What are the maintenance methods of hydraulic oil filter element?

Hydraulic oil filter element has been widely used in our daily life. As we all know, hydraulic oil filter element is a consumable product, and it often encounters various problems of blockage, causing us a lot of trouble. In order to prolong its life, we need to know something about maintenance. For example, if it needs to be replaced immediately after being blocked at ordinary times, pay attention to cleaning the tank and pipeline of the system. When refueling, the refueling device with a filter should be used to avoid direct contact between the oil in the tank and the air, and the old and new oil should not be mixed. Want to know more about the maintenance of hydraulic oil filter element? Let's learn!

Filter element maintenance is as follows:

1. Before replacing, release the original hydraulic oil, check the return oil filter element, oil suction filter element, pilot filter element, to see whether there is iron scrap copper scrap or other impurities, if there may be hydraulic component fault, repair and eliminate, clean the system.

2. When changing hydraulic oil, all hydraulic oil filter elements (return oil filter element, oil suction filter element, pilot filter element) must be replaced at the same time, otherwise it is equivalent to no change.

3. Distinguish the label of hydraulic oil. Different labels and different brands of hydraulic oil are not mixed, which may react and deteriorate to produce flocculent. Recommended use of the excavator designated oil.

4. Before refueling, the oil suction filter element must be installed. The pipe mouth covered by the oil suction filter element leads directly to the main pump.

5. Oil to the standard position, the hydraulic tank is generally provided with an oil level gauge, see the level gauge. Pay attention to the way of parking. Generally, all cylinders are recovered, that is, the forearm and bucket are completely extended and landed.

6. After filling the oil, pay attention to the main pump to exhaust air, otherwise the whole car will temporarily have no action, the main pump abnormal sound (air sonic boom), heavy air pocket damage the main pump. Exhaust air method is directly at the top of the main pump to loosen the pipe joint, directly fill can be.
