(Republic of Lithuania reciprocating cylinder,produced by Hengyu Hydraulic Cylinder Factory）

reciprocating cylinder are widely used in Republic of Lithuania，because of no transmission clearance，simple structure and reliable operation，excellent temperature resistance.So our company has designed reciprocating cylinder for customers from Republic of Lithuania.

Introduction to reciprocating cylinder:

When the hydraulic oil is not pumped into the reciprocating cylinder, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the reciprocating cylinder to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.

reciprocating cylinder abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the reciprocating cylinder is placed for a period of time, the reciprocating cylinder may enter the air, and the movement can be normal after dozens of repeated movements. If it still cannot be eliminated, check whether the load is aligned with the axis of the piston rod; Retracted piston rod installation helps to align the load with the piston rod. If the flow is unstable, it will also lead to abnormal movement of the piston rod. Check the relevant components of the hydraulic system.

The coordination of the sliding parts of the reciprocating 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 reciprocating cylinder is mainly composed of body, piston, piston rod, reciprocating cylinder head, reciprocating cylinder bottom, piston rod head and related auxiliary devices. The piston divides the reciprocating cylinder into two chambers, and moves reciprocally in the reciprocating cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the reciprocating cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the reciprocating cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the reciprocating cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the reciprocating cylinder bottom and the reciprocating cylinder head is serious, so the buffer deceleration should be set at both ends of the reciprocating cylinder The working medium of the reciprocating cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; reciprocating cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the reciprocating cylinder: The buffer structure of the reciprocating cylinder is to prevent the piston from colliding with the reciprocating cylinder head at the end of the stroke.

Answers to some questions about reciprocating cylinder:

What is the rated pressure of the general cylinder?
This depends on the model of the cylinder, 1. The rated pressure of the light tie rod cylinder is 7 series 7MPa and 14 series 14MPa. 2. Rated pressure of engineering cylinder 16MPa. 3. Rexroth type metallurgical cylinder rated pressure 250MPa.

By what means can the hydraulic system control the arbitrary stroke position of the rotary cylinder piston rod?
The following ways can be considered: 1, through the limit device, such as limit switch, position sensor, etc. 2, by feedback the pressure of the hydraulic oil in the cylinder. The load determines the pressure, the pressure in the cylinder is determined by the load, and the pressure is very small when the cylinder is unloaded. 2.1 When clamping the workpiece, the pressure of the cylinder increases, by calculating the relationship between the clamping force and the pressure of the cylinder, take a pressure value of the cylinder, set the pressure switch, and drive the valve to work when the pressure reaches the preset value, so that the oil circuit stops supplying oil. 2.2 or set the pressure value of the relief valve to overflow after a certain set pressure.
