Embodiment
Referring to Fig. 1 to Fig. 4, the horizontal chemical pump of a kind of modified model of the present utility model is equipped with the pump housing 1, pump cover 2, motor 3, impeller 4, base 5, hitch 6 and pump shaft 7.Hitch 6 is installed between motor 1 and the pump cover 2, and pump shaft 7 is installed in wherein.
One-sided the cutting open of clamping coupling part of pump shaft 7, the profile groove width is 3～5mm, and in general, a little bit smaller axle profile groove width is 3mm, and bigger axle profile groove width is 5mm.In axial direction be processed with two or three pairs of corresponding unthreaded holes 73 and tapped hole 74 in the profile groove side, during assembling, bolt passed from unthreaded hole 73 1 sides be screwed into the tapped hole 74 and fully tighten, make axis hole produce resiliently deformable and and motor shaft combine closely, guarantee that pump shaft 7 firmly is connected with motor shaft, thereby prevent that pump from causing the accident because of factors such as axial force cause pump rotor and motor shaft to break away from when operation.Hole end surface and motor shaft extension end face were fitted and are realized in pump shaft 7 axially locating relied on fully.Tapped hole 74 another one miscellaneous functions are to can be used for mounting and dismounting pump shaft 7.
Pump shaft axially locating direct convenience of the present utility model only need guarantee the applying of an interior hole end surface and motor shaft extension end face, thereby simplify assembly technology during assembling, guaranteed assembly quality.
The left end of pump shaft 7 is installed the rotating ring part of impeller 4 and single mechanical end face seal 9.The adjustment sleeve 10 that can select to exchange mechanical seal expediently is housed on pump shaft 7.By installing additional or removing adjustment sleeve 10, can realize the exchange of two kinds of dissimilar mechanical seals, and other part need not done any change.This is convenient to factory's tissue production on the one hand, has enlarged the application area of pump on the other hand.
O RunddichtringO 11 as static seal is housed between the pump housing 1 and pump cover 2.Mechanical seal 9 as motive sealing is housed between pump cover 2 and pump shaft 7.
This pump adopts the rear opening structure, and the axial left side of the pump housing 1 is provided with medium suction port 13, and the top of the pump housing 1 is provided with exhaust port 14, and the pump housing 1 is by stone bolt 15 horizontal being installed on the base 5.
