SLPWDL Multi-suction Vertical Sewage Pump

What are the structural features of SLPWDL multi-suction vertical sewage pump?

SLPWDL multi-suction vertical sewage pump is an innovative high-performance pump product. Its structural design adopts a vertical cylinder form, and the motor and pump body are coaxially arranged. This design not only makes the equipment compact, but also effectively reduces the floor space, making it easy to install and maintain. The multi-suction inlet structure of the pump body has been optimized, and multiple symmetrical or annularly distributed suction ports are used to ensure uniform suction of the liquid, thereby significantly improving the distribution stability of the fluid inside the pump body. This technology effectively avoids problems such as cavitation, impact and vortex caused by excessive local flow velocity, and has become the core competitive advantage of this series of pumps compared to traditional sewage pumps.
In terms of impeller design, SLPWDL multi-suction vertical sewage pump adopts a large channel anti-blocking design, which can smoothly pass solid particles and long fiber materials with larger diameters. This design significantly improves the pump's ability to operate reliably under harsh working conditions. The impeller material is made of high-strength, corrosion-resistant and wear-resistant cast iron or alloy steel, combined with Jiangsu Double Wheel Pump Machinery Manufacturing Co., Ltd.'s rich experience in the field of wear-resistant materials to ensure the structural strength and durability of the pump during long-term operation. In addition, the flow guide components are optimized and designed through computational fluid dynamics (CFD) simulation, which effectively reduces hydraulic losses and improves the operating efficiency of the entire pump.
In terms of pump shaft structure, SLPWDL multi-suction vertical sewage pump adopts a high-precision long shaft design, equipped with a multi-channel bearing support system and an independent lubrication system to ensure the coaxiality and stability of the pump shaft during long-term high-load operation. For typical use scenarios such as deep wells or large water collection tanks, Jiangsu Double Wheel Pump Machinery Manufacturing Co., Ltd. has also specially designed an optional guide bearing structure to further improve the running stability of the equipment in large head and large flow systems.
In terms of sealing system, SLPWDL multi-suction vertical sewage pump abandons the design of traditional mechanical seal or packing seal, inherits the profound accumulation of Jiangsu Double Wheel Pump Machinery Manufacturing Co., Ltd. in non-sealed self-priming pump technology, and innovatively develops auxiliary isolation chamber and sealing barrier design. This design effectively prevents solid matter and corrosive media in sewage from invading key structural components, significantly improves the reliability of the whole machine, and reduces the subsequent maintenance cost.
In the connection structure design between the pump body and the motor, SLPWDL adopts a direct connection structure, which eliminates the assembly link of the traditional coupling, further simplifies the equipment structure, reduces transmission loss, and improves the overall operating efficiency. In terms of motors, the company provides full voltage level configurations from 380V to 10KV, and can customize a variety of motor solutions such as explosion-proof and high-temperature types according to the specific needs of customers, greatly broadening the scope of application of the product.

What are the design features of the suction port of SLPWDL multi-suction vertical sewage pump?

In the field of modern sewage treatment, traditional sewage pumps face many challenges, such as uneven water inlet caused by a single suction port, severe fluid disturbance, and blockage caused by impurity concentration, which seriously affect the operating efficiency and stability of the pump.
The suction port of SLPWDL multi-suction vertical sewage pump adopts a multi-channel layout with symmetrical distribution or annular distribution to ensure that the sewage forms a uniform diversion state before entering the pump cavity. This design effectively reduces the problem of high local flow velocity, avoids cavitation, turbulence and abnormal wear of the pump structure caused by concentrated fluid impact, thereby improving the overall working efficiency and operating stability of the pump.
In addition, the multi-suction suction port design of SLPWDL not only optimizes the water inlet flow field, but also enhances the adaptability of the pump. Through the scientifically designed diversion channel, the suction ports are interconnected, and the system can automatically adjust the water inlet of each suction port according to the actual working conditions to achieve the effect of self-balancing flow. This design significantly improves the hydraulic efficiency of the pump, ensuring that it can maintain excellent performance under different working conditions.
In view of the challenges of high solid content and long fiber impurities commonly found in sewage, the suction port design of SLPWDL multi-suction vertical sewage pump fully considers the capacity of large channels and the efficiency of impurity diversion. The suction port diameter of the pump can be flexibly configured according to the flow level, and the maximum water inlet diameter can be Φ1200mm, so that larger solid particles can be passed smoothly. This design significantly improves the reliability of the equipment in industrial and urban sewage treatment, and ensures the high efficiency of the pump in treating complex sewage.
In terms of material selection, Jiangsu Double Wheel Pump Machinery Manufacturing Co., Ltd. uses self-developed wear-resistant materials and anti-corrosion alloys, and performs special spraying and surface treatment on the inner wall of the suction port. This treatment effectively delays wear and corrosion, ensures the long-term stable operation of the equipment, and further improves the service life and maintenance efficiency of the pump.
From a structural perspective, the suction port of SLPWDL multi-suction vertical sewage pump adopts a modular design as a whole, which is convenient for on-site installation, disassembly and maintenance. The multi-suction layout provides flexible space for the later modification and upgrading of the pump body. Customers can choose different forms of water inlet combinations according to actual working conditions, such as double-suction symmetrical type, three-suction evenly distributed type, four-suction ring-distributed type and other structural configurations.
