In the last piece, we analyzed what cause hydraulic hose burst in excavator. The reasons are bad quality hydraulic hose, high pressure of the hydraulic system, high temperature of hydraulic oil and mixing the different hydraulic oil. This time let’s talk about the other factors.
If the operator drive the excavator roughly, the huge crush load will cause instantaneous impact pressure in the hydraulic system. The huge impact pressure will cause leakage or even burst in the connection point of high pressure joint and hose. Further cause the lifespan reduce greatly. Besides, rough operation will influence the durability of other parts, then cause frequent mechanical faults. Therefore, you should be more gentle when drive an excavator. In the meantime, never do high-strength and dangerous actions.
Hydraulic hose corrosion
Most of the hydraulic hoses in the market have corrosion resistance. But it’s a fact that rubber products will become fluffy and go bad if touch with oil for a long time. Thus, you should avoid the corrosive fluids like diesel touch the hose. Besides, you should clean the surface of hydraulic hose regularly.
Abnormal vibration of hydraulic hose
There will be oil fluid loping when gear pump and piston pump work. This loping will cause hydraulic hose high frequency vibrate and it’s can’t be eliminated. The long-term abnormal vibration will cause hydraulic hose fatigue wear. Therefore, you should check the clamps and protection sleeve. Because once the clamps loose, the hydraulic hose may wear and even wear through.
As you see in these two pieces, there are mainly 7 reasons that cause hydraulic hose burst. Since set up in 2006, OrientFlex aims to provide the most cost-effective hoses to the world. We make every effort to become the one-stop supplier of hoses and fittings worldwide. That’s also the goal that we fighting for all life long.
