introduction：1．At present, there are many companies abroad to promoteSMSequipment，But the price difference is huge。Price is an important consideration when purchasing equipment，But at the same time considering the price，The more important point is to consider the performance of the device。SMSThe reason why it is popular in the market is mainly in the performance of the general spunbonded cloth can not replace the function。Such as：SMSCapable of certain hydrostatic pressure，It shields urine and blood to some extent。therefore，When considering the model choice，We have to consider the price，Performance is more important。 2．Attention should be paid to the melt-blown layer：inSMSIn the，MRepresents the melt-blown layer。The melt-blown layer is very important to withstand hydrostatic pressure

introduction： introduction Steam turbines have many large shaft classes、Plates and cylinder parts(As principal axis、rotor、impeller、septum、cylinder)Need to be turned，The turning process is divided into rough、semigrance(trundle)washi。Large margin when roughing，Turning tools need to withstand a lot of cutting resistance，It is also required that the blade can maintain sufficient strength and not produce displacement under the condition of strong cutting，And finishing is the key of parts processing，It is the guarantee of processing quality(precision、roughness、Form and position tolerance, etc)，Therefore, it is required that the spatial position of the tool blade cannot be changed during use。

introduction：1、Function and classification of lubricants The application of paper coating lubricants dates back to the beginning of this century。At that time, the paper pigment coating adhesive was mainly animal glue or casein，The paint has a very low solid content。These adhesives have good adhesion and excellent water retention properties，But the membrane it forms is brittle，Therefore, it is necessary to add an additive that can improve the folding and bending resistance of coated paper and board。These additives also improve the fluidity and equalization of wet coatings。This is effective for both wet paint，An additive that also plays a role in dry coating，It was once seen as“plasticizer”Additive to，ready-to-use

introduction： As shown in the figure,The speed regulating valve is a throttle valve with pressure compensation。It has a constant difference pressure reducing valve and a throttle valve in series。Throttle before、afterpressurep2andp3Lead to pressure reducing valve spool right respectively、Both left ends，On-load pressurep3magnify，Therefore, the liquid pressure acting on the left end of the pressure reducing valve core increases，Move spool to the right，Pressure opening extension，Pressure drop reduction，makep2Also increase，So that the throttle valve pressure difference（p2-p3）Remain unchanged；Vice versa。In this way, the flow rate of the speed control valve is constant（Not affected by the load）。 The speed regulating valve is the structure of reducing pressure before throttling。Can also be designed first

introduction： Use heat-absorbing media to cool high temperature parts﹐A device to keep the internal combustion engine operating at optimum temperature。In the internal combustion engine﹐Due to cylinder liner﹑Cylinder head﹑Piston and valve and other parts are directly in contact with high temperature gas and are heated strongly﹐The machine temperature is very high。This will not only lead to a reduction in the strength of the parts﹐And it can generate a lot of thermal stress﹐Cause damage to the parts。High temperatures can also damage the lubricating film on the cylinder wall﹐Oxidize and deteriorate the lubricating oil﹐Resulting piston﹑The piston ring and cylinder liner are badly worn﹑Bite or stick。In addition﹐Too high a temperature will also reduce the density of air entering the cylinder﹐knock﹑Abnormal combustion such as premature combustion。
