I. Nneɛma titiriw a ɛwɔ slurry pumps mu .
1. Nhyɛso a emu yɛ den ne nea ɛko tia nsɛe .
Wɔtaa de chromium aduru a ɛkorɔn (Cr26~Cr30) anaasɛ rɔba a wɔde hyɛ mu, a HRC60 anaa nea ɛboro saa no yɛ den, ne nea ɛyɛ den a ɛko tia 5~8 mpɛn a ɛyɛ dade a ɛyɛ mmerɛw (ka "slurry pipeline transportation design manual" no mpɛn pii na ɛyɛ slurry pumps (te sɛ impellers ne guard plates) no. Sɛ nhwɛso no, 150ZJ slurry pump a wɔde di dwuma wɔ mine mu no wɔ nkwa nna a ɛboro nnɔnhwerew 8000 bere a wɔde slurry a 30% quartz anhwea wom no kɔ.
2. Nsu a ɛsen ne ti a ɛkorɔn ho nhyehyɛe .
Sɛ wode wide flow impellers ne heavy-DUTY bearing supports di dwuma a, single-afiri a ɛsen no betumi adu 5000m3/h (te sɛ 350ZGB model), na ti no kata mita 20 ~ 150 so, a ɛfata ma bere tenten-akyirikyiri akwantu.
3. Nsɔano a ɛyɛ mmerɛw .
Sɛnea medium no su te no, wobetumi apaw impeller seal aboafo, mfiri nsɔano anaa packing seal. Sɛ nhwɛso no, bere a wode pH refa acid slurry adi dwuma no .<3, it is recommended to use a double-end mechanical seal + flushing water system.
II. Application scenarios a wɔtaa de di dwuma ne nsɛntitiriw a wɔpaw .
1. Nnwuma a wotu fagude wom .
- tailings Transportation: Ɛsɛ sɛ wɔde particle size (mpɛn pii no ɛsua anaa ɛne 50mm yɛ pɛ) ne concentration (20%~60%) hyia. Kɔbere a wotu ho adwuma bi de 200ZJ-I-A50 model no di dwuma de di tailings a ɛwɔ density a ɛyɛ 1.8T/m3, a afe afe adwumayɛ mu mmɔdenbɔ yɛ 92%.
- Cyclone feeding: Ɛhia sɛ pɔmpɛ nipadua no soa nhyɛsoɔ a ɛboro anaa ɛne 1.6MPa yɛ pɛ. Asɛm no kyerɛ sɛ 100ZJL pɔmpɛ no a wɔde di dwuma no betumi atew ahoɔden a wɔde di dwuma no so 15%.
2. Tumi a ɛma obi tumi yɛ adwuma .
- limestone slurry circulation: CL- corrosion resistance hia (concentration taa du 20000ppm). Wɔkamfo pɔmpɛ a wɔde rɔba ayɛ te sɛ DT series no kyerɛ, na wɔhwɛ mfomso a ɛfa nsu a ɛsen ho no so wɔ ±3% mu.
3. Asubɔnten no kwan a ɛkɔ fam .
- Anhwea a ɛwɔ mu tebea a ɛkorɔn: Fa slurry pump a ɛtumi fa nsuo ase (te sɛ WQ type), a ne kɛseɛ yɛ 80mm, na ɛhia sɛ wɔsiesie ti a ɛyera no denam factor 1.05 so wɔ 10% nkɔanim biara a ɛba wɔ anhwea a ɛwɔ mu no mu (sɛnea GB/T 5656-2008 kyerɛ no).
iii. Mfiridwuma mu Nkɔso Nkɔso .

Slurry pump foforo no de IoT sensor ahorow no bom de hwɛ bearing hyew (accuracy ±1℃) ne vibration value ( a ennu anaasɛ ɛne 4.5mm/s yɛ pɛ) wɔ bere ankasa mu.

2. Ahoɔden a wɔkora so yiye .
Ɛnam CFD simulation so ma flow channel nhyehyɛɛ no tu mpɔn no, wɔama nhwɛsoɔ pɔtee bi adwumayɛ akɔ soro akɔduru 78% (bɛyɛ 65% ama atetesɛm pɔmpɛ), na afe afe anyinam ahoɔden a wɔkora so no boro kWh 200,000 (Data Source: China General Machinery Industry Association 2023 Report).
