Solid-liquid Two-phase Flow Conveying Characteristics Of Vertical Slurry Pumps

The solid-liquid two-phase flow conveying characteristics of vertical slurry pumps are mainly reflected in their design principles, structural characteristics and application occasions. The following is a detailed description of their solid-liquid two-phase flow conveying characteristics: I. Design principle Vertical slurry pumps are designed with advanced solid-liquid two-phase flow theory. The geometric shape of its flow-through components matches the flow state of the medium to reduce local and along-the-way hydraulic losses such as eddy currents and impacts. This design reduces the wear of flow-through components, improves hydraulic efficiency, and reduces operating noise and vibration. II. Structural features 1. Vertical single-stage single-suction cantilever centrifugal pump structure: The slurry pump has this special structure, which enables it to handle solid-liquid mixtures more efficiently. 2. Semi-open impeller and stirring blades: The impeller is semi-open, and stirring blades are provided at the extension of the impeller suction side, which helps to improve the flow state of the medium and improve the conveying efficiency. 3. High-strength material: The flow-through parts are made of high-hardness alloy cast iron, which has high wear resistance, corrosion resistance and impact resistance, thus extending the service life. 4. Shaft seal-free design: The slurry pump usually works immersed in a pool or pit, without shaft seals and shaft seal water, which reduces maintenance costs and failure rates. III. Application occasions and conveying characteristics Vertical slurry pumps are widely used in mining, metallurgy, electricity, coal, chemical industry, building materials and other industries to convey abrasive and corrosive slurries containing solid particles. The maximum weight concentration of its solid-liquid mixture can reach 45% for slurry and 60% for ore slurry. The specific conveying characteristics are as follows: 1. High flow: The slurry pump can convey a large amount of solid-liquid mixture to meet the needs of various industrial applications. 2. High pressure: During the conveying process, the slurry pump can maintain a high pressure stability to ensure the smooth conveying of the medium. 3. Wear resistance: Due to the use of high-strength materials such as high-hardness alloy cast iron, the slurry pump has high wear resistance and can operate stably for a long time. 4. Corrosion resistance: The material of the flow-through parts of the slurry pump has excellent corrosion resistance and can resist the erosion of corrosive media. Vertical slurry pumps play an important role in the field of solid-liquid two-phase flow transportation with their special design principles, structural characteristics, wide range of applications and transportation characteristics.
