HQZ（260L/300L）气动水井钻机（履带）
HQZ（260L/300L）Pneumatic Water Well Drilling Rig（Crawler）
我公司水井钻机是一种顶驱式高效、多功能全液压钻机，具有技术先进、使用方便、作业效率高，可靠耐用等特点，广泛适用于钻凿水井、检测井、降水井、救援井、地源空调孔、煤层气、天然气、石油开采及其它工程，该钻机可在各种地层采用压缩空气潜孔钻进，在普氏硬度f=4-20范围的岩石中钻孔有很高的钻进速度。
Our company's water well drilling rig is a kind of top driven high efficiency and multifunctional hydraulic drilling rig with advanced technology, convenient operation, high working efficiency, reliability and durability. It is widely used in drilling wells, inspection wells, precipitation wells, rescue wells, Ground source air conditioning holes, CBM, natural gas, oil extraction and other projects. this machine can drill holes with air compresse in all formations , the drilling speed is very fast when drill the hard rock , which hardness is f=4-20.
HQZ系列钻机功能特点是机身小巧。机身宽度只有1.9米，完全适合为农家院落入户打井或其他狭窄地况钻井。钻井深度可达240-300米。
HQZ series drilling rig has the compact body. The fuselage width only 1.9 meters, fully suitable for farming courtyard home drilling or other narrow condition drilling. Drilling depth up to 240-300 meters.
全液压操控方便灵活：可随时调整钻机的转速、扭矩、推进轴压、反轴压、推进速度、提升速度，以满足不同钻具使用工况和不同施工工艺的需求.
Fully hydraulic control is convenient and flexible: can adjust the drilling speed, torque, and promote axial pressure, anti-axial pressure, propel and improve the speed to meet the different conditions use of drilling tools and different construction needs.
顶驱式回转推进提升：便于钻杆接卸，缩短辅助时间，还有利于跟管钻进。
Top drive rotary drilling: easy to install and remove the drill rod, shorten the auxiliary time, and fasten the drilling of follow-pipe.
多功能钻进：各种钻进工艺都可以在这种钻机上使用，比如：潜孔钻进、泥浆钻进、牙轮钻进、跟管钻进以及正在研发的岩芯钻进等等。钻机可根据用户需求加装泥浆泵、发电机、电焊机、切割机。钻机还标配有各种卷扬机。
Multi-function drilling: A variety of drilling processes can be used on this rig, such as: DTH drilling, mud drilling, roller cone drilling, drilling with the follow-pipe and the being developed core drilling, etc. This drilling machine can be installed, according to user needs, mud pump, generator, welding machine, cutting machine. Meanwhile, it also comes standard with a variety of winch.
作业效率高：由于全液压和顶驱式回转推进提升，适应于各种钻进工艺和各种钻具，操控方便灵活，钻进速度快，辅助时间短，因而作业效率高。
High working efficiency: thanks to full hydraulic and top drive rotary drilling, this drilling rig is adapt to a variety of drilling technology and drilling tools, has convenient and flexible control, fast drilling speed, short auxiliary time, and thus high operating efficiency.
成本低：在岩石上的钻进以潜孔锤钻进工艺为主，潜孔锤岩石钻进作业效率高，单米钻进成本最低。
Low cost: drilling on the rock is dominated by DTH drilling technology, DTH hammer rock drilling operation is high efficiency, drilling cost of per meter is lower.
高支腿履带式：高支腿便于装车运输，不需要吊车可直接装车。履带式行走更适应于泥泞的现场移动。
High leg crawler type: high leg is easy for loading and unloading, no need of crane in truck loading. Crawler walking is more adapt to the movement in muddy field.
油雾器的作用：在岩石上的钻进以潜孔锤钻进工艺为主，潜孔锤岩石钻进作业效率高，经过润滑的冲击器使用寿命更长，单米钻进成本低。
The role of the oil mist: drilling on the rock is dominated by DTH drilling technology, DTH hammer rock drilling operation is high efficiency, lubricated impactor has longer service life, drilling cost of per meter is lower.
钻机底盘：可以是履带式自行底盘，也可以是车载式自行底盘。
Drilling rig chassis: It can be crawler chassis, and also be truck-mounted chassis.
