In recent years, China has launched many large-scale capital construction projects and technological transformation projects. The actual projects of these projects require a large amount of PVC materials, especially real estate, which has further promoted the development of the PVC industry. According to the requirements of the chlor-alkali industry Statistics show that China produced 4.1 million tons of PVC last year and 200 tons of imported materials. According to the forecast of the industry, the national demand in 2005 will reach 8 million tons, and by 2010 it will reach 15 million tons precisely because of the rapid increase in demand, making China's chlor-alkali industry enterprises to expand production expansion and near One or two years a lot of new businesses. The development of chlor-alkali enterprises, water and air pumps and water ring compressor must be supporting j to extract and compress acetylene and hydrogen water ring vacuum pump and water ring compressor in the past but also the largest 30m3 / min, and now with an annual output of 100,000 tons Caustic soda and 100,000 tons of PVC companies need water ring vacuum pump and water ring compressor up to 70m3 / min. What needs to be specially introduced here is precisely because of the development of this industry, to promote and speed up the development and production of high I-force water ring compressors. For a long time, China's water ring compressor is generally when the suction pressure of 1 atm or slightly lower than the pressure, the exclusion of pressure O.1MPa, the compression ratio of 2, the production of individual enterprises to exclude the pressure of 25MPaG water ring Compressor, but only 1 to 2 specifications. In order to adapt to the production of polyvinyl chloride, the former major equipment office of the State Council proposed in the "85" major technological equipment research project - the research and development of an equipment with an annual output of 4 tons of low-polymerization degree polyvinyl chloride device, proposed the recovery of vinyl chloride water ring compressor Research topics, this recovery of vinyl chloride monomer water ring compressor requires suction pressure at atmospheric pressure or micro negative pressure, the discharge pressure to reach O.55 ~ 0.6MPaG, and the displacement to reach 700m3 / min. After several years of hard work, our company passed the technical appraisal organized by the former Ministry of Machinery Industry in December 1996, and the customer technology has reached the key requirements. On the basis of this product, our company has developed a series of products, displacement from 90m3 / min ~ 2000m3 / h. Since this equipment is one of the key equipment in the PVC industry, under the circumstance of the large PVC project in China in recent years, the water ring compressor has been popularized and applied, completely replacing the import.
The working principle of a High Flow Peristaltic Pump like a snake swallowing an egg. The hose is constantly squeezed through the roller to make the hose generate pressure and push the liquid forward. Our designers make the Peristaltic pump head and hose fit perfectly by designing precise roller size and pump head structure. So as to achieve the purpose of accurate liquid metering transmission or filling
1. Clean and pollution-free: the fluid only passes through and touches the peristaltic pump hose.
2. High precision: constant current, reproducibility of up to 0.5%, and flow can be precisely adjusted.
3. Low shear force: It is an ideal tool for conveying shear-sensitive and corrosive fluids.
4. Corrosion resistance: it can transport various fluids, such as organic solvents and corrosive liquids.
5. Idling and dry operation: air or gas-liquid-solid three-phase mixed transportation can also be transported.
6. Possess self-priming ability: self-priming, no need to fill the pump, no need to empty.
7. With stop valve function, no siphon, no seals, stop valve and check valve function.
8. Two-way conveying function: reverse pumping and back-suction functions can be realized by changing the direction of the pump runner.
9. Simple maintenance: only need to replace the peristaltic pump hose, no valve and seal replacement.
