Li Hongying: to achieve perfection in the field of precision detection

 A small watch can also make a big business. A deputy manager of the metering management department of Zhejiang water supply Co. Ltd. Shaoxing Keqiao Li Hongying, 13 years of painstaking research, self pressurized, in this small area detection meter to achieve the ultimate, full participation in the water meter testing center building standard, authorization, a number of scientific research has been widely used.

　　The water meter, There is much fineness in writing　　
　　Li Hongying before a teacher, because the family mobilize work, work in 2004 came to Shaoxing Keqiao water supply company. "I am in the Department of water meter inspection department, responsible for the company's incoming water quality inspection."." Li Hongying said, when the Department has only an old master in, the work content is relatively simple, but since embarked on this post, it should sink heart to do well.　　
　　The precision table detection process, Li Hongying found large caliber water meter in error within the prescribed scope of the state, there are still a lot of room for improvement, such as water supply, water in the water flowing out of 10 tons, but the actual user water meter there may be less than 10 tons, where the middle error go? After months of tracking, Li Hongying and colleagues finally came up with scientific data and began to test the trajectory of the water meter.　　
　　"At that time, the company did not have the corresponding testing equipment, and I and colleagues to the company canteen 100 liter bucket borrowed." Li Hongying said, Master Wang and just graduated college students are also very supportive, and their three people at noon every day to the canteen of the simple shed again and again test, take apart water meter improvement, and then test...... After hundreds of tests, the water gauge error from the national standard error plus minus 2 to plus or minus 1.　　
　　In 2012, Li Jia led large-scale water meter range ratio optimization research, is widely used in the actual water meter production measurement, which is the first case in the national water company. Although the water meter error has decreased a little, but for the user, water meter readings are more accurate, but also to reflect more fair and just.　　
　　Memories of a hot day busy testing days, improved Li Hongying said, thanks to her team, Master Wang after retiring in 2006, the new six meter testing center, all the students love yourself, love many times calculation by theory, firm infected themselves have been such, although it was very difficult conditions, each test improved everyone get the sweat, big cat, but still feel very happy.　　
　　Water meters placed, have great knowledge to learn　　
　　In precision meter, there are a lot of good detection meter stacked in the warehouse every day, how to put these neat and efficient water meter display, Li Hongying started thinking.　　
　　"The shape of the water meter is not very regular, and we are thinking about how to place a water meter at the special location of the shelves." Li Hongying said, thinking of doing them first with the tape measure by the meter, this is relatively simple, but each meter placed without a certain gap, the meter will cross extension, inconvenience is not beautiful.　　
　　Li Ying and her team tried again and again, college students to calculate the relevant data, they bought their own tools, according to the data measured, welding samples. "Finally, we calculate the shelf space by averaging 7.81 millimeters, and then the spacing is separated by two bars, so that each model of water can be placed in order and orderly."." Li Hongying said, I did not expect this meter standard shelf, but also won the national patent, and widely used in the industry.　　
　　"Actually, it's not difficult to think of it now, but at that time, it was quite a sense of achievement to think of it. It was in line with my usual brain and mind." Li Hongying says.　　
　　Water meter antifreeze, very knowledgeable　　
　　Last January, Keqiao suffered 50 years of extreme cold weather, many water meters in varying degrees of frozen damage, the rate of repair in a straight line.　　
　　In addition to all kinds of tests on the meter, Li Hongying also presided over the establishment of Shaoxing Keqiao district water meter testing center, full participation in the water meter testing center building standards, authorization, editor of the quality manual and procedures, to become the only authorized local watermeterverification.　　
　　As a long time to adhere to the "water supply man" in the front line, Li Hongying broke out "small tricks" in the ordinary post". In March last year, Li Hongying to being appointed member of the Zhejiang provincial water meter Standardization Committee "; at the end of last year, Li Hongying officially named the" craftsman of Keqiao library".　　
　　"Precision watch test, although it is a small job, but I love this post, in their favorite positions constantly pressure, make the work perfect."." Li Hongying says.
