Water well drilling rigs is a series of machine for developing groundwater that people can use the drilling technology to extract groundwater to supplement the water demand of people’s daily life and production. The principles of different drilling equipment are different, which can be divided into the Dayton drilling technology and rotary drilling technology. In addition, there is a variety of water well drilling rigs for sale in YG Machinery, such as tractor-mounted water well drilling rigs, portable water well drilling machines, rotary drilling rigs, horizontal directional drilling rigs, crawler DTH drilling rigs, home water well drilling, etc… Pick up the suitable water well drilling equipment according to your requirements and contact us for more details now.
Small Water Well Drilling Rigs
As its name suggests, small water well-drilling rigs or mini water well drilling rigs are a kind of water well drilling rigs for sale in small sizes. We just need to equip different drill bits with the drilling machine for different geological situations. It has the advantages of fast drilling, convenient movement, and low price, which can drill the soil 30 to 40 meters in an hour. There are different models of small water well drilling rigs for sale with different drill pipe diameters, lengths, motor power, drill hole depth, pump power, maximum opening diameter, and so on. You can choose the model you want to be based on the image and parameters below.
Structure Composition of Water Well Drilling Rigs
  1. Hydraulic oil pump. The large displacement pump provides power for the powerhead, and the small displacement pump provides power for the four-leg oil cylinder, the lifting mast oil cylinder, and the lifting pulley oil cylinder.
  2. Four legs. Small water well drilling rigs consist of hydraulic oil cylinders and fixed frames that operators can adjust the level of the equipment at the worksite and play the role of supporting and stabilizing the body of the machine.
  3. Mast. It is a frame structure welded by a combination of giant steel pipe, channel steel, and angle steel. The inner slots of double-channel steel are used as the running track under the powerhead to ensure the perpendicularity of the drill hole.
  4. Powerhead. Use a gear reducer mechanism and there is a large-hole mandrel in the middle of the low-speed shaft. The upper end of the mandrel can be connected with the rubber tube interface of the concrete pouring equipment to conduct concrete pouring. The lower end of the mandrel connects with the drill pipe and drill bits through the flange. And the high-speed shaft is driven by a large torque hydraulic motor.
System Composition of Water Well Drilling Rigs:
  1. The power system can provide power equipment for the whole machine.
  2. The work system can work according to process requirements.
  3. The transmission system is used to transfer and allocate energy for the working unit.
  4. The Control system can control all systems and equipment, as well as coordinate the work according to the process requirements.
  5. The auxiliary system assists the main system.
The Maintenance of the Water Drilling Machine:
  1. Always check whether the wire rope is replaced;
  2. Pay attention to its continuous use time, the motor can’t be overcharged for so long time;
  3. The motor part of the drills should be carefully handled and avoid raining and splashing water when you need to move the machine.
  4. The drill pipe thread should be lubricated and placed in the rain shelter to avoid rust;
  5. The electric motor wire connection shouldn’t touch the electricity when you don’t use it;
  6. Check the circuit and transformer insurance when the motor doesn’t turn.
How Do the Water Well Drilling Rigs Work?
The work mode of water well drilling rigs is pump-suction and reverse circulation. Under atmospheric pressure, circulating liquid flows from the sedimentation tank to the bottom of the well along the circular gap of the good hole through the back ditch. At this point, the rotary disk drives the drill pipe and rotates the drill bit rotation for drilling. Then the negative pressure established by the mud pump suction draws the debris mud into the inner cavity of the drill pipe and rises to the faucet. And then it is discharged into the sedimentation tank through the mud pump. The circulating liquid continues to flow into the hole after precipitation, and so on, forming a reverse-circulation drilling operation.
