Questions and Answers about Frequently Asked Questions about Diesel Generator Sets

Ā 

  1. WhatĀ areĀ theĀ conditionsĀ forĀ theĀ parallelĀ operationĀ ofĀ twoĀ generatorĀ sets?Ā WhatĀ devicesĀ areĀ usedĀ toĀ completeĀ theĀ parallelĀ work?

Ā 

Answer:Ā TheĀ conditionĀ forĀ usingĀ parallelĀ machinesĀ isĀ thatĀ theĀ instantaneousĀ voltage,Ā frequencyĀ andĀ phaseĀ ofĀ theĀ twoĀ machinesĀ areĀ theĀ same.Ā TheĀ generatorĀ setĀ isĀ commonlyĀ knownĀ asĀ "threeĀ simultaneous".Ā UseĀ aĀ specialĀ parallelĀ machineĀ deviceĀ toĀ completeĀ theĀ parallelĀ machineĀ work.Ā ItĀ isĀ generallyĀ recommendedĀ toĀ useĀ fullyĀ automaticĀ parallelĀ cabinets.Ā TryĀ notĀ toĀ manuallyĀ Paralleling.Ā TheĀ successĀ orĀ failureĀ ofĀ manualĀ parallelingĀ dependsĀ onĀ humanĀ experience.Ā TheĀ authorĀ boldlyĀ assertsĀ withĀ moreĀ thanĀ 20Ā yearsĀ ofĀ experienceĀ inĀ electricĀ powerĀ workĀ thatĀ theĀ reliableĀ successĀ rateĀ ofĀ manualĀ parallelingĀ ofĀ dieselĀ generatorsĀ isĀ 0.Ā TheĀ conceptĀ ofĀ manualĀ parallelingĀ isĀ appliedĀ toĀ theĀ smallĀ powerĀ supplyĀ system,Ā becauseĀ theĀ protectionĀ levelsĀ ofĀ theĀ twoĀ areĀ completelyĀ different.

  1. WhatĀ areĀ theĀ reasonsĀ forĀ theĀ highĀ waterĀ temperatureĀ alarmĀ toĀ shutĀ downĀ andĀ makeĀ itĀ unusable?

Ā 

Answer:Ā TheĀ waterĀ tankĀ isĀ leakingĀ orĀ theĀ waterĀ isĀ insufficient;Ā theĀ waterĀ temperatureĀ sensorĀ isĀ damaged;Ā theĀ waterĀ channelĀ ofĀ theĀ waterĀ tankĀ isĀ tooĀ dirtyĀ orĀ theĀ heatĀ sinkĀ isĀ tooĀ dirty.

Ā 

TheĀ fanĀ beltĀ isĀ wornĀ tooĀ muchĀ andĀ theĀ pressureĀ isĀ insufficient;Ā theĀ waterĀ pumpĀ isĀ wornĀ andĀ theĀ pumpĀ waterĀ isĀ insufficient;Ā theĀ openingĀ angleĀ ofĀ theĀ thermostatĀ isĀ notĀ enoughĀ andĀ thereĀ isĀ aĀ phenomenonĀ ofĀ jamming;Ā theĀ cylinderĀ gasketĀ isĀ damagedĀ andĀ theĀ waterĀ channelĀ isĀ connectedĀ toĀ theĀ cylinder;Ā Requirements;Ā engineĀ overloadĀ operation;Ā (includingĀ engineĀ fatigue)Ā excessiveĀ fuelĀ supply.

Ā 

  1. WhyĀ mustĀ theĀ workingĀ compartmentĀ ofĀ theĀ generatorĀ (electricĀ ball)Ā beĀ keptĀ clean?

Ā 

Answer:Ā IfĀ theĀ dieselĀ engineĀ sucksĀ inĀ dirtyĀ air,Ā theĀ powerĀ willĀ drop;Ā ifĀ theĀ generatorĀ sucksĀ inĀ sand,Ā dustĀ andĀ otherĀ impurities,Ā itĀ willĀ damageĀ theĀ insulationĀ betweenĀ theĀ statorĀ andĀ rotorĀ gap,Ā andĀ theĀ severeĀ oneĀ willĀ causeĀ burning.

  1. WhichĀ levelĀ ofĀ energyĀ doesĀ electricĀ energyĀ belongĀ to?Ā WhatĀ areĀ theĀ characteristicsĀ ofĀ alternatingĀ current?

Ā 

Answer:Ā ElectricĀ energyĀ isĀ aĀ secondaryĀ energyĀ source.Ā ACĀ isĀ convertedĀ fromĀ mechanicalĀ energy,Ā andĀ DCĀ isĀ convertedĀ fromĀ chemicalĀ energy.Ā TheĀ characteristicĀ ofĀ alternatingĀ currentĀ isĀ thatĀ itĀ cannotĀ beĀ storedĀ andĀ isĀ nowĀ used.

Ā 

  1. WhyĀ isĀ thereĀ waterĀ inĀ theĀ fuelĀ tankĀ andĀ howĀ toĀ preventĀ it?

Ā 

Answer:Ā QualifiedĀ fuelĀ willĀ notĀ containĀ impuritiesĀ andĀ waterĀ whenĀ itĀ leavesĀ theĀ factory,Ā butĀ itĀ willĀ beĀ moreĀ orĀ lessĀ mixedĀ withĀ dust,Ā dirtĀ andĀ waterĀ duringĀ transportationĀ andĀ storage;Ā Fuel.Ā TheĀ useĀ andĀ storageĀ ofĀ fuelĀ shouldĀ payĀ attentionĀ toĀ theĀ followingĀ points:Ā 1)Ā TheĀ fuelĀ shouldĀ beĀ storedĀ inĀ theĀ fuelĀ tankĀ forĀ moreĀ thanĀ 24Ā hours,Ā soĀ thatĀ theĀ waterĀ andĀ impuritiesĀ canĀ beĀ precipitatedĀ beforeĀ use;Ā 2)Ā TryĀ toĀ fillĀ upĀ theĀ dailyĀ fuelĀ tankĀ afterĀ eachĀ workĀ ,Ā soĀ asĀ toĀ preventĀ theĀ moistureĀ inĀ theĀ airĀ ofĀ theĀ fuelĀ tankĀ fromĀ mixingĀ intoĀ theĀ fuel;Ā 3)Ā WhenĀ fillingĀ theĀ fuel,Ā firstĀ wipeĀ theĀ funnelĀ andĀ theĀ endĀ capĀ ofĀ theĀ fuelĀ tankĀ clean.Ā TheĀ drainĀ cockĀ removesĀ accumulatedĀ waterĀ andĀ sediment
