(Croatia roller press hydraulic cylinder,produced by Hebei Hengyu company）
roller press hydraulic cylinder are widely used in Croatia，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed roller press hydraulic cylinder for customers from Croatia.
How to repair the roller press hydraulic cylinder body when it is damaged: When the roller press hydraulic cylinder has trace deformation and shallow tensile marks, the roller press hydraulic cylinder is repaired by strong honing process. The heavy honing process can repair roller press hydraulic cylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the roller press hydraulic cylinder can meet the technical requirements.
The internal leakage of the roller press hydraulic cylinder is an important indicator to measure the quality of the roller press hydraulic cylinder: the internal leakage of the roller press hydraulic cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the roller press hydraulic cylinder, so that the roller press hydraulic cylinder can not accurately and stably stop in a certain position of the roller press hydraulic cylinder, so it is one of the main indicators of the roller press hydraulic cylinder.
The repair method of the roller press hydraulic cylinder: the repair of the roller press hydraulic cylinder must use brush plating. This is because this repair method can be carried out on site, and the repair effect is good. In this way, loading and transportation can be eliminated to shorten the repair time and improve work efficiency. In addition, the coating obtained by brush plating has good binding force and will not have obvious boundaries. Moreover, the repair surface has high hardness and good wear resistance.
roller press hydraulic cylinder abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the roller press hydraulic cylinder is placed for a period of time, the roller press hydraulic 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.
How to deal with oil cylinder leakage?
The causes of oil leakage and treatment methods are as follows: (1) The spool is stuck or the valve hole is blocked. When the spool of the flow valve or direction valve is stuck or the valve hole is blocked, the hydraulic cylinder is prone to misoperation or operation failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check valve body for wear. (2) The piston rod and cylinder are stuck or the hydraulic cylinder is blocked. At this time, no matter how to operate, the hydraulic cylinder does not move or moves very little. At this time, it should be checked whether the piston and piston rod seal is too tight, whether it enters the dirt and colloid precipitate: whether the shaft line of the piston rod and the cylinder is in alignment, and whether the wearing parts and seals are invalid.
What size of hydraulic cylinder is needed for 200 tons pressure? The pressure of the cylinder at work is determined by the load, and the pressure of the physical force is equal to the force divided by the area of action (that is, P=F/S). If you want to calculate the output force of the cylinder, you can calculate by the formula: Set the radius of the piston (that is, the cylinder) is R (unit mm) the radius of the piston rod is r (unit mm) the pressure level P (unit MPa) when working, then the thrust of the cylinder F push =3.14*R*R*P (unit N) the pull of the cylinder F pull =3.14* (R* R-R *R) *P (unit N) 100 tons of the cylinder, System pressure 16Mpa.
