Intelligent sensors are equipped with dedicated computers, whose rapid development has improved the safety performance of air compressors to an unprecedented height. With the development of micro-electronics and micro-mechanical processing technology, sensors are developing in the direction of miniaturization, multi-function and intellectualization. Industry experts are optimistic about the development prospects of air compressor sensors in China. They believe that the increase in the number of air compressors and the use of sensors on each air compressor will determine that the market capacity of sensors in China will increase from time to time, and the sensor market in China is entering a booming period.

Air compressor is a necessary equipment in various factories, roads, mines and construction industries. It is mainly used to provide compressed air with a certain pressure from time to time, such as air supply to pneumatic valves, and air supply to process flow that needs a certain pressure gas. There are many kinds of air compressors, such as screw air compressor, piston air compressor, centrifugal air compressor, scroll air compressor and so on. The market potential of screw air compressor is great, and it has been widely used in many industries. In the control of air compressor, the loading-unloading valve is used to control the air supply of air compressor. Because of the difference of working cycle or consuming technology of Air-using equipment, the air consumption is shaken. Sometimes, the air compressor is frequently loaded and unloaded. After unloading, the air compressor still operates at power frequency, which not only wastes electricity but also increases the mechanical wear of the equipment, and loading is a sudden process, which will have a great impact on the equipment and power grid. Therefore, the transformation of air compressor stop frequency conversion has the effect of improving motor start-up and operation, reducing mechanical wear of equipment and saving electric energy in a certain range.

以单螺杆www.878365.com为例阐明空气紧缩机工作原理,螺杆式空气紧缩机的工作过程分为吸气、密封及保送、紧缩、排气四个过程。当螺杆在壳体内转动时,螺杆与壳体的齿沟互相啮合,空气由进气口吸入,同时也吸入机油,由于齿沟啮合面转动将吸入的油气密封并向排气口保送;在保送过程中齿沟啮合间隙逐步变小,油气遭到紧缩;当齿沟啮合面旋转至壳体排气口时,较高压力的油气混合气体排出机体。
Taking the single screw air compressor as an example, the working principle of the air compressor is expounded. The working process of the screw air compressor is divided into four processes: suction, sealing and delivery, contraction and exhaust. When the screw rotates in the shell, the tooth grooves of the screw and the shell mesh with each other, the air is inhaled by the intake port, and the oil is inhaled at the same time. Because the meshing surface of the tooth groove rotates, the inhaled oil and gas are sealed and delivered to the exhaust port. During the process of the delivery, the meshing clearance of the tooth groove decreases gradually and the oil and gas are compressed. When the meshing surface of the tooth groove rotates to the exhaust port of the shell, Exhaust the body.
采用变频器可经过改动螺杆转子转速的方式来改动排气量,当用气量发作变化时,变频器改动转速的方式调理www.878365.com的排气量,到达排气压力恒定不变,并节约能源的目的。
The air compressor exhaust volume can be adjusted by changing the speed of screw rotor. When the air volume changes, the air compressor exhaust volume can be adjusted by changing the speed of frequency converter to achieve the purpose of constant exhaust pressure and energy saving.
在空气紧缩机控制系统中,采用www.878365.com后端出气管道上装置的压力传感器来控制空气紧缩机的压力。www.878365.com启动时,加载电磁阀处于关闭状态,加载气缸不动作,变频器拖动电机空载运转,一段时间(可有控制器恣意设定,在此设置为10S)后,加载电磁阀翻开,www.878365.com带载运转。当空气紧缩机启动运转后,假如后端设备用气量较大,储气罐和后端管路中紧缩气压力未到达压力上限值,则控制器动作加载阀,翻开进气口,电机负载运转,不时地向后端管路产生紧缩气。假如后端用气设备中止用气,后端管路和储气罐中紧缩气压力慢慢升高,当到达压力上限设定值时,压力传感器发出卸载信号,加载电磁阀中止工作,进气口滤清器关闭,电机空载运转。
In the control system of air compressor, the pressure sensor installed in the outlet pipe of the back end of air compressor is used to control the pressure of air compressor. When the air compressor starts, the loading solenoid valve is in the closed state, the loading cylinder does not move, and the frequency converter drives the motor to run without load. After a period of time (which can be set arbitrarily by the controller and set here to 10S), the loading solenoid valve opens and the air compressor runs with load. When the air compressor starts to operate, if the air consumption of the back-end equipment is large and the compressed pressure in the storage tank and the back-end pipeline does not reach the upper limit of pressure, the controller operates the loading valve, opens the intake port, and the motor operates under the load, and from time to time produces compressed air to the back-end pipeline. If the back-end gas equipment stops using gas, the compressed gas pressure in the back-end pipeline and storage tank increases slowly. When the upper limit of pressure is set, the pressure sensor sends out the unloading signal, loads the solenoid valve to stop working, the intake filter closes, and the motor runs without load.
