First packing is the most common kind of seal, seal form by injecting water, constantly injected a certain water pressure inside the filler, a slurry pump to prevent leakage; not suitable for multi-level series for shaft seal expeller pumps, slurry pump wear, with packing seal. Simple packing seal structure, coal washing plant for pumps, easy maintenance, low price. Mechanical seals, dredging slurry pumps, generally require a relatively high sealing case. In particular, some chemicals, the food industry, not only requires sealing, and most are not allowed to add extra ingredients into the pump. The disadvantage is that the high cost, slurry, maintenance difficulties. Pump power usually means that the input power, that power the pump shaft reached the prime mover, it is also known as shaft power. With "NZ" represents. Effective slurry pumping energy per unit time pump out the kind referred obtain effective power of the pump, also known as the output power, with "Ne" represents the value determined by the equation Ne = QH Sm / 102 KW (1-7 ) Where: Q- pump flow m3 / SH- pump head m Sm- slurry density kg / m3 slurry pumps, 100D-B40, wear a single shell provided by the Shijiazhuang-Slurry Pump Co. faction. Slurry pumps, 100D-B40, wear single-hull Slurry Pump Co., Ltd. is Shijiazhuang-faction (www.shipaipump.com) this year introduced a new upgrade, the above picture is for reference only, please call or pictures on this page contact telephone number, to obtain the latest information, Contact: Manager Xu.
