2BV water ring vacuum pump Purpose and scope:
2BV series water ring vacuum pump for the overall structure – coaxial pump single stage pump. Seal mechanical seals, has a simple structure, simple installation, oil-free, safe and reliable. 2BV series water ring vacuum pump is suitable for pumping gas and wet steam, suction pressure can reach 33mbar absolute pressure (97% vacuum), while long-term 2BV water ring vacuum pumps work under suction pressure below 80mbar state should join cavitation protection to protect the pump, 2BV water ring vacuum pumps such as with air jet suction pressure up to 10mbar, injector pump can be mounted directly on the intake port, when used as a vacuum compressor, the pressure up to 0.26MPa (absolute pressure).
2BV series water ring vacuum pumps and compressors are widely used in petroleum, chemical, pharmaceutical, food, sugar industry and other fields. As in the work process, the gas compression process is isothermal, so the compression and pumping explosive gas, less prone to explosion, so its wider application.
2BV water ring vacuum pump works:
2BV water ring vacuum pump impeller eccentrically mounted in the pump body, starting to pump water into a certain height, so that when the impeller 3 rotates, centrifugal force by the water in the pump body wall to form a rotating water ring, in the lower part of the water surface and the hub ring tangent rotation direction of the arrow, turn the course of the first half, within 2BV water ring vacuum pumps water ring surface gradually from the hub, so the ring between the impeller blades with water to form a closed space, with rotation of the impeller, the space gradually expanded, gas space pressure is reduced, the gas is sucked into the suction port from the disk; spinning up process in the second half, the surface becomes increasingly close to the hub within the water ring, the space between the blades is gradually reduced, the gas pressure space elevated pressure higher than the exhaust port, the gas between the blades of the exhaust port is discharged from the disk. So every one rotation of the impeller, the space between the blades of the suction and discharge time, a lot of space to work non-stop, 2BV water ring vacuum pump on continuous suction or pressure feed gas.
2BV water ring vacuum pump because of the work process, acting to generate heat, water loop heat would work, but part of the water and the gas is discharged together, therefore, in the course of their work, we must continue to give pump water to cool and add consumption of water in the pump, the pump to meet the job requirements.
When 2BV water ring vacuum pump exhaust gas is no longer utilized, the 2BV water ring vacuum pump exhaust port is connected with the gas-water separator, gas and brought back some of the water into the gas-water separator, gas and water separation, gas from the exhaust pipe, leaving the water supply through the return pipe to continue to use the pump. With the extension of working hours, work the water temperature will continue to rise, then the need for water supply from the water supply pipe to reduce the working temperature of the water to ensure that the technical requirements and performance indicators to achieve the required
