固定升降机http://www.jnyuexiang.com/液压系统泄漏会影响到整个升降机的工作,下面济南悦翔机械制造的有关专家给大家介绍一下如何预防固定升降机液压系统泄漏?
1、固定升降机要做到合理地选择密封装置,必须熟悉各种密封装置的形式和特点、密封材料的特性及密封装置的使用条件,如工作压力的大小、工作环境的温度、运动部分的速度等。把实际的使用条件与密封件的允许使用条件进行比较,必须保证密封装置有良好的密封性能和较长的使用寿命。固定升降机密封材质要与液压油相容,其硬度要合适。固定升降机胶料硬度要根据系统工作压力高低进行选择,固定升降机液压系统的压力髙则选择胶料硬度高的密封件,压力过高,还需设计支承环。
Fixed lifts to achieve a reasonable choice of seals, must be familiar with the characteristics of various forms and seals, the conditions of use of the sealing material properties and sealing device, such as the size of the working pressure, the temperature of the working environment, the speed of the moving parts. The actual conditions of use and allows the use of seals, compared to the condition, the sealing device must ensure a good sealing performance and long life. Fixed sealing material should be compatible with the lift hydraulic oil, its hardness to the right. Fixed lift rubber hardness according to the system operating pressure level is selected, the hydraulic pressure of the fixed lift system Gao selecting High hardness rubber seal, pressure is too high, the need to design the supporting ring.

2、固定升降机零件设计时要有导向角,以免装配时损伤密封件。在有锐边和沟槽的部位装配密封圈时,要使用保护套,以免损伤密封件。设置液压管路时应该使油箱到执行机构之间的距离尽可能短,管路的弯头、特别是90°的弯头要尽可能少,以减少压力损失和摩擦。固定升降机液压系统中应尽量减少管接头,系统漏油有30%~40%是由管接头漏出的。
Lift parts designed to have a fixed orientation angle, so as not to damage the seal assembly. In sharp edges and seal groove when assembling parts, to use the protective cover, so as not to damage the seal. Should be set so that when

the distance between the hydraulic lines to the tank actuator as short as possible, the pipe elbow, in particular by 90 ° elbows to as little as possible to reduce pressure losses and friction. Fixed hydraulic elevator system should minimize fittings, leakage system 30% to 40% by pipe joint leakage.

3、控制固定升降机液压系统温度的升高,一般从油箱的设计和液压管道的设置方面着手。为了提髙油箱的散热效果,可以增加油箱的散热表面,把油箱内部的出油和回油用隔板隔开。油箱液压油的温度一般允许在55~65℃之间,最高不得超过70℃。当自然冷却的油温超过允许值时,就需要在油箱内部增加冷却水管或在回油路上设置冷却器,以降低液压油的温度。
Fixed hydraulic elevator control system temperature, the general design of the tank from a set of aspects and hydraulic pipes. In order to improve the cooling effect of the fuel tank Gao, can increase the cooling surface of the tank, to separate out the oil inside the tank and back to the oil separator. The temperature of the hydraulic oil tank is generally allowed between 55 ~ 65 ℃, the maximum shall not exceed 70 ℃. When the natural cooling of the oil temperature exceeds the allowable value, you need to increase the cooling water pipe inside the tank or set back to the oil cooler on the road, in order to reduce the temperature of the hydraulic oil.

4、选择合适固定升降机http://www.jnyuexiang.com/结构的液压元件和管接头,应根据工作可靠性和经济性进行选择。
Select the appropriate structure fixed lift hydraulic components and fittings, should be selected according to reliability and economy.
