(El Salvador retractable cylinder,produced by Hengyu Group）

retractable cylinder are widely used in El Salvador，because of simple structure and reliable operation，powerful torque，clever hydraulic energy conversion.So our company has designed retractable cylinder for customers from El Salvador.

Introduction to retractable cylinder:

When the retractable cylinder is repaired, its inner and outer diameter and roundness should be accurately measured. If the inner hole of the retractable 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 viscosity of the working oil used in the retractable 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.

The daily inspection of the retractable cylinder includes: checking the connection of the retractable cylinder and the pipe joint for leaks. Check the retractable cylinder rod for leaks. Check the retractable cylinder connection for leaks. When the retractable cylinder moves, the work is normal and smooth. Whether the retractable cylinder has internal leakage.

Do not regularly check the damage of the chrome layer of the retractable cylinder: completely extend the retractable cylinder and carefully check whether there is any surface damage such as injury, strain, welding slag, such as the surface damage position, in the retractable cylinder block < 20cm, and the damage depth < 5mm, should be repaired in time to prevent long-term damage to the retractable cylinder seal. Welding slag is strictly prohibited on the surface of the retractable cylinder.

Answers to some questions about retractable cylinder:

The diameter of the cylinder is 180mm and the pressure is 14mpa. How many tons can the cylinder hold?
Calculate the area of the cylinder, 3.14*9*9=254.34 square centimeters, take the approximate number of engineering, 1 mpa pressure is about 10 kg per square centimeter, 14 mpa pressure is 140 kg per square centimeter, that is 254.34*140=35607.6 kilograms, it can be known that the cylinder can be about 35 tons in theory.

How to distinguish the size of hydraulic cylinder cavity?
The hydraulic cylinder has a rod cavity and a rodless cavity. The rod cavity is the cavity that the piston rod extends out. The rod cavity is of course small due to the existence of the piston rod. That's just relative.
