Njira yogwirira ntchito ndi njira zodzitetezera za mapasa-screw thovu granulator

Zida zimadutsa pa doko lodyera lathovu lawiri-screwgranulator. Pansi pa zomangira zozungulira, amakulungidwa kukhala mipira ndikupita patsogolo motsatira ma screw grooves. Chifukwa cha kumeta, kuponderezana ndi zotsatira zochititsa chidwi za zomangira, zipangizozo zimasakanikirana ndi pulasitiki, ndi kutentha ndi kupanikizika kumawonjezeka pang'onopang'ono, kuwonetsa kutuluka kwa viscous. Kenako amadutsa mutu wakufa pazovuta zina ndi kutentha, ndipo pamapeto pake zinthu zomwe zimafunikira zimapezedwa.

Njira zodzitetezera pakugwiritsa ntchito gawo lalikulu lamapasa-screw thovu granulator

1. Mphamvu yovotera ya chipangizo chachikulu ndi mphamvu yamagetsi yamoto. Panthawi yogwira ntchito bwino, iyenera kuyendetsedwa pansi pa 80% yazomwe zidavotera, ndikusiya njira ina kuti mupewe kuchulukitsitsa (chonde onaninso dzina la motor nameplate pakali pano). Ma voliyumu ovotera ndi ma frequency a unit yayikulu ayenera kuwongoleredwa pamwamba pa 50% ya voliyumu yovotera ndi ma frequency pakugwira ntchito bwino.

2. Kuthamanga kwa mutu kumakhala ndi mita yowonetsera digito. Chiwonetsero chodziwika bwino cha digito chiyenera kukhala pansi pa 10MPa. Wogwiritsa ntchito amayenera kuyang'anira mawonekedwe a digito nthawi zonse. Ngati ipitilira 15MPa, akuyenera kuyang'ana ngati njira yolowera yatsekedwa. Kudyetsa kuyenera kuyimitsidwa nthawi yomweyo, ndipo liwiro la makina akuluakulu liyenera kuchepetsedwa pang'onopang'ono kuti musinthe mawonekedwe a digito pa sensa kukhala pansi pa 10MPa. Ngati chiwonetsero cha digito chikadali chachikulu, makinawo ayenera kutsekedwa pamanja kuti awonedwe.

3. Ogwira ntchito ayenera kuyang'ana nthawi zonse mchira wothira mafuta oyeza kuthamanga kwa mafuta (mtengo wake ndi 0.1-0.2MPa). Ngati ndi yotsika kuposa 0.05MPa, makinawo amayenera kuyimitsidwa nthawi yomweyo kuti ayang'ane mayendedwe amafuta, pampu yamafuta ndi pampu yamafuta, kuti ateteze magwiridwe antchito abwinobwino a magiya opatsira.

4. Pamene mukugwira ntchito bwino, payenera kukhala zolemba za ntchito.
