Preparation device and method of fully-synthetic rail transit gear oil

Abstract

The invention discloses a preparation device and method of fully-synthetic rail transit gear oil, and relates to the technical field of gear oil preparation. The preparation device comprises a tank body, wherein the tank body comprises an outer tank and an inner tank, a heating pipe is arranged on the outer surface of the inner tank corresponding to a cavity, a liquid collecting box is arranged on the upper surface of the tank body, a first motor is fixedly installed on the upper surface of the liquid collecting box, a liquid outlet hole is formed in the position, corresponding to the liquid collecting box, of a rotating shaft, a first liquid pumping mechanism is arranged on the left side face of the liquid collecting box, three filtering mechanisms are sequentially arranged between the inner walls of the inner tank from top to bottom, and the upper surface of an evaporation box communicates with the heating pipe through an air outlet pipe. According to the preparation device, filtering effect is better, filtered impurities can be cleaned without shutdown, and production efficiency is improved; the inner tank is heated through discharged evaporated water, condensation of base oil is effectively avoided, and normal flowing of the base oil is ensured; and discharged steam can be purified, so the use of the device is more environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of gear oil preparation, in particular to a preparation device and method for fully synthetic rail transit gear oil. Background technique [0002] Gear oil is an important lubricating oil prepared mainly from petroleum lubricating oil base oil or synthetic lubricating oil, with the addition of extreme pressure antiwear agents and oily agents. Used in various gear transmissions to prevent tooth surface wear, abrasion, sintering, etc., prolong its service life and improve transmission efficiency. Gear oil should have good anti-wear, load resistance and suitable viscosity. In addition, it should also have good thermal oxidation stability, anti-foaming performance, water separation performance and anti-rust performance. In the process of gear oil processing and production, gear Oil will contain water and particles. In order to make the mechanical equipment run better and prevent the wear and tear of the mechani...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a preparation device and method for a fully synthetic rail transit gear oil, which has a better filtering effect, can clean the filtered impurities without stopping the machine, avoids the condensation of the base oil, and ensures the normal flow of the base oil. The advantage of purifying the discharged water vapor is to solve the problem that the water in the gear oil cannot be filtered, and the filtered impurities need to be shut down to clean up, and the water discharged by evaporation is directly discharged into the air, causing environmental pollution, and a large amount of heat in the water is wasted , the problem that the base oil cannot be heated
