The train door must be able to work stably, quietly, reliably and safely. Generally, the train door needs to be able to operate under some extreme conditions, such as high temperature, high humidity or low temperature. In addition, the train will vibrate continuously during operation, so the train door must also be able to withstand frequent impact. Even if the track is well maintained, the train will still produce vibration when running. Train doors are often very heavy. In order to reliably open or close them in complex environments, rodless pneumatic cylinders must be used. The following describes the advantages of rodless air cylinder when applied to train door.
Cost-Efficient
On the train door, the rodless compressed air cylinder usually works with the pneumatic system. Since the pneumatic system has been installed on the train, and the pneumatic system is also used for other purposes on the train, such as braking, etc. If an electronic system is used to control the train door, it will be necessary to install an electronic system on the train, resulting in increased cost.
On long-distance trains, train doors do not need to be opened or closed frequently. In addition, the opening or closing speed of train doors does not need to be as fast as that of short distance trains. In this case of low requirements, the rodless double ended cylinder can run reliably, and its cost is lower than that of electric motor.
Reliable
The train door controlled by rodless double acting cylinder is not only reliable, but also easy to operate. The rodless rotary pneumatic cylinder can usually provide a cumulative linear stroke of tens of millions of feet, so its service life is very long. The rodless cylinder can run smoothly for many years by simply maintaining it regularly.
Compact Size
Obviously, the space at the train door of the train is very narrow, which makes the advantages of rodless compact cylinder more obvious, because rodless cylinder is very suitable for installation in a narrow space. The rodless hydraulic cylinder does not need additional space when controlling the opening or closing of the train door. It is calculated that if all train doors are driven by rodless cylinders, the body of the train can be shortened by up to 45%.
Versatile
When the train door is opened or closed, the door only needs to make a simple linear movement, and the rodless tailgate cylinder is very suitable to provide power for this movement. In other words, manufacturers can customize the length of the buffer area inside the cylinder according to the weight of the door and the running speed of the train. This makes the door more stable and smooth when opening or closing.
Safe
The train driver and crew must consider the safety of passengers. If passengers or other objects such as luggage compartment interfere with the opening or closing of the door, the door controller and rodless guide cylinder can reduce the driving force faster and safer, so as to avoid passengers being clamped by the door.
