Umzi-mveliso wethu waseNingbo wenze iipompo ze-vane ezingaphezu kwama-80,000 ngonyaka, kwaye ukhetho ngalunye luqala ngeefomyula ezimbini ezifanayo ezisetyenziswa liqela lethu lobunjineli imihla ngemihla.

Kwiziko lethu lemveliso laseNingbo, siqhuba imigca emi-6 yemveliso evelisa iipompo ze-vane ezingaphezu kwama-80,000 ngonyaka. Iqela lethu lobunjineli licubungule amawaka eenkcukacha zomthengi, kwaye ifomula yobungakanani engezantsi yindawo yokuqala kuyo yonke into esiyenzayo. Siyabelana ngayo apha ukuze abathengi bakwazi ukuziqinisekisa iimfuno zabo ngaphambi kokuba basithumelele i-RFQ.

Iifomula zokulinganisa: Izinga lokuhamba kunye nokubalwa kwamandla

Iqela lethu lobunjineli kwiziko lethu lemveliso elinemigca emi-6 yemveliso liqala rhoqoisikhokelo sokukhetha ipompo ye-hydraulicincoko ngeefomyula ezimbini. Ngenxa yokuba ezi fomula zimisela ukuhanjiswa kwepompo, uxinzelelo lokusebenza, kunye namandla emoto aza kuchaza indlela esebenza ngayo inkqubo yakho, ukuzibeka kwindawo efanelekileyo kwinqanaba leenkcazo kuthintela iimpazamo zokunciphisa ubungakanani kunye nokugqithisa esizibona rhoqo kwiinkcazo ezibonelelwa ngumthengi.

Ifomula yokuqala ibala ipompo efunekayoumgangatho wohambo:

Q (L/min) = V (cm³) × N (iistrowuku/min) ÷ 1000

Apho u-Q luhamba olufunekayo kwiilitha ngomzuzu, u-V luhamba ngesilinda okanye ngemoto kwiisentimitha zetyhubhu, kwaye u-N linani leemivumbo ngomzuzu (kwiisilinda) okanye isantya sokujikeleza kwi-RPM (kwiimoto ze-hydraulic). Kwiinkqubo ezinee-actuator ezininzi ezisebenza ngaxeshanye, hlanganisa iimfuno zokuhamba komntu ngamnye kwaye wongeze i-10 ukuya kwi-20 yepesenti yokulahleka kwenkqubo - ukuvuza kwangaphakathi kwiindawo zokuvula iivalvu, ukuhamba kwe-bypass kwiivalvu zokunciphisa uxinzelelo, kunye nokwandiswa kobushushu bolwelo olusebenzayo. Idatha yethu yemveliso evela kwimveliso yethu yepompo yonyaka engaphezu kwama-80,000 ibonisa ukuba ukungacacisi ilahleko kwinkqubo ngaphezulu kwe-15 yepesenti yimbangela eyintloko yezikhalazo zokusebenza kwentsimi ezimalunga nama-30 ekhulwini.

Ifomula yesibini ibala amandla okuqhuba afunekayo:

P (kW) = Q (L/min) × p (MPa) ÷ 60

Apho i-P ingamandla emoto afunekayo kwii-kilowatts, i-Q yisantya sokuhamba, kwaye i-p yingcinezelo yokusebenza kwii-megapascals. Le fomula ithatha ukusebenza kakuhle kwepompo nge-100% - enyanisweni, iipompo zethu ze-vane zifezekisa ukusebenza kakuhle kwe-volumetric ye-85 ukuya kwi-94% kuxhomekeke kuxinzelelo kunye nesantya, ngoko ke imfuneko yamandla yokwenyani yi-P eyahlulwe yi-efficiency factor. Kwipompo ehambisa i-80 L/min kwi-14 MPa kunye nokusebenza kakuhle kwe-90%: P = 80 × 14 ÷ 60 ÷ 0.90 = 20.7 kW. Iqela lethu lobunjineli libonelela ngee-curves zokusebenza kakuhle kwimodeli nganye yepompo, ezidwetshwe ngokuchasene noxinzelelo kunye nesantya, ukuze abathengi bakwazi ukubala imfuneko yamandla echanekileyo kwindawo yabo yokusebenza.
