Jiangxi Bagu Lubricating Oil Technology Co., Ltd. is a professional manufacturer of anti-wear hydraulic oils. This series of products is formulated with world patented technology—refined paraffin base oil through isomer dewaxing and supplemented with a variety of high-performance additives. Its quality exceeds international L-HM quality standards and the stringent requirements of hydraulic systems—German DIN 5124 PART 2-HLP grade, making it a long-life super anti-wear hydraulic oil.
Key Benefits: 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 extended periods, providing a long service life for hydraulic pumps and reducing maintenance frequency. 2. Stable Hydraulic System Pressure: Excellent anti-foaming and air release properties better meet the circulation requirements of lubricating oil, ensuring accurate power transmission, minimizing micro-vibrations, and avoiding surface wear due to lubricating film defects. 3. Excellent Anti-Emulsifying and Hydrolysis Stability: Allows for rapid water separation, making it suitable for the lubrication of hydraulic equipment operating in humid conditions. 4. Excellent Rust and Corrosion Protection: Provides surface protection for bearings, circulating pipelines, and oil tanks, preventing rust or corrosion, with zero weight loss on copper sheets, suitable for use in impeller pumps or steel-copper friction pairs in axial plunger pumps. 5. Long Service Life: Excellent oxidation stability ensures no oil sludge under long-term high-temperature operation, thus preventing filter blockage and better protecting the system's cleanliness and smooth operation. Mainly used for heavy-duty, high-temperature, and high-pressure hydraulic systems, widely applied in large-scale injection molding machines, forming machines, die casting machines, and high-tonnage press brakes, as well as in impeller pumps and plunger pumps with steel-copper friction pairs.
Basics of Industrial Lubricants
There are lubricants based on base oils, including hydraulic oils, gear oils, turbine oils, compressor oils, refrigerating oils, transformer oils, vacuum pump oils, bearing oils, metalworking oils (liquids), rust-proofing lubricants, cylinder oils, heat treatment oils, and thermal oils, among others. Additionally, lubricating greases with thickeners are included. Industrial lubricant users span various industries, typically requiring a wide variety of products in large quantities. The choice is not solely based on product price but also on quality and technical specifications, as well as the quality of technical services. Therefore, technical marketing of industrial lubricants is of utmost importance.
The machinery and equipment configurations are relatively concentrated, and companies that use industrial lubricants. Therefore, targeted technical seminars are more necessary. This is also the primary form of pre-sales technical service.
Hydraulic oil, as a medium for energy transmission, transmits power in hydraulic drive systems, reduces friction, isolates worn surfaces, suspends pollutants, controls component oxidation, and serves as a coolant. Various hydraulic systems have different types of structures and operating conditions. To meet the requirements of various systems, hydraulic oil must possess certain properties, such as viscosity, viscosity index, relative density, wear resistance, low-temperature properties, acid value, flash point, oxidation stability, emulsification resistance, hydrolysis stability, foaming, air release, shear stability, corrosion resistance, and filterability. According to GB11118.1-94, hydraulic oil is categorized by composition and application into the following types, each with different viscosity grades.
HL hydraulic oil is formulated from highly refined, neutral base oil with antioxidant and rust inhibitor additives for general machine tool hydraulic equipment. It is designed to reduce wear on components, lower temperature rise, and prevent rust. HM hydraulic oil is made from highly refined base oil with a viscosity index greater than 95, combined with antioxidants, rust inhibitors, and anti-wear agents, offering excellent anti-wear properties suitable for high-speed, high-pressure hydraulic systems.
Industrial Lubricant Usage: Problems and Solutions I. Hydraulic Oil Issues and Solutions
What are the causes of hydraulic oil particle contamination? What are the hazards? What are the prevention methods?
Powder 1 Cause: The reasons for hydraulic oil particle contamination are twofold: one is from external introduction, and the other is generated during the working process. 1 Dust from the atmosphere is introduced through the oil tank breathing hole, and 1 metal particles are produced due to wear on moving parts.
2 Sludge and sediments resulting from chemical changes of hydraulic oil during transportation and storage 3 Presence of hydraulic system components
Clog Filters, 2 Hazards caused by 3 Incompatibility between Seals, Gaskets, and Hydraulic Oil: A Adhesion. Servo Valve: B Increase wear on pumps and moving parts; C Accelerate oil aging and degradation; D Clog suction coarse filter, causing pump cavitation. 3 Prevention Methods: A Ensure oil tank is sealed and dust-proof, or install breathing holes with air filters; B Prevent dust and water during the storage and transportation of waste oil; C Install a filter in the system to remove impurities in a timely manner, preferably with an indicator filter, and install a magnetic separator at the bottom of the oil tank; D Install and regularly inspect and clean the coarse filter of the pump intake; E Add a protective cover to the cylinder and pushrod sealing area, or use blowing to prevent dust.
But there's a significant difference in types. Can two mineral hydraulic oils with the same viscosity be freely interchanged for systems requiring abrasion-resistant hydraulic oil? No. Although they have the same viscosity, it's absolutely not permissible to substitute L-HH or L-HL oils, as doing so would lead to premature failure of equipment oil pumps and operational malfunctions. Similarly, the L-HV and L-HS oils required for hydraulic systems in cold regions cannot be replaced with oils of the same viscosity grade, L-HM, as this would cause difficulties in cold starting and other issues.
