Introduction
Pressing bulging welding of corrosion resistant plate,it is a new generation centrifugal pmp initiated in China and may replace traditional IS pump and common corrosion proof pump.It features beautiful appearance,light and handy structure,high efficiency and energy saving,durable,corrsion proof ,low noise,etc.
Application
ZS Stainless steel horizontal single stage centrifugal pump is a sort of multifunction productwith wide application. it may transmit various mediums including water or industrial liquidand is suitable for different temperature, flow rate and range of pressure. lts typical applicationmainly includes the following aspects:
Water supply: filtration in water works , transportation and subarea water carriagepressurization of main duct;
Industrial pressurization: flow wetting system, cleaning system;
Transportation ofindustrial liquid: water supply of boiler, condensed system, cooling andair conditioning system, machine tool support, light acid and alkali transportation;
Water treatment: distilled water system or separator, swimming pool, etc.
Farmland irrigation, medicine and sanitation, etc.
Minimuminlet pressure NPSH
in case that the pressure in pump is lower than the steam pressure used to convey liquid, the cavitations willoccur. To avoid cavitations, a minimum pressure at the inlet side of the pump shall be guaranteed. TheMaximum suction stroke can be calculated with following formula:
H=Pbx10.2-NPSH-Hf-HV-Hs
Pb - Atmosphere pressure (bar) In a closed system, Pb means system pressure (barNPSH - Net positive suction head (m)
lt can be read from the point of Max flow rate shown on NPSH curve.Hf - Pipeline loss at the inlet (m)
It is in accordance with pipeline possible Max. FlowHv - steam pressure (m)
lt depends on liquid temperature and steam pressure valueHs - Safety margin (m)
Minimum 0.5m delivery head.
if the calculated result H is negative, the pump may run under the Max. Suction head H. in case thecalculated result H is negative, a delivery head of Min. nlet pressure is necessary.
1.The liquid temperature is comparatively higher;
2. Liquid flow exceeds rated value;
3.Suction head is comparatively large or inlet pipeline long;
4. System pressure is too low:
