Coatler compressor overtemperature Failure Analysis Coatler screw compressors are designed with ultra-high temperature protection Cottle compressor, once the exhaust temperature exceeds 100 ℃, the temperature sensor temperature switching command, alarm and automatically shutdown Qin Wei air compressor, readable on the dashboard with the exhaust temperature was higher 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 compressor prices, overtemperature faults, more 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 course of the operation of the compressor equipment, 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, the cooling system compressor temperature determine the cause of the fault occurrence time oil filter blockage within 20 minutes of high temperature, cooler blocked within 10 minutes of high temperature, temperature control valve blockage, within five minutes of high temperature, air filter clogging, within one hour of high temperature, mechanical head of sudden death, instant heat. Intake design approach is positive, that is to be fully sealed enclosure door to the heat of the radiator, open the case if the chassis cover to change the air flow, resulting in lack of air flow through the radiator, and produce heat. First make sure that the machine is faulty temperature measurement devices, you can use another proofread thermometer, temperature measurement devices no problem if it is confirmed, then check the oil cooler temperature difference between imports and exports, normally between 5-8 ℃. If the temperature is greater than this range, indicating that the oil filter clogging, or thermostatic valve not fully open. If the above methods fail to resolve, we must consider whether the oil blockage. If the temperature is less than the normal range, proved to be poor heat dissipation, check for dirty radiator, cooling fan if abnormal, insufficient air flow. The wind in the wrong direction. If the temperature in the normal range, the machine is still hot. Description calorific nose outside the normal range, you should check whether the overpressure operation, whether oil aging, whether the nose bearing problems. Cottle Compressor |??
