Liquid ring vacuum pump for vacuum degassing?
The vacuum degassing machine is a device to remove the non-condensing gas contained in the feed fluid by vacuum suction.
What are the aspects of the degassing process?
Degassing of liquid, paste and high moisture products is one of the most important applications of modern vacuum technology in many industries. The use of vacuum technology to remove gas, steam and water in processed products is conducive to improving product quality. Degassing during plastic extrusion is one example. The vaporized water and gas from the plastic melt distillate are extracted directly from the screw area of the extruder, greatly improving the structure and physical properties of the product.
A series of standardized central vacuum systems for extruding processes are provided with separators or filters for condensing or separating steam or process gas from the extruder. Our project engineers will consider your requirements and recommend an exact matching vacuum system based on your extruder production capacity and type of raw materials. We supply vacuum solutions for all degassing processes. We provide a wide range of vacuum systems for degassing use in food processing. These vacuum pumps can be optimized for any process and reach the highest hygiene standards.
The vacuum system used for degassing steel requires special requirements: special problems due to high temperature of steam or gas and a lot of dust. Our vacuum system is completely oil-free and USES the latest technology, so it can operate in such harsh environments. EVP vacuum equipment services hundreds of enterprises, degassing field experience better than competitors.
Our specialty is vacuum degassing extruders. The extruder has economic benefits and does not need to undergo the time-consuming and energy-consuming pre-drying treatment. What vacuum pump does the vacuum degassing extruder use?
Liquid ring vacuum pump of working principle
2BV5-110 type liquid ring vacuum pump impeller 3 is eccentrically installed in the pump body, starting to inject a certain height of liquid into the pump, so when impeller 3 rotating, water by centrifugal force in the pump body wall formed a rotating liquid ring 1, the inner surface of the lower liquid ring and hub, along the direction of the arrow rotation, in the first half of the process, 2BV5-110 type liquid ring vacuum pump water ring inner surface gradually separated from the hub, so between the impeller blade and the liquid ring formed a closed space, as the impeller rotating, the space gradually expanded, the space gas pressure is reduced, the gas is sucked from the disc inlet; During the latter half turn, the inner surface of the water ring is gradually close to the hub, the space between the blades is gradually reduced, and the space gas pressure is increased. When the air pressure is higher than the exhaust pressure, the air between the blades is expelled from the disc outlet. Space between each roll a week, so impeller blade suction exhaust time, a lot of space work ceaselessly, 2bv5-110 liquid ring type vacuum pump is pumping or compress gas continuously.
2BV5-110 type liquid ring vacuum pump in the process of work, work to produce heat, will make the working liquid ring heating, at the same time part of the water and gas is drained around, therefore, in the process of work, must constantly give the pump liquid supply, to cool and replenish the water consumed in the pump, to meet the working requirements of the pump.
When the gas discharged by the liquid ring vacuum pump is no longer used, the exhaust port of the liquid ring vacuum pump is connected with a gas-water separator. After the exhaust gas and part of the water are discharged into the gas-water separator, the gas-water is separated and the gas is discharged from the exhaust pipe. With the extension of working hours, the working temperature of the water will continue to rise, then need to supply cold water from the pipes, in order to reduce the work of water temperature, to ensure that the pump can achieve the required technical requirements and performance indicators.
When liquid ring type vacuum pump used as compressor, pump outlet wind water separator, air water mixture into the gas water separator automatically after points, gas from the exhaust pipe to the required system work after water separator into 2 bv liquid ring type vacuum pump. Compressed gas, working water is easy to heat, water from the pump outlet, the temperature will become higher, by the water supply pipe constantly supply cold water. To supplement is free of water, at the same time, the cooling effect, make the job of water temperature is not too high, thus ensuring the compressor performance, danone technical indicators, with technological requirements.
