Description

Technical Field

[0001] The utility model belongs to the technical field of peristaltic pumps, and in particular relates to a peristaltic pump dosage calibration device. Background Art

[0002] Peristaltic pumps are composed of three parts: driver, pump head and hose. The main competitive advantages of peristaltic pumps are that the fluid is isolated in the pump tube, the pump tube can be quickly replaced, the fluid is reversible, it can run dry, and the maintenance cost is low. The peristaltic pump system is composed of three parts: peristaltic pump driver, peristaltic pump head, and peristaltic pump tube. Peristaltic pumps are a new type of fluid delivery pump after rotor pumps, centrifugal pumps, diaphragm pumps, etc. It is being widely promoted and applied in various industries such as medical treatment, medicine, food, beverages, chemicals, and smelting. When the peristaltic pump is working, it relies on the roller assembly to rotate in an arc to extrude or the pressure block assembly to extrude the elastic hose in a serpentine straight line. The roller assembly or the pressure block assembly requires more than two rollers or pressure blocks to extrude the elastic hose to transport the fluid.

[0003] At present, when an existing peristaltic pump performs dosage calibration on the delivered liquid through a dosage calibration device, it is usually necessary to insert the hose at the output end into the container of the dosage calibration device, and then deliver the liquid into the container for dosage calibration. However, as the water level in the container rises, the water flowing out of the infusion tube inserted deep into the dosage calibration device will become smaller and smaller as the water pressure increases, thereby reducing the water delivery efficiency of the peristaltic pump.
