1. Baleka i-BEP:

Ukusebenza ngaphandle kwendawo ye-BEP kuyimbangela evame kakhulu yokuhluleka kwe-pump shaft. Ukusebenza kude ne-BEP kungaveza amandla eradial amaningi. Ukuchezuka kwe-shaft ngenxa yamandla e-radial kudala amandla okugoba, azokwenzeka kabili ngokuzungezisa kwe-pump shaft. Lokhu kugoba kungadala ukukhathala okugoba ku-shaft. Iningi lama-pump shafts lingakwazi ukuphatha inani elikhulu lemijikelezo uma ubukhulu bokuphambuka buphansi ngokwanele.

2. Iphampu shaft egobile:

Inkinga ye-eksisi egobile ilandela ingqondo efanayo ne-eksisi echezukile echazwe ngenhla. Thenga amaphampu namashafti ayisipele kubakhiqizi bamazinga/imicijo ephezulu. Ukubekezelela okuningi kuma-pump shafts ku-0.001 kuya ku-0.002 intshi ububanzi.

3. I-impeller engalingani noma i-rotor:

I-impeller engalingani izokhiqiza "i-shaft churning" lapho isebenza. Umphumela uyafana nokugoba kwe-shaft kanye/noma ukuchezuka, kanye ne-pump shaft ye iphampu ye-turbine ejulile kahle izohlangabezana nezidingo ngisho noma iphampu imisiwe ukuze ihlolwe. Kungashiwo ukuthi ukulinganisa i-impeller kubaluleke kakhulu kumaphampu anesivinini esiphansi njengamaphampu anesivinini esikhulu.

4. Izinto eziwuketshezi:

Ngokuvamile imibuzo mayelana nezakhiwo zoketshezi ihlanganisa ukuklama iphampu yoketshezi olune-viscosity ephansi kodwa imelane noketshezi oluphakeme lwe-viscosity. Isibonelo esilula kungaba iphampu ekhethelwe ukumpompa uwoyela ongunombolo 4 ku-35°C bese isetshenziswa ukumpompa uwoyela kaphethiloli ku-0°C (umehluko olinganiselwe ngu-235Cst). Ukwenyuka kwamandla adonsela phansi athile oketshezi olumpontshwa kungabangela izinkinga ezifanayo.

Futhi qaphela ukuthi ukugqwala kunganciphisa kakhulu amandla okukhathala kwempahla ye-pump shaft.

5. Ukusebenza kwesivinini esiguquguqukayo:

I-torque nesivinini kuhambisana ngokuphambene. Njengoba ipompo iyancipha, i-torque ye-pump shaft iyanda. Isibonelo, iphampu engu-100 hp idinga i-torque ephindwe kabili ku-875 rpm njengepompo engu-100 hp ngo-1,750 rpm. Ngokungeziwe kumkhawulo omkhulu wamandla amabhuleki ehhashi (BHP) wawo wonke shaft, umsebenzisi kufanele ahlole umkhawulo ovumelekile we-BHP ngoshintsho lwe-100 rpm ekufakweni kwepompo.

6. Ukusebenzisa kabi: Ukungazinaki iziqondiso zomkhiqizi kuzoholela ezinkingeni ze-pump shaft.

Ama-pump shaft amaningi anezici ezinciphisayo uma iphampu ishayelwa injini kunenjini kagesi noma i-steam turbine ngenxa ye-intermittent vs. torque eqhubekayo.

Uma iphampu ye-turbine ejulile kahle ayishayelwa ngokuqondile nge-coupling, isb ibhande/i-pulley, iketango/i-sprocket drive, i-shaft yepompo ingase yehliswe kakhulu.

Amaphampu amaningi azenzelayo enzelwe ukuthi ashayelwe ngamabhande ngakho anezinkinga ezimbalwa kwezingenhla. Nokho, kahle kahle iphampu ye-turbine eqondile akhiwe ngokuhambisana ne-ANSI B73.1 imininingwane ayakhelwe ukuthi ishayelwe ibhande. Lapho kusetshenziswa ukushayelwa kwebhande, amandla aphezulu avunyelwe amahhashi azoncishiswa kakhulu.

7. Ukungaqondani kahle:

Ngisho nokungaqondani kahle okuncane phakathi kwepompo nemishini yokushayela kungabangela izikhathi zokugoba. Ngokuvamile, le nkinga izibonakalisa njengokuhluleka kokuthwala ngaphambi kokuba i-pump shaft iphule.

8. Ukudlidliza:

Ukudlidliza okubangelwa izinkinga ngaphandle kokungahambi kahle nokungalingani (isb, i-cavitation, imvamisa ye-blade edlulayo, njll.) kungabangela ukucindezeleka ku-pump shaft.

9. Ukufakwa okungalungile kwezingxenye:

Isibonelo, uma i-impeller ne-coupling ingafakiwe kahle ku-shaft, ukulingana okungalungile kungase kubangele ukukhahlela. Ukugqoka okunwabuzelayo kungaholela ekuhlulekeni kokukhathala.

10. Isivinini esingafanele:

Isivinini sephampu esiphezulu sisekelwe ku-impeller inertia kanye nomkhawulo wesivinini (i-peripheral) we-belt drive. Ngaphezu kwalokho, ngaphezu kodaba lokwenyuka kwe-torque, kukhona nokucatshangelwa kokusebenza ngesivinini esiphansi, njengokuthi: ukulahleka komphumela wokudambisa uketshezi (umphumela we-Lomakin).
