粉塵防爆リチウムフォークリフト全体の防爆検査に関するプロセス

粉塵防爆リチウムフォークリフト全体の防爆検査に関するプロセス(図1)

粉塵防爆リチウム電気フォークリフトの機械全体の防爆試験は、粉塵環境での安全な動作を確保するための重要なリンクであり、機器が防爆安全基準を満たしていることを確認するために、標準化されたプロセスに厳密に従う必要があります。

テストの事前準備は、テストがスムーズに実行されるようにするための基礎です。まず、テスト担当者が機器の防爆構成と技術パラメータを理解できるように、機器の防爆設計スキーム、部品の材料説明、工場検査レポートなど、機器の基本情報を収集する必要があります。同時に、防爆マルチメーター、絶縁テスターなどの標準に準拠したテストツールを準備して、テストデータの正確性と信頼性を確保する必要があります。さらに、テストサイトをクリーンアップし、無関係な破片を取り除き、デバイスの実際の動作のダスト環境条件をシミュレートして、オンサイトテストの安全で準拠した環境を作成する必要があります。

現場検査リンクはプロセス全体の中核であり、複数の側面から検査作業を実行する必要があります。まず、外観と構造の検査を行い、機器のシェル、防爆ドア、シールなどの部品の完全性を確認し、損傷、変形、緩みがないことを確認し、ほこりが機器の内部に侵入しないようにします。同時に、防爆標識の明確さと標準性を確認して、標識が関連する標準要件を満たしていることを確認します。

次に、防爆検査の重点内容である電気系統の検査を実施する。検査員は設備の回路絶縁性能をテストして、絶縁抵抗が安全基準を満たしていることを確認し、短絡による火花を避ける必要がある。同時に、防爆配線箱、ケーブル導入装置などの部品の締め付け程度を検査し、密封がしっかりしていることを確認し、粉塵が電気キャビティに入って安全上の危険を引き起こすのを防ぐ。さらに、リチウム電池システムの防爆保護装置の機能テストを行い、過電圧、過電流保護機構が正常に起動できることを確認する必要がある。

最後に、性能シミュレーションテストを実行し、ほこりっぽい環境での機器の動作状態をシミュレートすることにより、機器の防爆機能が正常であるかどうかをテストします。テスト担当者は、シミュレートされたほこりっぽい環境での起動、運転、積み下ろしなどの通常の操作を完了させ、火花や過熱などの異常がないかどうかを観察し、実際の作業条件での機器の防爆の信頼性を検証します。

検査が完了した後、検査データを整理して分析し、関連する基準と組み合わせて設備の防爆コンプライアンスを判断する必要がある。検査結果が要件を満たしている場合は、正式な防爆検査報告書を発行し、設備の検査結論とコンプライアンス状況を明確にする不合格項目がある場合は、関係者に問題をフィードバックし、改善後に検査を再実施するよう指導し、設備が防爆安全基準を満たすまで。
