SZB

SZB Cantilever ring vacuum pump for pumping water, air or insoluble in water, no solid particles, non-corrosive gases up to 85% of the maximum vacuum is especially suitable for use in large-scale water pumps.

This type pump made today are: SZB-4, SZB-8. 4 of them (8) that when the mercury column height of 520 mm of gas (l / s).

SZB pump structure shown in Figure A, the studio by the pump (2), the pump cover (1) form, on the intake and exhaust ports (see Figure III), under the drain screw Cyprus (15) (see figure III), the pump cover with the arrow indicating the direction of rotation, the pump stuffing box and packing gland with (5), built-in filler (4) seal, pump side of the screw holes (16) ( Figure c) consumption of water to supplement water ring.

made from cast iron impeller (3), there are radial distribution l2 blades, a balance hole (for the demolition of two sets of button use) level of axial force. Population ten flat key (9) and shaft (10) sliding connection can adjust the gap along the axial direction. Axis for the high-quality steel, supported on the pump bracket (6) within the two ball bearings (17) on the right end of the flexible coupling (8) and motor directly connected. Bracket (6) with cast iron, with only the port to ensure accurate connection with the pump, the cavity between bearings, lubricating oil can be kept, or yellow with a thin oil slick can be.

from the transmission direction, the shaft is rotated counterclockwise (right exhaust flange for the El, on the left for the inlet flange).
