Maintenance And Upkeep Of The Pneumatic System Of A Mixer: Use And Maintenance Of The Cylinders.

The function of a pneumatic cylinder is to convert the pressure energy of compressed air into mechanical energy. Under normal circumstances, the cylinder should move quickly to its designated position with the switching on and off of the solenoid valve power supply.  Due to the repetitive movement of the cylinder piston, lubrication of the cylinder wall and piston is very important. Generally, a lubricator is used to atomize the lubricating oil and inject it into the airflow, which then carries the oil to the lubrication points. During operation, cylinders closer to the lubricator show better lubrication, while those further away show poorer lubrication. This is particularly evident in the cylinders of the aggregate bin. The solution is to add another lubricator in the middle of the aggregate bin's pneumatic circuit. A layer of grease can be applied to the piston rod to prevent corrosion. Common cylinder malfunctions include air leaks, which can be internal or external. Internal leaks occur when the cylinder piston assembly is severely worn, causing air to leak between the front and back of the piston, affecting the speed of the cylinder's movement and, in severe cases, preventing it from reaching its intended position. External leaks occur when the seals at the end of the piston rod in contact with the cylinder are severely worn, causing slow piston rod return speed or even failure to return to the correct position.
