The single stage single suction volute pump of maintenance easy to disassemble.
What the purpose of this utility model was realized in：A kind of single stage single suction volute pump, it includes the pump housing, the described pump housing
Top motor is installed, the both sides of described motor are provided with retainer ring, and the described pump housing is internally provided with retaining ring, institute
The outside for the pump housing stated is provided with the mechanical seal below retaining ring, and the side of described motor is provided with Water pipe bracket,
Outlet pipe is fixed with the outside of described Water pipe bracket, the side of the bottom of the described pump housing is provided with time blowoff valve, described
Main blowoff valve is provided with below secondary blowoff valve.
The described pump housing is mutually fixed with motor by bolt.
The number of described retainer ring is two, is symmetrically distributed in the both sides of motor.
Described secondary blowoff valve is outer-hexagonal bolt arrangement.
Described main blowoff valve is located at the left side of the pump housing, with horizontal plane.
The beneficial effects of the utility model：By the setting of motor both sides retainer ring, it is easy to that motor is fixed, the pump housing
Be internally provided with retaining ring and the mechanical seal of outside improves sealing between the pump housing and motor, in consolidating for Water pipe bracket
It is set under using, the outlet of outlet pipe is flowed out from delivery port upward, beneficial to current；Made by the cooperation of secondary sewage draining exit and main sewage draining exit
With not only the function with blowdown, when needing to overhaul centrifugal pump, opens time blowoff valve and main blowoff valve, Ke Yifang
Being repaired to centrifugal pump just, total the utility model have be connected firmly, good airproof performance, maintenance easy to disassemble the advantages of.
