I-Drip tubing inokwahlukana ngobubanzi ukusuka kwi-intshi eyi-¼ ukuya kwi-intshi ezi-1.5 okanye ngaphezulu kwiintlobo ngeentlobo zeendlela kwaye isoloko imnyama. Inokuthengwa kwi-100-, 500-, okanye i-1000-foot rolls. Imithamo yetyhubhu yokuthontsiza eqhelekileyo ibandakanya i-3/8-intshi (10 mm okanye “380” ubukhulu), 1/2-intshi (13 mm okanye “500” ubukhulu), 5/8-intshi (16 mm ngaphandle okanye “600” ubukhulu) , kunye ne-5/8-intshi (16 mm ngaphakathi okanye "630" ubukhulu). I-5/8-intshi ye-tubing (ubukhulu "600" kunye ne "630") idume kakhulu. Kuba yenziwe ukuba imelane nokukhanya kwelanga, i-drip tubing ingahlala iminyaka engama-30+ elangeni.
Iinkcukacha zeMveliso
IINKCUKACHA ZEMVELISO
Kukho zonke iintlobo zofakelo ezinokuqhotyoshelwa kwi-drip tubing, kodwa ubungakanani be-fitting kufuneka buhambelane ne-tubing. Kukho ii-“T”, iingqiniba, kunye neeadaptha zokuqhagamshela kwimisonto yethumbu yegadi yendoda okanye yabasetyhini ukubiza ezimbalwa. Isiphelo esivulekileyo se-tubing kufuneka sifakwe nge-figure 8 clamp.
Iidriplines in 1000+ imiqulu unyawo ezenziwe "600" ubukhulu drip tubing kunye emitters pre-efakwe zonke 12, 18, okanye 24 intshi zingathengwa. I-emitters ihlukaniswe ngokulinganayo, ngoko ke inketho enkulu ukuba uceba ukunkcenkceshela ibhedi kunye negridi ye-2x2 ye-emitters okanye kwintsimi yeziqhamo okanye indawo enezityalo ezilinganayo. Nangona kunjalo, ukuba izityalo eziza kunkcenkceshelwa ngetyhubhu yokuthontsiza kunye ne-emitters azikho ngokulinganayo, ngoko ungcono ekuthengeni i-drip tubing kunye ne-emitters ukuze ukwazi indawo engcono yokukhupha i-emitters ukuhambelana nepateni yakho yokutyala.
Microsprinklers kwaye iimicrosprayers zizitshizi zeplastiki ezincinci kunye nezitshizi ezihlala zigxunyekwa phezu kolunye uhlobo lwesibonda seplastiki. Ziqhagamshelwe kwelinye icala lobude betyhubhu ye-spaghetti edityaniswe kwityhubhu yokuthontsiza kwelinye icala. Ezi ntlobo zemihlanganiselwa yokunkcenkceshela idriphu kunye neteknoloji yokunkcenkceshela, izenza zisebenze ngakumbi kunezitshizi kodwa zibe nganeno kuneemitters zedriphu.
Microsprinklers inokuba nesantya sokuhamba kwe-5-60 iilitha ngeyure, ngamanye amaxesha ngaphezulu. Zisetyenziswa kakhulu kwii-greenhouses kunye namabhoma. Zikwaluncedo nakwiindawo ezinomhlaba orhabaxa, onesanti. Ii-drip emitters azilunganga kwindawo ezisingqongileyo kuba umhlaba ukhupha kakuhle kangangokuba amanzi aphuma kwi-emitters aphuma eme nkqo kwaye kukho intshukumo encinci kakhulu yasecaleni yamanzi kude ne-emitter. Oku kunciphisa ukhuseleko kwindawo yengcambu. Ngenxa yokuba ii-microsprinklers zitshiza amanzi kwindawo enkulu kakhulu, zisebenza ngakumbi ukunkcenkceshela indawo enkulu yeengcambu. I-Microsprinklers isetyenziswa kakhulu kwi-citrus groves, apho umhlaba unesanti.
Kwiindawo apho umhlaba uvunduvundu okanye udongwe, ukukhupha amanzi okuthe nkqo kucotha kakhulu kwaye intshukumo yamanzi esecaleni ukusuka kwi-drip emitter ihlala i-2 okanye ngaphezulu iinyawo (ngokuchasene ne-4-6 intshi kumhlaba oyisanti). Kwimihlaba enomhlaba ovunduvundu okanye wodongwe, i-drip emitter iyasebenza kwaye ii-microsprinklers azisetyenziswa ngokuqhelekileyo.
Iimveliso ezinxulumeneyo
Ngo-1985, i-Datong Locomotive Works yaqaphela ukuba ii-locomotives zombane yayiyeyona ndlela ibalulekileyo yophuhliso lwe-locomotive kaloliwe wase-China kunye noshishino lwempahla yempahla kwixesha elizayo, kwaye yabeka phambili ingcamango yoyilo lwemveliso ye "Nanzhu (iZhuzhou Electric Locomotive Works) kunye neDatong Locomotive Works".
I-Shaoshan Type 3 locomotive yombane sisizukulwana sesibini selizwe lam labakhweli abane-asi e-6 kunye nelocomotive yempahla. I-locomotive ithatha ibhulorho-uhlobo olupheleleyo ukulungiswa kwamaza kwaye iqonda ukulawulwa kombane ogudileyo wesigaba se-thyristor. I-locomotive ithatha i-single-phase ye-AC 25kV 50Hz inkqubo yombane kwaye inesantya esiphezulu se-100km / h.
I-SS3B egxininisiweyo ye-locomotive yombane enzima yi-12-axle yomthwalo we-locomotive yombane. Iqulethe iilocomotives ezimbini ezifanayo ezine-axle ezi-6 ezidityaniswe yi-coupler kunye ne-windshield. La macandelo mabini axhotyiswe ngesixokelelwano sombane esine-voltage ephezulu, iintambo zokulawula, kunye nokukhusela inethiwekhi. Imibhobho yokulawula umgca kunye nomoya. Isithuthi sonke sinokulawulwa ngolungelelwano kuyo nayiphi na i-cab. I-locomotive ithatha inkqubo ye-frequency power frequency system, i-voltage 25kV, i-AC-DC transmission, kunye nesantya esiphezulu sokusebenza kwi-locomotive yi-100km / h.
I-locomotive yombane i-Shaoshan 4 yi-8-axle yokuthutha impahla. I-locomotive inee-locomotive ezimbini ezifanayo ezine-axle ezine ezidityaniswe yi-coupler kunye ne-windshield. Ezi workshops zimbini zixhotyiswe ngeziqhagamshelo eziphezulu ze-voltage zenkqubo yombane, iintambo zokulawula ukudibanisa kwakhona kunye nemigudu yokulawula i-air brake system. Isithuthi siphela sinokulawulwa ngolungelelwano ukusuka kwikhebhu yomqhubi wayo nayiphi na enye yezithuthi. Izitimela ezimbini zinokwahlulwa kwaye zisetyenziswe ngokuzimeleyo njenge locomotive ene-axle ezine.
