2.2Working Principle
Becauseofresistance,alloyresistancewireinsidetheheatingpipe willheatafter
energization.Heating isachieved bytightlycompressed magnesiumoxide powder
filled inthe heating pipeconductsheat totheheating pipebody.
2.3Inspection
Accordingtothefollowingprinciple, youcanuseamultimetertotesttheresistanceof
heating pipe when you check whetherthe heatingpipe isdamaged,if the tested value
isinfiniteormuchlargerthan the actualresistance,heating wireinthe middleof
heating pipe hasbeen disconnected,unabletoachieveheating,needstobe
replaced.
You can getthe actualresistanceofheatingpipeaccording toitspower,the
calculation method is:
R=U2/P
RResistance, unitis Ω.
UVoltage of heating pipe, unitisV.
PPowerof heatingpipe, unitisW.
Forexample,the voltage ofaheating pipeis380V,and the powerofheating pipe is
12kw,wecan get the actualresistanceis:
380v*380v/12000w≈12Ω
2.4Replacing
Heatingpipe mustbe replaced withthe samespecifications,adaptablevoltageand
powerinordertoachievethe originalheating effect.If not, itwillcauseheating pipe

4.3Working Principle
Workingprincipleof thermocouples:
Twodifferentconductors(named thermocouplewireand hotelectrode)are
connected tothe circuit, when the temperatureisnotsameatengagementpoint, an
electromotiveforceisgenerated inthe circuit,whichiscalledthermoelectriceffects,
and the electromotiveforceiscalled thermoelectricforce.Thermocouplemeasure
temperaturethrough the principle,among them,directused tomeasuremedium
temperatureend iscalled working end(alsocalled measuring end),the otherend is
calledcoldend(alsocalled compensating end);coldend connectswithmonitorand
associated instruments.
Workingprincipleof microcomputerboard:
The temperaturesignalwhicharemeasured bythermocoupletransformsintoanalog
signal, transferstoamicrocomputerchipthrough input circuit,afterthe process,intoa
digitalsignal,the executivemoduleiscontrolled bythe outputcircuittoobtain
accuratetemperaturecontrolperformance.

Becausethe lattersimplyexclude alarm, but the actualdirection of rotation of

5.3Working Principle
Indehumidification process,honeycomb-rotorisdividedintodehumidifyingzone,
regeneration zone and coolingzone,inordertoensurethatworkisacontinuous
dehumidification process.When the wetairtobe treated intothe dehumidifyingzone
ofrotor,watermoleculesintheairareabsorbed bythe hygroscopicmaterialinside
the rotor,anddehumidifyingzoneofrotorissaturatedbecauseofabsorbingsome

Regularlycheck the honeycomb-rotormotors,sensors, speed adjuster, adjuster

inproperworkingcondition.
Regularlycheck and replacethe seals.

5.4.2Honeycomb-rotorCleaning Method
Cleaningmethodsand stepsareasfollows:
Whennot usingregeneration dry, blowing airhumidityexceeds60%RH tomake
the rotormoisturesaturation. If the airhumiditybelowstandard, youcan close
regeneration electricheating, keep dryblowerand drivemotorcontinuous
operation, tomakerotormoisturesaturation effect. If theairistoo dry, tryusing
humidistat toincreasehumidity, thestep requires1hour.

5.5Honeycomb-rotorDeteriorationPhenomenon
Becauseofrepeated adsorption and regenerationofadsorbentmolecularsieveand
silicone,the phenomenon whichadsorption capacityoftheadsorbentgraduallydrop
iscalled adsorbent deterioration phenomenon.
Adsorbentdeteriorationphenomenon ismainlycaused byhysteresisandadsorbent
regeneration.
