Description
Technical field
The utility model relates to a kind of sewage pump, particularly a kind of direct-connection type vertical sewage pump.
Background technique
The motor of existing vertical sewage pump is the standard axle motor at present, connect for coupling between pump and the motor, design has assemblies such as electric machine support, axle, upper and lower bearing, upper and lower bearing gland between pump and motor, assembly is more, concentricity requirement is difficult to guarantee, the whole height of pump is higher, and center of gravity is also higher, has influenced the operation stability and the working life of pump.
Summary of the invention
The purpose of this utility model is that the motor that solves vertical sewage pump in the prior art adopts the existing the problems referred to above of standard axle motor, and a kind of direct-connection type vertical sewage pump is provided.The utility model designs a kind of direct-connection type vertical sewage pump, comprise water retaining ring, screw, mechanical seal, pump cover, impeller, seal ring, the pump housing, screw, the impeller pressing plate, screw, it is characterized in that: be an extension shaft motor on the pump housing, water retaining ring is enclosed within on the axle of extension shaft motor, between the pump housing and the extension shaft motor pump cover is arranged, use screw attachment between extension shaft motor and the pump cover 5, the cylindrical of mechanical seal is enclosed within the endoporus of pump cover, mechanical seal is enclosed within on the axle of extension shaft motor, impeller set is on the axle head of extension shaft motor, the wheel hub end face of impeller withstands mechanical seal end surface, impeller is connected with the extension shaft motor by impeller pressing plate and screw, pump cover is enclosed within on the endoporus of the pump housing, by screw attachment.The utility model has the advantages that compact structure, volume is little, and beautiful shape operates steadily, and assembly concentricity height is easy for installation.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing is a structural representation of the present utility model,
Embodiment
Comprise water retaining ring 1 among the figure, screw 2, mechanical seal 3, pump cover 4, impeller 5, seal ring 6, the pump housing 7, screw 8, impeller pressing plate 9, screw 10, it is characterized in that: be an extension shaft motor 11 on the pump housing 7, water retaining ring 1 is enclosed within on the axle 12 of extension shaft motor 11, between the pump housing 7 and the extension shaft motor 11 pump cover 4 is arranged, connect with screw 2 between extension shaft motor and the pump cover 4, the cylindrical of mechanical seal 3 is enclosed within the endoporus of pump cover 4, mechanical seal 3 is enclosed within on the axle 12 of extension shaft motor 11, impeller 5 is enclosed within on axle 12 ends of extension shaft motor 11, the wheel hub end face of impeller 5 withstands mechanical seal 3 end faces, impeller 5 is connected with extension shaft motor 11 by impeller pressing plate 9 and screw 8, pump cover 4 is enclosed within on the endoporus of the pump housing 7, is connected by screw 10.Owing to removed assemblies such as coupling between pump and the motor and the electric machine support between pump and the motor, axle, upper and lower bearing, upper and lower bearing gland, guaranteed the shaft concentricity of pump, motor, reduced the height of pump, simultaneously also reduce center of gravity, improved the operation stability and the working life of pump.
