Explosion-proof solenoid coils are special solenoid coils that are mainly used in environments where there is a risk of explosion. Its basic principle is based on the phenomenon of electromagnetic induction. When electric current passes through the coil, a magnetic field is generated around the coil. This magnetic field can interact with the iron core…

I. Working principle A 5/2 solenoid valve is a key component in industrial automation control. Its core principle lies in using electromagnetic force to control the movement of the spool, thereby accurately regulating the flow path of fluids (gases or liquids). With its compact structure and powerful functions, it is widely used in pneumatic control systems….

Air storage tanks use the sealing and pressure resistance of the tank body to store compressed air or other gases, playing the role of buffering, storing and stabilizing pressure. In compressed air systems, a gas storage tank is usually installed between the air compressor and the gas-consuming equipment, and the gas is released through the…

The winding method of thermoplastic solenoid coils is a key process step that directly affects the performance and reliability of the coils. The following are some detailed descriptions of the ways thermoplastic solenoid coils are wound: I. Preparation before winding Selection of appropriate insulating materials: Thermoplastic insulating materials typically include polyimide, polyketone, PTFE, etc. Different materials have different…

The micro solenoid valve cannot be used after being powered on, which may be caused by the following reasons: I. Power supply related issues 1. Insufficient or excessive voltage  • Solenoid valves have a rated operating voltage range. If the actual supply voltage is lower than the rated voltage, solenoid valve may not be able to generate…

As an important part of explosion-proof electrical equipment, explosion-proof solenoid coils play a vital role in hazardous environments such as petroleum, chemical, and mining. However, many users have found that the life of explosion-proof solenoid coils is often short, which not only increases the cost of equipment maintenance, but also may cause safety hazards. So,…

ressure relief valve, also known as safety valve, is a crucial safety protection device. The main function is to automatically open and release excess pressure when the pressure inside the system exceeds the predetermined safety value, in order to prevent equipment or pipelines from being damaged due to overpressure and ensure the safe and stable…

A vacuum generator is a device that uses a positive pressure air source to generate negative pressure, and the following are the main factors that affect its performance: I. Compressed air supply pressure  • Principle: The pressure of compressed air is directly related to the ability of the vacuum generator to generate vacuum. According to Bernoulli’s…

In modern industrial and automation technology, directional control valves play a crucial role as a key fluid control component. Directional control valves are not only able to change the direction of flow of fluids (such as hydraulic oil or compressed air) in the system piping, but also accurately regulate the action of actuating components (such…

The cylinder is a pneumatic actuator that converts the pressure energy of compressed air into mechanical energy to achieve linear reciprocating movement or swing. In the industrial field, cylinders are widely used in many industries such as automated production lines, mechanical equipment, automobile manufacturing, food packaging, etc. due to their advantages of simple structure, reliable operation,…
