(Argentina hinge shaft cylinder,produced by Hengyu Group）

hinge shaft cylinder are widely used in Argentina，because of excellent fatigue and impact resistance，smooth movement，high work efficiency.So our company has designed hinge shaft cylinder for customers from Argentina.

Introduction to hinge shaft cylinder:

After chrome plating of the piston rod of the hinge shaft cylinder, the surface flatness is not fully treated: After chrome plating of the piston rod surface, the method of post-plating polishing should be changed to post-plating polishing. Although it is necessary to increase the thickness of the coating before grinding (generally increased by about 0.02 in the diameter direction), it can remove chrome plating defects well, and test the binding force of the coating. In addition, due to the micro-roughness of the grinding surface, the trough can store lubricating oil, which can improve the wear resistance and extend the service life.

When the long-stroke hinge shaft cylinder rotates horizontally, the piston rod bends due to its own weight, causing the guide sleeve and piston to produce biased load, resulting in hinge shaft cylinder head seal damage, oil leakage, and piston sleep in the hinge shaft cylinder. The following measures can be taken: increase the piston plan to adjust the piston outer circle and process it into a convex drum, so that the piston can self-position, improve the force situation, and reduce and avoid pulling the hinge shaft cylinder; The piston and the piston rod are connected with a spherical joint.

hinge shaft cylinder and hydraulic station selection: Select the type and structure of the hinge shaft cylinder according to the operation requirements of the main engine. According to the external load force borne by the hinge shaft cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the hinge shaft cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the hinge shaft cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the hinge shaft cylinder, the diameter of the piston and the piston rod.

When installing the piston rod, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the hinge shaft cylinder head adn the earring (or the middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent the phenomenon of rigid interference and causing unnecessary damage.

Answers to some questions about hinge shaft cylinder:

Is it good or bad for the hydraulic cylinder working in the limit stroke position?
It is not good for the hydraulic cylinder working in the limit stroke position. Generally, when the cylinder is used in the limit stroke, the oil in the cylinder will form a backflow back pressure impact on the piston and guide sleeve seals. If the limit is not accurate, it is easy to cause collision damage. It is recommended to leave a buffer of ten to twenty centimeters.

How to disassemble the big nut that excavate the oil cylinder piston of the excavator?
If you want to be safe, look for a special unloading place for this thing, which is an oil cylinder on top of a turntable with a large nut attached to the center of the turntable. If you're in the field just pin the head of the cylinder to one end, use a big homemade wrench to hold the nut in place, and then get a digging machine and push it down, and it opens.
