Morocco hydraulic cylinder,unidirectional cylinder manufacturer,unidirectional cylinder

(Morocco unidirectional cylinder,produced by Hebei Hengyu company）

unidirectional cylinder are widely used in Morocco，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed unidirectional cylinder for customers from Morocco.

Introduction to unidirectional cylinder:

The unidirectional cylinder should be avoided for a long time without use, if it is indeed idle for a long time for some reason, it should also be regularly turned on for empty operation, so that its parts can be fully lubricated, so as to avoid rust on the working surface and affect the normal work in the future. (If it cannot be turned on and run, a small amount of lubricating oil can be applied on its outer surface for protection) ' The use of the unidirectional cylinder should pay attention to: the operation should be as far away from the unidirectional cylinder as possible, to avoid falling objects, knocking, rubbing the unidirectional cylinder coating. When cleaning the unidirectional cylinder, only use soft materials (such as cotton) to wipe, and do not scratch high-hardness materials. Do not use the unidirectional cylinder when the oil temperature exceeds 70 ° C.

The viscosity of the working oil used in the unidirectional 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 material, shape and compression of the unidirectional cylinder seal have a great impact on the service life and work efficiency of the unidirectional cylinder. In addition to requiring a reliable seal, it should also have a long service life and less friction loss. At present, there are many seal manufacturers in the country, and it is also crucial to choose high-quality seals with reliable and stable quality.

Regular maintenance of the unidirectional cylinder includes: regular tightening, unidirectional cylinder fastening screws and gland screws, unidirectional cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the unidirectional cylinder once a year. Clean regularly, the unidirectional cylinder is cleaned every other year, and the seals are replaced while cleaning.

Answers to some questions about unidirectional cylinder:

How to determine the rated working pressure of the hydraulic cylinder?
Under normal circumstances, the working pressure is determined according to the size of the load and the installation space (the allowable diameter of the cylinder). In some special occasions, the smaller the cylinder, the better, the pressure level must be increased. The cylinder pressure is related to the estimated cost. The higher the pressure, the thicker the wall, the higher the cost, but conversely, the lower the pressure, the larger the diameter of the cylinder (when the same thrust) is required, the same high cost. Therefore, the rated pressure of the cylinder is concentrated in about 35 mpa, taking into account the cylinder diameter and wall thickness.

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.)
