Abstract

The present invention relates to a rubber injection moulding machine energy-saving control system. It includes frequency converter drive motor, liquid pressure and flow rate sensor, temperature sensor and power supply circuit. Its energy-saving control system is formed from monitoring controller, technological process control module, temperature sampling and control module and frequency converter drive control module. Said invention also provides the working principle and operation method of said system.

Description

technical field [0001] The invention relates to a frequency conversion energy-saving control system, in particular to a frequency conversion energy-saving control technology for a drive motor of a rubber injection molding machine, which realizes group centralized control and remote energy-saving supervision while controlling the process flow of the rubber injection molding machine. Background technique [0002] Due to changes in the working environment of various driving motors, their loads also change accordingly. Therefore, the energy waste caused by the difference between the fixed power output and the actual load has become one of the current energy-saving research directions for driving motors. In the hydraulic system of rubber injection molding machine, the principle of pump selection is generally based on the maximum flow of the system plus a certain margin. In the actual production process, the driving motor always drives the hydraulic pump at a stable speed to outpu...
