-18℃冷凍倉庫リチウム電気フォークリフト防寒防湿構造の紹介(図1)

-18℃の冷凍倉庫環境では、低温と高湿度の二重の影響がリチウムフォークリフトの性能と寿命に課題をもたらすため、対象を絞った防寒防湿構造設計が特に重要です。

バッテリーシステムの防寒防湿設計

冷凍倉庫内の低温はリチウム電池の活性を低下させ、高湿環境は電池の短絡を引き起こしやすいため、リチウムフォークリフトの電池システムは多層保護構造を採用している。電池モジュールの外部は高密度絶縁保温材料で包まれ、低温による電池への熱損失を減らし、電池の作動温度を合理的な範囲に維持する。電池ケースは一体化シール技術を採用し、耐食性シールゴムストリップと協力して、外部水蒸気の侵入経路を遮断すると同時に、通気弁を予約して内外の気圧をバランスさせ、温度差による内部結露を避ける。

電子制御システムのシール保護

電子制御システムはフォークリフトのコア制御ユニットであり、低温および高湿度の環境では回路障害が発生しやすくなります。電子制御ボックスは完全密閉構造を採用しており、ボックス本体の接合部には、水蒸気の浸透を防ぐために、低温環境の要件を満たす防水性と防塵性を備えたシールゴムリングが取り付けられています。内部の電子部品は、-18℃の環境でも信号を安定して伝送できるように低温適応製品を採用しており、一部の主要部品には、低温適応性をさらに向上させるための小型断熱装置も装備されています

車体と歩行システム防寒防湿

フォークリフト本体の板金接合部はスポット溶接とシーラントで処理され、隙間からの水蒸気の侵入を減らします。ウォーキングモーターの外側には、モーター巻線への低温の影響を低減し、モーターの耐用年数を延ばすための断熱シールドが取り付けられています。ハブベアリングとトランスミッションコンポーネントは、低温環境でも優れた潤滑性能を維持し、グリースの凝固によるランニングカードを回避するために、低温グリースを使用しています。

これらの防寒防湿構造は互いに協力して、-18℃冷凍倉庫環境がリチウム電気フォークリフトに与えるマイナスの影響を効果的に低減し、フォークリフトの長期安定運転を保障し、低温倉庫作業の需要を満たすことができる。
