Sewage Rotary Lobe Pump are used for conveying activated sludge, dosing, sludge reflux, centrifuge belt machine feeding, etc., and are used to replace the screw pumps used in traditional processes. The working principle of the pump is to use the change of the pump cavity volume to realize the continuous conveying of the medium, with super self-priming force, can be positive and negative rotation, high conveying efficiency, low maintenance cost.

After the sludge is thickened and treated, the general water content is about 95%-97%. Detach the void water in the sludge, the content water rate is 75% - 80%, the adsorbed water and capillary water in the sludge is separated out, the volume of sludge after dewatering is greatly reduced, not only to reduce the secondary pollution of the environment, but also for the sludge transportation, disposal and comprehensive utilization of the sludge to create a more favorable conditions. After the screw propeller into the Rotary Lobe Pump pump body, Rotary Lobe Pump to 45 - 60 rpm speed extrusion, efficient and smooth transportation to the storage tank or directly loaded.

With the rapid development of rail transportation engineering construction, people's requirements for the environment of the subway station are increasing. The traditional drainage method of installing submersible pumps in the catchment basin of the subway station to lift the sewage has a series of drawbacks, such as inconvenient maintenance, odor, easy to breed bacteria, etc. So there is an urgent need for a new type of sewage technology. Vacuum drainage system as an optimized sewage system, energy saving and operation and maintenance, especially in the improvement of the environment has very obvious advantages, can effectively solve the traditional underground sewage discharge method of the whole disease.

The ground unloading system of railroad station section and subway sewage suction system produced by our company have reached the international advanced level in terms of R&D technology, manufacturing technology and application technology. The main function of high-speed railroad unloading system is on-board sweeping warehouse, moving car sewage, vacuum sewage system, a sewage tank only needs 1 minute and 20 seconds to complete the operation, a high-speed railroad 16 sections, two workers cross operation in about 15 minutes to unload the sewage to complete, high efficiency and quick. The maximum suction power reaches vacuum-80KPa, with self-control system to automatically replenish the vacuum, simple and convenient operation, it can prevent hard particles from entering the pump body, which effectively meets the requirements of high-speed rail station section for fast and environmental protection.
