What is the stiffness of the hydraulic element? What does that mean?
It is understandable that when an oil cylinder pushes the load forward, when the load suddenly increases: If the stiffness is large, the speed of the cylinder is not changing or changing. If you have small stiffness, you will have a sudden decrease in velocity.
Generally used to indicate the difference of the speed regulating valve and throttle valve, regulating valve need to keep the valve pressure difference before and after the same, after the valve pressure, the valve before the pressure has increased automatically, and traffic load, stiffness; Throttling valve load and flow affect, stiffness is small.
Stiffness is the ability of the component to resist deformation. The stiffness is not enough to make the components too big to change and affect the normal work. For gear pump, it is the stiffness of the driving shaft, and the shaft deformation gear is not meshed properly, which leads to the oil absorption area and the shadow zone guide, affecting the oil and oil of the gear pump. For blade pump, it is the stiffness of the blade, the deformation of the blade, the sealing of the oil area and the oil absorbting area, and the influence of the normal operation. For the plunger pump, the plunger is the stiffness, the plunger bending deformation, the influence plunger in the cylinder of the normal operation, affecting the pump oil.
