Nuclear power fire alarm equipment passed the seismic test
Recently, Xi'an Nuclear Instrument Factory developed Fuqing, Fang Shan, Hainan Changjiang Nuclear Electric drive fire alarm control system equipment, laboratory construction in Xi'an University of Architecture and Technology passed the seismic tests. The test results show that the prototype nuclear fire alarm equipment after the completion of the provisions of the earthquake test, the prototype structure and performance remain intact, fully meet the requirements of the nuclear power plant fire alarm control system. The experiment based on "fire alarm control system seismic test program" and "HAFJ0053 seismic equipment test guide". The experts conducted tests on the structure, performance and performance of the equipment before, during and after the test. The values ​​of the parameters were all within the specified limits and met the seismic requirements. The test was successful. As early as in 2008, Xi'an Nuclear Instrument Factory successfully developed the first set of fire alarm control and linkage system for nuclear power stations, filling in the domestic blank. In recent years, the plant product design and manufacturing and engineering services capabilities has always been in the industry-leading position, for a number of nuclear power projects to provide complete sets of fire alarm equipment, is the largest and only to meet the second and third generation nuclear power technology requirements of fire alarm control system supplier.
Aluminum Polishing Sheet is a special Aluminum Sheet.Its surface has been polished hence gives good performance in surface condition.The advantage of aluminum sheet is as follows:
1. Easy to process.
Aluminum Panel Sheet,Polished Aluminum Sheet,Polished Aluminium Sheet,Aluminium Profile Sheet Trumony Aluminum Limited , https://www.szaluminumcoil.com
The results show that the casting aluminum alloy with good casting property or deformation aluminum alloy with good processing plasticity can be obtained by adding certain Ba Au Du element.
2. Good conductivity and thermal conductivity.
The electrical and thermal conductivity of aluminum is second only to silver, copper and gold.
3. The density is small.
The density of aluminum and aluminum alloy is close to 2.7 g / about 1 / 3 of that of iron or copper.
4. High strength.
The strength of aluminum and aluminum alloy is high. The matrix strength can be strengthened by cold working to a certain extent, and some brands of aluminum alloy can also be strengthened by heat treatment.
5. Good corrosion resistance.
The surface of aluminum is easy to produce a dense and firm protective film of Al2O3, which can protect the substrate from corrosion.
