Abstract
The utility model belongs to the technical field of electrical control and proposes an electrical control device for an air compressor. The electrical control device has the main characteristics that a hardware system adopts a PLC (Programmable Logic Controller); a text display and an accessory circuit are connected with the PLC; and the PLC is connected with a signal input device and a signal output device of the air compressor. The electrical control device for the air compressor can effectively solve the problem that the electrical control part of the existing air compressor is easily out of control.
Description
Technical field
The utility model belongs to the Electrical Control Technology field, relates to a kind of air compressor electric control equipment.
Background technique
Existing a kind of air compressor is that high-voltage motor drags, its electric control system breaks down easily after using the short period and damages, mainly be that its touch screen thickens unclear and can not operate, and this touch screen and master controller are incorporate, then price is more expensive as if integral replacing, and time quality guarantee period is short, even integral replacing also similar fault may occur in a short time.
Summary of the invention
The inventor is in the routine work process, find that its electric control system of air compressor that existing high-voltage motor drags exists above-mentioned defective, through improving test, technical problem to be solved in the utility model provides a kind of air compressor electric control equipment that can make the normal operation of air compressor.
For solving the problems of the technologies described above, technical solution adopted in the utility model is that the structure of this air compressor electric control equipment comprises hardware system, hardware system is PLC, connects text display and accessory circuit on PLC, and PLC is connected with signal output apparatus with the signal input apparatus of air compressor.
The utility model adopts technique scheme, by the control of hardware system PLC, has guaranteed the stability and normal use of air compressor electrical control, has satisfied the needs of producing, and the normal operation of producing for enterprise provides guarantee.
Description of drawings
Fig. 1 represents the structural representation of the utility model air compressor electric control equipment.
Embodiment
Specify below in conjunction with the structure of accompanying drawing the utility model air compressor electric control equipment.
The structure of the utility model air compressor electric control equipment comprises hardware system PLC, PLC adopts Siemens S7-200PLC, on PLC, connect text display and accessory circuit, text display adopts Siemens TD400 text display, PLC is connected with signal output apparatus with the signal input apparatus of air compressor, software systems of the present utility model adopt the S7-200 programming software to carry out programming, install to linking route behind the S7-200PLC under institute's written program.
The utility model Control work principle: control system is come the air displacement of automatic control compressor according to compressed-air actuated consumption, keep compressor to work under predetermined the highest minimum exhaust pressure scope, this control system is that the variation in pressure of pneumatically reaches automatic control.After the compressor start, be in no-load running, when oil pressure is raised to 0.2-0.3MP, and delivery temperature reaches 50 ℃, and the solenoid valve on its easing valve gets electric, and easing valve is in full-gear, the air-breathing work of compressor starts, the pressure that separates in the oil tank raises gradually, and compressor is discharged pressurized air, and compressor is in the full load running state.When gas consumption during less than specified air displacement, system pressure raises, when gas consumption reduced, compressor operating pressure reached the CLV ceiling limit value of default, the PLC output signal, solenoid valve dead electricity on the easing valve, the easing valve intakeport is closed, and the compressor unloading operation is when dropping to the lower limit of default as pressure, solenoid valve on the easing valve gets electric, the work above repeating.
Its electric motor protecting has: phase sequence, prevent compressor reverse rotation, open-phase protection function, motor heat overload protection function.
The air compressor outlet has the high temperature protection function: when compressor exhaust temperature surpasses setting value (110 ℃); by the temperature sensor probe control temperature electric contact action that is connected on place, main exhaust aperture; signal input PLC shuts down through PLC program control motor, makes the compressor emergency shutdown.
Oil strainer stops up reports to the police: when oil strainer stopped up, when pressure reduction reached 0.1-0.15MP, the differential pressure transmitter device action was passed to display alarm information on the TD400 touch screen through PLC, and compressor is not shut down.
Air intake filter stops up reports to the police: when air intake filter stopped up, the differential pressure transmitter device action was passed to display alarm information on the TD400 touch screen through PLC, and compressor is not shut down.
The low protection of cooling water flow: when water cooler lack of water or water flow are low, the water flow switch motion, if water flow is not also recovered normally in 20S, and delivery temperature is then sent halt command power failure motivation, compressor shutdown by PLC when being raised to 110 ℃.
The utility model has solved the easy out of order problem of existing air compressor electric control system through on probation.
Claims (1)
1. an air compressor electric control equipment comprises hardware system, it is characterized in that hardware system is PLC, connects text display and accessory circuit on PLC, and PLC is connected with signal output apparatus with the signal input apparatus of air compressor.
