A ZL40 loader has encountered difficulties in starting, weak driving, deviation after # braking, and a small amount of oily smoke and a burnt smell on the left front wheel after stalling. When judging the fault, first stepped on the foot brake valve, and heard the exhaust sound after releasing the pedal, so the first possibility was ruled out. Then, unscrewed the oil pipe joint from the gas-liquid master cylinder to the disc brake cylinder, stepped on the foot brake valve several times,
and found that there was brake fluid spraying out of the joint and there was a large pressure, which ruled out The second and third possibilities. Dongfeng Honda Civic offers a discount of 17,000 yuan! Five Skoda Jingrui models officially listed on Monday, Buick Excelle HRV discount rate remains at 20,000 GM/Chrysler finally won the U. ZL40 loader adopts dual-pipeline air-push oil disc brake system. Finally, we judged that the fault was in the brake cylinder
Therefore, in order to measure the yield characteristics of the material, it is stipulated that the permanent residual plastic deformation is equal to a certain value (usually 0.).77%, the amount of cementite in the structure is also less than 12%, so After removing a part of ferrite, it will form pearlite with cementite, and there will be excess, so the structure of this steel is ferrite + pearlite. 5, the yield ratio (σs/σb)
The ratio of the 624 ball bearing point (yield strength) of the steel to the tensile strength is called the yield ratio. That is to say, cementite and ferrite in this specific ratio will disappear at the same time if they disappear during a phase change (during heating), and if they appear, both will appear at the same time. According to the hardness of the test material, it is expressed in three different scales: HRA: It is the hardness obtained by using a 60kg load and a diamond cone indenter, and is used for extremely hard materials (such as cemented carbide). Tempering is mostly used in conjunction with quenching and normalizing.65-0.2 of the original length). At this point, this structure and The phase transition of pure metals is similar.
