Screw BlowerOil FreeLow NoiseAir 100%Labyrinth seal andspiral seal assembliesThere is no internal compression of roots blower, which results in the reverse filling of higher pressure air in the pipenetwork into the compression chamber during exhaust, forming air impact, producing high low-frequency air noiseand great vibration of equipment. The screw blower has internal compression, and its compression chamber exhaustpressure is close to the pipe network pressure, smooth exhaust, greatly reducing the vibration and noise of theequipment. The noise of the screw blower is concentrated in the high-frequency part, and this part of the noise canbe dealt with by silencer and noise reduction measures. Thus, the noise of the whole screw blower is 30dB (A)lower than that of the Roots blower.After analyzing the frequency spectrum of the sound source, the professional design of customized intakeand exhaust silencers greatly reduces the noise transmission of oil-free screw compressors to the externalenvironment. The whole oil-free screw blower is completely sealed with an acoustic enclosure. The airinlet is processed by a specially designed noise-reducing air inlet and then enters the internalchambers. The transmission of noise from internal to external is minimized.Precision designed labyrinth seal and spiral seal assemblies provide users with true oil-freelow-pressure air. Sealed components are frictionless, more reliable, and minimize powerconsumption.Inside the exhaust silencer, there is no asbestos, PE cotton and other sound-absorbing materials.The sound elimination is achieved through acoustic design, therefore there is no secondarypollution to the air, so as to ensure the requirement for clean air.IntelligentControlReal-time control PLC intelligent control, 6"colour LCD touch screen display. English graphic interface, easy to operate, user friendly. The controller can realize the start-stop control of theequipment, frequency conversion control (Variablefrequency version), real-time monitoring the exhaustpressure, exhaust temperature, lubricant oil pressureand temperature, the maintenance time, error earlywarning and error record, etc. Support RS485 connection, support joint control andremote control. Variable frequency version supportsthe signal control of the concentration of DissolvedOxygen (DO). Standard wireless internet module allows remoteaccess from PC, Pad, smartphone, to be able to checkthe equipment running status at any time from anywhere.LowNoise
Screw BlowerHigh EfficiencyUCBS oil-free screw blower is skid-mounted integrated box type. Blower air end, motor, transmission, intake filter, intakeand exhaust silencer, shock absorber, safety valve, exhaust check valve, starting cabinet, control system, frequency converterand sound insulation cover are all integrated and installed on the base. All units before factory leaving are to be filled withlubricating oil and machine tested. There is no need to embed an expansion bolt foundation for installation. Only a smoothand firm cement floor is required for installation. Connect the exhaust pipe network, connect the power cable, the machinecan be started and utilised.Compared with the traditional Roots blower, UCBS oil-free screw blower has higher efficiency from the technical principle.See below P-V performance chart of Roots blower and screw blower for details.It is recommended to install a butterfly valve on the exhaust pipe of each blower to facilitate cutting off the connection withthe pipe network for equipment maintenance. The connection between the branch pipe and main pipe should not use "T"type tee, but it is recommended to use "Y" type tee, which can reduce the loss of wind pressure.An outdoor rain protection kit option allows you to install your blower equipment close to a point of use, such as next to asump.4 1 Inspiratory process. As the Roots' rotor rotates, air is drawn in untilthe intake is closed.1 2 External compression process. It can be broken down into twoprocesses. The Roots rotor continues to rotate, the volume of the enclosedspace does not change, there is no internal compression; Until theenclosed space is suddenly exposed to the vent, the pressure from thepiping network increases the air pressure to this space.Energy Consumption2 3 Exhaust process. As roots rotor continues to rotate, the air thathas been boosted will be released to the piping network.P-V performance chart of Roots blowerUCBS oil-free screw blower can save up toenergy compared to Roots blowerEnergySavingEnergyConsumption4 1 Inspiratory process. As the screw rotor rotates, the volume of thespiral groove increases gradually, and the air is drawn into the blower untilthe intake is closed.1 2 Internal compression process. The intake port has been closed, andthe exhaust port has not been opened yet. Due to the spiral design, thespiral movement makes the volume of the closed spiral groove smallerand smaller, resulting in internal compression and pressure rise.2 3 Exhaust process. As the rotor continues to rotate, the exhaust portopens and the compressed air is discharged from the blower.P-V performance chart of screw blowerUnder the same condition of air volume and pressure, screw blower needs much less power consumption. In the figure, the green part is theenergy savings. Compared with the traditional Roots blower, the screw blower can save up to 35% energy. The higher the pressure, the moresignificant the energy-saving effect, with an average energy saving of 20%. With precision design and manufacture, intelligent control andfrequency conversion drive, compared with Roots blower, the energy efficiency of oil-free screw blower can reach 20%-50%.Plug-and-Play
