液压凿岩机凿岩过程中,必须保证有效的润滑,岩孔必须得到良好的冲洗,才能使液压凿岩机发挥出应有的性能及效率。本文在介绍液压凿岩机供水和润滑系统基础上,分析其漏油、漏水的原因,并提出维护保养要点。1.供水系统和润滑系统(1)供水系统液压凿岩机大多采用旁侧供水结构,如图1所示。冲洗水通过凿岩机前部的冲洗头2,从钎尾4的进水孔进入到钻杆内,再从钻杆头部输出,对所钻岩孔进行冲洗。该种结构的优点是水路短、易实现密封、水压大(可达1MPa以上),发生漏水后,对凿岩机内部润
During hydraulic rock drilling, it is necessary to ensure effective lubrication. The rock holes must be well washed to make the hydraulic rock drill work properly and efficiently. This paper introduces the hydraulic rock drill water supply and lubrication system, based on the analysis of the reasons for the oil leakage, leakage, and put forward the main points of maintenance. 1. Water Supply System and Lubrication System (1) Water Supply System Hydraulic rock drills are mostly provided with side water supply structure, as shown in Figure 1. The flushing water passes through the flushing head 2 at the front of the rock drill, enters the drill pipe through the water inlet hole of the shank 4, and then is output from the drill pipe head to flush the drilled hole. The advantages of this structure is the short waterway, easy to seal, water pressure (up to 1MPa above), the occurrence of leakage, the internal drilling Run
