DL vertical multistage centrifugal pump

■ DL vertical multistage centrifugal pump Product Overview: DL vertical multistage centrifugal pump (low speed n = 1450r / min) is the resistance in the valve according to the actual needs and the Country Fire Authority high-rise building water supply market of GB 6245-1998 "fire pump performance requirements and test methods" is a new standard developed centrifugal pumps. Centrifugal pump for conveying hard particles and the physical and chemical properties similar to water media's use. Flow rate in the range of 5 ~ 360m3 / h, head range of 22 ~ 300m, supporting a power range of 1.5 ~ 220KW, and diameter range φ40 ~ φ200m. Export the same pump can be set from 1 to 5 outlets. ■ DL vertical multistage centrifugal pump Model significance: ■ DL vertical multistage centrifugal pump Features: 1. Compact DL vertical multistage centrifugal pump structure, small size, beautiful appearance, its vertical structure decided to install small footprint, its center of gravity coincides with the pump foot center, thereby enhancing operational stability and life of the pump. 2. DL vertical multistage centrifugal pump suction population and outlet are horizontally, simplifying the piping connections. 3. According to need, suction and discharge port of the population can be mounted in the same direction or 90 °, 180 °, 270 ° in several different directions to meet different connection situations. 4. DL vertical multistage centrifugal pump head can be adjusted according to needs and progression combine cutting impeller diameter to be met without changing the installation footprint, which is the other pumps do not have. 5. Motor plus rain cover, the pump can be placed outdoors, cancel pumping stations, saving construction costs. 6. DL vertical multistage centrifugal pump rotor has a smaller deflection, and the choice of a 4-pole motor, therefore smooth running, small vibration, low noise, and long service life. ■ DL vertical multistage centrifugal pump structure: No. Name material or model number or model name material 1 Motor Y series (V5) 4-pole 12 water segment HT200 2 coupling sleeve balance HT200 13 HT200 3 elastic rubber block 14 balance Drum HT200 4 bearing gland HT200 15 last stage vanes HT200 5 bearings and mid-cap 4516 HT200 6 bearing box HT200 17 vanes HT200 7 180 series bearing 18 impeller HT200 8 retaining cover 4519 water segment asbestos gland HT200 HT200 9 20 45 10 asbestos under sleeve bearing copper alloy 11 21 next stuffing body HT200 22 axis 45,2Cr13
