Air flow and pressure can be customized2. Stable air flow and less pressure variation3. Clean air not with oil moist4. Construction simple and easy maintenance5. Bearing are all lubricated by oil moist6. Long service lifeDescription of Performance parametersThe performance parameters table shows the model, outlet diameter, rotate speed, discharge pressure, air capacity and power of motor.1. The air capacity and pressure in the tables is in standard suction state. The standard suction state is 20ºC temperature, 1.033 kgf/cm2(101.3Kpa) Standard atmospheric pressure and 65% relative humidity.2. The air capacity and pressure range of some blower models is repeated, to ensure the service life and low noise, should use the larger model.Type of technologyPositive displacement blowersDesignPositive pressureAir capacity266 to 376 m³/minDischarge Pressure9.8 to 49.0KpaMediumAir, Neutral gasesConveyingOil-freeWeight9195kgDischarge Diameter600mm(or customized)Blower Structure DiagramNo.NameMaterialQ' tyNo.NameMaterialQ' ty1ShellHT200114Z sealing ringNitrile rubber12ImpellerHT200215Gear35CrM23Drive shaft45Cr116Gear lock washerQ23524Driven shaft45Cr117Gear locknutSS40025Drive side sidingHT200118GearboxHT20016Gearside sidingHT200119Sleeve4517Drive bearingNSK220End coverQ23528Driven bearingNSK221Pin4519Sealing ringNitrile rubber222Plug35110Sealing ringNitrile rubber223Oil gauge111Bearing sleeve45424Vent112Bearing coverHT200125Grease nippleC3605213Bearing coverHT200126Gearbox sealsBarley paper2Blower AccessorieInlet filter silencer, Discharge silencer, Anchor bolts, baseframe, Safety valve, Check valve, Discharge pressure gauge, Flexible connections, Lubricant oil.Roots Blower ApplicationWater TreatmentAquaculturePowder and granulestransportationBe used in water treatment plant for water purification and sediment mixingBe used in avariety of fish pond foroxygen supply and mixing, and also for aquariums and live fish tankPowder or granules(such as plastic materials, etc.) can be transported by pressure or vacuumIncineratorBallast pumpSandblastAir combustion and exhaust emissionsUsed for chemical liquid unloading and other ballast pumpsUsed as air source for blast jetBoosterCompost fermentationCereals TransportationUsed for high-pressure exhaust to make the gas into tiny moleculesHigh-pressure air takeinto the livestock manure tank to increase contact areaof livestock manure and air ,also apply to sewage treatmentCereals such as wheat aretransportedfrom the rotary pilot valve with airPipe clearingSaunaPlating BathUsed to remove dirt and iron dust during pipeline replacement or overhaulUsed for the sauna to provide air bubbles, mainly used for hospitals, hotels and etc.Use air to stir the electrolyte to keep the electrolyte circulation, and disperse the attached blister to make plating quickly, spread evenlyProduce line dryingCar wash drySmoke exhaustQuickly remove the water or oil on the cleaned itemsDry the car after washingExhaust smoke quickly to reduce pollutionStripping from moldAir cushion ofCut off machineDry air knifeEasy to remove the finished product after stampingIncrease buoyancy, easy to moveUse the blower to blow off the tiny dust and water droplets on the circuit boardFeed paper/clothWashing machineblow dryGas /heavy fuel injectionCollect plastic, cloth, paper and other scrap generated after trimmingDried bottles after washing, suitable for food industryProvide high pressure (2000 mmAq) and sufficient air volumeCommon malfunctions and SolutionMalfunctionsReasonSolutionBlowerCan not rotateCan rotated by handThe motor is damagedRepair or replace the motorCan rotatedround by handThe lobes are lockedOpen to repairThe impurity in blowerOpen tocleanCan rotateAbnormalsound orvibrationSkid, v-belt is too tight ortoo looseAdjust v-belt tensionPulley offsetReset pulleyPulley and belt coverfrictionAdjust belt coverBearing oil lack or agingTo replace the oilGearoil lack or agingTo replace the oilThe safe valve leakageAdjust the safe valveFoundation insufficientstrengthTo strengthen thefoundation strengthPiping resonanceEliminatebythe silencer and supportExhaust pressure risesabruptlySee *annotatedAnchor bolt is too looseTightenRotor interferenceOpen to repairThe impurity in blowerOpen tocleanCheck valve badReplaceOverheatingExhaust pressure risesabruptlySee *annotatedTemperature of working environment exceeds 40 ºCVentilated working environmentInlet silencer obstructionCleaning/replace filterAirflowinsufficientPipeline leaksTighten the pipe connectionInlet silencer obstructionCleaning/replace filterThe safe valve leakageAdjust the safe valveV-belt is too looseAdjust v-belt tensionExhaust pressure risesabruptlySee *annotatedExhaust pressure risesabruptlyShut off the valveFully open the valveThe water level risesAdjust waterlevelInlet/outlet pipe jamsCleaning debrisValve bad or twist reverseddirectionReplace or reverse directiontwistAirflow overpoweredReduce round speed or exhaustOil leakLubrication oil overmuchRefuel to the center of oil standardProcessing WorkshopFAQ1.
