What you must know - common faults of hydraulic system of hydraulic accumulator

The loss of pressure makes the liquid viscous, and there is inevitable friction when it flows in the pipeline. Therefore, the fluid in the hydraulic capsule accumulator must consume some energy in the process of flow.This part of the energy loss is mainly the pressure loss.There are two kinds of pressure loss: the along loss and the local loss.The wholesale loss of cixi capsule accumulator is the pressure loss caused by friction when liquid flows over a certain distance in a straight pipe with the same diameter.Local loss is the pressure loss caused by sudden change of section shape of pipeline, change of flow direction or other forms of flow resistance.The total pressure loss is equal to the sum of the loss along the path and the local loss.

Due to the inevitable existence of pressure loss, the rated pressure of the pump is slightly greater than the large working pressure required by the system during operation. Generally, the large working pressure required by the system can be multiplied by 1.3.The coefficient of 1.5.Flow loss in a hydraulic system, each pressure element has a relatively moving surface, such as the inner surface of the cylinder and the outer surface of the piston, the need for relative movement, so there is a certain gap between them.If one side of the gap is high pressure oil and the other is low pressure oil, the high pressure oil will flow through the gap to the low pressure area, causing leakage.

At the same time, due to the hydraulic component seal is not complete, some of the oil will leak to the outside.The actual flow caused by this leak is slightly reduced, which is what we call the flow loss.Flow loss affects the speed of movement, it is difficult to avoid leakage, so the rated flow of the hydraulic system pump is slightly greater than the large flow required when the system is working.It is also generally possible to estimate the large amount of traffic required for the system to work by multiplying it by a factor of 1.1 to 1.3.
