Therefore, according to the current working state of the injection molding machine, such as opening mold, mold clamping, rubber injection, material return, ejection, etc., as well as pressure and speed setting requirements, the speed of the oil pump is automatically adjusted, and the oil pump oil supply is adjusted to make the oil pump. The actual fuel supply and the actual load flow of the injection molding machine can be kept in line with each other at any working stage. In this way, the overflow portion of the hydraulic oil will be eliminated, the overflow phenomenon will be completely eliminated, the oil pump output will be reduced, and the power consumption of the oil pump motor will be saved.
The frequency conversion energy-saving controller uses the principle of controlling the oil supply motor at different stages to provide the corresponding rotational speed, so that the quantitative pump becomes an energy-saving variable displacement pump, so as to achieve the best energy-saving state of the injection molding machine.
Significant energy savings: up to 30%-65%
Optimize electrical facilities: Reducing transformer load, reducing capacity expansion fees for disconnected plants and new plants
Extend the life of the whole machine: Saver control speed is stable, soft start (no grid shock), reduce the vibration of the open mold, avoid equipment impact, reduce the oil temperature, extend the service life of the seal, and thus extend the life of the whole machine
Easy to operate: no need to adjust the energy saver in production, automatic tracking control, and a variety of protection functions, simple, safe and convenient
Reduce noise: The noise of the equipment is reduced by about 10DB after the transformation, the equipment movement is more stable, and the operating environment is improved
Flexible conversion: The frequency conversion cabinet is convenient for the user to switch from industrial frequency to frequency conversion or frequency conversion to industrial frequency at any time.
