High Temperature Regulator Understand The Characteristics And Detection Of Objects

High Temperature Regulator parameter tuning is to improve the dynamic and static characteristics of the closed-loop system, therefore, must be aware of the parameters of the control system before the dynamic and static characteristics of the system. Because the system is composed of two parts of the object and the control device, so should be in-depth understanding of the characteristics of the object and detection, the characteristics of the High Temperature Regulator. If you can test the characteristics of the controlled object is the best, if you do not have the test conditions, it should also be a rough estimate, such as the capacity, load changes, the length of time lag, the object with or without self-balancing ability In addition, you should also understand the process, control indicators, the operation process. For the use of field instruments will have to be carefully adjusted, check, make it meet the technical requirements. Only in the control of the object and the instrument used a comprehensive understanding, in order to correctly adjust the High Temperature Regulator parameters.

But also to see that the tuning High Temperature Regulator parameters can only be improved within a certain range of control system quality. If the system design is unreasonable, instrument calibration, improper use, the control valve can not meet the requirements, these problems to adjust the High Temperature Regulator parameters to improve, is clearly impossible. Such as a factory of the oxidation furnace pressure control system, set the choice of many groups of tuning parameters, and even adjust the proportion of 250%, the system still can not be stable, observed by looking for reasons, found that the valve selection problems, replace the valve , After setting the system on the normal. Tuning the High Temperature Regulator parameters is an important factor in improving the quality of control, but not the only factor. So in the event of tuning parameters can not meet the control quality requirements, or put into operation automatically very difficult. The best to calm down, carefully analyze the characteristics of the object, the composition of the system, the use of the instrument, etc., to find the problem and find out the reasons, if the system design is unreasonable, the original design of the system should be modified.

First, the plane curve and vertical curve section shall not set the High Temperature Regulator.

Second, in the middle of the bridge set two-way High Temperature Regulator, the temperature span should not exceed 200m, should be two-way spine symmetrical center set in the middle of the fixed beam above the fixed base.

Third, the High Temperature Regulator basic rail start and tip rails with the end of the joint joints from the beam joints should not be less than 2m.

Fourth, the connection line drilling position should avoid the basic rail stretching range.

5, one-way High Temperature Regulator should strengthen the sharp rail and 50 ~ 100m within the scope of rail lock, two-way High Temperature Regulator should strengthen the range of the lock range.

Sixth, the High Temperature Regulator and its front and rear line fastener type and torque should meet the design requirements. Adjuster fastener iron plate anchor bolt bolt torque of 300 ~ 350N · m; sharp rail bolt torque of 400 ~ 500N · m; basic rail support bolt torque of 300 ~ 350N · m.
