The connection piece (3) penetrates through the through hole (21) to connect with the blind hole (11) in a threaded mode. The wear disc installing structure for the centrifugal pump of the chemical industry has the advantages of being strong in discharge resistance capacity, reliable in seal, convenient to install, reliable in structure, and long in service life.
Description
Technical field
The utility model relates to the chemical centrifugal pump field, is specifically related to a kind of wear disc mounting structure for chemical centrifugal pump.
Background technique
Chemical centrifugal pump is generally for delivery of chemical mediator.When chemical pump carry be the abrasion medium time, the abrasion medium is very obvious for the abrasive action of flow passage components, the high abrasion resisting material finished parts that adopt to improve the life-span of easily damaged parts more at present, but the casting of this class part is relative with processibility just poor, so select half-opened impeller under a lot of occasion.As shown in Figure 1, the wear disc mounting structure of prior art comprises the through hole that the pump housing 1 is provided with, the blind hole that wear disc 2 is provided with and fastening piece 3, the pump housing 1 links to each other by fastening piece 3 with wear disc 2, the through hole that fastening piece 3 passes on the pump housing 1 links to each other with blind hole on the wear disc 2, in case but mounting structure weares and teares, the transmission medium easily through hole from the pump housing 1 releases and causes dielectric leakage, but at some special occasions as carrying inflammable and explosive or during poisonous medium, anti-discharge capacity requirement to pump is higher, therefore causes existing outside mounting technique still can't satisfy the demand of special occasions chemical centrifugal pump.
The model utility content
The technical problems to be solved in the utility model provides that a kind of anti-discharge capacity is strong, sealing is reliable, easy for installation, the wear disc mounting structure that is used for chemical centrifugal pump of reliable in structure, long service life.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of wear disc mounting structure for chemical centrifugal pump comprises blind hole on the pump housing of being located at chemical centrifugal pump, is located at through hole and link on the wear disc, and described link passes through hole and described blind threaded the connection.
As further improvement in the technical proposal:
Described through hole is provided with the taper slotted eye away from an end of blind hole, and an end of described link is provided with the screw section, and the root of described screw section is provided with the taper platform that cooperates with described taper slotted eye.
The other end of described link is provided with fastener head, and described fastener head connects neck by one and links to each other with described taper platform.
Described fastener head is hexagon head.
The utlity model has following advantage:
1, the utility model comprises blind hole on the pump housing of being located at chemical centrifugal pump, is located at through hole and link on the wear disc, link passes through hole and is connected with blind threaded, there is no the hole that is connected with the external world on the pump housing, medium and the extraneous isolation of pump body have effectively been realized, reduced the earial drainage point of pump, had that anti-discharge capacity is strong, sealing is reliable, easy for installation, an advantage of reliable in structure, long service life.
2, the utility model through hole further is provided with the taper slotted eye away from an end of blind hole, one end of link is provided with the screw section, the root of screw section further is provided with the taper platform that cooperates with described taper slotted eye, taper slotted eye and taper platform can effectively transmit pretightening force to neutralization, have that centering is good, reliable in structure, installation be simple and convenient, stressed more balanced, the advantage of long service life.
3, the other end of the utility model link further is provided with fastener head, fastener head connects neck by one and links to each other with the taper platform, knock out during installation that fastener head welds together link and wear disc, polishing flat gets final product again, can further improve the sealing of chemical centrifugal pump.
