Costa Rica hydraulic cylinder,loading cylinder manufacturer,loading cylinder(Costa Rica loading cylinder,produced by Hengyu Hydraulic Co., Ltd)
loading cylinder are widely used in Costa Rica,because of excellent fatigue and impact resistance,high work efficiency,no need for deceleration device.So our company has designed loading cylinder for customers from Costa Rica.
When the loading cylinder is customized, if there are high requirements for the quality of the loading 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 loading 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 loading cylinder and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the matching property.
When the loading cylinder wear is serious, you can try to use an alloy scraper to shave grooves with a depth of more than 1mm on the surface of the slip injury, then clean the grooves with acetone, apply the adjusted TS311 anti-wear repair agent on the polished surface with the loading cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the loading cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the loading cylinder can meet the requirements by grinding. However, the life and reliability of this repair loading cylinder are not high.
Analysis of commonly used seals: The wear ring and slip ring commonly used on the loading 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%.
The loading cylinder can not be used as grounding electrode to avoid electric damage to the piston rod.
How to disassemble injection molding machine injection cylinder?
If it is not repaired for a long time, it is recommended to open both ends, comprehensively check the oil seal and piston ring inside, this is not much difficulty, pay attention to not install reverse when changing the oil seal, some piston rings are steel rings are rubber rings, and several interfaces of steel rings are not in the same position; Rubber ring pay attention not to install reverse; Be careful not to damage the oil seal when installing, otherwise it will soon leak oil.
What are the standard cylinder models for hydraulic cylinders?
National standard GB/T2348-1993 specifies the hydraulic cylinder inner diameter series, you can check GB/T2348-1993 relevant regulations.
