In submersible pump design, clear hole technology is a very important work. How to master its clear hole technology, the following for everyone to elaborate:
Submersible pump clear hole technology mainly draws on the gas lift type reverse rotation rotary drilling mud removal system. Due to the use of impact drilling machine into the hole, so the water pile mud requirements are not very high, are piling the process of self-made mud, but also because after the hole has been used to dig the large diameter particles have been excluded, so you can do the mud sucking jobs. The depth of the hose in the catheter connected to the conduit should be greater than 1.5 times the height of the head in the borehole to the mouth, and the duct is about 20-30 cm from the bottom of the hole.
Through the submersible pump on the vacuum suction of the mud, reducing the water level within the catheter, because the catheter and the water level within the pile to form a connector, so that the water quickly from the bottom of the catheter flock to the catheter, so that through the catheter hole on the pile bottom layer Upward pressure, the bottom of the pile into the catheter into the catheter and then into the rubber tube, and finally discharged by the submersible pump.
