Detailed description of the invention
A kind of engine vacuum extracts energy-storage system as shown in Figure 1, provides vacuum for the use vacuum source device on automobile or equipment, including electromotor 7, vacuum power accumulating device 1, controller 9 and use vacuum source equipment 10；Being connected by vacuum line I 2 between air inlet pipeline and the vacuum power accumulating device 1 of electromotor 7, vacuum power accumulating device 1 and use vacuum source equipment 10 are connected by vacuum line II 6；Equipped with pressure transducer I 3 and pressure transducer II 5 on vacuum line I 2, vacuum line I 2 is provided with between pressure transducer I 3 and pressure transducer II 5 vacuum solenoid I 4；Vacuum line II 6 is provided with vacuum solenoid II 11, is provided with cooling-water temperature sensor 8 in electromotor 7；
Pressure transducer I 3, pressure transducer II 5, vacuum solenoid I 4, vacuum solenoid II 11 and cooling-water temperature sensor 8 are connected with controller 9 line respectively.
Controller 9 receives the temperature signal of coolant in electromotor 7 by cooling-water temperature sensor 8, this temperature signal is for judging whether electromotor 7 is in the state being suitable for vacuum power accumulating device 1 extracting vacuum, as state meets, controller 9 judges the pressure differential at vacuum solenoid I 4 two ends again through pressure transducer I 3 and pressure transducer II 5, when the pressure differential limit value that pressure differential is preset more than controller 9, controller 9 controls vacuum solenoid I 4 and opens, vacuum solenoid II 11 cuts out, the air inlet pipeline of electromotor 7 starts vacuum power accumulating device 1 evacuation, when pressure differential is less than or equal to preset pressure differential limit value, controller 9 controls vacuum solenoid I 4 and vacuum solenoid II 11 cuts out.Under the effect of controller 9, engine vacuum extract that energy-storage system can realize going round and beginning again to vacuum power accumulating device 1 extracting vacuum, thus realizing cyclically for using vacuum source equipment 10 to provide vacuum.Wherein, pressure transducer I 3 can be disposed on any vacuum line between vacuum solenoid I 4 and vacuum solenoid II 11 or on vacuum power accumulating device 1.Pressure transducer II 5 can be disposed on any vacuum line between vacuum solenoid I 4 and electromotor 7 inlet valve or on any air inlet pipeline.The spatial form of vacuum power accumulating device 1 is not necessarily cylinder, and it can be possess a constant volume and be suitable for any hollow solid with some strength and rigidity arranged in any space of automobile, makes full use of inner space of vehicle.
Preferably, this controller 9 also has identification system, vacuum source equipment 10 is used to be connected with the input of controller 9 by circuit, when controller 9 receives the use vacuum signal that use vacuum source equipment 10 sends, by identification system, controller 9 judges whether the vacuum in vacuum power accumulating device 1 meets instructions for use, as met requirement, controller 9 controls vacuum solenoid II 11 and opens, for using vacuum source equipment 10 to provide vacuum.
Preferably, above-mentioned cooling-water temperature sensor 8 is original cooling-water temperature sensor in additional cooling-water temperature sensor or electromotor 7.
It is as follows that engine vacuum extracts energy-storage system specific works process:
nullAfter electromotor 7 starts，The vacuum line I 2 being connected with electromotor 7 air inlet pipeline produces vacuum，Controller 9 detects the temperature signal of coolant in electromotor 7 by cooling-water temperature sensor 8 simultaneously，When in electromotor 7, the temperature of coolant reaches the preset temperature limit of controller 9，Show that electromotor 7 possesses the initial condition to vacuum power accumulating device 1 evacuation，Now，Controller 9 passes through the pressure differential at pressure transducer I 3 and pressure transducer II 5 detection vacuum solenoid I 4 two ends being arranged on vacuum tube I 2，When the pressure differential limit value that the pressure differential at vacuum solenoid I 4 two ends is preset more than controller 9，Sent to vacuum solenoid I 4 by controller 9 and open control instruction，Vacuum solenoid 4 opens (now the vacuum solenoid II 11 on vacuum line II 6 cuts out)，System starts extracting vacuum，The pressure of vacuum power accumulating device 1 is gradually lowered，When the pressure differential limit value that the pressure differential at vacuum solenoid I 4 two ends is preset equal to or less than controller 9，Controller 9 sends closing control instruction to vacuum solenoid I 4，Vacuum solenoid I 4 cuts out，Electromotor 7 stops vacuum power accumulating device 1 evacuation.
When controller 9 detects the pressure differential at the vacuum solenoid I 4 two ends pressure differential limit value preset more than controller 9 again, controller 9 again sends to vacuum solenoid 4 and opens control instruction, vacuum solenoid 4 is opened, system starts again at extracting vacuum, so repeatedly, vacuum power accumulating device 1 is finally made to reach higher vacuum, thus for automobile needing the equipment of vacuum source provide vacuum.After controller 9 receives and uses the use signal that vacuum source equipment 10 sends, vacuum solenoid II 11 is opened, vacuum power accumulating device 1 provides vacuum (now vacuum solenoid I 4 cuts out) for using vacuum source equipment 10, along with the vacuum of vacuum power accumulating device 1 is gradually lowered until leveling off to zero, controller 9 cuts out electromagnetic valve II 11, detect the pressure differential at vacuum solenoid I 4 two ends simultaneously, when the condition is satisfied, open electromagnetic valve I 4, electromotor 7 is vacuum power accumulating device 1 evacuation, thus vacuum drawn energy-storage system enters next extracting vacuum and provides the new cycle of operation of vacuum source.
When vacuum power accumulating device 1 utilizes electromotor to work under the parts work compounds such as controller 9, vacuum solenoid, pressure transducer, cooling-water temperature sensor, the negative pressure of air inlet pipeline is to its extracting vacuum, store vacuum, thus for automobile needing the equipment of vacuum provide vacuum.Therefore, this system can replace vacuum pump and corresponding energy storage device provides vacuum for automobile use vacuum source equipment, it is achieved simplifies and uses vacuum source device structure and energy-conservation target on automobile, and improves economy.
