introduction： 1、When the magnetic powder brake and clutch are used as winding、Roll out the time of continuous sliding，Product and life depend on conditions of use(relative Sliding speed etc)There are differences between different and different。But generally speaking，The life of iron powder in the stop current when the stop torque is reduced is about4500～7500Hour (s)。however，In some cases it is not available Below freeze-frame torque，Therefore, it can continue to use，Life expectancy can be extended even further。merely，Even with the same sliding working rate，Sliding rotation velocity、That is, the relative rotation speed is continuously at a relatively high speed When in a high state，Life expectancy tends to decrease，Therefore,

introduction：1Reducer heat and oil leakage。Worm gear reducer to lift rate，Generally, non-ferrous metal is used as worm gear，The worm is made of harder steel，Because it is sliding friction drive，During operation，It generates a higher amount of heat，The thermal expansion of the reducer parts and seals is different，Thus, gaps are generated on the mating surfaces，The oil becomes thinner as the temperature increases，Easy to leak。There are four main reasons，One is whether the material collocation is reasonable，The second is the surface quality of the meshing friction surface，The third is the choice of lubricating oil，Whether the amount added is correct，The fourth is the assembly quality and the use environment。 2Worm-gear wear。Wormwheel general

introduction：A boiler that supplies steam to the steam-powered machinery that propels ships。The difference between Marine boiler and land boiler is﹐Matching contour﹑There are strict limits on size and weight。Such as﹐On a warship, it is better to sacrifice the thermal efficiency of the boiler than to install an air preheater﹐Not even a economizer。structurally﹐The boiler should be able to adapt to the sway of the ship﹑Navigation conditions such as roll and impact。Marine boilers must have a certain amount of steam﹑Water storage capacity﹐To meet the needs of steam power machinery frequent and large changes in load。In order to meet the requirements of light and high mobility﹐Heavy oil is widely used。Boiler evaporation capacity is10～200Tons of/when﹐Steam parameters are slightly lower

introduction： Spring-operated needle nozzles do not require hydraulic or pneumatic external drives，Instead, the injection pressure and spring elasticity are used to realize the automatic opening and closing of the nozzle，The reliability of its operation is based on the high precision matching between the needle valve and the diverter shuttle。therefore，It not only has high precision、Advantages of high reliability，And it is easy to load and unload on the mold。 Hot runner casting system, that is, no runner casting system, refers to the product after stripping only the product itself without the casting system solidifying material，A mold with such a pouring system is called a hot runner system。In a hot runner system，There are two forms of pouring mouth：open
