SZ - type water ring vacuum pump product overview:
SZ type water ring vacuum pumps and compressors are used to pump or compressed air and other non corrosive, insoluble in water, containing no solid particles, to a certain degree of vacuum in a sealed system, commonly used in vacuum evaporation, vacuum concentration, vacuum drying, vacuum filtration, vacuum feeding process. But the inhaled gas may contain a small amount of liquid which is widely used in mechanical, petrochemical, pharmaceutical, food, sugar and electronic industry. Because in the work process, gas compression is isothermal, so in the compression and pumping flammable, explosive gas, it is not easy to risk, so the SZ type water ring vacuum pump application more widely.
Type SZ has SZ-1, SZ-2, SZ-3 and SZ-4 four kinds of specifications, SZ type water ring vacuum pump formed by the maximum vacuum respectively in the 86~95% between. The maximum pressure of SZ-1 and SZ-2 to form 1.0~1.4 kg / cm 2, SZ-3 and SZ-4 with the maximum pressure in the motor power allowed 1.5 kg / cm 2, if the increase in motor power, the maximum pressure of 2.1 kg / cm 2.
SZ - type water ring vacuum pump model significance:
Description - SZ type water ring vacuum pump structure:
SZ type water ring vacuum pump is composed of pump body (1) and two side cover (2) (3). (Figure 3 and Figure 4) have lower side cover foot pump (a) support (Figure 2), which is in the upper two of the intake pipe and exhaust pipe ((c) F), the two pipe through the suction holes on the side cover (d) and discharge hole (g) connected to the pump chamber communicated with the pump body of the intake pipe and exhaust pipe and the side cover of the suction hole and the exhaust hole, the shaft (4) eccentrically mounted in SZ type water ring vacuum pump in the body, the impeller (6) with the key (5) is fixed on the shaft. The clearance between the impeller and the pump body side cover, and the side cover between the pad to adjust the total clearance, with the sleeve (17) to promote the impeller, so as to adjust the clearance at both ends of the impeller. This gap determines the magnitude of the loss of gas from the inlet to the outlet flow within the pump.

SZ type water ring vacuum pump equipped in the stuffing box cover in both sides of (2) (3), in the back with a filler, water chamber, water from the pipe (11) enter the room, a part of the water cooling through the packing stuffing, the other part into the pump body, under the action of centrifugal force the leaf end flow between the impeller and the full side cover.
A ball bearing (8) is fixed on the shaft by a round nut (9).
In the side cover on the side wall (Figure 2) exhaust hole (g) below a few lines of holes (E) with rubber valve (spherical) closed, these holes have effect was the gas pressure between the blades to exhaust pressure, the exhaust port before the gas discharged automatically, thus reducing power but because of excessive consumption of gas pressure.
Structure diagram of SZ-1 and SZ-2 (Figure 3) shows, with the SZ-3 and SZ-4 structure (Figure 4) the difference is: the inlet and exhaust pipe are respectively in the two side cover, a pipe communicated with the air inlet, a pipe connected with the exhaust port, the pump without valve rubber.
The intake pipe (10) and a gas water separator together supply pump to circulating water, in order to make the pump cavity at both ends of the side gap and get good packing seal, seal tubes (11) must be made by a continuous supply of clean water. At the end of the coupling in order not to make the bearing oil leakage, which is provided with a felt ring (20) to seal.
