Optimization Parameters

The article presents a refining method for a two-stage screw centrifugal pump by the joint usage of mathematical optimization software IOSO, meshing complex NUMECA and CFD software ANSYS CFX. The pump main parameters: high-pressure stage rotor speed was 13300 rpm; low-pressure rotor speed was 3617 rpm by gearbox; inlet total pressure was 0.4 MPa; outlet mass flow was 132.6 kg/s at the nominal mode. This article describes the process of simplifying the calculation model for the optimization. The parameters of camber lines of the low-pressure impeller, transition duct, and high-pressure impeller blades for two sections (hub and shroud) were chosen as optimization parameters. The blades of low-pressure impeller, transition duct and high-pressure impeller have changed during optimization. The optimization goal was the increase of the pump efficiency with preservation or slight increase in the pressure head. The efficiency was increased by 3%.

According to the studying on the force analysis of floating ring of centrifugal pump, the paper think that floating ring stress will change with the change of centrifugal pump’ s condition. Using fluent software, the floating ring seal was simulated and analyzed. Results show that the liquid force acted on the floating ring is nonuniform and asymmetrical as wedging effect, and that section maximum pressure is not lies in the smallest clearance place, but in the wedge area where liquid flows to the minimum clearance, because the effect of Leak resistance is better in high pressure than low pressure. The leakage decreases and liquid resistance increases with the increases of RPM. The leakage increases with the increases of differential pressure in sealing ring sides and eccentricity. Pressure distribution within the seal clearance is not uniform with the increases of eccentricity.

Reverse Osmosis Desalination

According to the energy consumption status and characteristics of high pressure pump in Seawater Reverse Osmosis desalination unit of 2500m3/d and 5000 m3/d capacity, reasonable types of high pressure pump were chosen. Research on improving the efficiency of the two types of high pressure pump was made. Without affecting the pump reliability, structural optimization was made centering a round improving the energy efficiency or making efforts to improve energy efficiency. CFD technology was adopted in the fluid end design of the reciprocating pump and high efficiency hydraulic model chosen of the multistage centrifugal pump. For multistage centrifugal pump, several hydraulic models with good hydraulic characteristics were chosen. Numerical method was used in the performance prediction and modeling. Test results show that the optimized reciprocating pump efficiency reaches 93.36% and the multistage centrifugal pump efficiency reaches 80%. This research provides theoretical guidance for reducing energy consumption of Seawater Reverse Osmosis (SWRO) and improving the efficiency of high pressure pumps.
