What is an air roller?
Air cylinder is usually a cylindrical or tube that contains shaft, piston and rod. There are other shapes and sizes, but the tube -shaped version is the most common.
The rod inside the air cylinder fits in the shaft and is able to move freely in and out. Pluntár is connected to the end of the rod and cannot be seen. The purpose of the piston is to take the pressure of the air pressure flowing in the cylinder. The wider straight surface of the piston provides a wall that pushes the air pressure.
There are two main types: the only acting and double acting. One acting pushes when the spring returns the rod to the shaft. The double -acting air cylinder moves the rod in and out due to air pressure at one end, creating a vacuum at the other end. Vacuum pulls the rod back into the shaft.
Air cylinders have many uses. They are found in cars, houses, hospitals and businesses. How one is used by its evaluation. It is evaluated on the basis of three things: pressure, opening and stroke.
pressure isDetermination of the safest pounds on a square inch (dogs) can handle the air cylinder load. VRT is the diameter of the cylinder on the inside of the shaft. Finally, the stroke is the distance or length that the rod can move inside the shaft without setting off or bending the piston inside.
The air cylinder is used to control air brake pressure to 18-round. It is also used to help the car engine push the pistons, which in turn helps to turn the crankshaft, causing the tires to rotate. One can also help close certain types of doors. Many of these actions take place without visible, so it can be difficult for a beginner to understand.
The most common example of the air cylinder is a tube -shaped device that helps open the storm door and close. As a person pushing the storm -opening, the rod inside the shaft is stretched and the cylinder uses the inflow of air to help pushrod along. When the door is released, the air flows back from the cylinder. The genus is distance and moves back into the shaft and the door is closed. This is the perfect example of a double -acting air cylinder.
