赣州章贡赣江街道美孚液压油-V达导轨油销售液压技术的发展趋势，以工程机械为例，主要向高压化、高速化、小型化、机电一体化，以及提高产品清洁度，控制系统污染等方向发展。由于工程机械大多数是野外作业，液压系统经常受到尘埃、高低温、振动、风雪等侵袭，造成液压油污染、引发故障。根据国内外统计资料，液压和润滑系统中70%以上的故障是由于工作介质（液压油）的污染造成的。我国矿物型和合成烃型液压油的产品标准是GB11118.1-94，包括HL、HM、HG、HV、HS五个的技术规格。液压油粘度等级分为10、15、22、32、46、68、100、150等八种，常用的粘度等级为32、46、68三种。The development trend of hydraulic technology, taking construction machinery as an example, is mainly towards high pressure, high speed, miniaturization, mechatronics engineering, as well as improving product cleanliness and controlling system pollution. Because most of construction machinery is field work, hydraulic system is often attacked by dust, high and low temperature, vibration, wind and snow, causing hydraulic oil pollution, causing failure. According to domestic and foreign statistical data, more than 70% of the faults in hydraulic and lubrication systems are caused by the contamination of working medium (hydraulic oil) . The product standard of mineral and synthetic hydrocarbon hydraulic oil in our country is GB11118.1 -94, including HL, HM, HG, HV and HS. Hydraulic oil viscosity grade is divided into 10,15,22,32,46,68,100,150 eight, commonly used viscosity grade for 32,46,68 three.
