Temperature Ⅰ.
1. Import and export of steam temperature precision value for not less than 1.0 on the Richter scale;
2. The outlet steam temperature control system of static error is not more than 1.5%.
Pressure Ⅱ.
1. The steam pressure of import and export value for accuracy is not lower than 1.0 on the Richter scale;
2. The outlet steam pressure control system of static error is not more than 1.5%.
Flow Ⅲ.
1. Steam flow and water flow reduction in value of precision is not lower than 1.5 on the Richter scale;
2. The integrating of steam flow rate and water flow reduction accuracy is not lower than 1.5 on the Richter scale are unlikely.
Ⅳ alarm.
Export range of steam temperature and pressure alarm Settings:
1. The upper limit for the full range of 10-100%
2. The lower limit for the whole range of 0-90%
Ⅴ. Response time
1. Automatic control: control system response time of 1 s or less;
2. The disc to fit exercise: when the regulator from full closed to fully open or from full open to full close, the fastest time: 25 s plus or minus 20% (special requirements shall be separately agreed).
(3) the products is introduced
RKG - Z - intelligent thermal control cabinet
(1) in the entire measuring range does not exist nonlinear error, according to the error of the measured temperature is not more than + / - 1 ℃ (thermal resistance error is not included); Error is not more than + / - 0.055 MPa pressure (pressure transducer error not included).
(2) instrument with automatic zero and automatic cold junction compensation, 18 months of continuous running no zero drift, under 0 ℃ to 50 ℃ environment guarantees accuracy.
(3) high precision digital display, all parameters are highlighted digital display, clear vision, be clear at a glance.
(4) high intelligent automatic control make you without manual operation, can keep best adjustment under the condition of the working condition of any state (of course manual operation function) is retained.
(5) due to the characteristics of multi-functional intelligent instruments, the actual debugging becomes quite simple. As long as the user of the secondary adjusting parameters and the lower limit alarm parameters through the instrument panel, plastic film light touch button easily to set and stored, and according to user requirements and production equipment, various parameters can be modified and adjusted follow one's inclinationsly.
6 meter site data stored by the electricity without losing information, and have each adjusting parameter setting can be locked by the password, to prevent accidental wrong operation, ensure the security of the instrument work normally.
2. The main performance parameters
(1) basic error: 0.5% f. S + 1 word.
(2) the display resolution: according to the range, can have four kinds of 0.001, 0.01, 0.1, 1.
(3) the PID parameter setting mode or intelligent self-tuning.
(4) and valve position limit to protect the output setting range: 0-100%.
(5) manually adjust the output range: 0-100%.
6. The internal cold junction compensation temperature range: 0 ℃ to 50 ℃.
7) conditions of use: ambient temperature: 0 ℃ to 50 ℃. Relative humidity: 90% or less.
Power supply voltage: 185 v - 185 vac; 5000 series: 90 v - 5000 vac. Power frequency: 50 + / - 2.5 H
