New products--Fatigue Testing Machine
Fatigue testing machine has simple structure, convenient operation, high efficiency, low energy consumption and other characteristics, therefore it widely is used in the field of military scientific research, colleges and universities and industrial production. High-frequency fatigue testing machine is widely used for testing properties of anti-fatigue crack, testing KIC value, S-N curve and so on; it is used for testing fatigue lifetime of all kinds of parts (e.g. plate gear, crank, bolt, chain, connecting rod, compact tension and so on) with various fixtures.
It may complete the symmetrical fatigue test, the asymmetrical fatigue test, the unidirectional pulsation fatigue test, the block spectrum fatigue test, the modulation fatigue test, the fatigue test at high and low temperature, three point bending, four point bending, torsion fatigue tests and so on. At present colleges and universities, research department and industrial and mining enterprises use the high frequency testing machine to carry on fracture toughness test and testing metallic material crack growth rate and limited value of martial. With the development of microelectronic technology and computer technology, as well as perfect test method, its use function is increasing expansion.
Ventilation pipes are usually used to transport gas. This is a municipal infrastructure, mainly to make air circulation and reduce the concentration of harmful gases.
It is mainly used in industrial and construction projects, including the cleaning system of the dust free workshop in the electronic industry, the medical aseptic workshop, the food purification system, the hotel, the central air conditioning system of the shopping mall and so on. Hospitals, factories and offices; exhaust pipes for industrial pollution control; industrial environmental ventilation ducts, gas drainage systems and cyclic climate controlled air systems.
