Kodi mfundo yogwiritsira ntchito pampu yodzipangira-priming ndi iti?

Pali mitundu yambiri yaGK-CB High-Pressure Self-Priming Pumpmapangidwe, pakati pawo, mfundo yogwirira ntchito ya pampu yodzipangira yokha yosakanikirana ndi kudzaza chipolopolo cha mpope ndi madzi musanayambe kupopera (kapena pali madzi mu chipolopolo cha mpope).Pambuyo poyambitsa, choyikapochi chimayenda mothamanga kwambiri kuti madzi a mumsewu apite ku volute.Panthawiyi, vacuum imapangidwa polowera kuti mutsegule valve yolowera.Mpweya wa chitoliro choyamwa umalowa mu mpope ndipo umafika m'mphepete mwa kunja kudzera mu njira ya impeller.

Kumbali ina, madzi otulutsidwa mu chipinda cholekanitsa cha gasi-madzi ndi chopondereza amabwerera kumphepete kwakunja kwa chopondera kudzera kumabowo obwerera kumanzere ndi kumanja.Pansi pa mphamvu ya mphamvu yokoka ndi mphamvu yokoka, madziwo anabwerera kuchokera kudzenje lakumanzere akuwombera mumtsempha wamagetsi ndipo amathyoledwa ndi choyikapocho.Pambuyo pa kusakaniza ndi mpweya kuchokera ku chitoliro choyamwa, madzi amaponyedwa ku volute ndikuyenda mozungulira.Kenako imalumikizana ndi madzi kuchokera ku dzenje lakumanja lamadzi ndikuyenderera mozungulira pozungulira.

Monga madzi amakhudza mosalekeza cascade mu volute ndipo nthawi zonse wosweka ndi impeller, izo mwamphamvu wothira mpweya kupanga mpweya kusakaniza madzi, ndi kuyenda mosalekeza kumayambitsa mpweya-madzi sangathe kulekana.Chosakanizacho chimachotsedwa ndi lilime potulukira volute ndikulowa m'chipinda cholekanitsa pamodzi ndi chubu lalifupi.Mpweya mu chipinda cholekanitsa umalekanitsidwa ndikutulutsidwa ndi chitoliro chotulutsira madzi, pamene madzi akuyendabe kumphepete kwa kunja kwa chopondera kudzera kumabowo obwerera kumanzere ndi kumanja ndikusakanikirana ndi mpweya mu chitoliro choyamwa.Mwanjira imeneyi, mpweya wa mupaipi woyamwa umatha pang’onopang’ono, ndipo madziwo amalowa mu mpope kuti amalize kudzipangira yekha. 

Mfundo yogwiritsira ntchito pampu yamkati yosakanikirana yodzipangira yokha ndi yofanana ndi ya pampu yosakanikirana yodzipangira yokha.Kusiyanitsa ndiko kuti madzi obwererawo samayenda kumphepete kwa kunja kwa choyikapo, koma kulowera kwa choyikapo.Pamene kusanganikirana kwamkati pampu yamadzimadzi kumayambika, valavu ya reflux kutsogolo ndi pansi pa choyikapo iyenera kutsegulidwa kuti madzi mu mpope abwerere ku cholowera cholowera.Madziwo amasakanizidwa ndi mpweya wochokera ku chitoliro choyamwa pansi pa kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake.Apa mpweya umatulutsidwa ndipo madzi amabwerera ku cholowera cholowera kuchokera ku valve yobwerera.Bwerezani izi mpaka mpweya utatha ndipo madzi atengeka.

Kutalika kwapampu yodzipangira yokha kumakhudzana ndi zinthu monga chisindikizo cha kutsogolo kwa choyimitsa, kuchuluka kwa kusintha kwa mpope, ndi msinkhu wamadzimadzi a chipinda cholekanitsa.Chilolezo chaching'ono chosindikizira kutsogolo kwa choyikapo, ndiye kuti kutalika kwadzidzidzi kumakulirakulira, nthawi zambiri 0.3 ~ 0.5 mm;Pamene chilolezo chikuwonjezeka, mutu ndi mphamvu ya mpope idzachepa kupatula kutalika kwa kudzipangira.Kutalika kwa mpope kumawonjezeka ndi kuwonjezeka kwa liwiro la circumferential u2 la choponderetsa, koma pamene kutalika kwa zui kuli kwakukulu, chiwerengero cha zosinthika chimawonjezeka, koma kutalika kwa kudzipangira sikumawonjezeka. , panthawiyi, nthawi yodzipangira yokha imafupikitsidwa; 

Pamene chiwerengero cha zosinthika amachepetsa, kudzikonda priming kutalika amachepetsa.Pokhapokha kuti mikhalidwe ina imakhala yosasinthika, kutalika kwadzidzidzi kumawonjezekanso ndi kuwonjezeka kwa kutalika kwa kusungirako madzi (koma sikungathe kupitirira kutalika kwa kusungirako madzi kwa Zui kwa chipinda cholekanitsa).Pofuna kusakaniza bwino mpweya ndi madzi mu mpope wodzipangira yekha, masamba a choyikapo ayenera kukhala ochepa, kuti awonjezere phula la cascade;Ndi bwino kugwiritsa ntchito theka-open impeller (kapena impeller yokhala ndi tchanelo chokulirapo), chomwe chimakhala chosavuta kuti madzi akumbuyo alowetsedwe mozama mu choyikapo.

Mapampu ambiri odzipangira okha amafanana ndi injini yoyaka mkati ndikuyika pagalimoto yam'manja, yomwe ili yoyenera kumunda.
