The bellow cylinder works as an actuator used in the process of dehydration of the sludge from water treatment plants.
The bellow cylinder’s function is very similar to the paper machine application or the juice processing machine. Bellow cylinders are placed to make a function of an air actuator, being able to tense the web that carries the sludge. Depending on the amount of sludge on the belt, the bellow cylinder expands or contracts itself, while the water and the sludge flow is controled by the system applied in the bellow cylinder.
Bellow cylinder vs pneumatic actuator
The bellow cylinder has remarkable performance. Compared to the pneumatic actuators, the elastomer does not require any lubrication, for this reason, it does not matter if the bellow cylinder is in the same position during a long time. In case of pneumatic actuators, if they are not changing their position during a certain period, this might be an issue, as the humidity and the lack of movement could affect the pneumatic actuator function in the system, taking into account that pneumatic actuators require lubrication and more frequent maintenance.
