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…

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,…

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…

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…

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…

I. Working principle 5/2 solenoid valve, as a key component in industrial automation control, the core of which lies in the movement of the spool through the electromagnetic force control valve, so as to accurately regulate the flow path of the fluid (gas or liquid). With its compact structure and powerful function, it is widely used…

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…

Thermoplastic solenoid coil is a solenoid coil made of thermoplastic material. his type of coil is mainly made of thermoplastic materials such as polyamide, polyester, and polypropylene, which have good plasticity at high temperatures and can easily change shape and size. Thermoplastic solenoid coils work on the principle of solenoid induction. When powered on, the…

A high-frequency solenoid valve is a solenoid valve that can quickly switch its working state, and its response time is a key indicator to measure its performance. I. High frequency solenoid valve response time range Extremely fast type: under ideal experimental conditions, the response time of some high-end high-frequency solenoid valves can reach 1 – 3…

I. Causes of valve leakage 1. Causes of internal leakage  • Sealing surface damage: When the valve is used for a long time, the impurity particles in the medium will cause erosion and wear on the sealing surface. For example, in a slurry pipeline containing solid particles, such as the pulp conveying pipeline in the paper industry, solid…

What is the compensation function of digital pressure switch? The compensation function of the digital pressure switch refers to the function of correcting and adjusting the output signal of the pressure sensor through the built-in intelligent algorithm or circuit in order to improve the accuracy and stability of pressure measurement. This compensation can eliminate or…
