(Australia roller press hydraulic cylinder,produced by Hebei Hengyu company）

roller press hydraulic cylinder are widely used in Australia，because of powerful torque，simple structure and reliable operation，long service life.So our company has designed roller press hydraulic cylinder for customers from Australia.

Introduction to roller press hydraulic cylinder:

If the roller press hydraulic cylinder piston rod is found to be worn, it can be brushed and plated first, then ground, and finally adjust the mating accuracy of the piston rod and the guide sleeve. At this time, the guide sleeve can be properly redrilled or the guide sleeve can be re-turned. When making the above repairs, remember to replace various rubber seals in time.

When the roller press hydraulic cylinder is installed, the piston and the roller press hydraulic cylinder head and other parts have large mass, large size and large inertia, even if there is a lifting equipment auxiliary installation, because the specified clearance is small, no matter how hard it will be put into, therefore, the end of the piston or the roller press hydraulic cylinder head boss is easy to cause scars when it hits the inner surface of the roller press hydraulic cylinder wall. The solution to this problem: for a large number of small products, the use of autocratic assembly oriented tools during installation; For heavy, thick and large large and medium-sized roller press hydraulic cylinders, only careful and careful operation can be avoided.

Under normal circumstances, the roller press hydraulic cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the roller press hydraulic cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the roller press hydraulic cylinder and the end cover, the piston and the piston rod, the piston and the roller press hydraulic cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the roller press hydraulic cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.

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.

Answers to some questions about roller press hydraulic cylinder:

The hydraulic cylinder is slow when moving forward and faster when moving back.
If the cylinder is single, it is slow when it is moving forward without the rod cavity, and fast when it is shrinking.

How do hydraulic equipment and hydraulic cylinders maintain a certain pressure after pressing to a certain position?
There are several methods. 1. You can use a constant pressure variable pump to adjust the control pressure of the pump to the pressure required by the cylinder, so that when the cylinder is in place, the pump uses the minimum flow rate to maintain the pressure, and the system is more energy saving. 2. If the pressure is maintained for a short time, a hydraulic control check valve can be added to the oil inlet end of the cylinder to close the cylinder and maintain the pressure. If the volume of the cylinder is large, an accumulator can be added between the valve and the cylinder to maintain pressure for 10-30 minutes. 3. You can add a small flow pump, the large pump after unloading, the small pump has been running, specifically for maintaining pressure.
