| The drill pipe is a product of machinery parts, the most common is in the process of the exploitation of oil and gas, and can be repeatedly used for drill pipe, we request that requires a strong ability to take pressure, free to twist, bending and vibration, in general we common pipe can reach nine meters.
At the bottom of the drill stem is threaded to the common steel pipe, drill pipe is mainly used for connecting the drill ground equipment and drilling drilling and grinding equipment is located in the bottom or bottom hole device. We used the drill pipe and borehole in use. The drill pipe is divided into many types such as coal drill pipe, drill pipe, a water model of wind pipe and so on, according to different requirements, can provide different drill to meet industry demand.
Screw drill is mainly composed of a bypass valve, hydraulic motor and drive shaft, Wan Xiangzhou and so on four big assembly. The screw motor is the main component of drilling tools, a lot of practical and theoretical analysis results show that, if you want to make the motor work effectively, the pressure drop of each motor can withstand preferably not more than 0.8Mpa, otherwise the motor leakage. Speed decreases quickly, serious when completely stop the rotation, the motor damage. (a lead motor as a mud flow field use) should be used in the recommended range, otherwise it will affect the efficiency of the motor, or even increase the wear. The performance parameters of the screw motor is the main performance parameters of screw drill. The motor output torque and the motor theory of pressure drop is proportional to the input, output and mud flow rate is proportional to the speed, with the increase of load of drilling speed is reduced, so as to control the reading and pump pressure gauge on the ground traffic, you can control the torque and rotational speed of drilling tool. | | | Published at: 2017-10-09 09:19:10 |  |
