Cylinders & Solenoid Valves: golden partners in the field of automation, making industrial production more efficient!

In the field of industrial automation, cylinders and solenoid valves are common actuators used in combination. As a driving element in mechanical equipment, the cylinder generates force through compressed air to push objects to move in a straight line; while the solenoid valve is responsible for controlling the switching status and action sequence of the cylinder. This article will provide a detailed analysis of the basic principles, cooperation techniques, and application cases of cylinders and solenoid valves.

First of all, the basic principle of the cylinder is to use the force generated by compressed air to push the piston movement, thereby achieving linear motion of the mechanical components. The cylinder is generally composed of a cylinder, a piston, a piston rod and a seal. When the solenoid valve controls the introduction of gas, the pressure in the cylinder increases, and the piston is pushed forward by the air pressure; when the solenoid valve controls the exhaust, the pressure in the cylinder decreases, and the piston moves backward under the action of external force.

The solenoid valve is the switching component that controls the movement of the cylinder. It consists of an electromagnet and a valve body, and controls the movement of the cylinder by controlling the on and off of the electromagnet. When the electromagnet is energized, the valve core in the valve body will be attracted by the electromagnetic force, making the air path unobstructed and the cylinder working; when the electromagnet is deenergized, the valve core returns to its original position, the air path is closed, and the cylinder stops working.

In order to achieve the cooperation between the cylinder and the solenoid valve, the following technical points need to be paid attention to:

Select the matching solenoid valve and cylinder: Select the appropriate solenoid valve according to the cylinder's working pressure, flow rate, action speed and other parameters. At the same time, the control method of the solenoid valve (one-way control or two-way control) and voltage requirements also need to be considered.

Connection method: The connection methods between the cylinder and the solenoid valve generally include threaded connection, flange connection and plug-in connection. According to the actual situation, choose the appropriate connection method and ensure that the connection is tight and reliable without leakage.

Control circuit design: According to the action requirements of the cylinder, the control circuit of the solenoid valve is reasonably designed. Including selecting the appropriate solenoid valve controller, setting reasonable solenoid valve action time and delay, etc.

Safety protection: During the cooperation process of the cylinder and solenoid valve, safety protection measures should be considered, such as setting up overload protection devices, pressure sensors, etc., to ensure the safe operation of the system.

Maintenance and inspection: Regularly check and maintain the working status of the cylinder and solenoid valve, promptly replace seriously worn parts, and clean and lubricate related parts.

It is worth noting that the matching technology of cylinders and solenoid valves varies in different application scenarios. For example, for cylinders and solenoid valves in special environments, special sealing materials, explosion-proof design or corrosion resistance may be required. Therefore, in practical applications, technical selection and adjustment need to be made according to specific circumstances.

To sum up, the cooperation technology of cylinder and solenoid valve is a common combination technology in the field of industrial automation. By rationally selecting and configuring cylinders and solenoid valves, designing appropriate connection methods and control circuits, and performing safety protection and regular maintenance, the stable operation of the system can be ensured and production efficiency and automation levels can be improved.
