stacker cylinder are widely used in Vietnam，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed stacker cylinder for customers from Vietnam.

Introduction to stacker cylinder:

When the stacker cylinder is in use, measures should be added to prevent the intrusion of pollutants. Effective measures should be taken to control the intrusion of pollutants, such as installing high-efficiency air filters in the tank breathing holes, new oil must be filtered, etc., but also must improve the anti-pollution ability of the stacker cylinder itself. In the seriously polluted environment, it is more important to pay attention to, such as the underground oil stacker cylinder should use fluorine rubber (FRM) and nitrile rubber (NBR) dust ring, and the ground mechanical stacker cylinder should use nitrile rubber dust ring; The filter device is added to the oil inlet of the stacker cylinder of the dump truck, construction machinery, work platform and other equipment, and in order to reduce the oil inlet resistance, the flow area should be increased as much as possible, which can effectively reduce the particle pollution from the system.

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 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.

The material of the sliding part of the stacker cylinder piston sintered casting piston will cause sintering phenomenon when subjected to large transverse load. In this case, the sliding part of the piston should be made of copper alloy or welded to such material.

Answers to some questions about stacker cylinder:

How to design the guide sleeve of cylinder diameter 400?
The purpose of the guide sleeve is to guide and seal. Therefore, it is necessary to look at the speed of the piston rod, working pressure and radial force. High speed, medium pressure, no (or very little) radial force, with a Steseal. Low speed and heavy load, medium radial force, combined seal. High speed and heavy load, large radial force, sealed with DU sleeve + copper ring + combination. The combination seal must have a lubricating oil passage, and a seal must be added to the outside of the oil passage.

Why are the hydraulic cylinders out of sync? The reasons for the unsynchronous operation are as follows: 1, the deviation of the external load of the two cylinders, such as the different resistance and friction of the two cylinders will lead to imbalance. The displacement of the cylinder with low resistance will be larger. 2, the difference in internal friction, such as the difference between the piston and the cylinder of each cylinder, the friction between the piston rod and the seal causes the cylinder to be out of sync. 3. The different resistance of hydraulic oil along the pipeline of the two cylinders causes the cylinder to be out of sync. 4, the deviation of the control original adjustment causes the deviation of the flow to be out of sync, such as the use of an independent throttle valve for each cylinder will appear the difference in the flow of oil in and out of the oil affecting the synchronization of the two cylinders. 5. The cylinder support point of the supported part is initially different.
