(Libya double acting cylinder,produced by Hengyu Group）

double acting cylinder are widely used in Libya，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed double acting cylinder for customers from Libya.

Introduction to double acting cylinder:

double acting cylinder hydraulic oil selection: The recommended working oil viscosity of the double acting 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.

In the process of using the double acting cylinder, sometimes such a problem will occur, the double acting cylinder can not act immediately after the instruction of the double acting cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil double acting cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.

The internal leakage of the double acting cylinder is an important indicator to measure the quality of the double acting cylinder: the internal leakage of the double acting cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the double acting cylinder, so that the double acting cylinder can not accurately and stably stop in a certain position of the double acting cylinder, so it is one of the main indicators of the double acting cylinder.

We can not just consider the price and ignore the quality when we purchase the double acting cylinders. Now some manufacturers produce unqualified products in order to reduce costs, the piston rod is not adjusted, the rod coating is not enough, the double acting cylinder finish can not reach, the guide sleeve should use copper, but instead of ductile iron, although the cost is reduced, the quality of the double acting cylinder is not required.

Answers to some questions about double acting cylinder:

How to limit cylinder push rod rotation?
In general, the push-rod rotation can be limited after the push-rod is connected to the pushed mechanism. For example, the push rod is hinged with the push mechanism, or the push mechanism itself is guided, which can limit the rotation of the push rod.

How to control the speed of the cylinder?
High demand control, it is necessary to use servo closed-loop control, you can adjust the speed at will. Reference: Hydrodynamic Motion Control Practical Design Guide.
