Pearldrill PDC Bits and Pumps

  Positive circulation and reverse circulation drilling rigs have significant differences in the drilling process, mainly reflected in the direction of mud flow and slagging method. Positive Circulation Drilling Rig Working Principle: In a positive circulation drilling rig, mud is pumped from the mud pool by a mud pump and transported downward to the drill bit through the inner cavity of the drill pipe. When drilling, the drill bit crushes the surrounding soil and rock to form drill slag, which rises with the mud along the hole wall and eventually overflows from the hole into the sedimentation tank for sedimentation treatment. Characteristics: Weak capacity of slag discharge: as the mud flows upward from below, the slag discharge effect is not as good as reverse circulation in some cases. Simple process: relatively easy to operate, suitable for sand layer and other geological conditions that are not easy to collapse. Lower cost: equipment and operation costs are relatively cheap Re...

  Behind the price difference of sand suction pumps lie many influencing factors. These factors directly determine the pump's performance, longevity, and ultimately cost-effectiveness. Let's analyze them in detail below: 1. Material differences Cast iron vs. alloy steel:  cast iron pumps are relatively cheap, but less wear-resistant, suitable for occasions with less sediment content. Alloy steel pumps, especially high chromium alloy steel pumps, excellent wear resistance, suitable for high concentration of sediment extraction, but the price is higher. Seal material:  The quality of seal material directly affects the life and reliability of the pump. High-quality mechanical seals and packing can extend the service life of the pump, but the cost will increase accordingly. 2. Process differences Casting technology:  Precision casting of pump parts with high surface finish and good fit, but at a higher cost. Processing accuracy:  high precision machining process can...

  Media Characteristics Sediment concentration: The higher the concentration of sediment, the higher the requirement for wear resistance of the pump. Particle size: The coarser the particles, the higher the wear resistance requirement for the overflow parts, and also has an impact on the pump's flow capacity. Medium acidity and alkalinity and temperature: these factors will affect the choice of pump material. Working conditions Lift: the lift is the pump will lift the height of the liquid, directly affecting the choice of pump. Flow: Flow refers to the volume of liquid pumped per unit of time, according to the actual needs of the choice. Working pressure: working pressure is too high, will have an impact on the pump seals and materials. Working time: The length of continuous working time will affect the selection of pump type and material. Pump performance Abrasion resistance: Sand suction pumps should have good abrasion resistance of the overflow parts to extend the service life. ...

  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...

  China's standards for pump machine manufacturing are refined and the design is high-end, in line with high-end instrumentation processes. Why do you say so? The standard system is perfect:  China has established a relatively perfect pump machine manufacturing standard system, covering the design, manufacturing, testing, and other aspects. Enterprise level varies:  due to fierce market competition, enterprise scale, and technology level vary greatly, resulting in uneven product quality. Insufficient independent innovation capacity:  some core technologies and high-end products are still dependent on imports, and independent innovation capacity needs to be improved. Environmental protection requirements continue to improve:  the state of the pump machine efficiency, noise and other aspects of the requirements are becoming more and more stringent, promoting technological progress in the industry. China's pump manufacturing advantages: Large industrial scale:...

There are differences in materials, processes, performance, durability, etc., which directly affect their prices. Factors influencing the price of slurry pumps Material: Wear-resistant materials:  High-end slurry pumps are made of high-chromium alloys, wear-resistant ceramics and other highly wear-resistant materials . But   t he low-end pumps are usually made of ordinary cast iron or carbon steel, which has poor wear resistance. Corrosion-resistant materials:  If the conveying medium is corrosive, corrosion-resistant alloy materials are required, which also increases costs. Manufacturing Process: Precision casting:  High-end pumps use precision casting process to ensure the dimensional accuracy and surface finish of key components such as impellers and pump bodies, and improve the efficiency and life of the pump. Welding process:  The quality of the welding process directly affects the strength and sealing performance of the pump. Performance Parameters: Flow a...

  PDC drill bits have high drilling efficiency and low loss, the following are the places to pay attention to PDC drill bits: 1. Match the specification of the drill bit with the formation Bit diameter:  It should be matched with the drilling diameter, too big or too small will affect the drilling efficiency and bit life. Number and shape of cutter flanks:  Choose the appropriate number and shape of cutter flanks according to the hardness and lithology of the formation. For hard strata, it is better to choose the drill bit with more cutter wings and sharp shape; for soft strata, it is better to choose the drill bit with fewer cutter wings and rounded shape. Thickness of diamond layer:  The thickness of the diamond layer directly affects the wear resistance of the drill bit, the higher the hardness of the formation, the thicker the diamond layer should be. 2. Drill Bit Quality Brand and Manufacturer:  Choose a drill bit made by a famous brand or a manufacturer wi...
