(Brazil tailplate hydraulic cylinder,produced by Hengyu Group）

tailplate hydraulic cylinder are widely used in Brazil，because of powerful torque，clever hydraulic energy conversion，no transmission clearance.So our company has designed tailplate hydraulic cylinder for customers from Brazil.

Introduction to tailplate hydraulic cylinder:

When the tailplate hydraulic cylinder is repaired, its inner and outer diameter and roundness should be accurately measured. If the inner hole of the tailplate hydraulic cylinder is badly worn, it can be repaired by grinding the mandrel or honing on the boring machine. If the piston is worn, it can be repaired by electroplating, and serious wear should be replaced.

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

The viscosity of the working oil used in the tailplate hydraulic cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.

When the tailplate hydraulic cylinder needs to be stored for a period of time, please follow the recommended methods: The tailplate hydraulic cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the tailplate hydraulic 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 tailplate hydraulic cylinder should not be in direct contact with water vapor for a long time. The tailplate hydraulic cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the tailplate hydraulic 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 tailplate hydraulic cylinder Before working, the tailplate hydraulic cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the tailplate hydraulic cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

Answers to some questions about tailplate hydraulic cylinder:

Is it good or bad for the hydraulic cylinder working in the limit stroke position?
It is not good for the hydraulic cylinder working in the limit stroke position. Generally, when the cylinder is used in the limit stroke, the oil in the cylinder will form a backflow back pressure impact on the piston and guide sleeve seals. If the limit is not accurate, it is easy to cause collision damage. It is recommended to leave a buffer of ten to twenty centimeters.

What are the cylinder manufacturing processes?
Hydraulic cylinder processing process: 1, cylinder: a, material preparation (seamless steel pipe) → inspection (material certificate, etc.) → tempering (outsourcing: Some parts) → car (car round, shelf mouth, boring, flange stop, etc.) → tempered hardness test → welding (welded pipe joint base, flange and other accessories) → boring or honing (rough boring, fine boring, rolling) → car (hole slot or internal and external thread) → fitter (drilling) → inspection → rust prevention storage b, material preparation (forgings) → inspection (material certificate, inspection, etc.) → welding (blank butt welding) → welding inspection → car (rough car) → quality control (outsourcing: some parts) → car (car round, shelf mouth, boring stop, flange stop, etc.)
