Kuenzanisa simba re axial mumapombi e centrifugal ane nhanho dzakawanda tekinoroji yakakosha yekuona kuti mashandiro aro agadzikana. Nekuda kwekurongeka kwema impellers, masimba e axial anoungana zvakanyanya (kusvika matani akati wandei). Kana zvisina kuenzana zvakanaka, izvi zvinogona kukonzera kuwandisa kwemabheya, kukuvara kwechisimbiso, kana kutokundikana kwemidziyo. Pazasi pane nzira dzakajairika dzekuenzanisa simba re axial, pamwe chete nemisimboti yadzo, zvakanakira, uye zvadzisina kunaka.
1.Kurongeka kweImpeller Yakaenzana (Kudzokera Kumashure / Kutarisana)
Mukugadzirwa kwemudziyo we axial force balance wepombi yemazuva ano ye centrifugal, danho re impeller rinowanzo sarudzwa senhamba yakaenzana, nekuti kana danho re impeller riri nhamba yakaenzana, nzira yekugovera impeller symmetrical inogona kushandiswa kuyera simba re axial remuchina, uye simba re axial rinogadzirwa ne symmetrically distribution impeller mukushanda kwacho rakaenzana muhukuru uye rakapesana, uye richaratidza mamiriro e equilibrium padanho re macroscopic. Mukugadzirwa kwacho, zvinofanira kucherechedzwa kuti saizi yekuvharira ye sealing throttling isati yapinda ye reverse impeller inoenderana nedhayamita ye impeller kuti ive nechokwadi chekuvharwa kwakanaka.
●Nheyo: Ma imperler ari pedyo akarongwa nenzira dzakasiyana kuitira kuti masimba avo e axial akwanise kudzimana.
●Kutevedzana: Maseti maviri emaimpeller akaiswa zvakaenzana akatenderedza pombi yepakati.
●Kutarisana: Maimpeller akarongwa akatarisa mukati kana kunze muchimiro chegirazi.
●Zvakanakira: Hapana mimwe michina inodiwa; chimiro chiri nyore; kushanda zvakanaka kwekuenzanisa (kupfuura 90%).
●Zvakashata: Dhizaini yedzimba dzepombi yakaoma; kugadzirisa nzira yekuyerera yakaoma; inoshanda chete kumapombi ane huwandu hwakafanana hwematanho.
●Mashandisirwo: Pombi dzekudya dzebhoyira dzine simba guru, pombi dzepetrochemical dzakawanda.
2. Ngoma Yekuyera
Chimiro chedhiramu re balance (chinozivikanwawo se balance piston) hachina nzvimbo yakasimba yekumhanya, iyo inogona kutsiva chikamu chikuru che axial thrust, asi kwete yese axial thrust, uye hapana imwe muripo wekuwedzera kana uchifamba munzvimbo ye axial, uye mabheya e thrust anowanzo dikanwa. Dhizaini iyi ichave ne internal recirculation yakakwira (internal leakage) asi inoshivirira zvakanyanya kune ma startup-up, shutdowns, uye mamwe mamiriro e transient.
●Nheyo: Drum rakatenderera rinoiswa mushure meimpeller yedanho rekupedzisira. Mvura ine simba guru inodonha nepakati pedhiramu nekaburi ichipinda mukamuri rine simba shoma, zvichiita kuti pave nesimba rinorwisa.
● Amabhenefiti: Kugona kwakasimba kwekuenzanisa, kwakakodzera mapombi ane simba guru, ane matanho akawanda (semuenzaniso, matanho gumi+).
●Zvakashata: Kurasikirwa nekudonha kwemvura (~3–5% yehuwandu hwekuyerera kwemvura), zvichideredza kushanda zvakanaka. Zvinoda mamwe mapaipi ekuenzanisa kana masisitimu ekudzokorora mvura, zvichiwedzera kuoma kwekugadzirisa.
●Mashandisirwo: Mapombi makuru epakati pemasitepisi akawanda (semuenzaniso, mapombi emapaipi ari kure).
3.Dhisiki Yekuyera
Senzira yakajairika yekugadzira mukugadzira mudziyo we axial force balance wepombi yemazuva ano ine masiteji akawanda, nzira ye balance disc inogona kugadziriswa zvine mwero zvichienderana nezvinodiwa pakugadzira, uye balance force inonyanya kugadzirwa nechikamu chiri pakati pe radial clearance ne axial clearance yediski, uye chimwe chikamu chinonyanya kugadzirwa ne axial clearance nechikamu chekunze che balance disc, uye aya maviri balancing force anoita basa rekuenzanisa axial force. Zvichienzaniswa nedzimwe nzira, mukana we balance plate method ndewekuti dhayamita ye balance plate yakakura uye sensitivity yakakwira, izvo zvinovandudza kushanda kwemudziyo wemidziyo. Zvisinei, nekuda kwe axial running clearance diki, dhizaini iyi inogona kusakara kana kukuvara mumamiriro ekunze.
●Nheyo: Dhisiki inofambiswa inoiswa mushure me impeller yekupedzisira. Musiyano wekumanikidzwa kwedhisiki unogadzirisa nzvimbo yayo kuti irwise simba re axial.
●Zvakanakira: Inozvigadzirisa yega kuti ienderane nekusiyana kwesimba re axial; kunyatsorongeka kwepamusoro.
●Zvakashata: Kukweshana kunokonzera kupera, zvichida kutsiviwa nguva nenguva. Inonzwa kuchena kwemvura (tinhu tunogona kuvharira diski).
●Mashandisirwo: Pombi dzemvura yakachena dzinotanga nematanho akawanda (dzichitsiviwa zvishoma nezvishoma nemadhiramu ekutsinhanisa).
4.Kuenzanisa Drum + Disk Musanganiswa
Kana tichienzanisa nenzira ye balance plate, nzira ye balance plate drum yakasiyana nekuti saizi yechikamu chayo che throttle bushing yakakura kupfuura saizi ye impeller hub, nepo balance disc ichida saizi ye throttle bushing kuti ienderane nehukuru hwe impeller hub. Kazhinji, munzira yekugadzira balance plate drum, balance force inogadzirwa ne balance plate inodarika hafu ye total axial force, uye huwandu hwepamusoro hunogona kusvika 90% ye total axial force, uye zvimwe zvikamu zvinonyanya kupihwa ne balance drum. Panguva imwe chete, kuwedzera zvine mwero balance force ye balance drum kuchaderedza balance force ye balance plate, uye kunoderedza saizi ye balance plate, nokudaro zvichideredza wear degree ye balance plate, zvichivandudza hupenyu hwebasa rezvikamu zvemidziyo, uye kuve nechokwadi chekuti pombi ye centrifugal inoshanda zvakanaka.
●Nheyo: Ngoma inobata simba guru re axial, ukuwo dhisiki ichigadzirisa simba rasara.
●Zvakanakira: Inobatanidza kugadzikana uye kuchinjika, yakakodzera mamiriro ekushanda anochinja-chinja.
●Zvakashata: Maumbirwo akaomarara; mutengo wakakwira.
●Mashandisirwo: Pombi dzemaindasitiri dzinoshanda zvakanaka (semuenzaniso, pombi dzemvura dzinotonhodza dzinoshandisa nyukireya).
5. Mabheya Ekufambisa (Kuenzanisa Kwekubatsira)
●Nheyo: Mabheya ebhora rekubatana reAngular kana mabheya eKingsbury anotora simba re axial rinosara.
●Zvakanakira: Backup yakavimbika yedzimwe nzira dzekuenzanisa.
●Zvakashata: Inoda mafuta anozorwa nguva dzose; hupenyu hupfupi pasi pemitoro yakakwira.
●Mashandisirwo: Mapombi madiki kusvika pakati nepakati kana mapombi anomhanya zvakanyanya.
6. Dhizaini yeImpeller yeKubvisa Kaviri
●Nheyo: Chinodhonza mweya chinodhonza mweya kaviri chinoshandiswa padanho rekutanga kana repakati, chichienzanisa simba re axial kuburikidza nekupinda kwemhepo kudivi rimwe chete.
●Zvakanakira: Kuenzanisa kunobudirira uku uchivandudza mashandiro e cavitation.
●Zvakashata: Inoenzanisa simba re axial rechikamu chimwe chete chete; dzimwe nzira dzinodiwa pamapombi ematanho akawanda.
7. Maburi eHydraulic Balance (Maburi eImpeller Backplate)
●Nheyo: Maburi anoboorwa muimpeller backplate, zvichibvumira mvura ine simba repamusoro kuti idzoke kunzvimbo ine simba repasi, zvichideredza simba re axial.
●Zvakanakira: Zviri nyore uye zvakachipa.
●Zvakashata: Inoderedza kushanda zvakanaka kwepombi (~2–4%).Yakakodzera chete kushandiswa kwesimba rakaderera re axial; kazhinji inoda mabheyaringi ekuwedzera.
