Tarisa vharafu CV12-20 yehombe inoyerera hydraulic system

Misiyano pakati pekumanikidza sensors, relays uye switch

1. Isu tose tinowanzonzwa nezve kudzvinyirira sensor, pressure relay uye pressure switch. Akabatana here? Chii chakasiyana? Inotevera sumo ine udzame yevatatu. Sensor yepressure inoumbwa ne-pressure-sensitive element uye dunhu rekushandura, iro rinogadzira zvishoma kuchinjwa ikozvino kana kubudiswa kwemagetsi pachinhu chinonzwa-chinonzwika nekushandisa kudzvinyirira kwepakati yakayerwa. Sensors kazhinji inoda kushandiswa pamwe chete neyekunze amplifier maseketi kupedzisa maitiro kubva pakudzvanywa kwekuona kudzora uye kuratidza. Nekuda kwekuti iyo yekumanikidza sensor ndiyo yekutanga chikamu, chiratidzo chinodzoserwa nekudzvanywa sensor chinoda kugadziriswa, kuongororwa, kuchengetwa uye kudzorwa nechiyero uye chekutonga system, izvo zvinoita kuti maindasitiri otomatiki emidziyo uye enjiniya oparesheni kutonga kuve nehungwaru.

2. The pressure relay is a sign conversion element ye electro-hydraulic switch inoshandisa mvura pressure kuvhura nekuvhara macontacts emagetsi. Inoshandiswa kutumira masaini emagetsi kudzora zviito zvezvikamu zvemagetsi kana system yekumanikidza inosvika pakumanikidzwa kweiyo relay, kuitira kuti uone kurodha kana kuburitsa kutonga kwepombi, kutevedzana kwezviito zveaiti, kuchengetedza kuchengetedza. uye interlock of the system, etc. Inosanganisira zvikamu zviviri: kumanikidzika-kudzingwa kwekushandura chikamu uye microswitch. Zvinoenderana nemhando dzezvimiro zvekumanikidza-kuchinjisa kutendeuka zvikamu, kune mana marudzi: plunger type, spring type, diaphragm type uye bellows type. Pakati pavo, iyo plunger chimiro chakakamurwa kuva imwechete plunger mhando uye mbiri plunger mhando. Iyo imwechete plunger mhando inogona kukamurwa kuita mhando nhatu: plunger, differential plunger uye plunger-lever. Maererano nekubatana, kune imwe chete yekubatana uye kaviri magetsi emagetsi.

3. Shanduko yekumanikidza ishanduko inoshanda iyo inodzima kana kudzima kana yasvika pachiyero chakatarwa maererano nekumanikidza kwakaiswa.

4. Pressure switches uye pressure relays inogona kungobatidzwa kana kudzimwa pasi pesimba rako rakapihwa, rinoshandiswa pakudzora chinzvimbo chiri nyore. Iwo ese anochinja kubuda! Pressure relay inogona kupa akawanda anobuda node kana node mhando pane kudzvanywa switch. Iyo inobuda yekumanikidza sensor inogona kuve analog siginecha kana dhijitari chiratidzo, iyo yakanakira post-kugadzirisa, uye inogona zvakare kuchinjwa kuita yakajairwa transmitter siginecha yekutapurirana kure.
