Yuav ua li cas yog lub geared lub cev muaj zog overloaded?

Kev daws rau Geared Motor Overload

Thaum lub cev muaj zog yog overloaded, txhais tau tias lub cev muaj zog tuaj yeem tig tau tab sis qhov kev khiav hauj lwm tam sim no tshaj tus nqi ntsuas, yuav tsum tau ua ntau yam kev ntsuas los daws qhov teeb meem. Cov hauv qab no yog kev tshuaj xyuas ntawm qhov ua rau geared motor overload thiab cov kev daws teeb meem sib xws:

I. Kev soj ntsuam ntawm qhov ua rau muaj overload

** Ntau yam khoom siv Load:**

Cov yam ntxwv tseem ceeb: Lub cev muaj zog overheats; lub overload tuaj yeem tshawb pom los ntawm kev nyeem cov haujlwm tam sim no ntawm lub vijtsam zaub.

Kev daws: Txheeb xyuas seb qhov sib kis sib kis tuaj yeem tsim nyog ntxiv kom txo cov load ntawm lub geared lub cev muaj zog ncej. Yog tias qhov sib kis tsis tuaj yeem nce ntxiv, xav txog kev hloov nws nrog lub cev muaj zog nrog lub peev xwm loj dua.

** Peb -Phase Voltage Imbalance:**

Yam ntxwv: Ua rau muaj kev khiav hauj lwm ntau dhau ntawm ib theem, ua rau overload tripping thiab tsis sib xws lub cev muaj zog cua sov.

Kev daws: Ua ntej, xyuas seb peb -theem voltage ntawm lub cev muaj zog yog sib npaug. Yog tias tsis sib npaug, ces xyuas seb peb -theem voltage ntawm lub inverter tso zis yog sib npaug. Yog hais tias lub inverter tso zis voltage kuj tsis sib npaug, qhov teeb meem nyob rau hauv lub inverter nws tus kheej. Yog hais tias lub inverter tso zis voltage yog sib npaug, qhov teeb meem nyob rau hauv lub thaiv ntawm lub inverter thiab lub cev muaj zog. Xyuas tias tag nrho cov ntsia hlau davhlau ya nyob twg yog nruj thiab cov contactor hu tau zoo.

False Trip:

Ua rau: Ib qho txhaum ntawm lub inverter lub sab hauv tam sim no nrhiav kom tau qhov ua rau lub teeb liab siab heev tam sim no, ua rau tripping.

Kev daws: Txheeb xyuas qhov inverter sab hauv qhov ntsuas tam sim no kom paub meej tias qhov txhaum thiab ua qhov tsim nyog kho lossis hloov pauv.

II. Overload Check Method

Xyuas lub cav cua sov:

Yog hais tias lub cev muaj zog kub nce tsis siab, xyuas seb lub inverter qhov hluav taws xob thermal tiv thaiv muaj nuj nqi preset yog tsim nyog. Yog hais tias lub inverter muaj cov npoo ntawm kev nyab xeeb, tus nqi preset ntawm hluav taws xob thermal tiv thaiv muaj nuj nqi yuav tsum tau so.

Yog hais tias lub cev muaj zog kub nce siab dhau lawm, thiab lub overload yog nyob rau hauv qhov qub, nws qhia tau hais tias lub cev muaj zog overloaded thiab yuav tsum tau ua raws li cov kev daws teeb meem rau mechanical overload tau piav saum toj no.

Xyuas peb -theem voltage tshuav nyiaj li cas:

Yog tias peb -theem voltage ntawm lub cev muaj zog tsis sib npaug, kho nws raws li cov kev daws teeb meem rau peb -theem voltage imbalance tau piav qhia saum toj no.

Nkag siab txog kev khiav hauj lwm zaus uas lub Circuit Court breaker mus ncig:

Yog hais tias lub cev muaj zog mus ncig ntawm ib qho kev khiav hauj lwm zaus, nws yuav muaj feem xyuam nrog cov yam ntxwv ntawm qhov zaus ntawd. Kev tsom xam ntxiv ntawm cov yam ntxwv ntawm kev thauj khoom yog xav tau, thiab cov inverter lossis lub cev muaj zog yuav tsum tau hloov kho kom tau raws li qhov yuav tsum tau ua.

III. Lwm yam kev ceev faj

Thaum tuav cov teeb meem overload, xyuas kom meej tias qhov tsis zoo ntawm lub cev muaj zog thiab inverter raug teeb tsa kom raug kom tsis txhob muaj overload los ntawm kev teeb tsa tsis raug.

Tsis tu ncua tswj lub cev muaj zog thiab inverter, tshuaj xyuas qhov nruj ntawm cov xov hlau txuas thiab kev sib cuag ntawm cov contactors, relays, thiab lwm yam khoom siv hluav taws xob kom ntseeg tau tias muaj kev sib txuas hluav taws xob zoo.

Yog tias qhov ua rau overload tsis tuaj yeem txiav txim siab lossis qhov teeb meem tsis tuaj yeem daws tau, hu rau cov neeg ua haujlwm saib xyuas lossis cov chaw tsim khoom pabcuam kev pabcuam.
