Jiangxi Bagu Lubricating Oil Technology Co., Ltd. is a professional manufacturer of anti-wear hydraulic oils. Our product series is formulated using world patented technology—refined paraffin-based base oil through isomer dewaxing, and supplemented with a variety of high-performance additives. Its quality exceeds international L-HM grade quality standards and the stringent requirements of hydraulic systems—German DIN 5124 PART 2 HLP level, making it a long-life super anti-wear hydraulic oil.
Key Advantages: 1. Reduced Equipment Maintenance Costs: Contains high-efficiency extreme pressure anti-wear additives that effectively control gear and bearing wear under heavy load conditions for long-term use, providing a longer service life for hydraulic pumps and reducing the frequency of maintenance. 2. Stable Hydraulic System Pressure: Excellent anti-foaming and air release properties better meet the lubricant circulation requirements, ensuring accurate power transmission and minimizing micro-vibration, thereby avoiding the possibility of surface wear due to lubrication film defects. 3. Excellent Anti-Emulsification and Hydrolytic Stability: Enables rapid water separation, making it suitable for lubricating hydraulic equipment operating in damp conditions. 4. Excellent Corrosion and Rust Protection: Provides full protection for bearings, circulating pipelines, and oil tanks, preventing rust or corrosion, with zero copper weight loss, suitable for use in vane pumps or axial piston pumps with steel-copper friction pairs. 5. Long Service Life: Excellent oxidation stability ensures no oil sludge formation under long-term high-temperature operation, thus preventing filter clogging and better protecting the system's cleanliness and smooth operation. Mainly used for heavy-duty, high-temperature, and high-pressure hydraulic systems, widely used in large-scale injection molding machines, forming machines, die-casting machines, and high-tonnage stamping presses, as well as vane pumps and piston pumps with steel-copper friction pairs.
Hydraulic oil specifications, performance, and applications:
This type of oil comes in various varieties, including HHHL, HLM, HRH, and V-grade HG hydraulic oils, all of which fall under the GB/T 7631.2-87 classification as mineral-based hydraulic oils. Their usage accounts for over 85% of the total hydraulic oil volume, and the hydraulic oils commonly used in automotive and construction machinery hydraulic systems are mostly from this category.
The following sections introduce their specifications, performance, and applications.
HH Hydraulic Oil
HH Hydraulic Oil is a mineral oil that contains no additives. Although it has been categorized according to GB7631.2-87 standards, it is no longer used in hydraulic systems. This is due to its poor stability, tendency to foam, and short service life in hydraulic equipment.
HL Hydraulic Oil (also known as General-purpose Machine Tool Industrial Lubricating Oil)
HL hydraulic oil, enhanced with antioxidant and anti-rust additives, is available in six grades (152, 232, 246, 680, 100) based on a 40C kinematic viscosity. Grade l HL hydraulic oil is made from highly refined, neutral base oil.
Usage
Lubrication for bearing boxes, gearboxes, low-pressure circulation systems, or similar machinery circulation systems of various machine tools operating at temperatures above 0°C. This product can extend the service life by over twice that of mechanical oil. It boasts good compatibility with rubber seals, and HL hydraulic oil is primarily used where no special lubricant requirements are specified. Its maximum operating temperature is 80°C.
Quality Requirements
The temperature change should not affect the normal operation of the hydraulic system. It requires an appropriate viscosity and good viscosity-temperature properties. The oil's viscosity should be minimally affected by temperature changes.
Excellent rust and oxidation resistance.
It offers an ideal air release value, anti-foaming properties, water separation capabilities, and rubber sealing adaptability.
Quality Requirement for Abrasion-Resistant Hydraulic Oil
1. Excellent oxidation, hydrolysis, and thermal stability of the wear-resistant hydraulic oil, which resists the effects or actions of air, moisture, high temperatures, and high pressures, making it less prone to aging and deterioration, thereby extending its service life.
2. Excellent anti-foaming hydraulic oil has good anti-emulsifying properties, which can quickly separate from water mixed into the oil, preventing the formation of emulsion and thereby avoiding metal corrosion in the hydraulic system and reducing its performance.
3. Excellent anti-foaming properties and air release values ensure that foam generated under conditions of intense mechanical stirring during operation dissipates quickly; and that air mixed with oil is released in a shorter period of time, achieving accurate, sensitive, and stable transmission of static pressure.
4. Excellent extreme pressure anti-wear properties of the hydraulic oil ensure normal lubrication of friction pairs in oil pumps, hydraulic motors, control valves, and cylinders under high pressure and high-speed severe conditions, reducing wear.
5. Excellent anti-rust properties of the wear-resistant hydraulic oil to prevent rusting of metal surfaces.
6. Suitable viscosity and good viscosity-temperature properties of the anti-wear hydraulic oil ensure excellent lubrication, cooling, and sealing for hydraulic components under varying working pressures and temperatures.
