Background technology
In heat treating equipment, other power components such as frequency conversion thyristor, electron tube, capacitor for electric induction heating system, inductive coil in when work since electric current to produce height greatly hot, must use recirculated cooling water that it is dispelled the heat, need the parts of cooling in time to cool off if the flow of chilled water reaches to require just can not to allow, cause heat build-up and cause these parts to burn out or performance decline; Bring great economic loss and waste of material to applying unit.
This utility model can monitor the present flow rate in each pipeline, and can set the minimum flow alarming value of respectively monitoring pipeline respectively; Discharge is lower than the setting flow in a certain pipeline, and this installs corresponding output port and warning port output alarm signal immediately.Applying unit staff can take measures according to alerting signal, avoids component wear and is producing raw-material waste.
For the water route device for monitoring pressure monitoring, flowmeter monitoring, flow switch monitoring are arranged.
Pressure monitoring device has following characteristics:
1, is easy to installation, simple in structure;
2 but when water-cooled element pipeline take place to stop up, pressure can't descend, just flow descends or does not have flow, and this moment, pressure monitoring device can not reported to the police, and the water-cooled short time will damage or performance descends but high-power water-cooled element can not get; So pressure monitoring device can not play good protection to high-power water-cooled element.
The flowmeter supervising device has following characteristics:
1, the flowmeter monitoring device is generally only exported electric signal, reach the purpose that flow must monitor and control, must mix the instrument of specialty and control, so the cost of investment height, one covering device needs the cost investment of units up to ten thousand, but also can only monitor the flow of single pipeline.
2, the flowmeter monitoring device is useful for the flow monitoring of large pipeline, and the pipeline of flexible pipe or little caliber is not easy to monitoring.
The flow switch monitoring device has following characteristics:
1, because pressure switch belongs to the mechanical magnetic switch, at the bottom of the sensitivity.
2, the pressure switch monitoring device can not carry out the accurate adjusting of alarming value with regard to the pipeline flow size.
The utility model content
The purpose of this utility model is the discharge measure and control device that has proposed in a kind of water-cooling system, to overcome many shortcomings of prior art, can carry out whole monitoring to the flow of different pipelines in the water-cooling system, and send warning according to abnormal conditions.
Technical solution of the present utility model is as follows:
Discharge measure and control device in a kind of water-cooling system is characterized in that, comprises being arranged in the water pipe line with the flow sensor that detects actual flow, being used for the controller and the warning port that send alerting signal according to the data on flows that detects and default alarm parameters; Described flow sensor output signal is to described controller; Described controller has the warning port.
Described controller comprises and is used to store the parameter storage unit of default alarm parameters and is used for relatively being somebody's turn to do the comparing unit of presetting alarm parameters and actual flow data; The output terminal of a described flow sensor of input termination of described comparing unit; Another input termination parameter storage unit of described comparing unit; The output terminal of described comparing unit port taking alarm.
As improvement, described flow sensor is a plurality of, is separately positioned in the different water pipe lines; Described controller also comprises a plurality of described parameter storage unit and a plurality of described comparing unit; Each flow sensor is connected with a parameter storage unit and a comparing unit correspondence respectively; The output terminal of a plurality of described comparing units all is connected with the warning port.Concrete structure as shown in Figure 2.
Described controller is device and circuit such as 51 series monolithics, Programmable Logic Controller (PLC), DSP or ARM and associated analog, digital circuit.
Thinking of the present utility model is: utilize a plurality of flow sensors respectively discharge in the pipeline of each high-power parts chilled water to be monitored; A plurality of flow sensor output signals (detected value) are given controller; Controller can also be set and respectively monitor pipeline minimum flow alarming value, and controller is handled signal (mainly being compare operation); Discharge is lower than and sets the corresponding output port of this device of flow value and warning port output alarm signal immediately in a certain pipeline.
Advantage of the present utility model and effect:
Water route monitoring devices such as this utility model and pressure monitoring, flowmeter monitoring, the flow switch monitoring following advantage that compared:
1, directly cooling water flow in the pipeline of needs monitoring is monitored the precision height of monitoring and control.
2, cost is low, and a covering device can be monitored the multichannel pipeline, and integrated cost is low.
3, each monitoring circuit alarming value can be set, and is independently of one another each other, when some loops temporarily do not need monitoring, this loop alarming value can be set at closed condition; Monitoring is continued in other loops, is not subjected to have closed the influence of closed loop.Therefore dirigibility is strong, is easy to expansion.
