一种打桩液压锤制造技术

一种耐高压的、无介质泄漏的、使用寿命长、锤击效率高和成本降低的新型打桩液压锤。在打桩液压锤的内长液压缸活塞块１和缸体１０、端盖２和活塞杆１１之间，采用介质压力从中空密封圈５、６的内腔７、８挤压密封圈体使其贴紧缸体１０和活塞杆１１而实现密封的新密封技术。由于ｎ形密封圈内腔中空，内长液压缸ｎ形密封圈５、６密封圈体和缸体１０、活塞杆１１之间摩擦轻微，磨损很小；密封圈体和缸体１０、活塞杆１１之间摩擦阻力小，提高了捶击工作的效率。本发明专利技术打桩液压锤不仅工作寿命成倍增加，无介质泄漏，能承受比现有打桩液压锤高的压力，提高了捶击工作的效率，而且成本较现有打桩液压锤大幅度降低。

Hydraulic hammer for piling

The utility model relates to a new pile driving hydraulic hammer which has the advantages of high pressure resistance, no medium leakage, long service life, high hammering efficiency and low cost. In the hydraulic piling hammer in long hydraulic cylinder piston block 1 and block 10, end cover 2 and a piston rod 11, a medium pressure from the hollow sealing ring 5, 6 7, 8 new cavity sealing technology of extruding the sealing ring body to make it close to 10 cylinder and the piston rod 11 sealed. Because the N shaped sealing ring cavity hollow, long hydraulic cylinder n sealing ring 5, 6 and 10 cylinder body sealing ring, a piston rod 11 between the friction wear is slight, very small; the sealing ring body and cylinder 10, a piston rod 11 between the friction, improves the efficiency of the thump. The invention not only the working life of hydraulic piling hammer increased exponentially, no leakage of the medium, can bear than the existing hydraulic piling hammer with high pressure, improve the efficiency of work and the cost is pounding, the existing hydraulic piling hammer greatly reduced.
