[summarize] With the increasing awareness of environmental protection and health,The application of powder products has attracted more and more users attention。In Europe and the United States economically developed countries,The use of many chemicals, especially toxic chemicals, requires granulation;At home,Many enterprises for export,Part of the powder product is granulated,To meet the needs of foreign investors。With Chinas accession to the World Trade Organization(WTO),China will gradually integrate with the international community in various fields,The chemical industry is certainly no exception,Therefore, the granulation of powder products will become more and more important。GZLSeries dry powder granulator is our company according to user needs,In the absorbing countries
First check whether the two cycloidal wheels are a pair.Cycloidal wheels are manufactured in pairs.That is to say, the two pieces of the cycloidal wheel are not separated during the production process.At installation.The concept of a pair is that two cycloidal wheels can be fully colocated.Clad 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。]hole,decapore(Shaft pin hole)Complete at the same time as the external tooth type
erosion A wear on the surface of a part caused by the impact of fluid containing solid particles。For example, the impact plate of the fan coal mill and the blades of the water turbine will suffer erosion。With the high speed of machinery and the wide application of materials with high strength to weight ratio﹐Erosion is a growing concern。When solid particles impact the surface﹐The wear rate is related to the impact Angle。For plastic materials﹐When the impact Angle is approx30°when﹐The wear is mainly caused by cutting and furrowing﹔On the verge of90°Fatigue plays a major role。Brittle materials may produce brittle fracture failure under the impact force of solid particles。High velocity fluid impact﹐Even without
The first is to lubricate the 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。]Parts of,Reduced 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
1、Soaking method:NSKbearing[NSKbearing:Seiko Co., LTD(NSK LTD.)Be established in1916years,It is the first manufacturer to design and produce bearings in Japan。NSKThe function of the bearing fit is to makeNSKThe stationary ring and rotating ring of the bearing are respectively the stationary part of the installation part(Usually a bearing seat)And rotating part(Usually an axis)Solidify together,Thus, the basic tasks of transferring the load in the rotating state and defining the position of the moving system relative to the stationary system are realized。]It is soaked in rust-proof grease,A method of affixing a layer of anti-rust grease to its surface。Oil film thickness can be controlled
Standard horizontal mounting is the easiest way to assemble。Maintains high precision and accuracy when subjected to shock and vibration。And easy to install,It is easy to disassemble the equipment and the silver guide rail,distinct,maintenance。
A sensor based on the principle that the resistance value of a metal or semiconductor varies with temperature﹐It is a temperature measuring component commonly used in temperature measuring instruments。The resistance value of metal thermal resistance increases with the increase of temperature﹐Platinum thermal resistance is commonly used(The temperature measurement range is-200~+850℃)﹑Copper thermistor(-50~+150℃)And nickel thermal resistance(-60~+180℃)3Kind of。Thermal resistance is mostly used in diameter 0.04~0.1Millimeter of pure wire wrapped in sheets or rods of mica﹑glass﹑Ceramic or bakelite
1.Precision 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。]Requirements for matching parts Due to precision 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
first,FAGDeep groove ball 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。]Whether the installation is correct,Directly related to the 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 phase each other on the shaft
For heavy loads,It should usually be tighter than the fit in light loads and normal loads。Heavier load,The greater the fit interference should be。 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。]Device of、Disassembly method,Be based onSKFbearing[SKFbearing:SKFThe full name is“Svenska Kullager
