KUONA MABUKU OBWERA JEKELO: KUPANGITSA MAVUTO

Kuthetsa mavuto kungathe kuchitika pamene injini ikugwira ntchito komanso pamene yazimitsidwa.Kuthetsa mavuto pamene injini ikuyenda

1 Werengani ndikuyerekeza mphamvu yamagetsi ndi nthawi yamagetsi

Chizindikiro cha jakisoni chikhoza kuwonetsedwa pogwiritsa ntchito oscilloscope.Pachifukwa ichi, gwirizanitsani mzere woyezera ku mzere wa chizindikiro, ndi mzere wina ku pini yoyenera.Ndi injini ikuyenda, ndizotheka kuwerengera mphamvu yamagetsi ndi nthawi yamagetsi (nthawi yotsegulira) kuchokera pamtundu wa siginecha.Mukatsegula valavu yothamanga, nthawi ya pulse iyenera kuwonjezeka panthawi yowonjezereka, ndipo ndi liwiro la injini nthawi zonse (mozungulira 3000 RPM) iyenera kubwereranso, kapena pansipa, mtengo wosagwira ntchito.Zotsatira za masilinda amunthu zimatha kufananizidwa ndi mnzake, ndipo izi zitha kupereka chizindikiritso cha zolakwika, mwachitsanzo kusakwanira kwamagetsi.

2 Yezerani kuthamanga kwamafuta ndikuwunika momwe mayamwidwe amagwirira ntchito komanso kutulutsa kwagawo

Mayesero ena ofunikira ndikuyesa kuthamanga kwa mafuta, kuti azindikire zinthu zina zomwe zingakhale zolakwika (pampu yamafuta, fyuluta yamafuta, chowongolera kupanikizika), ndikuyang'ana njira zolowera ndi zotulutsa zomwe zimatuluka, kuti mupewe zotsatira zabodza.Ngati sensa ili ndi cholumikizira cha 2-pin, ndiye kuti ndi cholumikizira chothandizira.Pachifukwa ichi, kukana kwamkati, kutha kwafupipafupi kuti apangidwe, ndi chizindikiro chikhoza kutsimikiziridwa.

Kuti muchite izi, chotsani kugwirizana kwa pulagi ndikuyang'ana kukana kwamkati kwa sensa.Ngati mtengo wotsutsa wamkati ndi 200 mpaka 1,000 ohms (malingana ndi mtengo wamtengo wapatali), sensor ili bwino.Ngati mtengo ndi 0 ohms, pali dera lalifupi, ndipo ngati pali kupuma.Kuyesa kwa kagawo kakang'ono ka chimango kumachitika pogwiritsa ntchito ohmmeter kuchokera pa pini yolumikizira kupita kugalimoto

pansi.Mtengo wotsutsa uyenera kukhala wopanda malire.Kuyesa pogwiritsa ntchito oscilloscope kuyenera kubweretsa chizindikiro cha sinus cha mphamvu zokwanira.Pankhani ya jenereta ya Hall, magetsi okhawo omwe ali ngati siginecha ya square wave ndi magetsi operekera ayenera kuyesedwa.Izi ziyenera kubweretsa chizindikiro cha square wave kutengera liwiro la injini.Tiyenera kubwereza panthawiyi kuti kugwiritsa ntchito ohmmeter kungawononge jenereta ya Hall.
