Qatar hydraulic cylinder,vehicle hydraulic cylinder manufacturer,vehicle hydraulic cylinder(Qatar vehicle hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory)
vehicle hydraulic cylinder are widely used in Qatar,because of high work efficiency,excellent fatigue and impact resistance,no need for deceleration device.So our company has designed vehicle hydraulic cylinder for customers from Qatar.
The piston rod of the vehicle hydraulic cylinder has two kinds of solid rod and hollow rod, and one end of the hollow piston rod needs to be set aside for welding and heat treatment. The solid piston rod material is 35, 45 steel, and the hollow piston rod material is 35, 45 seamless steel pipe. After rough machining, the piston rod is conditioned to 229~285HB in India, and if necessary, the hardness is 45~55HRC after high-frequency quenching.
The scar on the sliding surface of the vehicle hydraulic cylinder piston will transfer with use. Before the piston is installed, there are scars on its sliding surface, which are installed intact and untreated, and these scars will in turn scratch the inner surface of the vehicle hydraulic cylinder wall. Therefore, before installation, these scars must be fully repaired.
If the seal of the vehicle hydraulic cylinder is softened and sticky, it may be that the seal is incompatible with the hydraulic oil or the nearby lubricating oil, replace the appropriate seal; If the seal becomes hard and loses elasticity, most of it is because the ambient temperature is too high (more than 80 ° C), make appropriate temperature insulation protection or replace the high temperature seal.
Disassembly vehicle hydraulic cylinder: When disassembly vehicle hydraulic cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the vehicle hydraulic cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the vehicle hydraulic cylinder.
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.)
100 tons press, the cylinder diameter is 250, how much pressure?
100 tons hydraulic press, if it is a single acting hydraulic cylinder, the required oil pressure is the nominal force divided by the cross-sectional area of the cylinder piston. One hundred tons of its pressure is 1000 kN (1000000N), the diameter of the cylinder is 250 mm, its area is the circular rate multiplied by the square of the radius, is 49062.5 square mm, and then the pressure divided by the area of the oil pressure is 20.38MPa. Therefore, a hydraulic pressure of 20.38 mpa is required for a 250 diameter cylinder to obtain 100 tons of pressure.
