Abstract
The invention provides a control device for a small compressor. The control device comprises a box. A PLC, a temperature controller, a switching power source and a thermocouple connecting wire are arranged in the box. A motor hole is formed in the box, and a power binding post of the small compressor stretches in the box from the motor hole. The temperature controller is connected with a thermocouple through the thermocouple connecting wire, and the thermocouple is located on a high-pressure bottle of the small compressor. The PLC is connected with the temperature controller and further connected with a power source wire of the power binding post of the small compressor. The switching power source is connected with the PLC for supplying power. According to the control device, the temperature of the high-pressure bottle of the small compressor is measured through the thermocouple, temperature signals are received by the temperature controller and sent to the PLC, on-off of the power source wire of the power binding post of the small compressor is controlled by the PLC, and therefore starting and stopping of the small compressor can be automatically controlled under the condition of temperature changes, manpower is saved, and the work efficiency is improved.
Description
Technical field
The invention belongs to air compressor production field, particularly relates to a kind of control device for being controlled by little air compressor.
Background technology
Little air compressor is used for filling high pressure gas, pressurized air is filled with other equipment, the structure of little compressor is provided with the bomb filling high pressure, but, after little compressor operating for some time, the temperature of bomb can be raised to very high, at this time just must close little compressor, stop work, until temperature return is to standard state.
Said process does not have good Controlling System at present, can only pass through Artificial Control, cause working efficiency lower like this, do not meet the needs of modernization industrial production.
Summary of the invention
The problem that the invention to be solved is a kind of little compressor control device of design, it is possible to the startup of automatic control compressor is closed, and ensures production efficiency.
In order to achieve the above object, the technical scheme that the invention is taked is: a kind of little compressor control device, it is characterised in that: comprising box body, described box body inside is provided with PLC, temperature regulator, switch power supply, thermopair wire; Described box body has motor hole, and described little compressor power terminal stud stretches into from motor hole; Described temperature regulator connects the thermopair being positioned at little compressor bomb place by thermopair wire; Described PLC connects temperature regulator, also connects the power supply wiring of little compressor power terminal stud; Described switch power supply connects PLC and powers.
Further, the power supply wiring of described little compressor power terminal stud and temperature regulator, switch power supply is the same draws from the power supply bus of box body.
Further, described PLC connects touch-screen, carries out operation control by touch-screen.
The useful effect of the invention is: little compressor power terminal stud 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 the power supply of convenient directly control motor; The invention measures the temperature of little compressor bomb by thermopair, receive temperature signal by temperature regulator and send PLC, PLC controls the power supply wiring break-make of compressor power terminal stud, the automatic control that the startup under little compressor temperature changing conditions is closed can be realized, save artificial, it is to increase working efficiency.

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 box body inside is provided with PLC, temperature regulator, switch power supply, thermopair wire; As shown in Figure 1, described box body 1 has motor hole 2, and described little compressor power terminal stud stretches into from motor hole; As shown in Figure 3, described temperature regulator connects the thermopair being positioned at little compressor bomb place by thermopair wire; Described PLC connects temperature regulator, also connects the power supply wiring of little compressor power terminal stud; Described switch power supply 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 terminal stud and temperature regulator, switch power supply is the same draws from the power supply bus of box body.
Little compressor power terminal stud 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 the power supply of convenient directly control motor; The invention measures the temperature of little compressor bomb by thermopair, receive temperature signal by temperature regulator and send PLC, PLC controls the power supply wiring break-make of compressor power terminal stud, it is possible to realize the automatic control that the startup under little compressor temperature changing conditions is closed.
Above an embodiment of the invention is described in detail, but described content is only the better embodiment of the invention, the practical range for limiting the invention can not be considered to. All equalizations done according to the invention application range change and improvement etc., all should still belong within the patent covering scope of the invention.
