Structure And Application Of Hydraulic Oil Cylinder

       The hydraulic oil cylinder is composed of two parts: the host and the control mechanism. The main part of the oil cylinder includes the fuselage, the main cylinder, the ejection cylinder and the liquid filling device. The power mechanism is composed of an oil tank, a high-pressure pump, a low-pressure control system, a motor, various pressure valves and directional valves. Under the control of the electrical device, the power mechanism realizes the energy conversion, adjustment and transmission through the pump, the oil cylinder and various hydraulic valves, and completes the cycle of various technological actions. The working mode of hydraulic cylinder is reciprocating motion. The production of oil cylinders and fasteners is in the mechanical manufacturing industry, and the production of seals is generally in the chemical industry. The problem I want to elaborate is that the companies that produce oil cylinders and pistons do not necessarily have a clear understanding of the production technology of seals, and vice versa. However, the manufacturer of the cylinder must understand the sealing technology, and the manufacturer of the seal must also understand the working principle of the cylinder. Only when the two closely cooperate can a good hydraulic cylinder assembly be produced.
　　The hydraulic oil cylinder is mainly used for the place that needs to support heavy objects for a long time. It can still support heavy objects when the oil pressure is removed, and it is safe and reliable. It can be used underwater, single-acting, load retraction, nut self-locking makes the load safer, especially in large projects, it is easy to operate and control and self-locking jack, designed with a safety pressure-retaining device, built-in pressure relief valve to prevent overload, To protect the self-locking jack to facilitate safe operation. The input quantity of the hydraulic cylinder is the flow rate and pressure of the fluid, and the output is the linear movement speed and force. The piston of the hydraulic cylinder can complete linear reciprocating motion, and the output linear displacement is limited. A hydraulic cylinder is an energy conversion device that converts hydraulic energy into mechanical energy in a reciprocating linear motion. The hydraulic cylinder is basically composed of a cylinder barrel and a cylinder head, a piston and a piston rod, and a sealing device.
