Switzerland unidirectional cylinder

(Switzerland unidirectional cylinder,produced by Hebei Hengyu company)

unidirectional cylinder are widely used in Switzerland,because of clever hydraulic energy conversion,simple structure and reliable operation,excellent temperature resistance.So our company has designed unidirectional cylinder for customers from Switzerland.

Introduction to unidirectional cylinder:

Improve the service life of the unidirectional cylinder: it is necessary to maintain the normal clearance of the combined surface of the hydraulic components. When manufacturing or repairing the main parts of the unidirectional cylinder (such as the unidirectional cylinder block, piston rod, etc.), the assembly should be carried out in accordance with the tolerance lower limit of the assembly size, which can well reduce the occurrence of cavitation. If cavitation has occurred in the hydraulic components, only metallographic sandpaper polishing technology can be used to remove cavitation pitting and surface carbon deposits, and general fine sandpaper must not be used for polishing After the unidirectional cylinder is repaired, the hydraulic system should run smoothly for a certain period of time so that the hydraulic oil in the hydraulic system can be fully circulated; If necessary, the unidirectional cylinder inlet pipe (or return pipe) can be disassembled. Make the hydraulic oil overflow to achieve the effect of single unidirectional cylinder exhaust.

When the unidirectional cylinder is installed, the piston and the unidirectional 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 unidirectional cylinder head boss is easy to cause scars when it hits the inner surface of the unidirectional 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 unidirectional cylinders, only careful and careful operation can be avoided.

After chrome plating of the piston rod of the unidirectional cylinder, the surface flatness is not fully treated: After chrome plating of the piston rod surface, the method of post-plating polishing should be changed to post-plating polishing. Although it is necessary to increase the thickness of the coating before grinding (generally increased by about 0.02 in the diameter direction), it can remove chrome plating defects well, and test the binding force of the coating. In addition, due to the micro-roughness of the grinding surface, the trough can store lubricating oil, which can improve the wear resistance and extend the service life.

unidirectional cylinder and hydraulic station selection: Select the type and structure of the unidirectional cylinder according to the operation requirements of the main engine. According to the external load force borne by the unidirectional cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the unidirectional cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the unidirectional cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the unidirectional cylinder, the diameter of the piston and the piston rod.

Answers to some questions about unidirectional cylinder:

When the cylinder is tested, why can't the pressure be maintained with the balance valve?
Because the oil into the oil chamber through the hydraulic lock on the control oil circuit through the other side of the spool, the original valve is designed in this way. It locks the circuit after the oil supply circuit loses pressure, on the contrary, if you keep supplying pressure, it is always in the state of opening the other side of the one-way spool. So this valve can't be used in the test.

What diameter cylinder is needed for a force of 5 tons?
It depends on the pressure of your system pump. If the normal working pressure of the system is about 8MPa, then the diameter of the cylinder should be 100 mm.
