The invention provides a Doppler transducer replacement method. It is ensured that dismounting of an original base is not influenced by means of preparation before the dismounting of the original base; when the original base is dismounted, firstly a guide plate welded on an outer plate around the base is dismounted, an original welding seam is removed by adopting a carbon arc gouging mode so as toreduce a gap; and when a new base is welded, a fillet weld between the outer plate and the Doppler log transducer is full penetration, the Doppler log transducer is dismantled, then a new high-frequency Doppler log transducer is installed, and finally tightness inspection is conducted. The Doppler transducer replacement method has the beneficial effects that the blank of a ship technical Dopplertransducer replacement technology in the market is filled, the problem of local cavitation caused by installation of the flow guide cover is solved, and the speed measurement precision of a Doppler log on a ship is improved.
本发明提供一种多普勒换能器的更换方法,通过原基座拆除前的准备工作,确保拆除原基座时不受影响,在拆除原基座时,先拆除基座周围焊在外板上的导流板,采用碳弧气刨方式去除原有焊缝,以减小间隙,在新基座的装焊时,与外板的角焊缝为全焊透,拆除多普勒计程仪换能器,再安装上新高频多普勒计程仪换能器,最后进行密性检查。本发明的有益之处在于,填补了市场上船舶技术类多普勒换能器更换技术的空白,解决了因安装导流罩引起的本地空化问题,提高多普勒计程仪在船上的测速精度。
