Water ring pumps can be divided into the following types according to different structures.
Type |
Characteristic |
| Single stage single acting water ring pump | Single stage means that there is only one impeller, and single action means that the suction and exhaust are carried out once every rotation of the impeller. The extreme vacuum of this pump is high, but the pumping speed and efficiency are low. |
| Single stage double acting water ring pump | Single stage means that there is only one impeller, and double action means that the suction and exhaust are carried out twice for each rotation of the impeller. Under the same pumping speed, the size and weight of double acting water ring pump are greatly reduced than that of single acting water ring pump. Since the working chamber is symmetrically distributed on both sides of the pump hub, the load acting on the rotor is improved. This kind of pump has high pumping speed and efficiency, but the limit vacuum is low. |
Two stage water ring pump |
Two stage water ring pumps are mostly single acting pumps in series. In essence, the impellers of two single-stage single acting water ring pumps are connected by sharing a mandrel. Its main feature is that it still has large pumping speed under high vacuum and its working condition is stable |
Atmospheric water ring pump |
Atmospheric water ring pump is actually a unit of atmospheric ejector series water ring pump. The atmospheric pump in series in front of the water ring pump is to improve the limit vacuum and expand the application range of the pump |

With the development from acid papermaking to neutral papermaking, the scaling of papermaking water ring vacuum pump is a problem often encountered by every papermaking enterprise, whether in the South or the north. Scaling is a process, which is not generated at once. With the generation of scaling substances, its impact on the paper machine is gradually emerging. Therefore, we should not take it lightly. We should persevere and prevent scaling from the beginning, which will produce long-term benefits.
1. Scaling causes:
(1) High pH value and high hardness.
(2) The sealing degree of papermaking white water increases, the content of insoluble matter is high, and the scaling ion accumulates.
(3) Extensive use of fillers.
(4) Temperature. The water temperature rises and the cooling system does not work well.
2. Adverse effects on papermaking:
(1) Seriously reduce the vacuum degree and air extraction.
(2) The motor current increases, resulting in increased power consumption.
(3) It often causes the problems that the vacuum pump is stuck, it is difficult to start, the paper machine stops and the vacuum pump dare not stop.
(4) Frequent pickling or manual disassembly will not only damage the equipment, but also damage the equipment accuracy, resulting in the failure of vacuum formation or the reduction of vacuum degree.
3.solve:
(1)The hardness of water must be reduced as much as possible and the working temperature of circulating water must be controlled. During the operation of circulating cooling water, the return water temperature and return water volume of each pump shall be tested to ensure that the normal water supply and return water temperature of each pump do not exceed 40 ºC
(2) The pump body drainage valve of the water ring vacuum pump is not only used to normally discharge the accumulated water in the pump, but also can regularly flush the dirt and water in the pump by using the water pressure of the pump body during operation. On the one hand, it can prevent the accumulation of dirt and on the other hand, it can also prevent the conversion of water slag into scale.
