Floating press block device, pump head and peristaltic pump

Abstract

The embodiment of the invention discloses a floating press block device, a pump head and a peristaltic pump. The floating press block device is characterized in that the device is used for the peristaltic pump and comprises a lever shaft (1), a lever shaft support (2), springs (3), a press block (4), adjusting guide sleeves (5), a lever (6), a guide pin (7), a stop collar (8), guide columns (9) and a press block panel (10); the end of a cavity of the press block (4) is provided with at least two springs (3), the guide columns (9) are sleeved with the springs (3), the guide columns (9) are fixed to the lever shaft support (2), and the bottoms of the springs (3) are provided with the adjusting guide sleeves (5). When tube pressing force exceeds pressure provided by the current springs (3), the press block moves upwards, the press block pushes the adjusting guide sleeves (5), and the adjusting guide sleeves (5) are adjusted to compress the springs (3). The compression amount of the springs (3) is adjusted by rotating the adjusting guide sleeves (5). The aim of prolonging the service life of a hose is achieved.

Description

technical field [0001] The invention relates to the technical field of water pump components, in particular to a floating briquetting device, a pump head and a peristaltic pump. Background technique [0002] Peristaltic pump is a new type of industrial pump, which is widely used in pharmaceutical, food, chemical and other industries to transport industrial-specific solution media. [0003] A peristaltic pump consists of a drive, pump head and hose. In the pump head section, fluid is pumped by alternately squeezing and releasing the elastic delivery hose of the pump through a pressure block. Wherein, the hose becomes the largest consumable material of the peristaltic pump due to being repeatedly squeezed by the briquetting block. [0004] There is a non-concentricity error between the working circle of the pressing block and the working circle of the roller in the existing peristaltic pump, so the gap between the pressing block and the hose is not uniform on the working cir...

Problems solved by technology

[0004] There is a non-concentricity error between the working circle of the pressing block and the working circle of the roller in the existing peristaltic pump, so the gap between the pressing block and the hose is not uniform on the working circle, and the pressure of the tube causes the gap between the hose and the pressing block to be too small or too large

Not only reduces the service life of the pump tube, but also affects the uniformity of the pump liquid

At the same time, the extrusion force of the existing briquetting block for the hose is not adjustable, and the long-term extrusion force of the hose shortens the service life of the hose
