este un \u201egardian\u201d esen\u021bial pentru compresorul frigiderului, congelatorului sau r\u0103citorului de vinuri. Dac\u0103 aparatul face clicuri dar nu porne\u0219te, sau compresorul este fierbinte la atingere, un releu QP2 defect este cel mai probabil vinovat. Acest ghid ofer\u0103 o analiz\u0103 tehnic\u0103 aprofundat\u0103 a<\/b> Fi\u0219ei tehnice a seriei QP2.<\/p>\n

\n
pentru a v\u0103 ajuta s\u0103 selecta\u021bi \u00eenlocuitorul exact pe baza rezisten\u021bei, pinilor \u0219i cerin\u021belor de putere.<\/h2>\n
1. \u0218tiin\u021ba din spatele demaroarelor PTC.<\/p>\n
Un demaror PTC utilizeaz\u0103 un disc ceramic care are rezisten\u021b\u0103 sc\u0103zut\u0103 c\u00e2nd este rece. La pornire, permite un curent ridicat s\u0103 circule prin \u00eenf\u0103\u0219urarea de pornire a compresorului. Pe m\u0103sur\u0103 ce se \u00eenc\u0103lze\u0219te, rezisten\u021ba sa cre\u0219te drastic (aproape instantaneu), \u201edeconect\u00e2nd\u201d efectiv \u00eenf\u0103\u0219urarea de pornire odat\u0103 ce motorul atinge viteza.<\/h2>\n
2. Specifica\u021bii tehnice: Tabelul rezisten\u021belor pentru seria QP2<\/p>\n\n
<\/figure>\n\n
Not\u0103:<\/strong>\u00a0\u201cSelectarea rezisten\u021bei gre\u0219ite poate duce la un \u201dCiclu scurt\u201d sau la o defec\u021biune complet\u0103 la pornire. Utiliza\u021bi un multimetru pentru a verifica piesa actual\u0103 \u00een raport\u00a0higher<\/strong>\u00a0ro_ro.<\/p>\n
dec\u00e2t intervalele enumerate mai sus sau un \u201eCircuit Deschis\u201d (ohmi infinit).<\/h2>\n
\u00a0<\/p>\n
3. Criterii Critice de Selec\u021bie (Verificarea \u00een 3 Puncte)<\/h3>\n
A. Valoarea Ohmic\u0103 (Cea Mai Important\u0103)\u00a0De obicei, rezisten\u021ba (\u03a9) trebuie s\u0103 corespund\u0103 cu piesa original\u0103. Un<\/strong>\u00a0QP2-4.7nu poate fi \u00eenlocuit cu un \u200b<\/strong>QP2-22.\u00a0<\/p>\n
\u200b.<\/p>\n
Dac\u0103 rezisten\u021ba este prea mare, compresorul nu va primi suficient \u201eimpuls\u201d pentru a porni.<\/h3>\n
B. Configura\u021bia Pinilor<\/p>\n
\n
Seria QP2 este disponibil\u0103 \u00een:<\/strong>\u00a0ro_ro.<\/li>\n
Configura\u021bie standard.<\/strong>\u00a02 pini \/ 3 pini:\u00a0Adesea utilizat atunci c\u00e2nd<\/strong>\u00a0un condensator de func\u021bionare.

Asigura\u021bi-v\u0103 c\u0103 piesa de schimb are acela\u0219i num\u0103r de conectori tip furc\u0103 \u00een acelea\u0219i pozi\u021bii.<\/h3>\n
C. Dimensiunea fizic\u0103 a carcasei.<\/p>\n
\n
De\u0219i majoritatea unit\u0103\u021bilor QP2 sunt standard, verifica\u021bi \u00eentotdeauna diametrul \u0219techerului \u0219i distan\u021ba dintre pini pentru a v\u0103 asigura c\u0103 se potrive\u0219te pe conectorul cu trei terminale de pe partea lateral\u0103 a compresorului.<\/h2>\n
\n
4. Depanare: Cum s\u0103 v\u0103 da\u021bi seama dac\u0103 PTC-ul dumneavoastr\u0103 este defect<\/strong>\u00a0Testul prin scuturare:.<\/li>\n
Scoate\u021bi releul \u0219i scutura\u021bi-l l\u00e2ng\u0103 ureche. Dac\u0103 auzi\u021bi un zgomot ca de cioburi de sticl\u0103 (zdr\u0103ng\u0103nit), discul ceramic intern s-a spart.<\/strong>\u00a0ro_ro.<\/li>\n
M\u0103sura\u021bi cele dou\u0103 g\u0103uri unde intr\u0103 pinii compresorului. Dac\u0103 afi\u0219eaz\u0103 \u201eOL\u201d (Dep\u0103\u0219ire Limit\u0103), circuitul este \u00eentrerupt.<\/strong>\u00a0Inspec\u021bie vizual\u0103:.<\/li>\n<\/ol>\n

C\u0103uta\u021bi urme de arsur\u0103 sau un miros de \u201ep\u00e2ine ars\u0103\u201d l\u00e2ng\u0103 borne.<\/h2>\n
\u00a0<\/p>\n
5. \u00centreb\u0103ri frecvente (FAQ)<\/h3>\n
Cum \u0219tiu ce versiune de pini am nevoie?\u00a0Verifica\u021bi cablajul original. Dac\u0103 ave\u021bi un fir care se conecteaz\u0103 la un condensator \u00eenainte de releu, probabil ave\u021bi nevoie de o<\/strong>\u00a0versiune cu 2 pini sau 3 pini.\u00a0<\/p>\n
If only one wire comes from the thermostat, a\u00a0Dac\u0103 doar un fir vine de la termostat, o<\/strong>\u00a0versiune cu 1 pin.<\/p>\n
este standard.<\/h3>\n
De\u0219i un kit de pornire grea (combina\u021bie releu + condensator) poate ajuta un compresor vechi, este \u00eentotdeauna mai sigur s\u0103 \u00eenlocui\u021bi mai \u00eent\u00e2i releul\u00a0QP2<\/strong>\u00a0specificat de produc\u0103torul original (OEM), pentru a evita solicitarea inutil\u0103 a \u00eenf\u0103\u0219ur\u0103rilor motorului.<\/p>\n
Func\u021bioneaz\u0103 QP2-4.7 pentru toate compresoarele de 1\/4 CP?<\/h3>\n
\u00cen general, da. Majoritatea compresoarelor de la 1\/4 CP la 1\/3 CP utilizeaz\u0103\u00a0rezisten\u021ba de 4,7 \u03a9,<\/strong>\u00a0dar verifica\u021bi \u00eentotdeauna cu eticheta de pe carcasa compresorului.<\/p>\n
Sfat de \u00eentre\u021binere profesional\u0103<\/h3>\n
Dac\u0103 releul dvs. PTC s-a ars, este foarte recomandat s\u0103 verifica\u021bi \u0219i\u00a0Protectorul de suprasarcin\u0103<\/strong>\u00a0(componenta circular\u0103 mic\u0103 fixat\u0103 l\u00e2ng\u0103 releu). Aceste dou\u0103 piese cedeaz\u0103 adesea \u00eempreun\u0103 din cauza supratensiunilor sau a bloc\u0103rii compresorului.<\/p>\n\n
