Working Principle of the Water Well Drilling Rigs Machine

The drilling machine works by pumping reverse circulation. Its working principle is: under the action of atmospheric pressure, the circulating fluid flows from the sedimentation tank through the return ditch to the bottom of the well along the annular clearance of the well hole. At this time, the rotary disk drives the drill pipe to drive the drill bit to drill. The negative pressure established by mud pump suction inhales the debris mud into the inner cavity of the drill pipe, then rises to the faucet, it is discharged into the sedimentation tank through the mud pump, the circulating liquid after the sediment continues to flow into the well hole, so that the drilling process of the reverse circulation is formed.

Drilling Machine Operation Essentials

1.Site selection:

Select the well location and wellhead location, dig the wellhead with a depth of 30-50cm and a diameter of 10-30cm. Move the installed frame above the wellhead to align. Generally speaking, the location of the wellhead is required to be dense, no bricks, gravel or firewood overhead, so as to avoid water seepage, collapse, sinking and the other phenomena during the drilling operation, resulting in hidden danger of safety.

2.Dig the reservoir:

About four meters away from the wellhead position ( or according to the actual terrain, the length of the water pipe ) to dig a diameter of more than 1.5 square meters and a depth of one meter impounding reservoir, the pressure water pump is horizontally suspended in the pool with wooden poles ( it is advisable to cover the water pump in the horizontal plane ) . Connect the other end of the pump tube to the faucet of the drilling machine.

3.Open the water well drilling machine:

The drill bit is linked and fastened with the drill pipe , the main control machine hoist raises the machine head,another person is connected to the first section of the drill pipe with the drill bit, the main control hoist slowly descends the machine head and the other person cooperates with the hand drill. The rod slowly places the drill bit through the base hole into the well hole, vertically straightens, then starts the drilling rig machine and the water pump. The drill rod rotates and enters the underground.
Remember: the drill bit is rotated in the clockwise direction when it is drilled and it cannot be reversed to avoid the drill pipe to slip out of the way.

4.Replace the drill pipe:

After the first section of the drill rod is driven, the matching person closes the safety button and inserts the rod card. The main control machinist opens the reverse gear and rotates the drill pipe counterclockwise. The lift head is separated from the drill rod; raise the machine head and take another drill pipe. The manual rotating top wire is connected with the machine head, the lower end joint is connected with the drill rod. Then the main control machinist starts to rotate clockwise to tighten the drill pipe, open the insurance card, remove the unload pipe card, start the clockwise rotation, continue to drill down. Repeat the above actions in this way. Find the ideal water-bearing geological sand layer according to the depth what you want.

5.Unloading drill pipe:

After drilling down to the aquifer of ideal depth, record the depth of the aquifer, stop the drilling rig, only open the pump to press the water to wash the sand. When the well is out without sediment, the drill pipe can be unloaded. First, connect the insurance buckle and insert the unloading pipe card, transfer machine head is separated from the drill pipe. Secondly, the unloader is mounted on the drill machine head, fastened, the lowering machine head aligns the unloader with the drill pipe on the base into the slot; and then rotates to hang and then lift, when the bottom joint of the drill pipe is raised above the safety card of the base, it stops and fasten the insurance buckle, insert unload pipe card, reverse turn and the drill pipe will be automatically removed. The person can take it off, repeated the operation.
Remember: when unloading the drill pipe with the drill bit, turn off the electric motor to manual and slowly raise the base port to avoid hanging.

Drilling Machine Routine Maintenance

1.The motor part of the drilling rig should be handled with care to avoid rain and splashing water.
2.The motor wire connector can not touch the power.
3.Always check if the wire rope is replaced.
4.Before and after use, the drill pipe wire should be lubricated with oil to place it in the rain shelter to avoid rust.
5.The motor can not be overload for a long time.
6.Check the circuit and transformer insurance when the motor does not work.
