Kunyange zvazvo turbine uye impeller dzimwe nguva zvichishandiswa zvakasiyana mumamiriro emazuva ese, mune zvehunyanzvi uye maindasitiri mashandisiro azvo uye mashandisiro anonyatso siyana. Turbine kazhinji inoreva fan mumotokari kana injini yendege inonatsiridza kushanda kweinjini nekushandisa exhaust magasi kupfuridzira hutsi hwehutsi muinjini. Iyo impeller inoumbwa ne disc, chivharo chevhiri, blade uye zvimwe zvikamu. Mvura inotenderera neine impeller pahupamhi hwepamusoro pasi pechiito chemashizha emagetsi. Iyo gasi inobatwa neiyo centrifugal simba rekutenderera uye kuwedzera kuyerera mune impeller, ichibvumira kuti ipfuure nepamhepo. Kumanikidza kuseri kwe impeller kunowedzera.
1. Tsanangudzo uye maitiro eturbine
Tubhini muchina wemagetsi unotenderera unoshandura simba resvikiro rinoyerera richiita basa remakanika. Icho chimwe chezvinhu zvakakosha zveinjini dzendege, turbines gasi uye turbines. Turbine blades anowanzo gadzirwa nesimbi kana ceramic zvinhu uye anoshandiswa kushandura kinetic simba remvura kuita mechanical simba. Dhizaini uye misimboti yekushanda yeturbine blades inotarisisa mashandisiro avo munzvimbo dzakasiyana dzemaindasitiri, senge ndege, mota, kuvaka ngarava, mainjiniya enjiniya, nezvimwe.
Turbine blades kazhinji ine zvikamu zvitatu zvikuru: chikamu chekupinza, chikamu chepakati uye chikamu chekubuda. Mablades echikamu chekupinza akawedzera kutungamirira mvura kusvika pakati peturbine, mabladhi echikamu chepakati akatetepa kuti avandudze kushanda zvakanaka kweturbine, uye mablades echikamu chekubuda anoshandiswa kusunda mvura yasara kubva muturbine. Iyo turbocharger inogona kuwedzera zvakanyanya simba uye torque yeinjini. Kazhinji, simba uye torque yeinjini mushure mekuwedzera turbocharger ichawedzera ne20% kusvika 30%. Nekudaro, turbocharging zvakare ine zvayakaipira, senge turbo lag, yakawedzera ruzha, uye kupera kupisa kwekupisa.
2. Tsanangudzo uye maitiro e impeller
Impeller inoreva vhiri dhisiki rakashongedzerwa nemashizha anofamba, chinova chikamu che impulse steam turbine rotor. Inogona zvakare kureva zita rezita revhiri dhisiki uye mashizha anotenderera akaiswa pairi. Mapombi akaiswa mumapoka maererano nechimiro chavo uye kuvhura nekuvhara mamiriro, akadai seakavharika ma impeller, semi-akavhurika impellers uye akavhurika impellers. Dhizaini uye kusarudzwa kwezvinhu zve impeller zvinoenderana nerudzi rwemvura yainoda kubata uye basa rainoda kupedzisa.
Basa guru reiyo impeller ndere kushandura simba remagetsi reiyo prime mover kuita static pressure simba uye simba rekumanikidza simba remvura inoshanda. Iyo impeller dhizaini inofanirwa kukwanisa kubata uye zvinobudirira kutakura zvinwiwa zvine hombe particle tsvina kana refu fiber, uye inofanirwa kuve neyakanaka anti-kuvhara kuita uye inoshanda maitiro ekushanda. Kusarudzwa kwezvinhu zve impeller kunokoshawo zvikuru. Zvinhu zvakakodzera zvinoda kusarudzwa maererano nemamiriro ekushanda kwekushanda, zvakadai sesimbi yakakandwa, simbi isina tsvina, ndarira uye kwete-metallic materials.
3. Kuenzanisa pakati pe turbine uye impeller
Kunyangwe maturbines uye ma impellers ese achisanganisira kushandura fluid kinetic simba kuita mechaniki simba, vane misiyano yakakura mumisimboti yavo yekushanda, magadzirirwo, uye mashandisiro. Turbine inowanzoonekwa sechinhu chinodhonza simba mumotokari kana injini yendege iyo inowedzera kushanda kwehutsi hwehutsi kuburikidza nemagasi emhepo, nekudaro ichiwedzera kushanda kweinjini. Iyo impeller inogonesa inoshandura simba remagetsi kuita kinetic simba remvura kuburikidza nekutenderera, inowedzera kudzvanywa kwemvura, uye inoita basa mune akasiyana maindasitiri ekushandisa, sekupomba zvinwiwa zvine zvimedu zvakasimba.
Mumaturbines, mablades anowanzo kutetepa kupa nzvimbo yakakura yeblade uye kuburitsa simba rakasimba rekubuda. Mune impeller, mablades anowanzo kukora kuti ape zvirinani kupikisa uye kuwedzera. Pamusoro pezvo, turbine blades anowanzo gadzirirwa kutenderera uye zvakananga kubuda simba, nepo impeller blades inogona kumira kana kutenderera, zvichienderana nezvinodiwa zvekushandisa2.
4, Mhedziso
Kupfupisa, kune misiyano iri pachena mukutsanangurwa, hunhu uye mashandisirwo ematurbines uye impellers. Turbines anonyanya kushandiswa kuvandudza mashandiro einjini dzinopisa mukati, nepo ma impellers anoshandiswa kutakura uye kugadzira zvinwiwa munzvimbo dzakasiyana siyana dzemaindasitiri. Iyo dhizaini ye turbine inotarisa kune yakawedzera simba uye kugona kwaanogona kupa, nepo impeller inosimbisa kuvimbika kwayo uye kugona kubata zvakasiyana-siyana zvemvura.
