This kind of equipment gives expression to developmental level, direction, and regulative aim and future potential that embodies product structure of Lanzhou vacuum. We have vacuum argon arc welding machine in use for noble metal and nonmetal of ceramics. We also have strong neutron generator that serve ion accelerator, drum vacuum drier series that serve medicament, plastic and metallurgy industry. We still have vacuum freeze-dry serials of equipments in use for biological pharmacy and green-food, and vacuum pressure dipping serials of equipments in use for electric power, electrical engineering, transformer of engine industry, electrical machinery eliminating gas, dryness and new insulated technics, and their application fields rapidly widen to timber consolidating dipping, refractory compactness dipping again lately. Refractory dipping gives play to important effect for improving age of metallurgy furnace. We have life assurance, experimental module for space suit, temperature and humidity experimental module, the orbital module and the re-entry module for training cosmonauts, demonstrating module of integrative performance, pose adjusting simulative module of rocket in use for spaceflight payload plane. Provided with large-size whole set morphia vacuum extraction equipment in use for special type pharmacy, and vacuum fresh preservation and air adjusting equipment such as fruit, medicinal materials, food supplies and so on in use for green food engineering.
