Detailed application of vertical long axis suspended semi submersible sump pump in direct pumping and transportation of waste liquid in acid washing production line

The vertical long axis suspended semi submersible sump pump, with its core characteristics of no shaft seal leakage, strong corrosion resistance, and deep pool direct extraction, has become the mainstream choice for the direct extraction and transportation of waste liquid in acid washing production lines. It fully meets the demanding requirements of direct extraction and transportation of waste liquid in acid washing production lines. The specific application details are as follows:
⚙️  Core direct pumping and conveying scene of pickling production line
·Direct pumping and transportation of acid pickling tank waste liquid: Directly connected to acid pickling production lines in metallurgy, hardware, electroplating and other industries, without the need for intermediate transfer tanks, high concentration hydrochloric acid/sulfuric acid/nitric acid pickling waste liquid is directly extracted from the tank, achieving closed and direct transportation of waste liquid from the production line to subsequent treatment processes.
·Direct extraction of acid pickling waste liquid from the low-level pool: The waste liquid is directly extracted from the bottom of the underground low-level waste liquid collection pool provided by the production line. The customized long axis version can adapt to the liquid extraction needs of pools over 6 meters deep, and can be started directly without the need for pumping, avoiding the deposition and scaling of waste liquid in the pool.
·Acid washing waste liquid regeneration and reuse transportation: transported to the acid washing waste liquid regeneration and recovery process, the waste acid is directly transported to the acid recovery device, and the whole process is sealed without leakage, ensuring the continuous and stable operation of the waste acid recovery system.
·Emergency waste liquid extraction from acid pickling line: As an emergency backup pump for acid pickling production line, it can quickly extract waste liquid from the acid pickling tank, cope with sudden working conditions such as production line maintenance and waste liquid leakage, and avoid safety and environmental accidents caused by the overflow of strong acidic waste liquid.
✅  Core advantages of scene specific adaptation
·Leak free safety guarantee: With no exposed mechanical seal design, it effectively prevents the leakage of strong acidic acid pickling waste liquid from the source, avoids the volatilization and diffusion of acid mist, and fully meets the safety and environmental protection requirements of the pickling workshop.
·Outstanding strong corrosion resistance: The overcurrent components can be made of fluoroplastic alloy, high chromium wear-resistant alloy, or duplex steel material, which can withstand the corrosion of strong acidic media and the long-term erosion of iron oxide scale particles in acid pickling waste liquid, and is suitable for the complex harsh working conditions of strong corrosion and high abrasion.
·Higher direct extraction efficiency: Directly extract waste liquid from the pickling tank/low-level waste liquid pool without the need for pumping, with a short conveying process and no residual waste liquid in intermediate links, greatly improving waste liquid conveying efficiency and reducing waste liquid volatilization loss.
·Convenient and safe operation and maintenance: The vertical structure is directly installed on the top of the waste liquid pool, occupying a small area. The rotor can be extracted for maintenance without disassembling the pipeline, greatly reducing the risk of operation and maintenance personnel coming into contact with strong acidic waste liquid.
Key points for scene specific selection
·When transporting high concentration and strong oxidizing acid pickling waste liquid, it is preferred to use overcurrent components coated with perfluoroplastics to avoid rapid corrosion and perforation of ordinary metal materials.
·When the medium contains a large amount of solid particles of iron oxide scale, the guide bearing must be equipped with an external clean cooling water lubrication system, and a hard alloy shaft sleeve should be selected to avoid particle wear and bearing failure.
·The submerged insertion length of the pump under direct pumping conditions must be 300-500mm lower than the lowest liquid level at the bottom of the tank to ensure stable extraction of waste liquid even at extremely low liquid levels and avoid equipment damage caused by air suction.
At present, the vertical long axis suspended semi submersible sump pump, which is suitable for the direct pumping and transportation of waste liquid in acid pickling production lines, has a mainstream flow rate coverage of 6.3~400m ³/h and a head of 5~80m. There are already a large number of mature landing cases of vertical long axis suspended semi submersible sump pumps in the metallurgical and hardware acid pickling industries, fully meeting the strict requirements of direct pumping and transportation of waste liquid in acid pickling production lines.
