TECHNICAL FIELD

[0002] The soft tube pump belongs to the category of peristaltic pumps. The peristaltic pump is a rotor type volumetric pump, and is named after its working principle similar to the digestive tract to transport gas, solid and liquid three-phase medium in a peristaltic manner. The soft tube pump has no valve and no seal, and the only part in contact with the medium is the inner cavity of the rubber soft tube. The rotor for compressing the soft tube is completely independent of the medium. The soft tube pump has better self-suction capacity than other pumps, and can almost produce perfect vacuum to suck liquid. The soft tube pump can transport gas-containing liquid and foam liquid without air resistance. The soft tube pump is also strong in transporting high-viscosity and shear-sensitive medium. The fixed displacement per rotation is independent of the outlet pressure, and the soft tube pump is a natural metering pump.

The soft tube pump transports substances by means of the rolling wheel extruding the soft tube to alternately stretch and contract. Due to the rapid rotation of the motor, the soft tube cannot quickly recover to the maximum extent of the original shape and starts to be compressed again, so that the elastic tension of the soft tube is easily reduced, thereby affecting the speed of transporting substances.
