Description

A kind of elastic transmission device of rotor pump

Technical Field

The utility model relates to the technical field of rotor pumps, in particular to an elastic transmission device for a rotor pump.

Background Art

Rotor pumps are also called colloid pumps, cam pumps, three-leaf pumps, universal delivery pumps, etc. Rotor pumps are volumetric pumps. They achieve the purpose of conveying fluids by means of the periodic conversion of multiple fixed volume delivery units in the working chamber. The mechanical energy of the motor is directly converted into the pressure energy of the conveying fluid through the pump. The flow rate of the pump depends only on the change value of the working chamber volume and its change frequency per unit time, and (theoretically) has nothing to do with the discharge pressure; the rotor pump actually uses a pair of synchronously rotating rotors during operation. The rotor is driven by a pair of synchronous gears in the box, and the rotor rotates synchronously in the opposite direction under the drive of the main and secondary shafts. The volume of the pump changes, thereby forming a higher vacuum and discharge pressure. It is particularly suitable for the delivery of sanitary media and corrosive and high-viscosity media.

The Chinese patent application with application number CN201921757936.3 discloses a wear-resistant cam rotor pump, including a motor, a reducer and a pump body, wherein a base is fixedly installed at the bottom of the pump body, and the inner cavity of the pump body is connected to a rotating rotor through a stator rotation, and the rotating rotor includes a telescopic cam and a rotating core. In the utility model, the wear resistance of the inner surface wall of the pump body is ensured by the design of the wear-resistant cushion layer, and the stability of the rotation of the rotating core in cooperation with the telescopic cam is ensured by the design of the sliding ball matching the slide groove. When the device is in normal operation, the spring will support the telescopic cam through the connecting block, ensuring the stability of the rotating rotor. When the material contains a substance with a relatively high hardness, the telescopic cam will compress the spring through the connecting block to shrink the telescopic cam, thereby allowing hard objects to pass normally, thereby avoiding the occurrence of jams and improving the stability of the device.

However, the existing rotor pump still has some defects. When the rotor pump is working, it will produce large vibrations, which will not only produce large noises, but also in serious cases, related parts will be damaged due to collisions caused by the vibrations.
