PVC High Speed Door are designed for indoor use and ensure rapid handling operations between different areas that should remain separated. These safe and efficient industrial doors are made of a shaped steel frame and covered with PVC. These high speed doors are safe and efficient and consist of a shaped steel frame covered with PVC. Safety is ensured by their photocells and barriers.
High speed doors protect us from harm, save energy and help us to separate processes for optimal productivity. A high speed door's most important job is to simply open and close quickly and safely every time you need it.
The high speed pvc roll shutter door require high strains, caused by the high operating speed and the frequency of openings, have to be taken into account during construction. In the same way, basic conditions like size and installation location add up to considerable requirements regarding safety and control technique.
Jinzexin Pneumatic Valve Co., Ltd. is a professional manufacturer integrating development, research, production and sales of steel pipe fittings. It specializes in selling Shanghai valves, Shanghai pneumatic heads and Shanghai pneumatic valves.
The actuators are divided into electric and pneumatic.
Taking pneumatics as an example, pneumatics are separated into single acting (spring reset) and double acting. The screw is driven by the compressed air to drive the valve stem to rotate.
1. Select the actuator according to the size of the gas source (instrument gas)
2 , the output torque of the pneumatic actuator depends on the torque required by the valve
The torque required for the valve to open and close determines the output torque of the electric actuator. It is usually recommended by the user or the valve manufacturer can choose it. As the actuator manufacturer, it is only responsible for the output torque of the actuator. The torque is determined by factors such as valve size and working pressure. However, due to the difference in machining accuracy and assembly process of valve manufacturers, the torque required for different specifications of valves produced by different manufacturers is also different, even if it is produced by the same valve manufacturer. The torque of the specification valve is also different. When the torque selection of the actuator is too small, the valve cannot be opened and closed normally. Therefore, the pneumatic actuator must choose a reasonable torque range. (Shanghai Jinzexin Pneumatic Valve Co., Ltd.)
2. The torque required to turn the valve is too small to turn, and too long the valve life is not long. Usually 30% to the torque margin left on OK.
The difference is that when the torque selection of the actuator is too small, the valve cannot be normally opened and closed, so the pneumatic actuator must choose a reasonable torque range.
