Reconstruction of phosphating slag-removal system in automobile coating line
According to some problems existing in phosphating slag-removal system in automobile bodywork coating line, such as liquid level defect, liquid level sensor failure, ftlow mismatch and a small outcome of slag, the old phosphating slag-removal system was reconstructed. The reform and adjustment methods were introduced, including selecting a liquid level sensor with resistance to heat, pollution and corrosion and adjusting its installation from bottom horizontal to top vertical; changing the pump operation mode for adjusting the flow rate of the clear water tank; increasing the amount of precipitation cones from 2 pairs to 6 pairs to improve the collection capability for concentrated phosphating bath, thereby enhancing the amount of slag, etc. The slag-removal effect of phosphating system after reconstruction is improved greatty and the system runs more steadily.
