Working Principle:
The doing work theory of the 2SK water ring vacuum pump is shown in Figure 1. The impeller (5) is eccentrically set up in the pump physique (3). When the impeller rotates, the h2o is thrown all around by the centrifugal power. A rotating water ring (6) is fashioned amongst the impellers. The interior area of the upper portion of the water ring is in contact with the impeller hub. When the impeller rotates clockwise, in the procedure of the first half rotation, the interior surface area of the h2o ring progressively separates from the hub, and the cavity formed between the adjacent two blades gradually boosts. , the pumped fuel passes through the pump inlet pipe (4), and is repeatedly sucked into the cavity via the crescent-formed suction gap (7) in the course of the CZPT 50 percent-change, the interior surface area of the h2o ring steadily ways the hub, and the area among the two adjacent blades The cavity is progressively decreased and the fuel is compressed, so the force is constantly improved. When the strain is enhanced to be better than the exterior strain, the gas is discharged, so that the gas in the sealed container is repeatedly drawn absent to kind a certain vacuum.

The atmospheric jet vacuum pump is a jet pump, and its working principle is briefly described as follows: Owing to the motion of the 2SK drinking water ring vacuum pump, the pumped container types a specific pre-vacuum. When it is close to the greatest vacuum of the pump, the atmospheric pump is turned on. At this time, The pressure distinction between the exterior environment (or pressurized fuel) and the ingestion pipe is very huge. Underneath the action of this pressure distinction, the atmosphere (or fuel) is rapidly drawn into the suction pipe. After passing by way of the nozzle of the atmospheric pump, the airflow speed is additional improved, so The force drops speedily so that a comparatively large vacuum (apparently larger than the pump’s ultimate vacuum) is designed in the nozzle, which carries on to attract the gasoline getting pumped into the pump.

The structure of the 2SK h2o ring vacuum pump with an air extraction potential of 1.5m3/min or much more is shown in Determine 2. The CZPT and brief impellers 17 and sixteen are mounted on the shaft 2 with keys, the middle of the two impellers is positioned with a shaft sleeve twenty, and locked with a garden nut. It constitutes the whole rotor element, and is eccentrically set up in the pump 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 velocity with the motor, and it is CZPT . The impeller 17, the CZPT pump human body 9 and the suction portion sort a substantial vacuum phase, the brief pump entire body 5, the short impeller 16 and the discharge portion form a reduced vacuum phase, and the exhaust port of the high vacuum phase and the suction port of the low vacuum phase are related by a connecting pipe ( 2SK-1.5 with out this connecting pipe) gets a two-stage series, the two stages are divided 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.
Determine 3 Composition diagram of 2SK-.4, 2SK-.8 two-stage drinking water ring vacuum pump
The composition of 2SK-.4, 2SK-.8 two-stage h2o ring vacuum pump is revealed in Determine 3, and its higher and lower vacuum phase composition is basically the very same as that of the pump proven in Determine 2 (no connecting pipe). Employing a unique extended shaft motor, the CZPT and brief impellers are mounted on the shaft with keys, but they can be floated axially and eccentrically put in the CZPT and short pump bodies.
The seals at equally ends of the 2SK water ring vacuum pump use oil-impregnated asbestos packing or mechanical seals.
One particular finish of the large vacuum stage has a drinking water inlet hole, from which the supplementary drinking water enters the CZPT pump physique of the large vacuum stage, and the supplementary drinking water of the minimal vacuum stage is discharged from the large vacuum phase. (2SK-twelve, 2SK-twenty, 2SK-30 low vacuum amount make-up drinking water is also equipped from the h2o offer pipe, but the amount should be adjusted through the valve). The substantial and lower vacuum stages are firmly connected with each other by stress bolts.
