Indonesia hydraulic cylinder,servo cylinder manufacturer,servo cylinder(Indonesia servo cylinder,produced by Hebei Hengyu company)
servo cylinder are widely used in Indonesia,because of excellent temperature resistance,no transmission clearance,powerful torque.So our company has designed servo cylinder for customers from Indonesia.
When installing the servo cylinder pipe, the pipe should be cleaned after installation, and should not pass through the servo cylinder block, and the by-pass pipe must be installed in front of the oil port of the servo cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the servo cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the servo cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.
The cavitation of the servo cylinder has a great influence, and to avoid it, it is necessary to use the hydraulic oil reasonably and ensure the quality of the hydraulic oil. If the anti-foam property of the oil is poor, it is easy to produce foam, resulting in cavitation. Secondly, the change frequency of oil pressure is too fast and too high, which will also directly cause the formation of bubbles and accelerate the rupture rate of bubbles. The test shows that the speed of cavitation will be accelerated in the part with high frequency of pressure change. For example, at the inlet and outlet of the servo cylinder, due to the relatively high frequency of pressure changes, the degree of cavitation is also relatively higher than that of other parts. In addition, overheating of the oil will also increase the probability of cavitation.
If the servo cylinder slips or crawls, please check whether there is astringency inside the servo cylinder, because the internal parts of the servo cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, the action resistance is too large, so that the piston speed of the servo cylinder changes with the different stroke position, and the slip or crawl occurs. Most of the reasons are due to poor assembly quality of parts, surface scars or sintered iron filings, so that the resistance increases, the speed decreases. For example, the piston is different from the piston rod or the piston rod is bent, the servo cylinder or the piston rod is offset from the mounting position of the guide rail, and the sealing ring is too tight or too loose. The solution is to repair or adjust, replace damaged parts and remove iron filings.
The servo cylinder should be used as far as possible to avoid the transverse force, sometimes the piston rod to bear the transverse load is too large, especially do not force or pull the servo cylinder, bite. Elimination method: When installing the servo cylinder, ensure that the axis position of the servo cylinder is consistent with the direction of movement; Make the load borne by the servo cylinder as far as possible through the servo cylinder axis, to avoid the phenomenon of eccentricity.
How to remove the cylinder correctly?
(1) Before disassembling the hydraulic cylinder, the hydraulic circuit should be depressurized. Otherwise, when the tubing joint connected with the cylinder is loosened, the high-pressure oil in the circuit will be quickly ejected. The hydraulic circuit of the hydraulic press should first loosen the hand wheel or pressure regulator screw at the relief valve, so that the pressure oil is unloaded, and then block the power supply or block the power source to stop the operation of the hydraulic equipment. (2) When disassembling, it should prevent damage to the top thread of the piston rod, the oil thread, the appearance of the piston rod, the inner wall of the cylinder liner, etc. In order to prevent the piston rod and other slender parts from twisting or deformation, the use of cushion wood support balance when placed. (3) Disassemble in order.
What is the smallest cylinder size?
The smallest shape cylinder I have ever seen is a hydraulic clamping cylinder in the machine tool industry. Outer diameter 24 mm, total length 23 mm, travel 4 mm. Weighs 0.05 kg. Maximum clamping force 3500 Newtons.
