A technician is debugging the laser cutting machine to cut quartz pendulum.
Yan Jinkai, head of the quartz pendulum project, shows the new type of quartz pendulum.
Technician of Xingjian Special Glass Co., Ltd. in Qinhuangdao Economic and Technological Development Zone is inspecting the quartz pendulum through an amplifier.
According to Yan Jinkai, who is in charge of the project, the quartz pendulum is the core component of accelerometers for oil exploration measurement and control instruments, which was made of high-purity quartz glass of high hardness, strong rigidity, and small temperature coefficient with cold processing technology, and featured with strong impact resistance, accurate detection of displacement, and stable seismic resistance. It can be applied to the exploitation of deep wells with an underground depth of about 5,000 to 7000 meters. At present, the quartz pendulum has been put into use in oil exploration projects in Xinjiang, Shanxi, Qinghai and other provinces.
It can also be widely used in aerospace and other fields, which filled the gap in the China’s glass industry.
