電動フォークリフト油圧システムの日常メンテナンスポイント整理

電動フォークリフト油圧システムの日常メンテナンスポイント整理(図1)

電動フォークリフトの油圧システムは、貨物のリフトやステアリングなどのコア機能を担う重要なコンポーネントであり、その動作状態は、操作効率と操作の安全性に直接影響します。

毎日の作業前の基本的なチェックは、油圧システムのメンテナンスの最初の関門です。

作業前に、まず油圧オイルの液面検査を完了する必要があります。フォークリフトを平らな地面に駐車し、フォークを下げて液面計の目盛りを確認する必要があります。液面は最高と最低の間にある必要があります。目盛り。オイルが不足している場合は、同じ仕様の油圧オイルを補充する必要があります。異なるラベルのオイルを混合してシステムのパフォーマンスに影響を与えないようにすると同時に、オイルタンクの下部とパイプラインのインターフェイスにオイル漏れの痕跡があるかどうかを確認する必要があります。漏れが見つかった場合は、時間内に漏れ

第二に、露出した部品の外観検査を行い、油圧パイプラインに摩耗、経年劣化、ひび割れの痕跡がないか、各ジョイントに緩みがないか、リフトシリンダーとステアリングシリンダーに変形や傷がないかを1つずつ確認する必要があります。作業中にパイプラインの破裂やシリンダーの減圧などの突然の故障が発生しないようにします。

定期的なメンテナンスは、油圧システムの長期的な安定した動作を保証するための中心的な要件です。

油圧オイルの交換とろ過は、機器の仕様に従って完了する必要があります。長期間使用される油圧オイルは、酸化と不純物の増加の問題が発生します。交換するときは、古いオイルを完全に空にする必要があります。オイルタンクの内壁の堆積物を除去し、同時に油圧オイルフィルター装置を交換して、不純物がパイプラインに侵入して油圧ポンプ、制御バルブ、その他のコアコンポーネントを摩耗させないようにします。

また、定期的に圧力検出とシールチェックを実施し、油圧システムの作動圧力を標準パラメータに従って校正します。システムの長期的な過負荷運転を回避するために、安全弁の定格圧力を自由に上げないでください。シールに経年劣化、弾性低下、オイル漏れなどの問題がある場合は、同じ仕様のシールを時間内に交換して、圧力不足や持ち上げの弱さなどの問題を回避する必要があります。

日常の使用では、油圧システムの保護にも良い仕事をする必要があります。作業中は、定格負荷を超えて長時間運転しないでください。油圧システムが長時間高負荷状態にならないようにしてください。部品の老朽化を加速します。低温環境で作業する前に、一定期間アイドリングし、油圧オイルの温度を待ちます。油温が低すぎて粘度が高すぎて油圧ポンプが損傷しないように、作業を開始する前に通常の範囲に戻ります。

上記のメンテナンスポイントを遵守することで、油圧システムの故障の可能性を効果的に減らし、電動フォークリフトの動作安定性を向上させると同時に、全体的なメインテナンスコストを削減することができます。
