopted the partition patterns of opening in the level, the sealing ratio of opening face in making is easier to, in the processing of seal groove and sealing plane also than being easier to; Simultaneously, in installation and removal during pump case 8, first connecting plate 13 is disassembled, more forward and backward cover plate is ejected the pump housing 2 with jackscrew, use crane that pump cover 1 is hung out from top and can see interior pump case 8, use common lifting tool just interior pump case 8 can be hung out in the pump housing 2 easily; Simultaneously, be to adjust the axial clearance of rotors in the A place (see figure 3) that connecting plate 13 is connected with back shroud 4 by adjusting screw rod 15, this just is operated under the higher working efficiency impeller of pump easily; This structure is an integral body at pump discharge flange 18, and becoming with regard to the sealing that makes pump discharge flange 18 like this is easy to.
