(Czech Republic stroke adjustable cylinder,produced by Hengyu Hydraulic Cylinder Factory）
stroke adjustable cylinder are widely used in Czech Republic，because of powerful torque，long service life，smooth movement.So our company has designed stroke adjustable cylinder for customers from Czech Republic.
The advantages and disadvantages of the stroke adjustable cylinder: the surface of the stroke adjustable cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the stroke adjustable cylinder through the top heat treatment, high manufacturing precision, belongs to the precision machinery, has a simple structure, stable quality, high mechanical efficiency, easy to achieve automation and many other advantages. However, hydraulic technology also has the shortcomings of oil leakage, oil temperature change affecting the control of running speed, noise, expensive cost and high maintenance cost.
The difference between the plunger stroke adjustable cylinder and the piston stroke adjustable cylinder is that the piston in the stroke adjustable cylinder is replaced by a shaft plunger, which is used in hydraulic transmission requiring a long mechanical stroke, and can only input pressure oil from one direction, pressurize in a single direction, and form a thrust to push the plunger to move. The return trip of the plunger depends on the plunger itself to fall, and some rely on the spring to push back to the original position. Usually used plunger type stroke adjustable cylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.
The stroke adjustable 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 stroke adjustable cylinder should pay attention to: the operation should be as far away from the stroke adjustable cylinder as possible, to avoid falling objects, knocking, rubbing the stroke adjustable cylinder coating. When cleaning the stroke adjustable cylinder, only use soft materials (such as cotton) to wipe, and do not scratch high-hardness materials. Do not use the stroke adjustable cylinder when the oil temperature exceeds 70 ° C.
Protection of the stroke adjustable cylinder surface: During the dismantling process, safety protection should be carried out on the stroke adjustable cylinder to prevent objects from falling and welding slag from falling to the surface, causing damage to the stroke adjustable cylinder surface. In the process of propulsion, the damaged pipe segments should be prevented from falling and smashing, and the slurry remaining on the surface of the stroke adjustable cylinder should be cleaned up in time.
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.
What is the pressure provided for a 63-bore cylinder with a pressure of 2 mpa?
2 mpa pressure is equivalent to 20 kg per square centimeter, 6.3 cm straight longitude, 3.15 cm radius, square, multiplied by, calculated an area of about 31.5 square centimeters, multiplied by 20 kg, the pressure is about 630 kg.
