A Common Cause of Slow Actuation of Hydraulic Components is

During the operation of the hydraulic system, we often encounter the phenomenon that the hydraulic components run slowly. The reason affecting the speed of the hydraulic cylinder can be attributed to the flow of hydraulic oil, that is, the total amount of liquid flowing into the cylinder per unit time, so such failures must first determine whether it is the cause of the flow reduction. Flow loss and insufficient flow (reduction) will cause the hydraulic cylinder to slow down and slow the execution action. Common reasons for slow movement of hydraulic cylinders are:

1. A most common cause of slow actuation of hydraulic components is hydraulic oil pollution: hydraulic oil is polluted not only carries impurities, but also oil deterioration will produce colloidal precipitation, the dirt or gum sediment carried in the hydraulic oil stuck in the flow valve or directional valve core, or block the valve hole, will make the hydraulic cylinder action failure. Impurities make the piston rod stuck with the cylinder barrel or the hydraulic cylinder blocked, making the hydraulic cylinder slow or even unresponsive.

2. Internal leakage: The internal leakage of the hydraulic cylinder or the reversing valve reduces the actual flow of the hydraulic oil, so the movement speed of the hydraulic cylinder is reduced.

3. Air entering the hydraulic oil: the bubbles in the hydraulic oil will cause the hydraulic cylinder to slow down, the possible reasons are oil leakage, the liquid level of the hydraulic oil tank should be checked, the seals and pipe joints on the suction side of the hydraulic pump, and whether the suction pipe filter is too dirty.

4. Insufficient flow rate of hydraulic pump: Possible reasons are insufficient oil suction caused by filter element blockage, long use time of hydraulic pump, or serious wear of pump parts due to oil pollution, internal leakage, and decreased volumetric efficiency.

5. Hydraulic oil viscosity increases: the viscosity of hydraulic oil increases, the fluidity of oil decreases, causing the flow rate to decrease and the flow rate is insufficient, resulting in slow action of the hydraulic cylinder. Common causes of increased viscosity of hydraulic oil are: increased viscosity of hydraulic oil due to lower temperature, oxidation of hydraulic oil, mixed with high-viscosity oil.

If hydraulic components produced by our elephant fluid power are used, this phenomenon will be greatly reduced. Our directional valves have a series of advantages such as compact structure, sensitivity and high efficiency. Our hydraulic components are made of aluminum alloy, which has high strength, corrosion resistance, light weight and high density. It is not only easy to install, but also suitable for operation in various environments, even if the hydraulic oil contains impurities and dirt, it can still run with high strength, and there will be no card valve, valve core wear, etc., which greatly ensures the work efficiency of the hydraulic system.
