The installation method of hydraulic filter element and the correct use of hydraulic oil filter element

1. Before replacing the hydraulic oil filter element, drain the original hydraulic oil in the box, check the oil return filter element, the oil suction filter element and the pilot filter element for three types of hydraulic oil filter elements to see if there are iron filings, copper filings or other impurities. The wave pressure element where the oil pressure filter element is located is faulty. After the overhaul is eliminated, clean the system.

2. When replacing hydraulic oil, all hydraulic oil filter elements (oil return filter element, oil suction filter element, pilot filter element) must be replaced at the same time, otherwise it is equivalent to not changing.

3. Identify the hydraulic oil label. Do not mix hydraulic oils of different labels and brands, which may cause the hydraulic oil filter element to react and deteriorate and produce purple-like substances.

4. Before refueling, the hydraulic oil filter element (oil suction filter element) must be installed first. The nozzle of the hydraulic oil filter element directly leads to the main pump. The entry of impurities will accelerate the wear of the main pump, and the pump will be hit.

5. After adding oil, pay attention to the main pump to exhaust air, otherwise the whole vehicle will not move temporarily, the main pump will make abnormal noise (air noise), and the cavitation will damage the hydraulic oil pump. The air exhaust method is to directly loosen the pipe joint on the top of the main pump and fill it up directly.

6. Regularly do oil testing. The wave pressure filter element is a consumable item, and it needs to be replaced immediately after it is usually blocked. 7. Pay attention to flushing the system fuel tank and pipeline, and pass the fueling device with filter when refueling.

8. Do not let the oil in the fuel tank come into direct contact with the air, and do not mix old and new oil, which is helpful to prolong the service life of the filter element.

For the maintenance of the hydraulic filter element, it is an essential step to perform regular cleaning work. In addition, if it is used for a long time, the cleanliness of the filter paper will be reduced. According to the situation, the filter paper should be replaced regularly and appropriately to achieve better Filtering effect, and then if the model equipment is running, do not replace the filter element.
