K19 pūoko pehanga wahie 2897690 mo nga taputapu miihini diesel Cummins

1. Semiconductor varistor type intake pressure sensor.

(1) Te maataapono ine o te hikohiko piezoresistive pūoko piezoresistive Ka whakamahia e te semiconductor piezoresistive pressure sensor te painga piezoresistive o te semiconductor ki te huri i te pehanga ki te tohu ngaohiko e rite ana, a ka whakaatuhia tona kaupapa i te Whakaahua 8-21.

Ko te ine riaka Semiconductor he momo huānga tairongo ka huri te uara parenga ina toia, pehia ranei. Ka honoa nga riipene riipene ki te diaphragm silicon ka hono ki te hanga piriti Wheston. I te wa e paheke ana te diaphragm silicon, ka toia, ka pehia ranei ia ine riaka, ka huri tona parenga, ka whai hua ngaohiko rite te piriti.

(2) Te hanganga o te piezoresistive intake pressure sensor Ko te hanganga o te semiconductor piezoresistive intake pressure sensor e whakaatuhia ana i te Whakaahua 8-22. He diaphragm silicon i roto i te huānga huringa pēhanga o te pūoko, me te deformation kōpeketanga o te diaphragm silicon ka puta tohu ngaohiko hāngai. Ko tetahi taha o te diaphragm silicon he korehau, ko tetahi taha ka whakauruhia ki te pehanga paipa whakauru. Ka huri te pehanga o te putorino whakauru, ka rereke te ahua o te diaphragm silicon, ka puta he tohu ngaohiko e rite ana ki te pehanga whakauru. Ko te nui ake o te pehanga whakauru, ka nui ake te whakarereketanga o te diaphragm silicon me te nui ake o te pehanga putanga o te puoro.

Ko te ahua o te momo semiconductor varistor intake pipe pressure sensor he pai nga painga o te raina pai, te iti o te hanganga, te tino tika me nga ahuatanga whakautu pai.

1) Momo kitenga auau: ka huri te auau oscillation o te ara iahiko oscillation ki te uara kaha o te huānga tairongo pehanga, a, i muri i te whakatikatika me te whakakaha, ka puta te tohu pupuhi me te auau e rite ana ki te pehanga.

2) Momo rapunga ngaohiko: ko te huringa o te uara punga o te huānga tairongo pehanga ka whakarereketia e te ngaru kawe me te ara iahiko whakakaha AC, ka whakahekehia e te ara iahiko puhoi, katahi ka tātarihia e te iahiko tātari ki te tohu ngaohiko whakaputa e pa ana ki te huringa pehanga.
