Abstract
The utility model discloses an open and stop device for air compressor machine electric machine control relates to the technical field of air compressor machine, thereby switch on or break off motor starting circuit's temperature detect switch S2, motor M and parallelly connected branch road no. 1 and branch road no. 2 including power V, switch S1, through the induction machine temperature variation, this branch road no. 1 is including the transformer T, normally closed contact KT1 and the circular telegram time lagged type relay KT that establish ties, and the branch road is two including the normally open contact KT2 and the green emitting diode LED that establish ties. Through selecting for use the transformer can make the voltage ware start under the lower voltage environment as required, reach the effect that the buffering starts, also reduced the loss of the energy when reducing mechanical loss, be favorable to lengthening the life of motor.
Description
Technical field
This utility model relates to the technical field of air compressor machine, is specifically related to a kind of start stop apparatus controlled for air compressor motor.
Background technology
Air compressor machine is driven by motor, in the work process of air compressor machine, the work load of motor is bigger, especially the running voltage that motor load is higher when moment starts, moment start produce high pressure substantially increase the loss of electric machine, be unfavorable for extend motor service life, and startup stage voltage often higher than actual demand, thus causing the waste of the energy, it is unfavorable for energy-saving and emission-reduction.
On-delay type relay refers to after adding the actuating signal that (or removing) inputs, its output circuit need to pass through the correct time specified and just produce a kind of relay of saltatory change (or contact action), is a kind of control electrical equipment utilizing electromagnetic principle or theory of mechanics to realize delays time to control.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model aims to provide a kind of start stop apparatus controlled for air compressor motor, the working strength of motor in start-up course is controlled, thus reaching energy-conservation effect.
For achieving the above object, this utility model adopts the following technical scheme that
Motor start circuit, this motor start circuit include power supply V, switch S1, by induction machine variations in temperature thus the branch road one of the temperature detect switch (TDS) S2 of the motor start circuit that is turned on or off, motor M and parallel connection and branch road two, this branch road one includes transformator T, normally-closed contact KT1 and the on-delay type relay K T of series connection, and branch road two includes normally opened contact KT2 and the LED of series connection.
Preferably, the LED of employing is green LED LED.
The beneficial effects of the utility model are in that: when Guan Bi switch S1 is to start motor start circuit, motor starts under power supply V and the coefficient environment of transformator T, the time rear motor that extends through setting just carries out normal operation under the environment of power supply V, and show normal duty by green LED, by selecting transformator T that voltage device can be made to start under relatively low voltage environment as required, reach the effect of buffer starting, decrease the loss of the energy while reducing mechanical loss, be conducive to extending the service life of motor;Change according to the motor feels hot situation; physical change is there is therewith inside temperature detect switch (TDS) S2; thus reaching the circuit that is turned on or off; when the motor feels hot abnormal time can disconnecting circuit in time; leave the motor off work; to the motor feels hot, situation carries out monitoring in real time and motor is realized overtemperature protection temperature detect switch (TDS) S2, extends the service life of motor further.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of start stop apparatus controlled for air compressor motor of this utility model.
Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, this utility model is described further:
As shown in Figure 1, a kind of start stop apparatus controlled for air compressor motor, including power supply V, switch S1, by induction machine variations in temperature thus the branch road one of the temperature detect switch (TDS) S2 of the motor start circuit that is turned on or off, motor M and parallel connection and branch road two, this branch road one includes transformator T, normally-closed contact KT1 and the on-delay type relay K T of series connection, and branch road two includes the normally opened contact KT2 and green LED LED of series connection.
On-delay type relay K T refers to after adding the actuating signal that (or removing) inputs, its output circuit need to pass through the correct time specified and just produce a kind of relay of saltatory change (or contact action), is a kind of control electrical equipment utilizing electromagnetic principle or theory of mechanics to realize delays time to control.
When this utility model uses, manual closing switch S1, now normally-closed contact KT1 Guan Bi, normally opened contact KT2 disconnects, and branch road one turns on, and motor M carries out low voltage starting under the power supply V power environment become with transformator T-shaped;After the prolongation duration set, normally-closed contact KT1 disconnects, and branch road one disconnects, normally opened contact KT2 closes, and branch road two turns on, and motor M enters normal operating conditions under the environment that power supply is V, green LED LED lights simultaneously, and prompting motor M enters normal operating conditions;When motor M heating causes that temperature is higher than setting value extremely, temperature detect switch (TDS) S2 disconnects, then motor start circuit disconnects, and green LED LED extinguishes, and prompting motor M quits work.
It will be apparent to those skilled in the art that can technical scheme as described above and design, make other various corresponding changes and deformation, and all these change and deformation all should belong within this utility model scope of the claims.
Claims (2)
1. the start stop apparatus controlled for air compressor motor, it is characterised in that including:
