(Pakistan stacker cylinder,produced by Hengyu Hydraulic Cylinder Factory）

stacker cylinder are widely used in Pakistan，because of clever hydraulic energy conversion，no transmission clearance，powerful torque.So our company has designed stacker cylinder for customers from Pakistan.

Introduction to stacker cylinder:

How to repair the stacker cylinder body when it is damaged: When the stacker cylinder has trace deformation and shallow tensile marks, the stacker cylinder is repaired by strong honing process. The heavy honing process can repair stacker cylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the stacker cylinder can meet the technical requirements.

The assembly work of the stacker cylinder has a great impact on the quality of the stacker cylinder: each part must be carefully cleaned before assembly; To correctly install the sealing device everywhere: when installing the sealing ring, pay attention to its installation direction to avoid oil leakage due to installation, and its lip should be equipped with a pressure oil chamber. In addition, because it is a YX-shaped sealing ring, it is necessary to pay attention to distinguish between shaft and hole use, do not install wrong; Because the sealing device is matched with the sliding surface, an appropriate amount of hydraulic oil should be applied during assembly; The special wrench should be used when the threaded coupling is tightened, and the torque should meet the standard requirements; After the piston and piston rod are assembled, it is necessary to measure whether the coaxiality and straightness on the full length are out of whack. After assembly, there should be no blocking sensation and uneven resistance when the piston assembly moves.

There are some honeycomb holes in the inner wall of the stacker cylinder, piston or piston rod surface. How is this formed? When we repair the stacker cylinder, we can see that there are some honeycomb holes on the inner wall of the stacker cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the stacker cylinder is targeted to prevent. Is very necessary.

Do not enter foreign bodies when installing the stacker cylinder block. The place where the installation operation is carried out, the conditions are not good, and foreign bodies can be entered unconsciously. Therefore, the installation site must be cleaned up around, especially the place where the parts are placed must be cleaned, so that there is no dirt.

Answers to some questions about stacker cylinder:

How to set up the one-way cylinder hydraulic system?
Single acting oil cylinder, that is, an oil cylinder with an oil port, can use two three-way valves to control the cylinder action. The three oil ports are respectively connected to P (oil pump), A (oil cylinder), and T (oil tank). If the oil pump is to run continuously, an electromagnetic relief valve can be added. When the cylinder is not moving, the relief valve can unload the oil pump. You can also add a three-way four-way valve, the middle function is unloaded, two outlets: A connected to the fuel tank, B connected to the cylinder.

Two cylinders have a reversing control, if the load of the two cylinders is not the same, how to ensure their synchronization?
The piston rod of the cylinder is required to extend synchronization: install A shunt collector valve or synchronous motor at port A of the direction control valve, and then connect the two outlets of the shunt collector valve to the rod-free cavity of the two cylinders respectively. It is required that the outlet of the diverter collector valve is connected to the rod cavity of the two cylinders respectively when the piston rod is withdrawn in synchronization. The synchronization performance depends on the quality of the diverter valve and the leakage of the hydraulic system.
