Embodiment
See also Fig. 1 to Fig. 4, it is for the utility model provides a kind of intelligent air compressor 10, includes a gas storage barrel 20, a booster body 30, an electric motor 40, a pressure gauge 50 and a control unit 60.
This gas storage barrel 20 has some castors 22 and a carrying handle 24; Wherein, these castors 22 are located at this gas storage barrel 20 bottom sides, and in order to moving this gas storage barrel 20, this carrying handle 24 is located at this gas storage barrel 20 1 sides, carries out grasping for the user.
This booster body 30 connects these gas storage barrel 20 top sides, can will squeeze into this gas storage barrel 20 after the air compression, so that supercharging is carried out in these gas storage barrel 20 inside.
This electric motor 40 links this booster body 30, in order to drive this booster body 30 runnings.This electric motor 40 is to be selected from brush motor (brush motor), brushless motor (brushless motor) and switching magneti-resistance motor (switched-reluctance motor; SRM) wherein a kind of; In the present embodiment, this electric motor 40 is that choosing is an example with brushless motor (brushless motor).
This pressure gauge 50 is for digital pressure gauge (digital pressuregauge) and is located at this gas storage barrel 20, in order to detect the delivery pressure of this gas storage barrel 20.
This control unit 60 is for microprocessor (micro-processor) and is located at this electric motor 40 1 sides; This control unit 60 electrically connects this electric motor 40 and this pressure gauge 50, and this control unit 60 is feedback by this pressure gauge 50 and turned round to control this electric motor 40 in good time, guarantees that the delivery pressure of this gas storage barrel 20 maintains pressure constant state.
Wherein, above structure is identical with known air compressor, does not give unnecessary details in this appearance.
Of the present utility model being characterised in that:
This control unit 60 also includes one and judges that loop 62 and a timer (timer) 64 these judgement loops 62 are positioned at this control unit 60 and some discriminants 66 are arranged, respectively this discriminant 66 is to be triggered corresponding to different failure situations, judges for this control unit 60.When this timer 64 is triggered, can carry out timing to the specific control behavior 68 of this control unit 60.Thus, when this intelligent air compressor 60 in the running during, this judgement loop 62 can be via detecting this intelligent air compressor 10 states, with the failure judgement reason.
Via said structure, when this intelligent air compressor 10 starts, this control unit 60 can carry out initialization to this pressure gauge 50 and this electric motor 40 earlier, this electric motor 40 can be earlier to turn round according to desired speed, drive this booster body 30 runnings, with squeezing into after the air compression in this gas storage barrel 20, arrive a scheduled pressure value until delivery pressure.In the present embodiment, this pressure parameter includes a rated pressure value and a minimum pressure value; This scheduled pressure value is positioned at the differential pressure range that this minimum pressure value forms to this rated pressure value.
This intelligent air compressor 10 is during running, and when delivery pressure during greater than this rated pressure value, this control unit 60 can reduce these electric motor 40 rotating speeds and trigger this timer 64 and picks up counting; In Preset Time, these electric motor 40 rotating speeds can continue to reduce rotating speed to scale, less than this rated pressure value, and return back to this scheduled pressure value until delivery pressure.When Preset Time surpasses, delivery pressure is still greater than this rated pressure value; 40 of this electric motors can shut down, and this control unit 60 can detect the pressure in this gas storage barrel 20.If the pressure in this gas storage barrel 20 still continue to improve, promptly differentiate these electric motor 40 faults and be not subjected to this control unit 60 controls, this control unit 60 can show these electric motor 40 faults, personnel overhaul with the notice field operation.If the pressure in this gas storage barrel 20 do not reduce, promptly to differentiate these pressure gauge 50 faults and can not normally act on, this control unit 60 can show these pressure gauge 50 faults, personnel overhaul with the notice field operation.
When delivery pressure during less than this minimum pressure value, this control unit 60 can reduce these electric motor 40 rotating speeds and trigger this timer 64 and picks up counting; In Preset Time, these electric motor 40 rotating speeds can continue to increase rotating speed to scale, greater than this minimum pressure value, and return back to this scheduled pressure value until delivery pressure.When Preset Time surpasses, delivery pressure is still less than this minimum pressure value; 40 of this electric motors can shut down, and this control unit 60 can detect the pressure in this gas storage barrel 20.If the pressure in this gas storage barrel 20 still continues to reduce, promptly differentiating this gas storage barrel 20 may leak gas, and causes normally storage high pressure air, and this control unit 60 can show these gas storage barrel 20 faults, and personnel overhaul with the notice field operation.If the pressure in this gas storage barrel 20 does not improve, promptly to differentiate this this electric motor 40 and may damage and can not normally act on, this control unit 60 can show these electric motor 40 faults, personnel overhaul with the notice field operation.
If delivery pressure maintains scheduled pressure value, and between this minimum pressure value and this rated pressure value; 40 of this electric motors can shut down, and 60 of this control units can continue the pressure in this gas storage barrel 20 is detected, to monitor.If delivery pressure continues between this minimum pressure value and this rated pressure value, this 10 of intelligent air compressor can continue this state and be in standby.
Thus, this intelligent air compressor 10 is via the operation situation that continues this intelligent air compressor 10 of monitoring, and differentiates by the 62 pairs of operation situations in this judgements loop, guarantees this intelligent air compressor 10 energy normal operations.Moreover when this intelligent air compressor 10 broke down, this judgement loop 62 can further be differentiated failure cause, and shows fault message and type in real time, was beneficial to notify the field operation personnel directly to overhaul at the part of fault.
In sum, the utility model provides intelligent air compressor by said structure, and it can detect the differentiation failure situations automatically, and has the advantage of the stable output of constant voltage concurrently, overcomes existing person's shortcoming, the convenience that has the Security in the use and be beneficial to maintenance.
