The motor shaft of machine and the impeller shaft of the pump housing are respectively independent, and motor shaft is supported by top chock, step, motor shaft and impeller shaft
Connection, impeller shaft passes through pump cover and stretches in pump case to be coupled with impeller, and the first sealing group is equipped between step and motor shaft
Part, the second seal assembly, the first seal assembly are in top, and the second seal assembly at the bottom, fills between pump cover and impeller shaft
There is third seal assembly.
By above scheme as it can be seen that releasing between coupling for motor shaft and impeller between centers, and releasing step and pump cover
Connection, can separate motor with the pump housing, since motor and the pump housing are separable, thus, a motor can be equipped with multiple and different types
Number the pump housing, when only one damage of motor or the pump housing, only need to by the replacement of damage, and then substantially reduce the use of user at
This;In addition, motor and the pump housing are separable, disassembly when sale, transport and maintenance is also helped.
Structure of the invention rationally, reliable performance, it is convenient for disassembly and assembly, be conducive to maintenance and sale, can especially make the use of user
Cost reduces.
