Regulating and control method based on novel peristaltic pump

Abstract

The invention relates to a regulating and control method based on a novel peristaltic pump. The peristaltic pump adopts pneumatic artificial muscles as an actuator and comprises a pump cover assembly,artificial muscle expansion components, flanges and air pipelines. A regulated and controlled control system comprises an air compressor, an air storage bottle, a motion control card, a relay module,a proportional pressure-regulating valve, two-position two-way reversing valves and a pressure sensor. Modules of the control system are connected from the air compressor, the air storage bottle, theproportional pressure-regulating valve, the two-position two-way reversing valves and the artificial muscle expansion components to a mechanical mechanism. During regulating and control, the output air pressure of the air compressor, the air pressure of the air storage bottle, the air pressure of a control loop, the working air pressure of the proportional pressure-regulating valve and the working air pressure of the pneumatic artificial muscles are verified sequentially, and the detection results are fed back. The peristaltic pump can transport a fluid medium and is provided with a self-insurance mechanism, and thus a pump body is not damaged during long-time working; the space occupied by the peristaltic pump is saved, and outdoor using is facilitated; the control system is stable and orderly; and the peristaltic pump works with the optimal efficiency, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the fields of transportation using compressed air as a power source, and in particular to a control method based on a novel peristaltic pump. Background technique [0002] Peristaltic pump is a new type of fluid delivery pump after rotor pump, centrifugal pump, diaphragm pump, etc. It is being widely promoted and applied in various industries such as medical treatment, medicine, food, beverage, chemical industry, and smelting. [0003] At present, peristaltic pumps capable of transmitting fluids are required by many industries, such as factory transportation systems, field and emergency situations. Usually these fluids are transported by positive displacement pumps and vane pumps. However, the fluid easily collides with the impeller of the vane pump and damages the pump. In order to adapt to the high pressure of the fluid to be transferred, the positive displacement pump must have a large volume, which makes it inconvenient fo...

AI Technical Summary

Problems solved by technology

However, the fluid is easy to collide with the impeller of the vane pump and damage the pump. In order to adapt to the high pressure of the fluid to be transferred, the positive displacement pump must have a large volume, which makes it inconvenient for outdoor applications and takes up too much space.

[0004] Such a new type of peristaltic pump that is small in size and easy to carry does not have a good control method at present. It only relies on the program in the host computer to control it, so that its work efficiency cannot be improved, or even relatively low.
