本文介绍了国内首先研制的JZ—40型减振器的设计原理及部分现场试验资料,以及用于牙轮钻机后所带来的经济效果,供有关人员参考选用。 JZ—40型减振器可以用在各种钻凿Ф250毫米炮孔的牙轮钻机上。经在鞍钢眼前山铁矿的45R型钻机和YZ—35型钻机上的钻孔实验证明,效果显著,达到了设计要求,1982年通过鉴定,同意定型,批量生产,推广使用。该减振器在牙轮钻机上的应用为国内首创。
This article introduces the design principle and some field test data of the JZ-40 shock absorber first developed in China, as well as the economic effects brought by the use of the roller cone drilling rig for reference and selection by relevant personnel. JZ-40-type shock absorber can be used in a variety of drilling Ф250 mm gun hole drilling rig. The results of drilling experiments on 45R drilling rig and YZ-35 drilling rig at Anshan Iron and Steel Company’s Yananshan Iron Mine proved that the effect was remarkable and reached the design requirements. In 1982, it was approved and stereotyped, mass-produced and popularized. The application of the shock absorber on the roller rig is the first in China.
