Clarifying the upper and lower maintenance values for the working pressure of machinery and equipment depends on the condition of your equipment. For example, when adjusting the total flow rate, if the total flow rate drops to a necessary level, the working pressure at the inlet and outlet of your pump will be close to the maximum pump head, which will cause vibration in the pump and pipeline, posing a necessary threat to the service life of the pump. At this time, your limited maintenance value should also be lower than this working pressure, in order to maintain your pump. For example, when the working pressure at the inlet and outlet of your pump is lower than a certain value, the actual effect of your filter will decrease. At this point, your lower limit value should be higher than this value.
