Compulsory mixer mixing capability introduced
In short mixing time is generally compulsory concrete mixer stirring power four 3.4.5.7 minute abnormal compulsory mixer and stirred needle stirred RPC, proposed mixing time stirring, stirring speed of 9 seconds, the effect of the energy consumption test flash, stirring time extended whereabouts. Curve shows that stirring longer concrete activities to improve qualities. Compulsory mixer stirring prolonged Students can improve the small concrete pump concrete mixer balance of the situation to extend the mixing time to move forward, then mixing concrete mixing station, stirring stretch of time, in order to improve the usefulness of specific activities fresh concrete situation. Each extension activities to reduce functional improvement, therefore, function and stability. Superplasticizer mixed guess, in a specific activity, there is a significant test results showed: Participation concrete water reducer is very important to separate time lead to changes in fresh water reducer participation features huge concrete UHPC differences. Initially, about two-thirds of the mixed water will exceed the direct participation, appropriate to defer the total amount involved in the mixer of the remaining portion of the plasticizer.
The first and second time intervals between longer want to participate, and more specifically the positive steep compulsory mixer features fresh concrete mixing speed, mixing time with higher mandatory testing during the same period stirring speed mixer fresh UHPC specific functions can be a greater degree of locking. Forward by stirring intensity active functional improvement degree of certainty, then it does not detect further improvements. Therefore, when the mixing blade forced mixer at a higher speed, the task of reducing the stirring time is certainly possible.
Concrete mixing station pumps Introduction
For a commercial concrete mixing station, complete configuration determines its efficiency and quality problems in the build process. So, let’s look at the main commercial concrete mixing station configuration and the concrete mixing pump works station.
Commodity concrete mixing station mixing machine: twin-shaft compulsory concrete mixer, electric drum, drum concrete mixers, pneumatic valve, a stepped concrete mixer, concrete batching machine, cement soil, cement tank, screw conveyor, Diesel concrete pump manufacturers concrete placing boom, belt conveyor, and water weighing, weighing cement, concrete mixing station computer control system, and recovering dust, dust and broken arch, weighing hopper, a vibration sensor, stirred tank. In addition to essential equipment, concrete mixing station, concrete pump is essential. Concrete pump is the use of pressure along the pipeline will be concrete continuous conveyor. It is composed of a pump and pipes. Into concrete feeding piston pump, pressure membrane structure. Concrete pumps concrete mixing station, concrete pump hydraulic and mechanical drive. Concrete pump hydraulic drive by a bucket cylinder and piston, concrete cylinder, valve, γ- pipes, washing equipment, hydraulic systems and electrical system components. Hydraulic system pushes the piston reciprocates, pressure. When the piston moves back to the suction, when pushed through the pipe cylinder concrete pipe concrete y. After completion, with high pressure water or compressed air to clean the pump and piping concrete pumps. Displacement piston pump concrete depends on the number and diameter concrete cylinder, speed reciprocating motion of the piston and the concrete cylinder intake volumetric efficiency. Understanding the pump works after concrete mixing station, when it fails, when the fault can troubleshoot and repair according uh works.
