Apply: Widely used in pharmaceutical、Chemical engineering、food、Textile printing and dyeing、Grain processing、Wood processing、Drying of various products in automotive and other industrial fields、Curing heat setting and other functions。 principle: The fuel is burned through a burner,High temperature flue gas generation,The heat of the high temperature flue gas is transferred to the heated air by means of a hot blast stove with enhanced heat transfer measures,The temperature of high temperature gas decreases to250℃The following is discharged to the atmosphere by the induced draft fan,After absorbing heat, the temperature rises to the rated value and is sent out through the hot air outlet,When the observed temperature reaches the upper limit of the rated temperature,The burner will automatically stop burning
introduction With the development of the global economy,The new technological revolution continues to make new progress and breakthroughs,The rapid development of technology has become an important factor in promoting world economic growth。The continuous development of market economy,Promote industrial products to more and more varieties、In small quantities、High quality、The direction of low-cost development,In order to maintain and strengthen the competitiveness of products in the market,Product development cycle、Production cycles are getting shorter,So the key process equipment for manufacturing various products—Mold requirements are becoming more and more demanding。 On the one hand, enterprises pursue economies of scale,Make the mold to speed up、precision、Long-life formula
one、Tapered roller thrust 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。]The structure of、Performance characteristics Tapered roller bearings due to thrust[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
Most private machinery enterprises enter the market at a low price,It seems to have become routine。However, if it is considered that private machinery enterprises ignore the rules of the game of market competition,Is unfair。In all fairness,They did what they had to do。Seven or eight years ago or earlier debut of private machinery enterprises,At the beginning,That is, not occupying the time,It doesnt take any land,Curl up in a not yet loose policy environment,And encountered the oppression of different economic types of enterprises,We have to make the most of the advantages of low costs,To attack the weaknesses of other economic types of enterprises, especially state-owned enterprises
KOYOBearings are the main components of a locomotive,Especially traction motors、Journal boxKOYObearing,Its function plays an important role in safe transportation,When the locomotive is running on line,In a dayKOYOBearing failure,It will take the entire train out of service,Blocking the main transport line,In particular, passenger trains broke down,The negative impact is even greater,Simultaneous locomotiveKOYObearing[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 are opposite each other on the shaft
The manual sludge discharge of pulse clarifier is not timely,The normal operation of the clarifier is affected,In view of the problem combined with the actual,The water plant adopts automatic control sludge discharge technology。Monitor the mainframe in the automatic control system of the pulse clarifier、Communication network、PLCAnd application software to realize reliability technology design,Two methods of regular discharge and automatic discharge are realized。 keyword:waterworks;Computer application;Settling basin Chinese library classification number:TU991.62 Document identification code:B Article number:1009—2455(200
Ensuring a smooth start is the primary function of the clutch。Before the car started,Naturally, you start the engine first。And when the car starts,The car accelerated gradually from a complete standstill。If drive train(It connects the whole car)Rigidly connected to the engine,Once the transmission is in gear,The car will make a sudden leap forward,But it doesnt get started。This is because the car goes from standstill to forward thrust,It has a lot of inertia,It creates a large drag moment on the engine。Under this inertial resistance moment,The engine speed drops sharply to the lowest stable speed in an instant(normal300-500RPM
one, NSKbearing[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。]Selection stage,There are many factors to consider(case:load,hardness,Operating environment),Well.NSKbearing[bearing:bearing(“Bearing”,Japanese person“Axial receptor”)It is fixed in the process of mechanical transmission and reduces the friction coefficient of load
one、FAGbearing[FAGbearing:The main shaft bearing is made of a solid inner ring、Outer ring、The ball、And a single row angular contact ball bearing consisting of a cage assembly with a solid window cage。]Vibration of Bearing vibration pairFAGbearing[FAGbearing:The main shaft bearing is made of a solid inner ring、Outer ring、The ball、And a single row angular contact ball bearing consisting of a cage assembly with a solid window cage。]The damage is very sensitive,exfoliation、impression、corrosion、crack、Wear and tear will be reflected in the bearing vibration measurement,therefore,By adopting specialFAGbearing[FAGbearing:The main shaft bearing is made of a solid inner ring、
The use environment and characteristics of electric forklift trucks 1、Four-way electric forklift;Four-way electric forklift truck set forward forklift、Side fork、Counterweight forklift truck functions in one。structurally.Its basically the same as a front lift truck,The door frame is located between the front and rear wheels,In front of the car there are two thrusting legs in the shape of arms,The front end of the leg is equipped with a support wheel,The goods can be moved back and forth in the longitudinal direction of the forklift with the door frame。When the forklift is unloaded,Fork protruding,Fork After unloading the goods, the fork is returned to the middle position near the car body,Therefore, the stability of the forklift is greatly improved。
