(Guatemala swager cylinder,produced by Hengyu Hydraulic Co., Ltd)

swager cylinder are widely used in Guatemala,because of no transmission clearance,simple structure and reliable operation,excellent temperature resistance.So our company has designed swager cylinder for customers from Guatemala.

Introduction to swager cylinder:

How to determine the working pressure of the swager cylinder: The pressure depends on the load size (i.e., F) and the type of equipment. The limitations of assembly space, economic conditions and component availability of the actuator should also be considered. In the case of a certain load, it is necessary to increase the structural size of the actuator if the working pressure is low, for some equipment, the size may be limited, and it is not economical from the point of view of material consumption; On the contrary, if the pressure selection is too high, the material, sealing and manufacturing accuracy of the pump, swager cylinder, valve and other components are also required to be high, which will inevitably increase the cost of equipment. In general, for equipment with a fixed size that is not too limited, the pressure can be selected lower, and the walking machinery should be selected higher.

Improve the service life of the swager cylinder: it is necessary to maintain the normal clearance of the combined surface of the hydraulic components. When manufacturing or repairing the main parts of the swager cylinder (such as the swager cylinder block, piston rod, etc.), the assembly should be carried out in accordance with the tolerance lower limit of the assembly size, which can well reduce the occurrence of cavitation. If cavitation has occurred in the hydraulic components, only metallographic sandpaper polishing technology can be used to remove cavitation pitting and surface carbon deposits, and general fine sandpaper must not be used for polishing After the swager cylinder is repaired, the hydraulic system should run smoothly for a certain period of time so that the hydraulic oil in the hydraulic system can be fully circulated; If necessary, the swager cylinder inlet pipe (or return pipe) can be disassembled. Make the hydraulic oil overflow to achieve the effect of single swager cylinder exhaust.

The swager cylinder is mainly composed of body, piston, piston rod, swager cylinder head, swager cylinder bottom, piston rod head and related auxiliary devices. The piston divides the swager cylinder into two chambers, and moves reciprocally in the swager cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the swager cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the swager cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the swager cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the swager cylinder bottom and the swager cylinder head is serious, so the buffer deceleration should be set at both ends of the swager cylinder The working medium of the swager cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; swager cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the swager cylinder: The buffer structure of the swager cylinder is to prevent the piston from colliding with the swager cylinder head at the end of the stroke.

In the case of serious wear on the inner surface of the swager cylinder, or when there is a deep longitudinal tensile mark, it should be mapped according to the physical object and re-produced by the professional manufacturer according to the swager cylinder manufacturing process for replacement. The swager cylinder can also be repaired with TS311 antiwear repair agent. TS311 anti-wear repair agent is mainly used for the repair of worn and slipped metal parts.

Answers to some questions about swager cylinder:

What is the safety factor of 25MPa cylinder wall thickness?
Safety factor n can take 3 cylinder material allowable stress [s]=sb/n δ/D=0.08 ~ 0.3 cylinder wall thickness δ=PMAX*D/ (2.3[s]-3PMAX) δ/D≤0.08 cylinder wall thickness δ=PMAX*D/2[s] P < 16MPa, Pmax=1.5Pn; P > 16MPa, Pmax=1.25Pn cold-drawn tube or honing tube is better!

How is the cylinder of hydraulic cylinder processed?
As the main parts of hydraulic cylinder, mining single pillar, hydraulic support, gun barrel and other products, its processing quality directly affects the life and reliability of the whole product. Cylinder processing requirements are high, the internal surface roughness requirements are Ra0.4 ~ 0.8&um, the coaxiality, wear resistance requirements are strict. The basic feature of cylinder is deep hole processing, which has always troubled the processing personnel. Due to the residual compressive stress on the surface of the surface layer, the rolling machining is helpful to seal the small cracks on the surface and prevent the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the cylinder can be improved.
