Inkqubo yesakhiwo se-laminator ngokuyinhloko iqulethwe ngamacandelo amane: inkqubo yokulayisha kunye nokukhupha, inkqubo yokufudumala, inkqubo yoxinzelelo, kunye nenkqubo yokukhusela. Inkqubo yokufudumala iquka into yokulinganisa, isilawuli, kunye ne-heater. Umsebenzi wayo kukunyusa nokugcina ubushushu bamanzi akwisikhongozeli. Ukushisa kudluliselwa emanzini kwiiplate ze-capacitor ezixinzelelweyo, ziqinisekisa ukufudumala okufanayo. Ukufudumala kunciphisa iiplate, kuququzelele ukunyanzeliswa kunye nokuthintela ukuqhekeka phantsi koxinzelelo.
Isixhobo sokufudumeza yintsimbi yokufudumeza ipleyiti engenasici esongelwe kumphezulu wangaphandle wesikhongozeli esitywiniweyo. Xa inikwe amandla, ipleyiti yokufudumala ivelisa ubushushu, idlulisele emanzini ngaphakathi, iphakamisa ukushisa kwayo. Ngokwenza, ukuqinisekisa ukuba ubushushu bamanzi buhlangabezana neemfuno zenkqubo, ngokuqhelekileyo bufudumala ngaphambi kokuba bongeze izinto kwaye baxhotyiswe ngenzwa yokushisa ukulinganisa ngokuthe ngqo ubushushu bamanzi. Ngexesha lokusebenza, isitya siphantsi koxinzelelo oluphezulu kwaye sitywinwe, ngoko ubushushu bamanzi bunokulinganiswa kuphela kwaye bulawulwe kusetyenziswa isilawuli sobushushu sedijithali esikrelekrele. Izinto zokulinganisa ubushushu azikwazi ukulinganisa ngokuthe ngqo ubushushu bolwelo olukwisikhongozeli, kodwa ngokungathanga ngqo. Ngoko ke, ukukhethwa kunye nokufakwa kwezi zinto kufuneka kulwele ukunciphisa iimpazamo zokulinganisa kunye nokulawula i-lags. Inkqubo yoxinzelelo iqulethe i-pressure transmitter, isixhobo sokulawula uxinzelelo, i-booster pump, i-valve manual, kunye ne-pneumatic valve. Umsebenzi wayo oyintloko kukubona uxinzelelo ngaphakathi kwesitya esitywiniweyo, ukuguqula ixabiso loxinzelelo kwi-standard 4-20 mA signal, kwaye uyidlulisele kwigalelo lesignali yesixhobo sokulawula uxinzelelo.
Isixhobo sokulawula uxinzelelo yinto ephambili yokulawula inkqubo yoxinzelelo. Ifumana isignali yoxinzelelo kwi-transmitter yoxinzelelo kwaye ilawula imveliso ngokusekelwe kwisignali yoxinzelelo efunyenweyo.
Isiphumo somqondiso kwisixhobo sokulawula uxinzelelo silawula indibano ye-booster, eyandisa uxinzelelo ngaphakathi kwesitya esitywiniweyo.
Indibano ye-booster yinto enzima kwaye ibaluleke kakhulu, equka i-valve ye-solenoid kunye nempompo yokunyusa. Ipompo ye-booster ngokuqhubekayo ifaka amanzi kwisitya esivaliweyo, inyusa uxinzelelo lwangaphakathi ide ifikelele kwixabiso loxinzelelo olubekiwe.
Xa uxinzelelo lufikelela kwixabiso elibekiweyo loxinzelelo, ipompo ye-booster iyayeka, inkqubo ingena kwindawo evaliweyo, uxinzelelo oluqhubekayo, kwaye i-timer iqala. Ngethuba le nkqubo yoxinzelelo oluqhubekayo, inkqubo ihlawula ngokuzenzekelayo ukuhla koxinzelelo, ukugcina uxinzelelo oluzinzileyo ngaphakathi koluhlu oluncinci. Xa ixesha loxinzelelo oluqhubekayo lwenkqubo luphela, isixhobo sokulawula uxinzelelo sithumela isignali yokunciphisa uxinzelelo, ukulawula i-valve yokunceda i-pneumatic ukuba isebenze, ivumela amanzi kwisitya esivaliweyo ukuba abaleke, kunye noxinzelelo olungaphakathi kwisitya ukuba luhle. Inkqubo yokukhusela ibandakanya ukuphakamisa, ukufudumeza, kunye nokukhusela uxinzelelo.
