Product Description

Zoomlion crane accessories hydraulic oil return filter element/hydraulic oil tank filter element,Suitable for Zoomlion cranes 25 tons, 30 tons, 35 tons, 50 tons and 70 tons.

Function:

Crane hydraulic oil return filter element mainly has the following roles:
1. Filtering impurities: in the crane working process, hydraulic oil after passing through each hydraulic component, will carry some metal particles, rubber impurities and other pollutants. Return oil filter element can effectively filter these impurities, to prevent them from re-entering the hydraulic system, to avoid wear and damage to the hydraulic pump, valves, cylinders and other key components, thereby extending the service life of hydraulic components.
2. Keep the oil clean: to ensure the cleanliness of the hydraulic oil is the key to the normal operation of the hydraulic system. The return filter element through the continuous filtration of pollutants in the return oil, so that the hydraulic oil is always maintained at a certain level of cleanliness, to reduce the impact of oil contamination on the performance of the system, to maintain the stable operation of the hydraulic system.
3. Control the spread of pollution: If the return oil is not filtered directly back to the tank, the pollutants may be in the hydraulic system constantly circulating and spreading, resulting in increased pollution of the entire system. The existence of the return filter element can prevent the spread of this pollution, the pollutants will be concentrated filtered out, so that the hydraulic oil in a relatively clean environment cycle, help to improve the reliability of the hydraulic system and work efficiency.
4. Protection of other cartridges: in the hydraulic system, there are usually other filtration devices such as suction cartridges. The return filter element of the return oil after preliminary filtration, can reduce the number of pollutants into the suction filter element, reduce the burden of the suction filter element, so as to better protect the entire hydraulic system filtration system, to extend the service life of other filter elements.
5. Maintain stable system pressure: When the oil return filter element is clogged, it will make the oil return resistance increase, which will lead to higher pressure in the oil return pipeline. When the return oil filter element normal work, can keep the oil back to the smooth, maintain the pressure balance of the system, help to ensure that the hydraulic system in the normal working pressure range of stable operation, to avoid abnormal pressure caused by the failure and safety hazards.
In summary, the crane hydraulic oil return filter element in the crane hydraulic system plays a vital role, it can not only effectively filter impurities, keep the oil clean, control the spread of pollution, but also protect the other filter element, maintain the system pressure stability, so as to ensure that the crane hydraulic system of high efficiency, stability and safe operation.
