BYD地牛昇降故障対応交換部品参考案

BYD地牛昇降故障対応交換部品参考案(図1)

ロジスティクス、倉庫、ワークショップの取り扱いシナリオでは、柔軟で効率的な特性を備えた電動ダウが広く使用されており、リフトシステムの故障はBYDダウのより一般的な問題タイプです。関連する障害が発生した場合、問題のあるアクセサリを正確に特定し、合理的に交換することが、機器の機能を迅速に回復するための鍵となります。

地牛が弱く持ち上げられない場合、それらのほとんどは油圧シリンダーシールの経年劣化と摩耗に関連しています。シールが油圧オイルによって長期間侵食され、頻繁に摩擦されると、隙間が発生しやすくなり、油圧オイルが漏れて持ち上げ力に影響を与えます。このとき、対応するシリンダーシールキットを交換する必要があります。操作前に油圧システムの圧力を解放し、シリンダーの内壁を清掃して不純物の残留を防ぎ、新しいシールが適切に取り付けられ、二次漏れを防ぐ必要があります。

地元の牛が下降カードを持っていて、スムーズに後退できない故障が発生した場合、制御弁に問題がある可能性が高い。制御弁のバルブコアは、長期間使用すると摩耗して変形したり、作動油中の不純物が詰まったりして、作動油の流れが悪くなる可能性があります。この場合、適合モデルの制御弁を交換する必要があります。交換時には、油圧パイプラインの清掃に注意を払い、取り付け後、リフト動作を繰り返しテストして、下降プロセスがスムーズでカードがないことを確認してください。

上げ下げの過程でフォークのバランスが崩れ、片側が高く、片側が低い場合、それは主に上げ下げチェーンまたはスプロケットの過度の摩耗または破損が原因です。チェーンが長期間荷重にさらされると、伸びたり錆びたりしやすくなり、スプロケットの歯面が摩耗すると、トランスミッションの噛み合わせが悪くなります。このとき、摩耗の程度に応じてチェーンまたはスプロケットを交換する必要があります。取り付け後、チェーンの張力を調整して、両側のチェーンの張力が同じになるようにし、不均衡の問題が再発しないよう

一部の土地牛はリフト高さが不足している状況があり、これは通常、ギアポンプの性能低下に関係している。ギアポンプの内部漏れが深刻な場合、十分な油圧を確立できず、リフトストロークが基準に達しません。この場合、仕様に合ったギアポンプを交換し、設置後、油圧システムの圧力が機器パラメータに準拠しているかどうかを確認し、リフト高さが正常に戻ることを確認する必要があります。

また、ジニウリフトトリガが故障し、ストロークを正確に制御できない場合は、リミットスイッチが故障している可能性があります。リミットスイッチは、振動やほこりの影響を長期間受けており、接触不良や損傷を起こしやすくなっています。このとき、同じモデルのリミットスイッチを交換し、取り付け後にスイッチの感度をテストして、リフティングストロークの制御が正確であることを確認する必要があります。

地上牛の昇降故障に遭遇した場合は、故障現象を観察して部品の問題を事前に調査し、交換用に適合する通常の部品を選択し、動作仕様に厳密に従って設置を完了することをお勧めします。機器のその後の安定した動作を確保します。
