Libya hydraulic cylinder,stroke adjustable cylinder manufacturer,stroke adjustable cylinder

(Libya stroke adjustable cylinder,produced by Hengyu Hydraulic Cylinder Factory）

stroke adjustable cylinder are widely used in Libya，because of no need for deceleration device，long service life，smooth movement.So our company has designed stroke adjustable cylinder for customers from Libya.

Introduction to stroke adjustable cylinder:

stroke adjustable cylinders in series, parallel and series parallel. Series: In the stroke adjustable cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Series: In the stroke adjustable cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Parallel: the pressure oil in the stroke adjustable cylinder is connected with the inlet oil of each reversing valve, and the return oil is collected by the return oil circuit. Series parallel: For this one, compared with the simple series and parallel, it is slightly more complicated, but it is not impossible to understand. The series refers to the oil in the stroke adjustable cylinder, which is in series form, but can not form a series circuit, and the parallel refers to the oil return circuit of each valve, which is in parallel.

When installing the stroke adjustable cylinder pipe, the pipe should be cleaned after installation, and should not pass through the stroke adjustable cylinder block, and the by-pass pipe must be installed in front of the oil port of the stroke adjustable cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the stroke adjustable cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the stroke adjustable cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.

The stroke adjustable cylinder is not the same as the stroke adjustable cylinder, because the pressure of the pneumatic system is generally within the range of 0.2-1.0Mpa, the stroke adjustable cylinder can not be used as a high-power power component, but the stroke adjustable cylinder can be used as a relatively large power component, or the stroke adjustable cylinder system can be used.

When the stroke adjustable cylinder is customized, if there are high requirements for the quality of the stroke adjustable cylinder, it is best to use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface of the small crack, preventing the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the stroke adjustable cylinder can be improved. By rolling forming, a cold working hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving the wear resistance of the inner wall of the stroke adjustable cylinder and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the matching property.

Answers to some questions about stroke adjustable cylinder:

What does the maximum output force of the cylinder piston mean?
The maximum output of the cylinder is related to the pressure of the hydraulic system that you link to the cylinder. For example, the rated maximum output thrust of the MOB 50 cylinder is 1.3 tons and the rated pressure is 7Mpa. That is, when the input hydraulic oil pressure of the cylinder reaches 7Mpa, the maximum output thrust of the cylinder is only 0.98 tons. When the input hydraulic pressure is only 5Mpa, the maximum output thrust of the cylinder is 1.3 tons. Because the pressure of the cylinder limit is only 7Mpa, if the oil pressure of the input system exceeds 7Mpa, the cylinder can not withstand the pressure burst, and it is damaged.

What is the material of the hydraulic cylinder slider?
Three parts of the hydraulic cylinder are essential, which are: cylinder - cylinder head assembly, piston - piston rod assembly, and sealing device. When you say slider, you mean piston. - Piston rod. Piston materials commonly used gray cast iron, wear-resistant cast iron, aluminum alloy (assembled), etc., can also be used 35 and 45 steel (integral). The piston rod is generally made of 35 and 45 steel. When the impact vibration is large, alloy steel such as 55 steel or 40Cr is used.
