(one)summarize With the development of our economy,More attention is paid to environmental protection,For the brewing industry,Slaughtering industry,High moisture organic waste from aquaculture,Especially slag waste,More and more attention is paid to the disposal of livestock manure;On the other hand,With the increase of population,grain,Fertilizer feed is in short supply。Will livestock manure,The wet residue is utilized,That can solve the fertilizer,The shortage of feed,It is a great event that benefits the country and the people。 two)The composition and working principle of the equipment AType d equipment 1、Working principle:&nb

As the worlds 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。]SKFbearing[SKFbearing:SKFThe full name is“Svenska Kullager-Fabriken”The Chinese transliterated name is“SKF”;SKFThe group is headquartered in Gothenburg, Sweden,Is a leader in bearing technology and manufacturing
Different lubricants are prohibited from mixing with each other。Oil level plug、The location of the drain plug and ventilator is determined by the installation position。Their relevant locations are available for reference Reduction gear Reducer installation position diagram to determine。 Check the oil level Cut off the power,Protection against electric shock!Wait for the reducer to cool! Remove the oil level plug to check if the oil is full。 Install the oil level plug。 Inspection of oil Cut off the power,Protection against electric shock!Wait for the reducer to cool! Open the oil plug,Oil sampling。 Check the viscosity index of oil If the oil is noticeably cloudy,Recommend replacement as soon as possible。 For speed reducer with oil level plug
1Hydraulic system cleaning significance[1]From the point of view of use,The first condition for the normal operation of the hydraulic system is that the inside of the system must be clean。Before the new equipment is operational,Or after an overhaul of a piece of equipment,Contamination of the hydraulic system is inevitable,Although manufacturers of hydraulic components pay great attention to the internal cleaning of the components themselves,But new components can still contain burrs、cuttings、flash、dirt、Contaminants such as welding slag and paint。Components can also be due to poor storage、Transport and cause pollution。During the making of the tank,Possible accumulation of rust、Paint chips and dust, etc,Although the tank is cleaned before use,But a lot of dirt
Angular contact 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。] *There is a contact Angle between the ring and the ball,The standard contact Angle is15°、30°and40° *The greater the contact Angle, the greater the axial load capacity *The smaller the contact Angle, the better the high-speed rotation
Timken 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。]Imported bearing[Imported bearing:Simply put, the import bearing agent refers to the sale of an imported bearing brand。The main brands of imported bearings arenskbearing,ikobearing,fagbearing,Of good quality,Of course, the price is not cheap。]In the precision parts,bearing
1、Install coupling on output shaft of cycloidal reducer、Belt pulley、Direct hammering is not allowed when connecting parts such as sprockets,Because the output shaft structure of the reducer can not withstand the axial pounding force,The coupling can be pressed into the shaft end screw hole。 2、Axle diameter selection of output shaft and input shaftGB1568-79cooperate。 3、The lifting ring screws on the reducer are only used for lifting the reducer。 4、Install the reducer on the foundation,The mounting center line mark of the reducer should be calibrated
