Colombia hydraulic cylinder,series synchronous cylinder manufacturer,series synchronous cylinder

(Colombia series synchronous cylinder,produced by Hebei Hengyu company）

series synchronous cylinder are widely used in Colombia，because of excellent temperature resistance，no need for deceleration device，long service life.So our company has designed series synchronous cylinder for customers from Colombia.

Introduction to series synchronous cylinder:

Piston series synchronous cylinder is widely used in hydraulic transmission. When the series synchronous cylinder works, it mainly delivers hydraulic oil alternately to both sides of the piston in the series synchronous cylinder, and uses the pressure difference of hydraulic oil on both sides of the piston to realize the reciprocating movement of the piston. If you want to speed up the forward speed of the piston, the return oil in the series synchronous cylinder can be controlled by the valve and directly input into the inlet pipe to participate in the work of the piston to achieve rapid movement of the piston, but the thrust of the piston is reduced much.

When the series synchronous cylinder is in use, once the seal and guide support ring are found to be defective, the seal with the same structural form and appropriate material should be replaced according to the structural form of the series synchronous cylinder seal to be repaired, so as to minimize the thickness of the oil film between the seal and the sealing surface and reduce the leakage of the seal.

The piston rod and guide sleeve function of the series synchronous cylinder is crucial: the relative motion pair between the piston rod and the guide sleeve is the main factor causing external leakage, if the chrome layer on the surface of the piston rod is spalling or producing longitudinal tensile marks due to wear, it will directly lead to the failure of the seal.

If it is found that the series synchronous cylinder lubrication is poor or the series synchronous cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the series synchronous cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the series synchronous cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the series synchronous cylinder center line. In this way, when the piston works in the series synchronous cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the series synchronous cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

Answers to some questions about series synchronous cylinder:

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.

About the hydraulic cylinder wall thickness problem?
Hydraulic cylinder wall thickness calculation formula: t=PD/200St= pipe wall thickness (minimum thickness) mmP= maximum pressure kg/cm2? d= inner diameter mm? S=δ/5 safety factor δ= minimum tensile strength This case: set the cylinder material 45#, tensile strength 58kg/cm2t=(640X40)/(200X11.6)t=11mm piston output (i.e. Thrust) calculation formula: F1=PD2X(3.14/4)F1=640X42X0.785=8,038kg Note: Square numbers will not be used, all 2's in the text are square codes.
