The role of the hydraulic system relief valve
2024-01-16 09:19
In the hydraulic system, the function of the relief valve is to prevent the pressure in the system from exceeding the rated value, thereby protecting the safe operation of the entire system. In the system, when the system pressure reaches the set value of the relief valve, the relief valve will open and release the excess flow, thus playing a protective role. So, specifically, what is the role of the overflow valve? Let's take a look at it.
1. Prevent overload. If the pressure in the hydraulic system is too high, it will cause the oil pump, motor and other components to malfunction. The relief valve can effectively control the maximum pressure of the system to avoid equipment damage due to overpressure. In addition, the system can maintain a constant flow rate by adjusting the size of the throttle hole, so as to ensure that each actuator can work normally.
2. Adjust the working speed. In the work, if it is found that the speed of the actuator is too fast, or the action time is too long, it will cause damage to the equipment. At this time, we can adjust the size of the throttle hole and change the flow rate of the liquid, so as to achieve the adjustment of the working speed of the actuator. purpose.
3, limit or cut off the high pressure oil. When the pressure of the hydraulic system is too high, it will cause the liquid in the oil tank to spray out, and even "cylinder explosion", which seriously threatens the safety of the staff. Therefore, we can use the size of the throttle hole to limit or cut off the high-pressure oil to avoid danger.
4. Prevention of pollution. In the system, if some media with high impurity content are used, it is easy to cause the filter to be blocked, which will cause the filter screen to be unable to be replaced in time and affect the normal operation of the equipment. At this time, we can use the throttle holes to let the excess gas out, so that not only can the filter be cleaned, but also can extend its service life.
