introduction：Engine cylinder block、Gearbox housing、Hydraulic cylinder and other parts are characterized by high quality，Complex shape，High cost，When it is cracked or otherwise damaged，If not repaired in time，It will destroy the entire assembly，Cause great waste。Some other parts，dowel、gear，Because the unit price is not high，When they wear out，Often replace new parts directly，In the long run，Must cost a great deal，In fact, they can be repaired and reused。 Surfacing welding is one of the surface repair techniques of parts，It is the use of manual arc welding to surfacing or repair the surface of damaged parts，Or processed by machine tools

introduction： The solidification speed of liquid die forging is fast，Therefore, the micro-segregation is lighter than other casting methods。however，The parts with deeper dents are in liquid die forging，It is easy to produce a unique macroscopic segregation - extrusion segregation。figure7-2It is used to explain the formation mechanism of extrusion segregation。Liquid metal after pouring the mold，First nucleation occurs at the mold wall，Grow up，encrusted。As the solidified layer continues to advance through the mold wall，The solute elements in the adjacent liquid phase are more and more enriched，Once the mold is pressed，This liquid will be pushed to the edges of the part。The solute element content in the segregation site is high，There are also many low-melting phases。Liquid die from steel flat flange

introduction： Adiabatic compression﹑Isobaric heating﹑Adiabatic expansion and isobaric cooling 4The process consists of a gas turbine thermodynamic cycle。There have also been gas turbines with constant volume heating cycles﹐But it is not widely used。 Cyclic process figure1 Gas turbine simple cycle(Open type) Simple cycle for gas turbine。The gas turbine draws air from the atmosphere﹐In the compressor(compressors)Intermediate compression。The compressed gas enters the gas turbine combustor﹐Fuel is added here for combustion heating。The heated high-temperature gas enters the gas turbine(Hereinafter referred to as turbine)Work by expansion。The expanded gas is discharged into the atmosphere。turbine

introduction：1）、Reducer 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。 2

introduction： Pressure filtration or vacuum evaporation－Filter unit for removing solid impurities and moisture from impure oil by pressurized filtration method。The oil filter is mainly used to improve the insulation performance of electrical oil and the purity of lubricating oil。Oil filter is divided into ordinary oil filter and vacuum oil filter two kinds。 Ordinary oil filter By the initial filter﹑Oil pump and filter device。The primary filter is a cylindrical metal mesh﹐Prevent large solid particles in the impure oil from entering the pump。The oil pump is usually a gear pump﹐Feed the impure oil into the filter。The filter device is a small hand-pressed plate and frame filter press﹐Use special filter paper as filter medium。Dont
