Tongchuan hydraulic oil _ Wei Xiai _VXI-32 # hydraulic oil

 In the selection of hydraulic equipment used hydraulic oil, start with a few aspects of the work pressure, temperature, work environment, hydraulic systems and components and material structure, economy, etc. into account and determine the working environment and working conditions to select varieties based hydraulic oil . Environmental factors: on the ground, underground, indoor, outdoor, coastal, cold regions, high temperature, fire. Use conditions: pump type, pressure, temperature, material, sealing material, the running time. Oil Properties: physical and chemical performance characteristics. Economy: the use of time, oil change, price. Working pressure lubrication mainly abrasion hydraulic oil that request. Hydraulic components, especially the high-pressure system in the boundary lubrication pump in the friction, due to the positive pressures, high speed leaving the tribological conditions are harsh VXI-46 # hydraulic oil, lubricating properties must be selected that abrasion resistance, extreme HM excellent oil pressure. By hydraulic system and pump working pressure of hydraulic oil pressure 16MPa with L-HM, L-HV hydraulic oil. Working pressure of the hydraulic system is typically its main pump maximum pressure rating or flag. Operating temperature means the hydraulic system hydraulic oil temperature at work VXI-32 hydraulic oil, which mainly viscosity-temperature resistance and thermal stability of hydraulic oil requested operating temperature -10-90 ℃ with L-HH, L-HL , L-HM hydraulic oil, lower than -10 ℃ with L-HV, L-HS, operating temperature> 90 ℃ selection of high quality L-HM, L-HV, L-HS. Ambient temperature and operating temperature is generally the relationship: Hydraulic equipment in factory workshop, the normal operating temperature higher than the ambient temperature 15-25 ℃; hydraulic equipment outdoors in temperate and high 25-38 ℃; in the tropical outdoor sunlight, high 40-50 ℃ VXI-46 hydraulic oil 1. Use the garbage truck hydraulic oil in the hydraulic system requirements for working oil has a dual role, first as an energy transfer medium, hydraulic oil, and second, as a lubricant lubricate moving parts of the work surface, and therefore oil performance liquid will directly affect the performance of the hydraulic system, such as reliability, sensitivity, stability, efficiency and service life. Oil hydraulic system should meet the following general requirements: appropriate viscosity, good viscosity-temperature characteristics in the temperature range of VXI-68 hydraulic oil, the oil viscosity changes with temperature as low as possible; good lubricating properties, strong antirust ability ; pure texture, fewer impurities, does not contain corrosive substances, in order to avoid erosion and sealing parts; metal and seals have good compatibility; good oxidation stability, long-term non-perishable, oxidative deterioration of oil will produce jelly product, thus clogging filters and valves damping orifice; anti-foam properties and good resistance to emulsification, high flash point and fire point, pour point and low freezing point. For specific hydraulic drive system, depending on the circumstances you need to highlight certain aspects of the use of performance requirements. 2. Many varieties of hydraulic oil hydraulic oil varieties, mainly divided into three types: mineral oil-emulsion type and synthetic. According to the relevant national standards, lubricants and related products are Class l, where h is the hydraulic system with fluid group (not include automobile brake fluid and aviation hydraulic fluid), and then further classified according to the composition and characteristics of the product, such as a specific product can be named L-HM32 (where 32 represents the annual level of the liquid). Sprinkler hydraulic drive system commonly used for mineral oil based hydraulic oil. Mineral oil based hydraulic oil lubrication and rust resistance, a wide range of viscosity grades, and thus in the hydraulic system is widely used. According to statistics, there are currently more than 90% of the hydraulic system mineral oil hydraulic oil as the working medium.
