Construction list of hollow grouting bolt Milepost number Support type Support length（meter） remark ZK91+641-ZK91+73
A part of a boiler or industrial furnace where solid fuel is stored and burned efficiently。The whole grate mainly includes two parts: frame and grate plate。Grate plates are usually made of cast iron﹐Maintain the necessary ventilation gaps between the assembled pieces﹐And often also set under the grate can adjust the air volume of the divided ventilation chamber﹐So that air can enter the fuel layer through the gap and burn。The burnt ash is discharged manually or mechanically。The grate has a fixed type﹑mobile﹑reciprocating﹑Vibratory type and underfeed type。 Fixed grate Grate plate is generally strip or plate shape﹐It is fixed in the furnace by the surrounding frame
1“Silk planting”Repair method Screw into the body or parts，Form a wire plug to seal。Such as，A (machine)6135A crack appeared in the engine cylinder block（long30mm）。First drill a stop hole at each end of the crack，Then press1、3、5、7……Sequence Drill and tap and screw in copper screws，reorder2、4、6、8……Bore drilling，Screw the copper screws in the same way。When drilling holes, ensure that the two adjacent screws have1／3Coincidences of，Screw in depth should be the same as the thickness of the wall，Finally, tap the head of the screw with a hand hammer
Fill the processed food material into the packaging container in a predetermined amount（bottle、tank、box、barrel、bag、hose）The device inside is called a loading or filling machine。Filling machinery for filling liquid products such as drinks and beverages is often called a filling machine，Liquid filling is divided into manual filling and mechanical filling two kinds。Because the use of mechanized filling can not only improve labor productivity，Reduce product losses，Guarantee packing quality，Moreover, it can reduce the mutual pollution between the production environment and the loaded material。therefore，Modern wine production industry generally uses mechanized filling machines。 Classification of filling machines：Different loading materials（Gaseous liquid、No gas liquid
A tool is a tool used for cutting in mechanical manufacturing，Also known as cutting tools。Generalized cutting tools include cutting tools，Also includes abrasive tools。 The vast majority of knives are for machine use，But there are hands, too。Because the tools used in mechanical manufacturing are basically used to cut metal materials，therefore“cutter”The term is generally understood to mean metal cutting tools。The cutting tools used for cutting wood are called woodworking tools。 The development of knives plays an important role in the history of human progress。China was as early as BC28~before20century，Brass cones and copper cones have appeared、drill、Knives and other copper knives。Late Warring States period(
Knuckle 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。]It is mainly composed of an inner ring with an outer sphere and an outer ring with an inner sphere，Can withstand large loads。According to their different types and structures，Can withstand radial load、Axial load or radial load、Axial simultaneous joint load。Because the outer sphere of the inner ring is inlaid with composite materials
1 Regenerative heating furnace The heating value of blast furnace gas is low，The problem of insufficient heating capacity is often encountered when it is sent directly to the rolling furnace，So there has been a need to ration some coke oven gas。If coke oven gas is insufficient，Excess blast furnace gas had to be vented or burned off，Waste energy or pollute the air。Regenerative continuous heating furnace Yes20century90age，beauty、day、New technology developed by Britain and other countries，It uses high temperature flue gas to preheat the accumulator in the accumulator，Then replace the valve to let the air or gas to be burned into the regenerative tank to absorb the heat of the regenerative body(figure1)。This raises the air or burning gas500
A valve used in a water supply line to automatically discharge air(See picture The structure of the exhaust valve )。It is installed vertically on top of the pipe。When the pipe is filled with water﹐The air in the pipe can be discharged through the exhaust port﹐After filling﹐float(It is usually a float)Close the exhaust port under buoyancy﹐Stop the discharge of water。When the pipe drains﹐The float drops with the water level of the pipe﹐Exhaust open﹐The air then enters the pipe﹐To prevent the formation of vacuum in the pipeline。When the pipe is working properly﹐The air contained in the water will gradually separate out and rise﹐When the air gathered in the valve body reaches a certain amount﹐It is also discharged through the exhaust port。Against pipe fluctuation
There are many factors that cause automobile clutch jitter，Mainly from the manufacturing process and material properties of two aspects of analysis： one、Jitter caused by inaccurate dynamic balance Some manufacturers in the clutch dynamic balance，No accurately calibrated detector is used，Or not following technical standards，So the basics，That is, the manufacturer must control the dynamic balance of the clutch。Such as420Clutch pressure plate，We use the pressure plate separate dynamic balance and cover assembly dynamic balance two steps to complete，Control the removal of heavy holes in a maximum of five，Small drill to remove weight。And many manufacturers only do cost savings
Carburized steel 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。]After die quenching of the ring，Most of them show shrinkage phenomenon。After the workpiece is demoulded, it continues to shrink，We call this contraction“Elastic retraction”。The elastic shrinkage cannot be ignored，It is the key to determine the margin after turning and the size of the mill，It is very important to determine the processing allowance of the product reasonably。this
