Air compressor free air machine is divided into: 1, the speed of Formula; 2, displacement; displacement divided into rotary and reciprocating; rotary: (1) rotor; (2) Screw; (3) slide Chip. Reciprocating: (1) piston; (2) membrane. Air compressor speed according to the principle can be divided into two categories type and volume. Speed ??of formula: by the action of gas is in the high-speed rotation of the impeller to obtain large kinetic energy, and then a sharp deceleration in the diffuser apparatus, so that the kinetic energy of the gas is converted into potential energy, thereby increasing the gas pressure. Speed ??type mainly centrifugal and axial two basic types. Displacement: by direct compression gas, the gas volume reduced to achieve the purpose of improving the gas pressure, the volume is divided into two categories based on rotary and reciprocating piston cylinder measuring characteristics. Oxygen chamber formulated most positive displacement compressor. Rotary: piston rotates, the piston is also known as a cadre, ranging from the number of rotor cylinder different shapes. Including rotor rotary, screw, vane and the like. In the high-power air compressor control, the conventional instrument control, high failure rate, link parameters between points not close, often malfunction, should not stop when the issue stop signal compressor brand offer, the compressor parking; air compressor brand when it should stop, can not send stop signal Cottle brand air compressor, a tremendous impact to production. Relatively speaking, PLC control and computer control technology development at home and abroad has been quite perfect. Import and export valve at the compressor, to improve its automatic functions, real-time adjustment operation of the system working conditions, to ensure the process parameters under normal circumstances, the maximum possible increase system efficiency. And take advantage of all parameters of the computer integrated process, a more accurate judgments, so that malfunction to a minimum. The use of adjustable systems for anti-surge control. Control system software under normal circumstances can be treated the compressor operating parameters, recording, archiving, the operator can at any time query and analysis. Therefore, the use of running curve forecasting risks, of course, recall the accident function of the system allows the operator to manage Sunburn accurate diagnosis fault. But the air compressor brand authority, abnormal fluctuations in the detection point parameters, may be considered abnormal conditions this car. Sometimes sensor failure and some unexpected parameter fluctuations caused by interference signals. In order to avoid non-air compressor failure outages affecting the operation of other production equipment. Raise awareness of human involvement troubleshooting process, preventive measures. Qin Wei Air (FIG), air compressor brand offer, Hengyang by Xianyang compressor brand Compressor Co., Ltd. Qin Wei. Xianyang Qin Wei Compressor Co. (www.xykyj.cn/) to provide "air compressor and accessories, general machinery parts," such as business, the company has "Wei Qin brand, Coatler card (C?te children)" and other brands. Focus on compression, separation equipment and other industries, have higher visibility in Xianyang. Welcomes inquiries, contact: Liu.
