The peristaltic pump is stable in flow, low in cost and low in noise, the operation flow of a pump pipe is effectively stabilized, the operation cost is low, the operation noise is greatly reduced, a power output shaft of a motor extends into the pump body from one side of the pump body, a motor body of the motor is fixedly arranged in the pump body, and a pump cover covers and is clamped to the other side of the pump body in a matched mode. The pump body and the pump cover are matched to form a pump chamber, the support is arranged on the inner side of the pump cover through a bearing, the three transverse supporting rods are all movably sleeved with sleeves, the pump pipe is sleeved with gaps between the sleeves and the pump cover, the sleeves extrude the pump pipe by rotating the support, and the cover piece is arranged on the end side of the pump cover to limit the sleeves on the supporting rods. A power output shaft of the motor, the support and the center axis of a bearing of the support are located on the same straight line, the ends of three transverse supporting rods of the support are correspondingly inserted into center holes of the three planetary gears, and the support is driven to rotate through revolution of the three planetary gears.
Description
technical field [0001] The invention relates to a peristaltic pump with stable flow rate, low cost and low noise, which belongs to the technical field of peristaltic pumps. Background technique [0002] In the existing peristaltic pump, due to the shaking of the pump tube, the stable transmission of the pump tube flow is affected, and there is eccentricity in the power transmission process, resulting in large power loss and increased operating costs. In addition, there is dry friction between the bracket and the pump cover, and the noise is relatively high. Big. Contents of the invention [0003] The invention overcomes the shortcomings of the prior art, provides a peristaltic pump with stable flow, low cost and low noise, which effectively stabilizes the running flow of the pump tube, has low running cost, and greatly reduces running noise. [0004] In order to solve the above technical problems, the technical solution adopted in the present invention is: a peristaltic p...
