Analysis of Causes of High Filtration Pressure of Hydraulic Oil Filter

During the use of the hydraulic oil filter, the oil is processed under vacuum, so the pressure is also very important! Ultra high pressure will shorten the life of the filter element
Life. Anyone who has used a hydraulic oil filter knows its working principle, which relies on the positive pressure generated by the oil pump to provide the driving force of the oil to make the filter
The oil flows out. But sometimes there will be excessive pressure in the oil filter. There are many reasons for this phenomenon.
The following is the reason analysis and solution of hydraulic oil filter before and after the pressure is too high:
1. The filter pressure suddenly rises and then drops suddenly, please check whether the fine filter element is broken or damaged; if it is damaged, the filter element needs to be replaced, and the original factory is recommended to replace the filter element
Home filter!
2. The oil output pressure of the hydraulic oil filter unit is too high, and the oil output flow is significantly reduced. Please check and confirm:
a. Whether the filter element of the fine filter is blocked;
b. Whether the oil seal of the oil pump is worn.
3. Hydraulic oil supply: If the pressure of the oil filter is too high during heating, please check and confirm.
a. Whether the steering of the oil pump is correct;
b. Whether the filter element of the coarse filter is seriously blocked;
C. Whether the shaft seal of the oil pump is damaged.
4. In order to ensure the effect of oil filtering, please make sure to clean the oil suction pipe and oil outlet pipe of the oil filter at any time;
5. During the operation of the filter element unit of the oil filter unit, because the oil pump sucks in air, this will affect the filtration flow rate. In order to achieve the rated filtration of the oil filter unit
The flow rate of the device, please check whether the oil pipe has been inserted and the sealing of the parts between the fuel tank and the oil suction port is reliable, whether the oil suction port is away from the oil surface, whether the oil has been sucked or sucked
Whether the pipe is on the wall of the oil barrel;
6. After the oil filter has been used for a period of time, the initial filter is blocked by contaminants and the oil intake rate is slow. Stop the machine and remove the oil filter element to
Clean or replace the filter element;
7. After a period of use, the fine filter element will gradually be blocked by contaminants, resulting in excessive pressure. When the pressure gauge value reaches 0.4MPa, the fine filter element needs to be cleaned and replaced in time.
