Air compressors have anything to do with cleanliness? Because of the role of wind in the air, always contain different levels of dust and other impurities in the air if too gray sand impurities, the compressor has considerable harm. Endanger the following points: 1, sand quite hard wear of the cylinder, piston rings, piston fillers and other parts, shorten the life of the machine; 2, and dust from entering the cylinder lubricating oil mixed in the cylinder, piston ring Coke block form, on the one hand Qin Wei hinder machinery lubrication compressor, causing pull-cylinder, Calatrava; on the other hand in the compressor high temperature, sand and more cases could cause an explosion; 3, sand-lime easy to plug into the compressor valves, coolers, air lines and pneumatic machinery, causing compression device is not tight, so reducing the amount of wind; 4, due to the dust will increase the wear of the compressor, compressor lubrication undermine the impact of gas cooling air compressor parts, resulting in a compressed gas The final temperature increased, the power consumption will also increase dramatically. Therefore, before the air or other gas enters the compressor must be equipped with controllable filter device, to prevent dust and impurities into the cylinder, to prevent relative sliding movement of the wear member has a sharp increase, oxidation of the lubricating oil can be prevented. Coatler compressor overtemperature Failure Analysis Coatler screw compressors are designed with ultra-high temperature protection, once the exhaust temperature exceeds 100 ℃, the temperature sensor temperature switching command, alarm and automatically shut down, with the dashboard Readable obtained exhaust temperature is greater than 100 ℃. Measures to cool down the machine itself is the lubricant from the lower left and right ends of the body and injected into the compression chamber, and the intake air compressed to participate, discharged from the bottom of the main oil barrel. It is in addition to the screws and bearings, gears and other parts for lubrication, but at the same time will be a lot of tropical out. But when the heat has not yet been transferred, before the next injection compressor operation, after the oil cooler needed to completely cool. Therefore, over-temperature fault occurs more with abnormal lubrication and cooling system related. To analyze the following: a lack of lubrication system components and the oil amount of lubricating oil or the oil components work will cause abnormal temperature rise, causing over-temperature fault. ① earn starvation system. When the oil barrel oil level can be checked after the shutdown relief, lubricants in static, oil level should be high and the oil flag H (or MAX) is slightly higher. In the device during operation, the oil level can not be lower than the low oil level mark L (or MIX). When found insufficient oil or the oil level is not observed, should be immediately stopped to refuel. ② oil shortage. First check the oil filter, oil separator fine clogging. ③ oil stop valve is not working properly. Oil stop valve generally two two-way normally closed solenoid valve, when starting to open, closed down, to avoid shutdown barrel of oil and gas continue to spray into the nose, and discharged from the intake port. If the component failure Cottle, the host due to lack of oil rapid warming will cause serious burn screw assembly. ④ thermal control valve operation failure. Thermal control valve is mounted on the front of the oil cooler, its role is to maintain the pressure head exhaust temperature above the dew point. ⑤ lubricant specification incorrect or poor quality. Screw machine lubricants generally have strict requirements and can not substitute, should be in the manual of the equipment requirements for the Huai. 2, the cooling system air compressor parts, air compressor, air compressor Qin Wei, Wang Cottle compressor cost provided from Xianyang Qin Wei Compressor Limited.
