Product details
The unique structure of QLX-D single blade submersible spiral centrifugal pump determines its superior conveying performance. Its core component is the spiral centrifugal impeller, which consists of two parts: the spiral part and the centrifugal part. The front end of the impeller is shaped like a sickle. The spiral part provides a positive displacement thrust, which forms a bending force at the axial extension, causing the water flow at the inlet to enter the pump body along the tangential direction of the impeller rather than at a right angle or angle to the impeller. This not only reduces the shear effect of the impeller on the incoming water flow, reduces hydraulic losses, but also lowers the net suction head of the pump, improving its resistance to cavitation.
Characteristics of Spiral Centrifugal Impeller Pump
1. True non clogging performance: Spiral centrifugal pumps have extraordinary non clogging performance. The open channel of the pump has the characteristics of high efficiency and no blockage, making it easier to transport large volumes of solids and long fiber materials. Ordinary so-called unobstructed centrifugal pumps often get caught by the edges of the blades or stuck or blocked between the inlet and outlet when long fibers and solids enter the channel, causing mechanical failures. Installing a spiral centrifugal impeller eliminates these issues. The spiral impeller will automatically screw into the soft solid, preventing the filling material from blocking at the inlet, and the inner wall of the suction port and the back of the impeller are also designed with reverse threaded grooves to prevent fiber accumulation.
2. Soft conveying medium: Another advantage of the spiral design is' soft conveying ', which means that solid matter flows through without hitting any part inside the pump. This advantage applies to the following fields: transporting active loose substances, which can maintain their original physical state, and loose substances will not be torn or broken. The oil in the lotion can maintain its specific characteristic state. Suspended fibers will not be twisted or tangled. Fragile items such as tomatoes, live fish, etc. will not be damaged.
3. Outstanding operating curve: high efficiency=low operating cost, steep performance curve=smooth operation, low net suction head=high self-priming capacity, smooth power curve=no overload area, high speed=compact structure
4. High solid content medium processing capability
5. Adopting adjustable wear-resistant lining: Optional wear-resistant lining is an ideal choice for applications with severe wear. When wear occurs, only one lining needs to be replaced, without the need to replace the entire shell, which is both convenient and economical.
6. Adopting famous brand heavy-duty bearings and high-quality mechanical seals: using international famous brand heavy-duty bearings and high-quality specialized mechanical seals, as well as other world's best components. Therefore, it is possible to ensure continuous operation with the lowest maintenance and repair costs.
Application Fields
1. Municipal drainage (pump stations can eliminate grilles) and various process links of sewage treatment plants
2. Chemical industry: pumping of liquids containing crystalline substances, oily wastewater (without turbidity), and without changing the properties of the medium
3. Food industry and fisheries: transportation of fruits, vegetables, live fish, poultry organs after slaughter, etc
4. Paper industry: transporting long fiber pulp or recycled pulp
5. Transporting slag, no mud during excavation tunnel construction, no construction site water accumulation, etc
6. Steel plant: Transporting wastewater containing solid materials such as iron filings and sheets
7. On a suction dredger used for dredging river channels
