Hollow-plunger缸FPT信号

液压 双作用 螺纹的身体

•CRI-FO系列是具有中空中心的圆柱体。专为电缆张紧操作、拉伸结构中的定位杆、滑轮组装和拆卸、吊装以及电缆和拉杆拉拔测试而设计。张紧棒，dywidag, macalloy。•带回油系统的行程可以比带弹簧回油的气缸更长。由于采用了回油系统，在所有工况下回油时间都缩短了。•带螺纹体气缸定位更容易，更准确，更安全。•止动环不仅最大限度地保证了操作人员的安全，防止柱塞过行程，而且还具有出色的偏心负载吸收能力。•中空，高强度，花键可拆卸头。•雨刮器减少了环和杆之间的污染。•重量超过20公斤的型号配备了手柄或提升螺栓，使其更容易携带。 Double acting oil return hollow plunger hydraulic cylinders in high pressure. Pushing force from 30 to 150 tons with a stroke range from 50 mm to 260 mm. Designed for cable tensioning operations, tensioning bars, assembly or disassembly. Operating pressure 700 bar. Guide surfaces are sized to guarantee optimal performance in absorbing the offset load and the end stroke ring increases safety for the operator by avoiding the extra stroke of the piston. Hydraulic jacks equipped with high strength gaskets for maximum durability up to 60° C, upon request it is possible to equip the cylinder with gaskets resistant to high temperatures up to 200° C. Furthermore, the presence of the wiper prevents contamination from impurities present in the environment of use.
