Automatic water quality monitoring and dosing system for circulating cooling water of diesel engine

Abstract

An automatic water quality monitoring and dosing system for circulating cooling water of a diesel engine comprises a circulating filtration loop, a water quality monitoring loop, a dosing device and an automatic control display device, wherein the water quality monitoring loop is used for carrying out real-time water quality detection on sampled cooling water and conveying water quality monitoringdata to the automatic control display device; the automatic control display device compares the water quality monitoring data with stored correlation curve relation data of water quality index parameters and the agent concentration in the cooling water; when the agent concentration of in the cooling water is lower than the correlation curve relation data, the automatic control display device controls the dosing device to inject a rust-proof maintenance agent into the circulating filtration loop, and the automatic agent adding function is achieved; and when the agent concentration reaches thepreset correlation curve relation data, the automatic control display device controls the dosing device to stop working, so that the water quality index of the circulating cooling water of the dieselengine is stably controlled and kept in a normal range. According to the invention, automatic monitoring and maintenance of the diesel engine circulating cooling water system are realized, the reliability of the cooling water circulating system is improved, and the working intensity is reduced.

Description

technical field [0001] The invention relates to an antirust and maintenance process for diesel engines, in particular to an automatic water quality monitoring and dosing system for circulating cooling water of diesel engines, and belongs to the technical field of marine diesel engines. Background technique [0002] The function of the diesel engine circulating cooling water system is mainly to cool the combustion chamber components of the main engine, which is an indispensable part of the normal operation of the diesel engine. The average temperature of the cooling water of the main engine is about 80°C, and the pressure can reach up to 5-6bar. The material of the cooling water pipe is carbon steel. Since the cooling water system has been in a high-temperature and high-pressure working environment for a long time, the main engine is not running all the time. , when the main engine is in the process of starting and stopping, the water pipes of the cooling water system are not...

AI Technical Summary

Problems solved by technology

However, the existing diesel engine circulating cooling water system lacks real-time monitoring of water quality, and dosing is also done manually, so it is impossible to grasp the changes in water quality and add anti-rust maintenance agents in time to achieve automatic monitoring and maintenance of diesel engine circulating cooling water system. Purpose, how to timely and effectively monitor and maintain the diesel engine cooling water system has become a long-standing problem in the industry
