Research on Energy - Saving Optimization Strategies for Small Sand Core Machines

Optimizing the power system is a crucial step in energy saving. The motors commonly equipped in small sand core machines can be selected as high - efficiency energy - saving types. These motors adopt advanced electromagnetic designs, which can reduce energy losses and improve the efficiency of converting electrical energy into mechanical energy. At the same time, according to the working characteristics of the sand core machine, the motor power should be reasonably matched to avoid the "big horse pulling a small cart" phenomenon and reduce unnecessary power waste. For example, in some intermittent working links, variable - frequency motors can be used to adjust the rotation speed in real - time according to the working intensity, reducing energy consumption under low - load conditions.

The energy - saving optimization of the heating system is equally important. Many small sand core machines rely on heating to solidify the sand cores. Wrapping the heating components with new insulation materials can effectively reduce heat dissipation. The introduction of an intelligent temperature control system can precisely control the heating temperature. It can start and stop heating at the right time according to the sand core process requirements, preventing energy waste caused by excessively high or low temperatures. For example, when the sand core reaches the curing temperature, the heating power is automatically reduced to maintain a constant temperature, avoiding excessive energy consumption due to continuous high - temperature heating.

Optimizing the work process also contributes to energy saving. Reasonably plan the order of sand core production to reduce equipment idling time. In multi - station small sand core machines, coordinate the work rhythm of each station to keep the equipment running continuously and efficiently instead of frequent starting and stopping. For example, prepare raw materials in advance to ensure smooth feeding of the equipment and reduce waiting time, enabling the sand core machine to produce more qualified sand cores per unit time and relatively reducing the energy consumption per unit product.

Through the upgrade of the power system, heating system, and the optimization of the work process, small sand core machines can significantly reduce energy consumption. This not only saves operating costs for enterprises but also helps the casting industry develop in a green and sustainable direction, achieving good environmental benefits while enhancing economic benefits.
