Several tips for getting started with rotary drilling rig quickly

Operation method of starting and drilling of rotary drilling rig

First, the strongest power is required at start-up, and low speed control is required during operation, so it is easy to overcome various resistances from static to dynamic. When some equipment is in operation, it still needs to accelerate and decelerate quickly， due to tonnage Heavier, when stopping, be sure to slow down first to reduce the impact of acceleration.

Second, the drilling technique is directly related to the geology of the construction: when drilling in the geology of the soil layer, the resistance encountered is relatively small, the highest performance of the rotary drilling rig can be used, and the high torque can quickly drill and improve Construction efficiency;When encountering sandstone layers, due to higher resistance While drilling with high torque, the rotary drilling rig needs to pay attention to increase the pressurized oil cylinder to maintain load balance and reduce resistance;in case of pebble layer, special attention shall be paid not to hard drilling. This kind of geological reaction is relatively strong. When drilling, slow pressure and low torque shall be applied to minimize the vibration;When encountering particularly hard and high-density geological conditions, after selecting the appropriate bit, steadily operate the drill to output and pressurize with large torque to overcome the resistance brought by drilling into the geological conditions.
