Hydraulic cylinder introduce Hydraulic system It is composed of power unit, actuator (including auxiliary parts), control and regulation devices, etc. In the hydraulic system, the components that play the role of connection and conversion are called hydraulic pump and Hydraulic motor 。 According to different energy sources, it can be divided into two categories: electro-hydraulic servo system and internal combustion engine driven hydraulic system.

The hydraulic cylinder consists of two parts: the main engine and the control mechanism. The main engine part includes the engine body, the main cylinder, the ejection cylinder and the filling device. The power mechanism is composed of oil tank, high-pressure pump, low-pressure control system, motor, various pressure valves and reversing valve. Under the control of the electric device, the power mechanism realizes the conversion, adjustment and transmission of energy through pumps, oil cylinders and various hydraulic valves to achieve the cycle of various process actions. The working mode of hydraulic cylinder is reciprocating motion. Mechanical manufacturing industry produces cylinder fasteners, and chemical industry generally produces seals. The problem I want to explain is that the enterprises that produce oil cylinders and pistons do not necessarily understand the production technology of seals, on the contrary, they do. But the oil cylinder manufacturer must know the sealing technology, and the seal manufacturer must also know the working principle of the oil cylinder. Maybe only through close cooperation with each other can a good hydraulic cylinder assembly be made.

The selection of oil cylinder must meet various requirements of the customer, such as the installation method of the oil cylinder, the output size of the oil cylinder, and the stroke of the oil cylinder. The oil cylinder in different use environments should be customized according to the customer's requirements. For example, some high-temperature operating environments require the use of high-temperature seals, otherwise the oil cylinder will use only a few days and will directly inject oil. Sometimes the working environment of the user will also affect the service life of the oil cylinder. When the air pollution around the oil cylinder is very serious, I generally recommend changing the hydraulic oil half a year or once a year to ensure that the oil cylinder can be used for a long time.

The hydraulic cylinder is mainly used in places where heavy objects need to be supported for a long time. It can still support heavy objects without oil pressure, which is safe and reliable. Applicable to underwater, single acting, load retraction, self-locking nuts, making the load safer. Especially in large projects, it is a self-locking jack easy to operate and control. It is equipped with a safety pressure maintaining device and a built-in pressure relief valve to avoid overload, thus ensuring the safe operation of the self-locking jack. The input of the hydraulic cylinder is the flow and pressure of the fluid, and the output is the linear speed and force. The piston of the hydraulic cylinder can complete the linear reciprocating movement, and the output linear displacement is limited. Hydraulic cylinder is an energy conversion device that converts hydraulic energy into reciprocating linear motion mechanical energy. The hydraulic cylinder is basically composed of a cylinder barrel and a cylinder head, a piston and a piston rod, and a sealing device.
