Precautions during operation of Water Well Drilling Rig
As large-scale projects proliferate across the nation, the utilization of various drilling rigs, particularly Water Well Drilling Rigs, has become commonplace. These rigs are primarily employed for drilling water wells and performing related tasks such as inserting downhole pipes and well cleaning. Their operation is straightforward; however, ensuring safety is paramount. Below are essential precautions to follow when operating a Water Well Drilling Rig:
Operators must undergo specialized training and possess relevant work experience before being permitted to operate the drilling rig.
Drillers should be proficient in the drill's operational techniques and possess comprehensive maintenance knowledge, along with significant experience in diagnosing and resolving issues.
Prior to transporting the drilling rig, a thorough inspection must be conducted to ensure all components are intact, cables are free from leaks, and drill pipes and tools are undamaged.
The drilling rig must be securely installed, with slow and steady movements around corners or ramps, and secured with steel wires where necessary.
Upon arriving at the construction site, the drilling rig should be firmly fixed. The drilling area should exceed the size of the rig's base, providing ample safe space around it.
Drilling operations must strictly adhere to predetermined hole positions, orientations, angles, and depths. Unauthorized modifications by the driller are strictly prohibited.
Before installing drill pipes, inspect them to ensure they are not obstructed, bent, or have worn threads. Unqualified drill pipes must not be used.
When loading and unloading drill bits, take care to prevent the pipe clamp from damaging the cemented carbide inserts and avoid damaging flat drill bits and core tubes.
Drill pipes should be installed sequentially, ensuring the first pipe is securely in place before installing the next.
When drilling with clean water, ensure a continuous water supply before commencing drilling. Pressure drilling should only begin after water returns, and a sufficient flow rate must be maintained. Drilling dry holes is prohibited. If excessive rock powder accumulates in the hole, increase the water volume and extend pumping time until the hole is thoroughly cleared before stopping drilling.
Accurate measurement of drilling distance is crucial. Measurements should be taken every 10 meters of drilling or when changing drilling tools, using drill pipes to verify hole depth.
Regularly monitor the gearbox, shaft sleeves, and horizontal and vertical shaft gear for overheating or abnormal noises. If any issues are detected, immediately shut down the machine, identify the cause, and address it promptly.
