The working principle of precast concrete machinery mainly includes the following aspects:
Hydraulic system drives piston movement: Precast concrete machinery usually uses a hydraulic system to drive the piston to reciprocate in the delivery cylinder. When the piston moves backward, the concrete in the hopper is sucked into the delivery cylinder; when the piston is pushed forward, the concrete is pressed into the delivery pipeline, and the connection between the cylinder and the pipeline is switched through the S valve to achieve continuous pumping.
Molding and curing process: The working principle of cement precast board production equipment is based on the molding and curing process of concrete materials. First, cement, aggregates (such as sand, stone), water and necessary additives are mixed in a certain proportion to form a uniform concrete mixture. Subsequently, the mixture is sent to the molding equipment, and it is compacted and filled into the mold by vibration or pressing to form a precast board of preset shape and size. Finally, after a period of curing, the concrete gradually hardens and reaches the strength required by the design, and it can be demolded and shipped out of the factory.
Automated control: Modern precast concrete machinery usually has a highly automated control system, from batching, mixing, conveying, molding to maintenance, the entire production process can be automatically controlled. This not only improves production efficiency, but also reduces manual intervention, reduces production costs and the possibility of human errors.
Material distribution system: Precast concrete machinery is usually equipped with a material distribution system, such as a retractable/rotatable material distribution boom, which is used to adjust the pouring position. The conveying pipeline is connected to the material distribution boom to ensure that the concrete can be accurately delivered to the pouring position.
Environmental protection and energy saving: Modern precast concrete machinery effectively reduces environmental pollution during the production process by optimizing the production process and adopting advanced dust removal and noise reduction technology. At the same time, efficient energy utilization also reduces production costs, which is in line with the green construction concept of modern buildings.
