Problems solved by technology

Especially in the fields of water supply and drainage and agricultural engineering, aerospace and navigation engineering, which are in contact with water and the environment is humid, the existence of moisture can easily enter the lubrication system and cause equipment lubrication failure. There are more special requirements, and there is no special oil for centrifugal pumps. At present, the lubricating oil used for centrifugal pumps is mainly replaced by anti-wear hydraulic oil, and the quality index of anti-wear hydraulic oil itself cannot reach it at all. The special requirements of centrifugal pumps, anti-wear hydraulic oil requires rapid separation of moisture, while centrifugal pumps have less oil tanks and continuous operation cannot give enough time for the oil in the centrifugal pump to settle, so moisture will form in the lubrication system Uneven distribution, easy to damage the lubricating film, damage the lubrication system, wear equipment, and the entry of moisture will also cause damage to anti-foaming properties and rust of equipment

Abstract

The invention provides hydrophilic oil special for a centrifugal pump in outdoor and humid areas. The hydrophilic oil comprises the following components in percentage by weight: base oil and an additive, the addition amount of the additive is 3.075%-6.52% of that of the base oil, and the base oil at least comprises the following three components in percentage by weight: 75%-85% of polyether, 10%-15% of polyester, and 5%-10% of alcohol. The additive at least comprises five components: 0.2%-1% of an ashless wear-resistant rust-proof antioxidant multifunctional additive, 2%-5% of an HLB value regulator, 0.02%-0.8% of a high rust-proof additive, 0.005%-0.02% of a high water resistance composite anti-foaming agent and 0.05%-0.5% of a multifunctional anti-corrosion additive. The product can still well protect equipment under the condition that moisture enters the equipment, so that the equipment can maintain good lubrication and can still operate normally.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a hydrophilic type special oil for centrifugal pumps in outdoor and wet areas and a preparation method thereof. Background technique [0002] Centrifugal pumps are the most widely used of all kinds of water conservancy machinery, and are the most closely related to our daily life and production activities. In recent years, centrifugal pumps have been widely used in water supply and drainage, agricultural engineering, petroleum industry, aerospace and navigation The application in engineering is becoming more and more extensive, and its proportion is also increasing. Centrifugal pumps belong to the heart in the process of transporting raw materials. Once a failure occurs, irreparable losses will occur. Especially in the fields of water supply and drainage and agricultural engineering, aerospace and navigation engineering, which are in contact with water and t...
