(Costa Rica stacker cylinder,produced by Hengyu Hydraulic Cylinder Factory）

stacker cylinder are widely used in Costa Rica，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 Costa Rica.

Introduction to stacker cylinder:

The commonly used buffer structure of the stacker cylinder is composed of a piston boss and a stacker cylinder head groove. When the piston moves close to the stacker cylinder head, it gradually enters the groove, and the oil in the groove is extruded through the gap between the boss and the groove, which increases the oil return resistance, produces the braking effect and realizes the buffer. Generally, a buffer mechanism should be used when the pressure is above 10MP.

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.

stacker cylinder seal leakage causes and countermeasures: a. Loose tie rod nut will cause leakage, tighten the tie rod nut according to the torque requirements of tie rod nut, test no leakage can continue to use. b. Pressure exceeding the limit will also cause leakage. Replace the stacker cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the stacker cylinder. c. The stacker cylinder seal is extruded, if the O-ring is obviously extruded at the stacker cylinder seal, replace the stacker cylinder seal.

stacker cylinder to reasonable use of hydraulic oil: strict hydraulic oil selection off. Hydraulic oil is selected in strict accordance with oil standards. The selection of good quality hydraulic oil can effectively prevent bubbles in the working process of the hydraulic system. When choosing the oil, it should be selected according to the lowest temperature in different regions, and fill the hydraulic oil according to the dipstick standard, and at the same time, it should also keep the hydraulic system clean (when filling the hydraulic oil, it should prevent the water and other impurities into it), and often check the oil quality, oil level and oil color of the hydraulic oil. If blisters and bubbles are found in the hydraulic oil. When the oil becomes milky white, the source of the air in the oil should be carefully found and eliminated in time.

Answers to some questions about stacker cylinder:

How to calculate the tonnage of hydraulic cylinder? The tonnage of the cylinder refers to the output force of the cylinder under rated working pressure: 1, for single rod piston hydraulic cylinder, it can be calculated by the area of the circle corresponding to the inner diameter of the cylinder A (square centimeter), and the rated working pressure of the system p (mpa), the value is equal to 10pA kg force, and the ton is 0.01pA. 2, for the double rod piston hydraulic cylinder, with A(square centimeter) to indicate the cylinder cylinder diameter and piston rod outer diameter defined by the ring area, with p (mpa) to indicate the rated working pressure of the system, the output force of the cylinder is 0.01pA ton force.

How to judge the failure of forklift hydraulic cylinder?
The common faults of the hydraulic cylinder of forklift truck are mainly crawling, insufficient thrust, working speed decline or even stop. Generally, crawling occurs at low speed. The main reason is that the air stored in the cylinder is not cleared. In addition, excessive or uneven mechanical friction can also cause crawling. Such as the piston and the piston rod different heart, the piston rod full length or local bending, the cylinder hole straightness is poor, the cylinder is drum shaped or has a large taper, the cylinder thin finish decline or produce hair, the cylinder installation accuracy is out of whack, the piston rod nuts at both ends of the screw too tight to make its concentricity is poor, the oil seal screw too tight friction is too large, will cause crawling.
