Many people know that in fact screw air compressor is a positive displacement gas compressor, which is bound by a mutual tooth rotor, chassis and properly configured in intake and exhaust ports at both ends of the working chamber consisting of a compressed gas, by reducing the working volume to increase the gas pressure. As the market changes in the present oil-free compressor manufacturer, air compressor so that more and more people's attention then to some of the problems we Bolet air compressor at work and routine maintenance, it is noted to be a simple presentation, we are hoping to be helpful to everyone; each over a period of time, the filter must be cleaned of crude oil filter and fuel tank level filter on the filter with a wire brush to remove dirt from the air compressor factory online cleaning , because the compressor work in dusty environments, air filters and oil filter regular cleaning is essential, it is best to ignore this problem is necessary, because sometimes a small problem big problem will evolve. Cleaning the filter cartridge, dry cleaned, then soaked in the same oil tank, if dust is very serious, the cleaning cycle is determined according to the actual situation. As can be seen when the unloader valve on air pollution indicator of the red line, then the air filter polluted air compressor manufacturers Cottle, clean the air filter. Cleaning or inspection offload valve, minimum pressure valve and automatic venting valves and other components. Thoroughly cleaning the oil filter air compressor manufacturers offer, will be deposited in the dirt at the bottom of the oil filter clean. You must replace the oil filter paper filter. Check valve, temperature control valve, pressure regulator, pressure regulator valve is working properly; check the oil pump, inspect or replace the seals. Oil emulsified foundation level, changes in the number, the viscosity of the impurities, as appropriate, replaced with new oil. During this time without performing special maintenance. We found a significant increase in the compressor oil should be consumed for inspection or replacement of the core, of course, is also the host overhaul, if necessary, technical radial bearings and thrust bearing replacement work. 1, the air filter clogged air filter needs to be replaced; 2, the vent valve can not be closed, need maintenance vent valve; 3, the air demand is greater than the nominal displacement compressor; 4, the intake valve closed in advance, check and unloading valve solenoid valve, pressure regulator is working properly, replace the maintenance package as necessary; check the computer board / pressure switch setting is appropriate. An intermediate pressure compressor cold and dry process can not start Failure Analysis: Step 1: Check the information on the display panel of the dryer, the indicator whether the abnormal phenomenon. When the high pressure anomaly lights could be: less cooling water, high temperature, condenser does not work damaged or blocked, air flow over the source. When the low-voltage lights might be an exception: the refrigerant filter is not working properly, damaged or blocked. Step Two: Check remote start relay normally open contact. Step 3: Check the dryer voltage. Step four: start point on the use of the dryer panel boot device. _ Air compressor manufacturers offer Qin Wei Air (certified) _ Weinan, Xianyang compressor manufacturers to provide the Compressor Co., Ltd.
