Thepompu yamadzi yamagetsiImasintha kayendedwe ka coolant yozungulira malinga ndi momwe galimoto imagwirira ntchito ndikuzindikira kutentha kwa injini yagalimoto. Ndi gawo lofunikira kwambiri pamakina oziziritsira a galimoto yatsopano yamagetsi. Kuyesa magwiridwe antchito ndi gawo lofunikira kwambiri pakufufuza ndi kupanga ndi kupanga pampu yamadzi. Pakadali pano, kuyesa kwa pampu yamadzi yamagetsi yamagalimoto Kafukufuku waukadaulo ndi chitukuko cha zida sizinagwirizane ndi chitukuko cha mapampu amadzi amagetsi, ndipo kafukufuku wa njira zoyesera amayang'ana kwambiri pa mapampu amadzi achikhalidwe. Dongosolo laling'ono loyesera pampu yamadzi la NF limatha kuyeza magawo a magwiridwe antchito monga kuyenda kwa pampu, kukweza, ndi kugwira ntchito bwino kwa shaft kutentha kwa chipinda, ndikuzindikira deta yoyesera. Kusonkhanitsa mwachangu kwa kulimba kwa mpweya wa pampu yamadzi. Benchi loyesera mpweya wa pampu yamadzi losavuta kupanga limagwiritsa ntchito kupanikizika kosiyana kuti lizindikire kulimba kwa mpweya wa pampu yamadzi. Dongosolo loyesera lapampu yamadzi limapangidwa pogwiritsa ntchito mabwalo ophatikizidwa ndi analog.
Malinga ndi muyezo wa makampani QC/T288.2-2001 ndi JB/T8126.9-2017 ndi zofunikira zina zokhudzana ndi mfundo, kuwunika mtundu wa pampu yamadzi yozizira kumaphatikizapo mayeso a magwiridwe antchito, mayeso a cavitation, ndi zina zotero. Kudzera mu kuyesa kuchuluka kwa madzi, magetsi, ndi mphamvu yamagetsi, kuthamanga kwa madzi olowera ndi otuluka, kuwerengera mutu, mphamvu, magwiridwe antchito, NPSH ndi magawo ena a magwiridwe antchito, malizitsani kujambula kwa curve ya flow-head, flow-power, flow-efficiency, flow-NPSH performance curve ya mapampu amagetsi.
Mosiyana ndi pampu yamadzi yozizira yamakina, liwiro lapompu yamadzi yamagetsiimayendetsedwa ndi makina ake ophatikizika, ndipo mphamvu yamagetsi ndi chizindikiro chowongolera chomwe chaperekedwacho chingapangitse mota yamkati yopanda burashi ya DC kugwira ntchito pa liwiro lofanana. Njira yachikhalidwe yoyesera mphamvu ya injini ndi liwiro kuti iwerenge mphamvu yolowera ya pampu yamadzi si yoyenera pamagetsi. Pa kuyesa pampu yamadzi, ili ndi mphamvu yokonzedwa kuti iwerenge mphamvu yamagetsi pamene pampu yamadzi ikugwira ntchito, kuwerengera mphamvu yolowera ya mota kudzera mu mphamvu yamagetsi ndi mphamvu yamagetsi, kenako kuchulukitsa ndi mphamvu yogwira ntchito kuti ikhale mphamvu yolowera ya pampu yamadzi yamagetsi.
Magawo akuluakulu aukadaulo a dongosolo loyesera: mulingo woyezera kuyenda kwa madzi 0~500L/min, kulondola kwa muyeso ±0.2%FS; mulingo woyezera kuthamanga kwa kulowa ndi kutuluka -100~200kPa, kulondola kwa muyeso ±0.1%FS; mulingo woyezera wamakono 0~30A, kulondola kwa muyeso ±0.1 %FS; mulingo woperekera magetsi wamagetsi wokonzedwa 0~24V, kulondola kwa kuwerenga ±0.1%FS, mulingo wamagetsi 0~200W; mulingo woyezera kutentha -20~100℃, kulondola kwa muyeso ±0.2%FS, mulingo wolamulira kutentha 0~80℃, kulondola kwa muyeso ±2°C.
Ndondomeko yoyesera magwiridwe antchito onse
Malinga ndi miyezo yoyesera yamakampani, mayeso onse ogwira ntchito a mapampu amadzi amafuna kuti mkati mwa 40% ~ 120% ya liwiro lovomerezeka la pampu, malo osachepera 8 ogwirira ntchito akhazikitsidwe mofanana malinga ndi kuchuluka kwa madzi omwe amadutsa mupaipi yoyesera. Kudzera mu PID control, Sinthani kutseguka kwa valavu yolumikizirana yotulutsira madzi kuti ikhazikitse kuyenda pamalo oyendera. Sensa imayang'anira kuthamanga kwa kulowa ndi kutuluka, kutentha, kuchuluka kwa madzi omwe amatuluka mupaipi yoyesera madzi yamagetsi nthawi yeniyeni, komanso kuchuluka kwa magetsi ogwirira ntchito ndi mphamvu zamagetsi za pampu yamagetsi. Pamene flowmeter imayang'anira kuti kuyenda mupaipi kuli kokhazikika Patapita nthawi, lembani kuchuluka kwa madzi omwe amatuluka mupaipi. Podziwa kukula kwa payipi, kusiyana kwa kutalika pakati pa kulowa ndi kutuluka, magawo a kuchuluka kwa madzi ndi kuthamanga kwa mphamvu yokoka, werengerani ma curve a flow-head, mphamvu ya flow, ndi flow-efficiency currents a pampu yamagetsi yamagetsi pa liwiro lovomerezeka ｡
