Excavator Pressure Sensor
Iyo Komatsu pressure sensor inoratidzwa muMufananidzo 4-20.Kana oiri ichipinda kubva mukudzvanywa inlet uye kudzvanywa kunoshandiswa kune diaphragm yemafuta pressure detector, iyo diaphragm inokotama uye deform.Chiyero chechiyero chakaiswa kune rumwe rutivi rwe diaphragm, uye kukosha kwekupikisa kwechiyero chekuyera kunoshanduka, kushandura curvature ye diaphragm kuita magetsi anobuda, ayo anotumirwa kune voltage amplifier, iyo inowedzera kuwedzera magetsi, ayo ari. yobva yatumirwa kune electro-mechanical controller (computer board).
Mufananidzo 4-20
Iyo yakanyanya kudzvanywa pane sensor, iyo yakakwira yakabuda voltage;zvinoenderana nekumanikidzwa kwekunzwa, iyo yekumanikidza sensor inowanzo kupatsanurwa kuva marudzi maviri: high pressure sensor uye low pressure sensor.Iyo yakanyanya kudzvanywa sensor inoshandiswa kuyera yakabuda kudzvanywa uye mutoro wekumanikidza wepombi huru.Low pressure sensors inoshandiswa mupilot control system uye mafuta ekudzosa masisitimu.
Iwo akajairika kushanda voltages of pressure sensors i5V, 9V, 24V, nezvimwewo (kutarisisa kunofanirwa kubhadharwa kusiyanisa pakutsiva).Kazhinji, ma sensors ekumanikidza pamushini mumwe chete anoshanda pamhepo yakafanana.Iko kushanda ikozvino kwekumanikidza sensor idiki kwazvo, uye inofambiswa zvakananga nebhodhi rekombuta.
Excavator Pressure Switch
Iyo yekumanikidza switch inoratidzwa muMufananidzo 4-21.Iyo yekumanikidza switch inoona iyo yekumanikidza mamiriro (pa/kudzima) yedunhu remutyairi uye anoiendesa kubhodhi rekombuta.Kune marudzi maviri ekumanikidza switch: kazhinji-pa uye kazhinji-kudzima, zvichienderana nekuti dunhu rakabatana kana pasina kudzvanywa pachiteshi.Mamodheru akasiyana uye zvikamu zvakasiyana zvekudzvanyirira switch zvine akasiyana actuation kumanikidza uye kudzoreredza kumanikidza.Kazhinji, machinjiro ekutenderera uye emidziyo yebasa ane yakaderera actuation kumanikidzwa, nepo kudzvanywa kwekuchinja kwekufamba kune yakakwirira actuation pressure.
