Water ring cantilever vacuum pump

1SZB water ring cantilever vacuum pumpUsage characteristics and pictures:

The SZB cantilever water ring vacuum pump is suitable for suctioning air or water-insoluble, solid particle free, and non corrosive gases, with a vacuum degree of up to 85%. It is particularly suitable for large water pump water intake. The currently manufactured pumps of this model include SZB-4 and SZB-8. Among them, 4 (8) represents the gas volume (liters/second) when the mercury column height is 520 millimeters.
The SZB series water ring suspended wall vacuum pump is a water ring vacuum pump that adopts a suspended wall structure. Can be used for suctioning air or other non corrosive, water-insoluble, and solid particle free gases. The suction pressure of the water ring cantilever vacuum pump is -0.086MPa. The SZB series water ring suspended wall vacuum pump is widely used for conveying various media in industries such as machinery, petroleum, chemical, pharmaceutical, food, and other fields. Especially suitable for large water pump water intake.

IISZB water ring cantilever vacuum pumpStructural description
The structure of SZB water ring cantilever vacuum pump is shown in Figure 1. The working chamber consists of a pump body (2) and a pump cover (1). There are inlet and outlet ports on the upper part (see Figure 3), and a drain plug (15) on the lower part (see Figure 3). The pump cover has an arrow indicating the direction of rotation. The pump body has a packing box and a packing cover (5), and is sealed with packing (4). The screw hole (16) on the side of the pump body (see Figure 3) is used to supplement the water consumption of the water ring.
The impeller (3) is made of cast iron, with 12 blades distributed radially and balanced with holes (two of which are for disassembly) to balance axial forces. The leaf wheel flat key (9) is connected to the shaft (10) and can slide along the axial direction to adjust the clearance. The shaft is made of high-quality steel and is supported by two ball bearings (17) inside the pump bracket (6). The right end of the bearings is connected to an elastic coupling (8) and the motor directly. The bracket (6) is made of cast iron and has a stopper to ensure accurate connection with the pump body. There is a cavity between the bearings that can store lubricating oil, which can be used with thin oil or butter.
