重慶升降機(jī)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(dāng)一根液壓油管破斷后，液壓安全閥的一個閥芯立即將該管路關(guān)閉，使空中作業(yè)機(jī)構(gòu)安全保持在原位，同時液壓安全閥的另一個閥芯工作，立即將另一條液壓油管自動接通，機(jī)構(gòu)仍維持正常工作，確保機(jī)器和人身安全。那么貨梯高壓膠管破斷是什么原因呢？

1、貨梯工作時液壓缸隨升降臺運(yùn)動，高壓膠管反復(fù)進(jìn)行撓曲動作，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(fù)載變化較大，液壓系統(tǒng)內(nèi)將產(chǎn)生液壓脈動，脈動壓力達(dá)到一定值時，高壓膠管會產(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(qiáng)度不夠，液壓系統(tǒng)中峰值壓力出現(xiàn)時，出現(xiàn)拔管現(xiàn)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.
