ST 350 Borehole Drilling Advantages
1. The machine can do both air drilling (with air compressor) and
water drilling (with mud pump).
2. The multifunctional drill rig of the geothermal well is an
improved device. Equipped with the Yuchai four-cylinder engine, the
drill rig meets national standards for emissions and the
environment. Meanwhile, the hydraulic system, supporting
configuration and appearance, etc. have been optimized, thus
improving the performance and working efficiency. The double
rotation motor increased the rotary torque and revolving speed.
3.The one-ton winch is optional for the multifunctional drilling
rig of the geothermal well, make the lifting easier. In addition,
the 1.5m supporting oil cylinder is also optional, making the
loading and transport convenient.
Bits Important Role During Drilling
Bit plays a very important role in the drilling of water well drilling rig, but the quality of a bit directly affects the efficiency and quality of water well drilling. Therefore, in the selection process, we should pay attention to the selection and use of lower bit. When we are operating the drill bit, we must pay attention to several aspects in order to better production and operation.
The maintenance of water well drilling rig needs to be carried out regularly
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.
