  • 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.

    Post-processing of large castings, large foundry processing manufacturers can use liquid sandblasting to clean the oxide scale and residue on the surface of the casting, which can not only remove impurities, but also play a role in polishing and improving the surface finish of the casting; Use grinding wheels, abrasive cloths, sandpaper and other abrasives to remove impurities such as burrs, protrusions and oxide scales on the surface of steel castings, so that the surface is smooth. In addition, methods such as mechanical, electrochemical and chemical polishing can further improve the gloss and corrosion resistance of castings.

    Drilling equipment is essential in various sectors, including oil and gas, mining, construction, and environmental research. Each sector requires specialized machinery capable of performing specific tasks effectively. For instance, in the oil and gas industry, rotary drill rigs and downhole drilling tools are critical for accessing subterranean resources. In contrast, the mining sector demands heavy-duty equipment designed to penetrate solid rock and extract valuable minerals.
