The differences between stationary and mobile concrete batching plant

图片
In the classification of the batching plant, there are stationary concrete batching plant and mobile concrete batching plant . What are the similarities and differences of these two kinds concrete batching plant? In fact, the concept of the two kinds concrete mixing plant is not absolute, it is a relative concept, due to the workplace of commodity concrete mixing plant is fixed, it will not often migrate, so we general use stationary type. Due to the project construction has the duration, at the end of the period, the batching plant will be implemented to migrate to the new construction site, or the equipment should be stored. This requires the engineering station to be designed for the convenience for demolition as the mobile concrete batching plant. During use, the general engineering concrete batching plant product structure design is to minimize the unnecessary parts, taking the equipment base costs and demolition costs into account. Some structural design is overall hauling or ba...

The advantages of mobile concrete batching plant

How to use the trailer pump concrete correctly

图片
Many friends may know that the trailer pump concrete is used for pumping concrete effectively. But do you know to to use it correctly? Do you know how to dear with the fault while working? If you do not know, I am so pleased to tell you about it. Before pumping concrete, pumping water for lubricate the pipeline, check whether the pipe is sealed, whether there is water leakage, and then pumping mortar through the pipeline. After ensure the mortar has open the pipeline, stirred the remaining concrete fully and then pump normally. When start or stop pumping concrete, should contact with the front-end operator in order to avoid accidents. During pumping process, the concrete should be guaranteed above the mixing axis, empty suction or empty pumping is not allowed. The operator should pay attention to hydraulic oil temperature, rise to 50C should start air-cool for heat dissipation, if the oil temperature continues rising to more than 80C, the operator should stop the machine to do inspec...

Operation rules of the trailer concrete pump outrigger

The main components of trailer concrete pump are the engine and the oil pump. The engine used in trailer concrete pump is diesel engine or electric motor, which is the power source of the pump. The engine power and the main oil pump must be matched reasonable, which increase the equipment efficiency most. Based on this principle, the computer simulation design calculation in constant power, the system pressure and the pump displacement curve is the most reasonable. The current mainstream diesel pump is the German DEUTZ pump pressure blocking type water cooled diesel engine. The engine has the advantages of strong power, low fuel consumption, low noise and low emission. The motor chooses the domestic famous brand motor, its protection level reaches IP54 level, and the noise is small, the efficiency is high, the torque is high, the starting performance is good. The main oil pump is an axial piston variable pump, the output flow and driving speed and pump displacement is proportional, a...

Selection principles of concrete batching plant
