1, the air output temperature is too high (1) to reduce the input screw air compressor air temperature. Increase air compressor room ventilation in the room plus roof exhaust hood, used to exclude heat, control room temperature is not too high. In summer, the air compressor room temperature should not exceed 40 ℃. (2) reduce the cooling water inlet temperature, winter water temperature maintained at 18 ℃, summer water temperature maintained at 24 ℃. (3) increase the flow of cooling water, the estimated brand compressor cooling water inlet temperature and the output temperature difference l5 ℃, the cooling water flow rate of 3.7 liters / sec. (4) removal of the cooling water scale or dirty sediment. In the cooling water by adding detergent to clear cooling water system. 2, high oil temperature screw compressor screw compressor oil temperature protection settings, oil temperature exceeds 70 ℃, shut down, resulting in frequent compressor shutdown. Oil temperature is too high because the oil cooler failure. Since the cooling water circuit in the oil cooler is fine, easy to clean up after fouling, resulting in the oil temperature does not drop down. Replacing an oil cooler and too expensive. After the study explored using the following methods to clean the cooler is better. Remove the oil cooler, soaked in detergent in one day, and then a small pump water under pressure into the oil cooler repeated washing, the scale can be removed in summer to control the oil temperature below 60 ℃. 3, the air filter frequently fail to start using screw air compressor, the air filter is only one month on the failure. The analysis of ambient air is dirtier. For this reason above plus access cover on the air compressor air filter, longer filter life. 4, screw air compressor screw air compressor motor burned frequently during use, the main motor frequently burned over a period of time. The main reason is that no one thing has its maximum operating pressure, and over the working pressure and long-running, long-term overload, it will cause the compressor motor overheating, burning motor. For reciprocating piston compressor body inertia force that can not be eliminated, and therefore good vibration compressor runtime Which brand? High noise, the larger piston compressor requires specialized fixed base installation. Rotary screw compressor for sports organizations, well-balanced, vibration, low noise, no installed base. Reciprocating piston compressor is intermittent supply, gas pulsation when running large compressor brand outlets, screw compressors, high speed, stable gas, no gas pulsation, to meet the requirements of high volume users. Piston compressor basically no automatic control system. Screw compressors are perfect automatic control and protection systems, mechatronics products are convenient for equipment maintenance and management, but also to maximize the reduction of energy consumption. Screw compressors can tolerate high speed, so the structure is much smaller volume than the same displacement piston compressor, the same power is also much larger displacement compressor. Plus the internal temperature of the exhaust gas cooler than the lower piston compressor is about 50 to 60 degrees. If the model species used too much, too scattered, it is neither easy device management, but also increased the number of wearing parts, and is bound to increase the cost of normal operation. Meanwhile decentralized arrangement exacerbated by pollution of the production environment. Piston compressor piston ring wear existence, running despite the oil scraper ring on the piston, but still there are a lot of oil went to the cylinder, the one with the gas discharge. So while reducing the gas quality, it also increases fuel consumption. Screw compressors have efficient gas separation systems and filtration equipment, supply high-quality, fuel consumption is low. Based on the above relevant circumstances, many domestic enterprises in the use of the low-pressure compressor, the phasing out of high operating costs, low reliability of the piston compressor, screw compressor replaced with efficient air compressor brand wholesale, In developed countries has become a reality. Based on the above mentioned, in order to reduce production costs and increase economic efficiency, easy device management.
