Compressor is mainly composed of the body, the crankshaft connecting rod, cylinder piston, intake and exhaust valves and other components. When the motor is driven by the crankshaft running. By a piston rod driven to reciprocate in the cylinder, and the suction, compression of the refrigerant is completed, exhaust, expansion, and exhaust valve during inspiration under complex: (1) the compression process: after the low pressure gas refrigerant then compressed to a high pressure gaseous process, known as the compression process. When the piston moves to the lower end (i.e., the position of the piston can no longer down), the inner cylinder is filled with low-pressure gas refrigerant compressor outlet Cottle, the piston begins to move upward along the cylinder, the suction valve is closed at this time the air compressor manufacturers offer cylinder internal volume decreases. And in a closed cylinder. Gas refrigerant is compressed, the pressure and temperature will be gradually increased. When the pressure reaches the discharge pressure, the exhaust valve opens automatically begins exhaust. (2) process exhaust: gas refrigerant at the end of the compression process, starting from the discharge valve, the piston continues to move upward, the gas pressure inside the cylinder is no longer increased, and continue to exhaust. Exhaust piston reaches the end of the process until the end [ie the piston can not move upward position). (3) Expansion process: start to move as soon as the piston reaches the upper end downwardly along the cylinder, the exhaust valve is automatically shut down, then the clearance volume remaining in a small amount of high-pressure gas refrigerant, a pressure drop volume increases called expansion process. (4) Since the piston at which point it starts to move downward to a certain position, the gas refrigerant remaining in the cylinder pressure reaches the suction pressure, the end of the expansion process, the piston continues to move down. When the in-cylinder gas pressure is lower than the suction pressure, the intake valve will automatically open, and the low-pressure gas refrigerant into the cylinder. When the piston moves to the next lower end, and full of gas in the cylinder, this time to complete the process of breathing and is ready to complete the next compression process. So as to study the motion cycle low-pressure gas into high-pressure gas in the compressor, and the refrigerant delivered from the evaporator to the condenser. For reciprocating piston compressor body inertia force that can not be eliminated, so the runtime vibration, high noise, the need for specialized fixed base when the larger piston compressor 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, high speed screw compressor, gas compressor manufacturers ranking smooth, non-pulsating flow 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 to manage air compressor equipment manufacturers, 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 with high efficiency Instead, the developed countries have become a reality. Based on the above mentioned, in order to reduce production costs and increase economic efficiency, easy device management. Well-known manufacturer of air compressor |??
