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

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

Introduction to yg series hydraulic cylinder:

Before the yg series hydraulic cylinder is removed, the relief valve should be loosened to reduce the pressure of the hydraulic circuit to zero, and then the power supply should be cut off to stop the hydraulic device. After loosening the oil port piping, the oil plug should be applied to plug the oil port.

The quality of the yg series hydraulic cylinder can not be ignored in the purchase of the yg series hydraulic cylinder. The yg series hydraulic cylinder is the main component of the yg series hydraulic cylinder, the single pillar for mining, the hydraulic support, the gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. yg series hydraulic cylinder processing requirements are high, its internal surface roughness requirements are Ra0.4 ~ 0.8μm, the coaxiality, wear resistance requirements are strict. The basic feature of yg series hydraulic cylinder is deep hole processing, which has always troubled the processing personnel.

yg series hydraulic cylinder piston rod material selection and technical requirements: (I), because there is no special requirements, so use 45 steel as the piston rod material, the design of the piston rod only withstand pressure stress, so no modulation processing; (ii) The coaxial tolerance of the shaft journal and the outer circle of the mounting piston is not greater than 0.01mm, so as to ensure the coaxial degree of the outer circle of the piston rod and the outer circle of the piston, and avoid the stuck phenomenon of the piston and the yg series hydraulic cylinder, the piston rod and the guide. The vertical tolerance between the end face of the mounting piston and the axis of the piston rod is not more than 0.04mm/100mm to ensure that the piston installation does not produce skew; (iii) The outer circle of the piston rod should pay attention to the roughness; (iv) Because it is operated under low load conditions, surface treatment is omitted.

When installing the yg series hydraulic cylinder, the axial ends of the yg series hydraulic cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the yg series hydraulic cylinder, there is axial expansion. If the two ends of the yg series hydraulic cylinder are fixed, all parts of the yg series hydraulic cylinder will be deformed. When disassembling the yg series hydraulic cylinder, it is strictly forbidden to hammer the yg series hydraulic cylinder and the piston surface, such as the yg series hydraulic cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.

Answers to some questions about yg series hydraulic cylinder:

Is the hydraulic cylinder leaking because there is no pressure?
HC hydraulic cylinder common leakage reasons, first: most of the reasons are because the seal surface wear or aging leads to poor sealing, so there is no pressure to operate, as long as the piston seal can be replaced. Second: It may also be the piston rod strain, repair the piston rod is good. If it is because the piston strength is not enough and the playing time is long, it is necessary to replace the piston.

What is hydraulic cylinder guide?
The cylinder itself can not move, the piston moves, the guide should be used to guide the mechanism connected with the piston extension end. For example, in the commonly used hydraulic press, the guide column above is used to guide the pressure plate connected with the piston.
