Abstract
The utility model proposes a kind of little compressor control device, comprise box body, described tray interior is provided with PLC, temperature controller, switch power, thermocouple connecting line; Described box body has motor hole, and described little compressor power wiring terminal stretches into from motor hole; Described temperature controller connects the thermocouple being positioned at little compressor bomb place by thermocouple connecting line; Described PLC connects temperature controller, also connects the power supply wiring of little compressor power wiring terminal; Described switch power connects PLC and powers.The utility model measures the temperature of little compressor bomb by thermocouple, receive temperature signal by temperature controller and be sent to PLC, PLC controls the power supply wiring break-make of compressor power wiring terminal, the automatic control that the startup under little compressor temperature situation of change is closed can be realized, save artificial, improve working efficiency.
Description
Technical field
The invention belongs to air compressor production field, particularly relates to a kind of control gear for controlling little air compressor.
Background technique
Little air compressor is used for filling pressurized gas, pressurized air is filled with other equipment, the bomb filling high pressure is provided with in the structure of little compressor, but, after little compressor operating a period of time, the temperature of bomb can be raised to very high, at this time just must close little compressor, quit work, until temperature return is to normal state.
Said process does not have good control system at present, can only pass through manual control, cause working efficiency lower like this, not meet the industrial needs of modernization.
Summary of the invention
The problem that the invention will solve be design a kind of little compressor control device, can automatic control compressor startup close, ensure manufacturing efficiency.
In order to achieve the above object, the technological scheme that the invention is taked is: a kind of little compressor control device, is characterized in that: comprise box body, and described tray interior is provided with PLC, temperature controller, switch power, thermocouple connecting line; Described box body has motor hole, and described little compressor power wiring terminal stretches into from motor hole; Described temperature controller connects the thermocouple being positioned at little compressor bomb place by thermocouple connecting line; Described PLC connects temperature controller, also connects the power supply wiring of little compressor power wiring terminal; Described switch power connects PLC and powers.
Further, the power supply wiring of described little compressor power wiring terminal and temperature controller, the same power bus from box body of switch power is drawn.
Further, described PLC connects touch screen, carries out operation control by touch screen.
The beneficial effect of the invention is: little compressor power wiring terminal is introduced in the invention perforate, and one is save space, enables the invention directly sit on the motor of little compressor, and two is convenient power supplies directly controlling motor; The invention measures the temperature of little compressor bomb by thermocouple, receive temperature signal by temperature controller and be sent to PLC, PLC controls the power supply wiring break-make of compressor power wiring terminal, the automatic control that the startup under little compressor temperature situation of change is closed can be realized, save artificial, improve working efficiency.

Fig. 1 is the cassette shapes schematic diagram of the invention.
Fig. 2 is the main circuit diagram of the invention.
Fig. 3 is the structural representation of the invention.
Wherein:
1, box body; 2, motor hole.
Embodiment
Below in conjunction with specific embodiment, the invention is described further.
The invention comprises box body 1, and described tray interior is provided with PLC, temperature controller, switch power, thermocouple connecting line; As shown in Figure 1, described box body 1 has motor hole 2, and described little compressor power wiring terminal stretches into from motor hole; As shown in Figure 3, described temperature controller connects the thermocouple being positioned at little compressor bomb place by thermocouple connecting line; Described PLC connects temperature controller, also connects the power supply wiring of little compressor power wiring terminal; Described switch power connects PLC and powers, and described PLC connects touch screen, carries out operation control by touch screen.
As shown in Figure 2, the power supply wiring of described little compressor power wiring terminal and temperature controller, the same power bus from box body of switch power is drawn.
Little compressor power wiring terminal is introduced in the invention perforate, and one is save space, enables the invention directly sit on the motor of little compressor, and two is convenient power supplies directly controlling motor; The invention measures the temperature of little compressor bomb by thermocouple, receive temperature signal by temperature controller and be sent to PLC, PLC controls the power supply wiring break-make of compressor power wiring terminal, can realize the automatic control that the startup under little compressor temperature situation of change is closed.
Above an embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, the practical range for limiting the invention can not being considered to.All equalization changes done according to the invention application range with improve, within the patent covering scope that still all should belong to the invention.
