Efficiency is closely related to domestic and foreign users concerned compressor machine gap energy conservation and efficiency differences between screw machine, because the nose is leaking inside cause the compressor efficiency decline. Leakage within a screw head at a specific pressure and lubrication condition is basically constant, that is just about the amount of internal leakage Cottle air compressor, and speed has nothing to do with the intake and exhaust pressure difference and the fuel injection quantity. That is a screw speed is higher, namely displacement, the smaller the relative amount of leakage, the higher the efficiency. But the speed increase will bring lower reliability, carbon tends to increase, increased seal and bearing wear, shortening the life of the machine and other issues. Where the thrust bearing wear caused by changes in the exhaust side of the gap, resulting in rapid deterioration of the efficiency of the machine. Assess whether a compressor before saving, first make sure it's the speed, if it is at 3000 rev / min 2 or above in order to achieve an energy efficiency, this machine is certainly at the expense of reliability, the cost in exchange for energy conservation target . Many foreign clients in the procurement compressor mature, not only concerned about the costs incurred once the purchase and installation, operation and maintenance costs concerns, but also carefully assess the cost of quality. The so-called cost of quality refers to the production loss may be caused by failure of the compressor. Thus, the quality of the cost of attention to domestic users are very different, domestic users rarely seriously consider the cost of quality. Cottle troubleshooting a compressor, compressor production Cottle checked before: two, Cottle lower air compressor displacement causes of failure and repair methods: Failure: Cottle air compressor displacement reduced by 1, failure reasons: lack of oil displacement is reduced and there is a direct relationship between the lack of oil. We once in production, compressor appeared to reduce the fault displacement compressor rental, not only can not make the press roller down, and accompanied by some Knocking sound. 2. Cause: The air filter and muffler bad valve tightness Maintenance: reducing the displacement is also related to the air tightness of the filter and valve silencer. Muffler air cleaner must wash cleansing. On dirt valve plate, valve on the compressor cleaning is beneficial to ensure the normal displacement. Under routine every 200 hours on the filter should be cleaned once every 500 to 800 hours should be cleaned once a valve. 3, the failure reasons: poor quality lubricants Maintenance: poor quality lubricants can cause piston rings to be sucked, thereby reducing the displacement. Therefore, you should choose high-quality lubricants. After long-term work, will contain impurities, such as dust in the oil, and therefore must be filtered. In general, every 500 to 800 hours should be replaced once the oil, and the oil before the first use of filtering. 4, because air compressor malfunction: exhaust temperature ultrahigh repair method: the exhaust temperature will cause the piston rings are ultra suck, cause displacement decreases. As long as the temperature is lowered, they can solve the problem. Here we must note two things: (1) high ambient temperature should generally not exceed 40 ℃. (2) If the valve leakage Qin Wei air compressor, high-temperature exhaust gas will return cylinder which we should be careful to check the valve, the valve plate to replace the valve grinding European films, it was possible to solve the problem of ultrahigh temperature.
