The mini concrete mixer pump

Mini concrete mixer pump with advanced S-valve reversing, which can satisfy the conveying of concrete, glasses and cutting ring using cemented carbide materials, longer life, high export pressure to meet high-rise buildings and long-distance transport, hydraulic cooling using water-cooled effect, easy to use; , equipped with a manual lubrication system to ensure the transmission service life, electronic control cabinet with cable remote control operation.

Mini concrete mixer pump working principle: pumping concrete is in the role of pump pressure will be deployed in the pipeline transport, cement mortar wrapped coarse aggregate flow to the export, the proposed coarse aggregate priority to use gravel, through the pipeline vertical and horizontal transport, the allocation of good concrete in addition to the strength and stability of ordinary concrete, Also must have the corresponding fluidity and the durability, the mortar content cannot be too low, the maximum aggregate size diameter does not exceed the pumping pipeline diameter one-fourth is advisable. In addition, we should pay attention to control the slump of the concrete, generally according to the height and distance of the pump to determine, the slump on the concrete can be the pump of great impact. If the slump is too large, liquidity is good but easy to produce bleeding and segregation, the slump is too small, the fluidity of the concrete will be affected, resulting in pipe blockage increases the occurrence of plugging accidents.

For the drop, vertical downward pumping construction, the proposed slump should be controlled in 12-16cm for good. It should also be noted that the setting time of concrete is not equal to the setting time of cement, the initial coagulation time is short, will affect the transportation and watering of the concrete mixture, and the final coagulation time is too long, which affects the construction speed of the concrete project. The common factors that influence the initial final coagulation time are concrete admixtures (retarder, early strong component), Mineral admixture (fly ash, mineral powder, etc.) and ambient temperature.
