Tge motor oil testing, lubricating oil cleanup, oil dumping point testing
China is testing the quality evaluation and failure diagnosis of more than 100 oil items, including lubricant, lubricant, grease, special oil, diesel, transformer oil, in accordance with national standards (gb), iso, astm, and product quality standards. Test reports are mutually recognized by more than 70 countries, and oil quality assessments are credible and can serve as a basis for legal arbitration。
Water in engine oil and mechanical impurities:
(a) when the engine is operating normally, the oil should look transparent, but if the oil system leaks water, gas and the oil is seen from outside in a state of disrepair and emulsion, it will damage the oil sheet, affect the lubricants of the oil and cause wear and tear to the crew; the water leaking into the aircraft at the same time, such as prolonged contact with metal components, will cause varying degrees of corrosion on the metal surface, which can cause carvings in the speed-reducing system, even causing downtime accidents and aging oil. When water is found to be in or out of transparency in the oils of the operating motors, the reasons are identified at an early stage, measures are taken, such as the use of tanker oil filters, the regular discharge of water from the bottom of the tanks, etc., and requirements are made to adjust the axle envelopes, axle seals, and to ensure the oil content of the aircraft。
Mechanical impurities are particulate matter, such as welding, oxidation, metal sales, sand, dust, etc., in which the oil contains mechanical impurities, especially hard solid particles, which can cause the wear and tear of the speed-reducing system, wear and tear of the section (axis, axes) in which the crew turns and, in serious cases, cause accidents, such as motor vehicles, which seriously threaten the operation of the crew, so that the impurities allowed for the engine oil used in the plume equipment at speeds greater than 8,000 r/min are below w0. 1。
Trans flat oil/air engine oil testing facility
Gas tanker oils, also known as grader oils, typically include steam engine oils, gas turbine oils, hydro turbine oils and anti-oxygen engine oils, which are used mainly for the lubrication of taxi bearings, gear-reducing gears, gear switches and hydraulic control systems for motor oils and associated motor groups. The role of tanker oils is mainly one of lubrication, cooling and velocity。
