Mexico hydraulic cylinder,tailboard balance cylinder manufacturer,tailboard balance cylinder(Mexico tailboard balance cylinder,produced by Hengyu Hydraulic Co., Ltd)
tailboard balance cylinder are widely used in Mexico,because of excellent fatigue and impact resistance,no need for deceleration device,long service life.So our company has designed tailboard balance cylinder for customers from Mexico.
The "O" ring can be used as an auxiliary seal inside the tailboard balance cylinder, and the elastic force of the "O" ring makes the sealing slip ring close to the sealing surface, generating sealing pressure to achieve sealing. When the internal hydraulic pressure increases, the "O" ring will further deform and squeeze the slip ring, thereby increasing the sealing pressure and improving the sealing performance. The structure has the characteristics of low friction coefficient, good wear resistance, automatic compensation for wear and absorption of hard particles in the tailboard balance cylinder, and can be completely sealed.
After the tailboard balance cylinder is installed, lubricating grease should be added to the relative moving parts such as earring and middle hinge shaft before trial operation.
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 tailboard balance 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.
When the tailboard balance cylinder is installed, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the tailboard balance cylinder head, earring (or middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent rigid interference and cause unnecessary damage.
What are the main technical parameters of the hydraulic cylinder?
Parameters are as follows: 1, cylinder diameter, inner diameter size; 2, import and export diameter and thread parameters; 3, piston rod diameter; 4, cylinder pressure, cylinder working pressure, calculation is often used test pressure, less than 16MPa multiplied by 1.5, higher than 16MPa multiplied by 1.25. 5, cylinder stroke; 6. Is there a buffer? According to the working conditions, the piston rod extension contraction is generally buffered if the impact is large. 7, the installation of the cylinder.
What are the differences between hydraulic cylinder and pneumatic cylinder, what are their advantages and disadvantages?
Hydraulic Cylinder: small body and large force, constant speed and variable speed (easy to change), the adjustment of output is also convenient, and the degree of freedom of transmission is high. However, maintenance costs and installation costs are high, and there is the trouble of mild oil pollution. Pneumatic Cylinder: easy to control, low price, easy access to energy. But the force is small, and can not achieve the effect of stable speed. The gas-liquid pressurized cylinder has the advantages of both of the above: environmental protection and energy saving, easy control, and simple adjustment. However, the output of the trip has certain restrictions, so it is more suitable for short trips, large output, but also environmental protection and energy saving and low configuration of the occasion. Because the pressure used in the pneumatic system is generally in the range of 0.2-1.0Mpa, the cylinder is not suitable for high power component.
