Description
Technical field
The utility model relates to a kind of pump housing more particularly to a kind of twin pipe circle pumps.
Background technique
The mechanical rotary seal of centrifugal pump generally comprises rotating ring, stationary ring in currently available technology, wherein stationary ring and machine
It is fastened and connected between shell by sealing ring, rotating ring is socketed in shaft and rotates with shaft, has phase between dynamic and static ring
Have to the abutting end face of pivoting friction, between end face and rotate closed surface accuracy, rotating ring pushes spring by the other end
Effect abuts dynamic and static ring between end face and keeps abutting pressure appropriate, it is ensured that the sealing effect between dynamic and static ring；This knot
The shortcomings that structure is, pushes spring and is socketed on shaft and with pivot, goes out when shaft installation accuracy is insufficient or service wear
Now work middle axial motion the case where when, compensation can not be provided moment to keep abutting end face between dynamic and static ring by pushing spring
Fitting, causes to leak.
Utility model content
The utility model provide in order to solve problem above a kind of structure is simple, production cost is low, it is easy for installation, sealing
Property it is good, stable, extend motor service life, antidetonation heat dissipation twin pipe circle pump.
The technical solution of the utility model is: the circulating pump includes a pair of of pump housing of bilateral symmetry connection, described
A pair of of pump body connection, a pair of of pump housing are separately positioned on pedestal, and the pump housing includes motor, shield, gear
The top of the pump housing, the electricity is arranged in hydrosphere, sealing shroud, electric machine support, impeller, impeller nut, pump main body, the motor
Output shaft is arranged in machine lower part, anti-seismic protecting cover is arranged outside the output shaft, the retaining ring is fixed at output shaft
Middle part, the output shaft are connected with impeller, and the sealing shroud is fixed at the engaging portion of impeller and output shaft, described
Electric machine support be arranged and in motor lower portion and be connected on pedestal, the impeller setting is in pump main body, the impeller spiral shell
Impeller is connected with exporting axis integral, described shield equipped with several cooling fins by mother.
The utility model structure is simple, production cost is low, easy for installation, good airproof performance, stable, extension motor use
Service life, antidetonation heat dissipation.
Detailed description of the invention
