Question 1: How to determine the overhaul and repair inspection unit safety valve strength and technology? Answer A: There must be a strong professional team, because any maintenance and calibration work by engineers to implement. B: Have a professional maintenance tools and calibration equipment. C: good service and positive attitude. D: rich industry experience, you need to understand the various manufacturers of products. Question 2: How to determine the quality and effectiveness of the operation after the overhaul and calibration? Answer: There are a lot of people think it is qualified if the valve does not leak after overhauling and checking. In fact, this is a basic requirement. Is the main safety valve can move within the standard range, after the action back to the seat? Back to the seat pressure can be within the eligibility range? Is there a possibility of jam astringent? Will happen frequency hopping possible? Because the safety valve once the frequency hopping, the consequences will be more serious, if it is the frequency of safety valve on the boiler body, if serious, was forced to stop the furnace shutdown, and even the steam inside the boiler exhaust. If the company can do this, it can be said that his overhaul and verification technology is very strong. Question 3: Safety valve in the unit operation, how to ensure safety under the premise of maximizing the economy? Answer: For example: The following table is the safety valve of the boiler configuration of the 300,000 Wuhan boiler plant No. Installation location Model Design pressure Actual set pressure Remarks 1 Steam drum 1 1749WB 19.81 19.81② To design pressure deviation setting Pressure 2 Steam drum 2 1749WB 20.19 20.19 → Normal setting 3 Steam drum 3 1749WB 20.38 20.38↘ Deviation set pressure to design pressure 4 Superheater 1 1730WE 18.73 18.73↘ Deviation set pressure to design pressure 5 Superheater 2 1730WE 18.38 18.38 ↗ to the design pressure on the set pressure deviation According to most people practice, the actual set pressure closer to the design pressure better or disorderly set the pressure ± 1%. As professionals are generally set in accordance with the above table to set the pressure of this set has the biggest advantage is both to ensure safety and economic. The reason is: superheater 2 safety valve is the easiest action, it is more likely to leak, once the valve will leak ahead of action, so it will have a great impact on the unit. Superheater 1 safety valve in the pressure continues to rise when the rapid action will be, as soon as possible pressure relief. If the pressure continues to rise to the pressure of the steam valve when the safety valve action, you can let it act as late as possible, after all, the more the safety valve the greater the risk of action, but if the pressure can not control the rise, you can allow the other two safety valve One after another action, when all the safety valve is opened, it can reach 1.03 times the boiler rated evaporation, can play a role in safety protection. Reheater system safety valve settings as well. This setting is also a combination of the experience and operation of the needs of the sum of the results. Of course, this setting should also consider the safety valve action on the drum water level. Question 4: How to ensure safety valve does not leak when running? Answer: A: The valve should be disassembled and repaired before each calibration to remove rust, fly ash, dust and other impurities in the valve body, nozzles and related parts. B: grinding surface finish and flatness to achieve the standard. C: spool step can not be lower than the manufacturer's minimum requirements, otherwise the spool seal will be reduced. D: valve seat height can not be less than the minimum requirements of the manufacturers, below the minimum requirements, you need to use special tools turning plastic surgery. Question 5: Why some safety valve seat cracks will appear? Answer: The main reason for the seat cracks may be for the following reasons: A: the quality of the seat itself B: seat step is too low, or no step, the seat width has been approximately doubled, both inside and outside the seat absolute The temperature difference will increase, thermal stress will increase accordingly. This is one of the main reasons why the seat step below the manufacturer's minimum requirement is turning. C: When the valve seat is low and moving, the temperature of the outer wall of the valve seat rapidly increases, and the thermal stress changes greatly. D: As the valve seat is the lowest mechanical strength of the valve at the stage, the over-pressure test is easy to produce cracks on the seat have an impact. E: Seat overlay on the valve seat material and the impact of crystal structure, almost all foreign brands (dresser \ crosby \ bopp & reuther) safety valve seat is not surfacing.
