Industrial lubricants mainly hydraulic oil, gear oil, turbine oil, compressor oil, refrigeration oil, transformer oil, vacuum pump oil, bearing oil, metal processing oil (liquid) oil, anti-rust oil, cylinder oil, heat treatment and heat conduction oil, etc.In addition, there are oil as base oil and grease with thickener added.Industrial lubricants user is enterprise from all walks of life, the use of the general variety, large dosage, not only depends on the price of the product, but also depends on the quality of the product and the technical features, but also depends on how well technical service.Therefore, industrial lubricants technology marketing is more important.Use of industrial lubricating oil companies, machinery and equipment in the configuration is relatively concentrated, so have a purpose, a targeted technical exchange more necessary.This is also the main form of pre-sale technical services.Industrial lubricating oil is the basic performance and the main selection principles of viscosity, therefore, must give priority to.GB/T3141-94 is industrial liquid lubricant ISO viscosity classification, equivalent adopt international standard ISO3448-1992 "industrial liquid lubricant - ISO viscosity classification".Generally said, in the speed, load and temperature is not high, under the condition of use of the viscosity of lubricating oil;In high load, low speed and higher temperature conditions, selection of high viscosity lubricating oil or add lubricating oil extreme pressure antiwear agent;At low load, high speed and low temperature conditions, choose low viscosity lubricating oil;In a wide range of high and low temperature, light load and high speed, and there are other special requirements, under the condition of choosing synthetic lubricantsThe basic performance and the main selection principles of the grease is cone into the degree, to cone into the degrees to divide the grease consistency level.Therefore, should introduce to the users.Cone into the degree of work is all sorts of commonly used control grease consistency index, applied to the performance and the grease of grease into the spot index of degree of hardness and softness.- j, t * * Y P7 K;J said, commonly use the bearing of the grease on the high load, low speed, small grease should choose cone into the degrees.Instead of small load, high speed, be about to choose large grease cone into the degrees.In a wide range of high and low temperature, light load, high speed and low temperature is very low, and there are other special requirements, should choose synthetic grease.Industrial lubricants category, more complex, technical performance have different characteristics, involving technology is extensive, and the hydraulic oil is the most industrial lubricating oil consumption of large varieties, tried to breed for example brief explanation.In the hydraulic transmission system, as the hydraulic oil of the energy transfer medium can be transmitted power, reduce friction, the partition of wear surface, suspended pollutant, oxidation control element, and has a cooling effect.All kinds of hydraulic system with different kinds of structure and conditions of use.In order to meet the requirements of all kinds of system, the hydraulic oil must possess certain properties, such as, viscosity, viscosity index, relative density, abrasion resistance, low temperature resistance, acid value, flash point, oxidation stability, emulsification, hydrolytic stability, foamability and air release, shear stability, anti-rust property and filterability.According to the hydraulic oil GB11118.1-94 in terms of the use of composition is divided into the following varieties, each species have different viscosity level.HL hydraulic oil is higher neutral base oil refining depth add antioxidant and anti-rust additives, used for general machine tool hydraulic equipment, in order to reduce the wear parts, reduce the temperature, prevent rust.HM depth of hydraulic oil is refined high viscosity index greater than 95 neutral base oil add antioxidant, corrosion inhibitor, and anti-wear agent, therefore, its abrasion resistance is good, can be used in high speed, high pressure hydraulic system.HG hydraulic oil is based on HM hydraulic oil to join the fight stick-slip additive agent (oily or anti-friction), in addition to good antioxidant, antirust and abrasion resistance, but also has excellent resistance to stick - smoothness, used in the hydraulic system and share of machine tool guideway lubrication system, make the guide under the low speed vibration and discontinuous sliding (stick - slip) to the minimum, but not for high pressure hydraulic system.HV hydraulic oil viscosity index greater than 130 base oil, add antioxidant, antirust, anti-wear, viscosity index improver and coagulant, can be used in cold region field and work under the bad environment of hydraulic equipment.Is closing, hydraulic oil, hydraulic oil HS with good performance at low temperature of alpha olefin synthetic oil as base oil, add the HV hydraulic oil with various additives, made of pour point is not higher than - 45 ℃ low temperature hydraulic oil, suitable for cold region field and work under the bad environment of hydraulic equipment.
