Lubrication Grease Hose is a dedicated pipeline product designed for conveying oily media. Distinct from ordinary water pipes, air hoses and chemical hoses, its material toughness, inner wall sealing performance and oil infiltration resistance are developed around oil transportation requirements. It is mainly adapted to various oily lubricating media for industrial and mechanical equipment and is not applicable to water, chemical solvents, corrosive liquids and other media. The compatible media can be divided into core commonly used media and auxiliary compatible media, and there are clear restrictions on media application.
The core and most frequently conveyed media in daily application are various basic lubricating oils for equipment, which represent the main application scenarios of Lubrication Grease Hose. First of all, general machine lubricating oil with moderate viscosity and stable properties is widely adopted for daily lubrication and maintenance of machine tools, air compressors, conveying equipment and small general machinery, making it the most frequently transported medium by Lubrication Grease Hose. Next are hydraulic and lubricating dual-purpose oils, used in hydraulic equipment and oil pressure systems. They can transfer pressure and achieve component lubrication of equipment, matching the pipeline transportation demands of most medium and low-pressure hydraulic lubrication equipment. In addition, engine oil and gear oil are core compatible media, applied to oil supply for lubrication of construction machinery, agricultural machinery and transmission equipment. The hose can withstand long-term infiltration and cyclic scouring of such medium viscosity oils without material swelling or shedding.
Apart from basic lubricating oils, Lubrication Grease Hose can also adapt to various industrial auxiliary oily media to meet diversified equipment maintenance scenarios. The first category is anti-rust lubricating oil, widely used for anti-rust and lubrication treatment of hardware equipment, precision machinery and mould equipment. It features light texture and pure oil properties, matching the transportation requirements of the hose and leaving no impurities to block pipelines. The second category is heat-conducting lubricating media. Some temperature control equipment and precision instruments require oils with both heat conduction and lubrication functions, and such mild oily media can be stably transported through Lubrication Grease Hose. The third category is diluted oil for low-speed equipment lubricating grease and light maintenance oil, applied to daily maintenance and oil supply of bearings and sliding rails on small precision equipment. The smooth inner wall of the hose ensures smooth flow of light oils without residual accumulation.
It is vital to clarify that Lubrication Grease Hose has highly specific media compatibility and clear application prohibitions, which are easy points of confusion for many users. This hose must never convey water, aqueous solutions, rainwater, washing water and other water-based media. Its material cannot resist water infiltration. Long-term water transportation will cause swelling and softening of the hose wall and decline of sealing performance, leading to oil seepage and leakage when lubricating oil is transported afterwards. Meanwhile, acid-base solutions, cutting fluid, rust removers, thinners and other chemical media, as well as various mixed liquids containing impurities and corrosive components, are strictly prohibited from being conveyed by Lubrication Grease Hose. Such media will corrode the hose wall, damage material toughness and cause hardening, cracking and inner wall shedding of the hose. They will not only damage the pipeline but also contaminate the equipment lubrication system.
Matching the conveyed media precisely and avoiding media mixing is the core prerequisite for extending the service life of Lubrication Grease Hose and maintaining stable operation of the equipment lubrication system. Only by strictly using compatible oily media can the advantages of oil resistance, flexibility and sealing of the hose be fully exerted, avoiding pipeline blockage, leakage, accelerated aging and other problems to adapt to long-term operation requirements of industrial equipment.
