According to above-mentioned structure, the air blast of the present embodiment has following characteristics：

The present embodiment is applied to (include magnetic suspension, gas on the suspension air blast using high-speed electric expreess locomotive driving as shown in Figure 3 Suspend).Air blast be placed in cabinet, cabinet be air blast filtration, air-breathing, exhaust, cooling assembly：Including air blast, in Effect filter, air suction silencer, high efficiency particulate air filter, motor cooled exhaust pipe, dividing plate.High speed suspension air blast is by air blast machine Shell, machine shaft, impeller, spiral case, blower discharge pipe, induction chamber, motor cooling fan etc. form.Rough filter, height Effect filter was the device of air filtering；High efficiency particulate air filter is more abundant to the filter capacity of air.Air blast cabinet is by dividing plate It is divided into two parts.The gas channel of connection left and right two cabinets is had on dividing plate.In scheme, left side cabinet is separated by high efficiency particulate air filter For upper and lower two parts.The bottom of left side cabinet is connected by gas channel with right side cabinet.Operationally, motor drives air blast Main shaft, main shaft impeller are rotated, and due to the rotation work done of impeller, so that the suction side of impeller is occurred low on the right side of dividing plate Pressure, and then realize continuous air-breathing and the exhaust of impeller.The effect by screen pack for the extraneous air of cabinet, is carried out to sucking air Filter, so that impurity in gas is reduced and meet the requirement to air quality for the suspension blower discharge.Air after being filtered is successively Through the induction chamber of air blast, impeller eye, impeller blade, impeller outlet, spiral case, finally enter blower discharge pipe.Suspend Air blast main shaft, impeller connected mode are axis nut check.When air blast runs, drive motor while motor shaft rotates Axle left distal end cooling fan operating, cooling fan be aerofoil fan, the operating of this fan can be by blower casing Gas pumps on the left of air blast from right side by electric machine rotor gap, finally discharges from cooling wind blast pipe；In this process Due to low pressure occurring at housing cooling air inlet on the left of middle cabinet, start air-breathing from cabinet around.Motor shaft and cooling wind The connected mode of fan is bonded.Due to the operating of cooling wheel, cause in the cabinet of left side and produce low pressure, therefore by medium air filtration A part of outside air after device filters can enter into cabinet left bottom, Ran Houzai from the right side of cabinet through gas channel Enter the cooling completing motor inside blower motor through filtering further of high efficiency particulate air filter from housing.Blower motor is fixed The through hole of the uniform distribution of circumferencial direction is disposed with subshell body, the position of this through hole is attached positioned at magnetic suspension journal bearing sensor Closely so that the cooling air entering from through hole effectively can directly admit air into motor from motor one end together by cooling sensor Stator is central with the gap of rotor and then rotor is also cooled down.High efficiency particulate air filter is the assembly of integrated efficient filter, permissible Directly directly extract out, insert along cabinet horizontal direction, install simple with replacement operation.High efficiency particulate air filter ran in air blast Only the air through medium effeciency filter is filtered in journey, can fully improve the producing level of this high efficiency particulate air filter.

The air blast of the present embodiment also has some alternate embodiments, specific as follows：

1st, the air blast described in the present embodiment is horizontal type structure, and the vertical blower fan structure meeting function above falls within The protection category of this programme；

2nd, high efficiency particulate air filter overall structure or other Split type structures that function can be met；

3rd, the structure of the gas channel on central dividing plate does not limit, and meets the structure of airflow；

4th, the structure arrangement of high efficiency particulate air filter does not limit, and the not necessarily lower section on the left of cabinet meets the arrangement of function.

The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for this For the technical staff in field, the utility model can have various modifications and variations.All of the present utility model spirit and principle Within, any modification, equivalent substitution and improvement made etc., should be included within protection domain of the present utility model.
