Working Principle:
The operating theory of the 2SK drinking water ring vacuum pump is demonstrated in Figure 1. The impeller (5) is eccentrically put in in the pump physique (3). When the impeller rotates, the h2o is thrown about by the centrifugal drive. A rotating water ring (6) is formed in between the impellers. The interior area of the upper part of the h2o ring is in get in touch with with the impeller hub. When the impeller rotates clockwise, in the procedure of the 1st 50 percent rotation, the inner area of the h2o ring gradually separates from the hub, and the cavity fashioned between the adjacent two blades steadily raises. , the pumped gas passes via the pump inlet pipe (4), and is continually sucked into the cavity by way of the crescent-shaped suction hole (7) throughout the CZPT fifty percent-turn, the inner area of the drinking water ring progressively methods the hub, and the area in between the two adjacent blades The cavity is progressively reduced and the gas is compressed, so the stress is continuously improved. When the strain is increased to be better than the exterior stress, the gas is discharged, so that the gas in the sealed container is repeatedly drawn away to form a specified vacuum.

The atmospheric jet vacuum pump is a jet pump, and its doing work principle is briefly described as follows: Because of to the action of the 2SK h2o ring vacuum pump, the pumped container types a particular pre-vacuum. When it is close to the ultimate vacuum of the pump, the atmospheric pump is turned on. At this time, The force big difference amongst the outside ambiance (or pressurized gasoline) and the consumption pipe is very huge. Below the motion of this stress big difference, the atmosphere (or gas) is speedily drawn into the suction pipe. Soon after passing via the nozzle of the atmospheric pump, the airflow velocity is further elevated, so The force drops rapidly so that a relatively large vacuum (evidently higher than the pump’s supreme vacuum) is designed in the nozzle, which carries on to attract the gasoline currently being pumped into the pump.

Figure two Structural diagram of two-stage water ring pump with air pumping potential earlier mentioned 1.5m3/min (2SK-1.5)
The structure of the 2SK drinking water ring vacuum pump with an air extraction capacity of 1.5m3/min or more is revealed in Determine 2. The CZPT and short impellers seventeen and sixteen are fastened on the shaft 2 with keys, the center of the two impellers is positioned with a shaft sleeve 20, and locked with a garden nut. It constitutes the total rotor part, and is eccentrically set up in the pump human body, supported on two single-row radial ball bearings, and the rotor element is connected with the motor shaft by a coupling 18, so that it rotates at the exact same speed with the motor, and it is CZPT . The impeller seventeen, the CZPT pump entire body 9 and the suction element sort a high vacuum stage, the short pump human body 5, the brief impeller 16 and the discharge portion kind a low vacuum phase, and the exhaust port of the high vacuum phase and the suction port of the lower vacuum phase are linked by a connecting pipe ( 2SK-1.5 without this connecting pipe) becomes a two-stage series, the two phases are separated by an intermediate wall (A) 7 and an intermediate wall (B) 6, there are exhaust holes on the intermediate wall (A), and the intermediate wall (B) There is a suction port on the prime.
Figure 3 Composition diagram of 2SK-.4, 2SK-.8 two-phase h2o ring vacuum pump
The construction of 2SK-.4, 2SK-.8 two-stage h2o ring vacuum pump is shown in Figure 3, and its substantial and minimal vacuum stage structure is basically the very same as that of the pump proven in Figure 2 (no connecting pipe). Employing a particular extended shaft motor, the CZPT and short impellers are set on the shaft with keys, but they can be floated axially and eccentrically positioned in the CZPT and quick pump bodies.
The seals at both ends of the 2SK h2o ring vacuum pump use oil-impregnated asbestos packing or mechanical seals.
One conclude of the substantial vacuum phase has a drinking water inlet hole, from which the supplementary h2o enters the CZPT pump physique of the higher vacuum phase, and the supplementary drinking water of the reduced vacuum stage is discharged from the substantial vacuum phase. (2SK-twelve, 2SK-20, 2SK-thirty reduced vacuum level make-up drinking water is also supplied from the drinking water supply pipe, but the amount ought to be modified by way of the valve). The substantial and lower vacuum stages are firmly connected with each other by pressure bolts.
