What is the working principle of a water well drilling rig

 Working Principle of Water Well Drilling Rig

Water well drilling rigs gradually complete the drilling process by breaking up the formation with the drill bit and discharging the rock chips out of the well with the help of mud, airflow or gravity. Its core principle includes the following aspects:

1. Crushing the formation

Mechanical way:

The drill bit rotates or impacts under the power drive of the drilling rig, utilizing cutting or impact to break up the formation

2. Cleaning the bottom of the well

Mud circulation (positive or reverse circulation):

Positive circulation: Mud enters the bottom of the well from the drill pipe and carries the rock chips along the well wall back to the surface.

Reverse circulation: Mud flows from the well wall to the bottom of the well, and then brings the rock chips back to the surface through the drill pipe.

Pneumatic circulation: the rock chips are discharged from the borehole by the high-pressure airflow generated by the air compressor, which is commonly used in dry formations or deep wells.

3. Lifting and lowering of drilling tools

Using winches and wire ropes to raise or lower drill pipes and bits to adjust the drilling depth or change drilling tools.

4. Well wall stabilization

Mud wall protection: Formation of a mud film on the well wall by mud pressure to prevent the well wall from collapsing.

Casing: Casing is used to support the well wall in loose formations.

5. Power transmission

Power source: Diesel engine or electric motor provides power for the drilling rig, which drives the drill pipe to rotate or the drill bit to impact through the transmission system.

6. Rock cuttings discharge

Discharge device: The broken rock chips are transported to the surface by mud or air flow.

Sedimentation treatment: After the rock chips are separated through the sedimentation tank, the mud can be recycled.

Summarize: Water well drilling rigs gradually realize drilling operation to meet drilling demand through drilling bit crushing stratum, mud or airflow circulating to clean up the bottom of the well, and power transmission to control the operation of drilling tools.

How much does it cost to buy a slurry pump

  The price of slurry pumps can be affected by a variety of factors, so it is difficult to give an exact figure. Generally speaking, the price of slurry pumps will vary according to the following factors: Factors affecting the price of slurry pumps Pump type and specifications: flow, head, caliber, material and other parameters are different, the price will also have a big difference. Pump material: slurry pump contact medium corrosive different, the material selected is different, thus affecting the price. Common materials are cast iron, stainless steel, wear-resistant alloy. Pump brand: different brands of pumps, its technical level, quality, after-sales service and so on there are differences, the price will naturally be different. Pump configuration: pump configuration, such as motor, control system, seals, etc., will also affect the price. Purchase Quantity: Bulk purchases are usually discounted to a certain extent. Market conditions: Fluctuations in the price of raw materials...

How to replace the impeller of a slurry pump

  The impeller of the slurry pump is a wearing part, which needs to be inspected and replaced periodically. The process of replacing the impeller is relatively complex and requires certain specialized knowledge and skills. The following are the steps for replacing the impeller of the slurry pump: 1. Preparation Shut down and disconnect the power:  Before any operation, be sure to cut off the power supply to ensure safety. Preparation tools:  ready wrenches, screwdrivers, gaskets, new impeller and so on. Drain:  Empty the pump. Protective measures:  Wear protective gloves, safety glasses and other protective equipment. 2. Disassembly Procedure DISASSEMBLY:  Disassemble the suction and discharge pipes connected to the pump. Remove pump cover:  Loosen the bolts securing the pump cover and carefully remove the cover. Remove the impeller:  Loosen the nuts secure the impeller with a suitable tool and remove the impeller. 3. Install the new impeller Insp...
