The differences and connections between Pneumatic solenoid valves and Pneumatic cylinders
Answer: The Pneumatic solenoid valve is for control, and the Pneumatic cylinder is for execution!
1. A Pneumatic cylinder is a pneumatic mechanical component used to achieve mechanical movement or action and is driven by compressed air.
2. The Pneumatic solenoid valve is an electric valve that controls the air path of the controller Pneumatic cylinder. It is used to switch and control the opening and closing of the air path, and to control the action of compressed air on the Pneumatic cylinder, causing the Pneumatic cylinder to move and act.
3. With the Pneumatic cylinder and Pneumatic solenoid valve in place, a controller for the Pneumatic cylinder is also required. Usually, the TPC8-8TD timing program controller is adopted as the controller for the Pneumatic cylinder. The required functions can be set through a table without programming, which can conveniently achieve the automatic control of the Pneumatic cylinder equipment.
How to match and select Pneumatic solenoid valves and Pneumatic cylinders
Single-acting cylinder - 3-way Pneumatic solenoid valve
Double-acting cylinder - 4.5-way Pneumatic solenoid valve
Control of various fluids - 2.3-way Pneumatic solenoid valve
The on-off actions of the double-acting cylinder are all driven and executed by the air source. Open the ventilation, close the ventilation, and maintain the original position when the gas is cut off.
In a single-acting switch, only the on action is driven by the air source, while the off action is returned by the spring. (There are more micro-Pneumatic cylinders
Single-acting types: normally open type and normally closed type.
Normally open type: (Closed when gas is supplied and open when gas is cut off)
Normally closed type: (Open for ventilation, closed for ventilation).
The stroke is the same and is selected according to the specific requirements of the work and mining. Single-acting is generally used in the case of power or gas cut-off, when the valve needs to be opened or closed. Single-acting is more expensive than double-acting. Generally, double-acting is commonly used. Specifically, it still depends on the user's mining and industrial conditions.
The comparison of the advantages and disadvantages of single-acting Pneumatic cylinders versus double-acting Pneumatic cylinders is as follows: Advantages
1. Single-acting is cheaper than double-acting and requires less cost for the entire gas path.
2. The return speed of the cylinder spring is stable and is not affected by changes in air pressure.
Disadvantage
1 . Under the same pressure and flow rate, the speed of single-acting is slower than that of double-acting.
2. Single-acting has a single function compared to double-acting. For example, a double-acting device can be connected to a three-position five-way middle seal, medium pressure, etc., to achieve safety functions, but a single-acting device cannot achieve this function
There is a spring inside the single-acting cylinder for resetting. If the stroke is too long, the spring also needs to be very long, resulting in a long total length of the cylinder. The spring is unreliable, and the thrust during the process changes too much and is unstable. So single-acting Pneumatic cylinders are generally short-stroke, small Pneumatic cylinders.
