Safety Precautions and Installation Guidelines

To ensure the safe and efficient operation of the 175QJB Deep Well Submersible Pump, it is essential to follow the manufacturer's guidelines and safety precautions:

• Water Quality Requirements: The pump is designed for clean water with specific parameters, including a maximum temperature of 20°C, a solid impurities content of less than 0.01%, and a pH range of 6.5-8.5. Using water that does not meet these specifications can lead to reduced performance and premature failure.
• Installation Requirements: The pump must be installed vertically and fully submerged in water, with an immersion depth not exceeding 70 meters. The distance between the pump and the well bottom should be at least 3 meters to prevent damage from sediment and debris.
• Electrical Safety: The pump requires a three-phase AC power supply of 380V/50Hz, with a tolerance of ±5% for voltage and ±1% for frequency. Proper grounding and overload protection are essential to prevent electrical hazards.

Installation should be performed by trained professionals to ensure compliance with safety standards. The pump must be filled with clean water before use, and the water charging and deflating bolts should be tightened to prevent leaks. Additionally, the pump should be equipped with a cable that meets the required specifications and an external overload protection device to safeguard against electrical faults.

Maintenance and Longevity

To maximize the lifespan and performance of the 175QJB Deep Well Submersible Pump, regular maintenance is essential. Key maintenance tasks include:

• Insulation Resistance Testing: After installation, the motor's insulation resistance should be checked to ensure it meets the required standards. Regular testing helps identify potential issues before they lead to failures.
• Visual Inspections: Periodic inspections of the pump and motor for signs of wear, corrosion, or damage are crucial. Any issues should be addressed promptly to prevent further deterioration.
• Lubrication and Cleaning: The pump's bearings and seals should be lubricated regularly, and the unit should be cleaned to remove debris and sediment that could affect performance.

Following the manufacturer's maintenance schedule and using genuine replacement parts can significantly extend the pump's service life. Hebei Aochite recommends that the pump be dismantled and inspected after one year of operation or after two years of continuous use, whichever comes first. This ensures that any worn components are replaced, maintaining the pump's efficiency and reliability.

Storage and Handling

Proper storage and handling are critical to preserving the 175QJB Deep Well Submersible Pump's performance and longevity. When not in use, the pump should be stored in a dry, indoor environment free from corrosive substances and gases. The temperature should be kept below 40°C to prevent damage from extreme heat. In cold climates, the motor cavity should be drained to prevent freezing, which could damage the internal components.

Before storage, the pump should be cleaned and dried to remove any residual water or debris. The cables should be securely tied to prevent tangling, and the pump should be protected from physical damage. Regular checks during storage can help identify any issues early, ensuring the pump is ready for use when needed.
