Problems solved by technology

[0003] During the pumping process of the peristaltic pump, since the rollers need to be released alternately, the liquid will be sucked back at the moment of release, resulting in a decrease in the output liquid at the outlet end, resulting in fluctuations in the delivery of the peristaltic pump

Abstract

The invention relates to a concave pressing block with slow release areas for a peristaltic pump. The concave pressing block with the slow release areas for the peristaltic pump comprises a pressing block body, one side of the pressing block body is an arc surface, and areas near the apex of at least one end of the arc surface are the slow release areas; and the slow release areas are involute oblique surfaces and / or large angle oblique surfaces and / or involute irregular surfaces. When the slow release areas are arranged at an outlet end, a roller wheel leaves a departure point, the longer slow release areas enable the roller wheel to gradually release the compression on a hose, and the hose gradually returns to an original state; the liquid reflux speed at the outlet end is slower, and the liquid flow rate at the outlet end fluctuates less; when the slow release areas are arranged at an inlet end, the longer slow release areas enable the roller wheel gradually tighten the hose, and the hose narrows slowly; the liquid reflux speed at the inlet end is slower, and the liquid flow rate at the inlet end fluctuates less; and when the slow release areas are arranged at both ends of the arc surface of the concave pressing block, the force of the hose is more balanced, and prolonging the service life of the hose is facilitated.

Description

technical field [0001] The invention relates to the field of peristaltic pumps, in particular to a concave briquetting block with a slow-release area for the peristaltic pump, a peristaltic pump head and a peristaltic pump. Background technique [0002] Peristaltic pump (Peristaltic Pump), also known as hose pump, is a new type of industrial pump, widely used in pharmaceutical, food, chemical and other industries, to transport some sensitive, viscous, strong corrosive, abrasive For grinding, high purity requirements, and media containing certain granular materials. A peristaltic pump is like pinching a fluid-filled hose with your finger, and the fluid in the tube moves forward as the finger slides forward. The peristaltic pump is also based on the same principle except that the fingers are replaced by rollers. Fluid is delivered by alternately squeezing and releasing the pump's elastic delivery hose. Just like pinching the hose with two fingers, with the movement of the f...
