China Yongchang Hydraulic Machinery Co., Ltd. is a manufacturer of high quality hydraulic motors, and the selection of hydraulic oil is more stringent.
In general, the plunger hydraulic motor uses No. 46 anti-wear hydraulic oil.
Anti-wear hydraulic oil hydraulic oil (HM hydraulic oil) is developed from rust-proof and anti-oxygen hydraulic oil. It has alkaline high zinc, alkaline low zinc, neutral high zinc and ashless. The series products are divided into four grades of 22, 32, 46 and 68 according to the 40'C kinematic viscosity.
Quality requirements :
(l) Proper viscosity and good viscosity-temperature performance to ensure that the hydraulic components are well lubricated, cooled and sealed under varying operating and operating temperatures.
(2) Good extreme pressure and wear resistance to ensure that the friction pair in the oil pump, hydraulic motor, control valve and cylinder is normally lubricated under high pressure and high speed and severe conditions, reducing wear.
(3) Excellent anti-oxidation stability, hydrolysis stability and thermal stability, to resist the influence or effect of air, moisture and high temperature, high pressure and other factors, so that it is not easy to aging and deteriorate, and prolong the service life.
(4) Good anti-foaming and air release values to ensure that the foam generated under the condition of mechanical and vigorous agitation in operation can disappear rapidly; and the air mixed into the oil can be released in a short time to achieve Accurate, sensitive and smooth transmission of static pressure.
(5) Good demulsibility, can be quickly separated from the water mixed into the oil, so as to avoid the formation of an emulsion, causing corrosion of the metal material of the hydraulic system and reducing the use performance.
(6) Good rust resistance to prevent corrosion of metal surfaces.
(1) To keep the hydraulic system clean, remove the sludge and metal shavings in the tank in time.
(2) Change the oil according to the oil change reference index. When changing the oil, clean all parts of the equipment to avoid impurities and other mixed into the oil, which will affect the use effect.
(3) When storing and using, the container and the refueling tool must be cleaned to prevent the oil from being contaminated.
(4) The oil is mainly applied to the hydraulic oil pump of the steel-steel friction pair. When using hydraulic oil pumps for friction materials of other materials, it is necessary to have the oil pump load limit applicable to the product recommended by the oil pump manufacturer or the oil supply unit.
