(Portugal reset cylinder,produced by Hengyu Hydraulic Co., Ltd）

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

Introduction to reset cylinder:

When the reset cylinder needs to be stored for a period of time, please follow the recommended methods: The reset cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the reset cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil reset cylinder should not be in direct contact with water vapor for a long time. The reset cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the reset cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the reset cylinder Before working, the reset cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the reset cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

In recent years, the processing process of the reset cylinder generally adopts the rolling method, which is a pressure finishing processing, which uses the cold plastic characteristics of the metal at room temperature, and uses the rolling tool to exert a certain pressure on the surface of the workpiece, so that the surface metal of the workpiece produces plastic flow, and fills in the low concave trough of the original residue, and the roughness value of the workpiece surface is reduced. Due to the plastic deformation of the rolled surface metal, the surface tissue is cold hardened and the grain is fine, forming a dense fiber, and forming a residual stress layer, and the hardness and strength are increased, thus improving the wear resistance, corrosion resistance and compatibility of the workpiece surface. Rolling is a plastic machining method without cutting.

If the piston rod and reset cylinder are stuck or the reset cylinder is blocked, at this time, no matter how to operate, the reset 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 reset cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

reset cylinder and hydraulic station selection: Select the type and structure of the reset cylinder according to the operation requirements of the main engine. According to the external load force borne by the reset cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the reset 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 reset cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the reset cylinder, the diameter of the piston and the piston rod.

Answers to some questions about reset cylinder:

What material should be selected to seal the cylinder?
The choice of material for sealing is related to the working environment, strength, and medium of your equipment.

What is the valve on the hydraulic cylinder?
Oil valve, relief valve, overload valve, explosion-proof valve, etc., these are very convenient to insert! The oil valve, the overload valve and the blasting valve are very important for larger cylinders. Manufacturers will not offer you the selection. You need to choose the values by yourself according to your system, pump, cylinder, environment, working conditions and other comprehensive consideration!
