introduction：Ningbo stainless steel： Stainless steel plate is generally a general term for stainless steel plate and acid-resistant steel plate。Stainless steel plate refers to atmospheric resistance、Steel plate corroded by weak media such as steam and water，The acid-resistant steel plate refers to acid resistance、alkali、Steel plate corroded by chemical etched media such as salt。Stainless steel plate since the beginning of this century，The development of stainless steel plate has laid an important material and technological foundation for the development of modern industry and scientific and technological progress。Stainless steel plate There are many kinds of steel plates，Different performance，It has gradually formed several categories in the process of development。According to the structure is divided into austenitic stainless steel plate、Markov stainless steel plate（Includes precipitation-hardened stainless steel plates）、Ferritic stainless steel plate、And austenitic ferritic duplex stainless steel plate and other

introduction：The inverter power supply is the alternating current in the mains power throughAC→DC→ACtransform， The output is pure sine wave，Output frequency and voltage Adjustable within a certain range。It is different from the variable frequency speed controller used for motor speed regulation，It is also different from ordinary AC power supply。The ideal AC power supply is characterized by frequency stability、Voltage stabilization、The internal resistance is zero、The voltage waveform is pure sine wave（distortionless）。The variable frequency power supply is very close to the ideal AC power supply，therefore，More and more advanced developed countries use variable frequency power supply as a standard power supply，In order to provide the best power supply environment for electrical appliances，It is convenient to objectively evaluate the technical performance of electrical appliances。 There are two main types of inverter power supplies：Linear amplifying sumSPWMOn-off type。 To long life of inverter power supply，Daily maint
