Pearldrill PDC Bits and Pumps

  These are the main differences between water well drill bits The principle of selecting the water well drilling bit: Stratigraphic conditions:  different stratigraphic hardness, degree of fragmentation, and other factors determine the selection of drill bit. Drilling purpose:  Different drilling purposes require different drill bits, such as coring drilling, directional drilling, and so on. D rilling   fluid   performance :  The performance of the drilling fluid affects bit wear and life. The  Rig Performance:  Factors such as the power and torque of the drilling rig will also influence the choice of the drill bit. Toothed Wheel Drill Bit： Features:  Good abrasion resistance, suitable for hard rock drilling. Classification:  According to the number of teeth, tooth type, material and so on are divided into various types. Scope of application:  Hard rock layer, medium hard rock layer, etc. PDC Drill Bit： Characteristi...

  Drilling pressure and drilling speed can be adjusted mainly by the following methods: The role of drilling pressure and drilling speed: Drilling pressure:  Drilling pressure refers to the axial force exerted on the drill bit, which is mainly used to break rocks. Too much drilling pressure will lead to premature wear and even fracture of the drill bit; too little drilling pressure will result in slow drilling speed and low efficiency. Rotation speed:  Rotation speed refers to the rotational speed of the drill bit, which is mainly used for cutting rock. Too high RPM will lead to overheating of the drill bit and shorten its service life; too low RPM will lead to slow drilling speed and low efficiency. Adjustment method of drilling pressure and speed: Starting drilling pressure and speed: Soft stratum:  Adopt the maximum displacement of the drilling pump, the rotational speed of about 100rpm, drilling pressure of about 1~2t. Adjust the drilling parameters after drillin...

  The water pump is the power equipment of the fluid transportation and distribution system. The adjustment of the water pump pressure is very important for the operation . There are a few  adaptations of the fluid transportation and distribution system: 1.  Add a frequency converter to adjust pump pressure: After the frequency converter is installed, the pressure is fed back to the frequency converter in real-time by using the pressure sensor installed in the water pump pipeline. After the frequency converter is reset to the required parameters, the electronic speed regulation function of the frequency converter is utilized, by changing the frequency of the motor to control the pump speed (pump water pressure and its speed are proportional), and then to achieve the regulation of pump pressure. 2. Set Pump Inlet and outlet control valves to adjust pump pressure: Increase Pump Inlet valve opening, system resistance increase, increase pressure, reduce pump inlet valve openi...

  1. Stratigraphic condition analysis Rock properties: Different rock properties have different requirements for  drill bits . Soft rock can use drill bits with large slag discharging capacity, while hard rock requires hard and wear-resistant drill bits. Strata with a high degree of fragmentation are prone to rock chips, which require drill bits with good slag discharge capacity. Stratigraphic and hydrological conditions: Groundwater level and water pressure will affect the selection of drilling fluids. Stratigraphy with high water content is prone to well wall collapse, which requires the selection of corrosion-resistant and scour-resistant drill bits. stratum complexity: Interlayers, faults, etc. in the stratum will increase the difficulty of drilling, and it is necessary to choose adaptable bits, for example, high geostress will easily lead to jamming of the drilling tools, and it is necessary to choose the bits with good rigidity and torsion resistance. 2. Drilling de...

  Common problems and solutions for the use of the drill bit of the   Dth   hammer   bit 1. Drill bit overheating Reason: Drilling pressure is too large, serious wear of the drill bit, and so on. Solution:Reducing the drilling pressure; increasing the amount of cooling water; Regularly checking the drill bit wear; Avoiding long time continuous operation and taking proper rest. 2. Drill bit clogging Reason: Rock chips are not discharged smoothly. Solution:You can clean the drill hole and remove the blockage, increase the air volume or water volume to improve the efficiency of slag discharge and Choose a suitable drill hole diameter. 3. Broken teeth of drill bit Reason: Poor quality of drill bit material, excessive drilling pressure, excessive impact force, hard objects in the rock layer, etc. Solution:You can choose a high quality drill bit; adjust the drilling pressure and impact force; Check the rock layer carefully; avoid drilling into the rock layer containing har...

Slurry pumps can encounter various issues that can affect their performance and longevity. Here are some common problems : Clogged nozzles: If the mortar mix is too thick, the aggregates can become lodged in the nozzle openings. and the particles that are too large can get stuck in the nozzle, restricting flow. Besides, If the mortar is allowed to harden inside the nozzle, it can become difficult to remove. Damaged seals: Seals can wear out gradually due to friction and exposure to abrasive materials, and if the seals is exposed to harsh chemicals. It also cause the leak. Broken gears or shafts: Excessive wear and tear, overloading, or foreign objects can cause mechanical components to break. For example,The pump has been in continuous use for an extended period, leading to wear and tear on the shaft. Exposure to moisture and chemicals in the mortar may also cause corrosion of the shaft, weakening its structure and functionality Bearing failure: O...

  The following points need to be noted when cleaning the water well drilling rig : 1. Safety first: Ensure that the equipment has been completely shut down and powered off during the cleaning process to prevent injury from accidental startup. 2. Choose appropriate cleaning supplies: Avoid using cleaning fluids that are corrosive to the equipment to avoid damaging parts. 3. Protect electrical components: Prevent cleaning fluid from entering the electrical system by using waterproof measures or paying special attention during cleaning. 4. Avoid excessive force: When wiping or rinsing, do not use excessive force to avoid damaging the surface or internal structure of the equipment. 5. Pay attention to the cleaning sequence: Generally, clean the exterior first, then clean the interior and key components. 6. Thorough drying: After cleaning, make sure that the equipment and components are completely dry to prevent rust or short-circuit and other problems. 7. Check seals: Check whether th...
