introduction：As shown in the figurelAs indicated，A check valve is a directional control valve in which the air flow can only flow in one direction and not in the opposite direction。Its working principle is the same as the hydraulic check valve。Compressed air enters through the mouth of the body，Overcome spring force and friction to open the check valve port，Compressed air fromPFlow toA；whenPWhen there is no compressed air in the mouth，In the spring force andAmouth(cavity)Under the action of residual force；The port is closed state，divertAtoPAir blockage。Check valves are used in situations where reverse flow of air is not allowed，Such as the air compressor to the air tank when，A check valve is arranged between the air compressor and the gas tank，When the air compressor stops working，Prevents compressed air in the tank

introduction：The main reasons for the oil leakage of the reducer are as follows：1、In a closed gear box，Each pair of gears engages to give off heat，With the long running time，Gradually increase the temperature in the gearbox，The volume of the gearbox remains unchanged，Increase the pressure inside the box，The lubricating oil in the box passes through the flying oil，Sprinkle on the inside of the gearbox。Because the oil permeability is relatively strong，Press down in the box，Where the seal is not tight，The oil seeps out of there。 2、The unreasonable design of gearbox structure causes oil leakage，Such as the design of the gearbox without ventilation hood，The reducer cannot equalize the pressure，The pressure in the gearbox increases，Thats when the oil spills。

introduction： Whether imported or domestic 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。]There will be a day of invalidity，General fault，It is the end of the bearings life。If less than failureKOYOBearing life。Then there is the problem of bearings，Resulting in less than bearing life，Premature failure，And now the bearing quality is good，Generally not

introduction： White spot is a kind of internal defect produced in the forging cooling process。The morphology of the crack is fine filament-like sharp Angle crack on the transverse low-power specimen，The fracture is silver speckled。Cr-Ni-MoThe white spots on the longitudinal fracture of steel forgings are irregular in shape，Disparity in size，Minimum long axis size only2mm，The largest is24mm。 The white spot is a kind of brittle sharp edge crack，Can be extremely harmful，It is a very dangerous defect in martensitic and pearlite steels。 The cause of the white spot is the enrichment of hydrogen in the tensile stress zone under the action of stress，The steel produces what is called hydrogen embrittlement，Brittle fracture，

introduction：Resulting rolling 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 are three reasons for the noise：Bearing dust、Have marks、Improper lubricant（Use the wrong lubricant、Lack of lubricant、Lubricants harden with age）Here are some answers for you。 Dust causes the bearing to make noise If the bearing will attack non-periodic vibration，and
