I-Differential Pressure Switch

Iswishi yokucindezela okuhlukile iyiswishi yokulawula ingcindezi ekhethekile, esekelwe emehlukweni wokucindezela phakathi kwezingxenye ezihlukahlukene, futhi idlulisa ulwazi ngamasignali kagesi ukuze kulawulwe ukuvala noma ukuvulwa kweswishi. Umzimba we-valve weswishi yokucindezela okuhlukile kanye nohambo. ama-switch ahlanganiswa epuleti eliphansi. Ngaphansi kwesenzo sokucindezela, igrisi ingena emgodini ongakwesokudla we-value yokushintsha i-valve piston yomzimba isuka epayipini elikhulu B, bese ipayipi elikhulu A liyathululwa. Uma umehluko wengcindezi phakathi kwamapayipi amabili amakhulu ufinyelela inani elimisiwe, i-piston. inqoba amandla asentwasahlobo endaweni yesokunxele bese iya kwesokunxele, bese iphusha iswishi yokuhamba ukuze ivale othintana naye, bese ithumela isignali ye-pulse kubhokisi lokulawula ugesi wesistimu ukuze iyale i-valve ehlehlayo ukuthi ishintshe indlela.Ngalesi sikhathi, okuyinhloko ipayipi A liyacindezelwa, futhi u-B uyathululwa. I-piston igxile ngaphansi kwesenzo sentwasahlobo emgodini onamaphethelo amabili, othintana nabo be-stroke switch 1 no-2 banqanyuliwe, futhi ibhuloho lokuxhumana lisesimweni sokungathathi hlangothi.

Uhlelo luqala umjikelezo wesibili. Uma umehluko wengcindezi phakathi kwepayipi elikhulu A no-B ufinyelela inani elimisiwe futhi, i-piston iya kwesokudla, othintana nabo be-stroke switch 3 no-4 bayavalwa, futhi isignali ye-pulse iphinde ibangele i-valve ehlehlayo ohlelweni ukuthi ishintshe indlela. Qala umjikelezo olandelayo womsebenzi.
