  • The purchase of semiconductor refrigeration

    introduction:Semiconductor cooler in the case of power,The two plates will produce a certain temperature difference,It is its condensing surface that people useCPUProvide a low temperature environment。However, most of the refrigeration tablets sold on the market are industrial supplies,Not specifically for computersCPUDesigned to dissipate heat。Such products generally consume more power,The power consumption of smaller industrial refrigeration tablets commonly found on the market is12V3A,There are usually only two power leads and no plastic card connector for the computer,Cooling is very effective,Be used on...CPUMore than enough。But pay attention to whether your power supply is affordable when using it。 though

  • Homogenization mechanism of high shear homogenizer

    introduction:mixing、sterilize、Homogenization is an essential step in cold beverage production。According to the traditional production process,The above link allows mixing cylinder、Hot and cold cylinder、High pressure homogenizer three equipment to complete,And need to be equipped with pipes、valve、Pumps and other accessories,Cumbersome production process。among,High pressure homogenizers have many unavoidable disadvantages:Homogenizing valve、Seals wear out very easily,A short life span,It is usually used for only about three months,Shorter life of spring parts,Need frequent replacement。 Working principle of high shear homogenizer High shear homogenizer structure consists of stator、Rotor composition。The stator is composed of several rings of teeth,Its principle of action is high-speed rotation

  • Hydraulic transmission

    introduction:Using liquid as the working medium,A fluid drive that relies on the hydrodynamic action between the impeller and the liquid to transfer energy。The impeller will power the machine(Internal combustion engine、motor、turbine)Input speed、Torque conversion,The working part of the machine is driven by the output shaft。The liquid is loaded with the input shaft、Output shaft、The impellers on the shell interact,Produces a change in the moment of momentum,Thus achieving the purpose of transferring energy。Hydraulic transmission and hydraulic transmission by liquid pressure energy to transfer energy in principle、There are great differences in structure and performance。The input shaft and output shaft of the hydraulic transmission are only connected by the liquid as the working medium,No direct contact between components
