Description
Technical field
The utility model relates to the control device technical field, specifically belongs to a kind of energy conservation apparatus of plastic jetting-moulding machine.
Background technology
Complete production process of fluid pressure type injection machine comprises locked mode, injection, pressurize, cooling, the die sinking stage, its each operation during operation, be used for driving the drive motors that the pressure source oil pump is provided and be in the work running always, and each operation of injection machine exists different because of the demand to pressure, so the actual power demand of oil pump changes greatly, as in injection, pressurize and cooling stage, equipment is very low to the motor utilization rate of used oil pump, still keep running to keep power output to immobilize and drive the motor of oil pump this moment, produce superfluous hydraulic pressure and can only lean on the overflow valve of oil pump to regulate, so just have the electric energy of considerable part to be wasted by overflow valve.
The utility model content
The purpose of this utility model provides a kind of energy conservation apparatus of plastic jetting-moulding machine, and the electric energy loss when effectively reducing injection machine work also improves the injection machine utilization rate of electrical, and project organization is reasonable, and operation is stable.
The technical solution adopted in the utility model is as follows:
A kind of energy conservation apparatus of plastic jetting-moulding machine, comprise servomotor, hydraulic pump, servo electric-control system, hydraulic cylinder, pressure control device, described hydraulic cylinder is connected by pipeline with hydraulic pump, be provided with accumulator between hydraulic pump and the hydraulic cylinder, be provided with pressure valve between accumulator and the hydraulic pump, described pressure control device input is communicated with accumulator, and output is connected in the high-pressure pump motor, and hydraulic pump and servomotor are in transmission connection.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The utility model adopts the high-pressure pump motor to make normally open, the oil-out of two driven by servomotor pumps is connected to the system high pressure pipe jointly, oil return pipe is connected on the system oil return pipe, the ratio of system, pressure is controlled by servomotor, servo electric-control system is according to original pressure, flow signal, calculate the back and give rotating speed and the torque of servomotor to be fit to, like this during operate as normal, noise obviously reduces, set up good working environment, reduced the drive motors working time simultaneously, thus the electric energy loss when having realized reducing injection machine work, improve utilization rate of electrical, energy-saving and emission-reduction.
