1、 Product shooting

  2、 The purpose and significance of filling industrial pumps
Industrial filling pump can be used for filling coal mine goaf, non coal mine goaf, red mud transportation, coal slurry transportation, sludge transportation, as well as the transportation of high concentration paste and slurry in metallurgy, chemical, and petroleum industries. It has the characteristics of high concentration of transportable medium, long conveying distance, large conveying volume, and stable and reliable equipment operation.
Industrial filling pumps can transport various media including mine tailings paste, coal gangue gypsum, fly ash paste, as well as power plant coal slurry, aluminum plant red mud, underwater sludge, etc. As long as it has a certain concentration and solid particles can be stably suspended in the mixture, both paste and slurry media can be transported.
The filling industrial pump is used for filling in goaf areas such as mines, which can effectively solve the phenomenon of surface collapse caused by goaf, effectively avoid accidents such as underground water permeability and gas outburst, and is very beneficial for safety production. At the same time, after filling, mining operations can also be carried out in the mining area. For example, coal mines can use the goaf filling process to achieve "three down" coal mining, which can reduce the waste of valuable ore resources. In addition, as the filling materials are mostly waste generated during the mining process, such as tailings sand, coal gangue, fly ash, etc., these waste materials accumulate on the ground for a long time, not only occupying land, but also polluting water sources and air. If they can be filled underground, the environmental damage caused by the accumulation of ground waste can be completely solved.
Industrial filling pump can be used for mining tailings filling and tailings dry discharge transportation, as well as for the transportation of high concentration mud, slurry, chemical sludge and other materials The Heyu filling industrial pump has the characteristics of high conveying pressure, stable and reliable quality. All hydraulic and electrical components are selected from high-quality brands, and the control method is Heyu's patented technology - dual pump dual circuit hydraulic control reversing control system, which can work continuously for 24 hours without interruption. It has been successfully applied in multiple mines.
Therefore, the application of filling industrial pumps is of great significance for achieving green, environmentally friendly, safe, and sustainable production in mines.
