Axial submersible pumps, such as the ZQ and HQ series, along with the Francis submersible pump, are designed as a fully integrated system consisting of the pump body, impeller, submersible motor, and other essential components. The motor and pump head are aligned on the same axis, forming a single unit. A mechanical seal is used to separate the motor from the pump, ensuring a watertight connection. The cable inlet is sealed using an appropriate gland, maintaining the motor in a fully enclosed and protected environment. These pumps operate entirely submerged in water, featuring internal leakage detection and temperature protection systems for safe and reliable performance. They are equipped with adjustable blades, allowing for a wide range of flow and head capabilities.
The product complies with the JB/T 10179-2000 standard for Francis and axial submersible pumps. These pumps are widely used in agricultural irrigation systems, urban flood control, water supply projects, and light sewage drainage. They are especially suitable for applications where flow and head requirements vary significantly.
Key features of the ZQ and HQ series include:
1. **Professional and Reliable Design**: Specifically engineered for high-flow, low-head applications, these pumps combine advanced domestic and international pump technologies. They offer a superior alternative to traditional axial and mixed-flow pumps. With the motor and pump integrated into one unit, they provide unmatched performance when compared to conventional systems.
2. **Multi-Channel Detection and Protection**: Equipped with oil-water sensors and float switches, the system can monitor and alert in real-time, triggering shutdowns and retaining fault signals. This ensures the motor operates safely and reliably.
3. **Anti-Torque Device**: To prevent reverse rotation caused by the initial starting torque, an anti-torque mechanism is incorporated, making the operation smoother and more stable.
4. **Durable Waterproof Cable**: Featuring oil-resistant heavy-duty rubber cables with a special sealing structure at the outlet, this design prevents leaks and ensures long-term reliability. It also prevents condensation inside the motor cavity.
5. **Safe and Reliable Operation**: The pump includes two or more independent mechanical seals, with special friction materials arranged in series. This provides multiple layers of protection, ensuring a long service life and dependable performance.
6. **Easy Installation and Cost-Efficient**: As the motor and pump are combined into a single unit, there's no need for complex on-site alignment or shaft processing. This simplifies installation and reduces construction costs. The pump can be directly submerged, minimizing the structural requirements of pumping stations and saving up to 30–40% of the total project cost.
**Working Conditions:**
- Flow: 670 – 28,000 m³/h
- Head: 1.0 – 20 m
- Medium Temperature: ≤ +50°C
- Ambient Temperature: ≤ +40°C
- Motor Insulation Class: F
- Motor Protection Rating: IPX8 (suitable for water and light sewage)
These pumps are ideal for a variety of applications where efficiency, durability, and ease of installation are critical. Their advanced design and robust construction make them a preferred choice for modern hydraulic systems.
Free Running Wire Thread Insert
Free running wire thread inserts can be used to strengthen threads, giving applications a longer life. Each insert sharing the load over the entire bolt and hole, improving holding or pull out resistance. With a Wire Thread Insert installed, a more even distribution of load and stress can be achieved. Free running wire thread inserts are generally made of type 304(18-8) stainless steel wire rolled into a diamond shape cross-section.
