synchronous hydraulic cylinder are widely used in Finland，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed synchronous hydraulic cylinder for customers from Finland.

Introduction to synchronous hydraulic cylinder:

synchronous hydraulic cylinder hydraulic oil selection: The recommended working oil viscosity of the synchronous hydraulic cylinder is 10 ~ 110cSt (1.8 ~ 15E), ISO VG46 hydraulic oil. The normal working oil temperature is 10 ~ 70℃, and the ambient temperature is in the range of -20 ~ 80℃. When the ambient temperature and service temperature are low, the hydraulic oil with lower viscosity can be selected.

The synchronous hydraulic cylinder is mainly composed of body, piston, piston rod, synchronous hydraulic cylinder head, synchronous hydraulic cylinder bottom, piston rod head and related auxiliary devices. The piston divides the synchronous hydraulic cylinder into two chambers, and moves reciprocally in the synchronous hydraulic 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 synchronous hydraulic cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the synchronous hydraulic 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 synchronous hydraulic 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 synchronous hydraulic cylinder bottom and the synchronous hydraulic cylinder head is serious, so the buffer deceleration should be set at both ends of the synchronous hydraulic cylinder The working medium of the synchronous hydraulic cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; synchronous hydraulic 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 synchronous hydraulic cylinder: The buffer structure of the synchronous hydraulic cylinder is to prevent the piston from colliding with the synchronous hydraulic cylinder head at the end of the stroke.

synchronous hydraulic cylinder abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the synchronous hydraulic cylinder is placed for a period of time, the synchronous hydraulic 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 meaning of the synchronous hydraulic cylinder model marked by the synchronous hydraulic cylinder manufacturer: for example, 160/100-1150, its meaning: from a professional point of view, 160 refers to the synchronous hydraulic cylinder diameter, which is 160mm, and the 100 behind refers to the rod diameter, which is 100mm. The 1150 refers to the synchronous hydraulic cylinder stroke, which is 1150mm. Therefore, on this point, we should have a correct understanding and can not make mistakes.

Answers to some questions about synchronous hydraulic cylinder:

When there is only one hole in the oil inlet and outlet of the hydraulic cylinder, will there be oil leakage?
It is a single acting oil cylinder. This oil cylinder is always driven by hydraulic oil in advance, and is generally pulled back by the spring at the bottom of the piston or the weight of the cylinder piston or the load. But either way, it has nothing to do with any internal leakage. Whether the oil is internally drained is related to the sealing and accuracy of the cylinder itself.

What is the difference between hydraulic piston cylinder and plunger cylinder?
The force surface of the piston cylinder is a rod cavity and a rodless cavity, and the force surface of the plunger cylinder is the plunger, the spring return single-acting piston cylinder can also rely on the external force of the spring to achieve return, the double-acting piston cylinder can produce tension, and the plunger cylinder only produces thrust without tension.
