The excellent oxidation resistance of 1 and 46 # hydraulic oils prolongs the replacement cycle of oil products and oil filters. Anti-wear performance and excellent oil film strength make the equipment play an outstanding role, which not only has fewer faults, but also helps to improve productivity. Carefully prepared anti-emulsification performance enables it to work as usual in a system with a small amount of water pollution, but it can be separated immediately when the water content is high.
2.68 hydraulic oil is composed of HM hydraulic oil and oiliness agent or antifriction agent. The oil not only has excellent rust prevention, oxidation resistance and wear resistance, but also has excellent stick-slip resistance. This product is mainly suitable for various lubrication systems of machine tool hydraulic and guide rail, or machine tool guide rail lubrication system and machine tool hydraulic system.
Specific differences between No.46 hydraulic oil and No.68 hydraulic oil:
1, kinematic viscosity (40℃), mm2/s: HM46 is 46, HM68 is 68.
2. Viscosity index: HM46 is 10 1 and HM68 is 106.
3. Flash point (opening), ℃: HM46 is 202, HM68 is 2 10.
4. Copper corrosion (100℃, 3h), grade: HM46 1, HM68 1.
5. Pour point, ℃: HM46 is-12, HM68 is-1 1.
6. Corrosion test: HM46 does not rust, and HM68 does not rust.
7. Emulsifiability (40-37-3 ml), min: HM46 is 10, and HM68 is 15.
8. Pollution degree (NAS 1638), grade: HM46 is 7, and HM68 is 7.
Extended data
System suitable for hydraulic oil application
1. industrial hydraulic system: hydraulic oil is suitable for various types of hydraulic systems in manufacturing and industry.
2. Mobile hydraulic transmission system: Hydraulic oil can be effectively used for mobile hydraulic equipment such as excavators and cranes.
3. Marine hydraulic system: It is suitable for the marine hydraulic system recommended to use ISO HM hydraulic oil.
Suitable for hydraulic oil applications.
1, hydraulic systems that are greatly affected by sediment deposition, such as precision numerical control machinery, especially hydraulic systems that use low clearance servo valves;
2. Inevitable application of a small amount of water;
3. When using traditional products, there will be applications that form sludge and deposits;
4. Systems with gears and bearings;
5, need high bearing capacity and wear protection system;
6. Anti-corrosion protection of thin oil film is an important application, such as a small amount of water is inevitable;
7. Machines that use a large number of different metals to make parts;
