Hungary hydraulic cylinder,hydraulic lifting cylinder manufacturer,hydraulic lifting cylinder
(Hungary hydraulic lifting cylinder,produced by Hebei Hengyu company）
hydraulic lifting cylinder are widely used in Hungary，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed hydraulic lifting cylinder for customers from Hungary.
The coordination of the sliding parts of the hydraulic lifting 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.
The hydraulic lifting cylinder is not the same as the hydraulic lifting cylinder, because the pressure of the pneumatic system is generally within the range of 0.2-1.0Mpa, the hydraulic lifting cylinder can not be used as a high-power power component, but the hydraulic lifting cylinder can be used as a relatively large power component, or the hydraulic lifting cylinder system can be used.
Do not enter foreign bodies when installing the hydraulic lifting cylinder block. The place where the installation operation is carried out, the conditions are not good, and foreign bodies can be entered unconsciously. Therefore, the installation site must be cleaned up around, especially the place where the parts are placed must be cleaned, so that there is no dirt.
hydraulic lifting cylinder seal leakage causes and countermeasures: a. Loose tie rod nut will cause leakage, tighten the tie rod nut according to the torque requirements of tie rod nut, test no leakage can continue to use. b. Pressure exceeding the limit will also cause leakage. Replace the hydraulic lifting cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the hydraulic lifting cylinder. c. The hydraulic lifting cylinder seal is extruded, if the O-ring is obviously extruded at the hydraulic lifting cylinder seal, replace the hydraulic lifting cylinder seal.
Classification and application of cylinders.
Hydraulic cylinder is divided into single acting hydraulic cylinder, double acting cylinder, combined hydraulic cylinder, swing hydraulic cylinder. Single acting cylinder is divided into plunger type hydraulic cylinder, single piston rod hydraulic cylinder, double piston rod hydraulic cylinder, telescopic hydraulic cylinder. Plunger type hydraulic cylinder: the plunger moves only in one direction, and the return stroke is to push the plunger back using its own weight or load. Single piston rod hydraulic cylinder: The piston moves only in one direction, and the return stroke is to push the plunger back using dead weight or load. Double piston rod hydraulic cylinder: both sides of the piston are equipped with piston rods, and pressure oil can only be supplied to one side of the piston. The return stroke usually uses spring force, gravity or external force. Telescopic hydraulic cylinder: It obtains long stroke with short cylinder. The hydraulic oil is pushed out from large to small section by section, and the external force is reduced from small to large.
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.
