Model 2BV single-stage water-ring vacuum pump is a single-stage single-acting water-ring vacuum pump.
This type of vacuum pump is a horizontal direct connection type, mainly composed of horizontal motor, impeller, pump body, suction and discharge disc, pump cover, mechanical seal, etc. The vacuum pump part is directly connected with the motor, and the impeller is installed on the motor shaft, so the structure is compact and the installation and maintenance are convenient.
When the impeller rotates, the circulating water of the input pump chamber becomes concentric with the pump chamber and eccentric with the impeller. The water ring divides the impeller into several relatively closed spaces in the circumferential direction. With the rotation of the impeller, the volume of the space will change periodically, with the corresponding cooperation of the fixed suction and exhaust ports. To complete the process of inhalation, compression and exhaust.
1. Use and scope of use
Single-stage water ring vacuum pump is mainly used for pumping, conveying air and other gases, especially for pumping gases containing large amounts of water vapor, and also for pumping gases containing certain corrosiveness. It is the basic equipment for extracting gas from a closed container to obtain vacuum. It can be used alone or as the front pump of the booster pump to form a mechanical booster pump - water ring vacuum pump vacuum unit, which can greatly improve the scope of use of the mechanical booster pump.
This series of vacuum pumps can be applied to vacuum distillation, concentration, drying in chemical and pharmaceutical industries, vacuum dehydration in textile and paper industries, vacuum degassing, forming and pumping in plastic products industries.
