Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, the air compressor originally with multiple motor 12 comprises control system, gas holder 13 and motor 12, the quantity of motor 12 has two at least, in the present embodiment, motor 12 has 5, comprises a mair motor and 4 auxiliary-motors, set-up of control system is on mair motor, the all corresponding one group of compressing mechanism of each motor 12, all controlled its working state of Systematical control of each motor 12, motor 12 inputs pressurized gas by compressing mechanism in gas holder 13.
Control system comprises drive controller, pressure detector 2 and calculator, and pressure detector 2 and calculator are all electrically connected the force value that is respectively used to detect in gas holder 13 and calculate respectively the continuous working period of each in running order motor 12 with drive controller.
As shown in Figure 2, compressing mechanism comprises cylinder 1, slide block 9 and crank 10, motor 12 driving crank 10 rotates, and the cylinder body of cylinder 1 offers the suction port 3 and relief opening 4 that are communicated with inner chamber of cylinder block, and suction port 3 and relief opening 4 place are respectively equipped with Aspirating valves 5 and outlet valve 6.Inner chamber of cylinder block is provided with piston 7 and piston rod 8, one end of described piston rod 8 is connected with piston 7, and the other end is connected with slide block 9, and slide block 9 is provided with connecting rod 11 relative to the opposite side of piston rod 8, the two ends of connecting rod 11 are rotationally connected with slide block 9 and crank 10 respectively, and motor 12 is brushless electric machine 12.
During work, pressure detector 2 detects the pressure state in gas holder 13 constantly, when pressurized air exports, air pressure in gas holder 13 lowers gradually, when the Pressure Drop in gas holder 13 is to a certain setting value, drive controller selects the motor 12 of respective amount to work according to the amplitude that required supplementary gas flow and air pressure reduce, when the gas that needs supplement is more or compressed-air actuated output flow is larger, the motor 12 starting a greater number works simultaneously, guarantee supplemented gas at short notice and met compressed-air actuated permanent output, the motor 12 that other are not activated is for subsequent use, otherwise the motor 12 that can start lesser amt works.When motor 12 is after continuous working period reaches set time; motor 12 for subsequent use can be started work; the above-mentioned motor 12 reaching the setting operating time is shut down; the motor 12 newly enabled and between the motor 12 that works replace one to one; same motor 12 is avoided to work long hours; the cumulative operation time of all motors 12 tends to balance as far as possible, improves the working life of motor 12.
When there is fluctuation change in compressed-air actuated output quantity, the quantity of all right timely adjustment work drive motor 12 of drive controller, close down part motor 12 or a part of motor 12 for subsequent use of interim increase startup, pass through the method, the force value that can control in gas holder is in a stationary value all the time, and the pressure of institute's delivery air is also more stable.
