RESEARCH AND DEVELOPMENT OF INSTALLATIONS FOR COOLANT OPERATION SYSTEMS AND METHODS FOR CALCULATING THEIR PARAMETERS

Abstract

The regularities of the process of filtration of technological liquids through porous materials are investigated and highly efficient installations for the operation of lubricating and cooling liquids are developed. It has been established that during operation, liquids are continuously and intensively contaminated with solid particles of metalworking. To restore their properties, process fluids are cleaned of mechanical impurities. The most widely used methods of purifying process fluids are filtration. The use of filtration for the purification of process liquids is the most effective, since filtration through a layer of porous materials can achieve complete removal of solid particles from liquids.

The purpose of this work is to study the installations for cleaning lubricating and cooling liquids in mechanical workshops and to develop new highly efficient equipment for cleaning coolant of metal-cutting machines and methods for calculating their parameters.

As a result of the implementation of the developments for coolant operation systems and methods for calculating their parameters, the service life of coolant in the technological chain was increased by 3%, the durability of cutting tools was increased by 6-8%, and the quality of machined surfaces was improved. The use of the proposed highly efficient developments of filtering equipment provides complete clarification of coolant and deep removal of solid particles of valuable secondary raw materials of metalworking, in particular for powder metallurgy, creates conditions for the organisation of waste-free production, increases the level of environmental safety at the coolant operation site.
