What is the appropriate flow control for hydraulic filters?

The selection of hydraulic filter flow rate should be determined based on the actual needs of the hydraulic system, usually designed to be 1.5 to 4 times the required flow rate of the hydraulic system. This design principle aims to ensure that the oil can smoothly pass through the filter during the operation of the hydraulic system, while ensuring that the filter can effectively intercept and remove impurities from the oil.

The main factors affecting the flow rate of hydraulic filters include the demand of the hydraulic system, the displacement of the oil pump, the resistance and filtration accuracy of the filter, as well as the content of impurities in the system and the actual usage environment. The working pressure and flow demand of the hydraulic system are important factors determining the filter flow rate. The larger the displacement of the oil pump, the faster the circulation speed of the oil in the hydraulic system, and the corresponding increase in the required filter flow rate. The resistance and filtration accuracy of the filter can also affect the flow rate, and excessive resistance or high filtration accuracy may lead to a decrease in flow rate.

In addition, there are various types of hydraulic filters, such as bag filters, which have a theoretical flow range of 0.5 to 1200T/H and a filtration accuracy of 0.5 to 200um. The design of bag filters can choose the number of filter bags according to the requirements, and the equipment materials are diverse, including stainless steel, titanium, etc., to meet the actual needs of different sites.

Therefore, selecting the appropriate hydraulic filter flow rate is of great significance for ensuring the normal operation of the hydraulic system and extending its service life. Regular cleaning of the hydraulic system and replacement of filters are important measures to maintain stable flow.
