50NWL 40WDL 50WDL 100NWL type sewage mud pump main purposes: 1,50NWL NL-type multi-purpose liquid pump is single stage single suction centrifugal pumps used in mining 3 m 4 m long rod pump, paper, printing and dyeing, environmental protection, graphite, mica, gold , ceramics, oil refining, petrochemical, chemical, farm, salt, iodine field, dyeing, wine, food, fertilizer, coking, processing plant, construction, marble factory, gold, mud, sand, mud, sewage pond, dirty fluid delivery suck a thick liquid, filling and sewage operations suspended substances, but also for mine drainage and fluid containing mud of. 2, if the high pressure pump pumps 100NWL 150NWL stainless steel pole, pole pumps with 3-inch gun, a hydraulic mechanized earthmoving machine, used for the formation of land, river and pond dredging, drilling and other small water conservancy excavation with the losing side, and the city's air defense projects, underground engineering. 3, the fish used as clear pond with water, oxygen and other pond. Vertical pole into the water sewage pump sewage pump fluid flow method selected two or more techniques pump outlet when sharing a pole pump, valves and check valves should be installed on each pump outlet. Single pump drainage may produce intrusion, should set up check. 75NWL 40WGL allowed to drain off and the pressure inside the building gravity drainage discharge merger. 1, when there is a displacement of adjustment, the maximum hourly flow rate can be selected life drainage. Within the fire elevator sump pump discharge flow is not less than 10L / s. After the drain pump head by lifting height, pipe loss calculation OK, and then add a certain freedom head. Freedom head should adopt 0.02 ~ 0.03MPa. Under vertical sump drain pump suction pipe and outlet flow rate of not less than 0.7m / s, and not more than 2.0m / s. Each life should drain sump unit set up a spare pump, 75NWL usually advised to run interactively inside public buildings. Basement, equipment room, garage floor drain washing or, in case of two and more than two drainage pumps do not pump equipment.
