Know the liquid itself has such physical properties, the dredging slurry pumps, let us analyze the pump cavitation causes: the pump impeller by rotating the liquid acting on the liquid energy (including kinetic and pressure energy) increase in the mutual the role of the process, the speed and pressure of the liquid is changed. Typically, centrifugal impeller is the pressure at the entrance to the lowest place expeller seal, slurry, through a reverse centrifugal force of the impeller, coal preparation plant pumps to prevent slurry leakage. The first stage pump positive pressure in the pump inlet pump outlet pressure is not greater than 10% of the value of a single-stage or multi-stage pump series pump can be used to pay the impeller shaft seal, slurry pump wear, without having to pay the impeller shaft seal sealing water, not diluted slurry, and good sealing effect and so on. Therefore, in the case of the slurry does not allow dilution, consider such a seal. Slurry pumps, 25D-A25, wear-resistant slurry pump supplied by Shijiazhuang-Pump Co., Ltd. faction. Slurry pumps, 25D-A25, wear-resistant slurry pump Pump Co., Ltd. Shijiazhuang Shi faction (www.shipaipump.com) this year introduced a new upgrade, the above picture is for reference only, please call the contact or pictures on this page phone, for the latest information, Contact: Manager Xu.
