A Combined High Precision Peristaltic Pump

Abstract

The invention discloses a combined high-precision peristaltic pump, which includes: a lifting drive assembly, a pump body assembly, more than two sets of linear reciprocating motion modules, an anti-backflow device, a pressure tube roller assembly and at least one set of hose assemblies; The lifting drive assembly, anti-backflow device, and hose assembly are all installed on the pump body assembly; more than two sets of linear reciprocating motion modules are installed side by side on the lifting drive assembly, and the linear reciprocating motion module is driven by the lifting drive assembly Perform synchronous lifting movement; each set of linear reciprocating motion modules is equipped with a set of pressure tube roller assemblies; the anti-backflow device is arranged at one end of the linear reciprocating motion module, and the anti-backflow device is used for clamping and loosening hose assembly. The invention has the advantages of simple structure, low cost, saving installation space, reducing energy consumption, and simultaneously meeting the filling precision requirements of different pipelines.

Description

technical field [0001] The invention mainly relates to the technical field of fluid metering, in particular to a combined high-precision peristaltic pump suitable for fluids. Background technique [0002] With the development of technology, many special industries have higher and higher requirements for measurement accuracy and cleanliness, such as biopharmaceutical industry, medical industry, chemical industry, etc. At present, plunger pumps and peristaltic pump technologies are generally used for precise metering of fluids. However, there are still some deficiencies in the existing methods, which greatly affect the accuracy of measurement. [0003] In the existing peristaltic pump technology, it is generally a single-head single-tube peristaltic pump or a single-head multi-tube peristaltic pump. The single-head single-tube peristaltic pump is controlled by a filling power and a filling accuracy, and the precision control is high. However, in existing equipment applicati...

Problems solved by technology

However, in the existing equipment applications, most of the filling equipment is multi-head filling equipment. If a single-head single-tube peristaltic pump is used for filling, it requires a large installation space and very high energy consumption.

The single-head multi-tube peristaltic pump uses one filling power to control the filling of multiple pipelines, which greatly reduces energy consumption and saves installation space, but the filling accuracy of each tube cannot be controlled and adjusted independently, making the filling Poor mounting accuracy
