Water Well Drilling Rig

Water well drilling equipment is also known as a drilling machine for water. Its main function is developing groundwater resources, such as domestic water, agricultural water, and industrial water. It is also applicable to geological exploration, construction engineering, and drilling of bridge foundation. The working model of the water well drilling rig is pumping reverse circulation. Water wells have great significance in the development of human civilization. Humans could only live in places near lakes or spring water in the past. Nowadays, the emergence of water well has expanded the scope of human activities.

Water Well Drilling Equipment Structure

  1. Hydraulic oil pump: It is a double-type. The large-displacement pump provides powers for powerhead. The small-displacement pump provides powers for the four-legged cylinder, landing mast cylinder, and lifting cylinder.
  2. Four legs: adjust levelness and support the body of the drill rig.
  3. Mast: a frame structure welded for the combination of giant steel pipes, channel steel, and angle steel. Ensure the verticality of the hole. The ups and downs of the good mast are completed by the hydraulic cylinder.
  4. Powerhead: mechanism adopts the gear reducer. There is a large-diameter mandrel in the middle of the low-speed shaft. The upper end of the mandrel connects with the hose interface of the concrete pouring equipment, which can inject concrete. The lower end connects to the drill pipe and bit. High torque hydraulic motor drives the high-speed shaft.

How to Choose the Foundation of Water Well?

It is necessary to continuously drill for water well, therefore, this operation requires a stable production platform. The selection of the foundation of the water well rig is particularly important, and how to choose it, you should pay attention to the following aspects.

  • The foundation groove of the water well drilling rig should be excavated according to the stable slope. In particular, the collapsed strata should be dug into a stepped shape, so as to ensure stable production.
  • When the wellbore of the water well drilling rig sinks, it needs to maintain a smooth operation. Prevent the phenomenon of tilting of the wellbore, and correct the problem in time if it comes up.
  • When the water well drilling rig adopts the drainage method, the water level in the sinking well should decrease as the wellbore sinks. And it is generally required to control about 0.5-1 m below the excavation surface.
  • After drilling the water well, it is necessary to carry out drainage operation, so as to check the production quality of the water well drilling rig. The well needs to do a large deep pumping, and the stability of the water level needs to be maintained for about 8 hours. The purpose is mainly to ensure the water level and outflow of water well.
