(Peru swager cylinder,produced by Hengyu Hydraulic Co., Ltd）
swager cylinder are widely used in Peru，because of no need for deceleration device，smooth movement，long service life.So our company has designed swager cylinder for customers from Peru.
If the swager cylinder slips or crawls, please check whether there is astringency inside the swager cylinder, because the internal parts of the swager cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, the action resistance is too large, so that the piston speed of the swager cylinder changes with the different stroke position, and the slip or crawl occurs. Most of the reasons are due to poor assembly quality of parts, surface scars or sintered iron filings, so that the resistance increases, the speed decreases. For example, the piston is different from the piston rod or the piston rod is bent, the swager cylinder or the piston rod is offset from the mounting position of the guide rail, and the sealing ring is too tight or too loose. The solution is to repair or adjust, replace damaged parts and remove iron filings.
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.
When producing oil swager cylinders, there are two processing processes, grinding and rolling, the latter is better than the former. Rolling machining is a kind of non-cutting machining, using the plastic deformation of the metal at room temperature, so that the micro roughness of the workpiece surface is flattened to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve the two purposes of finishing and strengthening at the same time, which can not be done by grinding.
The wear of the hard chromium plating layer of the swager cylinder is mostly caused by the grinding of the friction iron powder of the piston, and the wear is faster when there is water in the middle. Corrosion caused by the contact potential difference of the metal only occurs in the part of the piston contact, and the corrosion occurs in a point pattern. As mentioned above, when there is moisture in the middle, it will promote the development of corrosion. Compared with castings, the contact potential difference of copper alloy is higher, so the corrosion degree of copper alloy is more serious.
How to disassemble the cylinder?
Generally speaking, it is not difficult to disassemble the hydraulic cylinder, as long as you are careful, but you often encounter some small trouble in the disassembly process, because the disassembly process is not correct. In fact, this can be avoided, as long as you follow below points. 1. Before removing the hydraulic cylinder, the hydraulic circuit should be relieved of pressure, otherwise, when the oil pipe connected with the cylinder is loosened, the high-pressure oil in the circuit will be rapidly ejected. When the hydraulic pressure comes back, the handwheel or pressure regulating screw at the relief valve should be loosened first, so that the pressure oil is unloaded, and then the power supply or power source is cut off, so that the hydraulic device stops running. 2. Disassembly should prevent damage to the top thread of the piston rod, the oil thread and the chrome layer on the piston rod surface.
Cylinder pressure calculation formula
The pressure of the cylinder at work is determined by the load, and the pressure of the physical force is equal to the force divided by the area of action (that is, P=F/S). If you want to calculate the output force of the cylinder, you can calculate it according to the formula: Set the radius of the piston (that is, the cylinder) is R (unit mm) the radius of the piston rod is r (unit mm) the working pressure P (unit MPa) the thrust of the cylinder F push =3.14*R*R*P (unit N) The pulling force of the cylinder F pull =3.14* (R*R-r* R) *P (unit N).
