When purging pipelines, what does "target plate" mean?
It is just a piece of white cloth, and dirt can be clearly seen. If there is no obvious dirt on the white cloth, it means that the pipe has been cleaned.
Another method is to use a wooden board with white paint on it and place it at the outlet of the pipe. The paint cannot dry. If there is dust on the pipe, it will stick to the paint on the board. After a period of time, paint it again. If there is no dust on the paint on the board, it is clean. hehe.
Got it, learn* Yes, haha, thank you two above
The function of target shooting is to remove impurities in the pipeline. Generally, target shooting is used to detect the cleanliness of steam lines (especially those used as power input to the unit).
Playing it is to let the debris in the pipe leave marks on the handle to calculate whether the pipe is blown out.
Generally, the target is made of aluminum plate, which is mainly used for purging steam pipelines, such as steam turbine steam lines.
study* I've heard it before but didn't understand what it meant.
By the way, how long does a period of time generally mean? Thanks
