Drip tubing muaj peev xwm nyob rau hauv txoj kab uas hla ntawm ¼ ntiv tes mus txog 1.5 ntiv tes los yog ntau tshaj nyob rau hauv ntau hom thiab yeej ib txwm dub. Nws tuaj yeem yuav hauv 100-, 500-, lossis 1000-ko taw yob. Cov drip tubing diameters suav nrog 3/8-nti (10 hli lossis "380" loj), 1/2-nti (13 hli lossis "500" loj), 5/8-nti (16 hli sab nraud lossis "600" loj) , thiab 5/8-nti (16 mm sab hauv lossis "630" loj). 5/8-inch tubing (qhov loj "600" thiab "630") yog qhov nrov tshaj plaws. Vim nws yog tsim los tiv thaiv tshav ntuj, drip tubing tuaj yeem kav ntev li 30+ xyoo hauv lub hnub.

KHOOM NTAUB NTAWV
Muaj txhua hom fittings uas tuaj yeem txuas rau lub raj xa dej, tab sis qhov loj ntawm lub fittings yuav tsum phim cov tubing. Muaj "T" s, lub luj tshib, thiab cov khoom siv txuas rau txiv neej lossis poj niam lub vaj hose threads rau npe ob peb. Qhov qhib kawg ntawm lub raj yuav tsum tau ntsaws nrog daim duab 8 clamp.
Driplines nyob rau hauv 1000+ ko taw yob uas yog ua los ntawm "600" loj drip tubing nrog emitters pre-installed txhua txhua 12, 18, los yog 24 ntiv tes yuav yuav. Cov emitters sib npaug sib npaug, yog li lawv yog ib qho kev xaiv zoo yog tias koj npaj yuav cog ib lub txaj nrog 2 x 2 kab ntawm cov emitters los yog hauv ib lub vaj teb los yog thaj chaw uas muaj cov nroj tsuag sib npaug. Txawm li cas los xij, yog tias cov nroj tsuag yuav tsum tau watered los ntawm cov drip tubing thiab emitters tsis sib npaug, ces koj yuav zoo dua ntawm kev yuav cov drip tubing thiab emitters kom koj muaj peev xwm zoo dua qhov chaw emitters kom phim koj cov qauv cog.
Microsprinklers thiab microsprayers yog cov yas yas me me thiab cov tshuaj tsuag tsuag uas feem ntau yog mounted rau ntawm qee hom ceg txheem ntseeg yas. Lawv txuas nrog rau ib kawg ntawm qhov ntev ntawm spaghetti tubing uas txuas nrog lub raj xa dej ntawm qhov kawg. Cov no yog cov hybrids ntawm drip irrigation thiab sprinkler irrigation technology, ua rau lawv ntau npaum li cov sprinklers tab sis tseem tsawg npaum li drip emitters.
Microsprinklers tuaj yeem muaj tus nqi ntws ntawm 5-60 nkas loos ib teev, qee zaum ntau dua. Lawv siv ntau nyob rau hauv greenhouses thiab orchards. Lawv kuj tseem siv tau rau hauv toj roob hauv pes nrog ntxhib, xuab zeb av. Cov emitters tsis zoo nyob rau hauv xws li ib puag ncig vim hais tias cov av ntws zoo heev uas cov dej los ntawm lub emitter ntws vertically thiab muaj me ntsis lateral txav ntawm cov dej tawm ntawm lub emitter. Qhov no txwv qhov kev pab cuam hauv cheeb tsam hauv paus. Vim tias microsprinklers txau dej hla thaj chaw loj dua, lawv muaj txiaj ntsig zoo dua dej rau thaj chaw loj dua. Microsprinklers yog siv dav hauv citrus groves, qhov twg cov av yog xuab zeb.
Nyob rau hauv cov cheeb tsam uas cov av feem ntau yog loamy los yog av nplaum, qhov ntws ntsug yog qeeb qeeb thiab cov dej tom qab txav los ntawm cov drip emitter feem ntau yog 2 lossis ntau dua ko taw (tsis yog 4-6 ntiv hauv cov av xuab zeb). Nyob rau hauv toj roob hauv pes nrog loam los yog av nplaum av, ib tug drip emitter yog heev zoo thiab microsprinklers tsis feem ntau siv.

Nyob rau hauv 1985, Datong Locomotive Works pom tau hais tias hluav taws xob locomotives yog qhov tseem ceeb txoj kev loj hlob ntawm Tuam Tshoj railway locomotive thiab dov Tshuag lag luam nyob rau hauv lub neej yav tom ntej, thiab muab tso rau pem hauv ntej lub tswv yim tsim khoom ntawm "Nanzhu (Zhuzhou Electric Locomotive Works) thiab Datong Locomotive Works".
Shaoshan Hom 3 hluav taws xob locomotive yog kuv lub teb chaws thib ob tiam 6-axle neeg nrog caij thiab tsheb thauj mus los. Lub locomotive txais tus choj-hom tag nrho-yoj rectification thiab paub txog thyristor theem-tswj tus voltage tswj. Lub locomotive txais ib-theem AC 25kV 50Hz voltage system thiab muaj kev khiav hauj lwm siab tshaj plaws ntawm 100km / h.
Lub SS3B tsau hnyav hluav taws xob locomotive yog 12-axle freight electric locomotive. Nws muaj ob qhov zoo tib yam 6-qag locomotives txuas los ntawm ib lub coupler thiab ib lub tshuab cua. Ob ntu yog nruab nrog cov khoom siv hluav taws xob high-voltage connectors, tswj cables, thiab kev tiv thaiv network. Kab thiab cua system tswj ducts. Tag nrho lub tsheb tuaj yeem tswj tau synchronously ntawm txhua lub cab. Lub locomotive txais ib-theem fais fab zaus system, voltage 25kV, AC-DC kis tau tus mob, thiab lub siab tshaj plaws kev khiav hauj lwm ceev ntawm lub locomotive yog 100km / h.
Shaoshan 4 txhim kho hluav taws xob locomotive yog 8-axle freight locomotive. Lub locomotive muaj ob zoo tib yam plaub-axle locomotives txuas nrog ib tug coupler thiab ib tug windshield. Ob lub rooj cob qhia yog nruab nrog high-voltage connectors rau cov hluav taws xob system, reconnection tswj cables thiab cua nres system tswj ducts. Tag nrho lub tsheb tuaj yeem synchronously tswj los ntawm tus tsav tsheb cab ntawm ib qho ntawm lub tsheb. Ob lub locomotives tseem tuaj yeem sib cais thiab siv nws tus kheej ua plaub-qag locomotive.
