重慶升降機采用液壓雙管路防爆安全閥，該液壓安全閥的工作油管采用液壓雙管路，當一根液壓油管破斷后，液壓安全閥的一個(gè)閥芯立即將該管路關(guān)閉，使空中作業(yè)機構安全保持在原位，同時(shí)液壓安全閥的另一個(gè)閥芯工作，立即將另一條液壓油管自動(dòng)接通，機構仍維持正常工作，確保機器和人身安全。那么貨梯高壓膠管破斷是什么原因呢？

1、貨梯工作時(shí)液壓缸隨升降臺運動(dòng)，高壓膠管反復進(jìn)行撓曲動(dòng)作，因而產(chǎn)生疲勞破斷。
Zhejiang freight elevator hydraulic cylinder when working with the lifts movement, high-pressure hose repeated flexing action, resulting in fatigue breaking.

2、貨梯的負載變化較大，液壓系統內將產(chǎn)生液壓脈動(dòng)，脈動(dòng)壓力達到一定值時(shí)，高壓膠管會(huì )產(chǎn)生破斷。
Zhejiang large freight elevator load changes will generate hydraulic pressure pulsations within the hydraulic system, pulsating pressure reaches a certain value, high pressure hose will have broken.

3、貨梯高壓膠管由于質(zhì)量差，膠管與金屬接頭的扣壓連接強度不夠，液壓系統中峰值壓力出現時(shí)，出現拔管現象。
Zhejiang freight elevators due to the poor quality of the high-pressure hose, metal hose fittings withhold connection strength is not enough, when the peak pressure in the hydraulic system occurs, there extubation phenomenon.
