VI Vertical Multistage Centrifugal Pump
QDL/QDLF is a kind of vertica non-self priming multistage .Centrifugal pump, which is driven by a standard electric motor. The motor output shaft directly connects with the pump Shaft through a coupling. The pressure-resistant cylinder and flow passage components are fixed between pump head and in-located at the pump bottom at the same plane. This kind of pump can be equipped with an intelligent protector to effectively prevent it from dry-running, out-of-phase and overload

The following figure shows the limitation of pressure and temperature, which shall be kept within the region as shown in the figure.
limitation of pressure and temperature
X Performance curve
Following conditions are suitable for the performance curves shown bellow
All the performance curves are based on the measured values of a motor 3 80~415V at a constant speed of 2900 rpm.
Curve tolerance in conformity with ISO9906,appendix A.
Measurement is done with 20 air-free water, kater, kinematics viscosity of 1mm2/s.
The operation of pump shall refer to the performance region indicated by the thickened curve to prevent overheating due to too small flow rate or overload of motor due to too large flow rate.
XI NPSH Minimum inlet pressure NPSH
In case that the pressure in pump is lower than the stem pressure used to convey liquid, the capitations will occur. To avoid cavitations, a minimum pressure at the inlet side of the pump shall be guaranteed. The Maximum suction stroke can be calculated with following formula: H=Pb 0.2-NPSH-Hf-Hv-Hs
Pb=atmosphere pressure [bar]
(can be set as 1bar)
In a closed system, Pb means system pressure[bar]
NPSH=Net positive suction head[m]
(It can be read out from the point of possible max, flow rate shown on NPSH curve)
Hf=Pipeline loss at the [m]
Hv=Steam pressure[m]
Hs=Safety margin=Minimum 0.5m delivery head
If the calculated result H is positive, the pump may run under the max. Suction stroke H.
In case the calculated result H is negative, a delivery head of min. Inlet pressure is necessary
XII Operation in parallel
Connecting several pumps in parallel running will benefit much more than running a single large pump. Applicable to different working states necessary in a variable flow system. Increasing the possibility of water supply when the pump is in failure. Because in case of pump failure, only part of the system flow is effected.
Check and ensure that the pump is not at cavitations state.
Two pump or more can be connected in parallel running if necessary.
