Mfundo yogwirira ntchito ya excavator pressure sensor ndi switch switch

Excavator Pressure Sensor

Komatsu pressure sensor ikuwonetsedwa mu Chithunzi 4-20.Mafuta akalowa kuchokera kumayendedwe oponderezedwa ndipo kukakamiza kumayikidwa pa diaphragm ya chowunikira chamafuta, diaphragm imapindika ndikupunduka.Chigawo choyezera chimayikidwa mbali ina ya diaphragm, ndipo kukana kwa gawolo kumasintha, kusintha kupindika kwa diaphragm kukhala voteji yotulutsa, yomwe imatumizidwa ku voltage amplifier, yomwe imakulitsa mphamvu yamagetsi. kenako amaperekedwa kwa electro-mechanical controller (kompyuta board).

Kuthamanga kwamphamvu kwa sensa, kumapangitsa kuti magetsi atuluke;molingana ndi kupsinjika kwamanjenje, sensa yothamanga nthawi zambiri imagawidwa m'mitundu iwiri: sensa yapamwamba komanso sensor yotsika.Sensor yothamanga kwambiri imagwiritsidwa ntchito kuyeza kutulutsa kwamphamvu komanso kuthamanga kwa pampu yayikulu.Masensa otsika kwambiri amagwiritsidwa ntchito mumayendedwe oyendetsa oyendetsa ndi machitidwe obwerera mafuta.

Wamba voteji ntchito mphamvu masensa ndi 5V, 9V, 24V, etc. (chisamaliro chapadera ayenera kuperekedwa kusiyanitsa pamene m'malo).Nthawi zambiri, masensa amphamvu pamakina omwewo amagwira ntchito pamagetsi omwewo.Mphamvu yogwira ntchito ya sensor pressure ndi yaying'ono kwambiri, ndipo imayendetsedwa mwachindunji ndi bolodi la makompyuta.

Kusintha kwamphamvu kukuwonetsedwa mu Chithunzi 4-21.Kusinthana kwamphamvu kumazindikira kupanikizika (pa / kuzimitsa) kwa dera loyendetsa ndege ndikutumiza ku bolodi la makompyuta.Pali mitundu iwiri yosinthira kuthamanga: nthawi zambiri-yoyatsa komanso yozimitsa, kutengera ngati dera limalumikizidwa pomwe palibe kukakamiza padoko.Mitundu yosiyanasiyana ndi magawo osiyanasiyana osinthira kuthamanga amakhala ndi zovuta zoyambira komanso kuyambiranso kukakamiza.Nthawi zambiri, zosinthira zosinthira pazida zozungulira komanso zogwirira ntchito zimakhala ndi mphamvu zocheperako, pomwe zosinthira zokakamiza kuyenda zimakhala ndi ziwopsezo zokwera kwambiri.
