液压闭式系统克令吊应急下放功能优化设计

液压克令吊是船舶上普遍使用的一种装卸货设备,在闭式系统中,液压泵的进油管直接与执行元件的回油管相连,工作液体在系统的管路中进行封闭循环。闭式系统结构较为紧凑,油口空气接触机会较少,空气不易渗入系统,故传动的平稳性好。该文通过对闭式液压系统克令吊应急下放功能优化设计,在满足各船级社入级要求的基础上,大幅提高了克令吊设备的安全性和可靠性,避免了克令吊设备出现故障而导致事故发生的潜在风险。

Optimization Design of Emergency Lowering Function for Closed Hydraulic System Crane

The hydraulic system crane is commonly used in ships.The oil inlet pipe of the hydraulic pump is directly connected with the oil returning pipe of the hydraulic motor.The closed hydraulic system has a compact structure.Less air is contacted the oil.The air is not easy to penetrate into the system,so the stability of the transmission is good.In this paper,through the optimization design of the emergency lowering function of the closed hydraulic system,the safety and reliability of the crane are greatly improved.The potential risk of accidents caused by the failure of the crane is avoided.
