introduction： Change the quality、The law of conservation of momentum and energy is used to correlate fluid velocities obtained from fluid motion、stress、The relationship between physical quantities such as density and temperature。The basic equations of fluid dynamics can be established for both the system and the control body。A system is a combination of fixed substances；The control body is a fixed volume of space relative to a certain coordinate system，Its boundary surface is called the control surface。Most of the basic equations discussed in fluid dynamics are established for control bodies。The basic equation has two forms: integral and differential。The former obtains the fluid by integrating the control body and the control surface

introduction：In daily useIKObearing[IKObearing:IKONeedle roller bearing with its special internal structure to achieve the mechanical design of small、Light weight。Guideway bearings are based on the high quality given by needle roller bearings，Precision machining with unique mechanical equipment，Evaluate the quality of the latest machines，Products always maintain high performance and high quality level。]In the process of，The clearance between the bearing and the shaft must be suitable。So how to test whether the combination of imported bearings and shafts is suitable？Now let me introduce it briefly。 The radial clearance can be detected by the following methods。 1、Measuring tape method For diameters

introduction： So-called gas lubricated bearings[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。]Refers to the use of gas lubricants for lubrication of interactive bearings，Our common gaseous lubricant is air。In use，The mechanism of gas lubricated bearings forming bearing gas film is the same as that of liquid lubricated bearings。therefore，Gas lubricated bearings have the following when used

introduction： Centrifugal separator for separating components in suspension by centrifugal filtration。There are many holes in the drum wall of the filter centrifuge﹐The inner surface of the drum is covered with filter media。The suspension added to the drum rotates with the drum to produce a huge centrifugal pressure﹐Under the action of pressure, the liquid in the suspension is thrown out through the filter medium and the holes in the drum wall﹐Solids are trapped on the surface of the filter medium﹐Thus, the separation of solid and liquid is realized。The centrifugal force generated by the suspension in the drum is thousands of times the force of gravity﹐The filtration process is enhanced﹐Speed up filtration﹐The filter slag with lower moisture content was obtained。Solid particles greater than0.01Millimeters of suspension generally can

introduction：Before it was put into operation，Fill the reducer with the recommended type and value of grease。The reducer is lubricated with lubricating oil。For vertical mounted reducer，Whereas lubricating oil may not guarantee the top 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。]Reliable lubrication，Therefore, additional lubrication measures are used。 in

introduction：summarize So-called vacuum drying，That is, the material to be dried is placed under vacuum conditions，Heat dry，It is the use of vacuum pump for pumping air to dehumidify，Create a vacuum in the working room，The drying rate is accelerated。 Vacuum drying theory shows 1、The boiling point of the solvent or water in the material is reduced under vacuum conditions，The heat transfer driving force of the evaporator is increased，So constant heat transfer In terms of，It can save the heat transfer area of the evaporator。 2、The heat source of evaporation can be low-pressure steam or waste heat steam；（Special requirements can be heated with water or oil，The factory can be customized for you Door design

introduction：Pursue high added value with multiple varieties and small batches Shift production to Asia、Eastern Europe、The hollowing out of manufacturing in South America，Not only Japan，Now it has become a common phenomenon in many so-called advanced industrial countries。 Take Japans machining industry, for example，There is an obvious shift of mass production to China，What is maintained in domestic production is only multi-variety and small-batch products with high added value。In other words，If it can not be produced in a short time rate, the processing precision is high、Complex small batch products，Its hard to survive at home。Can also be said：“As long as China can produce even day

introduction：After the vehicle has been driving for a long time, whether it feels that the car will be accompanied by left or right after driving in a straight line、The body will have the floating pole tire has the phenomenon of unilateral wear？If so，Then your car may have to do a positioning。Why does this phenomenon occur and what to do to locate it？ In fact, it is mainly because the vehicle is often subjected to a lot of bumpy road surface、Hole and water hole cover impact and chassis parts wear and other reasons，Under prolonged vibration and shaking, the mechanical position of the suspension and tire set by the original factory will be changed，When the Angle runs away，Thats what happens。
