(Greece hydraulic punch cylinder,produced by Hengyu Group）

hydraulic punch cylinder are widely used in Greece，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed hydraulic punch cylinder for customers from Greece.

Introduction to hydraulic punch cylinder:

Do not regularly check the damage of the chrome layer of the hydraulic punch cylinder: completely extend the hydraulic punch cylinder and carefully check whether there is any surface damage such as injury, strain, welding slag, such as the surface damage position, in the hydraulic punch cylinder block < 20cm, and the damage depth < 5mm, should be repaired in time to prevent long-term damage to the hydraulic punch cylinder seal. Welding slag is strictly prohibited on the surface of the hydraulic punch cylinder.

The hydraulic punch cylinder should be avoided for a long time without use, if it is indeed idle for a long time for some reason, it should also be regularly turned on for empty operation, so that its parts can be fully lubricated, so as to avoid rust on the working surface and affect the normal work in the future. (If it cannot be turned on and run, a small amount of lubricating oil can be applied on its outer surface for protection) ' The use of the hydraulic punch cylinder should pay attention to: the operation should be as far away from the hydraulic punch cylinder as possible, to avoid falling objects, knocking, rubbing the hydraulic punch cylinder coating. When cleaning the hydraulic punch cylinder, only use soft materials (such as cotton) to wipe, and do not scratch high-hardness materials. Do not use the hydraulic punch cylinder when the oil temperature exceeds 70 ° C.

The hydraulic punch cylinder should not be mixed with foreign objects during assembly, which will cause scars. Before the total assembly of the hydraulic punch cylinder, all parts must be fully removed and cleaned. When the parts are installed with burrs or dirt, foreign objects are easily embedded into the surface of the hydraulic punch cylinder wall due to the stiffness and the weight of the parts, causing scars.

The cavitation of the hydraulic punch 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 hydraulic punch 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.

Answers to some questions about hydraulic punch cylinder:

Why does excavator cylinder oil leak?
Under normal circumstances, the leakage of hydraulic cylinders is divided into internal leakage and external leakage. The external leakage is generally due to damage to the oil seal at the extended end of the piston rod and needs to be replaced. Internal leakage is generally because the oil seal on the piston is damaged, you can try to replace the oil seal here, if the replacement will also leak, then check whether there is damage to the inner wall of the cylinder.

Is there a way to make the cylinder stop pushing when it hits something hard during the process of pushing?
The simplest solution is to press the stop switch, this switch has a mechanical type, touch the object on the action or send a stop signal, through the operation of the motor control cylinder; There is also an induction switch, that is, when the hydraulic cylinder expands to the range of the induction switch can sense the signal, it sends a signal to let the motor act, resulting in the corresponding action of the cylinder.
