Nzira yekudzora sei kutonhora kweiyo induction melting furnace?

Automatic tembiricha kutonga kwe kudonhedzwa kunyorera vira-inoreva kuvhura kana kudzima moto unodziya sosi simba rinopihwa muchoto zvinoenderana nekutsauka kwetembiricha yechoto kune yakapihwa tembiricha, kana kuramba uchichinja saizi yesimba rinopisa, kuitira kuti tembiricha yechoto igadzikane uye ine kupihwa tembiricha range Kusangana nezvinodiwa zvekupisa kurapwa maitiro.

Kune maviri-chinzvimbo, matatu-chinzvimbo, akaenzana, proportional integral, nezvimwewo, inowanzoshandiswa mitemo mitemo ye otomatiki kudzora kupisa kupisa tembiricha.

1. Proportional kugadzirisa (P kugadzirisa) -chiratidzo chekubuda (M) chemutongi chinopindirana nekupinda kwekutsauka (e). zvinova:

M=ke

Mune fomula: K–proportional coefficient, pane hukama hwakaenzanirana panguva ipi neipi pakati pekupinza uye kubuda kweiyo proportional regulator, saka kana tembiricha yechoto ichichinja ichienzanirana nechiyero chekugadzirisa, tembiricha yevira haigone kuwedzerwa kuKutsauka. pane yakapihwa kukosha inonzi “static error”

2. Proportional integral (PI) kugadzirisa-Kuitira kuti “static kusiyana”, wedzera zvakakosha (I) kugadzirisa zvakakosha mukuenzaniswa kwekugadzirisa. Kugadziriswa kunoreva kuti chiratidzo chinobuda chemutongi uye kutsauka kunowedzera nenguva, kusvikira kutsauka kwabviswa. Iko hakuna chiratidzo chekubuda, saka kusanganiswa kwekuenzanisa kwekugadzirisa uye kugadzirisa kwakakosha kunogona kubvisa “static musiyano” inonzi proportional integral adjustment.

3. Kugadziriswa-nzvimbo mbiri-kune zvikamu zviviri chete: pa uye kure. Kana tembiricha yevira yakaderera pane yakatarwa kukosha, iyo actuator yakazaruka zvizere; kana tembiricha yevira yakakwira kupfuura kukosha kweseti, iyo actuator yakavharwa zvizere. (Actuator anowanzo shandisa macontactor)

4. Kugadziriswa kwetatu-nzvimbo-ine mbiri yakapihwa kukosha kwepamusoro uye yakaderera muganho, kana tembiricha yevira yakadzikira pane yakapihwa kukosha kweiyo yakaderera muganho, mudziyo wekuvaraidza unovhurwa zvizere; apo kutonhora kwechoto kuri pakati pehupi hupi hupi hwemuganhu wepamusoro uye muganhu wakaderera, actuator inovhurwa zvishoma; Kana tembiricha yechoto ichidarika muganho wepamusoro wakapihwa kukosha, iyo actuator yakavharwa zvizere. (Semuyenzaniso, kana tubular heater iri chinhu chekudziya, matatu-nzvimbo inogadziriswa inogona kushandiswa kuona mutsauko pakati pekudziya uye kubata simba)
