How often does the filter need to be replaced?

The filter screen is an indispensable component in the whole hydraulic system. Its function is to filter impurities in hydraulic oil, thus prolonging the service life of hydraulic oil and protecting hydraulic machinery. The filter screen mainly filters impurities, and everyone knows that the service life of the filter screen is very long. When the impurities in the filter reach a certain level, we need to clean or replace the filter.

So how often does the general filter need to be replaced?

1. Some filters have no transmitter. At this time, the pressure gauge can be investigated. When the filter screen is blocked, it will affect the pressure of the whole hydraulic system. Therefore, when the pressure in the hydraulic system becomes abnormal, we should open the filter to replace the filter screen.

2. According to our own practical experience, roughly observe how often we change the filter element and record the time. At this time, we can change the filter element!

3. At present, there is no clear figure for the service time of the filter element, so it should be judged according to the different use environment and the different materials. When the screen and filter are used together, the general filter will be equipped with an emitter. When the blocking pressure difference of the filter element is greater than the set value, the transmitter will send out an alarm signal, and then the filter screen can be stopped and replaced.

Of course, you should know that the number of screen cleanings is not unlimited, because some particles are blocked and accumulated, and some cannot be completely eradicated. Coupled with the fatigue coefficient of the metal itself, therefore, each filter element has its service life, and the detailed use time should be judged according to daily use. Therefore, when we choose the screen, we should follow the principle of reducing the cost and not affecting the filtering function.

Hailai screen has high welding strength, enhanced fluid impact resistance, good firmness, good quality and high screen frame strength. Injection molding is a new type of plastic with high temperature resistance 140℃ and good toughness, thus improving the shock resistance and service life of the screen, and the composite material has better wear resistance and stability. The service life is twice that of other screen manufacturers, up to 500 hours, and the original screen is about 480 hours. The composite frame screen of Jiangsu Hailai Petroleum Equipment Co., Ltd. is not easy to rust, and its storage life is greatly prolonged, which can be stored for more than 5 years. The hard side screens they produce are all made of imported composite materials, which have high strength and good wear resistance. By injection molding, the screen is welded to the screen by a hot-melt machine. The surface of the screen is flat and tight, and its service life is far better than other products.
