Development Trend of Pneumatic Components in China

The expansion of the application of pneumatic technology is a sign of the development of pneumatic industry. The application of pneumatic components mainly includes two aspects: maintenance and matching. In the past, the sales of domestic pneumatic components were used for maintenance. In recent years, the sales share of directly supporting pneumatic components has increased year by year. The application of domestic pneumatic components ranges from metallurgical equipment worth tens of millions of yuan to chairs with only one to two hundred yuan. Domestic pneumatic components specially developed are used in railway switch, locomotive wheel and rail lubrication, train brake, street cleaning, hoisting equipment in special workshop, military command car, etc. This shows that pneumatic technology has "penetrated" into all walks of life, and is expanding day by day. Although China's pneumatic industry has reached a certain scale and technological level, it is far from the international advanced level. The output value of China's pneumatic products only accounts for 1.3% of the world's total output value, only 1/21 of the United States, 1/15 of Japan and 1/8 of Germany. This is not commensurate with a large country with a population of more than 1 billion. From a variety point of view, a Japanese company has 6500 varieties, China has only one fifth of them. There is also a big gap between product performance and quality level.

Diagnosis and Maintenance of Pneumatic Solenoid Valve

1. Pneumatic Controlled Directional Valve The pneumatic control reversing valve uses the gas pressure to make the main spool move and change the gas flow direction. According to different control modes, it can be divided into pressure control, pressure relief control and differential pressure control. Pressure control means that the pressure of the control signal is gradually rising. When the pressure increases to the action pressure of the valve core, the main valve will change direction; pressure relief control means that the pressure of the gas control signal is reduced, and when the pressure is reduced to a certain value, the main valve will change direction; differential pressure control means that the main valve core will change direction under the action of pressure difference at both ends. According to the structure of the main valve, the pneumatic reversing valve can be divided into two main forms: shut-off valve and sliding valve. The structure and working principle of sliding valve type pneumatic directional valve are basically the same as that of hydraulic directional valve. This paper mainly introduces the shut-off directional valve. 2. Pilot electromagnetic directional valve Pilot electromagnetic reversing valve is controlled by electromagnet at first, which generates the pilot pressure, and then the pilot pressure is used to drive the main valve spool to change direction. It is suitable for large diameter occasions. Pilot dual-electronically controlled two-position four-way electromagnetic reversing valve. It consists of pilot valve (Dl, D2) and main valve. The main valve consists of body 1 and piston assembly 2. The figure shows that Dl and D2 are in the state of power failure. The movable iron cores 5 and 6 of the solenoid valve are closed. When Dl is on and D2 is off, the moving iron core 5 is sucked up, and the compressed air from the P port enters the f cavity of the valve through the hole a (dotted line). And from the sealing plug 4 (one-way valve) around the lip into the hole, and into. Wide cavity, push down piston assembly 2, make P and A through, B through the core hole h and T through (exhaust). A port has compressed air output at the same time, some compressed air flows into the hole g, one way through the throttle hole d into the C cavity so that the sealing plug 4 moves down to seal the exhaust hole b, the other way compressed air into the f cavity, which acts on the upper end of the piston assembly 2. At this time, even if the Dl power off, the piston assembly 2 will not be positioned, that is, the valve has memory function. When the pilot valve D2 is energized and Dl is cut off, the moving iron core 6 is absorbed, and the compressed air in the C cavity is discharged through the T1 port. At this time, the compressed air from P to A acts on the large piston and the small piston. Because of the area difference between the big piston and the small piston, the upward force is produced, which makes the piston assembly 2 move up. At the same time, the sealing plug 4 is moved up and the valve opening 3 is opened so that the compressed air at the upper end of the piston assembly 2 is discharged through hole 6. After the piston assembly 2 is moved up, P and B are connected, A and T are connected (exhaust). At this time, even if D2 power off, the upward force due to the difference of piston size and area still exists, so the output state will not change, that is, it has memory function. Pneumatic solenoid valve, like hydraulic solenoid reversing valve, has many types, and its working principle is similar, so it will not be repeated.

Cautions in the Use of Magnetic Switches

Notice that when using two-wire magnetic switch, the load must be connected in series before it can be used, otherwise the magnetic switch will be burned down due to excessive current. Second, when using (DC) DC power supply, Brown should be connected to high potential (+), blue wire to low potential (-), otherwise the indicator will not be on. If the wiring is not the case mentioned above, the magnetic switch will not be damaged. As long as the two wiring are aligned, the indicator lamp can be normally indicated. Third, when using two-wire contactless magnetic switch, it is necessary to use DC power supply, and pay attention to the wiring mode. Brown wire should be connected at high potential (+), blue wire at low potential (-). If the brown and blue wires are misconnected, the magnetic switch may be damaged. Fourth, when using three-wire contactless magnetic switch, it is necessary to use (DC) DC power supply, and please pay attention to NPN or PNP wiring mode. Brown wires are connected at high potential (+), blue wires are connected at low potential (-), and black wires are connected to the load in series. If the three lines of brown, blue and black are misconnected, the magnetic switch may be damaged. When using load as inductive load (such as relay and solenoid valve), please connect the protective elements at the load side in parallel, so as to prolong the life of magnetic switch. If connected to (DC) DC inductance load, please connect a bipolar body to the load and pay attention to the polar direction of the bipolar body. Misconnection may cause damage to the magnetic switch. If connected to (AC) AC inductive load, please connect an R-C circuit to the load. 6. When using magnetic switches, they should be as far away from the strong magnetic field or the surroundings with magnetic conducting metals as possible to avoid interference. When the load is a capacitive load or the length of the wire is more than 10 meters, please connect an inductor (560-1000 mH) in series. The inductor is as close as possible to the magnetic switch, so as to ensure the normal operation of the magnetic switch.
