Proportion-adjustable automobile fluid matching control system and control method thereof

Abstract

The invention relates to a proportion-adjustable automobile fluid matching control system and a control method thereof. The proportion-adjustable automobile fluid matching control system comprises a purified water supply tank, a purified water supplement and matching pipeline, a basic fluid supply tank, a basic fluid supplement and matching pipeline, a fluid storage tank and a cleaning fluid filling discharge pipeline, wherein the purified water supply tank is connected to the purified water supplement and matching pipeline and can supply the purified water supplement and matching pipeline with purified water; the purified water supplement and matching pipeline is connected to the fluid storage tank and can convey the purified water to the fluid storage tank; the basic fluid supply tank is connected to the basic fluid supplement and matching pipeline and can supply the basic fluid supplement and matching pipeline with basic fluid; the basic fluid supplement and matching pipeline is connected to the fluid storage bank and can convey basic fluid to the fluid storage tank; and the fluid storage tank is connected to the cleaning fluid filling discharge pipeline and can supply the cleaning fluid filling discharge pipeline with mixed fluid of the basic fluid and the purified water. The matching accuracy is high, bubbles can not be produced in a filling process, and the problems of poor matching accuracy of the basic fluid and the purified water during practical production, high manufacturing and maintenance costs of equipment and unsatisfactory product quality during in practical operation and filling processes are solved.

Description

technical field [0001] The invention relates to an adjustable-proportion automobile fluid proportioning control system and a control method thereof. Background technique [0002] In the current automobile production process, the cleaning fluid and antifreeze filling method of the automobile production line is to mix the cleaning fluid stock solution or antifreeze stock solution (hereinafter referred to as stock solution) and pure water in a certain proportion and then inject it into the automobile system pipeline. middle. [0003] At present, the filling of automobile cleaning fluid and antifreeze is carried out online on the production line. The equipment is pre-programmed by PLC, the flow of two liquids is monitored by a flow meter, and the two liquids are filled into the vehicle system according to the preset ratio. [0004] The above-mentioned filling method mainly has the following defects: 1. Since the accuracy of the liquid flowmeter will decrease with the increase ...
