Limit Switch Bhokisi: A Comprehensive Guide
Mumazuva ano maindasitiri otomatiki uye mavharuvhu ekudzora masisitimu, kuve nechokwadi chekutarisa chaiko kwenzvimbo yevharuvhu kwakakosha. Amuganhu chinja bhokisiinoita basa rakakosha mukuita uku nekupa mhinduro yakavimbika kune vashandisi uye masystem ekudzora. Zvingave mumapaipi eoiri negasi, zvigadziriso zvekuchenesa mvura, kana maindasitiri emakemikari, mudziyo unova nechokwadi chekuti mavharuvhu akachengeteka, akarurama, uye anogona kurongeka.
Ichi chinyorwa chinopa tsananguro yakadzama yekuti chii chinonzi muganhu switch bhokisi, mashandiro ainoita, zvikamu zvaro zvikuru, mhando dzakasiyana, uye mashandisirwo mumaindasitiri akasiyana siyana. Pakupera, iwe uchave nekunzwisisa kwakajeka kwechikonzero nei ichi chishandiso chakakosha mukutonga kwemaitiro.
Chii chinonzi Limit Switch Bhokisi?
A limit switch box is a compact device yakaiswa pamusoro pema actuators kana mavharuvhu. Basa rayo guru nderokuratidza kana valve iri panzvimbo yakazaruka kana yakavharwa. Iyo inoshandura mafambiro emagetsi evharuvhu hunde kana actuator shaft kuita chiratidzo chemagetsi chinogona kutumirwa kune yakagoverwa control system (DCS), programmable logic controller (PLC), kana zviratidzo zvinoonekwa zvevanoshandisa zvirimwa.
Mumashoko akajeka, anoita se "maziso" evhavha system. Ipo iyo actuator ichifambisa vharuvhu, iyo yekumisikidza switch bhokisi inoita kuti vashandisi vazive chaizvo pakamira valve.
Zvinangwa Zvikuru
- Valve Position Feedback- Inopa masaini emagetsi kudzora makamuri nezvekuti vharafu yakavhurika kana yakavharwa.
- Kuvimbiswa Kwekuchengeteka-Inodzivirira mashandiro asiri iwo anogona kukonzera kuvuza, kupera, kana tsaona.
- Automation Integration-Inogonesa kubatana nePLCs uye SCADA masisitimu e automated process control.
- Visual Indication-Mazhinji mabhokisi anosanganisira mechanical zviratidzo (semuenzaniso, tsvuku/girinhi miseve kana domes) kuitira nyore pa-saiti yekutarisa.
Bhokisi reLimit Switch rinoshanda sei?
Iyo yekushanda musimboti wemuganho switch bhokisi iri nyore, asi kuvimbika kwayo kunoita kuti ive yakakosha.
- Mechanical Movement- Kana actuator ichivhura kana kuvhara vharafu, shaft kana dzinde rinotenderera kana kufamba zvine mutsetse.
- Cam Mechanism-Mukati meiyo yekumisikidza bhokisi bhokisi, cam yakasungirirwa pane shaft inotenderera zvinoenderana.
- Chinja Activation-Iyo cam inobata nemicro-swichi, padhuze sensors, kana magineti sensors mukati mebhokisi.
- Signal Transmission- Kana yangoitwa, idzi switch dzinotumira chiratidzo chemagetsi kuratidza nzvimbo yevharuvhu (yakavhurika / yakavharwa kana yepakati nyika).
- Mhinduro kune Kudzora System-Chiratidzo chinofambiswa kune kudzora mapaneru, SCADA, kana emunharaunda kuratidza.
Muenzaniso Usina Kuoma
- Vhuru yakavhurika zvizere → Cam inokonzeresa "kuvhurika" switch → Green chiratidzo chakatumirwa.
- Vhuru yakavharwa zvizere → Cam inokonzeresa "yakavharwa" switch → Chiratidzo chitsvuku chakatumirwa.
- Vhuru mushanduko → Hapana chiratidzo chechokwadi, kana mumhando yepamusoro, mhinduro yeanalogi inoratidza chaiyo chinzvimbo.
