Specific embodiment
The utility model embodiment is described further below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of centrifugal pump, including the pump housing 1, impeller 2, pump shaft 3 and motor 4, the motor 4 is defeated
Outlet is equipped with motor shaft 5, and the impeller 2 is arranged in the pump housing 1 and is connected with one end of pump shaft 3, the pump shaft 3 with leaf
The connected one end of wheel 2 is equipped with mechanical sealing assembly 6, further includes motor housing 7, motor base 8 and coupling shield 9, described
Motor 4 be fixed on motor base 8, on the motor base 8 set adjustable feet 10, described 3 one end of pump shaft leads to
It crosses shaft coupling 11 with motor shaft 5 to be connected, described 9 one end of coupling shield is connected by bolt and the pump housing 1, and the other end passes through company
Acting flange is fixed with motor 4, and in the shaft coupling 11 setting coupling shield 9, coupling shield 9 is used to prevent dust etc. miscellaneous
Matter enters in shaft coupling, improves transmission quality and service life.
Wherein, the adjustable feet 10 is height adjustment bolt；
