Embodiment Construction

[0025] The present invention will be further described below in conjunction with specific examples.

[0026] Such as figure 1 As shown, the outer wall of the novel peristaltic pump is a glass pipe 5, one end of which is sealed with a pump cover 2, and the other end is open. The artificial muscle expansion element 4 is composed of rubber tubes with excellent expansion and sealing properties, and the rubber tubes are connected by flanges 3 . The artificial muscle expansion element 4 is built in the glass tube 5, and there is a gap around it. The side of the pump cover 2 is provided with a water outlet, and the six air pipes 1 pass through the pump cover 2 to lead to the six artificial muscle expansion elements 4 respectively, and the other ends of the air pipes are respectively connected to the air outlets of the six two-position three-way reversing valves , each two-position three-way reversing valve controls a corresponding pneumatic artificial muscle element, so that it can...

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...
