The portable water well drilling rigs for sale in our company are collapsible drilling equipment. So it’s very convenient to carry and store. This kind of drill adopts the ball clip clamping mechanism, which can realize the continuous reverse lever and makes it easy to operate. In addition, its drilling function is compelling with 100 meters of drilling depth and the opening hole diameter can be up to 200mm. As long as your drilling needs are within this range, they can meet your requirements. So it’s usually the first choice for those customers who pursue simplicity and convenience. The complete set of equipment of the machine includes the main engine and some necessary tools, such as a drill pipe with a length of 40 meters, two drill bits, one high-pressure water pump, a high-pressure water pipe with a height of 5m, a power transformer of 60V,  one specification and one certificate. So if the technical parameter of the machine matches your needs, please send us an email to tell us more about your requirements and we will send you the quotation soon.
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.
