Safety precautions in the use of
water well drilling rigs
1. When the
water well drilling rig is parked or before firing, all switches should be in the "0" position, and the power supply should be cut off.
2. Before the operation of the water well drilling rig, the main and deputy drivers should contact to supply power.
3. When the
water well drilling rig operates at night, sufficient lighting should be ensured around the drilling rig.
4. When the water well rig is connected to the unloading rod, no one is allowed to stay in front of the platform, and the operator should wear a safety helmet.
5. Safety belts should be worn when working on the carriage.
6. Operators of water well drilling rigs must wear insulated shoes, and live mobile cables should be safe. It is not allowed to put the cable in water or put it on metal pipes.
7. When the water well rig is moving, the drilling tool should be raised to a certain height. And pay attention to whether the water well drilling rig is falling off, if it should stop immediately and take measures.
8. The forward and backward of the
water well drilling rig, and the forward and reverse rotation of the drilling tool, must be reversed after the main drive motor and the rotary motor stop rotating, so as not to cause electrical and mechanical accidents.
9. Check whether the cable is leaking. Whether the high-pressure air pipe and the joint are firm to prevent injury.
10. When adjusting the triplet of the water well drilling rig and reducing the pressure of the pressure reducing valve, first open the main air pipe vent valve to release a little high-pressure gas to avoid accidents.
Preparation before operation of
water well drilling rig
1. Lubricate according to the lubrication system and requirements.
2. Connect the air duct and power supply.
3. Walking operation of water well drilling rig: first check whether the transmission parts are well lubricated, loose or damaged, and whether the carriage is placed in the walking position. Only when the above requirements are met can the walking operation be carried out.
4. Landing carriage of water well drilling rig: The landing carriage is controlled by hydraulic system, and the working pressure is 13MPa. First, start the motor, and the oil pump supplies oil to each hydraulic control system. When the oil pump is working properly and the specified pressure value is reached on the pressure gauge, remove the pin on the carriage and the ear seat of the rack to operate the hydraulic operation valve to realize the carriage. Ups and downs. Water well drilling rigs should never operate the "straight or turn operation button" on the six-link button during the process of landing the carriage. After completing the carriage operation procedure, according to the needs of drilling, press the pin on the carriage and the rack to stop the oil pump motor. Before normal operation.
