A kind of antirust gear oil

Abstract

The present invention disclosed a rust-proof gear oil, which is made of raw materials of the following weights: 15-22 sodium silicate, 10-17 copies of mineral hybrid oil, 2.5-7.3 copies of diocyl acid anhydride, three copies of the dilate.2.3-6.5 parts of ethanlamine, 2.3-4.6 parts of ten-carbon dilate acid, and 1.2-6.3 parts of ethyleine tetraxyl acid.Compared with the existing gear oil, the present invention has good antioxidant anticorrosive, rust -proof, long oil replacement cycle, reducing waste oil, exhaust gas and particulate matter discharge, good biodegradability, lower prices than traditional lubricants are lower than traditional lubricants.The characteristics of; at the same time, the heavy load industrial gear can quickly form a wear -resistant, high temperature, and squeeze -resistant boundary lubricant film under high -speed, low -speed, heavy load, high torque or impact load., Blogen, Eclipse and other destruction phenomena to extend the service life of the heavy load industrial gear.

Description

technical field [0001] The invention relates to an antirust gear oil, which belongs to the field of industrial chemical industry. Background technique [0002] At present, external gear oil pumps at home and abroad, especially high-pressure gear oil pumps, mostly use cast iron shells and DU bearing structures. The DU bearings supporting the journals of the main and The sealing method of automatic axial clearance compensation is mainly based on completely isolating the high-pressure oil from the low-pressure bearing cavity. Even if the new DU bearing (carbon steel-based gear pump self-lubricating bearing) is lubricated by oil, the highest PV value reaches 60N / mm2·m / s, the maximum linear velocity V reaches 10m / s, and due to the insufficient amount of lubricating oil, the performance of DU bearings cannot be fully utilized, which will cause bearing ablation and damage or reduce the service life, resulting in the service life of the high-pressure gear pump short.

Problems solved by technology

[0002]At present, most of the external gear oil pumps at home and abroad, especially high-pressure gear oil pumps, adopt cast iron shells and DU bearing structures, and the DU bearings supporting the journals of the main and slave gear shafts It is an important part that determines the rated pressure and life of the gear pump. However, due to the sealing method of automatic axial clearance compensation, it is mainly to completely isolate the high-pressure oil from the low-pressure bearing chamber. Even if the new DU bearing (carbon steel-based gear pump self-lubricating Bearing) under the condition of oil lubrication, the highest PV value reaches 60N / mm2 m / s, and the maximum linear velocity V reaches 10m / s. Also due to insufficient lubricating oil, the performance of DU bearings cannot be fully utilized, making the bearing Destruction or reduced service life due to ablation, resulting in short service life of high pressure gear pumps
