What is included in the loose parts of a water well drilling rig

 Water well drilling rigs loose parts contain a very large number of components, depending on the type and size of the rig, the specific configuration will vary. But generally speaking, its main components can be summarized as follows:


1. Host part: This is the core part of the drilling rig, mainly including:
Power system:
Diesel engine/electric motor: provides the power source for the operation of the drilling rig. Diesel engine is commonly used in field operation, while the electric motor is suitable for places with power supply.
Transmission system: including clutch, gearbox, reducer, etc., used to transfer and regulate the power output.

Rotary System:
Rotor/Power Head: Drive the drill pipe and drill bit to rotate and break the rock. The power head is usually hydraulically driven, which can realize stepless speed change and large torque output.
Vertical shaft/spindle: Connects the rotator with the drill pipe and transmits the rotary motion.

Feed system:
Feed mechanism: Controls the speed and pressure at which the drill bit drills downward. Common feeding methods include hydraulic feeding, mechanical feeding, etc.
Feed cylinder/screw: Provides feed power to push the drill bit downward.

Winch system:
Winch: Used for lifting and lowering drilling tools, casing, etc.

Rope/pulley set: Used in conjunction with the winch to realize the lifting and lowering functions.

Hydraulic system (if hydraulic drive is used):
Hydraulic pump: Provides hydraulic power.
Hydraulic valves: control the flow and pressure of hydraulic oil.
Hydraulic tank: storage of hydraulic oil.
Hydraulic piping: connects the various hydraulic components. 2.

2. Drill Tower: Used to support the lifting mechanism and drilling tools, commonly:
Mast/Derrick: Supports winches, pulley blocks, etc. and provides lifting space.
The overhead crane/wheelbarrow is mounted on top of the mast and is used to suspend the pulley block.

3. Drilling tools: tools directly involved in rock breaking and sampling, including:
Drill pipe: connects the drill bit to the rotator, transmits rotary motion and pressure.
Drill Bit: A tool for rock crushing, different types of drill bit are selected according to the lithology of the stratum, such as tooth wheel drill bit, PDC drill bit, diamond drill bit and so on.
Drill collar: Weights the drill pipe and provides drilling pressure.
Casing: Used to protect the well wall and prevent it from collapsing.

4. Circulation system: Used to remove rock chips from the bottom of the well, cool the drill bit and maintain the stability of the well wall:
Mud pump/water pump: Provides the circulating medium (mud or water).
Mud sump/tank: stores the circulating medium.
Pipes/taps: Connect the various circulating elements.
Drilling fluid/fresh water: Circulating medium.

How to extend the life of drill pipe

  1. When using a new drill pipe, the drilling rig manufacturer should make sure that the wire fasteners on the front cut-off (protecting the shaft head) of the drill bit are also close to the new one. A ring-buckled rotating head can easily damage the wire fasteners of the new drill pipe, resulting in leaks, snaps, and loosening, and so on. 2. In the use of drill pipe for a drilling, should be first “grinding new buckle”, which consists of, first smeared with silk buckle oil, and then use the drill rig full torque, and then open the buckle, and then smeared with silk buckle oil and then open, and so on for three times, you can avoid the new wear and buckle. 3. As far as possible to maintain the drill pipe under the ground and on the ground in a straight line, so as to avoid part of the side of the wire buckle force and cause unwanted wear and tear, or even jump buckle, pay attention to the rig anchored to avoid the construction of the force to move is very important. 4. The buckle...

What are the Basic Maintenance Methods for Water Well Drilling Rigs

  Cleaning: After every day's operation, clean the mud, oil, and other debris on the rig in time to keep the rig clean. Checking lubrication: regularly check  the lubrication points to ensure that the lubricant is sufficient and the grease is clean. Fasteners check: you can check whether the bolts and nuts of each part are loose and tighten them in time. Hydraulic system checks: you can check whether the hydraulic oil level is normal, whether there is no leakage phenomenon, and whether the hydraulic oil is clean. Lubrication system maintenance: regular replacement of lubricating oil, grease, cleaning oil filter, and oil tank. Hydraulic system maintenance: regular replacement of hydraulic oil, cleaning hydraulic filter. Cooling system maintenance: clean the radiator, and check the coolant level. Transmission system maintenance: check the tightness of the transmission belt, and replace the worn transmission belt. Electrical system maintenance: check whether the line is firm...

Use and maintenance of drill bits

Use and maintenance of drill bits: 1. Choose a suitable drill bit:  Before using a drill bit, it is necessary to select the appropriate type and specification of drill bit based on drilling conditions and needs. 2. Installing the drill bit:  When installing the drill bit, it is necessary to ensure that the connection between the drill bit and the drill pipe is firm, and to correctly install the cutting teeth of the drill bit. 3. Maintain appropriate drilling speed and pressure during the drilling process:  Excessive drilling speed and pressure can lead to premature wear and damage of the drill bit, while too small can affect drilling efficiency. 4. Regular inspection and maintenance:  Regularly check the wear of the drill bit and replace severely worn components in a timely manner. At the same time, it is necessary to regularly clean and lubricate the drill bit to extend its service life. 5. Storage and preservation:  When storing and preserving drill bits, it i...
