Ɛbɛyɛ dɛn na mahu sɛ me heating element no nye .
Akwan pii wɔ hɔ a wobɛfa so ahu sɛ ebia ɔhyew afiri no asɛe anaa:
Hwɛ sɛnea ɔhyew afiri no yɛ adwuma: sɛ ɔhyew afiri no ntumi nyɛ hyew sɛnea ɛsɛ, anaasɛ ɛda adi sɛ ɔhyew no nyɛ papa sɛnea na ɛte kan no a, ebia biribi a enye wɔ ɔhyew tube. no mu a wubetumi abɔ mmɔden sɛ wobɛsesa ɔhyew ne nhyɛso. sɛ nkɛntɛnso no nyɛ kɛse a, ebia ɔhyew afiri no asɛe.
1. Fa multimeter susuw:
Susuw resistance: Fa resistance range ketewa a ɛwɔ multimeter no mu no susuw resistance value a ɛwɔ terminal ends of the heating tube. normal resistance value a ɛwɔ heating tube no mu no ɛsɛ sɛ ɛyɛ ohms. ɔhaha pii ase sɛ resistance value no yɛ kɛse dodo anaasɛ ɛkyerɛ sɛ infinite tube no betumi ahyew anaasɛ insulation no abubu.
2.Measure insulation adwumayɛ:
Fa multimeter no resistance range a ɛkorɔn no susuw resistance bo a ɛda terminal end ne outer shell a ɛwɔ heating tube. no mu no, ɛsɛ sɛ resistance bo a ɛyɛ daa no yɛ nea enni ano. sɛ resistance no yɛ kilo-ohms du du pɛ a, ɛkyerɛ sɛ insulation no abubu na asiane bi wɔ hɔ a ɛbɛma leakage.
3. Hwɛ ammeter akenkan no:
Sɛ ɔhyew afiri no sɛe a, thermostat no bɛkyerɛ sɛ ɛwɔ ahoɔden ma ɔhyew, nanso ammeter pointer no renhinhim anaasɛ akenkan no yɛ zero, a ɛkyerɛ sɛ ɔhyew tube no ntumi nnya ahoɔden.
4. Hwɛ ɔhyew a ɛba no so:
Sɛ ɔhyew a ɛwɔ ɔhyew afiri no mu no ntumi nkɔ bo a wɔahyɛ no so, anaasɛ ɔhyew no nyɛ pɛpɛɛpɛ, asase no ani yɛ kusuu anaasɛ nsu a ɛwɔ mu no nyɛ papa a, ɔhyew afiri no nso betumi asɛe.
Ɛsɛ sɛ yɛhyɛ nsɛm a edidi so yi nsow bere a wɔresɔ ɔhyew afiri no su ahwɛ no:
Power Off and Cooling: Ansa na wobɛsusu no, hwɛ sɛ wɔadum ɔhyew afiri no na ayɛ nwini akodu baabi. eyi betumi akwati asiane a ɛne sɛ anyinam ahoɔden bɛbɔ ne susuw mfomso.
1. Fa nnwinnade a ɛfata di dwuma:
Fa mfiri a wɔde sɔ hwɛ te sɛ thermocouple thermometers, infrared thermometers, multimeters anaasɛ resistance susudua di dwuma{0}} saa nnwinnade yi betumi aboa wo ma woasusuw ɔhyew ne ahoɔden a ɛwɔ ɔhyew tube no mu pɛpɛɛpɛ.
2. preheating ne calibration: .
Ansa na wode thermometer no bedi dwuma no, ma no nyɛ hyew ma 5-10 simma na ama woadu baabi a ɛhɔ yɛ hyew. bere koro no ara mu no, wɔkamfo kyerɛ sɛ di kan sɔ ɔhyew afiri a ɛyɛ daa no nhwɛ na ama woate ne soro hyew ne mprempren bo a ɛkɔ soro no ase ansa na woasiesie ɔhaw ahorow.
3. Nhwehwɛmu:
Hwɛ sɛnea ɔhyew afiri no pue wɔ w’ani so hwɛ sɛ ebia asɛe pefee te sɛ mpaapaemu, abubu anaasɛ nsɛe. eyinom betumi ayɛ sɛnkyerɛnne a ɛkyerɛ sɛ ɔhyew afiri no asɛe.
4. Ɔsɔretia susudua:
Fa multimeter anaa resistance susuw adwinnade di dwuma de kyekyere sɔhwɛ clamps no wɔ ɔhyew tube no ano abien no nyinaa, kyerɛw resistance bo no na fa toto rated value. ho sɛ resistance bo no yɛ soronko kɛse wɔ rated value no ho a, ebetumi akyerɛ sɛ ɔhyew tube no yɛ mfomso.
5. insulation susudua:
Fa insulation resistance measuring instrument di dwuma fa hwɛ insulation adwumayɛ a ɛwɔ ɔhyew tube. no mu Fa awiei biako bata ɔhyew tube no akyi abon no ho na awiei foforo no kɔ cable anaa terminal. no so sɛ insulation resistance bo no sua a, ebetumi akyerɛ sɛ insulation adwumayɛ no asɛe.
6. Ɔhyew a wɔde susuw nneɛma:
Fa thermometer anaa infrared thermometer susuw ɔhyew afiri no ani hyew na fa toto ɔhyew a ɛyɛ adwuma daa. ho sɛ ɔhyew no nyɛ nea ɛfata a, ebetumi akyerɛ sɛ ɔhyew afiri no yɛ mfomso.
7. Bɔ sɔhwɛ mfiri ho ban:
Sɛ woresusuw current a, hwɛ yiye wɔ sɔhwɛ kramp no ho banbɔ mu na amma circuit tiawa; Sɛ woresusuw ɔhyew a, hwɛ sɛnea wobɛbɔ ɔhyew kyerɛwtohɔ no ho ban na akwati sɛe.
