Uganda unidirectional cylinder

(Uganda unidirectional cylinder,produced by Hengyu Hydraulic Cylinder Factory)

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

Introduction to unidirectional cylinder:

The internal leakage of the unidirectional cylinder is an important indicator to measure the quality of the unidirectional cylinder: the internal leakage of the unidirectional cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the unidirectional cylinder, so that the unidirectional cylinder can not accurately and stably stop in a certain position of the unidirectional cylinder, so it is one of the main indicators of the unidirectional cylinder.

The piston rod of the unidirectional cylinder has two kinds of solid rod and hollow rod, and one end of the hollow piston rod needs to be set aside for welding and heat treatment. The solid piston rod material is 35, 45 steel, and the hollow piston rod material is 35, 45 seamless steel pipe. After rough machining, the piston rod is conditioned to 229~285HB in India, and if necessary, the hardness is 45~55HRC after high-frequency quenching.

The unidirectional cylinder should be vented: when the unidirectional cylinder is installed or parked for a long time to work again, the air will penetrate into the unidirectional cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the unidirectional cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the unidirectional cylinder, the oil is best entered and discharged from the highest point of the unidirectional cylinder. unidirectional cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.

The body of the unidirectional cylinder on the processing process requirements: the body of the unidirectional cylinder is an important and essential part of the unidirectional cylinder, because it has an irreplaceable role. The processing requirements for this part are very high, requiring that the surface roughness of the unidirectional cylinder after processing should reach 0.4-0.8um, and the coaxiality and wear resistance requirements are also very high.

Answers to some questions about unidirectional cylinder:

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.

What are the main technical parameters of the hydraulic cylinder?
Parameters are as follows: 1, cylinder diameter, inner diameter size; 2, import and export diameter and thread parameters; 3, piston rod diameter; 4, cylinder pressure, cylinder working pressure, calculation is often used test pressure, less than 16MPa multiplied by 1.5, higher than 16MPa multiplied by 1.25. 5, cylinder stroke; 6. Is there a buffer? According to the working conditions, the piston rod extension contraction is generally buffered if the impact is large. 7, the installation of the cylinder.
