(Slovakia synchronous hydraulic cylinder,produced by Hebei Hengyu company）

synchronous hydraulic cylinder are widely used in Slovakia，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed synchronous hydraulic cylinder for customers from Slovakia.

Introduction to synchronous hydraulic cylinder:

Improve the service life of the synchronous hydraulic cylinder: it is necessary to maintain the normal clearance of the combined surface of the hydraulic components. When manufacturing or repairing the main parts of the synchronous hydraulic cylinder (such as the synchronous hydraulic cylinder block, piston rod, etc.), the assembly should be carried out in accordance with the tolerance lower limit of the assembly size, which can well reduce the occurrence of cavitation. If cavitation has occurred in the hydraulic components, only metallographic sandpaper polishing technology can be used to remove cavitation pitting and surface carbon deposits, and general fine sandpaper must not be used for polishing After the synchronous hydraulic cylinder is repaired, the hydraulic system should run smoothly for a certain period of time so that the hydraulic oil in the hydraulic system can be fully circulated; If necessary, the synchronous hydraulic cylinder inlet pipe (or return pipe) can be disassembled. Make the hydraulic oil overflow to achieve the effect of single synchronous hydraulic cylinder exhaust.

The difference between the plunger synchronous hydraulic cylinder and the piston synchronous hydraulic cylinder is that the piston in the synchronous hydraulic cylinder is replaced by a shaft plunger, which is used in hydraulic transmission requiring a long mechanical stroke, and can only input pressure oil from one direction, pressurize in a single direction, and form a thrust to push the plunger to move. The return trip of the plunger depends on the plunger itself to fall, and some rely on the spring to push back to the original position. Usually used plunger type synchronous hydraulic cylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.

When installing the synchronous hydraulic cylinder, the axial ends of the synchronous hydraulic cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the synchronous hydraulic cylinder, there is axial expansion. If the two ends of the synchronous hydraulic cylinder are fixed, all parts of the synchronous hydraulic cylinder will be deformed. When disassembling the synchronous hydraulic cylinder, it is strictly forbidden to hammer the synchronous hydraulic cylinder and the piston surface, such as the synchronous hydraulic cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.

How the cavitation of the synchronous hydraulic cylinder is formed: With the gradual rise of pressure, the gas in the oil will become bubbles, when the pressure rises to a certain limit value, these bubbles will break under the action of high pressure, so that the high temperature and high pressure gas will quickly act on the surface of the parts, resulting in cavitation of the synchronous hydraulic cylinder, resulting in corrosive damage to the parts.

Answers to some questions about synchronous hydraulic cylinder:

How many tons can a 10mpa cylinder with a diameter of 100 hold up?
About 8 tons. Algorithm: Cylinder cross-sectional area = π* (100/2) ^2=3.14*2500=7850 square mm = 0.00785 square meters pressure = pressure * Cross-sectional area = 10000000Pa*0.00785 square meters = 78500 n mass = pressure /g = 78500 N ÷9.8 n/kg = 8010 kg = 8.01 Tons.

Structural characteristics of the plunger cylinder? (1) The plunger hydraulic cylinder is a single-acting hydraulic cylinder, which can only move in one direction by hydraulic pressure, and the return trip of the plunger depends on other external forces or the weight of the plunger; (2) The plunger is only supported by the cylinder liner and is not in contact with the cylinder liner, so the cylinder liner is easy to process, so it is suitable for long stroke hydraulic cylinder; (3) the total pressure of the plunger during work, so it must have sufficient stiffness; (4) The weight of the plunger is often large, and it is easy to sag due to its own weight when placed horizontally, resulting in wear of the seals and guide side, so its vertical use is more favorable.
