(Nigeria yg series hydraulic cylinder,produced by Hebei Hengyu company）
yg series hydraulic cylinder are widely used in Nigeria，because of long service life，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed yg series hydraulic cylinder for customers from Nigeria.
If the yg series hydraulic cylinder piston rod is found to be worn, it can be brushed and plated first, then ground, and finally adjust the mating accuracy of the piston rod and the guide sleeve. At this time, the guide sleeve can be properly redrilled or the guide sleeve can be re-turned. When making the above repairs, remember to replace various rubber seals in time.
The definition of the minimum starting pressure of the yg series hydraulic cylinder refers to the minimum working pressure of the yg series hydraulic cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the yg series hydraulic cylinder parts and the size of the sealing friction.
Disassembly yg series hydraulic cylinder: When disassembly yg series hydraulic cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the yg series hydraulic cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the yg series hydraulic cylinder.
The yg series hydraulic 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 yg series hydraulic cylinder should pay attention to: the operation should be as far away from the yg series hydraulic cylinder as possible, to avoid falling objects, knocking, rubbing the yg series hydraulic cylinder coating. When cleaning the yg series hydraulic cylinder, only use soft materials (such as cotton) to wipe, and do not scratch high-hardness materials. Do not use the yg series hydraulic cylinder when the oil temperature exceeds 70 ° C.
A hydraulic system functions three cylinders to maintain pressure, what components need to be used?
Two way cartridge valve can be selected for control. Two way cartridge valve advantages: 1) flow capacity is large, especially suitable for large flow occasions. 2) The spool has sensitive action and strong anti-clogging ability. 3) Good sealing, small leakage, oil flow through the valve pressure loss is small. 4) Simple structure, easy to standardize.
What is the clearance between the cylinder and the piston?
The gap between the cylinder and the piston in the radius is generally 40 wires, that is, about 0.4mm, and the gap of the cylinder with different diameters will be slightly different. Generally, the inner diameter of the cylinder is larger than the outer diameter of the piston, so as to prevent the friction between the outer surface and the inner surface of the cylinder during the operation of the piston. In order to ensure that the cylinder has a rod cavity and a rodless cavity seal, a sealing device, that is, a sealing ring, is installed on the outer surface of the piston. The sealing ring form is not exactly the same, the O-type sealing ring is generally used under low pressure, and the lip sealing ring is used under high pressure. At the same time, the outer circle of the piston is also equipped with a dust ring and a wear ring. As long as the cylinder seal fails, all the internal seals should be replaced.
