Structural characteristics
The new generation of automatic frequency conversion device is a new generation of energy-saving products designed on the basis of years of experience. It uses the highest brand of the United States Honeywell (Honeywell) high-end process regulator and Swiss ABB high-performance vector frequency converter, equipped with a dedicated frequency control pump, through adjusting motor speed technology to automatically adjust the temperature reduction water. Water supply. It not only has high control precision, but also saves energy, electricity and energy, and effectively protects the pump motor, which greatly prolongs the continuous service life of the pump motor. At the same time, the frequency conversion, due to its many functions, makes the pump motor automatically adjust the start and stop of the pump according to the actual working conditions in the course of use, and truly achieves full self-control. The application of dynamic control and frequency conversion technology in the temperature and pressure reduction device makes the temperature and pressure reduction device not only in the technical content, performance, energy saving are in the leading position.
Main performance indicators
1. the inlet steam pressure P1 is less than 5.4MPa, T1 is less than 485 degrees Celsius.
2. export volume Q:
The range of discharge Q of the unit is 10%Q to 100%Q, which is ideal in this range. If there is any special requirement, it can be negotiated with our technical department.
3. outlet steam pressure P2:
The adjusting accuracy of the outlet steam pressure P2 is not less than 2.5.
4. outlet steam temperature T2:
The adjustment accuracy of outlet steam temperature T2 is not less than 2.5.
5. noise:
When the device is in normal operation, the noise is measured at one meter downstream of the reducing temperature and pressure valve and one meter away from the pipe wall. The noise level is no more than 85 dB.
Scope of supply
The supply range of the unit is:
1. decompression system: temperature and pressure reducing valve, electric (pneumatic) actuator, throttling orifice, etc.
2. temperature reduction system: water pump, throttle valve, etc.
3. safety system: safety valve, check valve, etc.
4. piping system: steam pipe, transition tube, temperature reducing water pipe, etc.
5. Accessories: globe valves, bimetal thermometers and nozzles, pressure gauges and three-way valves, elbows, joints, flanges, gaskets, bolts, nuts, gaskets, etc.
