Qatar hydraulic cylinder,lift cargo elevator hydraulic cylinder manufacturer,lift cargo elevator hydraulic cylinder(Qatar lift cargo elevator hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory)
lift cargo elevator hydraulic cylinder are widely used in Qatar,because of powerful torque,excellent temperature resistance,no transmission clearance.So our company has designed lift cargo elevator hydraulic cylinder for customers from Qatar.
The method of sleeve lift cargo elevator hydraulic cylinder to improve the processing quality: there is a big gap in the service life of post-plating polishing and post-plating polishing, especially in mass production. Strictly clean the flying edge and burr of mechanical components, especially the edge of the sealing groove, and the tiny metal burr, strictly clean before assembly. The surface fatigue strength and stress corrosion resistance of the lift cargo elevator hydraulic cylinder can be significantly improved by rolling in the finishing of the inner holes of the lift cargo elevator hydraulic cylinder. The roughness of the surface of the friction pair is generally controlled between Ra0.4 and 0.8.
The viscosity of the working oil used in the lift cargo elevator hydraulic cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.
lift cargo elevator hydraulic cylinder hydraulic oil selection: The recommended working oil viscosity of the lift cargo elevator hydraulic cylinder is 10 ~ 110cSt (1.8 ~ 15E), ISO VG46 hydraulic oil. The normal working oil temperature is 10 ~ 70℃, and the ambient temperature is in the range of -20 ~ 80℃. When the ambient temperature and service temperature are low, the hydraulic oil with lower viscosity can be selected.
The pressure of the sliding surface of the lift cargo elevator hydraulic cylinder piston is too large, resulting in sintering. The piston tilts due to the weight of the piston rod, resulting in the phenomenon of non-stiffness, or the pressure of the sliding surface of the piston rises due to the action of the transverse load, which will cause sintering. In the design of the lift cargo elevator hydraulic cylinder must study its working conditions, the length of the piston and bushing and the size of the clearance must be fully paid attention to.
What diameter cylinder is needed for a force of 5 tons?
It depends on the pressure of your system pump. If the normal working pressure of the system is about 8MPa, then the diameter of the cylinder should be 100 mm.
How to take out the diaphragm of hydraulic cylinder? The septum ring is also known as the septum sleeve, when the cylinder is too long, and does not need too much travel, add the septum sleeve, limit the stroke of the hydraulic cylinder, set on the piston rod, only contact with the guide sleeve and piston, do not cooperate with the cylinder, limit the stroke, take out the difficulty is different, need to have such a professional tool, before taking out to consult the manufacturer.
