FLANGE MOUNTING STRUCTURE OF A PUMP

摘要

A flange mounting structure of a pump has a pump body, an adapting flange, and a retaining ring. The pump body has an inlet/outlet connection tube with an engaging groove. The adapting flange is mounted around the inlet/outlet connection tube and has an annular recess and an inner shoulder. The retaining ring engages in the engaging groove of the inlet/outlet connection tube, protrudes in the annular recess of the adapting flange, and abuts the inner shoulder of the adapting flange, such that the adapting flange can be held at a specific position on the inlet/outlet connection tube. Accordingly, processes of mounting the adapting flange on the inlet/outlet connection tube and dismounting the adapting flange from the inlet/outlet connection tube can be promptly facilitated.

主权项

1. A flange mounting structure of a pump comprising:
a pump body having an inlet/outlet connection tube, the inlet/outlet connection tube having an engaging groove formed in and around an outer surface of the inlet/outlet connection tube; an adapting flange mounted around the inlet/outlet connection tube and having
a through hole for the inlet/outlet connection tube to protrude through the through hole of the adapting flange;an inner annular sidewall defined around the through hole of the adapting flange;an outer end surface;an annular recess formed in and around the inner annular sidewall of the adapting flange and formed through the outer end surface of the adapting flange; andan inner shoulder formed on the inner annular sidewall and around the through hole of the adapting flange and extending radially; and a retaining ring mounted around the inlet/outlet connection tube, engaging in the engaging groove of the inlet/outlet connection tube, protruding in the annular recess of the adapting flange, and abutting the inner shoulder of the adapting flange.
