Hydraulic filters are divided into several parts based on their pressure level and the position where they are absorbed. Hydraulic filters are divided into different forms such as the following:
Hydraulic suction filter
The main function of the suction filter is to prevent particles from entering the pump inlet. The size of suction filters can reach 150 microns or even more, that's why this filter is also known as suction strainer.
Hydraulic pressure filter
This filter must be clean to be used. The amount of pressure tolerance in pressure filters in industrial activity reaches 420. The size of particle and pollutant absorption in pressure filters has reached four to twelve microns. These filters are usually placed either in a linear form or in a block form in the hydraulic chamber.
Hydraulic return filter
These filters are used when particles have gone into the oil and there is a possibility of their entering the system. The purpose of these works is to prevent entry by absorption Prevent particles from entering the system. Of course, the presence of a cartridge filter inside this filter determines the size of the particles, which should be between 21 and 40 microns. Among those mentioned, it can play a role in their size, but this filter has no role in the cleanliness of the hydraulic oil filter.
The hydraulic filter system usually has two oil filters, but today's hydraulic filters that engineers make can have several filters and these filters can be kept in different parts.
In some cases, filters can be Pressure and return filters should be installed in parallel or double in the system. In this case, the filters are installed in the hydraulic system with the same filtration action.
One of the advantages of installing in this way is that when one of the filter ducts is blocked, other ducts can be used so that the passage of oil is not delayed. For a hydraulic filter, tasks such as opening, cleaning, replacing, closing the assembly and reinstalling have very important roles. And these actions must be done according to the necessary orders and requirements.
Hydraulic oil filter
The basic role of the hydraulic oil filter is to catch the particles and contaminants in the oil and help the hydraulic device to be more efficient. be them
