低温液压油,低温液压油根据低温性能的优劣和抗磨性能的高低,又分为普通低温液压油和寒区低温抗磨液压油,可用于北方寒季,也可全国四季通用。
According to the low temperature performance and anti-wear performance, low temperature hydraulic oil can be divided into ordinary low temperature hydraulic oil and low temperature anti-wear hydraulic oil in cold region. It can be used in cold season in North China and in four seasons in China.
液压油也称为抗磨液压油,它具有优良的抗氧化安定性、水解安定性和热稳定性,以抵抗空气、水分和高温、高压等,有效保护油泵,提高其延长使用寿命;抗磨液压油的应用十分广泛。
Hydraulic oil, also known as anti-wear hydraulic oil, has excellent anti-oxidation stability, hydrolysis stability and thermal stability to resist air, moisture, high temperature and high pressure, effectively protect the oil pump and prolong its service life; Antiwear hydraulic oil is widely used.
抗磨液压油的质量要求:
Quality requirements of anti-wear hydraulic oil:
1、良好的极压抗磨性,以 油泵、液压马达、控制阀和油缸中的摩擦副在高压、高速苛刻条件下得到正常的润滑,减少磨损;
1. Good extreme pressure and anti-wear performance, the friction pairs in oil pump, hydraulic motor, control valve and oil cylinder can be lubricated normally under high pressure, high speed and harsh conditions, so as to reduce wear;

2、优良的抗氧化安定性、水解安定性和热稳定性,以抵抗空气、水分和高温、高压等因素的影响或作用,使其不易老化变质,延长使用寿命;
2. Excellent antioxidant stability, hydrolysis stability and thermal stability to resist the influence or action of air, moisture, high temperature, high pressure and other factors, so that it is not easy to aging and deterioration, prolong its service life;
3、合适的粘度和良好的粘温性能,以 液压元件在工作压力和工作温度发生变化的条件下得到良好润滑、冷却和密封;
3. With proper viscosity and good viscosity temperature performance, the hydraulic components can be well lubricated, cooled and sealed when the working pressure and temperature change;        
4、良好的防锈性,以防止金属表面锈蚀。
4. Good rust resistance to prevent metal surface from rusting.
5、良好的抗乳化性,能与混入油中的水分迅速分离,以免形成乳化液,引起液压系统的金属材质锈蚀和降低使用性能;
5. Good demulsibility, can be mixed with the water in the oil quickly separated, so as to avoid the formation of emulsion, causing the metal corrosion of the hydraulic system and reduce the performance;
6、良好的抗泡性和空气释放值,以 在运转中受到机械剧烈搅拌的条件下产生的泡沫能迅速消失;并能将混入油中的空气在较短时间内释放出来,以实现准确、灵敏、平稳地传递静压;
6, good foam resistance and air release value, so that the foam produced by mechanical stirring will disappear quickly. It can release the air mixed in the oil in a short time to realize accurate, sensitive and stable static pressure transmission;
