. Cov txheej txheem suav kom ntxaws txog kev ntxuav cov nqi

Kev suav cov nqi tu ntawm cov phaj kub hloov pauv yog qhov tseem ceeb, uas feem ntau muaj cov hauv qab no:

1. Cov Nqi Ua Haujlwm Cov Nqi Ua Haujlwm tau tshwm sim thoob plaws hauv cov txheej txheem ntxuav, npog kev tshem tawm, ntxuav, rov ua dua thiab lwm yam txheej txheem.

2.Material Cost Nqi ntawm consumables siv nyob rau hauv tu, nrog rau cov tshuaj ntxuav, dej, hluav taws xob thiab lwm yam khoom siv.

3. Cov Nqi Them Nqi Them Nqi Them Nqi Them Nqi ntawm cov khoom siv tu tshwj xeeb tau txais, xws li siab - rab phom dej siab thiab lub twj tso kua mis tu.

4. Kev Tswj Tus Nqi Them Nqi Them Nqi Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij rau kev ntxuav tu, suav nrog kev tswj hwm qhov project, kev tswj kom zoo thiab kev ua haujlwm cuam tshuam.

5.Profit Reasonable profit margin reserved los ntawm tus neeg muab kev pab tu.

II. Yam tseem ceeb cuam tshuam rau cov nqi

1.Type thiab Severity of Fouling Ntau hom fouling (xws li roj, mineral deposits thiab biofilm) yuav tsum tau sib txawv txoj kev tu thiab tu cov neeg ua hauj. Qhov hnyav dua qhov fouling, qhov siab dua qhov nyuaj tu thiab cov nqi sib xws.

2.Ntawm thev naus laus zis cov nqi sib txawv heev nyob ntawm kev siv thev naus laus zis, suav nrog kev tu tshuaj lom neeg, kev tu tshuab, kev tu ultrasonic, thiab lwm yam. Cov cuab yeej tu tshuab muaj cov cuab yeej yooj yim nrog cov nqi qis, thaum cov tshuaj ntxuav tu thiab cov khoom siv tu ultrasonic tuaj ntawm cov nqi ntau dua.

3. Kev Ua Haujlwm Ib puag ncig Qhov nyuaj ntawm qhov chaw ua haujlwm cuam tshuam rau kev tu kom nyuaj thiab cov sijhawm ua haujlwm. Ib puag ncig uas muaj qhov kub thiab txias, siab siab lossis qhov chaw nqaim yuav thawb cov nqi tu.

4.Geographic Qhov chaw Geographic qhov chaw txiav txim siab cov nqi zog thiab cov khoom siv, thiab cov nqi sib txawv ntawm cov cheeb tsam sib txawv muaj qhov cuam tshuam ncaj qha rau tag nrho cov nqi tu.

III. Xaus

Tus nqi tu ntawm cov phaj kub hloov pauv yog cuam tshuam los ntawm ntau yam, thiab cov xwm txheej tshwj xeeb yuav tsum raug coj mus rau hauv tus account kom raug xam. Cov tuam txhab lag luam thiab cov chaw muab kev pabcuam yuav tsum muaj kev sib txuas lus zoo kom paub meej txog kev tu vaj tse thiab cov txiaj ntsig xav tau, txhawm rau xaiv tus nqi tshaj plaws - cov tshuaj ntxuav tau zoo. Lub pob tshab thiab tsim nyog cov peev nyiaj tuaj yeem pab cov tuam txhab tswj xyuas cov nqi kho kom zoo dua qub thiab ua kom lub sijhawm ntev - ua haujlwm ruaj khov ntawm cov khoom siv hluav taws xob.
