Mapangidwe onse a makina opangira njerwa ndi ophatikizana, okhazikika, otetezeka komanso odalirika. Njira yonse ya PLC yolamulira mwanzeru, ntchito yosavuta komanso yomveka bwino. Kugwedezeka kwa ma hydraulic ndi kukanikiza kachitidwe ka makoleji ndi mayunivesite kumatsimikizira kulimba kwapamwamba komanso zapamwamba zazinthu. Zapadera kuvala zosagwira zitsulo zakuthupi, kuonetsetsa ntchito yaitali, bwino kuchepetsa nkhungu ndalama. Makina opangira njerwa zonyansa ndi mtundu wa makina a njerwa, zida ndi zida zina zamakina a njerwa ndizofanana, koma kupanga zinthu zopangira sikufanana. Ndi kupita patsogolo kwa nthawi ndi chitukuko cha mafakitale, zinyalala zomanga zimatha kuwoneka paliponse. Makina opangira njerwa zinyalala akhala chida chofunikira chopangira njerwa.

Mzere wopanga njerwa wa zinyalala zomangira zimatenga zinyalala zomanga ngati zopangira, zimatengera kupulumutsa mphamvu, kuchepetsa kugwiritsa ntchito ndi kuchepetsa umuna monga momwe amapangira malingaliro, komanso pamaziko a zojambula zaukadaulo wapamwamba kunyumba ndi kunja, komanso malinga ndi momwe zinthu zilili ku China, imapanga ndikupanga mzere wodzipangira woteteza chilengedwe, kupulumutsa mphamvu ndi kusawotcha njerwa zokhala ndi ufulu wodziyimira pawokha waluntha. kukhala ndi:

1. pafupipafupi kusinthasintha ndi matalikidwe kusinthasintha kugwedera anatengera kukwaniritsa cholinga cha compactness mkulu ndi kupulumutsa mphamvu ngakhale popanda kuwotcha zobwezerezedwanso njerwa;

2. Kugwiritsa ntchito zinyalala zomangira ngati zinthu zopangira njerwa zosawotchedwa zobwezerezedwanso, mitundu ingapo ya njerwa zosawotchedwa zobwezerezedwanso zitha kupangidwa, monga njerwa wamba, njerwa zonyamula katundu, njerwa zopepuka, njira yapapazi ndi kanjira yosawotcha njerwa zobwezerezedwanso, udzu wosawotchedwanso njerwa, malire osawotchedwa, njerwa zosawotchedwa, zowumbidwanso ndi zina. mawonekedwe ofunikira ndi kukula kwake

3. Kapangidwe kakang'ono, kufananiza kosinthika, kupanga bwino kwambiri, kupulumutsa mphamvu ndi kuteteza chilengedwe;

4. Mapangidwe amtundu, zosavuta kukhazikitsa, kukonza ndi kukonza;

5. Mkulu digiri ya zochita zokha ndi ntchito yosavuta;

6. Mtengo wotsika mtengo.
