(Peru yg series hydraulic cylinder,produced by Hengyu Group）

yg series hydraulic cylinder are widely used in Peru，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed yg series hydraulic cylinder for customers from Peru.

Introduction to yg series hydraulic cylinder:

When the yg series hydraulic cylinder is disassembled due to oil leakage and other faults, the position of the piston should be moved to any end position of the yg series hydraulic cylinder by applying liquid pressure. Improper tapping and sudden drop should be avoided during disassembly.

The "O" ring can be used as an auxiliary seal inside the yg series hydraulic cylinder, and the elastic force of the "O" ring makes the sealing slip ring close to the sealing surface, generating sealing pressure to achieve sealing. When the internal hydraulic pressure increases, the "O" ring will further deform and squeeze the slip ring, thereby increasing the sealing pressure and improving the sealing performance. The structure has the characteristics of low friction coefficient, good wear resistance, automatic compensation for wear and absorption of hard particles in the yg series hydraulic cylinder, and can be completely sealed.

Under normal circumstances, the yg series hydraulic cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the yg series hydraulic cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the yg series hydraulic cylinder and the end cover, the piston and the piston rod, the piston and the yg series hydraulic cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the yg series hydraulic cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.

Repair method of small range wear of oil yg series hydraulic 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.

Answers to some questions about yg series hydraulic cylinder:

What material is the piston rod of the cylinder made of?
About the piston rod: ① Piston rods are usually made of 45# steel. When there is a large impact force and heavy load transmission, it is made of 40Cr steel. This is to ensure that the piston rod has sufficient working strength. ② The piston rod is generally designed as a cylinder, if the diameter is larger, the hollow piston rod can be used with 45# seamless steel pipe. ③ When the piston rod is manufactured, the blank should be first forged and conditioned after mechanical rough processing, and the hardness of HB=230 ~ 250. The purpose of conditioning is to improve the machining performance and increase the working strength of the material. ④ The surface roughness Ra of the piston rod after finishing should not be greater than 0.65μm. ⑤ In order to improve the corrosion resistance of the piston rod, the rod surface needs to be chrome plated.

How to deal with the surface degreasing process before spraying paint after cylinder assembly, and what degreasing agent is used?
Cylinder painting, generally using the following process (note: the cylinder is best painted, do not spray powder coating, because the powder coating curing temperature is high, will lead to sealing defects and oil leakage) : Pre-degreasing - degreasing - washing - washing - pickling - washing - washing - table adjustment - phosphating - washing - washing - drying - polishing - spray primer - spray paint degreasing agent generally use neutral or weak alkaline degreasing agent, phosphating liquid generally use zinc phosphating liquid.
