Tsamba lotha kutha ntchito la pulawo losawonongeka ndi madzi la ulimi Chithunzi Chowonetsedwa

Tsamba lolimba losagwira ntchito la hydraulic losinthika la pulawo

Kufotokozera Kwachidule:

Ili ndi pulawo lolimba kwambiri, losatha kusweka, lopangidwa ndi chitsulo chapamwamba kwambiri komanso lokonzedwa bwino kuti likhale lolimba komanso lolimba. Ngodya yake yolowera m'nthaka yopangidwa mwasayansi imachepetsa kukana ndikuwonjezera mphamvu yoswa nthaka. Yoyenera mikhalidwe yosiyanasiyana ya nthaka, imakulitsa kwambiri magwiridwe antchito a ulimi ndipo ndi chowonjezera chabwino kwambiri pa ntchito zamakina a ulimi.

Monga gawo lalikulu la makina olima omwe amakhudza nthaka mwachindunji ndikuchita ntchito zodula ndikuswa nthaka, ubwino wa tsamba lolima umatsimikizira mwachindunji momwe ulimi umagwirira ntchito komanso ndalama zogwirira ntchito. Tsamba lolima ili lapangidwira makamaka mapulawo osinthika a hydraulic ndi mitundu yosiyanasiyana ya mapulawo opachikidwa, ndipo limagwiritsa ntchito ukadaulo wapamwamba wochizira kutentha ndi zinthu zachitsulo champhamvu kwambiri, cholinga chake ndikupatsa ogwiritsa ntchito chidziwitso chabwino kwambiri cha ulimi chomwe chili "chakuthwa, chosawonongeka, komanso cholimba".

Yopangidwa ndi zipangizo zapamwamba kwambiri kuti isawonongeke kwambiri: Chogulitsachi chimagwiritsa ntchito chitsulo cha manganese cha 65Mn kapena chitsulo cha boron chapamwamba cha 30MnB (kutengera chitsanzo) ngati maziko. Pambuyo pa njira zambiri zotenthetsera kutentha (kuzima konsekonse + kutentha kwapafupi), kuuma kwa pamwamba kumafika pa 38-45HRC, pomwe pakati pake pamakhala kulimba kwambiri. Poyerekeza ndi mapulawo wamba achitsulo cha carbon, nthawi yake yogwiritsidwa ntchito imatha kuwonjezeredwa ndi nthawi 2-3, zomwe zimathandiza kuthana ndi dothi lamchenga mosavuta, dothi lolemera la dongo, komanso nyengo yovuta ya nthaka ndi miyala, zomwe zimachepetsa kwambiri kuchuluka kwa malo osinthira minda ndikukupulumutsirani nthawi yamtengo wapatali yolima.

Yopangidwa mwasayansi kuti ilowe m'nthaka yosalala: Pogwiritsa ntchito kapangidwe kake kolunjika bwino komanso kolunjika bwino, kuphatikiza ndi ukadaulo wodzinola wekha, kukangana pakati pa pulawo ndi nthaka panthawi yolima kumathandiza kuti tsamba likhale lakuthwa, zomwe zimachepetsa kukana kwa mphamvu yokoka ndi kugwiritsa ntchito mafuta a thirakitala (kusunga mafuta enieni a 5%-8%). Nsonga yakuthwayo imadula mosavuta ziputu za mbewu, zomwe zimapangitsa kuti nthaka ikhale yolimba, kuphimba bwino, komanso kukonza bwino kusweka kwa nthaka.

Kuwongolera khalidwe mozama komanso kuyenerera bwino: Chogulitsachi chimapangidwa pogwiritsa ntchito zinyalala zolondola kuti zitsimikizire kuti malo oikira mabowo ndi kutalika kwa malo opindika ndi ofanana, zomwe zimapangitsa kuti chigwirizane bwino ndi pulawo loyambirira, zomwe zimapangitsa kuti pasakhale kufunikira kosintha kapena kusintha mabowo pamalopo. Pamwamba pake pamagwiritsidwa ntchito popopera kapena kufinya kuti dzimbiri lisawonongeke bwino panthawi yosungira ndi kunyamula, zomwe zimapangitsa kuti chikhale chokonzeka kugwiritsidwa ntchito nthawi yomweyo mutakhazikitsa.
