introduction：Ceramic ball bearings are not only beautiful in appearance，It has several advantages at the same time： one、High speed of revolution：The ceramic ball has oil-free self-lubricating properties,The friction coefficient of ceramic ball is small,Therefore, ceramic ball bearings have a high speed.According to statistics, the bearing using ceramic ball is the speed of the general bearing1.5Times more rotational speed. two、High temperature resistance：The thermal expansion coefficient of ceramic ball is small,In the high temperature environment will not cause the bearing ball to expand due to temperature,This greatly improves the service temperature of the entire bearing,The temperature of ordinary bearings in160Degree or so,Ceramic balls can be reached220Degree or above. three、Long life：Ceramic balls can be made without any grease,Which means even if the grease dries out,The bearings are still operational,In this way, the occurrence of premature bearing damage caused by grease drying in ordinary bearings is avoided.A

introduction：Electric slide in the installation and operation process，It depends on proper use，The performance of the electric slide can be maintained，Avoid damage or shortened life of electric slide due to improper installation。 1、Electric slide in the installation and operation process，Possible problem points，Summarise as follows： (1)、The flatness of the bottom surface of the electric slide mounting is not up to standard。 The bottom surface of the electric slide is too large，It will cause the bottom surface of the electric slide to be forcibly locked，Cause the underside of the platform to slide，The linear guide rail and ball screw have strong bending deformation。Light will increase the operating resistance of the electric slide，It is possible that the electric slide can not run，Dramatically shorten the life of the electric slide。 According to the accuracy level of the electric slide，General ordinary grade on the installation of the bottom surface flatness requirements should be less than0.05mm/m。For precision grade，The

introduction：1 Selection of circuits and devices One key point is retentiondv/dtanddi/dtAt a lower level,There are many circuits through reductiondv/dtand/ordi/dtTo reduce radiation，This also relieves the pressure on the switch tube，These circuits includeZVS(Zero voltage switch)、ZCS(Zero current switch)、Resonance mode.(ZCSA kind of)、SEPIC(Single-ended primary inductor converter)、CK(A set of magnetic structures，Named after its inventor)Etc.。 Reducing the switching time does not necessarily lead to an increase in efficiency，Because of the magnetic elementRFOscillations require buffering with strong losses，Eventually, a diminishing return journey can be observed。Using soft switching technology，Its a little less efficient，But in savings Eigensum filtering/Shielding has even greater benefits in terms of space taken up。
