I. Introduction to 2BV Water Ring Vacuum Pumps
The SKA/2BV water ring vacuum pumps are suitable for extracting gas and water vapor, with an intake pressure reaching 33 mbar absolute (97% vacuum degree). When the vacuum pump operates for a long time at an intake pressure below 80 mbar, a cavitation protection pipe should be connected to protect the pump. When equipped with a gas ballast, the intake pressure can reach 10 mbar, and it can be directly installed on the vacuum pump. When used as a compressor, its maximum pressure is 0.26 MPa (absolute pressure). It can be widely used in petrochemical, pharmaceutical, food, sugar manufacturing and other industries. Since the compression process of gas is isothermal during operation, there is no danger when compressing and extracting flammable and explosive gases, making its application more extensive. With its excellent performance and numerous advantages, it will fully replace the SK and 2SK series water ring vacuum pumps, as well as the W, WY, and WL series reciprocating vacuum pumps with the same performance.
II. Structure of 2BV Water Ring Vacuum Pumps
The SKA/2BV water ring vacuum pump consists of components such as a pump cover, pump body, disc, impeller, mechanical seal, and motor. The intake and exhaust pipes are connected to the pump chamber through the intake and exhaust holes on the disc installed on the pump cover. The shaft is eccentrically installed in the pump body, and the impeller is fixed on the shaft with a flat key. The total clearance between the two end faces of the pump is adjusted by the gasket between the pump body and the disc, and the clearance between the impeller and the disc on the pump cover is adjusted by the gasket between the disc and the pump body. The clearance between the two end faces of the impeller and the disc on the pump cover determines the loss of gas flowing from the intake port to the exhaust port in the pump chamber and its ultimate pressure. The seal adopts a mechanical seal, which is installed between the impeller and the pump body. The mechanical seal determines the clearance between the impeller and the pump body. A disc is installed on the pump cover, and the disc is provided with intake and exhaust holes and a flexible gas exhaust valve plate. The function of the flexible valve plate is to discharge the gas before the exhaust port when the gas pressure between the impeller blades reaches the exhaust pressure, reducing the power consumed due to excessive gas pressure and thus lowering power consumption.
III. Detailed Features of 2BV Water Ring Vacuum Pumps
The pump adopts a coaxial direct-coupled design, saving space and being easy to install.
It is equipped with a mechanical seal as standard, eliminating leakage and simplifying maintenance. It operates smoothly with low noise.
With a unified corrosion-resistant design, the bronze impeller improves the pump's corrosion resistance, and the stainless steel material is more suitable for harsher applications.
The unique flexible exhaust port design avoids over-compression, ensuring the working efficiency of the SKA within its performance range.
