Motor pump assembly system

This creation is about a pump system, especially a motor pump assembly system.

The traditional pump system is composed of a motor and a pump. The shaft of the motor is connected to the shaft of the pump through a connecting mechanism such as a coupling. The shaft of the pump is connected to the pump rotor, and then driven by the rotation of the motor. The pump rotor is designed to drive the operation of the pump.

However, the conventional pumping system needs to connect individual independent motors and pumps through a connecting mechanism, and the connecting mechanism will easily cause a reduction in the driving performance of the motor driving force, and the connecting mechanism also has wear loss and reduced efficiency.

The elastic member 155 is engaged between the shaft seat 153 and the shaft base 157 to reduce the wear caused by the driving of the shaft base 153 and the shaft base 157, and the elastic member 155 can be directly replaced after long-term use to repair the loss. Coupling 15.

The first side cover 131 of the pump 13 has a first working hole 1311, and the second side cover 135 has a second working hole 1351. When the pump system 10 is actually used, the motor 11 rotates the motor shaft 113 and transmits through the coupling. The connection of 15 drives the rotor 133 of the pump 13, thereby driving the liquid, gas or fluid medium through the first working hole 1311 and the second working hole 1351 of the pump 13 for the purpose of moving the liquid, gas or fluid medium.
