1, WZ type horizontal self-priming pump for single-stage, single-suction, horizontal centrifugal pumps, its size accord with ISO2858 standard;
2, WZ type horizontal self-priming pump adopts the advanced Japanese forced gas liquid separation technology design;
3, WZ type horizontal self-priming pump has a wide range of performance, efficiency and cavitation performance, self-priming performance indexes, such as more than other types of self-priming pump in China
Second, the CWZ horizontal self-priming pump structure characteristics
1, CWZ type horizontal self-priming pump has simple structure, is not easy to malfunction, maintenance is convenient;
Type 2, CWZ horizontal self-priming pump doesn't need bottom valve, vacuum pump, gas separator and other auxiliary equipment. In addition to the first start need filler, repeated start no longer need to pour, operation more convenient;
3, CWZ type horizontal self-priming pump recovery capability, allowing medium mixed with gas, strong self-priming capacity;
4, CWZ type horizontal self-priming pump running curve flat, high efficiency and cavitation is not easy to happen.
Third, CWZ horizontal self-priming pump self-priming principle
CWZ type horizontal self-priming pump start, there is a certain amount of liquid in the pump body, pump starts, due to the impeller rotation, in under the action of centrifugal force, the liquid out of the pump body, through the liquid cavity recycle back down at the inlet of the impeller. Gradually in the process of liquid cycle, to bring the air suction pipe circulation flow, the formation of gas liquid mixture, pour the mixture by impeller conveying pump body of the gas-liquid separation indoor separation, gas is removed from the overflow, the liquid is returned impeller inlet recirculation, which continuously, until the air pump suction tube work done so far.
