(UAE swager cylinder,produced by Hengyu Hydraulic Cylinder Factory）
swager cylinder are widely used in UAE，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed swager cylinder for customers from UAE.
The swager cylinder body is commonly made of No. 20, 35, 45 seamless steel pipe, and the steel pipe is honed or rolled to achieve the roughness requirement within 0.4μm. The low pressure swager cylinder can use 20 steel pipe, and the high pressure swager cylinder can use 45 steel pipe.
The assembly work of the swager cylinder has a great impact on the quality of the swager cylinder: each part must be carefully cleaned before assembly; To correctly install the sealing device everywhere: when installing the sealing ring, pay attention to its installation direction to avoid oil leakage due to installation, and its lip should be equipped with a pressure oil chamber. In addition, because it is a YX-shaped sealing ring, it is necessary to pay attention to distinguish between shaft and hole use, do not install wrong; Because the sealing device is matched with the sliding surface, an appropriate amount of hydraulic oil should be applied during assembly; The special wrench should be used when the threaded coupling is tightened, and the torque should meet the standard requirements; After the piston and piston rod are assembled, it is necessary to measure whether the coaxiality and straightness on the full length are out of whack. After assembly, there should be no blocking sensation and uneven resistance when the piston assembly moves.
Factors that should be considered when selecting the oil seal in the swager cylinder: some specific factors should be taken into account when selecting the oil seal in the swager cylinder, so as to have correct consideration and get accurate results, and then avoid wrong selection. The factors and aspects that should be taken into account are eight: swager cylinder diameter, piston rod diameter, piston rod and piston groove size, swager cylinder working pressure, swager cylinder movement speed, hydraulic system oil temperature and swager cylinder working environment.
The definition of the minimum starting pressure of the swager cylinder refers to the minimum working pressure of the swager cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the swager cylinder parts and the size of the sealing friction.
Is the hydraulic cylinder leaking because there is no pressure?
HC hydraulic cylinder common leakage reasons, first: most of the reasons are because the seal surface wear or aging leads to poor sealing, so there is no pressure to operate, as long as the piston seal can be replaced. Second: It may also be the piston rod strain, repair the piston rod is good. If it is because the piston strength is not enough and the playing time is long, it is necessary to replace the piston.
How to calculate the cross-sectional area of hydraulic cylinder?
Hydraulic cylinder cross section integral rod cavity and rodless cavity: rod cavity is cylinder inner wall cross-sectional area - piston rod cross-sectional area; The rodless cavity is the cross-sectional area of the inner wall of the cylinder. If the working pressure p and the output force F are known, the effective cross-sectional area A=F/p can be calculated.
