After our bread brick used for a long period of time, it must be carefully checked hydraulic cylinders have no problems! Usually hydraulic pump pressure cylinder wall will be produced for longitudinal cracks, scratches and welding parts vicious and processing parts breakage! We want to find fault timely, it must know the cause of the fault! Today we'll introduce several Cause bread brick hydraulic cylinder failure! First, the inner wall of the cylinder wall crack weak resistance when the cylinder by conventional drilling, boring, when the rolling process, which is based on steel tube to come in as a reference, the outer diameter of the coaxial good, the cylinder wall thickness is generally more uniform, generally does not produce longitudinal cracks. However, after a large-scale promotion now through honing steel cold drawn or direct excised as a cylinder, as in the cold drawn steel blanks 孔作基 is accurate, it is very volatile, resulting in uneven cylinder wall thickness. The weakest point in a certain direction, it is easy to follow the longitudinal cracks caused by cold drawing direction. The minimum wall thickness of the cylinder such that may arise after cold drawing process should be the strength and stiffness (the cylinder wall to avoid swelling) of the check, the calculation. There is a foreign body after scratching cylinder hydraulic cylinder seriously bad whipped into rigid foreign body in reciprocation, foreign body in the piston and the cylinder walls consultations move bound to scratch the cylinder wall, resulting in a trench or pull-cylinder, seizures! Thus there is a problem caused by the pump cylinder wall brick bread! Located in the ancient city of Pingyao in Shanxi Province, is a city with 2700 years of history and cultural city Caizhuan small machine, China is now one of the best preserved ancient city four large color brick machine, is currently China's only success in the whole city, declared World Heritage The ancient town. Pingyao formerly known as "Pottery", Ming Dynasty, for the defense of South alien interference, built walls, Hongwu years (1370) rebuilt the old wall repair expand on the basis of a comprehensive package and brick, which is the earliest bread produced ancient brick house. After Jingtai, Masanori, Longqing and Wanli generations been repaired 10 times, automatic updates tower Caizhuan machine, additional enemy units. Kangxi forty-three years (1704), because the emperor passing patrol west of Pingyao and the building of four large towers, making the city even more spectacular. The total perimeter walls of Pingyao 6163 meters, about 12 meters high wall. Streets within the city walls, pavement, city building retains Ming and shapes; outside the walls of said town. This is an ancient and modern architecture all into one, each other, endless reverie good ground. Aerial view of the ancient city of Pingyao, but absolutely amazing road. The square planar walls Caizhuan machine, shaped like a turtle-like, six gates, and one each in the north and south, east and west of each two. South Gate city for the glans, outside two wells symbol turtle eyes. North gate of Gumi, is the lowest point of the whole city, the city that all water must flow out through this. Urn city four things on Simon, under Simon, the East Gate of the Urn gates are to Nankai, the shape of turtle claws reach, only under the East Gate Urn straight outside the gates opened to the east, making the city is said to be afraid when the turtle crawl go to the left leg straightened, tied twenty miles from the city of foot table.
