SLW Series Horizontal Centrifugal Pump

What are the pump body structural features of the SLW series horizontal centrifugal pump?

The SLW series horizontal centrifugal pump takes full account of the stability, durability and convenience of maintenance of the equipment in the design of the pump body structure, showing the industry-leading technical level. The SLW series horizontal centrifugal pump of Jiangsu Double Wheel Pump Machinery Manufacturing Co., Ltd. adopts a horizontal structure, which significantly saves the space occupied by the equipment and simplifies the installation, maintenance and overhaul process of the pump. This design makes the pump body arranged horizontally. Compared with the traditional vertical pump, the horizontal pump provides a more compact solution in structure, which is particularly suitable for application scenarios with limited space. In addition, the uniform weight distribution of the pump body effectively reduces the vibration and noise during operation, greatly improving the stability and service life of the equipment.
In terms of material selection, the pump body is made of high-strength alloy or stainless steel, showing excellent corrosion resistance and wear resistance, and can operate at high load for a long time under harsh working conditions. Especially in applications involving corrosive chemical media or high-temperature liquids, the SLW series horizontal centrifugal pump of Jiangsu Double Wheel Pump Machinery Manufacturing Co., Ltd. relies on the selection of high-quality materials to ensure that the pump body maintains long-term reliability under various extreme conditions. This feature is particularly important in the petroleum, chemical and other industries, and meets the strict requirements for pump body materials in terms of corrosion resistance and high temperature resistance.
In terms of the design of the flow channel in the pump body, the SLW series horizontal centrifugal pump adopts an optimized flow channel shape to ensure the smooth flow of the fluid in the pump, significantly reducing energy loss, thereby improving the overall efficiency of the pump. This flow channel design effectively avoids the vortex phenomenon in the liquid flow, reduces energy consumption, and thus reduces operating costs. At the same time, the optimized design of the flow channel enhances the self-priming ability of the pump, so that the pump can quickly expel air and form a stable liquid flow when starting, ensuring the efficient start-up and continuous operation of the pump.
The internal structure of the SLW series horizontal centrifugal pump has been precisely calculated and designed to achieve efficient liquid transportation, especially when dealing with large flow and high head liquids, it can maintain stable output performance. In the design of the pump body, special attention is paid to the application of fluid dynamics to ensure that the pump can maintain low energy loss and high transmission efficiency when running at high speed. The flow channel and impeller shape of the pump have been strictly tested to ensure operational efficiency and durability.

How big is the performance difference of SLW series horizontal centrifugal pumps at different installation heights

The performance of SLW series horizontal centrifugal pumps is affected by many factors, among which the installation height is a key parameter. In the process of liquid transportation, the installation height of the pump not only affects the suction and head of the pump, but also directly affects the efficiency, power consumption and service life of the pump. The installation height refers to the vertical distance of the pump installation position relative to the liquid level. This parameter directly determines the water absorption capacity of the pump and its performance in actual work.
The installation height has a significant impact on the suction head of the SLW series horizontal centrifugal pump (that is, the maximum height at which the pump can effectively absorb water). The suction head of the pump is restricted by the working principle of the pump body and the principle of fluid dynamics. The pump body design of the SLW series horizontal centrifugal pump adopts an optimized flow channel structure and an efficient impeller design, which enables it to work stably under a larger suction head. However, when the installation height is too high, the water absorption performance of the pump will be limited, resulting in a reduced suction head. This is because, as the installation height increases, the pump needs to overcome more air and liquid resistance, especially at startup, the pump's self-priming ability may be affected, resulting in the inability to effectively suck in the liquid, and even possible idling or failure.
Jiangsu Double Wheel Pump Machinery Manufacturing Co., Ltd. pays special attention to the self-priming ability of the pump in the design of the SLW series horizontal centrifugal pump. By optimizing the structure of the pump body and impeller, this series of pumps has a strong self-priming ability. However, this self-priming ability is still affected by the installation height. At a higher installation height, despite the optimized pump body design, the pump still takes longer to expel the inhaled air to restore normal liquid flow. Therefore, when the user is in a high installation position, additional auxiliary devices, such as a water diversion pipe or a dedicated starting system, may be required to ensure the normal operation of the pump.
In addition, the installation height also has a significant impact on the head (i.e., the pressure that the pump can generate) of the SLW series horizontal centrifugal pump. The pump head refers to the maximum vertical lifting height of the pump through the liquid. This indicator is closely related to the density of the liquid, the operating speed of the pump, and the structural design of the pump body. At a lower installation height, the SLW series horizontal centrifugal pumps of Jiangsu Double Wheel Pump Machinery Manufacturing Co., Ltd. can give full play to the head capacity of its impeller and provide higher pressure and flow. However, as the installation height increases, the resistance to liquid transportation also increases, resulting in a decrease in head. At a high installation position, the liquid needs to overcome more gravitational potential energy, and the pump body needs to consume more energy to overcome these resistances, which ultimately leads to a decrease in the pump's head performance.
In order to solve this problem, Jiangsu Double Wheel Pump Machinery Manufacturing Co., Ltd. has optimized the design of the SLW series horizontal centrifugal pumps in many aspects, especially in the design of the impeller, by reasonably selecting the impeller material, the number and angle of the impeller blades, and further improving the pump's head capacity. This design alleviates the problem of reduced head performance at high installation heights to a certain extent. However, even so, the pump's head will still be different at different installation heights. Therefore, when selecting and installing the SLW series horizontal centrifugal pumps, users must reasonably adjust the installation height according to the actual use environment to ensure the operating status of the pump.
