Structural characteristics and design principles
The cooling fan YB2-132M-4 adopts an axial flow structure design. The fan blades are based on aerodynamic optimization. Through the precise matching of the blade curvature and the inclination angle, high air volume output is achieved at low speed. The fan frame and fan blades are usually made of lightweight aluminum alloy or engineering plastics, taking into account both strength and temperature resistance. The bearing system uses maintenance-free ball bearings or oil-containing sliding bearings to ensure the stability of long-term operation. According to the specifications of the matching motor YB2-132M-4, its design speed range is usually controlled in the range of 3000-4500rpm, balancing the heat dissipation efficiency and noise control requirements, and adapting to the synchronous speed characteristics of the 4-pole motor (1500rpm).
Technical performance advantages
1. Efficient heat dissipation and temperature control capabilities
Through directional airflow guidance technology, cooling air can penetrate the gap between motor windings and the air gap between stators and rotors, significantly improving heat exchange efficiency. Actual measured data shows that under ambient temperature of 40°C, the fan can reduce the temperature rise of motor windings by 15-20K, effectively delaying the aging of insulation materials.
2. Low noise and vibration suppression
The asymmetric fan blade layout and edge chamfering process are used to reduce the broadband noise generated by air turbulence. Combined with the dynamic balancing calibration process, the rotor eccentricity is controlled within 0.05mm, making the operating noise ≤65dB(A) (measured 1 meter away from the fan), meeting the strict requirements of IP55 protection level for internal cleanliness.
3. Enhanced environmental adaptability
In response to explosion-proof scene requirements (such as YB2 series motor matching scenes), the fan assembly is treated with electrostatic discharge and flame-retardant materials, meeting the Ex dⅡBT4 explosion-proof certification standards. At the same time, the surface of the fan blade can be treated with an anti-corrosion coating, which is suitable for industrial environments with high humidity and oil mist.
Typical application scenarios
This cooling fan YB2-132M-4 is widely used in the following fields:
- Power equipment system: supporting the drive motor of high-pressure hydraulic equipment such as steam turbine EH oil pumps and circulating pumps to ensure that the oil temperature is stable in the design range of 45-55℃.
- Petrochemical explosion-proof scenario: YB2 series explosion-proof motors used to drive compressors and centrifugal pumps to achieve safe heat dissipation in flammable and explosive environments.
- Heavy-duty industrial equipment: adapt to large inertia load motors such as machine tool spindles and mining crushers to prevent insulation breakdown caused by continuous overload.
Selection and maintenance points
When selecting, focus on motor power, installation space and air duct matching. Taking the YB2-132M-4 motor as an example, the shaft extension size must be precisely matched with the fan flange interface to avoid resonance caused by assembly tolerances. During daily maintenance, dust on the fan blades should be removed regularly and the lubrication status of the bearings should be checked. It is recommended to add high-temperature resistant grease every 2000 hours of operation and install a dustproof mesh cover in a high-dust environment.
