3. Woodworking Carpenters and woodworkers use spiral drill bits for their ability to create clean and precise holes in various types of wood. The smooth finish left by these bits is often essential for aesthetic purposes.

Features of Spiral Drill Bit Teeth

Whether in mining, construction, or waste management, the ZJ slurry pump proves to be more than just a piece of machinery—it is a cornerstone of operational excellence in an increasingly competitive industrial landscape.

Second, the use and characteristics of the drilling rig:
1). Use:
Engineering anchoring drill can be used in urban construction, railway, highway, river, hydropower and other projects to drill rock anchor hole, anchor hole, blasting hole, grouting hole and other drilling construction.
2). Features:
1, the drill selects the motor through the high-performance reducer as the reverse power; Use cylinders for propulsion. The hydraulic system is eliminated, so the mechanical efficiency is high, the cost is low, and the performance is stable.2, with anti-card maintenance, when the drill is stuck, the motor is not easy to burn, the reducer is not easy to damage.

The DTH hammer operates through a system of compressed air. High-pressure air is directed down the drill string, powering the hammer at the end of the drill bit. The hammer strikes the bit with considerable force, fracturing the rock immediately beneath it. As the bit penetrates further, the broken rock is then cleared from the hole by the same air stream, allowing for continuous drilling without the interruptions often associated with other drilling methods.

The pitman is a crucial component that transmits motion from the toggle mechanism to the movable jaw plate. It typically features a connection to the eccentric shaft, which causes the pitman to move in an elliptical arc. This movement is essential for achieving the force necessary to crush the materials effectively. The pitman must be robust and designed to handle the stresses of operation.

Cleaning method:
Fill the pump with water
Open the inlet door and clean the clogged part of the pipeline
Plug the leak area and check whether the packing is wet or compressed
