At present, existing vehicular engine pressurized machine configuration need take into account high low-speed running, generally mates near high pulling torque point.Such as, and in some places, higher to fire protection requirement place, needs to be equipped with emergency bilge pump unit, need outfit to speedily carry out rescue work in emergency bilge pump unit and use motor.In emergency bilge pump unit, motor is fixed rotating speed running, pressurized machine need mate for rated point, reach optimum with the oil consumption making motor operate at rated point, power, discharge etc., therefore traditional vehicle supercharger can not meet the coupling requirement of motor in emergency bilge pump unit.
Model utility content
Technical problem to be solved in the utility model is: provide one to speedily carry out rescue work with engine supercharger, cannot mate motor in emergency bilge pump unit, cannot ensure the technical problem of engine performance to solve existing vehicle supercharger.
For solving the problems of the technologies described above, the technical solution of the utility model is: speedily carry out rescue work with engine supercharger, comprise turbine, gas compressor and intermediate, described gas compressor comprises compressor impeller, vane diffuser and compressor casing, described compressor impeller comprises wheel disc, described wheel disc is evenly equipped with several the first blades, the first radial flow path is formed between adjacent two described first blades, each described first blade includes air dam and portion of calming the anger, described air dam bends along the sense of rotation of described wheel disc, described in calm the anger the radial direction straight extension of portion along described wheel disc.
Improve as one, described vane diffuser comprises annular slab, a side of described annular slab is evenly equipped with several second blades, forms the second radial flow path between adjacent two described second blades.
As further improvement, described annular slab and the second blade are wholely set.
After have employed technique scheme, the beneficial effects of the utility model are: comprise wheel disc owing to speedily carrying out rescue work with the compressor impeller of engine supercharger, described wheel disc is evenly equipped with several the first blades, each described first blade includes air dam and portion of calming the anger, described air dam bends along the sense of rotation of described wheel disc, the described radial direction straight extension of portion along described wheel disc of calming the anger, thus improve the strength and stiffness of the first blade, pressurized machine can be matched with the motor in emergency bilge pump unit, thus ensure the oil consumption that motor operates at rated point, power, discharge etc. reaches optimum, this is speedily carried out rescue work and eliminates the bleed valve of vehicular engine with engine supercharger simultaneously, also makes structure simple, failure rate is low.What the utility model provided speedily carry out rescue work can match with the motor in emergency bilge pump unit with engine supercharger, thus ensures that oil consumption, power, discharge etc. that motor operates at rated point reach optimum; And structure is simple, failure rate is low.
A side due to the annular slab of described vane diffuser is evenly equipped with several second blades, forms the second radial flow path between adjacent two described second blades, thus can raise the efficiency.
Because described annular slab and the second blade are wholely set, facilitate and manufacture and install.
