After installing the long tapered button bits, the power frequency and the pointer on the frequency switch in the control box should show the same ratio. If they are different, a variable frequency switch should be used for conversion. The drill rod is installed on the drill rig. The placement of the drilling rig should be stable and firm, and the tappet should be adjusted by automatic fine-tuning or wire hammer to maintain its vertical state. Before starting the tapered button bits operation, the joystick should be adjusted to the neutral position. In the process of using the drill pipe, if you find that the drill-down limit alarm signal is turned on, you must stop drilling in time, raise the drill pipe to a certain height, wait until the alarm signal is eliminated, and then you can continue drilling. Rod work. During operation, when you need to change the rotation direction of the tapered button bits, you must wait until the drill rod is safely stopped before continuing the operation.
When drilling the drill pipe, do not clean the dirt on the drill by hand. If you find that the strong bolt is loose, you also need to stop the operation of the tapered button bits immediately and continue the operation after tightening. After using the drill pipe, the tapered button bits and drill bit must be lifted from the hole, and the dirt on the drill pipe and spiral blade must be removed, and then the drill bit can be pressed to the ground. After braking this position, the joystick will be placed in the neutral position and the operating power will be disconnected.
With the development of mechanical alloying, rapid solidification technology has been developed rapidly. Due to the rapid development of geological drill pipes, the enhancement of fine crystals is very important. Deformation heat treatment can enhance the density of geological drill pipes and make them evenly distributed. Geological drill pipes can also be strengthened by fine grain strengthening and deformation.
