(Azerbaijan hydraulic servo cylinder,produced by Hebei Hengyu company）

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

Introduction to hydraulic servo cylinder:

When the piston speed of the hydraulic servo cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the hydraulic servo cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.

Repair method of small range wear of oil hydraulic servo cylinder: 1. Use oxygen-acetylene flame to bake the scratched part (master the temperature, avoid surface annealing), bake the oil on the metal surface all the year round until no sparks splash; 2. The scratched part is treated with an Angle grinder, the grinding depth is more than 1 mm, and the groove is polished along the guide rail, preferably a dovetail groove. Scratch both ends of the drilling deeper, change the force situation; 3. Clean the surface with absorbent cotton dipped in acetone or anhydrous ethanol.

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

If the hydraulic servo cylinder slips or crawls, please check whether there is astringency inside the hydraulic servo cylinder, because the internal parts of the hydraulic servo cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, the action resistance is too large, so that the piston speed of the hydraulic servo cylinder changes with the different stroke position, and the slip or crawl occurs. Most of the reasons are due to poor assembly quality of parts, surface scars or sintered iron filings, so that the resistance increases, the speed decreases. For example, the piston is different from the piston rod or the piston rod is bent, the hydraulic servo cylinder or the piston rod is offset from the mounting position of the guide rail, and the sealing ring is too tight or too loose. The solution is to repair or adjust, replace damaged parts and remove iron filings.

Answers to some questions about hydraulic servo cylinder:

Hydraulic system schematic diagram, pipeline identification S and L, respectively corresponding nominal diameters? 16S is equivalent to DN12 high-pressure cylinder, and 15L means what?
16S refers to the high pressure series, outer diameter 16x2 steel pipe, the corresponding sleeve nut is M24X1.515L is the low pressure series, the outer diameter of 15x1.5 steel pipe, the corresponding sleeve nut is M22X1.5.

How to distinguish large cavity and small cavity of excavator rod cylinder ?
Single rod piston cylinder is a form of cylinder that is used relatively most, and the boom, bucket, dozer shovel cylinder are all in this form. Among them, the rodless cavity is also called the large cavity, and the rodless cavity is also called the small cavity. Therefore, the cylinder cavity on the side with the exposed piston rod is the small cavity, and the cylinder cavity on the side without the exposed rod is the large cavity.
