Energy-saving oil temperature control system of machine tool

Abstract

The invention discloses an energy-saving oil temperature control system of a machine tool. The energy-saving oil temperature control system comprises a water tank, a heat exchanger, a control processing center, a control valve, a heat accumulation and exchange device, a temperature sensor, a frequency conversion motor and a water pump, wherein the temperature sensor is used for acquiring temperature of oil in an oil tank and transmitting a temperature signal to the control processing center; the control center receives the temperature signal, analyzes and processes the temperature signal and sends a corresponding control signal to control the motor and the valve to work; the heat exchanger is arranged into the oil in the oil tank and used for exchanging heat between water inside and outside a pipe and the oil; and the heat accumulation and exchange device is used for storing heat exchanged from the oil and supplying heat for preheating or heating the oil. The energy-saving oil temperature control system can effectively control the oil temperature of the machine tool, so that the usability of hydraulic oil of the machine tool is improved; furthermore, the heat exchanged from the oil can be recycled and reused; and the energy-saving oil temperature control system has the characteristic of saving energy.

Description

technical field [0001] The invention relates to the technical field of temperature control, and more specifically relates to an energy-saving oil temperature control system for machine tools. Background technique [0002] At present, as one of the main equipment of industrial production, the performance of the machine tool is getting more and more attention. The performance of the hydraulic system of the machine tool has an important influence on the performance of the machine tool, especially the control of the oil temperature. Kinematic viscosity and lubricity are highly influential and therefore important factors in the proper and efficient operation of the system. [0003] Oil temperature control is mainly divided into two aspects: heating and cooling. At present, the commonly used heating method is to place an electric heating tube in the oil tank. The defect of this control method is obvious. The electric heating rod method is easy to produce local overheating, which ...

AI Technical Summary

Problems solved by technology

At present, the commonly used heating method is to place an electric heating tube in the oil tank. The defect of this control method is obvious. The electric heating rod method is easy to produce local overheating, which will cause the oil to deteriorate and seriously affect the performance.

The main problem of energy loss is serious during cooling. A large amount of energy in the hydraulic system is converted into heat energy, which increases the temperature of the hydraulic oil. The common cooling method is to directly use cold air or cold water to take away the heat energy, so that the energy is lost in vain.
