introduction：1、What is ultrasound：Waves can be divided into three kinds，Immediate infrasound、Sonic wave、Ultrasonic wave。The frequency of infrasound is20Hzbelow；The frequency of the sound wave is20Hz~20kHz；The frequency of ultrasonic waves is20kHzabove。Infrasound and ultrasound are inaudible to the human ear。Ultrasonic due to high frequency、Short wavelength，Therefore, the direction of transmission is good、Strong penetration，This is why the design and production of ultrasonic cleaning machine reasons。 2、How does ultrasonic cleaning work Ultrasonic cleaning is the use of ultrasound in liquid socialization、Acceleration action and direct inflow

introduction：1introduction At present，The car has gone deep into the family，The safe driving of the car is related to the happiness of each family and the stability of the country，But car rear-end incidents happen from time to time，In addition, in an emergency, the accelerator was mistakenly stepped on instead of the brake, causing a car crash and death，Deeply touched our designers。with，Electronic technology, especially the development of microcontroller，MCU enters the car control system，The car has an intelligent response that can replace people in an emergency，Safer and more reliable。 Here I introduce based onMM908E624Single-chip automobile intelligent throttle。Usually the traditional throttle is mechanically operated through the right foot

introduction： Used in saturated steam turbines in water-cooled nuclear power plants to reduce steam humidity﹑A device for raising the temperature of steam。It consists of a steam separator and a reheater。In this device﹐The wet steam discharged from the high pressure cylinder of the turbine is first removed by a steam separator﹐It is then reheated to a temperature close to that of fresh steam in the reheater or at the same time with steam drawn from the high-pressure cylinder﹐Finally feed into the low pressure cylinder。The purpose of both separation and reheating is to reduce the moisture content of the steam in the low pressure cylinder﹐Avoid damaging the turbine blades and improve the internal efficiency of the turbine。The steam separator and reheater are usually combined in a large horizontal cylinder

introduction：１．Basic requirement In CNC milling processing generally do not require very complex fixtures，Only simple positioning is required、Just clamp it，The design principle is also the same as the universal milling machine fixture，Combined with the characteristics of CNC milling，Here are some basic requirements： ．In order to ensure that the workpiece in this process to complete all the surface to be fully exposed，The fixture should be made as open as possible，Because a certain safe distance should be maintained between the clamping mechanism element and the machining surface，At the same time, the clamping mechanism components are required to be low，To prevent fixture with milling machine spindle sleeve or cutter sleeve、The cutting tool interferes in the machining process。
