Onwini no a wɔbɛhwɛ so no ne ade titiriw a ɛbɛma mfiri no ayɛ adwuma sɛnea ɛsɛ na ama ne nkwa nna ayɛ kɛse. Nea edidi so yi yɛ ahwɛyiye atitiriw bi a ɛsɛ sɛ woyɛ:
1. Da biara da nhwehwɛmu .
Appearance Inspection: Ansa na wobɛyɛ adwuma da biara anaa shift biara no, hwɛ sɛnea cooler no te, a sɛ ebia shell no wɔ leakage, titiriw tube sheet connection, inlet ne outlet flanges, welds ne afã afoforo.
Ɔhyew sohwɛ: Fa nnwinnade te sɛ infrared thermometers di dwuma fa susuw ɔhyew a ɛwɔ inlet ne outlet pipes a ɛwɔ cooler no mu no mu de hwɛ hu sɛ ɔhyew no wɔ nea ɛfata no mu.
Nhyɛso a wɔde hwɛ: Hwɛ nhyɛso kyerɛwtohɔ adwinnade no wɔ nsu a ɛkɔ mu ne nea efi mu ba no mu, kyerɛw nhyɛso bo no, na hwɛ sɛ nhyɛso no gyina anaa.
2. Nsiesiei a wɔyɛ no daa .
Adwuma a wɔde siesie: Hohoro cooler no abon no mu yiye, yi mfutuma, ngo ne efĩ afoforo a aboaboa ano wɔ soro, kwati sɛ ɛbɛka ɔhyew a ɛbɛsɛe no na asɛe abon no.
Cooling Medium Inspection and Replacement: Sɛ onwini no de nsu ne nneɛma afoforo a ɛma onwini a ɛnyɛ den sɛ ɛbɛgu fĩ anaasɛ wɔayɛ no kɛse di dwuma a, ɛho hia sɛ wɔsɔ ne nsu no su hwɛ daa, hwɛ pH bo, nneɛma a ɛyɛ den, nneɛma a wɔde asɛn hɔ ne nsɛnkyerɛnne afoforo, na wogyina sɔhwɛ no mu nsɛm so si gyinae sɛ ebia nsu a wɔde yɛ adwuma anaasɛ wɔde besi ananmu a egyina nea efi sɔhwɛ no mu aba so.
Bolt tightening: Hwɛ bolts wɔ connection point biara a cooler no, a connection bolts a ɛda tube sheet ne shell ntam, connection bolts a ɛwɔ inlet ne outlet flanges no mu, ne nea ɛkeka ho Fa torque wrench a ɛfata di dwuma de hyɛ mu den sɛnea torque ahwehwɛde ahorow a wɔakyerɛ no te na amma nhama no ansan amfi mu esiane vibration a efi VIBRation no mu bere a wɔde VIBRation no reyɛ adwuma a ɛbɛma nsu a ɛretu no aba, a ɛde nsu a ɛretu no bɛba, na ɛde ɔhaw ahorow aba.
3. Afe afe nsiesie .
Nhwehwɛmu ne ahotew: Sɛ woto mu wie a, bue cooler no awiei kataso no, twe tube bundle no, na yɛ nhwehwɛmu a ɛkɔ akyiri wɔ tube bundle no mu ne akyi nneɛma ne abon no mu fasu no ho. Hwɛ sɛ tube bundle no wɔ corrosion, wear, deformation, ne nea ɛkeka ho Sɛ wopɛ tube bundles a ɛwɔ ɔhaw ahorow a, wubetumi asi gyinae sɛ wobɛsiesie anaasɛ wobɛsesa sɛnea asɛe no te.
Instrument calibration: Calibrate temperature instrument, pressure instrument, ne nea ɛkeka ho a wɔasiesie no wɔ cooler no so na ama wɔn susudua no ayɛ pɛpɛɛpɛ.
Anti-nkitahodi ayaresa: Wɔyɛ anti-nkuruwankuruwa ayaresa wɔ akyi abon no so ne dade a wotumi hu no ani wɔ cooler no mu. Wɔ akyi abon no afã horow a ayɛ mmerɛw no ho no, ɛsɛ sɛ wodi kan yɛ nkannare fi hɔ (wɔbɛbɔ, anhwea a wɔde abɔ so, ne nea ɛkeka ho), na afei wɔde anti-corrosion paint a ɛfata adi dwuma; Wɔ dade a ɛwɔ mu no ani so no, wobetumi de anti-corrosion coating adi dwuma sɛnea tebea ankasa te de ama corrosion resistance a ɛwɔ nnwinnade no mu no ayɛ kɛse na atrɛw ne som nkwa mu.
4. Spare afã horow sohwɛ .
Fa spare parts inventory management system a edi mũ si hɔ de sie spare parts a wɔtaa de di dwuma te sɛ gaskets a wɔde hyɛ mu, tube bundles, bolts, ne nea ɛkeka ho daa kan spare parts dodow no ara de hwɛ hu sɛ spare parts no dɔɔso na ɛyɛ papa. Sɛ nnwinnade no di nkogu na ɛsɛ sɛ wɔsesa a, wobetumi de spare parts ama wɔ bere ano de atew bere a wɔde yɛ adwuma no so.
