油圧オイルパイプとオイルシール損失の原因、BYDフォークリフト修理部品の共有

油圧オイルパイプとオイルシール損失の原因、BYDフォークリフト修理部品の共有(図1)

電動フォークリフトのコアパワートランスミッションコンポーネントとして、油圧システムの安定した動作は、機器の操作効率と耐用年数に直接影響します。なかでも、油圧オイルパイプとオイルシールは、油圧システムの気密性を確保するための重要なコンポーネントです。日常の使用で損失が発生すると、油圧オイルの漏れや電力不足などの故障が発生しやすく、メインテナンスコストが増加します。

油圧オイルパイプの損失は、主にいくつかの要因に起因します。第一に、高圧衝撃に長期間さらされると、フォークリフトの頻繁な昇降と操舵操作により、オイルパイプは圧力変化の影響を繰り返し受け、パイプ壁に徐々に疲労亀裂が発生します。特に接合部に応力が集中し、破損しやすくなります。第二に、外部摩耗、作業環境の砂や鋭い物体がオイルパイプの表面を傷つける可能性があります。時間内に発見されない場合、損傷箇所は徐々に拡大し、最終的に油圧オイルの漏れにつながります。第三に、油温が高すぎます。油圧システムの長時間の高負荷運転により、油温が上昇し、オイルパイプの材料の経年劣化が加速し、耐圧

オイルシールの損失にも複数のインセンティブがあります。1つ目は、シール自体の自然な経年劣化です。使用時間が長くなると、オイルシールのゴム材料が酸化や高温環境により硬化・ひび割れ、本来の弾力性が失われ、部品に密着できなくなり、シールが故障します。2つ目は、組み立てが不適切であることです。メンテナンス中にオイルシールの取り付け位置をずらして過度に圧迫すると、シール面に不均一な力がかかり、短時間で漏れが発生する可能性があります。また、作動油中の不純物も重要な影響要因です。不純物がシール面に入ると、オイルシールリップが継続的に摩耗し、シール効果が損なわれ、損失速度が速くなります。

保守部品を選択する際には、適合性の問題によるその後の損失の増加を回避するために、材料とサイズが元の部品と一致していることを確認するために、適合仕様の油圧オイルパイプとオイルシールを優先的に一致させる必要があります。オイルパイプは、高圧と耐摩耗性に優れた高品質の材料を使用する必要があります。オイルシールは、油圧システムの動作環境に適応するために、優れた耐高温性と耐油性を備えている必要があります。日常のメンテナンスでは、オイルパイプの表面にひびや損傷の痕跡がないか、ジョイントに緩みがないか、オイルシールにオイル漏れの兆候がないかを定期的に確認する必要があります。同時に、油圧システムの油温を合理的に制御し、長時間の高負荷運転を回避し、劣化し

油圧オイルパイプとオイルシールの損失の原因を深く理解し、メンテナンスパーツを合理的に選択し、日常のメンテナンスと管理を行うことで、電動フォークリフトの油圧システムの故障率を効果的に減らし、機器の全体的な耐用年数を延ばし、安定性を向上させることができます。操作プロセスの安全性。
