(Colombia flanged hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）
flanged hydraulic cylinder are widely used in Colombia，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed flanged hydraulic cylinder for customers from Colombia.
flanged hydraulic cylinder installation precautions: Before installing the flanged hydraulic cylinder into the system, the parameters on the flanged hydraulic cylinder label should be compared with the parameters when ordering. The base of the flanged hydraulic cylinder must have sufficient stiffness, otherwise the flanged hydraulic cylinder will bend upward into a bow when pressurized, so that the piston rod will bend.
The quality of the flanged hydraulic cylinder can not be ignored in the purchase of the flanged hydraulic cylinder. The flanged hydraulic cylinder is the main component of the flanged hydraulic cylinder, the single pillar for mining, the hydraulic support, the gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. flanged hydraulic cylinder processing requirements are high, its internal surface roughness requirements are Ra0.4 ~ 0.8μm, the coaxiality, wear resistance requirements are strict. The basic feature of flanged hydraulic cylinder is deep hole processing, which has always troubled the processing personnel.
Under normal circumstances, the flanged hydraulic cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the flanged hydraulic cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the flanged hydraulic cylinder and the end cover, the piston and the piston rod, the piston and the flanged hydraulic cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the flanged hydraulic cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.
The coordination of the sliding parts of the flanged hydraulic cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.
About the hydraulic cylinder wall thickness problem?
Hydraulic cylinder wall thickness calculation formula: t=PD/200St= pipe wall thickness (minimum thickness) mmP= maximum pressure kg/cm2? d= inner diameter mm? S=δ/5 safety factor δ= minimum tensile strength This case: set the cylinder material 45#, tensile strength 58kg/cm2t=(640X40)/(200X11.6)t=11mm piston output (i.e. Thrust) calculation formula: F1=PD2X(3.14/4)F1=640X42X0.785=8,038kg Note: Square numbers will not be used, all 2's in the text are square codes.
How to calculate hydraulic cylinder flow?
Effective area of the cylinder x stroke = volume usually in liters. Volume/estimated total travel time (converted to minutes) = oil flow rate.
