1. Baleka iBEP:

Ukusebenza ngaphandle kwendawo ye-BEP yimbangela eqhelekileyo yokungaphumeleli kwe-shaft shaft. Ukusebenza kude ne-BEP kunokuvelisa amandla amaninzi emitha. Ukuphambuka kweshaft ngenxa yamandla eradial kudala amandla okugoba, okuya kwenzeka kabini ngokujikeleza kweshaft yepompo. Oku kugoba kunokuvelisa ukudinwa ukugoba kweshaft. Uninzi lwee-shafts zepompo zinokubamba inani elikhulu lemijikelezo ukuba ubungakanani bokuphambuka buphantsi ngokwaneleyo.

2. Ishafu yempompo egobileyo:

Ingxaki ye-axis egobileyo ilandela ingqiqo efanayo ne-axis ejikiweyo echazwe ngasentla. Thenga iimpompo kunye neeshafti ezishiyekileyo kubavelisi bemigangatho ephezulu/izinto ezicacileyo. Uninzi lokunyamezelana kwi-pump shafts kuluhlu lwe-0.001 ukuya kwi-0.002 intshi.

3. I-impeller okanye i-rotor engalinganiyo:

I-impeller engalinganiyo iya kuvelisa "i-shaft churning" xa isebenza. Isiphumo siyafana nokugoba kwe-shaft kunye / okanye ukuphambuka, kunye ne-shaft yepompo ye impompo yeinjini yomoya enzulu kakuhle iyakuhlangabezana neemfuno nokuba impompo imisiwe ukuze ihlolwe. Kunokuthiwa ukulinganisa i-impeller kubaluleke kakhulu kwiimpompo zesantya esisezantsi njengeempompo zesantya esiphezulu.

4. Iimpawu zolwelo:

Ngokufuthi imibuzo emalunga neempawu zolwelo ibandakanya ukuyila impompo yolwelo olusezantsi lwe-viscosity kodwa imelane nolwelo oluphezulu lwe-viscosity. Umzekelo olula uya kuba yimpompo ekhethiweyo ukumpompa iNombolo ye-4 ye-oyile ye-fuel kwi-35 ° C kwaye isetyenziswe ukumpompa i-oyile ye-fuel kwi-0 ° C (umlinganiselo oqikelelweyo yi-235Cst). Ukonyuka kobunzima obuthile bolwelo olumponthiweyo kunokubangela iingxaki ezifanayo.

Kwakhona qaphela ukuba i-corrosion inokunciphisa kakhulu amandla okukhathala kwe-pump shaft material.

5. Ukusebenza kwesantya esiguquguqukayo:

I-torque kunye nesantya zihambelana ngokungafaniyo. Njengoko impompo iyancipha, i-torque ye-pump shaft iyanda. Ngokomzekelo, ipompo ye-hp ye-100 idinga i-torque ephindwe kabini kwi-875 rpm njengepompo ye-100 hp kwi-1,750 rpm. Ukongeza kwinqanaba eliphezulu le-brake horsepower (BHP) kwi-shaft yonke, umsebenzisi kufuneka ahlolisise umda ovumelekileyo we-BHP nge-100 rpm utshintsho kwi-pump application.

6. Ukusetyenziswa kakubi: Ukungahoyi izikhokelo zomenzi kuya kukhokelela kwiingxaki ze-shaft zepompo.

Uninzi lweeshafti zempompo zinemiba ethobayo ukuba impompo iqhutywa yi-injini kunenjini yombane okanye i-injini yomphunga ngenxa ye-intermittent vs. torque eqhubekayo.

ukuba impompo yeinjini yomoya enzulu kakuhle ayiqhutywa ngokuthe ngqo nge-coupling, umz. ibhanti/ipuli, ityathanga/i-sprocket drive, ishafti yempompo inokonakaliswa kakhulu.

Iimpompo ezininzi zokuzilungisa ziyilelwe ukuba ziqhutywe ibhanti kwaye ngoko zineengxaki ezimbalwa ezingentla. Nangona kunjalo, nzulu kakuhle impompo yeinjini ethe nkqo yenziwe ngokuhambelana ne-ANSI B73.1 iinkcukacha azenzelwanga ukuba ziqhutywe ibhanti. Xa kuqhutywa ibhanti kusetyenziswa, awona mandla eehashe aphezulu avumelekileyo aya kuncitshiswa kakhulu.

7. Ulungelelwaniso:

Nokuba nokungalungelelani okuncinci phakathi kwempompo kunye nezixhobo zokuqhuba kunokubangela amaxesha okugoba. Ngokuqhelekileyo, le ngxaki ibonakalisa ukungaphumeleli kokuthwala ngaphambi kokuba i-shaft yepompo iphuke.

8. Ukungcangcazela:

Ukushukuma okubangelwa iingxaki ngaphandle kokungahambi kakuhle kunye nokungalingani (umzekelo, i-cavitation, ukudlula i-blade frequency, njl.) kunokubangela uxinzelelo kwi-pump shaft.

9. Ufakelo olungachanekanga lwamalungu:

Ngokomzekelo, ukuba i-impeller kunye ne-coupling ayifakwanga ngokuchanekileyo kwi-shaft, ukulungelelaniswa okungalunganga kunokubangela i-creep. Ukunxiba kwezilwanyana ezirhubuluzayo kunokukhokelela ekungaphumeleli kokudinwa.

10. Isantya esingafanelekanga:

Isantya esiphezulu sempompo sisekelwe kwi-inertia ye-impeller kunye (ne-peripheral) umda wesantya sebhanti. Ngaphezu koko, ukongeza kumcimbi wokunyuka kwe-torque, kukho kwakhona ukuqwalaselwa kokusebenza kwesantya esisezantsi, njengale: ukulahlekelwa yimpembelelo yokutshatyalaliswa kwamanzi (i-Lomakin effect).
