introduction:Basic concept of stainless steel: Stainless steel is short for stainless steel,It is composed of stainless steel and acid-resistant steel two parts,In short,Steel that can resist atmospheric corrosion is called stainless steel,The steel that can resist the corrosion of chemical media is called acid-resistant steel。Generally speaking,Body countWcrGreater than12The steel has the characteristics of stainless steel according to the microstructure after heat treatment can be divided into five categories:Ferritic stainless steel、Martensitic stainless steel、Austenitic stainless steel、austenite-Ferritic stainless steel and precipitated carbonized stainless steel。 Ferroalloy is an important raw material for steelmaking and casting,Used as a deoxidizer in steelmaking and casting

introduction:Why does stainless steel also have magnetic? It is often thought that magnets attract stainless steel,Verify its advantages and disadvantages and authenticity,No magnet, no magnet,Think well of,The real deal;The smoker is magnetic,They think its a fake。In fact,This is an extremely one-sided approach、Unpractical ways of identifying errors。 There are many kinds of stainless steel,It can be divided into several categories according to the organizational structure at room temperature: 1.Austenitic type:Such as304、321、316、310Etc.; 2.Martensitic or ferritic form:Such as430、420、410Etc.; Austenotype is non-magnetic or weakly magnetic,

introduction:Secure a ferrule,The maximum amount of movement of the other ring along the radial or axial direction。The maximum amount of movement along the radial direction is called radial clearance,The maximum amount of movement along the axis is called axial clearance。 Generally speaking,The greater the radial clearance,The axial clearance is also larger,Vice versa。Per bearing[bearing:bearing(“Bearing”,Japanese person“Axial receptor”)It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said,When other parts move relative to each other on the shaft,A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]The state youre in,Wide clearance

introduction:To control mechanical noise and vibration,First, it is necessary to identify where the vibration or noise is generated,The commonly used identification methods are mainly: (1)Subjective identification,Use the ear to determine the source of mechanical noise and its primary and secondary,Because the human ear brain system itself is a very sensitive sensory system,So it can correctly distinguish between different sounds.The result of this judgment,Can do a general understanding of noise source location。 (2)Step by step operation method,For complex machinery,Some components can be disconnected step by step,To distinguish the impact of each part of the noise on the whole machine noise。 (3)Selective isolation,Cover the parts of the machine
