Before use, check the working state of the electrical equipment of the concrete delivery pump, whether the instrument works normally, and whether the filter screen and protective device of the hopper work normally. During the transportation of fine aggregate concrete, pay attention to check whether the indication of the pressure gauge is normal. In case of shutdown due to fault, open the slurry release valve to release the pressure and eliminate the fault. Before the pressure reaches zero, do not disassemble the air chamber, pressure valve and pipeline to avoid danger.
The secondary structural column pump is widely used, which also includes some special construction environments, such as the construction of diversion tunnel, culvert, mine tunnel, bridge tunnel and other tunnels, as well as hydraulic engineering, hydropower engineering, slope support, underground construction operation, foundation filling engineering, structural column pouring of large group buildings and so on.
