It shuts down temporarily it is required that needing to carry out secondary cut to impeller in turn result in pump and is dismounted in working site, repairs.This
When general program need to remove in motor or shaft coupling, the rotor of pump is pulled out from the pump housing then and then is checked, is repaired, more
Change damage or reinstall new part.It at present can not for one people of big specification end suction centrifugal pump when encountering problems
Complete independently operation, it is necessary to the components such as heavy motor, rotor part are hung out using tools such as crane, crowbar, horizon rules,
Then subsequent job, including the installation of very professional water pump rotor, motor installation and concentricity verification are carried out.It is existing in practical operation
, due to narrow space, the uneven congruent factor of tool, dismounting, repair and the installment work of pump are extremely difficult, labor intensity
Height, working efficiency are slow.
For convenience of problem above is solved, need to design a kind of end sucking centrifugal pump sliding door type front end cap assemblies, without tearing open
Unload motor, shaft coupling and rotor part, you can conveniently and efficiently open suction casing and need replacing pump chamber to check, repair or replace
Interior part.It is not necessarily to secondary assembling centrifugal pump, secondary dress motor, shaft coupling after handling exception well and re-starts concentricity school
Test can easily, be quickly installed suction casing, terminate operation.
Invention content：
The task of the present invention is to provide a kind of end sucking centrifugal pump sliding door type front end cap assemblies：
1. it is simple in structure, it is convenient to mount and dismount, keeps pump original structure and size；
2. rapidly radially can disposably position；
3. can quickly being opened by special hinge, closing suction casing to switch pump chamber；
4. the labor intensity of operator can be reduced, a people is independently easily accomplished maintenance, debugging or replaces appointing for parts
Business.
The technical solution adopted by the present invention is：
A kind of end sucking centrifugal pump sliding door type front end cap assemblies, including the pump housing：Pump housing front end is equipped with suction by special hinge
Enter section, special hinge is bolted to suction casing by suction casing, and special hinge is bolted to the pump housing by the pump housing；Suction casing
Front end, which is bolted, is equipped with suction chamber or no suction chamber.
Both sides in special hinge assemble the position of the pump housing and suction casing, separately design circular hole and waist type groove, the hinge of circular hole side
Chain is mounted on bolt on the pump housing, fixed；The hinge of waist type groove side is mounted on suction casing, is locked using bolt,
When needing to open suction casing, first unscrew suction casing connection bolt, suction casing and related accessory are extracted into pump housing assembly seam allowance simultaneously
The waist type groove other side is slid into together with bolt, is rotated integrally by hinge and opens pump suction casing, after fulfiling assignment, then by its entirety
Rotation is assembled to after pump housing cooperation seam allowance and tightens bolt at suction casing it is made to fix to pump housing mating surface.
Suction casing, the pump housing increase the plane being connect with special hinge, increased fitting plane on the basis of traditional design
All it is the monoblock cast together with the pump housing and suction casing.
The vulnerable parts such as impeller are installed, suction casing is mounted on impeller inlet end in the pump housing.
Compared with prior art, the beneficial effects of the present invention are：
End provided by the invention sucking centrifugal pump sliding door type front end cap assemblies are for fast quick-mounting, centrifugal pump and the use designed
Power is small, a kind of simple in structure, design for being easily installed, reduce labor intensity, improving working efficiency.It has the following advantages：
1. this design structure is simple, it is convenient to mount and dismount；
2. rapidly radially can disposably position；
3. can conveniently and efficiently failures such as the impeller of blowdown pump, machine envelope, pump housing；
4. carrying out dismounting and the secondary assembly of motor, shaft coupling and rotor without external force；
5. without verifying concentricity again；
6. the labor intensity of operator can be reduced, improve working efficiency；
7. using heavy, high intensity hinge, weight, reliable in quality can be born.
