HF260D water well drilling machine in Malawi

The diesel engine drive the hydraulic motor, and the hydraulic motor run the drilling pipes and drilling bit. The drilling bit is Drill bit rotating and cutting soil.

The gasoline pump is working, and the water goes into the borehole through the drilling pipe, and flow out the borehole with mud together.

This is the drilling method of this drilling rig.

1. When you are drilling, please don’t always let the drilling bit go . If there are too many soil, it may block up the borehole, and the water can’t flow out the borehole. It will cause the mud pump leakage and damaged. Sometimes, you should rise the drilling pipes a little, and then go down again.

2. If The mud flowing out of the well is too thick, it is not good. You want to drill deeper and deeper, the most thing is let the mud flow out the borehole. If it is too much mud, and can’t flow out the borehole, it can’t drill deeper, so it need more water to dilute the mud or you clean the mud.

So, if the hydraulic motor is always working, and the drilling bit is always rotating, we could say the drilling machine is working normally. If you want to drill deeper, please must let the cutting soil and mud flow out the borehole with the water together.
