Pao synthetic heavy load gear lubricant hpa product performance description
MEtalub-hpa products include vg150, vg220, vg320, vg460 series
Overview of products
Pao synthetic heavy load gear lubricant hpa is a high-end gear lubricant that is based on high-quality α-olefins (paos) and re-composed with multiple efficient functional additives. The product is designed to respond to heavy loads and severe conditions of gear transfer systems, which can provide excellent lubrication protection for equipment, effectively extend the service life of gears and reduce the cost of equipment maintenance, and is widely applied to heavy load gear boxes in the metallurgy, mine, engineering machinery, wind, electricity and cement industries。
Core performance advantages
(i) magnificent mucous properties
The hpa product has excellent adhesive properties based on the unique molecular structure of the pao base oil. It has a viscosity index of over 140, much higher than traditional mineral oils. In low-temperature environments, the fluids remain well liquid and can quickly reach the lubricants, effectively reduce dry friction at the time of start-up of the equipment and avoid wear and tear during the cold start-up phase; in high-temperature conditions, the viscosity of the fluids remains stable, forming sufficiently thick oil membranes to withstand heavy load shocks to the gear surface, preventing direct contact with metals resulting from the rupture of the film, and ensuring that the gear-carving system operates at a stable temperature range of -40°c to 120°c。
(ii) excellence in anti-extreme stress and wear resistance
Hpa products add highly effective ultra-pressure resistance additives to the extreme pressure and shock load conditions common in heavy load gear gear transfer. Through special chemical reactions, a strong, grinding chemical protective film is formed on the gear surface, which withstands up to 1800 n of exposure pressure and effectively resists such forms of wear and tear as viscos, bruises, and bruises. After testing the four-ball machine, its uncarded bite load (pb value) exceeds 1,000 n, the stowage load (pd value) can exceed 3000 n, and when used on heavy load equipment such as mine shredders, metal mills, etc., it can significantly reduce gear wear and tear and extend the useful life of gears by more than 30%。
(iii) excellent oxidation and long-term effectiveness
The pao base oil itself is highly resistant to oxidation, combined with efficient antioxidation additives in hpa products, which can effectively inhibit the oxidation of the fluid in high temperatures and oxygen environments. The oxidation of hpa products has increased by more than 50 per cent compared to traditional mineral oils, and sediments, such as oil sludge and charcoal, are not readily produced during long-term use, maintaining fluid cleanliness and reducing the frequency of filter congestion. Under normal conditions, the product can be refuelled for up to 8000-12000 hours, two to three times as much as conventional mineral oil, significantly reducing the cost of maintenance of the equipment and the time of shutdown。
(iv) good corrosion resistance
The hpa products are equipped with high-efficiency preservatives and preservatives, capable of forming a dense protective membrane on the surface of the gear metal, effectively insulating contact with the surface of the metal by corrosive media such as moisture, oxygen, acid, etc., and preventing corrosive problems such as corrosion in the gear. Even during moist environments or equipment shutdowns, the gear is provided with reliable protection against rust, avoiding loss of gear accuracy and reduced useful life due to rust. After testing the salt mist, the product can have a rust-resistant grade up to level 1 of the gb/t 11143 standard to meet the need for rust-resistant equipment in a bad environment。
(v) good sealed compatibility
Hpa products are well compatible with common rubber seals (e. G., butler rubber, fluorine, etc.) and do not lead to aging of seals, such as solubility, constriction, hardening, etc., during long-term use, to maintain the elasticity and sealing properties of the seals and to effectively prevent spills of oil. This feature reduces the fluid depletion and environmental pollution caused by the failure of the seal while reducing the risk of failure of the equipment caused by the oil spill and ensuring its stable operation。
Applicable scenes
Heavy load gear transfer systems: such as shredders in mine machinery, spherical gear boxes, roller gears in metallurgical equipment, loaders in engineering machinery, main speed retardators, etc。
Wide temperature range work: equipment for outdoor operation in cold areas (e. G., gear boxes for wind and electrical equipment), operating in high temperature environments (e. G., gearboxes for cement rotary kilns) can stabilize within -40°c to 120°c temperatures。
Long-term continuous operation equipment: for example, power generation equipment, gear transfer systems for paper-making equipment, which can reduce the time spent on equipment shut-downs and increase production efficiency through long-activated fuel cycles。
Use of vigilance
The product applies to closed gear transfer systems and not to open gear transfer。
Prior to use, gear boxes should be cleaned to ensure that they are free of impurities and old oil residues and avoid mixing with other types of lubricant, thus affecting product performance。
The appropriate hpa product should be selected according to the sticky level recommended in the equipment description to ensure that it matches the equipment condition。
Storage shall be sealed in cold, dry and ventilated areas to avoid direct sunlight and water intrusion, and the storage temperature shall not exceed 40°c。
