(Algeria shearing machine cylinder,produced by Hebei Hengyu company）

shearing machine cylinder are widely used in Algeria，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed shearing machine cylinder for customers from Algeria.

Introduction to shearing machine cylinder:

shearing machine cylinder abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the shearing machine cylinder is placed for a period of time, the shearing machine cylinder may enter the air, and the movement can be normal after dozens of repeated movements. If it still cannot be eliminated, check whether the load is aligned with the axis of the piston rod; Retracted piston rod installation helps to align the load with the piston rod. If the flow is unstable, it will also lead to abnormal movement of the piston rod. Check the relevant components of the hydraulic system.

In order to ensure the service life of the shearing machine cylinder, the medium used must not be mixed with impurities and stolen goods, so as to avoid scratching the inner arm of the shearing machine cylinder, causing damage to the seal and causing leakage in the shearing machine cylinder. It is required that the filtration accuracy of the system is not less than 80μm, the oil pollution is strictly controlled, the hydraulic oil is kept clean, the performance of the hydraulic oil is regularly checked, and the necessary fine filtration or replacement of the new working hydraulic oil is carried out.

The piston rod and guide sleeve function of the shearing machine cylinder is crucial: the relative motion pair between the piston rod and the guide sleeve is the main factor causing external leakage, if the chrome layer on the surface of the piston rod is spalling or producing longitudinal tensile marks due to wear, it will directly lead to the failure of the seal.

Factors that should be considered when selecting the oil seal in the shearing machine cylinder: some specific factors should be taken into account when selecting the oil seal in the shearing machine cylinder, so as to have correct consideration and get accurate results, and then avoid wrong selection. The factors and aspects that should be taken into account are eight: shearing machine cylinder diameter, piston rod diameter, piston rod and piston groove size, shearing machine cylinder working pressure, shearing machine cylinder movement speed, hydraulic system oil temperature and shearing machine cylinder working environment.

Answers to some questions about shearing machine cylinder:

Design a hydraulic cylinder, the inner diameter of the cylinder is 100mm, what size of piston rod is best used?
This involves how much speed ratio you need, that is, the area ratio of the rod cavity and the rodless cavity, if the weight is relatively large, it is recommended that the speed ratio choose 2, that is, the piston rod diameter choose 70mm, under normal circumstances, the speed ratio choose 1.46, the piston rod diameter choose 55mm. Of course, there are many factors that affect the diameter of the piston rod, such as stroke, stroke is too long, in order to stabilize the work of the hydraulic cylinder, its diameter also needs to choose a relatively large, sometimes even non-standard products, need to choose according to the actual situation.

100 tons press, the cylinder diameter is 250, how much pressure?
100 tons hydraulic press, if it is a single acting hydraulic cylinder, the required oil pressure is the nominal force divided by the cross-sectional area of the cylinder piston. One hundred tons of its pressure is 1000 kN (1000000N), the diameter of the cylinder is 250 mm, its area is the circular rate multiplied by the square of the radius, is 49062.5 square mm, and then the pressure divided by the area of the oil pressure is 20.38MPa. Therefore, a hydraulic pressure of 20.38 mpa is required for a 250 diameter cylinder to obtain 100 tons of pressure.
