1. Thawani BEP:

Kugwira ntchito kunja kwa BEP zone ndizomwe zimayambitsa kulephera kwa shaft pampu. Kugwira ntchito kutali ndi BEP kumatha kutulutsa mphamvu zowunikira kwambiri. Kupatuka kwa shaft chifukwa cha mphamvu zama radial kumapanga mphamvu zopindika, zomwe zimachitika kawiri pa shaft pozungulira. Kupinda kumeneku kungapangitse kutopa kopindika kwa shaft. Ma shafts ambiri a pampu amatha kuyendetsa maulendo ambiri ngati kukula kwapatuko kuli kochepa mokwanira.

2. Pampu yopindika:

Vuto lopindika la axis limatsata malingaliro omwewo monga axis yokhota yomwe yafotokozedwa pamwambapa. Gulani mapampu ndi ma shafts osungira kuchokera kwa opanga apamwamba / zowunikira. Zololera zambiri pazitsulo zapampu zili mumtundu wa 0.001 mpaka 0.002 inchi.

3. Cholowa kapena chozungulira chosakwanira:

Chowongolera chosakwanira chimatulutsa "shaft churning" pogwira ntchito. Zotsatira zake ndi zofanana ndi kupindika kwa shaft ndi / kapena kupatuka, ndi shaft ya mpope pampu yakuya ya turbine yakuya bwino adzakwaniritsa zofunika ngakhale mpope wayimitsidwa kuti awonedwe. Zinganenedwe kuti kulinganiza chopondera ndikofunika kwambiri kwa mapampu otsika kwambiri monga mapampu othamanga kwambiri.

4. Zinthu zamadzimadzi:

Nthawi zambiri mafunso okhudza zinthu zamadzimadzi amaphatikiza kupanga mpope wamadzimadzi ocheperako koma kuti athe kupirira kukhuthala kwamadzimadzi. Chitsanzo chosavuta chingakhale pampu yosankhidwa kupopera No. 4 mafuta amafuta pa 35 ° C ndiyeno amagwiritsidwa ntchito kupopera mafuta amafuta pa 0 ° C (kusiyana pafupifupi ndi 235Cst). Kuwonjezeka kwa mphamvu yokoka yamadzi opopera kungayambitse mavuto ofanana.

Komanso dziwani kuti dzimbiri zimatha kuchepetsa kwambiri kutopa kwa zinthu zapampu shaft.

5. Kuthamanga kosinthasintha:

Torque ndi liwiro ndizosiyana. Pamene pampu ikucheperachepera, mphamvu ya shaft ya pampu imawonjezeka. Mwachitsanzo, pampu ya 100 hp imafuna torque yowirikiza kawiri pa 875 rpm monga mpope wa 100 hp pa 1,750 rpm. Kuphatikiza pa malire a brake horsepower (BHP) pa shaft yonse, wogwiritsa ntchito ayenera kuyang'ananso malire ovomerezeka a BHP pakusintha kwa 100 rpm pakugwiritsa ntchito pampu.

6. Kugwiritsa Ntchito Molakwika: Kunyalanyaza malangizo a wopanga kungayambitse mavuto a shaft.

Mapampu ambiri amakhala ndi zinthu zowononga ngati pampu imayendetsedwa ndi injini osati injini yamagetsi kapena turbine ya nthunzi chifukwa cha intermittent vs. torque mosalekeza.

ngati pampu yakuya ya turbine yakuya bwino sichimayendetsedwa mwachindunji kudzera pakulumikiza, mwachitsanzo lamba / pulley, tcheni / sprocket drive, shaft ya pampu ikhoza kutayika kwambiri.

Mapampu ambiri odzipangira okha amapangidwa kuti azikhala ndi lamba ndipo amakhala ndi zovuta zochepa zomwe zili pamwambazi. Komabe, bwino bwino pampu yoyimirira ya turbine opangidwa motsatira ANSI B73.1 specifications si anapangidwa kuti lamba amayendetsedwa. Pamene malamba agwiritsidwa ntchito, mphamvu zovomerezeka za akavalo zidzachepetsedwa kwambiri.

7. Kusintha molakwika:

Ngakhale kusalumikizana pang'ono pakati pa mpope ndi zida zoyendetsa kumatha kuyambitsa mphindi zopindika. Nthawi zambiri, vutoli limadziwonetsa ngati kulephera kwapampu musanayambe kusweka.

8. Kugwedezeka:

Kugwedezeka chifukwa cha zovuta zina osati kusalinganika bwino ndi kusalinganika (mwachitsanzo, cavitation, kudutsa mafupipafupi a tsamba, etc.) kungayambitse kupanikizika pa shaft pampu.

9. Kuyika kolakwika kwa zigawo:

Mwachitsanzo, ngati chowongolera ndi chophatikizira sichinayikidwe bwino patsinde, kukwanira kolakwika kungayambitse kukwapula. Kuvala zokwawa kungayambitse kutopa.

10. Liwiro losayenera:

Kuthamanga kwakukulu kwa mpope kumachokera ku impeller inertia ndi (zotumphukira) malire a liwiro la lamba. Kuphatikiza apo, kuwonjezera pa nkhani ya kuchuluka kwa torque, palinso zoganizira za opareshoni yotsika kwambiri, monga: kutayika kwamadzimadzi (Lomakin effect).
