What is a hydraulic suction filter on an excavator?
A excavator must be carefully designed and set up to ensure the normal operation of its various components, one of which is the hydraulic system. This system is crucial for the excavator to perform its functions, and hydraulic oil is the fluid that makes this system operate. However, as the number of excavator uses increases, various impurities and dirt may gradually accumulate in the system, which not only affects the performance of the entire system, but also leads to damage to the oil pump and other key components, leading to their non operation.
To solve the above problems, excavators are usually equipped with a hydraulic suction filter, which is a special filter located in the system and mainly serves to prevent foreign substances from entering the hydraulic system. This filter is an efficient mechanical device that not only filters out small particles, but also removes sediment, ensuring the cleanliness of hydraulic oil and protecting the hydraulic system from various wear and corrosion. During the suction of hydraulic oil by the excavator, this filter will prevent small particles from being brought into the hydraulic system, ensuring that each hydraulic component receives clean hydraulic oil.
Hydraulic suction filters typically consist of a filter screen, interceptor, and inlet filter built into a casing. This filter can be installed on the hydraulic oil tank or suction pipeline, and can be modified according to design requirements. During use, when the oil pump sucks the oil into the hydraulic oil tank, the hydraulic suction filter will filter out various small impurities and oil sludge, allowing the hydraulic oil to continue to circulate. When the filter reaches its maximum service life, the indicator set on the filter will indicate the need to replace the hydraulic suction filter.
The hydraulic suction filter cannot completely avoid the generation of various impurities in the hydraulic system, but it can filter out these impurities in a timely manner to ensure the continuous and normal operation of the system. As a high-strength and durable construction machinery, it is necessary to set up a hydraulic suction filter for excavators. By installing this filter, the reliability and lifespan of the hydraulic system can be greatly improved, which is beneficial for reducing maintenance costs.
Overall, hydraulic suction filters play a very important role in the hydraulic system of excavators, preventing impurities and pollutants from entering the hydraulic system, ensuring the cleanliness and normal operation of the system, and also having a positive impact on the service life and maintenance costs of the entire excavator.
