roller press hydraulic cylinder are widely used in UAE，because of excellent fatigue and impact resistance，smooth movement，high work efficiency.So our company has designed roller press hydraulic cylinder for customers from UAE.

Introduction to roller press hydraulic cylinder:

The assembly work of the roller press hydraulic cylinder has a great impact on the quality of the roller press hydraulic cylinder: each part must be carefully cleaned before assembly; To correctly install the sealing device everywhere: when installing the sealing ring, pay attention to its installation direction to avoid oil leakage due to installation, and its lip should be equipped with a pressure oil chamber. In addition, because it is a YX-shaped sealing ring, it is necessary to pay attention to distinguish between shaft and hole use, do not install wrong; Because the sealing device is matched with the sliding surface, an appropriate amount of hydraulic oil should be applied during assembly; The special wrench should be used when the threaded coupling is tightened, and the torque should meet the standard requirements; After the piston and piston rod are assembled, it is necessary to measure whether the coaxiality and straightness on the full length are out of whack. After assembly, there should be no blocking sensation and uneven resistance when the piston assembly moves.

The roller press hydraulic 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 roller press hydraulic cylinder, bite. Elimination method: When installing the roller press hydraulic cylinder, ensure that the axis position of the roller press hydraulic cylinder is consistent with the direction of movement; Make the load borne by the roller press hydraulic cylinder as far as possible through the roller press hydraulic cylinder axis, to avoid the phenomenon of eccentricity.

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.

When the roller press hydraulic cylinder needs to be disassembled for maintenance due to leakage and other faults, the piston should be moved to the bottom position of the roller press hydraulic cylinder, and hard beating and sudden drop are strictly prohibited during disassembly.

Answers to some questions about roller press hydraulic cylinder:

How to control the speed of the hydraulic cylinder?
The speed of the hydraulic cylinder is only related to the flow, so the control speed is to control the flow of the hydraulic oil, which is generally adjusted by the throttle valve in the system.

Why hydraulic cylinder load can not rise?
The hydraulic cylinder does not top up indicates that the pressure of the working chamber of the hydraulic cylinder is insufficient, and the following circumstances can lead to insufficient pressure: 1) The relief valve of the hydraulic system cannot establish pressure, elimination method: check whether the pressure setting screw of the relief valve is screwed to the appropriate position. If it is an electromagnetic relief valve, please check the power-on condition. 2) The hydraulic system pipeline is connected incorrectly, when P and T are connected, this must be checked and excluded; 3) Excessive leakage in the hydraulic cylinder, resulting in (only for double-acting cylinders); 3) No hydraulic oil into the working chamber of the hydraulic cylinder, elimination method: first disassemble the hydraulic pipe connecting the reversing valve and the hydraulic cylinder, and then control the reversing valve, and observe whether there is hydraulic oil flowing out of the reversing valve.
