Njengomthengisi weiimpompo ezinodaka ezivela eTshayina, siyaqonda ngokucacileyo ukuba abathengi banemibuzo malunga nobuncinci bokusebenza rhoqo kwiimpompo ze-slurry. Ngokumalunga noku, siya kukunika intshayelelo eneenkcukacha.
Kwizicelo zeiimpompo ezinodaka, umsebenzi wokuguqula amaza ngamanye amaxesha uyafuneka. Umzekelo, udibaniso oluthe ngqo lokudibanisa kufuneka luphunyezwe kwezinye iindawo, okanye ukuqukuqela akuzinzanga kwezinye iisayithi, okanye umgama wothutho umde ngokwentelekiso, njl. njl. iimpompo ezinodaka lokukhupha uxinzelelo zihambelana neyona nto ifunekayo.
Kwinkqubo yokuguqulwa kwamaxesha amaninzi, abantu bahlala bebonisana malunga neyona frequency isezantsi: umntu uthi yi-25Hz, abanye bathi 30Hz, kwaye abanye bathi 5Hz. Ngaba ezi parameters zichanekile? Lithini ixabiso ngqo? Ukumiselwa okungachanekanga kwe-frequency encinci kwinkqubo yokulawula kuya kuchaphazela ukusebenza okuqhelekileyo kwepompo ye-slurry.
Iumenzi weempompo ezinodakaibonisa ukuba la maxabiso mathathu angentla avela kwimiba emibini. Esinye sisixhobo sokuqhuba sempompo, oko kukuthi i-motor kunye nenye yimpompo yodaka ngokwayo.
Mna: Ubuncinci bokusebenza rhoqo kweenjini zeVSD
1. Ukuthetha ngethiyori yodwa, i-frequency ephantsi yokusebenza enokuthi i-VSD motor iqhube i-0Hz, kodwa i-0HZ motor ayinayo isantya, ngoko ke oku akunakuthathwa njengeyona ndlela iphantsi yokusebenza;
2. Uluhlu oluvumelekileyo lwesantya sokusebenza kweenjini ezahlukeneyo zeVSD luhlukile;
3. Ukuyibeka ngokulula, ukuba isantya sokulawulwa kwesantya se-VSD motor yi-5-50Hz, ngoko ke ubuncinci obuvumelekileyo obusebenzayo be-frequency frequency motor yi-5Hz;
4. Isizathu sokuba kutheni i-motor frequency variable inokusebenza kwiifrikhwensi ezininzi.
(1) Injini yeVSD inomsebenzi olungileyo wokuphelisa ubushushu. Ukupholisa kwayo kunye nenkqubo yokungenisa umoya iqhutywa yi-wiring ezimeleyo. Inokunyanzeliswa ukuba ikhuphe ubushushu ukuqinisekisa ukuba i-VSD motor inokusebenza kwiifrikhwensi ezahlukeneyo. I-motor inokuvelisa ubushushu kwaye ichithe ixesha;
(2) Ukusebenza kwe-insulation ye-VSD motor ilungile, kwaye inokuthatha impembelelo enayo kwi-motor ye-VSD, ukusuka kumbane ohlukeneyo kunye nombane wee-frequencies ezahlukeneyo.
5. Akukhuthazwa ukuba usebenzise i-motor frequency frequency kwi-low frequency. Emva kokuba i-motor igijima kwi-frequency ephantsi ixesha elide, ithandwa kakhulu ekuveliseni ubushushu, okuya kubangela ukuba imoto iphele. Eyona frequency yokusebenza yemoto kukusebenza kufutshane nesantya sokusebenza rhoqo.
6. Uluhlu lokuguqulwa kwamaza ombane oqhelekileyo osetyenziswa rhoqo yi-1-400HZ; kodwa kwisicelo esisebenzayo, ngokuqwalasela ukuba umgangatho we-motor yaseTshayina ucwangciswe ngokokuhamba kwamandla ka-50HZ, isicelo sinomlinganiselo phakathi koluhlu lwe-20-50HZ.
Ke ngoko, ubuncinci ubuncinci obuvumelekileyo bemotor-frequency motor inxulumene noluhlu oluthile lokusebenza kwama frequency emoto eguquguqukayo. Ngokubanzi, elona xabiso liphantsi elivunyelwa yimoto yeVSD linokuthathwa.
II: ubuncinci besantya sokusebenza kwiimpompo ze-slurry
Ipompo nganye ye-slurry ine-curve yayo yokusebenza, echaza ubuncinci besantya sokusebenza sempompo. Kuphela xa isantya siphezulu kunesantya esichaziweyo, umpompo unokusebenza ngokuqhelekileyo. I-frequency kwesi santya bubuncinane bokusebenza rhoqo kwimpompo eludaka.
Kakade ke, kukho ezinye iimpembelelo ezifana nesantya sokuhamba kwemibhobho. Ngamafutshane, kunokuthathelwa ingqalelo ukuba la manqaku mabini angasentla, oko kukuthi, ukuphindaphinda okugqitywe bubuncinane besantya sempompo eludaka kunye nobuncinci bokusebenza kwemoto eguquguqukayo zizinto ezimbini ezichaphazela ubuncinci bokusebenza koludaka. impompo. Phakathi kwezi zinto zimbini, ixabiso le-frequency liphezulu lincinci yokusebenza rhoqo kwimpompo ye-slurry.
