The way to make static electricity disappear
There are two main ways to eliminate static electricity: one is to create conditions to accelerate the leakage or neutralization of static electricity; the other is to control the process to limit the generation of static electricity.
Two methods
Leakage method and neutralization method. Grounding, humidification, adding antistatic agents, etc. are all leakage methods, and the use of induction static eliminators, high-voltage static eliminators, radiation static eliminators, and ion current static eliminators are all neutralization methods.
Process control method, including measures taken in material selection, process design, equipment structure and operation management.
1, control the flow rate
Lowering the flow rate reduces the degree of friction and can reduce the generation of static electricity. The amount of static electricity generated by the flow of oil in the pipeline is proportional to the square of the oil flow rate, so controlling the flow rate is an effective way to reduce the generation of electrostatic charges.
2, control the way of refueling
In order to avoid liquid spraying and impact in the container, oil should be injected from the bottom or the oil pipe should be extended to close to the bottom of the container. It is generally stipulated that before the crane tube is immersed, the flow rate can only be limited to less than 1m/s. After immersion, it can be filled at the aforementioned recommended flow rate.
3. Speed up the dissipation of electrostatic charge
4. Eliminate additional sources of static electricity
5. Choose a reasonable mix of materials
6, closed division method
Elimination of human body static electricity
To eliminate static electricity on the human body, grounding, wearing anti-static shoes, anti-static overalls and other specific measures can be used to reduce the accumulation of static electricity on the human body. In order to ensure safe operation, during work, try not to do things related to the electrification of the human body. If you do not approach or touch live objects, do not wear or take off work clothes in the workplace. Do not carry metal objects that are not related to work, such as keys, coins, watches, rings, etc., when operating and patrolling in dangerous places with static electricity
