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 the heat has not been transferred, before the next injection operation, after the oil cooler needs to be 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. You can check the oil barrel when the oil level Cottle compressors, pressure relief after the shutdown, the lubricant 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 due to lack of oil hosts 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, compressor oil cooling system must have the capability a suitable viscosity suitable viscosity enables compressor play a good lubrication, cooling and sealing effect at the operating temperature and pressure, to ensure the normal operation of the compressor. 2, good oxidation stability because the exhaust temperature of the compressor are usually at 120 ℃ ~ 200 ℃, there is likely to reach 300 ℃ air compressor repair, compressor oil susceptible to oxidation at high temperatures and deterioration of sludge generated. 3, coke coke gathered tendentious exhaust system will make the exhaust valve closed lax air compressor, while the cooling effect is poor, so that the exhaust temperature, compressor failure, or even fire, explosion, Therefore, the demands of the compressor coke bias. 4, good anti-emulsification, anti-corrosion and anti-foam compressor oil, condensate and easily mixed with air, the oil emulsion deterioration, increased mechanical corrosion, wear, oil oxidation, so requires a good resistance to emulsification , corrosion and oxidation resistance.
