Kev Sib Piv Kev Ua Haujlwm thiab Kev Xaiv Qhia rau Frascold thiab Bitzer Reciprocating Compressors
Sep 07, 2026
Tsawg-kub tub yees tshuab hauv cov chaw cia txias ua haujlwm nruab nrab ntawm -25℃thiab -40℃evaporating kub xav tau cov cuab yeej hloov chaw zoo heev. Ntau lub tog raj kheej reciprocating compressors los ntawm cov tuam txhab lag luam thoob ntiaj teb xws li Bitzer thiab Frascold tau nthuav dav hauv cov ntawv thov no. Kev ntsuam xyuas lawv lub hnab ntawv ua haujlwm, kev ua haujlwm txias ntawm lub cev, thiab kev tsim kho tshuab sab hauv muab cov lus qhia muaj txiaj ntsig zoo rau cov neeg tsim qauv thiab cov kws tsim khoom tsim khoom.
Cov hnab ntawv ua haujlwm thiab kev tswj xyuas cua sov
Nyob rau hauv qis evaporating kub tswj, tso pa kub kub nce sai heev vim qhov siab compression ratios tshaj 10/1. Bitzer reciprocating tub yees compressor units nquag siv tshwj xeeb lub cev muaj zog txias configurations ib sab Varicool suction gas routing los yog kua txhaj tshuab los tswj thermal stress.
Frascold semi-hermetic qauv suav nrog kev ua kom zoo hauv cov pa hauv nruab nrog thiab siab -kev nqus valve ntws geometries kom txo qis suction superheat nce hauv tsev. Ob txoj hauv kev tiv thaiv cov roj lubricating tawg thiab khaws cov roj viscosity siab tshaj qhov tseem ceeb ntawm kev ua haujlwm hauv kev siv tub yees.
Volumetric Efficiency thiab Valve Mechanics
Volumetric efficiency nyob rau hauv qis -kub daim ntawv thov nyob ntawm hnyav npaum li cas clearance thiab valve dynamic teb. Bitzer reciprocating compressors siv caij nplooj ntoos hlav-loaded nplhaib li qub engineered rau siab tensile lub zog, txo cov roj re-expansion poob thaum lub sij hawm nqus stroke.
Frascold ntiav cov ntaub ntawv hloov pauv hloov pauv tau tsim nrog cov huab hwm coj qis thiab ua kom pom tseeb ntawm cov hlab ntsha tawg, ua rau lub sijhawm teb ceev ceev raws li kev hloov pauv hloov pauv. Ob lub valve configurations muab robust tiv thaiv dynamic kev nyuaj siab, kom ntseeg tau siab volumetric tus me nyuam txawm nyob rau hauv tsawg suction siab tej yam kev mob.
Lubrication Systems thiab Maintenance Protocols
Kev lubrication tsis tu ncua yog qhov tseem ceeb thaum lub sij hawm sib sib zog nqus qis - kub ua haujlwm. Ob Bitzer thiab Frascold multi- lub tog raj kheej qauv muaj qhov zoo- hloov iav roj twj lossis txaws lubrication tshuab nrog cov lim hlau sab hauv.
Thaum ua raws li niaj hnub compressor txij nkawm lossis hloov khoom siv, cov kws tsim khoom yuav tsum txheeb xyuas cov roj sib txawv siab tshaj 0.14 MPa thiab tswj cov roj crankcase kub ntawm 10℃mus rau 15℃saum toj no ambient saturation theem thaum standby. Crankcase rhaub kom zoo interlocks tiv thaiv kua refrigerant migration thaum tawm - mus.
Kev xaiv Summary rau Cold Storage Projects
Rau cov ntawv thov kev lag luam tub yees uas xav tau kev ua haujlwm qis - qhov kub thiab txias, Frascold thiab Bitzer reciprocating compressors muaj qhov tshwj xeeb ntawm kev ua haujlwm ntev. Cov kws ua haujlwm hauv lub cev yuav tsum ntsuas cov kev txwv evaporating, cov yam ntxwv ntawm kev co, thiab lub zog valve thaum xaiv lossis hloov cov khoom siv hauv qhov chaw txias. Kev sib txuam compressor txav ncaj qha mus rau thermal load profiles kom ntev - lub zog efficiency thiab kev cia siab rau kev ua haujlwm.
