What are the reasons for the failure of the hydraulic valve of the hydraulic press
3. Corrosion.
Too much water or acidic substances mixed in the hydraulic oil of the hydraulic press will corrode the surface of the relevant parts in the hydraulic valve after long-term use, and make the accuracy and sealing effect of the parts invalid.
4. Fatigue.
Under the long-term alternating load work, the spring in the hydraulic valve of the hydraulic press will become soft due to fatigue, the valve seat will be fatigued, and other damages such as cracks will occur. If the spring is too soft or shortened, it will affect the working position and normal reset of the valve core, so that the system cannot work normally.

mechanical power press are raising the stakes of social marketing, but they also ease the sales process by providing ways for automatic power press machine to effectively interact with customers.
The specific reasons for the failure of the hydraulic valve of the hydraulic press are as follows:
1. Deformation.
When the stress of hydraulic valve parts in work and the external load stress during use are greater than the yield strength of the parts material, the parts are deformed and fail to complete their normal functions. The valve core is bent and deformed or the spring is deformed, and the deformation of the parts will reduce the flexibility of its movement, resulting in unstable pressure in the hydraulic system or slow state transition process.
2. Wear.
The movement of hydraulic parts, valve sleeves, valve bodies and other mechanical parts constantly generates friction during use, which makes the size, shape and surface quality of the parts change, and the quality decreases and fails. The wear or deformation of the valve core will cause the valve to leak and reduce the efficiency. At the same time, the metal on the surface of the parts will fall off due to wear, which increases the amount of impurities in the hydraulic system and aggravates the degree of wear.
3. Corrosion.
Too much water or acidic substances mixed in the hydraulic oil of the hydraulic press will corrode the surface of the relevant parts in the hydraulic valve after long-term use, and make the accuracy and sealing effect of the parts invalid.
4. Fatigue.
Under the long-term alternating load work, the spring in the hydraulic valve of the hydraulic press will become soft due to fatigue, the valve seat will be fatigued, and other damages such as cracks will occur. If the spring is too soft or shortened, it will affect the working position and normal reset of the valve core, so that the system cannot work normally.
