Abstract
The utility model provides a motor energy-saving system which includes a resistor and a motor and is characterized in that a variable frequency energy-saving device is arranged between the resistor and the motor; and the resistor is arranged on a coil of an injection machine output pressure tuning valve. The advantage is that corresponding rotation speed and torque current are automatically output along with the pressure, so the electric power is saved, and the wear of an injection machine rotary part is reduced.
Description
Technical field
The utility model relates to many actions equipment electrical machine energy-saving field, particularly a kind of energy conserving system for electric motor of injection machine zero load and underloading.
Background technology
In injection molding machine equipment, work-piece cools is one of various motion.Most domestic injection molding machine motor when work-piece cools is in Light Condition at present, and capacitance reactive compensation is energy-conservation limited.The general power of the motor of injection molding machine is all larger, and just the electric energy of no-load consumption every day will be a lot, presses the work in 24 hours of the actual test of injection molding machine 30KW motor whole day, and every day, the electric energy of no-load consumption reached more than 70 degree.Zero load not only consumes electric energy, and increases equipment attrition, reduces the useful life of equipment unit.
Present injection molding machine does not also have simply and easily, and mode solves the large problem of injection molding machine energy consumption.
Summary of the invention
The purpose of this utility model is for above-mentioned existing problems, a kind of energy conserving system when waiting for for many actions equipment is unloaded is provided, this scheme apparatus is simple, easy to implement, make unloaded bide one's time reduction rotating speed and the electric current of waiting of many actions equipment, reduce and wait the power consumption of biding one's time, reduce the wearing and tearing of equipment unit, replace capacitance compensation and reach energy-saving and cost-reducing effect.
The technical solution of the utility model: a kind of electrical machine energy-saving system, comprise resistance, motor, a frequency-variable energy-saving device is set between resistance and motor.
Further, described resistance is arranged on the tuning valve winding of injection molding machine output pressure.
Flow process of the present utility model: by the variation that is arranged on resistance on the tuning valve winding of injection molding machine output pressure and detects pressure, deliver to frequency-variable energy-saving device.The control frequency-variable energy-saving device is pressed output frequency and the electric current of the variation adjustment motor of injection molding machine pressure-tuned electric current.Rotating speed by the control motor, make the Amount of actual oil supply of oil pump consistent with the working flow demand of injection molding machine, guaranteeing under the stable prerequisite of system pressure, the original overflow phenomena of injection molding machine is controlled to minimum state, the actual flow of oil pump is proportional to the rotating speed of motor, therefore the power output of oil pump also is proportional to the rotating speed of motor, thus significantly saves energy consumption; Simultaneously, frequency-variable energy-saving device can be brought up to the power factor of oil pump motor more than 95%, effectively improves power grid quality, reduces reactive power consumption.
Advantage of the present utility model: automatically follow the corresponding rotating speed of Output pressure and corresponding torque current.Saves energy reduces the wearing and tearing of injection molding machine rotatable parts.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure:
1, resistance 2, frequency-variable energy-saving device 3, motor
Embodiment
As shown in Figure 1, a kind of electrical machine energy-saving of the utility model system comprises resistance 1, motor 3, it is characterized in that, a frequency-variable energy-saving device 2 is set between resistance 1 and motor 3.
Further, described resistance 1 is arranged on the tuning valve winding of injection molding machine output pressure.
By the variation that is arranged on resistance 1 on the tuning valve winding of injection molding machine output pressure and detects pressure, deliver to frequency-variable energy-saving device 2.Control frequency-variable energy-saving device 2 is pressed output frequency and the electric current of the variation adjustment motor 3 of injection molding machine pressure-tuned electric current.Rotating speed by control motor 3, make the Amount of actual oil supply of oil pump consistent with the working flow demand of injection molding machine, guaranteeing under the stable prerequisite of system pressure, the original overflow phenomena of injection molding machine is controlled to minimum state, the actual flow of oil pump is proportional to the rotating speed of motor, therefore the power output of oil pump also is proportional to the rotating speed of motor, thus significantly saves energy consumption.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
Claims (2)
1. an electrical machine energy-saving system comprises resistance, motor, it is characterized in that, a frequency-variable energy-saving device is set between resistance and motor.
2. a kind of electrical machine energy-saving according to claim 1 system is characterized in that described resistance is arranged on the tuning valve winding of injection molding machine output pressure.
