Portugal electric furnace hydraulic cylinder

(Portugal electric furnace hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)

electric furnace hydraulic cylinder are widely used in Portugal,because of no need for deceleration device,long service life,smooth movement.So our company has designed electric furnace hydraulic cylinder for customers from Portugal.

Introduction to electric furnace hydraulic cylinder:

electric furnace hydraulic cylinder diameter, rod diameter, stroke determination: Choose national standards or other standards electric furnace hydraulic cylinder, avoid the selection of non-standard size, otherwise the difficulty of processing and manufacturing costs will be increased. The length of the electric furnace hydraulic cylinder guide is determined by the length of the stroke. Check the strength of electric furnace hydraulic cylinder, piston rod, screw, etc. according to the working pressure or load. At the same time, working pressure, ambient temperature, working medium and running speed are also the key to selecting seals.

If the seal of the electric furnace hydraulic cylinder is abnormal wear, you can check whether the speed control valve is improperly adjusted, resulting in too high back pressure and improper installation of the seal or hydraulic oil contamination. The second is whether there is a foreign body entering the assembly and the quality of the sealing material is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and electric furnace hydraulic cylinder, and the phenomenon of "pulling the electric furnace hydraulic cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operation and improvement should be done according to the installation instructions.

Improve the service life of the electric furnace hydraulic 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 electric furnace hydraulic cylinder (such as the electric furnace hydraulic 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 electric furnace hydraulic 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 electric furnace hydraulic cylinder inlet pipe (or return pipe) can be disassembled. Make the hydraulic oil overflow to achieve the effect of single electric furnace hydraulic cylinder exhaust.

Analysis of commonly used seals: The wear ring and slip ring commonly used on the electric furnace hydraulic cylinder are generally made of polytetrafluoroethylene + graphite, because pure polytetrafluoroethylene is easy to produce plastic creep, which is only suitable for low pressure and low wear resistance conditions. If the sealing ring used is a composite material formed after adding graphite filler, the performance can be effectively improved, the ability to resist plastic creep is increased by 2 to 3 times, the initial deformation caused by the load is reduced by 30 to 60% : the rigidity is increased by 2 to 3 times: the dimensional stability under heat is increased by 2 times, and the hardness is increased by l0 to 15%.

Answers to some questions about electric furnace hydraulic cylinder:

Why can't the hydraulic cylinder be pulled back after pushing to the limit?
May be long-term use to the limit position, resulting in serious wear caused! The solution is to add the stroke switch or disassemble and add gaskets before and after the piston.

Why are two cylinders not balanced with the balance valve?
Balancing valve is only suitable for occasions with low synchronous accuracy requirements, and proportional valves are recommended for occasions with high precision requirements.
