          Speaking of filter factories, we will think of those filters that emerge endlessly. Generally, filters can be classified into many kinds according to their different functions. One of the common ones is the oil suction filter, which is located in the suction pipeline of the pump. It filters the pollutants from the residual pollutants in the tank through the air holes to protect the pump. However, in order to avoid the occurrence of pump cavitation, full attention must be paid to pressure loss. When producing each filter product, the filter factory has fully endowed these products with their own unique characteristics.
          There are also several common filters in life, such as high-pressure pipeline filters, which are usually located in the outlet pipeline of the pump, to protect pollutants from entering the system. Therefore, the concentration of pollutants can be controlled. However, because it is a high-pressure main circuit, it should be subject to pump pulsation and pressure impact, the strength should be carefully considered, so the material of filter elements.
          There is also a reflux filter - usually located in the system's oil return pipeline, although it is a low-pressure pipeline, but according to the operation of the transmission device, there will be pulsation or pressure impact, so the material and strength of components should be fully considered. Import pump. Its function is to capture pollutants generated or intruded into the system before returning to the tank. Therefore, it is an effective and important filter for controlling pollution concentration.
          Circulation filter - set on the return road of the tank cycle, even if the system is not working, the contaminants in the tank can be trapped, and the capacity of the system is large. Therefore, it is often used when strict cleanliness is required, so the efficiency of reducing pollution concentration is good. In addition, a cooler is installed, which has the advantages of simultaneous cooling and easy maintenance. But special pumps and motors are needed, and the cost is high.
          After that, it is worth mentioning that it is also a few things that need to be paid attention to. The installation position of the oil filter in the hydraulic system is usually installed at the oil suction port of the pump. The purpose is to filter out the larger impurity particles to protect the function of the hydraulic pump. Surface oil filters are usually installed on the suction path of pumps. In general, pressure loss is less than 0.02 MPa. It can also be installed on the outlet oil road of the pump, so it seems that the purpose of installing the oil filter here is to filter out the pollutants that may invade the components such as valves. It can be seen that the filter factory is conscientious in producing these purification equipment.
