There are many weeds in the water intake of the pump station, and the water intake conditions are poor. The trash rack is often blocked by weeds, causing cavitation and a decrease in efficiency of the unit. When the pump station is started to fight drought, the trash rack is often blocked seriously, especially in the rainstorm weather, the fast confluence flood will flush the dead branches, sundries, water plants, etc. to the pump station inlet, which can cause serious shutdown accidents. Therefore, selecting small cleaning equipment with simple structure, easy operation and maintenance, and high automation level has become an important measure for the normal operation of pump stations.
Currently, there is a disparity in the research level of cleaning machines both domestically and internationally. Foreign countries are leading domestic enterprises in technology development and manufacturing, especially in large-scale cleaning machinery and equipment, which is still a blank in China. The research and development of foreign cleaning machines have been moving towards intelligence and automation, while domestic cleaning machines have also developed rapidly in recent years. New types of cleaning machines such as cyclic, rotary, grab bucket, rotary, rotary brush mesh, grid, and suspension have been developed, with relatively complete specifications, a wide variety, and advanced technology. They are mainly used in hydropower stations and pump stations, and are also widely used in the pre-treatment of sewage in urban and planned communities, as well as the treatment of imported debris in water plants, sewage treatment plants, power plants, steel mills, etc.
The use of hydraulic grab bucket cleaning machine in pump station
To solve the problem of incomplete and unclean cleaning, the new hydraulic grab bucket cleaning machine selected adopts a reverse hook shaped grabbing tooth, and the cleaning grab bucket reliably meshes with the grid tooth groove, effectively removing the dirt on the grid surface. Improving the locking device of the grab bucket effectively prevents dirt from falling off during the lifting process. And according to the water intake conditions of different pumping stations and the types of pollutants, different structural forms of grab buckets are selected. Whether it is floating aquatic plants, domestic garbage, or semi floating or sinking debris, they can be easily and flexibly grasped clean, and the cleaning effect is very ideal.
The new hydraulic grab cleaning machine adopts advanced remote control and hydraulic control technology, making the overall structure simple and easy to operate and maintain. And further improve the host overload, limit, and fault alarm protection system, using a PLC programmable controller to achieve automatic control of the entire process of cleaning machine walking, grab lifting, cleaning, and unloading. Improve the automation level of the cleaning machine to meet the needs of different working environments.
