Abstract

The invention relates to an accurate quantitative control system and control method for a peristaltic pump. The system comprises a driver, a pump head, a pipeline switching device, a metering pipelineand a discharging pipeline, wherein an elastic hose is arranged in the pump head, and the outlet end of the elastic hose is connected with the pipeline switching device; the driver drives the pump head to operate to pump liquid in the pipeline to the outlet end of the elastic hose; the driver is electrically connected with the pipeline switching device, and capable of controlling the pipeline switching device to switch the outlet end of the elastic hose to communicate with the metering pipeline or the discharging pipeline; and in response to the fact that the driver drives the pump head to operate to a preset starting position, the pipeline switching device is driven to switch the outlet end of the elastic hose from the state of communicating with the discharging pipeline to the state ofcommunicating with the metering pipeline. The accurate quantitative control system for the peristaltic pump realizes precise quantitative conveying of the peristaltic pump, and has the advantages of being simple in structure, high in quantitative accuracy, capable of realizing continuous operation, high in conveying efficiency, low in cost and wide in adaptability.

Description

technical field [0001] The invention belongs to the technical field of peristaltic pumps, and in particular relates to a peristaltic pump precise quantitative control system and a control method thereof. Background technique [0002] A peristaltic pump generally includes a driver (not shown), a pump head 101 and an elastic hose 102, such as figure 1 shown. When the peristaltic pump is working, the elastic hose 102 is filled with liquid 103, and the driver drives the roller 104 in the pump head 101 to rotate through the shaft 108, and a plurality of rollers 105 on the periphery of the roller 104 face the hose briquetting block during the rotation of the roller. 106 alternately squeezes and releases the elastic hose 102 sequentially, thereby forming a negative pressure in the elastic hose 102 and pumping the liquid 103 . Compared with other pumps, peristaltic pumps have the characteristics of good controllability, no pollution, cleanliness, and certain transmission accuracy....
