The connection between the pump outer shell barrel bag and the liquid inlet pipe of the medium storage tank
The gas phase and liquid phase between the outer shell of the pump and the major storage tanks are controlled by valves in the pipeline layout to achieve independent operation.
Determination of the minimum liquid level H: H≥NPSHr(m)+pipeline loss (m) +0.5 (m); NPSHr is the NPSHr of the pump (0.5m),0.5m is the safety margin, generally H is greater than 1.5m
It is recommended to equip a flow meter to monitor the pump flow to avoid damage to the pump due to excessive flow operation.
If the medium contains impurities, it is recommended to install a basket filter (30 mesh or 40 mesh) in the liquid inlet pipeline
