What Are the Daily Checklist Items for a High Pressure Jet Drilling Rig?

Complete daily inspection checklists are the key to ensuring the safe and stable operation of high-pressure jet drilling rigs, which can effectively eliminate potential faults, avoid construction accidents and reduce equipment loss. The daily inspection covers power system, hydraulic system, high-pressure pipeline, grout system and safety protection, covering all core operating links.

First, conduct power and electrical system inspection. Check whether the power supply circuit is intact, whether the switch and cable are damaged, confirm the normal operation of the control panel and instrument display, and ensure sensitive and effective emergency stop devices. Second, inspect the hydraulic and lubrication system, check whether the oil level is standard, whether the oil quality is deteriorated, and whether the lubrication points are fully refueled to ensure smooth power transmission.

Third, inspect high-pressure pipelines, nozzles and sealing components, check for hose wear, pipeline leakage and nozzle blockage, and confirm firm joint fixation. Fourth, check the grout mixing and circulating system, clean filter screen impurities, test the operating state of the mixing pump and circulating pump, and ensure smooth fluid circulation. Finally, check the equipment fixing state and on-site safety protection facilities. After operation, clean equipment residues, record operating data and hidden danger information. Comprehensive daily inspection ensures zero-fault startup and safe operation of the equipment.
