1 What is drilling Tip ?
-----It is the drilling bit at the end of the drilling pipe,it can decide the diameter of the well.
We can customize the drilling bit according to your requirement.
2 What is drilling Pipe(rod) ?
-------It deccides how deep you can drill a well,the material is galvanized steel.OD(outer diameter) is 42/50mm.
3 Why do you use a transformer ?
-----The motor used is electrical Direct Current,we will configure a voltage transformer to change the alternating current to 60V direct current.
The driving force of direct current is strong enough for the very hard soil,it also can protect the operator in case of electricity leakage.
Direct Curret is more stable and safe,the lifting strength is also more than the Alternating Current.
The transformer can turn 220V or other voltages Alternating Current to 60V Direct Current.
4 Can we use a 220volts alternating motor for a direct use without a transformer? If no,why?
We do not advise you to use 220 Volts directly,there are two reasons:
----First:220V alternating current is not stable,and the driving force is not as strong as the direct current.Sometimes you will meet the very hard soil,so you had better use the 60V direct current.
----Second:in case of the electricity leakage,220V voltage has more harm than 60V.
5 What is the suction water pump?
------With the high pressure,It is used to draw the sand,soil and other residues out of the well,and can clean the well after the well is finished.
