具有工作效率高,占地面积小,较好的自吸能力,经济的维护成本,在污水厂活性污泥处理以及石油石化行业污油处理得到广泛的应用。 Compared with the technical performance of Rohde rotary piston pumps and twin screw pumps, rotary piston pumps have high working efficiency, small footprint, good self-priming capacity, economic maintenance costs, activated sludge treatment in sewage plants, and petroleum and petrochemical industries Sewage oil treatment is widely used.

characteristic Rotary piston pump Twin screw pump
Pump efficiency
65% -90%
≤65%
Self-priming ability
Vertical self-priming 8.7 meters, no need for filling pump
Better self-priming ability
Area
Compact pump design, small footprint, flexible bore diameter
The pump has multiple design structures, but has a large footprint
Conveying direction
The pump is completely symmetrical, allowing forward and reverse rotation and reversible direction
Can not be forward or reverse, reverse conveying is the seal is under pressure
Dry running capacity The mechanical seal is immersed in lubricating oil, does not generate heat, and allows dry running for 30 minutes
Dry running is not allowed, it is easy to burn the pump
Capability
No clogging, the rotor continuously scours the pump, and the sediment has no effect on the pump.
Maximum particulate matter is 0.12mm

的应用上,活性污泥处理的工艺中,由于仅仅是介质与转子的接触,加上有保护衬板的保护,泵的使用寿命要高于双螺杆泵,在更换配件时,整泵无需从管路上拆下,使用工具打开泵壳即可,实现完全在线维护。 In the application of rotary piston pumps , in the process of activated sludge treatment, the service life of the pump is longer than that of twin-screw pumps due to only the contact between the medium and the rotor and the protection of the protective liner. The pump does not need to be removed from the pipeline, and the pump casing can be opened with a tool for complete online maintenance.

Due to the existence of the rotor and the stator of the twin-screw pump, during operation, the friction between the rotor and the stator reduces the service life of the pump. At the same time, the area is large, the maintenance requires more than two people, the time takes 1-2 days, and even the factory returns.

罗德凸轮转子泵与双螺杆泵的生命周期综合使用成本比较20180919

,那么生命周期内的综合使用成本是双螺杆泵的一半。 We have calculated that at the same station, if a rotary piston pump is used , the comprehensive use cost in the life cycle is half that of the twin screw pump.
