(Burma swager cylinder,produced by Hengyu Hydraulic Cylinder Factory）
swager cylinder are widely used in Burma，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed swager cylinder for customers from Burma.
swager cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the swager cylinder head itself is the guide sleeve of the piston rod, the swager cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the swager cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.
After the swager cylinder is installed, lubricating grease should be added to the relative moving parts such as earring and middle hinge shaft before trial operation.
How to repair the swager cylinder body when it is damaged: When the swager cylinder has trace deformation and shallow tensile marks, the swager cylinder is repaired by strong honing process. The heavy honing process can repair swager cylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the swager cylinder can meet the technical requirements.
The internal leakage of the swager cylinder is an important indicator to measure the quality of the swager cylinder: the internal leakage of the swager cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the swager cylinder, so that the swager cylinder can not accurately and stably stop in a certain position of the swager cylinder, so it is one of the main indicators of the swager cylinder.
Cylinder pressure calculation formula
The pressure of the cylinder at work is determined by the load, and the pressure of the physical force is equal to the force divided by the area of action (that is, P=F/S). If you want to calculate the output force of the cylinder, you can calculate it according to the formula: Set the radius of the piston (that is, the cylinder) is R (unit mm) the radius of the piston rod is r (unit mm) the working pressure P (unit MPa) the thrust of the cylinder F push =3.14*R*R*P (unit N) The pulling force of the cylinder F pull =3.14* (R*R-r* R) *P (unit N).
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.
