Jingwei Technology DDL-1 Air Slurry Meter Accepted by China Earthquake Administration

[China Instrument Network Instrument R&D] On December 20th, the 2017 Seismic Precursor Network Equipment and Equipment Update Project acceptance meeting led by the China Seismological Network Center was held in Beijing. Among them, the participating experts discussed the performance and function of the DDL-1 measuring instrument developed by Zhengzhou Jingwei Science and Technology Co., Ltd., as well as the report on the running test of the station environment and the results of the test run. They agreed that the instrument passed the acceptance and was incorporated into the national earthquake. The precursor network.

To ensure the quality of the instrument, according to the requirements of the China Seismological Network Center, Zhengzhou Jingwei Technology Company sent the DDL-1 pneumatic pick instrument to the National Level One Special Measurement Laboratory at Nanhua University on August 14th. The instrument was accurately calibrated, and various indicators were rigorously tested. On August 28th, Jiujiang's "Jianjing Observation Instrument Test Platform" of the Seismological Bureau of Jiangxi Province completed the instrument performance index review and function test. To further ensure that the instrument testing process is rigorous and objective, from August 28 to November 13, eight DDL-1 pneumatic pick instruments were divided into four groups. At the same time, they were at the Jiujiang Seismic Station in Jiangxi Province, Liaocheng Earthquake Station in Shandong Province, and Anhui Province. At the Minjiang Seismic Station, a 2-month on-site comparative observation was carried out to effectively test the instrument's stability, consistency, and various functional indicators in the actual environment. On November 17, an expert group of China Earthquake Administration conducted a review of the test report and test results. Through analysis and discussion, it was concluded that the test procedures and results described in the test report were detailed and objective, and that the instrument's function indexes, performance indicators, and instrument stability were stable. Sex and consistency are good, in line with the observation requirements of the seismic station on the radon instrument. On Dec. 20th, the China Seismological Network Center in Beijing held the 2017 Earthquake Precursor Network Equipment and Equipment Upgrading and Upgrade Project acceptance meeting held in Beijing. The final acceptance of the DDL-1 type pneumatic pick instruments and other equipment was carried out.

At present, more than 20 seismic stations across the country have used this ionization method to perform precursory observations. The successful acceptance of the DDL-1 air trapping instrument was incorporated into the National Earthquake Precursor Network. This is another breakthrough for the instrument in the field of technology following the provincial and ministerial achievement appraisal in 2015. It provides a new observation method for China's earthquake precursory observation hydrochemistry department, which is of great significance for improving the earthquake monitoring and forecasting work.
