(Bangladesh yg series hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）

yg series hydraulic cylinder are widely used in Bangladesh，because of no need for deceleration device，long service life，smooth movement.So our company has designed yg series hydraulic cylinder for customers from Bangladesh.

Introduction to yg series hydraulic cylinder:

yg series hydraulic cylinder use should try to avoid sealing belt into the yg series hydraulic cylinder. As a simple sealing material, polytetrafluoroethylene plastic sealing tape is often used in installation and inspection, and if the winding method of the linear and ribbon-shaped sealing material is wrong, the sealing tape will be cut off and enter the yg series hydraulic cylinder. The wire belt seal will not have any effect on the winding of the sliding part, but it will cause the check valve of the yg series hydraulic cylinder to fail to operate or the buffer regulating valve can not be adjusted to the end. For the circuit, it may cause the action of the reversing valve, the relief valve and the reducing valve to fail.

The scar on the sliding surface of the yg series hydraulic cylinder piston will transfer with use. Before the piston is installed, there are scars on its sliding surface, which are installed intact and untreated, and these scars will in turn scratch the inner surface of the yg series hydraulic cylinder wall. Therefore, before installation, these scars must be fully repaired.

What kind of process is used in the yg series hydraulic cylinder to make high-quality yg series hydraulic cylinder products: the body is the main component of the yg series hydraulic cylinder, mining single pillar, hydraulic support, gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. Body processing requirements are high, the internal surface roughness requirements are Ra0.4 ~ 0.8&um, the coaxiality, wear resistance requirements are strict. The basic feature of body is deep hole processing, which has always troubled the processing personnel. The yg series hydraulic cylinder products of our company mainly use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface micro-cracks and hinder the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the body can be improved. The correct rolling process of the yg series hydraulic cylinder block: broaching block - fine boring block - grinding block. The rolling method is: broaching block - fine boring block - rolling block, the process is 3 parts, but the time is compared: grinding 1 meter of the block is about 1-2 days, rolling 1 meter of the block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3um before rolling to RA0.4-0.8&um, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the yg series hydraulic cylinder increases by 25%. If the service life of the yg series hydraulic cylinder is only considered, it is increased by 2 to 3 times, and the efficiency of the boring and rolling process is about 3 times higher than that of the grinding process. yg series hydraulic cylinder misoperation or operation failure may be caused by the following reasons, you can start from these aspects of the investigation: (1) spool stuck or valve hole blocked. When the spool of the flow valve or direction valve is stuck or the valve hole is blocked, the yg series hydraulic cylinder is prone to misoperation or operation failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium. (2) The piston rod and yg series hydraulic cylinder are stuck or the yg series hydraulic cylinder is blocked. At this time, no matter how to manipulate, the yg series hydraulic cylinder does not move or moves very little. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the yg series hydraulic cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

When the yg series hydraulic cylinder is installed on the main engine, the oil port piping part and the guide sleeve should be checked for oil leakage in the running test, and the earring and the middle hinge shaft bearing should be refueled.

Answers to some questions about yg series hydraulic cylinder:

Do the collecting cylinder, distributing cylinder and distributing cylinder on the organic heat carrier boiler need to be notified separately as the pressure vessel for construction?
Do not need to be installed as a separate pressure vessel to inform, according to the organic heat carrier boiler can be informed. Write a "special equipment installation, renovation and maintenance notice" issued on it.

What is the cylinder with rod cavity, what is the rodless cavity.
The rod cavity is the end of the piston rod, the rodless cavity is the end without the piston rod.
