Abstract

The invention provides a liquid metering and supplying device and supplying method and equipment related to liquid metering and supplying. The liquid metering and supplying device comprises a liquid inlet header pipe, a liquid outlet header pipe and at least two injection pipelines connected between the liquid inlet header pipe and the liquid outlet header pipe in parallel, and further comprises a rack and injection mechanisms arranged on the rack. Specifically, each injection pipeline comprises a liquid inlet branch pipe and a liquid outlet branch pipe which are connected through a three-way valve, the injection mechanisms and the injection pipelines are arranged in a one-to-one correspondence mode, and each injection mechanism comprises an injector with an inlet and an outlet connected with the three-way valve and a driving unit for driving a piston rod of the injector to slide in a reciprocating mode in the axial direction of the piston rod; the driving unit comprises a first rotation driving part arranged on the rack, a lead screw driven by the first rotation driving part and capable of rotating on the rack, and a sliding block in threaded connection with the lead screw and connected with the piston rod. The liquid metering and supplying device is applied to liquid supply, and continuous, stable, constant-flow, metering and constant-quantity precise output of liquid is facilitated.

Description

technical field [0001] The invention relates to the technical field of liquid conveying devices, in particular to a liquid metering and supplying device. At the same time, the present invention also relates to a liquid supply method, and an equipment related to liquid metering supply using the above liquid metering supply device. Background technique [0002] In recent years, with the development of production and the continuous improvement of the quality of life, the application range of metering pumps has been continuously expanded to various industries of national economic production. At the same time, with the development of science and technology and the improvement of production process control requirements, the technical content and technical requirements of metering pumps are becoming more and more stringent, which also forces metering pump manufacturers to continuously accelerate the development speed. [0003] The current metering pumps are mostly reciprocating pu...
