The influence of the yaw and oscillating hammer and the centering of the rapping center #3 The electric pulsating hammer of the electric precipitator is not good, and the electric field of the oscillating hammer is modified after the mass of the original vibrating hammer is reduced. The location becomes smaller, and most of the damage of the slamming hammer is broken at this place, and the rapping cannot be performed, and the ash accumulation at the pole line is severe, causing the corona to be closed. We have already replaced it during the overhaul. Part of the vibrating hammer splint fixing bolt is loose, the pin shaft is easy to break, causing the vibrating part to not vibrate, and the vibrating hammer will cause the air locker to jam after being detached. During the minor repair and body maintenance process of this year, thousands of vibrating hammers were inspected and processed one by one. A total of 500 vibrating hammers were loosened, the splint bolts were loose, and the pin shaft was broken. Due to the poor installation quality and the wear of the vibrating bar fixing bolt gasket, the center of the rapping hammer is deflected from the center of the vibrating anvil and the oscillating rod, and the ash deposition of the pole plate affects the dust removal efficiency. The center deflection of the vibrating anvil and the oscillating rod is gradually corrected during the overhaul process.
The influence of the anode plate is more off the plate clamp between the anode plate and the anode plate, and the installation is difficult. The spacing between the plates of the plates also partially falls off, the plates are oscillating to the left and right, the pole spacing is in a fluctuating state, and the secondary voltage is unstable, which affects the dust removal efficiency. The fixing bolt gasket between the anode plate and the rapping rod is seriously worn, the vibrating rod sinks, rubs against the base or even jams, the vibration acceleration is insufficient, and the electrode plate and the pole line are not easy to vibrate, which affects the dust collection. The impact on dust removal efficiency is also serious. There are also some vibrating rods with poor installation quality. The electric field is short-circuited during operation, and the second time is zero. The whole electric field is in a paralyzed state, which greatly affects the overall efficiency of the electrostatic precipitator. During the maintenance process of this year, each plate row was inspected, and more than 500 decoupling rods and more than one card were processed, and more than 100 anode plate spacing clips and plate clamps were replaced.
Digital conductivity sensors have two electrodes and four electrodes. Compared with analog conductivity sensors, digital conductivity sensors have higher accuracy and stability through digital measurement and signal processing technology. They provide accurate measurements and reduce errors due to sensor drift or interference. Digital conductivity sensors usually have a digital output interface, such as a serial communication interface (such as RS485, MODBUS, etc.) or a digital bus (such as I2C, SPI, etc.). This allows for easy connection and communication of the sensor with other devices or data acquisition systems. Daruifuno's digital conductivity sensors have built-in temperature compensation and are capable of temperature compensation. Since conductivity is closely related to temperature, the built-in temperature compensation function can provide more accurate and reliable conductivity measurement results. In addition, another advantage of the digital conductivity probe is that it is plug-and-play, internally stores calibration data, and can be calibrated offline. The material of the digital Conductivity Sensor is PPS plastic, stainless steel and titanium alloy. Users can choose the appropriate conductivity probe according to their own application.
