Taghadh modail bhalbhaichean criomate Pneuctico
Raon teòthachd : A rèir riatanasan teòthachd ìosal sònraichte, tagh am modal bhalbhaichean a dh 'fhaodas atharrachadh ris an raon teothachd. Mar as trice feumar baistidhean smachd cryogenic a bhith comasach air seasamh a-steach gu math ìosal, gus an feumar teòthachd gu math ìosal a sheasamh, mar sin feumar bhalbhaichean air a dhèanamh le stuthan sònraichte a thaghadh.
Seòrsa bhalbhaichean : A rèir riatanasan gnàthach suidheachadh sònraichte agus riatanas smachd, a 'riaghladh bhalbhaichean glaodhach, msaa. Tha feartan toraidh eadar-dhealaichte aig diofar chliabh de bhalbhaichean.
Modh Smachd : Tagh bhalbhaichean smachd pneumatic a rèir feumalachdan fìor, a dh 'fhaodadh a bhith nan cleasachd aon-cheum (smachd aon-shligheach) no cleasachd dùbailte (smachd dùbailte agus àithne adhartach). A rèir riatanasan an t-siostam smachd, tagh am modh smachd iomchaidh.
Faodaidh tu beachdachadh air na factaran gu h-àrd, faodaidh tu am modail bhalbhaichean smachd cryogenic freagarrach a thaghadh. Tha toraidhean eile aig a 'chompanaidh againn cuideachd: bhalbhaichean ball dealain, bhalbhla ball dealain, bhalbhla dealan-dè pleuma , msaa, fàilte a cho-chomhairleachadh.
