(Croatia unidirectional cylinder,produced by Hebei Hengyu company）

unidirectional cylinder are widely used in Croatia，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed unidirectional cylinder for customers from Croatia.

Introduction to unidirectional cylinder:

unidirectional cylinder and hydraulic station selection: Select the type and structure of the unidirectional cylinder according to the operation requirements of the main engine. According to the external load force borne by the unidirectional cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the unidirectional cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the unidirectional cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the unidirectional cylinder, the diameter of the piston and the piston rod.

Classification of unidirectional cylinder: according to the mode of movement it can be divided into linear reciprocating movement type and rotary swing type; According to the effect of liquid pressure, it can be divided into single acting type and double acting type. According to the structure, it can be divided into piston type, plunger type, multistage telescopic sleeve type, pinion and rack type, etc. According to the installation form can be divided into rod, earring, foot, hinge shaft and so on; According to the pressure grade can be divided into 16Mpa, 25Mpa, 31.5Mpa and so on.

The coordination of the sliding parts of the unidirectional cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.

The difference between the integral unidirectional cylinder and the split unidirectional cylinder: The integral unidirectional cylinder and the split unidirectional cylinder in the unidirectional cylinder are two different unidirectional cylinders, and they are very different. The whole unidirectional cylinder, which is cast in one body, is not prone to problems such as oil leakage; The split unidirectional cylinder is welded twice, so if it is not handled well at the welding, it is prone to problems such as oil leakage and unidirectional cylinder damage. Therefore, it is obvious that the answer to this question is for difference.

Answers to some questions about unidirectional cylinder:

What is a two-way hydraulic cylinder?
Bidirectional hydraulic cylinder definition: The bidirectional hydraulic cylinder uses the oil as the working medium, transmits the movement through the change of the sealing volume, and transmits the power through the pressure inside the oil. The two-way cylinder has at least two oil ports, which are used to connect the hydraulic tubing, and control the extension and retraction of the cylinder by pressing.

How to set the stroke of the cylinder?
Self-design should be based on product demand and practical application. The stroke of standard cylinder depends on the parameters the customer requires. The hydraulic cylinder is a linear motion actuator whose output force is proportional to the effective area of the piston and the pressure difference on both sides. Its function is to convert hydraulic energy into mechanical energy. The input of the hydraulic cylinder is the flow rate and pressure of the fluid, and the output is the speed and force of the linear motion. The piston of the hydraulic cylinder can complete the linear reciprocating movement, and the linear displacement of the output is limited. Hydraulic cylinder is an energy conversion device that converts hydraulic energy into mechanical energy of reciprocating linear motion. The hydraulic cylinder is basically composed of cylinder body, cylinder head, piston and piston rod, sealing device, buffer device and exhaust device.
