horizontal slurry pump

The strong oxidizing property (ORP＞+1000mV) and crystallization tendency of sodium chlorate solution make it a "pumping killer", while the fluorine-lined pump reinforced with ultra-high molecular weight polyethylene (UHMWPE) has achieved a breakthrough performance improvement through material composite innovation.   ① Performance leap brought by material composite   1. Anti-wear revolution   1.1 The addition of UHMWPE (molecular weight ≥3 million) increases the wear resistance by 8 times (ASTM D4060 test)   1.2 The ability of the impeller edge to resist particle erosion is 3.2 times that of the ordinary F46 pump (actual measurement under the condition of 15% concentration containing crystal slurry)   2. Temperature-corrosion synergistic resistance Temperature range Pure F46 performance UHMWPE Enhanced Performance Below 80℃ Annual corrosion: 0.008mm 0.005mm 80-120℃ Prone to stress cracking Maintaining the complete lattice structure Short-term exposure up to 150°C Irreversible deformation Can withstand 4 hours of thermal shock   ② Comparison of key engineering parameters   1. Life cycle:   1.1 Continuous operation time: 8000h for ordinary fluorine-lined pump vs 25000h for ultra-high molecular fluorine-lined pump   1.2 Overhaul interval extended to 5 years (under sodium chlorate crystallization conditions)   2. Energy efficiency performance:   2.1 Volumetric efficiency > 92% 2.2 Save 15-18% electricity compared to ordinary fluorine-lined pumps   ③ Full cost economic verification   1. Initial investment: 40% lower than Hastelloy pumps and 25% higher than ordinary fluorine-lined pumps   2. Comprehensive benefits:   2.1 Spare parts consumption reduced by 60%   2.2 Sudden downtime losses reduced by 92%   Case study: After a company in Jiangxi used this pump type to transport sodium chlorate, the annual maintenance cost of a single line was reduced from 280,000 to 65,000, and the production capacity was increased by 23%. (China Chlor-Alkali Industry Association 2025 Blue Book) This case can be found.

A slurry pump is a centrifugal pump widely used for transporting liquid mixtures containing solid particles (i.e., slurry). Working principle: It relies on the rotating impeller to do work on the liquid, enabling the liquid to obtain energy and thus realizing the transportation of slurry. When the impeller rotates, the liquid between the blades is thrown out under the action of centrifugal force, and a low - pressure area is formed at the center of the impeller, so that new slurry is continuously sucked in, and then the slurry is continuously transported to the destination. For example, during the ore - dressing process in a mine, the ore pulp is sucked into the slurry pump and then transported to the next process through the rotation of the impeller. Structural features: Impeller: It is a key component of the slurry pump, and it has various design forms to adapt to different working conditions. Common ones include closed - type, semi - open - type and open - type impellers. The closed - type impeller has high efficiency and is suitable for transporting relatively clean slurry with small and uniform particles; the semi - open - type impeller can handle slurry with certain particle size and concentration; the open - type impeller can cope with large - particle and high - concentration slurry, but its efficiency is relatively low. Pump casing: It is usually in the shape of a volute. Its function is to collect the liquid thrown out from the impeller and gradually convert the kinetic energy of the liquid into pressure energy, so that the slurry can be transported under a certain pressure. Shaft sealing device: It is used to prevent slurry leakage and air from entering the pump. Common shaft sealing methods include packing seal and mechanical seal. The packing seal has a simple structure, but the sealing effect is relatively poor, and there may be a small amount of leakage; the mechanical seal has better performance, can effectively reduce leakage, but has a higher cost and more stringent requirements for installation and maintenance. Application fields: Mining industry: It is used to transport ore pulp in the ore - dressing process, including various metal and non - metal ore dressing plants, such as copper mines, gold mines, iron mines, coal mines, etc. For example, during the copper ore dressing process, the ore pulp containing copper ore particles is transported from the grinding mill to the flotation machine or other ore - dressing equipment. Metallurgical industry: In metallurgical production, it is used to handle slurry containing solid particles such as waste slag and tailings. For example, the discharge and transportation of blast furnace slag in an iron and steel plant during iron making. Power industry: It is used to transport fly - ash slurry in thermal power plants, etc., transporting the burned fly - ash slag to storage or treatment sites. Coal industry: In the coal washing process, it is used to transport coal - slurry water, etc., realizing the separation of coal and impurities and subsequent processing.
