1. Vim li cas lub tshuab cua compressor thiaj yuav tsum khiav tas li tsawg kawg 5 feeb thiab nres tsawg kawg 3 feeb tom qab kaw ua ntej rov pib dua?
Tom qab kaw lub tshuab, nres tsawg kawg yog 3 feeb ua ntej rov pib dua kom tshem tawm qhov sib txawv ntawm lub zog ntawm lub compressor inlet thiab lub qhov tso pa tawm. Vim tias thaum qhov sib txawv ntawm lub zog loj, lub zog pib ntawm lub cev muaj zog yuav nce ntxiv, ua rau tam sim no nce mus rau qee qib, lub cuab yeej tiv thaiv yuav qhib, thiab lub compressor tsis tuaj yeem txuas ntxiv khiav.
2. Kev lees paub qhov chaw ntawm lub tshuab cua txias uas muaj fluorine
Feem ntau cov tub yees tuaj yeem ntxiv rau hauv peb qhov chaw: condenser, sab cia kua ntawm lub compressor, thiab evaporator.
Thaum ntxiv cov kua rau ntawm qhov chaw cia kua, thaum lub kaw lus pib, cov kua refrigerant yuav cuam tshuam rau lub tog raj kheej tas li, ua rau lub compressor tsim cov kua poob siab, uas ua rau lub compressor puas tsuaj heev. Tib lub sijhawm, tom qab cov kua refrigerant nkag mus rau hauv lub compressor, nws yuav lo rau ntawm qhov kawg, ua rau muaj kev rwb thaiv tsev tam sim ntawd thiab tsis muaj zog tiv taus; ib yam li ntawd, qhov xwm txheej no kuj yuav tshwm sim thaum ntxiv cov kua rau ntawm sab evaporator.
Raws li rau lub condenser, vim nws muaj ntau qhov loj, nws tuaj yeem khaws cia cov khoom txias txaus, thiab yuav tsis muaj qhov tshwm sim tsis zoo thaum pib, thiab qhov ceev ntawm kev sau yog ceev thiab muaj kev nyab xeeb; yog li txoj kev sau cov kua ntawm lub condenser feem ntau yog siv.
3.. Cov hloov pauv cua sov thiab cov thermistors rau kev hloov pauv zaus
Cov hloov pauv cua sov thiab cov thermistors tsis muaj feem cuam tshuam nrog cov xov hlau compressor thiab tsis txuas ncaj qha ua ke hauv series hauv lub compressor circuit.
Cov hloov pauv thermal tswj qhov qhib thiab kaw ntawm lub voj voog tswj compressor los ntawm kev ntsuas qhov kub ntawm lub hau compressor.
Cov thermistors yog cov yam ntxwv kub tsis zoo uas muaj cov teeb liab tawm tswv yim rau lub microprocessor. Ib pawg ntawm cov lus qhia kub thiab tsis kam tau muab tso ua ntej hauv lub microprocessor. Txhua tus nqi tsis kam ntsuas tuaj yeem cuam tshuam qhov kub sib xws hauv lub microcomputer. Thaum kawg, qhov cuam tshuam tswj kub tau ua tiav.
4. Lub cev muaj zog winding kub
Cov xwm txheej ua haujlwm yuav tsum qis dua 127 ° C ntawm qhov siab tshaj plaws.
Txoj kev ntsuas: Hauv 3 vib nas this tom qab lub compressor nres, siv Wheatstone choj lossis digital ohmmeter los ntsuas qhov tsis kam ntawm lub winding tseem ceeb, thiab tom qab ntawd xam raws li cov qauv hauv qab no:
Qhov kub ntawm qhov cua t℃ = [R2(T1+234.5)/R1]-234.5
R2: ntsuas qhov tsis kam; R1: qhov tsis kam ntawm winding thaum txias; T1: qhov kub ntawm lub cev muaj zog txias
Yog tias qhov kub ntawm qhov winding tshaj qhov siv, cov teeb meem hauv qab no yuav tshwm sim:
Qhov ceev ntawm cov xov hlau enameled winding yog accelerated (lub cev muaj zog hlawv);
Qhov ceev ntawm cov khoom siv rwb thaiv tsev thiab daim ntawv rwb thaiv tsev yog nrawm dua (lub neej rwb thaiv tsev yog ib nrab rau txhua 10 ℃ nce hauv qhov kub);
Kev puas tsuaj ntawm cov roj vim yog overheating (kev ua haujlwm ntawm lubrication txo qis)
