Main features:
1. When the sample water pressure at a certain point exceeds 0.8MPa, the safety valve will automatically releaseEnsure the safety of equipment and personnel.
2. The temperature inspection instrument displays a temperature value with an error of ≤± 1 ℃. real time displayVarious water temperatures.
3. The over temperature alarm value and protection temperature value can be set on the temperature inspection instrument by oneselfSet (usually at 40-45 ℃), the water sample temperature reaches or exceeds the set temperatureWhen the temperature is high, the over temperature protection component (solenoid valve) will activate and cut off the correspondingWater sample, and at the same time, transmit the overheating signal of the sample water to the demand side control remotelyManufacturing system.
4. When the inlet pressure of cooling waterWhen the force is below the lower limit (0.15MPa) or the flow rate is below the set value, the temperature inspection instrumentClose all water and electricity plant magnetic valves, cut off the water sample, and at the same time remotely transmit the undervoltage or cut-off signal to the demandFang Control System.
Working conditions:
1. Environmental temperature: 5-45 ℃.
2. Relative temperature: ≤ 85%.
3. The working environment should be free of conductive dust and corrosive gases.
4. A place without severe vibration or explosion hazards.
5. Power supply: single-phase three (fire, zero, ground) AC220V (± 10%), 50Hz/60Hz, 1kW.
Note: After the equipment is put into operation, the working power supply of the temperature inspection instrument must not be disconnected.
Technical indicators:
1. When the water sample flow rate is ≥ 1500ml/min under normal working conditions, the water sample temperature≤40 ℃, pressure≤0.1~0.7MPa (sample water temperature varies with on-site equipment)
The temperature of the cooling water varies depending on its temperature.
2. Ensure manual sampling flow rate at each sampling point≤500ml/min, The sampling flow rate of each instrument is ≥ 300ml/min.
