Hungary hydraulic cylinder,trunnion cylinder manufacturer,trunnion cylinder
(Hungary trunnion cylinder,produced by Hebei Hengyu company）
trunnion cylinder are widely used in Hungary，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed trunnion cylinder for customers from Hungary.
The assembly work of the trunnion cylinder has a great impact on the quality of the trunnion cylinder: each part must be carefully cleaned before assembly; To correctly install the sealing device everywhere: when installing the sealing ring, pay attention to its installation direction to avoid oil leakage due to installation, and its lip should be equipped with a pressure oil chamber. In addition, because it is a YX-shaped sealing ring, it is necessary to pay attention to distinguish between shaft and hole use, do not install wrong; Because the sealing device is matched with the sliding surface, an appropriate amount of hydraulic oil should be applied during assembly; The special wrench should be used when the threaded coupling is tightened, and the torque should meet the standard requirements; After the piston and piston rod are assembled, it is necessary to measure whether the coaxiality and straightness on the full length are out of whack. After assembly, there should be no blocking sensation and uneven resistance when the piston assembly moves.
Protection of the trunnion cylinder surface: During the dismantling process, safety protection should be carried out on the trunnion cylinder to prevent objects from falling and welding slag from falling to the surface, causing damage to the trunnion cylinder surface. In the process of propulsion, the damaged pipe segments should be prevented from falling and smashing, and the slurry remaining on the surface of the trunnion cylinder should be cleaned up in time.
Before purchasing the trunnion cylinder, it is necessary to master the original information and design basis, mainly including: the use and working conditions of the machine; The structural characteristics, load conditions, stroke size and operation requirements of the working mechanism; The selected working pressure and flow of the hydraulic system; The reality of materials, fittings and processes; Relevant national standards and technical specifications, etc.
If it is found that the trunnion cylinder lubrication is poor or the trunnion cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the trunnion cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the trunnion cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the trunnion cylinder center line. In this way, when the piston works in the trunnion cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the trunnion cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.
100 tons press, the cylinder diameter is 250, how much pressure?
100 tons hydraulic press, if it is a single acting hydraulic cylinder, the required oil pressure is the nominal force divided by the cross-sectional area of the cylinder piston. One hundred tons of its pressure is 1000 kN (1000000N), the diameter of the cylinder is 250 mm, its area is the circular rate multiplied by the square of the radius, is 49062.5 square mm, and then the pressure divided by the area of the oil pressure is 20.38MPa. Therefore, a hydraulic pressure of 20.38 mpa is required for a 250 diameter cylinder to obtain 100 tons of pressure.
What is the material of the cylinder support ring?
Generally, it is polytetrafluoroethylene doped with copper powder, or polyformaldehyde, and copper sleeves, there are also nylon, resin and so on.
