Type:
Pneumatic cylinder: The use of compressed air as a power source, through the expansion and contraction of the gas to generate motion.
Hydraulic cylinder: The use of liquid (usually hydraulic oil) as a power source, through the flow of liquid and pressure to produce motion.
Application Areas:
Pneumatic cylinder: widely used in automation systems, manufacturing equipment, packaging machinery and other fields.
Hydraulic cylinder: commonly used in heavy machinery, engineering equipment, ships, aviation and other applications that require large driving force.
Functional Features:
Driving force: The driving force generated by the cylinder depends on the pressure of the gas or liquid and the dimensions of the cylinder.
Linear motion: Mainly used to produce linear motion, but some designs can also be used for rotational motion.
Automation control: can be integrated with automation systems to achieve precise motion control by controlling the pressure of gas or liquid.
Structure and working principle:
Pneumatic cylinder: usually consists of cylinder body, piston, sealing element and cylinder head and tail. When compressed air enters the cylinder, it pushes the piston to produce a linear motion.
Hydraulic cylinder: it is composed of cylinder body, piston, sealing element and cylinder head and tail. When the liquid is pressed into the cylinder, the piston is pushed into linear motion.
Control mode:
Manual control: The movement of the cylinder is controlled by manual operation.
Automatic control: Automatic control of the cylinder is achieved through automated systems, sensors and controllers.
Security Considerations:
Some safety features such as overload protection, emergency stop system, etc. may be included in the design to ensure safe operation of the equipment.
Custom design:
Cylinders can often be custom-designed for specific application requirements to meet specific performance and operating conditions.
The choice of cylinder depends on the specific application requirements, including the required force, speed, type of motion, and environmental conditions.
