  • 1.The selection of the pump is too large, and the flow and head are larger than the actual condition due to improper selection of the coefficient. This situation makes the pump in the operation process, cavitation phenomenon, resulting in premature damage of the pump flow parts under the combined action of cavitation and abrasion, in the case of serious cavitation, the pump will produce vibration and noise, and even lead to a sharp decline in the flow, head and efficiency of the pump can not run; In addition, the pump in the operation of large flow, will also cause motor overload, heat, serious will burn the motor.

    In the world of drilling operations, particularly in oil and gas exploration, the mud pump plays a crucial role. A mud pump is a vital piece of equipment that circulates drilling fluid (commonly referred to as mud) from the surface to the drill bit and back up to the surface. This fluid serves multiple functions it cools and lubricates the drill bit, removes cuttings from the wellbore, and maintains the necessary pressure to prevent the influx of formations fluids. Therefore, accurately calculating the performance of a mud pump is essential for efficiency and safety in drilling operations.

    In addition to its durability, the tungsten crusher model is designed for high efficiency. The crushing process often involves multiple stages, where larger pieces of ore are progressively reduced in size. Advanced technology such as hydraulic systems and automated controls can enhance throughput and improve the overall processing performance. These innovations not only save time but also reduce operational costs, making tungsten extraction more economically viable.

    It is important to know that the shape of the sand has an important impact on the surface finish of the casting. Circular sand is better than triangular sand because the triangular sand has a large gap, which is easy to lead to defects such as porosity; According to the nature of the casting, the sodium silicate quartz sand is selected to form a spalling layer, and combined with the characteristics of cooling and shrinkage of the casting, the surface defects are reduced. Coating a protective layer on the surface of large castings, such as the film on a coated sand mold, can improve the surface finish of the sand mold and reduce the surface defects of the casting.
