1. NPSHA Yodabwitsa

Chofunikira kwambiri ndi NPSHA ya pampu yoyamwa kawiri. Ngati wosuta sakumvetsa bwino NPSHA, mpopeyo idzagwedezeka, kuchititsa kuwonongeka kwamtengo wapatali komanso nthawi yopuma.

2. Best Mwachangu Point

Kuthamangitsa mpope kuchoka ku Best Efficiency Point (BEP) ndilo vuto lachiwiri lomwe limakhudza mapampu awiri oyamwa. M'mapulogalamu ambiri, palibe chomwe chingachitike chifukwa cha zinthu zomwe mwiniwake sangathe kuzilamulira. Koma nthawi zonse pamakhala wina, kapena nthawi yoyenera, kuti aganizire kusintha chinachake mu dongosolo kuti pampu ya centrifugal igwire ntchito m'dera lomwe linapangidwira. Zosankha zothandiza zimaphatikizapo magwiridwe antchito osinthasintha, kusintha chowongolera, kukhazikitsa pampu yosiyana kapena mtundu wina wapope, ndi zina zambiri.

3. Kuvuta kwa Mapaipi: Silent Pump Killer

Zikuwoneka kuti ma ductwork nthawi zambiri samapangidwa, kuyikidwa kapena kuzikika moyenera, ndipo kukulitsa ndi kutsika kwamafuta sikuganiziridwa. Vuto la chitoliro ndilomwe likuganiziridwa kuti ndilomwe limayambitsa mavuto a kubereka ndi kusindikiza. Mwachitsanzo: titalangiza injiniya wapamalopo kuti achotse mabawuti a maziko a mpope, mpope wa tani 1.5 unakwezedwa ndi mapaipi makumi a millimita, chomwe ndi chitsanzo cha kupsyinjika kwakukulu kwa mapaipi.

Njira ina yoyang'anira ndikuyika chizindikiro choyimba pa kulumikizana mu ndege zopingasa ndi zoyima ndikumasula chitoliro choyamwa kapena chotulutsa. Ngati chizindikiro choyimba chikuwonetsa kuyenda kopitilira 0.05 mm, chitolirocho chimakhala chovuta kwambiri. Bwerezani masitepe omwe ali pamwambawa pa flange ina.

4. Yambani Kukonzekera

Mapampu oyamwa kawiri akukula kulikonse, kupatula mphamvu zotsika kavalo zolimba-zophatikizana, zokwera pamapampu otsetsereka, sikawirikawiri kufika mokonzeka kuyamba pamalo omaliza. Pampu si "pulagi ndi kusewera" ndipo wogwiritsa ntchito kumapeto ayenera kuwonjezera mafuta ku nyumba yonyamula katundu, kuika rotor ndi impeller chilolezo, kuyika chisindikizo cha makina, ndikuchita kafukufuku wozungulira pa galimotoyo asanakhazikitse cholumikizira.

5. Kuyanjanitsa

Kuyanjanitsa kwa pampu ndi kofunika kwambiri. Ziribe kanthu momwe pampu imayenderana ndi fakitale ya wopanga, kuyanjanitsa kumatha kutayika panthawi yomwe mpope imatumizidwa. Ngati mpopeyo ili pakati pa malo oikidwa, ikhoza kutayika pogwirizanitsa mapaipi.

6. Mulingo wa Mafuta ndi Ukhondo

Mafuta ambiri nthawi zambiri sakhala bwino. M'mabwalo a mpira okhala ndi makina opaka mafuta, mulingo wabwino kwambiri wamafuta ndi pomwe mafuta amalumikizana pansi pa mpira wapansi. Kuwonjezera mafuta owonjezera kumangowonjezera kukangana ndi kutentha. Kumbukirani izi: Chifukwa chachikulu chomwe chimalepheretsa kubereka ndikuwonongeka kwamafuta.

7. Ntchito Yowuma Pampu

Kumiza (kumiza kosavuta) kumatanthauzidwa ngati mtunda woyezedwa kuchokera pamwamba pa madzi mpaka pakati pa doko loyamwa. Chofunika kwambiri ndikumira kofunikira, komwe kumadziwikanso kuti kutsika kwambiri kapena kuzama kwambiri (SC).

SC ndiye mtunda woyima kuchokera pamadzimadzi kupita ku polowera pampu yoyamwa kawiri yofunikira kuti tipewe chipwirikiti chamadzimadzi ndi kuzungulira kwamadzimadzi. Chisokonezo chikhoza kuyambitsa mpweya wosafunikira ndi mpweya wina, zomwe zingayambitse kuwonongeka kwa mpope ndikuchepetsa ntchito ya mpope. Mapampu a centrifugal si ma compressor ndipo magwiridwe antchito amatha kukhudzidwa kwambiri popopera madzi a biphasic ndi/kapena multiphase (kulowetsedwa kwa mpweya ndi mpweya mumadzimadzi).

8. Kumvetsetsa Kupanikizika kwa Vacuum

Vacuum ndi nkhani yomwe imayambitsa chisokonezo. Powerengera NPSHA, kumvetsetsa bwino mutuwo ndikofunikira kwambiri. Kumbukirani, ngakhale mu vacuum, pali kuchuluka kwa (mtheradi) kupanikizika - ziribe kanthu kakang'ono bwanji. Sikuti ndi mphamvu ya mumlengalenga yomwe mumadziwa pogwira ntchito panyanja.

Mwachitsanzo, pakuwerengera kwa NPSHA kophatikiza mpweya wa mpweya, mutha kukumana ndi 28.42 mainchesi a mercury. Ngakhale mutakhala ndi vacuum yayikulu chonchi, pamakhala kupanikizika kokwanira kwa mainchesi 1.5 a mercury mumtsuko. Kuthamanga kwa 1.5 mainchesi a mercury kumatanthawuza kumutu wathunthu wa 1.71 mapazi.

Zoyambira: Vacuum yabwino ndi pafupifupi mainchesi 29.92 a mercury.

9. Valani mphete ndi Impeller Clearance

Kuvala pompo. Mipata ikavala ndikutseguka, imatha kukhala ndi zotsatira zoyipa papampu yoyamwa kawiri (kugwedezeka ndi mphamvu zopanda malire). kawirikawiri:

Kuchita bwino kwa pampu kudzachepetsa mfundo imodzi pa chikwi chimodzi cha inchi (0.001) pazovala zovomerezeka za mainchesi 0.005 mpaka 0.010 (kuchokera koyambirira).

Kuchita bwino kumayamba kuchepa pang'onopang'ono chilolezo chitatha mpaka 0.020 mpaka 0.030 mainchesi kuchokera pachilolezo choyambirira.

M'malo osachita bwino kwambiri, mpopeyo amangosokoneza madzimadzi, kuwononga mayendedwe ndi zosindikizira.

10. Suction Side Design

Mbali yoyamwa ndiyo mbali yofunika kwambiri ya mpope. Zamadzimadzi sizikhala ndi mphamvu zokhazikika. Chifukwa chake, chopopera chopopera sichingatalikitse ndikutulutsa madzimadzi mu mpope. Dongosolo loyamwa liyenera kupereka mphamvu zoperekera madziwo ku mpope. Mphamvu zimatha kubwera kuchokera ku mphamvu yokoka ndi gawo lokhazikika lamadzimadzi pamwamba pa mpope, chotengera choponderezedwa/chotengera (kapenanso pampu ina) kapena kungochokera kumpweya wa mumlengalenga.

Mavuto ambiri a pampu amapezeka kumbali yoyamwa ya mpope. Ganizirani za dongosolo lonselo ngati machitidwe atatu osiyana: njira yoyamwitsa, mpope wokha, ndi mbali yotulutsa. Ngati mbali yoyamwa ya dongosolo imapereka mphamvu zokwanira zamadzimadzi ku mpope, mpopeyo imathetsa mavuto ambiri omwe amapezeka kumbali yotulutsa dongosolo ngati asankhidwa molondola.

11. Zochitika ndi Maphunziro

Anthu omwe ali pamwamba pa ntchito iliyonse amayesetsanso kupititsa patsogolo chidziwitso chawo. Ngati mukudziwa momwe mungakwaniritsire zolinga zanu, pampu yanu idzayenda bwino komanso modalirika.
