The effect of static electricity on the coding equipment Many people often disagree, and it is often the case that the problem arises. In the process of coding, a large amount of static electricity is generated due to friction during the operation of the inkjet conveyor belt. If it cannot be eliminated in time, it will easily affect the normal operation of the nozzle. The ink droplets are sufficiently affected by static electricity to deviate from their trajectory, causing the scene to smear and fly. Excessive static electricity is very likely to damage the nozzle and computer equipment is prone to garbled and crashes under the influence of high static electricity. In serious cases, the board of the machine is burnt. Therefore, it is extremely important to take correct and effective measures to eliminate the static electricity generated by the equipment. Buried ground wire is a good way to eliminate static electricity. The grounding of the printer equipment is strict and should not be connected to the public ground. The common ground wire and the ground wire in the entire power supply network may have been connected to other large equipment, and static electricity may be generated. Therefore, each printer ground should be grounded separately according to the standard. The correct way to bury the ground wire is to connect the copper plate with an area of ​​not less than 0.5 square meters through the copper wire and the device to the pre-excavated wet environment with a depth of less than 1.8M and pour the brine. After the operation is successful, the equipment is operated for more than 1 hour. The residual static value of the equipment is measured. The measurement method is to adjust the multimeter to the AC 200-speed measuring meter and connect it to the neutral line of the 220V stable power input and the ground line. The absolute value is the residual value of the equipment. The electrostatic value is preferably less than 1 ohm. After the ground wire is buried and tested, it should be measured frequently. If the value is found to be greater than 1 ohm or the fluctuation is large, the ground wire should be inspected immediately. Many companies think that after the ground line is buried, there is no need to manage it. This is a wrong idea. The ground wire needs regular inspection, and it is best to form a mechanism and check it regularly.
