Ireland hydraulic cylinder,self-locking hydraulic cylinder manufacturer,self-locking hydraulic cylinder(Ireland self-locking hydraulic cylinder,produced by Hengyu Group)
self-locking hydraulic cylinder are widely used in Ireland,because of clever hydraulic energy conversion,excellent temperature resistance,high work efficiency.So our company has designed self-locking hydraulic cylinder for customers from Ireland.
When the self-locking hydraulic cylinder is installed, the piston and the self-locking hydraulic cylinder head and other parts have large mass, large size and large inertia, even if there is a lifting equipment auxiliary installation, because the specified clearance is small, no matter how hard it will be put into, therefore, the end of the piston or the self-locking hydraulic cylinder head boss is easy to cause scars when it hits the inner surface of the self-locking hydraulic cylinder wall. The solution to this problem: for a large number of small products, the use of autocratic assembly oriented tools during installation; For heavy, thick and large large and medium-sized self-locking hydraulic cylinders, only careful and careful operation can be avoided.
The main role of the self-locking hydraulic cylinder: the self-locking hydraulic cylinder is an executive element in the hydraulic transmission system, which is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic motor realizes continuous rotary motion, while the self-locking hydraulic cylinder realizes reciprocating motion. The structure of the self-locking hydraulic cylinder has three categories: piston self-locking hydraulic cylinder, plunger self-locking hydraulic cylinder, swing self-locking hydraulic cylinder, piston self-locking hydraulic cylinder and plunger self-locking hydraulic cylinder to achieve reciprocating linear motion, output speed and thrust, swing self-locking hydraulic cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the self-locking hydraulic cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The self-locking hydraulic cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.
When the self-locking hydraulic cylinder is customized, if there are high requirements for the quality of the self-locking 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 self-locking 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 self-locking hydraulic cylinder and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the matching property.
The pressure, temperature, medium and speed of different types of seals are not the same, water-ethylene glycol medium (HFC) can not be sealed with polyurethane, it can only use rubber seal; When the self-locking hydraulic cylinder is running fast, it must be sealed with slip ring, such as Sterseal, Glairing, GD1000K, TDI, etc., when the running speed is slow, Yx, U, V combination seals can be used; Fluorine rubber seal is used in high temperature and high pressure environment; When the running speed is fast, the buffer sleeve and buffer valve must be considered.
The pressure gauge of the hydraulic station reaches 20MPa. How many tons of weight can the hydraulic cylinder lift? How to convert?
20Mpa=200kg/cm^2 The weight of the cylinder with a cross-sectional area of 1 square centimeter can be lifted is 200kg, so F=200X3.14X (125/2) ^2 =24531kg =24.5 tons.
How to calculate the hydraulic cylinder pressure, how much pressure can put up how much weight?
There is a formula for air pressure, hydraulic pressure, water pressure: F=P×S type: f-cylinder or hydraulic cylinder output, unit is Newton (N) P- pressure, unit is Mpa S- effective area, unit is square millimeter (mm2), note: is the effective area, in the hydraulic cylinder to subtract the cross-sectional area of the piston rod.
