(Nigeria stacker cylinder,produced by Hengyu Hydraulic Co., Ltd）

stacker cylinder are widely used in Nigeria，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed stacker cylinder for customers from Nigeria.

Introduction to stacker cylinder:

The advantages and disadvantages of the stacker cylinder: the surface of the stacker cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the stacker cylinder through the top heat treatment, high manufacturing precision, belongs to the precision machinery, has a simple structure, stable quality, high mechanical efficiency, easy to achieve automation and many other advantages. However, hydraulic technology also has the shortcomings of oil leakage, oil temperature change affecting the control of running speed, noise, expensive cost and high maintenance cost.

The definition of the minimum starting pressure of the stacker cylinder refers to the minimum working pressure of the stacker cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the stacker cylinder parts and the size of the sealing friction.

stacker cylinder installation precautions: Before installing the stacker cylinder into the system, the parameters on the stacker cylinder label should be compared with the parameters when ordering. The base of the stacker cylinder must have sufficient stiffness, otherwise the stacker cylinder will bend upward into a bow when pressurized, so that the piston rod will bend.

When the stacker cylinder thrust is insufficient, check the hydraulic circuit for leaks. Including leakage of valves and hydraulic lines. The inspection method is to check and eliminate the leakage of the hydraulic connection line by manipulating the reversing valve. Also consider the relief valve. If the relief valve enters the dirt and jams the spool, so that the relief valve is normally open, the hydraulic oil will flow directly back to the tank through the relief valve bypass, resulting in no oil in the stacker cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the stacker cylinder still cannot get the thrust required for continuous action without action. If the regulating pressure is low, the pressure is insufficient to achieve the required vertebra force, which is manifested as insufficient thrust. Check and adjust the relief valve at this time.

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.

How to achieve hydraulic cylinder self-locking?
Hydraulic cylinder self-locking is divided into oil self-locking and mechanical self-locking. The oil self-locking is equipped with a valve to maintain pressure, so that the hydraulic oil of the cylinder does not return to the tank, and the oil chamber of the cylinder is filled with a certain pressure of oil. However, this pressure holding self-locking is not very safe and reliable, and the plunger will slowly return if there is a leak. Mechanical self-locking is to install a nut on the plunger of the cylinder, and when the cylinder rises to the required position, the nut on the cylinder plunger is rotated to the end, and the cylinder block is in contact, so that the plunger will be fixed to the required height. When it is necessary to relieve the pressure, screw the nut on again and let the plunger return to the position. This kind of cylinder has a special name, called self-locking hydraulic cylinder.
