Valulle mtundu wa singano

Valusi ya singano Kapangidwe kake kake kamapangitsa kuti zikhale zabwino pazomwe mungagwiritse ntchito bwino kwambiri, mabungwe okakamizidwa, kapena njira yosinthira mu mafakitale.

Valavu imakhala ndi thupi, pulagi yooneka ngati singano (kapena tsinde), mpando wa Valain, ndi makina osintha. Kholo la singano, wokhala ndi nsonga yolumikizidwa kapena yozungulira, imasuntha mkati mwa thupi la valavu pomwe chogwirizira kapena wochita chipongwe chazungulira. Pamene singano imayamba kulowa panjira yotuluka, imaletsa malo okhala pamtanda, kuwonjezereka pokana ndi kuchepetsa mtengo. Kuyenda mzerewu kumapereka mwayi wowonjezera, kupangitsa ogwiritsa ntchito kuti akwaniritse kutentha ndi kuwongolera kwambiri (nthawi zambiri mkati mwa ± 2% ya mtengo wake). Mwachitsanzo, m'matola a labotale, valavu imatha kuyendetsa magesi omwe akuwonongeka ndi kupanikizika kochepa kuponderezedwa, kuonetsetsa mwayi woyesa.

Kukonza pafupipafupi kumaphatikizapo kuyang'ana ku singano ndi mpando wovala, monga momwe amagwiritsidwira ntchito nthawi yayitali kungasinthe magwiridwe antchito. Zopanga zamakono zimaphatikizira zokutira za anti-kukokoloka (mwachitsanzo, cangsten Carbide) pa singano padziko lapansi kuti iwonjezere moyo. Kuphatikiza apo, mavulu anzeru amphamvu okhala ndi ma sensa okhala ndi malo opangidwa, akumawathandiza kuwunikira nthawi yeniyeni yowunikira komanso njira zakutali munjira zokha.
