Jiangsu Feiyue Pump Industry Co., Ltd.-Desulfurization slurry pump

Desulfurization slurry pump

Description：

The dual phase process pump is a new generation of high-efficiency desulfurization pumps developed based on the successful design and manufacturing experience of ZM series slurry pumps, and tailored to the characteristics of pumps used for flue gas desulfurization in China. It absorbs advanced technology from similar products at home and abroad and is carefully researched. The large flow range of the pump can reach 12000mm ³/h, and the head of the pump is generally below 100m, covering all pump operating conditions for desulfurization systems. It can be used as a large-scale slurry circulation pump for absorption towers, limestone slurry delivery pump, gypsum slurry discharge pump, recovery pump, pit pump, etc.

Applicable scenarios

Slurry pH value: 2.5-13

Gas ion concentration: ≤ 60000ppm

Weight concentration: ≤ 60%

Medium temperature: ≤ 120 ℃

Performance and material characteristics

The hydraulic design adopts computer-aided design and two-phase flow theory design.

The pump has high efficiency, long service life, and reliable operation.

The overcurrent components are made of all metal wear-resistant chromium nickel alloy material, which balances wear resistance and corrosion resistance. The surface intergranular gap is small, and it has excellent resistance to chloride stress corrosion cracking and higher mechanical strength.

High operational reliability, the all metal pump overcomes the disadvantages of non-metallic pump liners such as detachment, tearing, and deformation.

The hydraulic friction loss is small, and the efficiency is more than 3% higher than that of non-metallic pumps with the same parameters.

All metal pumps are easy to control and ensure in terms of size, with high surface smoothness of parts, small clearance between parts, high volumetric efficiency, and a comprehensive efficiency that is more than 5% higher than non-metallic pumps.

The overcurrent components have a long service life, and the metal protective plate has a stronger ability to withstand shear sliding wear than general non-metallic materials, and can withstand long-term shear wear.

The dynamic wear resistance is 0.008-0.08mm years, with high tensile strength, and can maintain constant performance under long-term abrasion conditions.

Shaft seal type

All shaft seals are equipped with mechanical seals. Our company offers two types of mechanical seals: those with shaft seals and those without shaft seals.

■ With shaft seal water type

Combination mechanical seal, with a shaft seal water flow rate of 0.1-1% of the pump flow rate, but not less than 1m ³/h; The water pressure of the shaft seal is equal to half of the pump outlet pressure.

■ Shaftless water type

Water free medium self flushing mechanical seal with unique structure and good water-saving effect.
