  • 4. The average flow rate of the pipeline is too low, and the average flow rate of the pipeline is lower than the critical settlement deceleration, resulting in pipeline blockage and unable to transport slurry normally. Through the above examples, it can be seen that the selection of ZJ series slurry pump is more complicated, and if any link makes a mistake, it may lead to the mistake of the entire selection, causing irreparable losses to users, and having an adverse impact on their reputation. Therefore, in the selection, we must pay attention to the values of several key coefficients and calculate them carefully to achieve accuracy, so that the ZJ series slurry pump can fully reflect its advantages in field application.

    A 20mm drill rod typically refers to a cylindrical tool made of high-strength steel, designed for use in drilling operations. Its 20mm diameter strikes a balance between robustness and manageability, allowing it to penetrate materials while maintaining sufficient structural integrity. The rod can be produced in various lengths, which can be tailored to the specific requirements of a drilling project. Additionally, many manufacturers offer drill rods with various coatings or treatments to enhance wear resistance and durability, making them suitable for use in harsh environments.
