Problems solved by technology

However, the carcinogens (naphthenic aromatic hydrocarbons, benzopyrene, etc.) released by oil products at high temperatures, the pollution and energy consumption generated during the use of such oil products not only cause harm to human health, but also consume a lot of energy when heating oil products. A large amount of electric energy; and the relatively high cost of the original oil for the powertrain, the oil is easily oxidized under high temperature, and the service life will be shortened, which also increases the production cost of the enterprise

Abstract

The invention discloses a vehicle oil pump running-in oil and a preparation method thereof. Its raw materials are 90-99% blended base oil, 0.1-9% low-zinc extreme pressure anti-wear agent, 0.1-1.5% % of phenolic antioxidants, 0.02% to 0.1% of demulsifiers and 0.00001 to 0.00002% of silicone antifoaming agents. The method first adds phenolic antioxidants to the blended base oil, mixes at 70-80°C for 10-15 minutes; heats up to 80-90°C, then adds low-zinc extreme pressure anti-wear agent and mixes for 10-20 minutes; heats up to 100-120°C, then add anti-emulsifier and mix for 5-10 minutes; finally add silicone anti-foaming agent and mix for 15-20 minutes. The invention controls the oil temperature of the oil pump in the factory flow performance test within 50°C, thereby saving the power consumption caused by heating, eliminating the emission of harmful gases, and ensuring the health of employees.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to a vehicle oil pump running-in oil and a preparation method thereof. Background technique [0002] The function of the vehicle oil pump is to increase the pressure of the lubricating oil, so that the lubricating oil is delivered to the various lubricating oil passages of the car and the friction surfaces of the moving parts at a certain pressure, so as to ensure continuous, stable and reliable lubrication. Therefore, under the condition of constant speed and pressure of the oil pump, the stability of the flow performance of the oil pump will determine the quality of the lubrication state of various parts of the automobile. [0003] In order to ensure that the oil pump products meet the needs of use, each oil pump must test the flow rate of the oil pump at the rated temperature, speed and pressure before leaving the factory to determine the performance of the oil pump. [0004] The ...
