What causes hydraulic oil overflow in manual forklifts
When hydraulic oil overflows during the use of a manual forklift, we need to stop using it. There must be a problem with the manual forklift in this state. If we continue to use it, it is likely to cause the manual forklift to be irreparable and completely scrapped. So, what is the specific reason for hydraulic oil overflow?
Firstly, manual forklifts have encountered serious overload problems during use. The hydraulic system in an overloaded state will bear loads that are difficult for itself to bear, and the pressure on the hydraulic oil will increase, causing the entire hydraulic system to be in an extremely high pressure state. This force can easily cause the sealing device to loosen, and hydraulic oil can be squeezed out of the gaps, and in severe cases, the oil cylinder may even burst.
Secondly, it is caused by high temperatures. High temperature environments can have a certain dilution effect on hydraulic oil, thereby reducing its viscosity. In addition, the sealing material under high temperatures can also be greatly damaged, resulting in damage to the sealing performance of manual forklifts and making it easier for hydraulic oil to overflow from the cylinder.
In the face of these two situations, Guanhang suggests avoiding overloading and prolonged use under high temperatures and direct sunlight to ensure the long-term effective use of manual forklifts.
