eps foam building module equipment energy-saving potential_use process of foam machinery

Huasu is very professional in the use of foam machinery. Today, our editor will introduce you to the use of foam machinery. We hope that through our introduction, you will have a deeper understanding of the use of foam machinery and other issues. eps foam building module The production process of the equipment has great energy-saving potential. Taking injection molding machine as an example, the process of injection molding machine is generally divided into several stages such as clamping, injection, melting, holding pressure, cooling, and mold opening. Each stage needs different Pressure and flow rate. For the oil pump motor, the injection molding process is in a changing load state. In the hydraulic system of the fixed pump, the oil pump motor provides a constant flow rate at a constant speed, and the excess hydraulic oil flows back through the overflow valve. This process is called high pressure section. Flow, this backflow will cause energy loss. The use of frequency converters can solve this problem. After adjusting the speed of the oil pump, the oil pump can provide appropriate oil pressure at various stages of injection molding machine production, and reduce energy loss to the greatest extent. Some end users were the first to use frequency converters on eps foam building module equipment. The system integrator provided them with frequency conversion energy-saving transformation schemes for eps foam building module equipment. The effect of the foam is remarkable, and the energy saving potential of eps foam building module equipment is increasing. Many eps foam building module equipment users have used frequency converters to transform their equipment. Welcome to read: A certain amount of foaming agent and water vapor are retained in the beads of the foam machinery and equipment. When they are out of the machine, they will condense into a liquid, and the liquid foaming agent will dissolve into the polystyrene to make the bubbles The pressure drops quickly, negative pressure (partial vacuum) appears in the bubble, and the beads are very soft and easily deformed. Therefore, when air is sent, try not to make the wind pressure too large. The inner wall of the duct should be as smooth as possible, and the bending radius should be as large as possible (to reduce collision resistance). The pipeline should be a good conductor of electricity, and the entire line must be grounded to avoid static electricity. For ignition, the transmission speed should not exceed 8m/s to avoid damage to the beads. A certain amount of foaming agent and water vapor are retained in the pre-expanded beads of the foam machinery and equipment. When they are discharged from the machine, they will condense into a liquid, and the liquid foaming agent will dissolve into the polystyrene to quickly reduce the pressure in the bubbles. , There is negative pressure (partial vacuum) in the bubble, and the beads are very soft and easily deformed. Therefore, when air is sent, try not to make the wind pressure too large. The inner wall of the duct should be as smooth as possible, and the bending radius should be as large as possible (to reduce collision resistance). The pipeline should be a good conductor of electricity, and the entire line must be grounded to avoid eps. The use process of static foam machinery is electric ignition, and the transmission speed should not exceed 8m/s to avoid damage to the beads. The beads just out of the foam mechanical pre-expander are all damp. After being released from the pre-expander, they absorb air and suddenly encounter cold, causing the foaming agent in the honeycomb cells to condense and form a negative pressure in the cells, so the beads are in It must be placed for a period of time after pre-expansion. On the one hand, it is dried, and on the other hand, it is allowed to infiltrate air to eliminate negative pressure, so that the internal pressure and external pressure in the cells are balanced, so as to prevent the cells from collapsing and make the beads elastic. The process of drying, cooling and stabilizing the cell pressure of the EPS beads just out of the pre-expander is called maturation. Maturation improves the further expansion of the pre-expanded beads during the molding process, the fusion between beads and the elasticity of the beads, which is beneficial to improve the quality of EPS products.
