The model utility content
Technical problem to be solved in the utility model provides a kind of volumetric efficiency height, the volume specific energy is low, reliability is high, noise is little Roots blower.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is as follows: comprise the cylinder of being made up of casing, front and back wallboard, be located at the gear tank on the wallboard, the impeller shaft of pair of parallel is housed in the casing, impeller is housed respectively on the impeller shaft, gas inlet end at described casing is provided with import buffering air cavity, between described import buffering air cavity and described impeller, be provided with the spirality import, gas outlet end at described casing is provided with outlet buffering air cavity, is provided with the spirality outlet between described outlet buffering air cavity and described impeller.
Adopt the Roots blower of technique scheme, owing to adopted the spirality import and export mix and inlet/outlet buffering air cavity, the guiding inlet gas enters aspirated volume continuously, pressurized gas gently are back to the low pressure air suction chamber, cut down the impact noise of air-flow significantly, when pulse pneumatic entered buffer cell, acoustic energy was released, and the total noise of centrifuge level reduces.
The gear tank oil hole is opened on the wallboard, prevent lubricant oil in the fuel tank by plug cock to external leakage.
The fore bearing grease lubrication of described blower fan, lubricating grease add hand-hole and are arranged on the front wallboard, have saved the drop tank in the conventional blower fan, and structure is simpler.
The impeller of installing on described impeller shaft is a triplicate blade impeller, and triplicate blade impeller improves the pulse frequency and the intensity of air-flow, and breathing action is more become gently, good seal performance, thus the volumetric efficiency of raising blower reduces the volume specific energy, reaches purpose of energy saving.
Gas inlet end at described casing is provided with the import silencing apparatus, is provided with the outlet silencing apparatus at the gas outlet end of described casing, adopts the inlet and outlet silencing apparatus to absorb the acoustic energy of sound wave fully, makes noise attentuation to minimum value.Periphery at described casing is provided with acoustic hood, and acoustic hood prevents propagation of noise in all directions, makes noise be lower than 75dB (A).
Described outlet silencing apparatus outlet end is connected with elastomeric joint, T connector, safety valve, pressure gauge and check valve.
The utility model disposes automatic control monitoring system: configuration temperature and pressure sensor, show fan bearing temperature, fuel tank temperature, delivery temperature, exhaust pressure, the easy-to-operat person understands the safe operation of blower fan at any time, implements blower mechanical property intellectual monitoring on the spot.
The utility model unit adopts pattern in groups, and wind collector, motor, import and export silencing apparatus, filter, elastomeric joint, safety valve, safety check, pressure meter are in one, and configurable monitor and control facility and acoustic hood.More compact structure, simple installation.Safety measure is perfect, the reliability height, and operation is more saved worry.
In sum, the utility model is a kind of compact structure, simple installation, beautiful shape; Energy consumption is little; Noise is low; Has the Roots blower of monitoring and guaranteeing the protective function of safe operation.
