Iikholamu yokuphakamisayahlulwe kakhulu yangamacandelo amathathu: inxalenye yekholamu, inkqubo yokulawula kunye nenkqubo yamandla.
Inkqubo yolawulo lwamandla ikakhulu yi-hydraulic, pneumatic, electromechanical, njl. Umgaqo wokusebenza kwenkqubo yolawulo ephambili ngolu hlobo lulandelayo.
Emva kweminyaka yophuhliso, ikholamu iye yaphuhliswa yaba ziintlobo ngeentlobo zeendlela. Inkqubo yamandla ikakhulu ibandakanya ezi ntlobo zilandelayo:
1. Ikholamu yokuphakamisa ezenzekelayo yoxinzelelo lomoya: Umoya usetyenziswa njengendawo yokuqhuba, kwaye iyunithi yamandla e-pneumatic yangaphandle isetyenziselwa ukuqhuba ukunyuka nokuwa kwekholamu.
2. Ikholamu yokuphakamisa ezenzekelayo ngokupheleleyo nge-hydraulic. Ikholamu yokuphakamisa ezenzekelayo: ioyile ye-hydraulic njengesixhobo sokuqhuba. Kukho iindlela ezimbini zokulawula, oko kukuthi, ngokusebenzisa iyunithi yamandla e-hydraulic yangaphandle (inxalenye yokuqhuba yahlulwe kwi-cylinder) okanye iyunithi yamandla eyunithi ye-hydraulic eyakhelwe ngaphakathi (inxalenye yokuqhuba ibekwe kwi-cylinder) ukuqhuba isilinda ukuze inyuke kwaye iwe.
3. Ukuphakamisa ngokuzenzekelayo kwe-electromechanical: Ukuphakamisa nokwehlisa ikholamu kuqhutywa yi-motor eyakhelwe ngaphakathi kwikholamu.
Umgaqo wokusebenza kwenkqubo yokulawula ikholamu yokuphakamisa:
1. Umgaqo oyintloko kukuba isiphelo sokufaka isignali (ibhokisi yokulawula kude/yeqhosha) sithumela isignali kwinkqubo yolawulo, kwaye inkqubo yolawulo ye-RICJ icubungula isignali ngenkqubo yesekethe yelogic okanye inkqubo yolawulo lwelogic olucwangcisiweyo lwe-PLC. Ngokomyalelo, i-output relay ilawulwa ukuqhuba i-AC contactor ukuze itsale kwaye iqalise i-power unit motor.
2. Inkqubo yolawulo ingalawulwa yinkqubo yesekethe ye-relay logic okanye i-PLC. Ukongeza kwizixhobo zolawulo lokusebenza eziqhelekileyo ezifana nebhokisi yamaqhosha kunye nolawulo olukude, inokudityaniswa nezinye izixhobo zolawulo lokungena nokuphuma kunye neqonga lolawulo eliphakathi ukuya kwizixhobo zolawulo.
3. Emva kokuba injini iqalisiwe, iqhuba igiya. Ipompo iyajikeleza, icinezele ioyile ye-hydraulic kwi-hydraulic cylinder ngevalvu edibeneyo, kwaye ityhala i-hydraulic cylinder ukuba yande kwaye inciphe. Iikholamu zokuphakamisa zahlulwe zibe zinqanaba eliphezulu lokhuseleko kunye nenqanaba labantu abaqhelekileyo ngokweemeko ezahlukeneyo. Izikolo kunye nezinye iindawo.
Umgaqo osebenzayo wenkqubo yokulawula ikholamu esezantsi Ikholamu yokuphakamisa yahlulwe kakhulu ibe ngamacandelo amathathu: inxalenye yekholamu, inkqubo yolawulo kunye nenkqubo yamandla. Inkqubo yokulawula amandla ikakhulu yi-hydraulic, pneumatic, electromechanical, njl.
Ukuze ufumane ulwazi oluthe kratya ngemveliso kunye nenkampani,unxibelelwanokuthi ngoko nangoko.
