A water ring vacuum pump (referred to as water ring pump) is a type of rough vacuum pump. The ultimate vacuum it can achieve is 2000~4000Pa, and with a series-connected air ejector, it can reach 270~670Pa. Water ring pumps can also be used as compressors, known as water ring compressors, which are low-pressure compressors with a pressure range of 1~2×10Pa gauge pressure. Water ring pumps were initially used as self-priming water pumps, and later gradually used in many industrial sectors such as petroleum, chemical, machinery, mining, light industry, medicine, and food. In many industrial processes, such as vacuum filtration, vacuum priming, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum conditioning, and vacuum degassing, water ring pumps are widely used. Due to the rapid development of vacuum application technology, water ring pumps have always been valued for obtaining rough vacuum. Since the gas compression in a water ring pump is isothermal, it can extract flammable and explosive gases, and also gases containing dust and water. Therefore, the application of water ring pumps is increasing.
Product Introduction
The working liquid of a water ring vacuum pump can also be other suitable liquids. Regardless of the working liquid used, it is collectively referred to as a liquid ring vacuum pump. The water ring vacuum pump is the most common and widely used type of liquid ring vacuum pump.
Application Scope
Application Scope of 2BV Series Water Ring Vacuum Pumps
■ Structure and Features
The 2BV series vacuum pump is suitable for extracting gases and water vapor, with suction pressure reaching 33mbar absolute pressure (97% vacuum). When the vacuum pump operates for a long time at suction pressure below 80mbar, a cavitation protection pipe should be connected to protect the pump. If equipped with an atmospheric ejector, the suction pressure can reach 10mbar. The ejector can be directly installed on the vacuum pump. When used as a compressor, the maximum pressure is 0.26MPa (absolute pressure).
Water ring vacuum pumps and compressors are widely used in petrochemical, pharmaceutical, food, sugar, and other industries. Since the gas compression process is isothermal during operation, it is less prone to danger when compressing and extracting flammable and explosive gases, making its application more extensive.
△ Coaxial direct-coupled design of pump and motor saves space and is easy to install.
△ Mechanical seal is used as standard configuration, eliminating leakage and simplifying maintenance.
△ Stable operation, noise can be as low as 62 decibels.
△ Unified corrosion-resistant design, bronze impeller enhances corrosion resistance, stainless steel material is more suitable for more demanding applications.
△ Unique flexible exhaust port design prevents over-compression, ensuring optimal efficiency of 2BV within its performance range.
II. Application Scope of 2BE Series Water Ring Vacuum Pumps
■ Structure and Features
The 2BE series water ring vacuum pump and compressor is a new high-efficiency and energy-saving product developed by our company based on long-term scientific research, combined with international advanced technology, and continuously verified through practice. It is commonly used to extract gases that do not contain solid particles, are insoluble in water, and are non-corrosive, in order to form vacuum and pressure in sealed containers. By changing the structural materials, it can also be used to extract corrosive gases and corrosive liquids. It can be widely used in papermaking, chemical, petrochemical, light industry, pharmaceutical, food, metallurgy, building materials, electrical appliances, coal mining, ore dressing, fertilizer, and other industries.
The 2BE series water ring vacuum pump adopts a single-stage single-acting structure, with advantages such as simple structure, convenient maintenance, high efficiency and energy saving, and reliable operation. The key components such as pump shaft, impeller, and distribution plate have been optimized in design. Whether it is a ductile iron impeller or a stamped welded impeller, it undergoes proper heat treatment and is balanced and dynamically balanced before and after interference hot assembly, resulting in smoother operation and better impact resistance, suitable for harsh working conditions with large displacement and load impact fluctuations.
The 2BE series water ring vacuum pump comes with a built-in gas-water separator; it has multiple inlet and exhaust port positions, and an exhaust valve inspection cover window is added on the pump cover, making assembly and maintenance more convenient.
