The harm of static electricity in the filter system

In air filtration, especially in industrial air filtration systems, filter materials are mainly used for continuous operation of dust collection systems and purification of smoke and steam, etc. And their workload is relatively large. Dust particles have dispersibility and suspension. The dispersibility makes it have a large contact surface area. When it comes in contact with various parts in the filtration system and porous filter materials, the probability of electrification increases. Suspension makes it easy to suspend in the air and difficult to settle. It is always insulated from the earth, and every particle may be charged and accumulated. The static electricity of the particles or components in the air filtration system is released from high potential to low potential, and a discharge phenomenon (such as electric spark, etc.) occurs. In the oil filtration and separation system, the main function of the filter material is to remove the particulate impurities carried in the oil liquid. In order to maintain the cleanliness of the oil, prevent system failures caused by the wear and blockage of system components and related components, and the deterioration of the oil. As a multi-component system, the hydraulic system has a high degree of integration. The system contains strong electric components such as motors and electric valves and weak electric components such as servo valves and sensors. In addition, the complicated working environment around the system often causes it to transmit fluid energy while inevitably generating static electricity and the conductivity of the oil is low. Frictional static charges are easy to accumulate, and electrostatic discharge after a certain degree will cause damage to filter elements and hydraulic components, and aging of fluid performance. In turn, it causes abnormal control, which poses a great threat to the stability of the entire fluid system.
