(Luxembourg roller press hydraulic cylinder,produced by Hebei Hengyu company）
roller press hydraulic cylinder are widely used in Luxembourg，because of no transmission clearance，powerful torque，excellent temperature resistance.So our company has designed roller press hydraulic cylinder for customers from Luxembourg.
When the initial action of the roller press hydraulic cylinder is slow, please check the temperature of the hydraulic system, because in the case of low temperature, the viscosity of the hydraulic oil is large and the fluidity is poor, resulting in slow action of the roller press hydraulic cylinder. The improvement method is to replace the hydraulic oil with good viscosity temperature performance, and the oil temperature at low temperature can be increased by heater or heating by the machine itself, and the normal working oil temperature of the system should be maintained at about 40 ° C.
When producing oil roller press hydraulic cylinders, there are two processing processes, grinding and rolling, the latter is better than the former. Rolling machining is a kind of non-cutting machining, using the plastic deformation of the metal at room temperature, so that the micro roughness of the workpiece surface is flattened to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve the two purposes of finishing and strengthening at the same time, which can not be done by grinding.
If the piston rod and roller press hydraulic cylinder are stuck or the roller press hydraulic cylinder is blocked, at this time, no matter how to operate, the roller press hydraulic cylinder does not move or has little action. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the roller press hydraulic cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.
The definition of the minimum starting pressure of the roller press hydraulic cylinder refers to the minimum working pressure of the roller press hydraulic cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the roller press hydraulic cylinder parts and the size of the sealing friction.
What does cylinder speed ratio mean?
The speed ratio of the cylinder is the ratio of the reciprocating speed of the piston, equal to the ratio of the rodless cavity area to the roded cavity area.
How to control the speed of the cylinder?
High demand control, it is necessary to use servo closed-loop control, you can adjust the speed at will. Reference: Hydrodynamic Motion Control Practical Design Guide.
