Ireland hydraulic cylinder,press machine hydraulic cylinder manufacturer,press machine hydraulic cylinder(Ireland press machine hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory)
press machine hydraulic cylinder are widely used in Ireland,because of high work efficiency,excellent fatigue and impact resistance,no need for deceleration device.So our company has designed press machine hydraulic cylinder for customers from Ireland.
In the process of using the press machine hydraulic cylinder, sometimes such a problem will occur, the press machine hydraulic cylinder can not act immediately after the instruction of the press machine hydraulic cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil press machine hydraulic cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.
press machine hydraulic cylinder use should try to avoid sealing belt into the press machine hydraulic cylinder. As a simple sealing material, polytetrafluoroethylene plastic sealing tape is often used in installation and inspection, and if the winding method of the linear and ribbon-shaped sealing material is wrong, the sealing tape will be cut off and enter the press machine hydraulic cylinder. The wire belt seal will not have any effect on the winding of the sliding part, but it will cause the check valve of the press machine hydraulic cylinder to fail to operate or the buffer regulating valve can not be adjusted to the end. For the circuit, it may cause the action of the reversing valve, the relief valve and the reducing valve to fail.
Analysis of commonly used seals: The wear ring and slip ring commonly used on the press machine hydraulic cylinder are generally made of polytetrafluoroethylene + graphite, because pure polytetrafluoroethylene is easy to produce plastic creep, which is only suitable for low pressure and low wear resistance conditions. If the sealing ring used is a composite material formed after adding graphite filler, the performance can be effectively improved, the ability to resist plastic creep is increased by 2 to 3 times, the initial deformation caused by the load is reduced by 30 to 60% : the rigidity is increased by 2 to 3 times: the dimensional stability under heat is increased by 2 times, and the hardness is increased by l0 to 15%.
When the press machine hydraulic cylinder is customized, if there are high requirements for the quality of the press machine hydraulic cylinder, it is best to use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface of the small crack, preventing the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the press machine hydraulic cylinder can be improved. By rolling forming, a cold working hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving the wear resistance of the inner wall of the press machine hydraulic cylinder and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the matching property.
How big is the motor and oil pump for the 80 cylinder?
Pump motor selection is not only related to cylinder diameter but also speed system, it is recommended to provide system diagram and speed requirements, generally speaking, most of the 80 cylinder on the market is equipped with 3-4KW motor, 10-20 oil pump.
How to calculate the tonnage of hydraulic cylinder? The tonnage of the cylinder refers to the output force of the cylinder under rated working pressure: 1, for single rod piston hydraulic cylinder, it can be calculated by the area of the circle corresponding to the inner diameter of the cylinder A (square centimeter), and the rated working pressure of the system p (mpa), the value is equal to 10pA kg force, and the ton is 0.01pA. 2, for the double rod piston hydraulic cylinder, with A(square centimeter) to indicate the cylinder cylinder diameter and piston rod outer diameter defined by the ring area, with p (mpa) to indicate the rated working pressure of the system, the output force of the cylinder is 0.01pA ton force.
