The NZJH series Heavy duty slurry pump is a high head slurry pump, which is mainly used for long-distance transportation of ore slurry, such as long-distance transportation of tailings. Due to the limitation of the peripheral speed of the rubber flow parts, the wet end materials (spare parts) of the NJZH slurry pump are made of metal without rubber parts. At present, the largest single stage head of NZJH series pumps can reach 100m.
2.1 Highest single-stage head up to 90m.
2.2 Options for different shaft seals
2.3 Disch. ID range available for (mm): 25, 50, 75, 100, 150
2.4 Low specific speed design ensures high head but long service life of wet ends.
FLUENT technology and EDEM technology are applied to fully optimize the impeller, cover plate liner and frame plate liner, etc. to obtain high efficiency and overcome local wear. The three-dimensional modeling adopts UG.
4.1 Model building and meshing
1. UG three-dimensional modeling, extracting and calculating water bodies;
2. The grid adopts hexahedral unstructured grid and is divided by ICEM software.
4.2 Model building and meshing
1, Calculation model
2, ANSYS-FLUENT calculation model software analysis;
MRF under multiple coordinates is used to solve the problem, and the turbulence model uses RNG;
3, The momentum equation and the continuity equation are solved simultaneously using the SIMPLEC algorithm.
