Solenoid Automation
Jun 26, 2017

Solenoid According to the different power supply using solenoid valve can be divided into AC and DC solenoid valve, solenoid valve, is an electromagnetic control of industrial equipment, mainly for automatic flow control of the key components, are actuators, speed and other parameters, Solenoid widely used in industrial Control system to adjust the direction of business. Solenoid valves can use different circuits to achieve the desired control objectives, so that control accuracy and flexibility can be guaranteed. Solenoid valve in the work coil need to maintain long-term power consumption, energy consumption. Solenoid valve is widely used, although it is easy to control, Solenoid but the power consumption is considerable.

The traditional DC solenoid valve body and the coil is generally composed of two parts, including the valve seat, valve sleeve, moving core and static core and reset the spring, Solenoid including the magnetic frame, pin and guide frame magnetic coil skeleton, Coil, coil connecting wire. The coil is mounted on the valve body and fixed with screws.

    The working principle is: when the coil power, Solenoid the coil produces magnetic field, the role of dynamic electromagnetic force, in the core to overcome the spring force and static iron core pull, the valve port open, the valve import and export channels. When the coil is broken, because the coil no current flow, no magnetic field, the action reset spring core, and the core of the static core separation, the valve port closed, the valve inlet and outlet closed.

    As the traditional solenoid valve power supply voltage is not adjustable, so the attraction is still the original high power, so not only power loss, Solenoid will lead to coil temperature rise, the coil manufacturing made a higher demand, not only high energy consumption, Solenoid High cost, price difference. In the traditional single coil structure used in the DC solenoid valve coil, by the same coil to complete the pull and maintenance, not only energy consumption, and the coil temperature rise is too high, affecting the coil life. After testing, the solenoid valve remains running, the power consumption of the coil is only 20% of the rated power.

Electromagnetic valve (Electromagnetic valve) is an electromagnetic control of industrial equipment, is used to control the fluid of the basic components, Solenoid are actuators, not limited to hydraulic, pneumatic. Adjust the direction, flow, speed, and other parameters of the media in an industrial control system. Solenoid valves can be used with different circuits to achieve the desired control, Solenoid and control accuracy and flexibility can be guaranteed. There are many kinds of solenoid valves, different solenoid valves in different parts of the control system to play a role, the most commonly used is the one-way valve, safety valve, Solenoid directional control valve, speed control valve.

The solenoid valve has a closed cavity, in different locations open through the hole, each hole connected to the different tubing, the middle of the cavity is the piston, both sides of the two electromagnets, which side of the magnet coil valve body will be attracted to where Side, Solenoid by controlling the movement of the valve body to open or close the different drainage holes, and the oil inlet is normally open, Solenoid the hydraulic oil will enter a different drain pipe, and then through the oil pressure to promote the piston cylinder Driving the piston rod, the piston rod drive mechanism. This control of the electromagnet by the current on and off to control the mechanical movement.
