Kev sib piv - qhov piv ntawm qhov siab tshaj plaws thiab qis tshaj qhov ua tau ncua sij hawm rau lub transmitter. (Piv txwv li, yog 1, 000 psi transmitter muaj qhov sib piv ntawm 5: 1, ces qhov siab tshaj plaws tau ncua yog 0 mus rau 1, 000 psi thiab qhov qis tshaj plaws tau ncua yog 0 txog 200 psi.)
txhais li cas los ntawm turndown ratio?
Turndown piv feem ntau kuj tseem hu ua rangeability ntawm ib qho cuab yeej. Nws txhais tau tias yog qhov piv ntawm qhov siab tshaj plaws ntawm kev ntsuas mus rau qhov tsawg kawg nkaus rau kev ntsuasNws tau qhia tias yog qhov sib npaug ntawm qhov qis tshaj mus rau qhov siab tshaj plaws.
Koj ua li cas suav qhov piv txwv ntawm lub tshuab xa hluav taws xob siab?
Turndown(TD) lossis Rangeability:
Nws yog qhov kev sib raug zoo ntawm qhov siab tshaj plaws (URL) thiab qhov ntsuas qhov tsawg kawg nkaus (tsawg kawg calibrated ncua). Piv txwv li, lub transmitter ntau yam yog 0-5080 mmH2O thiab yuav siv rau 10: 1, qhia uas transmitter yuav ntsuas 0 mus rau 508 mmH2O. TD=URL / Calibrated Span.
Yuav suav suav li cas?
Turndown Ratio=qhov siab tshaj plaws / qhov tsawg kawg nkaus Piv txwv li, yog tias qhov ntsuas ntsuas tau muaj 50: 1 turndown ratio qhov ntsuas ntsuas muaj peev xwm ua tau raug. ntsuas mus rau 1/50th ntawm qhov siab tshaj plaws ntws.
Koj txhais li cas turndown ratio?
Boiler turndown yog qhov piv ntawm lub boiler qhov siab tshaj plaws thiab qhov tsawg kawg nkaus tso zis. Nyob ntawm tus qauv tsim, nws yuav muaj qhov sib piv ntawm 5: 1 thiab 10: 1 lossis ntau dua. A 5: 1 turndown txhais tau hais tias lub boiler qhov tsawg kawg nkaus kev khiav hauj lwm load yog 20% ntawm lub boiler lub peev xwm (100% muaj peev xwm muab faib los ntawm 5).
