ST 350 Water Well Drilling Rig Main Advantage:
1. five speed manual integrated gearbox, hydraulic release bearing and full synchronizer for gear shifting, with high reliability and long service life;
2. mechanical winch, which has fast lifting speed and is easy to deal with bottom hole accidents.
3. excellent off-road performance, especially in muddy areas.
4. four high-strength hydraulic legs, with a maximum support height of 1.5m, which is convenient for loading and moving of the drilling rig and reduces the hoisting cost. During drilling, the legs can also assist in leveling and stabilize the drilling rig.
Water Well Drilling Rig Working Process:
1. It is necessary to measure the distance during drilling. Generally, drill 10m each time or replace the drill bit, measure the drill pipe once, check the drilling depth, and modify it if necessary. Check whether the gearbox, bushing and vertical shaft gear are overheated and whether there is abnormal sound. If any problem is found, stop in time, find the cause and stop solving the problem.
2. When excavating with clean water, do not supply water before excavation. In addition, water can only be drilled after return. And make sure you have enough traffic. The rock powder in the hole takes a long time. Increase the water volume to prolong the service time of the pump, and wait until before drilling.
3. When replacing drilling tools, Changsha drilling platform is generally required to measure every 10m to change the drilling depth. Even if the gearbox, bushing, vertical shaft gear and other overheating phenomena occur, there will be no abnormal sound. If there is any problem, please stop immediately, investigate the cause and deal with it within a time.
