升降貨梯高壓膠管破斷有哪些原因？
1
、升降貨梯http://www.8kvv.com/作業(yè)時液壓缸隨升降臺運動
，高壓膠管反復(fù)進行撓曲動作，因而產(chǎn)生疲勞破斷
；升降貨梯的負載變化較大
，液壓系統(tǒng)內(nèi)將產(chǎn)生液壓脈動，脈動壓力達到一定值時，高壓膠管會產(chǎn)生破斷
。
When operating the hydraulic cylinder with cargo lifter lifts sports, high pressure hose repeated flexing action, resulting in fatigue breaking; changes in the freight elevator lift a heavy load will generate hydraulic pressure pulsations within the hydraulic system, pulsating pressure reaches a certain value, high pressure hose will produce breaking.

2、升降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(tǒng)中峰值壓力出現(xiàn)時，出現(xiàn)拔管現(xiàn)象
。
Cargo lifter 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.

、因此升降貨梯http://www.8kvv.com/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
，機構(gòu)仍維持正常工作，確保機器和人身安全
。
Therefore, cargo lifter hydraulic dual pipeline explosion relief valves, the hydraulic valve working hydraulic tubing double lines, when a hydraulic hose broke off, a hydraulic spool valve immediately closed the pipeline, so that air operations security agencies remain in place, while the other hydraulic valve spool work immediately will automatically connect another hydraulic tubing, agencies still maintain normal work, ensure that the machine and personal safety.
