1. Water well drilling tools need to be cooled before repairing to avoid burns due to high temperatures. The hydraulic system of the drilling rig needs to be repaired after pressure relief to avoid danger caused by internal high pressure. When disassembling the main coil braking system of the drilling rig, it is strictly forbidden Reel load maintenance; when disassembling the right-twisted non-rotation-proof steel wire rope and connecting it with the lifter, pay attention to the mechanical rotation damage; when drilling, when the puller of the drilling rig does not rotate flexibly and the live wire rope is twisted with rotating force, it is necessary to prevent personnel from being caught Pinch. 2. When water well drilling tools are moving, the center of gravity should be kept balanced according to the road conditions and sites. Random drilling is prohibited on the construction site. Marks must be made for backfilling pits. Narrow roads or dangerous roads need to be walked with retractable crawlers, and the drilling rig needs to be adjusted on inclined roads with Mast lifting angle, left and right inclination, and turning on the car to adjust the center of gravity of the drilling rig; when there is water in the sidewalk or construction site, the drill bit can be used to guide the machine to drill wells.

　　Maintenance of water well drilling tools:

　　1. Maintenance of the filter element: the filter element plays the role of filtering impurities in the oil circuit or gas circuit, preventing them from invading the system and causing failure; all kinds of filter elements should be replaced regularly; when replacing the filter element, check whether there is metal attached to the old filter element, If metal particles are found, it should be diagnosed in time and improvement measures should be taken; use pure filter elements that meet the requirements of the machine.

　　2. Fuel management: choose different brands of diesel oil according to different ambient temperatures; diesel oil cannot be mixed with impurities, dust, and water, otherwise the fuel pump will be worn out prematurely; the high content of paraffin and sulfur in inferior fuel oil will damage the engine. Damage occurs; the fuel tank should be filled with fuel after daily operations to prevent water droplets from forming on the inner wall of the fuel tank; before daily operations, open the drain valve at the bottom of the fuel tank to release water.

　　3. Grease management: The use of lubricating oil (butter) can reduce the wear of the moving surface and prevent noise. When the grease is stored and stored, it should not be mixed with dust, sand, water, and other impurities; it is recommended to use lithium-based grease G2-L1, which has good anti-wear performance and is suitable for heavy loads; when filling, try to squeeze out all the old oil And wipe it clean to prevent sand from sticking.
