Abstract
The utility model relates to an accessory of a pump, in particular to a middle section wear ring of the pump, and discloses a middle section wear ring of a multi-stage pump. The wear ring is a section of pipe body, a flange is arranged at one end of the pipe body in an integrated mode, and thread grooves evenly distributed are formed in the inner side wall of the pipe body. Due to the fact that the thread grooves are arranged in the inner side wall of the middle section wear ring and can reduce the contact area between the middle section wear ring and an impeller wear ring, the phenomenon of locking of the middle section wear ring and an impeller can be prevented.
Description
Technical field
The utility model relates to a kind of accessory of pump, particularly the stage casing choma of pump.
Background technique
The stainless steel multistage pump mainly is comprised of stator, rotor, bearing, shaft seal, and its stationary part mainly is comprised of suction casing, stage casing, Spit Section, stator etc.; Its rotor portion mainly is comprised of axle, impeller, Balance disc and axle sleeve lamp; Be provided with the stage casing choma between the support body in described impeller and stage casing, the stage casing choma is nested with outside impeller port ring, the stage casing choma is fixed on the support body of stage casing, be provided with the gap between itself and impeller port ring, this gap is very little, pump is prone to locking between stage casing choma and impeller after using a period of time, makes pump normally to use.
Summary of the invention
The utility model provides a kind of stage casing choma of stainless steel multistage pump, and purpose is to solve the problem that is prone to locking between existing stainless steel multistage pump stage casing choma and impeller.
The utility model is one section body, has been wholely set flange at an end of described body, and some uniform thread grooves are set on the madial wall of described body.
When the utility model uses and impeller be used in conjunction with, it is nested with outside impeller port ring, and there is the gap between the two, but the gap is very little, by on the madial wall of stage casing choma, thread groove being set, it can reduce the area of contact with impeller port ring, can prevent from occuring between stage casing choma and impeller the phenomenon of locking.
