The data indicates that more than half of the main causes of mechanical failure or early wear are related to lubrication technology management. Improve lubrication management, prevent scratching or sintering of friction moving parts such as NSK bearings and gears, prevent and reduce wear, reduce frictional resistance, prevent equipment accidents, improve equipment production efficiency, save energy, improve energy efficiency, and increase Economic efficiency is the main task of lubrication management.
1. Lubrication management is a professional technical management. Full-time lubrication technical management personnel should be set up to develop a lubrication management system and train lubrication technical knowledge.
2. Under the premise of reasonable fuel tank capacity, keep the oil tank reasonable oil level, often add lubricating oil to the fuel tank, so that the oil in the fuel tank is always in a reasonable operating oil level, degas the oil, precipitate the machine, separate the water and It is advantageous to reduce the oil temperature in the tank.
3. Timing, positioning and extraction of oil samples in operation, testing and testing from oil odor, color, viscosity change, water content, water separation performance, pollutant type and content, anti-foaming performance. When the water content in the oil entering the lubrication point exceeds 0.1%, the mechanical wear increases sharply; the lubrication condition exceeding 0.5% is very dangerous. Make a test record.
4. Analyze and compare each test record, predict and forecast the poor lubrication state, and formulate improvement or preventive measures. It is safe and reliable to control the oil level, oil quality, oil temperature and oil pressure of the system to prevent the occurrence of lubrication accidents.
5. Prevent contamination of oil and control oil:
(1) Oil product purchase, storage, storage, issuance and waste oil treatment, there should be a strict management system, according to different varieties and grades, there are obvious easily distinguishable signs or signs, indicating the name, grade, date, etc. . It is forbidden to mix and store to prevent misuse and cause oil mixed accidents.
(2) During storage, storage and storage, the container should be strictly cleaned and sealed to prevent the intrusion of dust, impurities and rain. It should be stored in a darkroom that is protected from light, cool and ventilated, and has a fire exit. When temporarily storing in the open air, the bucket cover should be kept in a slightly inclined position to prevent rainwater from entering. Oil should not come into contact with metals such as copper and lead that promote oxidation.
(3) Main items of re-inspection of lubricating oil acceptance: viscosity, viscosity index, water content, demulsibility, extreme pressure. Cleanliness requires mechanical impurities within 0.01%, no moisture and deposit marks.
(4) The manhole cover on the top of the fuel tank should be tightly closed and should not be opened. The air filter has an filtration accuracy of 100 mesh or more, and is regularly inspected and cleaned, and the drain valve at the lower part of the fuel tank is periodically discharged. Add lubricant to the tank to apply the pipeline pumping and install a filter with appropriate filtration accuracy. The tank should be cleaned of the sludge regularly, and the inner surface of the tank should not be rubbed with a fabric.
(5) When replacing the blocked filter element, the oil in the filter cartridge should be drained, so that the dirt can enter the downstream pipeline of the filter, causing serious irreparable secondary pollution, otherwise the normal lubrication at the lubrication point will be directly endangered.
(6) According to the changes in the chromaticity, viscosity, moisture and pollution degree of the oil used, the oil is changed according to the quality.
6. For the first time, the unit that uses oil film
bearing oil, in addition to the complete thorough circulation cleaning of the original lubrication system and equipment, must also do the following work:
(1) Compare and analyze the standard value and actual test value of the physical and chemical performance index of the oil film bearing oil with the physical and chemical indicators of the oil products of the relevant domestic and foreign manufacturers, and formulate the work plan and accident situation for the alternative use according to the conditions of the equipment. The technical measures at the time of the occurrence are foolproof.
(2) The oil department shall organize relevant technical personnel to conduct oil product technical data analysis and discussion in order to fully understand the performance of the oil product and the correct use method.
(3) A blending test between new oil and used oil, between the twoLubrication management of oil film NSK bearing oil
