Problems solved by technology

Among them, the temperature of superheated steam can reach 320-400°C, and the pressure can reach 3920kPa, which will denature the lubricating oil film. Under the repeated washing of steam and condensed water, the oil film will be thinned and oxidized, and the cylinder is prone to corrosion and stress damage, and the seal will fail.

Abstract

The invention discloses a mineral oil type steam cylinder oil composition and a preparation method and application thereof. The composition consists of the following raw materials in parts by mass: 70-80 parts of mineral oil type steam cylinder oil, 6-8 parts of sphalerite, 3-5 parts of tremolite, 1-3 parts of lanthanum, 1-2 parts of ethenyl triethoxysilane and 1-2 parts of lithium hydroxystearate. The prepared mineral oil type steam cylinder oil composition can form a super anti-corrosion metal ceramic hard wear-resistant layer on the surface of a steam cylinder so as to keep smooth motion of the steam cylinder, reduce the fault rate and prolong the service life of the steam cylinder by over twice; moreover, the consumption of a lubricating material can be saved, and a green environment-friendly effect is realized. The mineral oil type steam cylinder oil composition has the advantages of easily-available raw materials, scientific formula, simple preparation process, low cost and good performance, and is particularly suitable for the cylinders, such as a lubricating steam locomotive, a steam ship, a steam pump and a steam hammer in direct contact with steam, and also can be applied to low-speed heavy-load machinery.

Description

technical field [0001] The invention relates to a mineral oil-type steam cylinder oil composition, in particular to a cylinder suitable for lubricating steam locomotives, steam ships, steam pumps, steam hammers, etc., which are directly in contact with steam, and can also be used for low-speed and heavy-duty machinery. technology field. Background technique [0002] Steam cylinder oil is lubricating oil for reciprocating steam engine cylinders, pistons, valves, and sometimes for crosshead connecting rods and slide rail guides. Steam locomotives, steam ships, steam pumps, steam hammers, etc. widely use steam engines as power sources. [0003] The working characteristics of the steam engine are high temperature, heavy load, direct contact with steam, and being cleaned by it. Among them, the temperature of superheated steam can reach 320-400 ℃, and the pressure can reach 3920kPa, which will denature the lubricating oil film. Under the repeated washing of steam and condensed w...
