Henan professional production 2BV water ring vacuum pump factory

1 Introduction 2BV water ring vacuum pump (referred to as water ring pumps) is a rough vacuum pump, it can get the ultimate vacuum of 2000 ~ 4000Pa, 2BV water ring vacuum pump can also be used as a compressor, called water ring compressor is belonging to the low-pressure compressor, a pressure in the range of 1 ~ 2 × 105Pa gauge pressure. 2BV water ring vacuum pump was originally used as a self-priming pump, then gradually used in petroleum, chemical, machinery, mining, light industry, medicine and food, and many other industrial sectors. In many processes in industrial production, such as vacuum filtration, vacuum water, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum resurgence and vacuum degassing, water ring pumps are widely used. Due to the rapid development of application technology of vacuum, liquid ring vacuum pumps in the rough vacuum in access has been valued by the people. As the water ring vacuum pump in the gas compression is isothermal, it can be exhausting flammable, explosive gases, but can also dust extraction, water gas, therefore, 2BV water ring vacuum pump used increasingly. 2 works when 2BV water ring vacuum pump impeller rotating adverse economic policy, water is thrown around the impeller, centrifugal force, the water forms a closed ring shape depends on the pump chamber approximately equal thickness. The inner surface of the lower portion of the water ring box coincided with the impeller tangent to the upper surface of the water ring just in contact with the blade tip (actually leaves in the water ring for a certain insertion depth). Forming a crescent-shaped space between the impeller housing and water ring interface at this time, but the space has been divided into 2BV water ring vacuum pump impeller blades and an equal number of blades of a number of small cavities. If the lower part of 2BV water ring vacuum pump impeller 0 ℃ as a starting point, then the volume before the impeller rotating 180 ℃ when the small chamber from small to big, and the end surface of the intake port of the same, this time the gas is inhaled, when the suction When the end of a small gas chamber and the intake port is cut off, when the impeller continues to rotate, the small chamber from big to small, the gas is compressed, when the small chamber in communication with the exhaust port, the gas becomes 2BV water ring vacuum pump is discharged outside. 2BV water ring vacuum pump by changes in volume of the chamber is to achieve suction, compression and exhaust, so it belongs to the variable displacement pump. 3 Purpose and scope of 2BV water ring vacuum pumps and compressors are widely used in petrochemical, pharmaceutical, food, sugar industry and other fields, mainly used for vacuum filtration, vacuum distillation, vacuum sterilization, extrusion molding, food processing, liquid off gas. 4 Main Features 1, Direct coaxial pump design saves space and is easy to install. 2,2BV water ring vacuum pumps used in all imported mechanical seals as standard. 3,2BV water ring vacuum all with cavitation protection port, such as working under extreme pressure to open the cavitation protection port (or connected to the splitter) eliminates cavitation sound ensure maximum suction effect in the case of , and 2BV water ring vacuum pump protection. 4, high-strength aluminum bronze impeller, durability, and improved 2BV water ring vacuum pump corrosion resistance. As flow components made of stainless steel, it can work in harsher environments. 5, the unique design of flexible vent, without excessive compression, ensuring 2BV water ring vacuum pump efficiency within its optimum performance range. 6, all with Y2 series motor, protection class IP54, IP55 (common to IP44) 7,2BV water ring vacuum pumps used in all NTN or NSK bearings.
