1.Downhole drilling machine: When drilling a downhole gun hole with a aperture less than 150 mm, in addition to the application of a rock drill, it can also be used to drill a small diameter of 80 ~ 150 mm. When drilling a gun hole with a diameter of less than 70 mm in coal or softer mineral rock, it is generally used to drill or air drill, driven by a motor (or air motor) to drill the drill pipe, and the rock (coal) chips drilled out are discharged through the spiral groove on the drill pipe.

  • 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.
