Zhengyuan water well drilling rig is an efficient top drive, fully hydraulic, multifunctional drilling rig widely used for drilling water wells, monitoring wells, precipitation wells, rescue wells, hot spring wells, ground source air conditioning holes, coalbed methane, natural gas, oil extraction and other projects. This drilling rig can use compressed air down the hole drilling or mud drilling in various formations in high-temperature, high-altitude, and plateau areas.
The Zhengyuan reverse circulation drilling rig adopts the latest RC drilling technology from abroad, and rock drilling dust can be effectively collected through a dust collector, avoiding environmental pollution. The slag can also be collected through a cyclone separator, which can be used for sampling and analysis work in geological exploration departments. It is the preferred equipment for geological exploration drilling and other deep holes.
The FSL400 drilling rig can use compressed air reverse circulation down the hole drilling on various formations. The lifting of the drilling rig frame, drilling frame compensation, drilling rod unloading, rotation and feed, support legs, hoisting, walking and other actions are all implemented by the hydraulic system, greatly reducing labor intensity, improving construction efficiency and engineering quality

During drilling operations, the drilling frame can increase its rigidity by compensating for the expansion and contraction of the oil cylinder and making contact with the ground,ensure the stability of the drilling rig during operation.
The compensating skateboard self-protection drill rod thread improves the service life of the drill rod.
The combination of drill rod extractor and hydraulic wrench ensures safe, convenient, and fast connection and removal of drill rods, reducing labor intensity degree, improve homework efficiency.
Design a unique drilling tool centering device, supplemented by a level, to ensure the drilling accuracy of the drilling rig. Centering device opening and closing comfortable and easy to use. The combination type clamp plate has a variable inner diameter that is absolutely compatible with the drilling tool.
Choose the latest patented product - air pre filter, which can filter out more than 90% of the dust in the intake and automatically
Dust removal, no need for cleaning, effectively reduces engine wear, extends service life, and improves work efficiency,
Make it truly suditable for various harsh working environments.
The specially designed oil mist device for the compression system can effectively improve the service life of the impactor.roller slide, wear-resistant and long-lasting.
