Nres Circuit Court (BK)

1 Txheej txheem cej luam

Brake circuits yog categorized ua ob hom:tswj tam sim nothiabresistive voltage divider-tswj. Ob leeg suav nrogtsav circuitsthiabtiv tauj cov lus qhia circuits.

1.1 Tam sim no-Controlled Brake Circuit Court

Qauv:
- Tsav Circuit: Powered los ntawm #79 los yog S420, tswj los ntawm #LB contactor.
- Cov lus qhia Circuit: Nres kev sib cuag teeb liab (qhib / kaw) xa ncaj qha rau W1 / R1 boards.
Kev ua haujlwm:
1. #LB contactor kaw → Control unit (W1/E1) qhib.
2. Control unit outputs nres voltage → Nres qhib.
3. Cov lus tawm tswv yim xa cov xwm txheej armature.

1.2 Resistive Voltage Divider-Controlled Nres Circuit Court

Qauv:
- Tsav Circuit: suav nrog voltage-dividing resistors thiab tawm tswv yim tiv tauj.
- Cov lus qhia Circuit: Saib xyuas armature txoj hauj lwm ntawm NC / TSIS muaj kev sib cuag.
Kev ua haujlwm:
1. Nres Kaw: NC tiv tauj luv-circuit resistors → Puv voltage thov.
2. Nres qhib: Armature txav → NC hu qhib → Resistors txo qhov hluav taws xob rau qib txij nkawm.
3. Cov lus pom zoo ntxiv: Tsis muaj kev tiv tauj ntxiv kom paub meej tias nres nres.

Ntsiab Lus:

RauZPML-A traction tshuab, nres qhov sib txawv ntawm kev hloov pauv ncaj qha cuam tshuam rau kev mus los ntawm armature (zoo tshaj: ~ 2mm).

2 Cov kauj ruam daws teeb meem dav dav

2.1 Nres Action Failures

Cov tsos mob:

Nres tsis qhib / kaw (ib leeg lossis ob sab).
Nco tseg: Ua tiav nres nres yuav ua rau lub tsheb slippage (kev nyab xeeb tseem ceeb).

Diagnostic cov kauj ruam:

Tshawb xyuas Voltage:
- Txheeb xyuas qhov ntsuas hluav taws xob tag nrho thaum lub sijhawm qhib thiab kho qhov hluav taws xob tom qab.
- Siv multimeter los ntsuas coil voltage (piv txwv li, 110V rau #79).
Tshawb xyuas kev sib cuag:
- Kho kev sib cuag kev sib raug zoo (chaw rau kev tswj tam sim no; nyob ze rau kev mus ncig kawg rau kev tiv thaiv kev tiv thaiv).
Mechanical Checks:
- Lubricate txuas; xyuas kom tsis muaj kev cuam tshuam hauv txoj kev armature.
- Khonres nres(0.2-0.5mm) thiablub caij nplooj ntoos hlav torquenruj.

2.2 Cov Lus Qhia Tsis Txaus

Cov tsos mob:

Nres ua haujlwm ib txwm, tab sis P1 pawg thawj coj saib pom cov lej ntsig txog nres (piv txwv li, "E30").

Diagnostic cov kauj ruam:

Hloov cov lus tawm tswv yim: Kuaj nrog cov khoom paub zoo.
Kho qhov chaw tiv tauj:
- Rau kev tiv thaiv kev tiv thaiv: Kho cov neeg nyob ze ntawm armature mus ncig kawg.
Tshawb xyuas Cov Hluav Taws Xob Hluav Taws Xob:
- Tshawb xyuas txuas ntxiv los ntawm kev sib cuag mus rau W1 / R1 boards.

2.3 Kev ua yuam kev sib xyaw

Cov tsos mob:

Nres ua haujlwm tsis ua haujlwm + cov lej txhaum.

Kev daws:

Ua tag nrho cov kev hloov nres siv cov cuab yeej xws liZPML-A Nres Calibration Device.

3 Kev Ua Phem & Kev daws teeb meem

3.1 Nres tsis qhib

Ua rau	Kev daws
Kev tsis zoo ntawm Coil Voltage	Kos lub rooj tsav xwm tswj cov zis (W1 / E1) thiab kev ruaj ntseg ntawm kev sib txuas.
Kev sib cuag tsis raug	Kho qhov chaw tiv tauj (ua raws li ZPML-A cov lus qhia).
Mechanical Thaiv	Ntxuav/lubricate nres caj npab; kho qhov sib txawv thiab lub caij nplooj ntoos hlav nro.

3.2 Tsis txaus Braking Torque

Ua rau	Kev daws
Hnav Nres Nres Linings	Hloov cov ntaub ntawv (piv txwv li, ZPML-A cov ntaub ntawv sib txhuam).
Loose Torque Caij nplooj ntoos hlav	Kho lub caij nplooj ntoos hlav nro rau specifications.
Cov Nto Ntog	Ntxuav cov brakes/pads; tshem cov roj / roj.

4. Daim duab

Daim duab: Brake Circuit Schematics

Tswj tam sim no: Simplified topology nrog kev ywj pheej tsav / kev tawm tswv yim.
Resistive Control: Voltage-dividing resistors thiab txhim kho kev tawm tswv yim tiv tauj.

Cov ntaub ntawv sau tseg:
Phau ntawv qhia no ua raws li Mitsubishi elevator qauv. Ib txwm ua raws li cov txheej txheem kev nyab xeeb thiab sab laj cov ntawv qhia kev paub txog cov qauv tshwj xeeb.
