瑞典林登·阿利马克(Linden Alimak)公司所生产的AD-101液压凿岩机,在国际市场上销售量较大。1979年我局引进了H832C、L832C液压凿岩台车各一台。在H832C台车上配有两台AD-101液压凿岩机。在验收过程中,测绘了液压凿岩机的主要零件,并参阅了有关资料,发现它在结构方面有些特点,对于发展我国液压凿岩机有可借鉴之处,现介绍如下:(一)工作原理 AD-101液压凿岩机属单面进油、套阀型的,其工作原理分四个过程。
The AD-101 hydraulic rock drill produced by Sweden’s Linden Alimak Company has been sold well on the international market. In 1979, our bureau introduced one each of H832C and L832C hydraulic rock drilling trolley. The H832C trolley is equipped with two AD-101 hydraulic rock drills. In the process of acceptance, the main parts of the hydraulic rock drill were surveyed and referred to the relevant data and found that it has some characteristics in structure. For the development of hydraulic rock drills in our country, it can be used for reference, which are introduced as follows: (1) Working principle AD-101 Hydraulic rock drilling machine is a single side into the oil, sets of valve type, its working principle is divided into four processes.
