虽然液压凿岩机已研制约15年了,但结构仍在变化。不同的制造商所利用的原理之间有显著的差异。利用液压而不是利用压缩空气去驱动凿岩机有许多确定的并被广泛报道的优点,主要归纳如下: 1.用于高的液压力驱动,可采用直径与钎尾直径接近的细长活塞,改进了传到钎杆上的能量,从而可获得较高的钻孔速度,通常为同规格的气动凿岩机的2～3倍。 2.靠调节冲击能、转速和推进压力可优化钻孔速度以及钎杆和钎头的寿命,使得钻单位孔深的投资额最低。 Although hydraulic rock drills have been developed for about 15 years, the structure is still changing. There are significant differences among the principles used by different manufacturers. There are a number of well-established and widely reported advantages of using hydraulics instead of compressed air to drive rock drills. The major ones are summarized as follows: 1. For high hydrodynamic drives, elongated pistons with diameters close to the diameter of the shank can be used to improve The energy transmitted to the drill rod, which can get a higher drilling speed, usually with the specifications of the pneumatic rock drill 2 to 3 times. 2. By adjusting the impact energy, speed and propulsion pressure can optimize the drilling speed and drill rod and bit life, making the drilling unit hole depth of the lowest investment.
