Embodiment
Technical scheme is described in further detail with reference to specific embodiment.
A kind of air compressor machine anomaly alarming device as shown in Figure 1, including relay module, contact switch module and alarm mould
Block, described relay module are connected to the input three-phase of motor including relay K1-K3, described relay K1-K3
In power supply；The contact switch module includes relay K1-K3 normally-closed contact switch K1-a, K1-b, K2-a, K2-b, K3-a
And K3-b, it is connected after described normally-closed contact switch K1-a, K2-a, K3-a is parallel with one another with alarm module, the normally-closed contact
Switch K1-b, K2-b, K3-b are connected after being serially connected with air compressor machine main line contact C；The alarm module triode BG1 and three
Pole pipe BG2, the triode BG1 base stage are connected with resistor R1 one end, and the other end connection of the resistor R1 is normally closed
Contact switch K1-a, K2-a, K3-a one end, the colelctor electrode of the triode BG1 are connected with resistor R2 one end, the electricity
The resistance device R2 other end is connected with normally-closed contact switch K1-a, K2-a, K3-a other end, the emitter stage of the triode BG1
It is connected in parallel to relay K4 and diode；The base stage of the triode BG2 is connected with resistor R3, the triode BG2's
Colelctor electrode is connected with resistor R4, contact switch K4 and contact switch K5, is connected between the resistor R3 and resistor R4
Pressure switch of air compressor, the emitter stage of the triode BG2 are connected in parallel to relay K5 and diode, the contact switch K4
Alarming horn and alarm lamp are also associated with contact switch K5.
Further optimization as above-described embodiment：
Preferably, the relay K1-K3 selection 220V AC relays MY2NJ；Relay K4, K5 select 12V DC relay
MY2NJ。
Preferably, the resistor R1-R4 uses 10K resistances.
Preferably, the alarming horn selects direct current 12V self-sounding loudspeaker, and alarm lamp carries the lamp of flicker with direct current 12V.
K1, K2, K3 are connected in motor input power circuit in figure.It is made up of three normally-closed contacts K1-a, K2-a, K3-a
Detection switch.When air compressor motor runs well.The all off-states of K1-a, K2-a, K3-a, alarm do not work.
As contactor C exceptions in main line or civil power phase failure alarm ring warning lamp flash.Another group of contact K1-b, K2-
B, it is connected in parallel on after K3_b series connection in starting switch, leaves the motor off operating.BG1 must be conducted simultaneously.Alarming horn and alarm lamp
Work.Inform and stop pneumatic compression devices in advance.And for example many reasons motor circuit is normal but driving belt is broken or air compressor machine itself
