1. Power Supply:
Operates on a 380V, 50Hz three-phase AC power supply. The capacity of the distribution transformer should be 2–3 times the rated power of the motor.
2. Operating Temperature:
The temperature of the working medium must not exceed 60°C and should not contain flammable or explosive gases.
3. Solid Concentration:
For ash slurry: up to 45% by weight
For ore slurry: up to 60% by weight
4. Submersion Depth:
Maximum submersion depth is 40 meters. The minimum submersion should at least cover the motor.
5. Installation Position:
The unit should operate vertically while suspended from the top and properly positioned within the medium.
Users should follow the product’s operating manual for proper maintenance.
Repairs should be performed only by personnel with the necessary technical expertise and relevant knowledge.
Key maintenance points include:
1. After a period of use, the electrical insulation should be inspected to ensure it meets operational requirements.
2. If signs of low insulation resistance, damaged cables, rust, or difficulty in starting (e.g. high start-up current) are detected, the pump should be promptly inspected and repaired.
3. Improper maintenance or usage may lead to safety hazards or cause further damage to the equipment.
