(Greece tailplate hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）
tailplate hydraulic cylinder are widely used in Greece，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed tailplate hydraulic cylinder for customers from Greece.
tailplate hydraulic cylinder hydraulic oil selection: The recommended working oil viscosity of the tailplate 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.
Improve the service life of the tailplate hydraulic 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 tailplate hydraulic cylinder (such as the tailplate hydraulic 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 tailplate hydraulic 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 tailplate hydraulic cylinder inlet pipe (or return pipe) can be disassembled. Make the hydraulic oil overflow to achieve the effect of single tailplate hydraulic cylinder exhaust.
When the long-stroke tailplate hydraulic cylinder rotates horizontally, the piston rod bends due to its own weight, causing the guide sleeve and piston to produce biased load, resulting in tailplate hydraulic cylinder head seal damage, oil leakage, and piston sleep in the tailplate hydraulic cylinder. The following measures can be taken: increase the piston plan to adjust the piston outer circle and process it into a convex drum, so that the piston can self-position, improve the force situation, and reduce and avoid pulling the tailplate hydraulic cylinder; The piston and the piston rod are connected with a spherical joint.
The tailplate hydraulic 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 tailplate hydraulic cylinder can use 20 steel pipe, and the high pressure tailplate hydraulic cylinder can use 45 steel pipe.
The inner diameter of the injection cylinder is 203.2mm and the diameter of the screw is 63.5mm. What is the enhancement ratio?
Oil pressure multiplied by the cross-sectional area of the cylinder is equal to the theoretical output force value, and then multiplied by the efficiency of the cylinder is equal to the actual output force value, and the oil pressure can be calculated by inverting the value input.
Why is the cylinder not in place when the concrete pump truck changes the piston?
When the concrete pump truck changes the piston, the cylinder is not in place mainly because the transfer oil connecting the two cylinders is not completely drained. Sany and Zhonglian have a piston return switch, which can be used to back the piston to the cleaning tank. The elephant is equipped with a stop valve at the bottom of the oil cylinder, usually in the closed state, when opened, the piston can be returned to the cleaning tank, remember to close the valve after the piston is updated.
