What are the main manifestations of abnormal flow in the hydraulic system? The following editor will give you a brief introduction.
l) Due to filter clogging and other reasons, the hydraulic pump is insufficiently supplied with oil and the hydraulic system is short of oil, resulting in slow or non-operation of the working mechanism, resulting in failure or even out of control of the actuator.
2) Leakage of hydraulic pump, hydraulic cylinder, hydraulic valve or pressure pipeline not only increases fuel consumption, but also prevents the working pressure from rising, making the output force of the working mechanism insufficient, or even unable to form pressure in severe cases.
3) Frequent fluctuations in flow aggravate the vibration and noise of the system, while greatly reducing the performance of the filter. Therefore, the degree of oil pollution cannot be controlled within a predetermined range, which seriously threatens the normal operation of the hydraulic system. When the flow pulsation is large, it will cause hydraulic shock, which is the main cause of damage to some hydraulic equipment.
4) When some parts of the hydraulic system leak too much, the pressure of the hydraulic oil can be converted into heat energy. If the cooling fin capacity is limited or the performance of the cooling fin is poor, the equilibrium temperature of the hydraulic oil will rise, which will cause the oil temperature to rise in a short time, the viscosity of the oil will decrease, and the leakage will increase further, resulting in a significant decrease in volumetric efficiency and the efficiency of the entire system. Rubber seals, hoses, etc. are prematurely aged and functionally lost, and the movement speed of the actuator in the hydraulic system should meet the specified speed range. It is required that there is no crawling phenomenon at low speed and no hydraulic shock at high speed; the speed switch is stable, and the speed change is small when the load is changed.
