Description
Technical field
The utility model belongs to crane power system, and what be specifically related to is a kind of with energy accumulation device for fly wheel hoisting crane hybrid power system.
Background technology
Portal crane is in weight decline, deceleration operation process, and for preventing weight gravitate generation fast free from falling, the general regenerative electric energy adopting braking resistor consumption to be produced by load dragging motor, provides resistance by consumed energy to weight.If the electric energy that motor running produces under generating state is reclaimed, closed-center system now can be utilized to store feedback energies such as potential energy, use for power consumption peak phase during lifting, significant energy-saving effect can be reached like this, also can reduce the impact of sudden applied load to diesel engine simultaneously, thus improve the service efficiency of power system.
Summary of the invention
The utility model provides a kind of with energy accumulation device for fly wheel hoisting crane hybrid power system, by absorbing the feedback energy, to be mixed and the system effectiveness of propulsion source is optimized, meet the energy requirement of Construction Machinery System by closed-center system with other energy.
The technical solution adopted in the utility model is:
A kind of with energy accumulation device for fly wheel hoisting crane hybrid power system, comprise driving engine, accumulator, electrical generator, motor, distributing means for power supply, the first controller, second controller and actuating unit; Driving engine, electrical generator are connected with distributing means for power supply respectively, and motor, distributing means for power supply and actuating unit are connected with the first controller respectively, and motor, electrical generator, accumulator are connected with second controller respectively; Wherein accumulator is energy accumulation device for fly wheel, it comprises a vacuum vessel, is disposed with head bearing, electrical motor from top to bottom in container, flywheel and lower bearing, electrical motor is connected with the power electronic equipment being arranged on vacuum vessel outside, and wherein head bearing and lower bearing are contactless magnetic bearings.
An engine output part flows to actuating unit by distributing means for power supply, and another part then drives electrical power generators.Its electric energy sent is controlled by controller and flows to motor or accumulator, sends actuating unit to together with the drive torque that motor and distributing means for power supply produce.The principle of work of accumulator is: rotated from the electric energy of outside input by power electronic equipment driving motor, electrical motor flywheel driven rotates, and electrical power storage is mechanical energy by flywheel, with the form stored energy of kinetic energy.When external loading needs energy, flywheel drive electrical generators rotates, and kinetic energy is transformed to electric energy and exports.Flywheel operates under vacuum conditions, and the bearing of use is contactless magnetic bearing.Because flywheel activates by braking, its accumulation of energy time, namely the time of flywheel turns is limited, is specially adapted to the occasion that construction machinery and equipment actuating unit rises continuously and declines.
This hybrid power system can make driving engine, motor, electrical generator obtain more Optimized Matching, structurally ensure that system works is at optimum state, therefore more easily realizes the target of emissions reduction and fuel oil consumption.
