Characteristic Selection and Application of NL Vertical Sewage Pump
NL Vertical Sewage Pump Characteristics Selection and Application NL Sewage Pump Structure Features: NL vertical mud pump is a single-stage single-suction vertical centrifugal pump, the fluid flows along the axis of the pump shaft in the direction of 70 ℃, The main components are volute, impeller, pump base, pump housing, support tube, motor base, motor and other components. Volute, pump seat, motor seat, impeller nut is cast iron, corrosion resistance, corrosion resistance is better, the processing technology is convenient. Impeller is a single string of three curved leaves, the choice of semi-enclosed impeller, and the use of malleable iron, so high strength, corrosion resistance; processing convenience, good sex, high efficiency. In order to reduce weight and reduce the amount of turning, the shaft is made of high-quality carbon steel cold-drawn Park Steel. The pump seat is equipped with four skeleton oil seals and bushings to prevent shaft wear and prolong the service life of the shaft. The pump can be vertical or inclined to use, small footprint, volute buried in the working medium to work, easy to start, do not bow I water, the direction of rotation should be clockwise from the motor to see is the work. Switchboard length with a variety of specifications, so that the use of units according to their own use according to local conditions.

Available municipal, infrastructure, chemical, printing and dyeing, pharmaceutical, shipbuilding, foundry, food and other fluid pump thick, dirty liquid, paste body, the flow of sand and mud flows in rivers, etc., can also line up with mine containing mud, small Gravel fluid. If the high-pressure water loose fitting, consisting of hydraulic machinery earth work unit, also can be used for excavation and transportation in the city's air defense and underground project in the land of Small Water formation, dredging rivers and pools, drilling and so on.
