ST 300 Borehole Drilling Machine Drilling Attentions

 

Fully hydraulic control is convenient and flexible: can adjust the drilling speed, torque, and promote axial pressure, anti-axial pressure, propel and improve the speed to meet the different conditions use of drilling tools and different construction needs.
Multi-function drilling: A variety of drilling processes can be used on this rig, such as: DTH drilling, mud drilling, roller cone drilling, drilling with the follow-pipe and the being developed core drilling, etc. This drilling machine can be installed, according to user needs, mud pump, generator, welding machine, cutting machine. Meanwhile, it also comes standard with a variety of winch.
High working efficiency: thanks to full hydraulic and top drive rotary drilling, this drilling rig is adapt to a variety of drilling technology and drilling tools, has convenient and flexible control, fast drilling speed, short auxiliary time, and thus high operating efficiency.
Low cost: drilling on the rock is dominated by DTH drilling technology, DTH hammer rock drilling operation is high efficiency, drilling cost of per meter is lower.

 

St 300 Borehole Drilling Machine Rig Maintenance
 

I. maintenance of filter element:

The filter element plays the role of filtering impurities in the oil or gas circuit, preventing them from invading the system and causing faults; Various filter elements should be replaced regularly according to the requirements of (operation and maintenance manual); When replacing the filter element, check whether there is metal attached to the old filter element. If there are metal particles, timely diagnose and take improvement measures; Use the pure filter element that meets the requirements of the machine.

II. Lubricating grease Management:

The use of lubricating oil (grease) can reduce the wear of the moving surface and prevent noise. When the grease is stored, it shall not be mixed with dust, sand, water and other impurities; Lithium grease G2-L1 is recommended, which has good anti-wear performance and is suitable for heavy load conditions; When filling, try to squeeze out all the old oil and wipe it clean to prevent sand adhesion

III. fuel management:

Choose different brands of diesel oil according to different ambient temperatures; Diesel oil cannot be mixed with impurities, ash and water, otherwise the fuel pump will wear out prematurely; The high content of paraffin and sulfur in inferior fuel will damage the engine; After daily operation, the fuel tank should be filled with fuel to prevent water droplets on the inner wall of the tank; Open the drain valve at the bottom of the fuel tank to drain water before daily operation.
