What Do You Know About Cylinder

Source:http://www.flowxgroup.comUpdate Time:2014-11-10Hits:

It is maybe known to many people that cylinder is of great significance during the work of pneumatic actuators for its specific function. The compressed air pressure can be transformed into mechanical energy, driving mechanism as a straight line reciprocating movement, swinging and rotational movement of the components which is called the pneumatic actuators by people. In pneumatic actuators, the linear motion of the cylinder is mainly used.

According to the compression of the air pressure into force different parts of the structure, there are a piston and a piston. In actuator parts, diaphragm cylinder has goof function of sealing, no friction, no lubrication, but it strikes short, and mostly used in the production process control in clamping and open and close of valves, etc. The piston cylinder is the widely used.

There are a variety of the cylinders among actuator parts. The classification of the cylinder is:

According to the function, it is divided into standard, space saving type, high precision, stockless type, with guide rod type, valve type, measuring type, etc.

According to the size, it can be divided into miniature cylinder, small cylinder, medium cylinder, large cylinder. Under the condition of same diameter, the diameter of piston rod and piping interface size also are associated with the variety of the cylinder.

Cylinder stroke can also divide into standard stroke, long stroke and the maximum stroke. Standard trip refers to the trip which does not need special order to the manufacturer. The scope of the standard stroke is associated with the form of cylinder and the cylinder diameter size. Non-standard stroke is called a special trip to organize production according to special order.

Furthermore, as an important part of pneumatic actuators, complying with the way of install, cylinder can also be divided into several types. Firstly, let’s go into it according to the buffer methods of classification. Piston movement of the visit terminal velocity is large. In order to prevent the piston impact end covering cylinder damage as well as reduce the impact noise, there usually is a buffer in the terminal of cylinder stroke. Buffer can be divided into single pole side or stockless side buffer and buffer on both sides, fixed buffer (such as cushion, fixed orifice) and adjustable buffer (such as buffer valve).

Additionally, according to the electric actuators method, it can be divided into the oil and gas cylinder. For oil and gas cylinder is made of compressed air into the oil mist, relative motion within the cylinder for lubrication. Not to oil and gas is refers to the compressed air in cylinder oil mist. Compared with the relative motion of adding grease lubrication, it is to rely on the sealing ring in advance to guarantee its work. In addition, the components which are used in the cylinder are not easy to rust.
