1、 Innovative breakthroughs in structural design
Symmetrical construction of double suction impeller
The impeller of the dual port suction slurry pump adopts a "back-to-back" combination structure, with two suction ports symmetrically distributed at both ends of the impeller, and the medium enters the impeller from both sides simultaneously. This design fundamentally solves the vibration and wear problems caused by axial force imbalance in traditional single suction impellers compared to the single-sided water inlet method of single suction pumps, achieving hydraulic symmetry and improving the stability of pump operation.
Integrated pump casing for simplified maintenance
Some double suction slurry pumps (such as JHL series) adopt a vertical single pump shell structure, eliminating the complex outer shell of traditional double shell pumps while retaining the overcurrent advantage of double suction impellers, balancing structural compactness and easy maintenance. For example, by optimizing the flow channel design, the pump body can achieve rapid maintenance of the rotor components without disassembling the pipeline, solving the complex pain points of repairing double shell pumps.
2、 Technical upgrade at the level of performance optimization
The multiplier effect of traffic and efficiency
Under the same impeller diameter, the flow rate of the dual port suction design can reach twice that of a single suction pump. This feature enables in high flow demand scenarios, there is no need to rely on large-sized pump bodies or multi-stage impellers, and the "small-sized high-speed" configuration can meet the working conditions, significantly reducing equipment volume and manufacturing costs.
Synergistic improvement of anti cavitation and wear resistance performance
The inlet flow velocity of the double suction impeller is relatively low, and the flow channel design optimized by fluid dynamics (CFD) can effectively reduce the turbulence and cavitation of the medium at the inlet of the impeller. For example, the JHL series double suction slurry pump uses high chromium wear-resistant alloy materials for the overcurrent components, further enhancing its resistance to coarse particles and high concentration slurry, and extending the life of vulnerable parts.
3、 Adaptive innovation in application scenarios
Multi domain adaptation for complex working conditions
The dual port suction slurry pump is widely used in strong abrasion scenarios such as metallurgy, mining, and coal due to its high flow rate and low vibration characteristics. For example, in the coal washing industry, the improved single shell double suction pump can balance the transportation efficiency of weakly abrasive slurry with the convenience of equipment maintenance; In the field of environmental protection, its anti clogging design (such as a semi open impeller) can effectively handle media containing large-diameter solid particles.
Optimization of energy consumption and cost balance
Compared to traditional single suction pumps, the dual port suction design reduces energy consumption by reducing speed requirements and improving volumetric efficiency. Meanwhile, some models (such as the EZJ series) adopt a dual pump casing structure, with the inner pump casing made of high wear-resistant materials and the outer pump casing made of low-cost cast iron, which ensures wear resistance while controlling manufacturing costs.
Summary: Innovative Value of Dual Port Inhalation Design
The dual port suction slurry pump solves the contradiction between stability and economy of traditional pump types under high flow and high abrasion conditions through triple innovation of structural symmetry, efficient performance, and application scenarios. Its core advantage lies in the innovation of impeller design, which realizes the collaborative optimization of "flow rate increase energy consumption reduction life extension", providing a more adaptable solution for industrial fluid transportation.
