Technical field
The present invention relates to a kind of roots blower, especially a kind of forced air-cooled complete intensive roots blower unit.
Background technique
Roots blower is a kind of typical displacement blower, and it relies on the change of rotor volumes, and the mechanical energy added by prime mover is pressure and the kinetic energy of gas.Compared with centrifugal blower, it has the advantages such as pressure ratio is high, flow is little by drag effects, air feed is stable, but ubiquity the shortcoming that efficiency is low, noise is high in the process used, its noise mainly comprises mechanical noise, the noise of vibration of foundation radiation, the electric moter noise of the air power noise of suction port and relief opening radiation, casing and bearing radiation.Because blower fan produces larger noise penalty working condition, pollute living environment, thus day by day cause people to the attention of fan noise.The common unit floor space of roots blower is large, and underintegration is high, and erection space is large, assembling, maintenance, repair inconvenience, and unit noise is high, cannot meet the requirement of user to noise.The propeller fan that acoustic hood is worn takes up room greatly in acoustic hood inside, and needs separately power supply, adds the cost of production of acoustic hood, safeguards that improper having an accident brings unnecessary loss to enterprise in addition.
Summary of the invention
Technical assignment of the present invention provides a kind of forced air-cooled complete intensive roots blower unit for above-mentioned deficiency of the prior art, this a kind of forced air-cooled complete intensive roots blower unit is had the ventilating fan on acoustic hood and is driven by the main shaft height rotating speed of roots blower, directly the heat in acoustic hood is discharged, both the inner space of acoustic hood had been increased, the heat accelerating acoustic hood inside is discharged, again reduce the processing cost of acoustic hood, save the feature of electric consumption.
The technical solution adopted for the present invention to solve the technical problems is: it comprises roots blower, complete machine frame, tensioning support, motor and acoustic hood, described roots blower, complete machine frame, tensioning support and motor are separately positioned in acoustic hood, roots blower and tensioning support are separately positioned in complete machine frame, the top of tensioning support is provided with motor, motor is connected with roots blower by drivign belt, the side of described acoustic hood is provided with air inlet duct, opposite side is provided with air vent, described air vent is positioned at outside the main shaft of roots blower, acoustic hood inside described air vent is provided with ventilating fan hole, ventilating fan is provided with ventilating fan in hole, described ventilating fan is connected with the main shaft external part of roots blower by coupling.
The air inlet of roots blower is provided with suction muffler, and outlet port is provided with exit silencer, and described exit silencer is positioned in complete machine frame, integrally formed with complete machine frame.
The end of exit silencer is provided with exhaust duct, is connected between exhaust duct with exit silencer by elastomeric joint, exhaust duct is provided with Decompression valves and pressure gauge, Decompression valves is also provided with one-way valve, Decompression valves end and anti-Flange joint.
Beam is provided with between described complete machine frame and ground.
Described complete machine frame is fixed on ground by steel EXPANSION ANCHOR BOLTS.
Compared to the prior art the forced air-cooled complete intensive roots blower unit of one of the present invention, has following outstanding beneficial effect: integration degree is high, and install, Maintenance and Repair are convenient, floor space is little, and environmental protection, defening effect are good; Ventilating fan on acoustic hood is driven by the main shaft height rotating speed of roots blower, directly the heat in acoustic hood is discharged, both the inner space of acoustic hood had been increased, the heat accelerating acoustic hood inside is discharged, again reduce the processing cost of acoustic hood, saved electric consumption, exit silencer adopts anti-formula structure, be made of one with complete machine frame, there is the high and low noise of bulk strength, efficiency is high; Suction muffler is arranged on roots blower intake grill position, can quick-replaceable, can effectively reduce the features such as the air power noise of suction port radiation.
