Hydraulic Power Head Disadvantages of Water Well Drilling Rig

Disadvantages: Compared with mechanical rotary drilling Machine, the hydraulic well drilling rig also has the following limits. The cost is relatively high: most of the fully hydraulic drilling machine is truck mounted type. The drilling rig should implement different drilling processes and realize quick operation cement mixers, so the equipment is complex and large. What’s more, for the head rig adopts hydraulic drive, various hydraulic components and high quality requirement of the hydraulic components, the drilling machine cost is much higher than ordinary rotary drilling machine;

Henan Daswell Machinery Co., Ltd,is a professional manufacturer and trader specializing in the research, development and production of construction machinery for nearly 30 years. Our main products are as follows:concrete mixers,diesel mobile concrete mixer,mini concrete batching plant for sale,etc. We will provide you with the best product and service.

Maintenance difficulties: rotary drill is given priority to mechanical drive, which is not prone to mechanical failure. But for the hydraulic drilling rig Diesel Concrete Mixer, hydraulic systems tend to have hundreds of hydraulic pipeline and dozens of working valve group. So if any failure happens, it is difficult to diagnose the problem parts and do maintenance works;

Low drilling efficiency: the height of truck mounted water well drill rig’s mast is limited and drilling stem is usually shorter Sicoma Planetary Concrete Mixer, so it doubles the drilling times. Compared with other drilling machine with derrick, the hydraulic well drilling rig‘s work efficiency is low. And with the continuous increase of hole deep, the influence of pipe length of construction time is gradually obvious.
