Description of drawings
Fig. 1 is embodiment's schematic representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
A kind of vacuum automation control system; Comprise vacuum measuring instrument, main vacuum pump and drive the inverter motor that is connected with it; The degree of vacuum electrical signal of vacuum measuring instrument is connected with the frequency variator of inverter motor; Comprise that also vacuum switch, appendage vacuum pump drive the inverter motor of connection with it, the output terminal of vacuum switch inverter motor therewith is connected.Appendage vacuum pump is at least one.Described vacuum measuring instrument is a vacuum transducer.
Under the working state, the selector switch of system has " manually " and " automatically " two kinds of patterns, earlier selector switch is set under the automatic mode, is come the operation of control apparatus again by the PLC program.Under auto state, main vacuum pump moves automatically; If degree of vacuum is lower than the setting value of vacuum switch, then appendage vacuum pump starts automatically, replenishes not enough degree of vacuum; As degree of vacuum reach that vacuum switch sets stop to be worth the time, appendage vacuum pump stops automatically.The degree of vacuum that vacuum pump detects according to vacuum transducer during operation, inverter motor is regulated rotating speed automatically, and frequency is at 15HZ---and 50HZ changes, and reaches energy-conservation and gets purpose with the stable system vacuum.
The motor start mode must be variable frequency starting and operation.Motor starter must make up with circuit breaker independently each other.Frequency variator must have malfunction alarm.Reserve the I/O signal contact of central monitoring system, comprise equipment operation, stop, signal such as equipment failure escape.
Vacuum pump is connected to circuit checker, like electric current, watt-hour meter, is used to monitor running, fault, motor excess current; Various button: as start, stop, resetting, emergency stop push button, scene/remote control option switches, hand/automatic selector switch; Be provided with touch screen and can check degree of vacuum, vacuum pump delivery temperature, vacuum pump working solution temperature, parameters such as running time, and realize the upper limit alarm function.
A gas water separation tank all is housed on each vacuum pump, and gas water separation tank is equipped with magnetic float liquidlevel meter, fluid infusion solenoid valve and draining solenoid valve.During ultralow or superelevation, fluid infusion solenoid valve and draining solenoid valve do not move when the water level in the gas water separation tank, and system can send warning.
Relief opening and working solution suction port at vacuum pump is equipped with temperature transmitter simultaneously.When delivery temperature, system alarm when the working solution temperature is too high, unit stops voluntarily when the temperature superelevation.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; But the those skilled in the art should be understood that; In the spirit and scope of the utility model that does not break away from appended claims and limited; In form with on the details the utility model is made various variations, be the protection domain of the utility model.
