1. Overview
A water well drilling rig is a device specifically designed for drilling and extracting water wells underground. It is a very important mechanical equipment in water conservancy engineering, which can help people obtain groundwater resources and provide important guarantees for agricultural irrigation, industrial production, and domestic water use.
2. Characteristics
Engine: Adopting Yuchai II stage engine, the engine is connected to the hydraulic pump through a high-strength elastic coupling in the middle, providing strong power for the drilling rig
Power head: The power head meets various drilling process construction requirements and has a fast footage speed. Hydraulic driving force head, using high load-bearing bearings, high drilling accuracy
Centralized Console: The design fully considers the convenience and comfort of human-computer interaction, with a simple and clear interface that is easy to use
Engineering track: Fearless of any terrain, efficient operation
Deep penetration, fearless of terrain, multi angle drilling
3.Cycle system maintenance
Mud pump (taking NOV 12-P-160 as an example)
Management of vulnerable parts
✔️ Piston lifespan: 200-300 hours (in hard formation conditions)
✔️ Valve seat sealing ring: Check the compression amount every 72 hours (replace if it is less than 1.5mm)
Washing standards
✔️ Immediately rinse the flow channel with clean water after stopping the pump (to prevent mud solidification)
✔️ Clean scale with 5% oxalic acid solution every week (soaking time ≤ 30 minutes)

Belt and chain adjustment: Regularly check the tightness of the drive belt and chain, adjust them in a timely manner to avoid slipping or excessive wear. Record adjustment parameters for future maintenance reference
Component cleaning frequency: Regularly clean the radiator and cooling system to prevent dust from clogging. Clean the air filter and keep the intake air unobstructed. Clean the surface of drilling tools, frames, and other components to reduce corrosion.
Filter replacement cycle
Regularly replace hydraulic oil and fuel filters according to the working environment and frequency of use. It is generally recommended to replace the oil every 200 hours of operation to maintain cleanliness and extend the lifespan of the equipment.
Lubrication requirements
According to the equipment manual requirements, regularly add designated lubricating oil to each lubrication point. Focus on lubricating high load parts such as transmission shafts and bearings to ensure sufficient lubrication and reduce friction losses. Record lubrication time and amount for tracking lubrication effectiveness
Daily insapection points
Check the appearance of the drilling rig for damage or abnormal wear, ensuring that all fasteners are not loose. Check if the electrical system connections are good and if the cables are not damaged. Verify the oil level observation of the hydraulic system for any signs of leakage. Monitor the engine running sound to ensure there is no abnormal noise. Check the wear and tear of drill rods, drills, and other tools, and replace damaged parts in a timely manner.
Quarterly excessive items: Conduct an unboxing inspection of the gearbox and gearbox, and replace worn parts. Check and replace aging seals to prevent leakage. Verify instruments and sensors to ensure accurate data.
Annual comprehensive maintenance: Conduct a comprehensive disassembly inspection, cleaning, inspecting, repairing, or replacing all components. Perform non-destructive testing on key components to prevent hidden faults. Update maintenance records and specify the maintenance plan for the next year.
Monthly maintenance tasks
Thoroughly inspect the electrical system and test whether all functions are normal. Check and adjust the hydraulic system pressure to ensure stable operation. Clean the sediment at the bottom of the fuel tank and keep the oil clean.
Component replacement plan
Based on the service life and maintenance records of the components, specify an annual replacement plan. Prioritize the replacement of vulnerable parts and critical components to ensure equipment reliability. Reserve commonly used spare parts to shorten maintenance cycles.
