The explosion-proof high-pressure fan is precision-cast in aluminum alloy, significantly reducing its weight. It features fully automatic processing equipment, standard production processes, and boasts advantages such as environmental protection, high efficiency, energy-saving, high pressure, large air volume, low noise, compact size, and lightweight.

Wide range of applications, suitable for various high explosion-proof requirements.

2. Fiberglass materials offer excellent corrosion resistance, high strength, reinforced safety structures, and minimal vibration. A computerized stress-strain analysis of the entire unit is conducted to enhance structural strength. This significantly reduces the risk of downtime caused by vibration, bringing you a safer working environment.

3. Durable and Long-Lasting, Ensuring Extended Service Life. The glass fiber impeller is integrally molded, offering stiffness and yield strength similar to steel, ensuring a long service life. The housing is made of resin and is protected by an anti-ultraviolet rubber shell, guaranteeing its longevity.

4. Utilizing oil-bath type base bearings and enclosed oil tanks, the bearings and shafts are protected from acidic and alkaline gas corrosion, extending their service life and reducing the frequency of malfunctions.

Causes and Solutions for Faults in Explosion-Proof High-Pressure Fans:

1. Fault Phenomenon

The motor fails to start, even when unloaded, and it slowly increases speed with a humming sound; the motor smokes and heats up, emitting a burning odor.

2. Inspection Results

After removing the motor end cover, it can be observed that 1/3 or 2/3 of the pole winding on the winding end is burnt or has turned blackish-brown.

3. Cause of the Failure and Solution Method

(1) A fuse circuit in the motor power supply circuit experienced poor contact or mechanical damage, resulting in a phase fuse failure.

(2) Different specifications of three-phase fuse in the motor power supply circuit resulted in blown fuses of smaller capacity. Fuses of the same specification should be replaced based on the motor's power rating.

(3) Switches in the motor power supply circuit (disconnect switches, rubber cover switches, etc.) are not in good contact with the contactors (burned or loose). Repair and adjust the moving and static contacts to ensure proper contact.

(4) Identify and securely reconnect the broken phase of the circuit.

(5) Poor welding between motor winding wires caused poor contact. Carefully inspect and securely weld the motor winding connections.
