automotive air conditioner blower, by definition, in the automotive air conditioning system is mounted conveying means for a cleaning gas such as air, is an important ldquo automotive air conditioning system; rdquo ;, to help air circulation inside the car of great significance.
an action principle blower
The blower basically consisting of six parts: a motor, an air filter, blower body, the air chamber, the base (and tank), drip nozzle. Into the cylinder by the blower rotor eccentricity bias operation, and the change in volume between the air vane rotor slot suction, compression, discharge. Blower pressure difference in operation to the automatic drip nozzle lubrication to reduce friction and noise, while maintaining the gas within the cylinder not backflow added dropwise cylinder, also known as vane type fan blower.
In conveying medium blower clean air, clean gas, mainly sulfur dioxide and other inert gases. It may also be produced on demand delivery of other flammable, explosive, erodible, and special toxic gases. Thus it can be widely used in the metallurgical, chemical, fertilizer, petrochemical, food, building materials, petroleum, mining, textile, gas station, pneumatic conveying, sewage treatmentAnd other industrial sectors.
Structure 2
impeller: selection involute surface, high volume utilization.
Synchronization gears: the gear ring and the hub composition, to facilitate adjustment of impeller clearance.
base: in common base equipped with a small fan, with the fans only large fan base, to facilitate installation.
of the body: the housing and the left and right wall composition. Left and right wall and the bearing housing, the sealing portion is mounted in the other of the left and right panels can be interoperable.
bearing: near the coupling end selected as the positioning end 3000 double row spherical radial roller bearings. Near the free end side as a gear selection 32000 type single roller bearing to accommodate radial short cylindrical axial displacement of the rotor heat distention.
Lubrication: gears are submerged bearing splash lubrication. Lubricating effect, safe and reliable.
Transmission: Direct coupling to the main. If the required performance specifications, transmission V-belt pulley can also be used in the embodiment. Couplings for couplings, shock can be alleviated and the compensation amount of axis deviation. Large flow fan divided by motor as a drive machine, the steam turbine may be used, or other drive machine.
3. The blower characteristics
1, the blower rotor, after all static and dynamic balance check. Finished smooth operation, minimal vibration.
2, a higher blower speed, the gap between the rotor and the rotor, the rotor and the body is small, so that small leakage of high volumetric efficiency.
3, since the operation of the impeller in the body without friction, does not require lubrication, the oil-gas discharge. Is an ideal industrial strength chemicals, food and other air transport.
4, the operation of the blower fan volume belongs. When used, along with changes in pressure, flow change is very small. But as the speed and flow rate changes. Therefore, the choice of a wide range of pressure, flow rate may be selected by selecting the rotational speed to achieve the desired.
5, the structure of the blower determines the mechanical friction loss is very small. Because only the sub-bearing and gear selection with a mechanical contact with the rotor, the housing and the ring gear have a sufficient mechanical strength. Operational safety, long service life is a major feature of blower products.
