BYDフォークリフトコントローラーの歩行障害、電子制御アセンブリの交換およびメンテナンスポイント

BYDフォークリフトコントローラーの歩行障害、電子制御アセンブリの交換およびメンテナンスポイント(図1)

BYD電動フォークリフトの長期運転中、コントローラーの歩行障害は比較的一般的な問題であり、主に歩行力の低下、走行の逸脱、歩行を開始できないなどとして現れます。このような障害が発生した場合、保守担当者は最初に体系的な調査を行う必要があります。まず、車両の電源システムを確認し、バッテリー電圧が正常範囲にあるかどうか、および端子が緩んで酸化していないかどうかを確認します。次に、歩行モーターの配線が良好であるかどうかを確認します。モーター自体の故障の可能性を排除します。上記のリンクに異常がない場合は、コントローラーの信号出力と内部回路を検出して、交換する必要がある

電子制御アセンブリを交換する前に、十分な準備をする必要があります。まず、絶縁レンチ、マルチメータ、配線マーカーペンなどの適合する特殊な分解ツールを準備します。次に、新しい電子制御アセンブリのモデルとパラメータを確認します。元の機器と完全に一致し、仕様の不一致によるフォローアップ障害を回避します。3つ目は、事前に車両の総電源を切断し、メンテナンスプロセス中の感電のリスクを防ぐための絶縁保護対策を講じることです。

分解および組み立てプロセスは、仕様の要点に厳密に従う必要があります。古いアセンブリを分解するときは、最初にマーカーペンを使用して各配線の位置と番号を明確にマークし、後続の配線の混乱を回避します。固定ボルトを順番に取り外し、古いアセンブリを慎重に取り外し、周囲のパイプラインやセンサーを引っ張らないように注意してください。新しいアセンブリをインストールするときは、マークに対応する配線に従って、各配線がしっかりと緩んでいないことを確認してから、アセンブリの取り付け位置が平らで安定していることを確認してください。

交換が完了したら、包括的なデバッグとテストを実行する必要があります。最初に電源を入れてテストし、コントローラーのインジケーターライトが正常に点灯しているかどうか、エラーコードがあるかどうかを確認します。次に、無負荷歩行テストを実行して、フォークリフトがスムーズに移動しているかどうかを確認します。逸脱しているかどうか、およびカード現象;次に、負荷テストを実行して、歩行力が正常に回復しているかどうかを確認します。最後に、関連するパラメータは、電子

さらに、メンテナンスが完了した後は、フォローアップのメンテナンスを行う必要があります。電子制御アセンブリの接続端子と熱放散を定期的にチェックし、周囲をきれいに保ちます。フォークリフトが頻繁に急加速したり急ブレーキをかけたりしないようにします。日常業務では、コントローラーの負荷を軽減します。歩行異常が再び発生した場合は、障害の拡大を回避するために、時間内にシャットダウンして調査します。
