Replace wearing parts and more, poor reliability of the piston compressor with high reliability screw air compressor, has become an inevitable trend. According to the statistics: Japan screw compressors in 1976 only 27% in 1985 rose to 85%. Western countries and screw compressor market share of 80%, and to maintain upward momentum. Screw air compressor has a simple structure, small size, no wearing parts, reliable, long life, easy maintenance. Worm, also known as single screw compressor air compressor, meshing pair of single screw compressor by a six screws and two 11 tooth star wheel composition. Worm while meshing with the two-wheel balancing force even if the worm, and also allows the displacement screw compressor manufacturers to double the volume of the air compressor is small, only 9 cubic meters (9m3 / min) per minute worm compressor The weight is only 1/6 of the piston. Worm force balance so that the worm has a number of advantages of screw air compressor oil is good or bad has a decisive influence on the performance of oil-injected screw machine, good oil has good oxidation stability, rapid separation, clear bubble of good, high viscosity, good corrosion resistance, so the screw compressor manufacturers, users must use our special screw pure oil. Oil replaced with new machines for the first 500 hours after the run-in period, after every 2,000 hours of operation replaced with new oil. The best oil change at the same time to replace the oil filter. Places to use in harsh environments to shorten the replacement cycle. REPLACE: Starting compressor run for 5 minutes to allow the oil temperature rose above 50 ℃, the oil viscosity decreases. Stop running, when the oil barrel memory is 0.1Mpa pressure, open the oil barrel oil drain valve at the bottom of a large screw air compressor, connected to storage tanks. Drain valve should be opened slowly, so as not to bring pressure with temperature lubricants scattered wounding dirt. Other oil into droplets after the oil drain valve closed. Unscrew the oil filter, the oil in the pipeline while exhausted, put a new oil filter. Open the oil filler plug screw, into the new oil, so the oil level in the oil standard tick range, tighten the oil filler plug screw, check for leakage. Lubricating oil during use must always check the oil level should be found to be too low to replenish the new oil lines, use of lubricants also must often discharge condensate, generally once a week emission in hot climates should be 2-3 days Emissions once. Down more than four hours, in the case of oil and gas barrel no pressure to play an open valve, exhaust condensate, saw quickly close the valve when the oil flow. Do different brands of lubricants mixed use, avoid extended use of lubricating oil, lubricating oil quality otherwise decline, poor lubrication, lower flash point, can easily result in high-temperature shutdown, causing spontaneous combustion of oil.
