In order to improve the service life of the Water Well Drilling Tools, daily maintenance of the central cable drill pipe is required.
 
1) After using the drill pipe, it should be checked in time, and if any problem is found, it should be recorded and dealt with in time.
 
2) After the cumulative footage of the drill pipe reaches 20000m or the service life reaches one year, the overall performance of the drill pipe needs to be inspected. The inspection items should include: ① the wear of the drill pipe thread; ② the wear of the drill rod body; ③ whether the plastic male and female joints are loose or other defects; ④ whether the sealing ring on the plastic male and female joints is intact; ⑤ the positioning retaining ring Whether there is any deformation or cracks; ⑥ the resistance of the device; ⑦ check whether the stainless steel column joints and cone joints are corroded.
 
The drill pipe body is the component of Water Well Drilling Tools that transmits pressure and bears the torque. If the drill pipe thread is worn severely or the drill pipe body wears more than 2mm in the diameter direction, it should be scrapped; Water Well Drilling Tools has long-term disturbance in the flushing fluid and other It is easy to damage under the corrosive action of the medium, so the corresponding parts should be replaced and maintained, and the drill pipe maintenance records should be kept.
