固定升降機http://m.kkwl.net/液壓系統(tǒng)泄漏會影響到整個升降機的工作,下面石家莊悅翔機械制造的有關專家給大家介紹一下如何預防固定升降機液壓系統(tǒng)泄漏?
1、固定升降機要做到合理地選擇密封裝置,必須熟悉各種密封裝置的形式和特點、密封材料的特性及密封裝置的使用條件,如工作壓力的大小、工作環(huán)境的溫度、運動部分的速度等。把實際的使用條件與密封件的允許使用條件進行比較,必須保證密封裝置有良好的密封性能和較長的使用壽命。固定升降機密封材質(zhì)要與液壓油相容,其硬度要合適。固定升降機膠料硬度要根據(jù)系統(tǒng)工作壓力高低進行選擇,固定升降機液壓系統(tǒng)的壓力髙則選擇膠料硬度高的密封件,壓力過高,還需設計支承環(huán)。
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、固定升降機零件設計時要有導向角,以免裝配時損傷密封件。在有銳邊和溝槽的部位裝配密封圈時,要使用保護套,以免損傷密封件。設置液壓管路時應該使油箱到執(zhí)行機構(gòu)之間的距離盡可能短,管路的彎頭、特別是90°的彎頭要盡可能少,以減少壓力損失和摩擦。固定升降機液壓系統(tǒng)中應盡量減少管接頭,系統(tǒng)漏油有30%~40%是由管接頭漏出的。
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、控制固定升降機液壓系統(tǒng)溫度的升高,一般從油箱的設計和液壓管道的設置方面著手。為了提髙油箱的散熱效果,可以增加油箱的散熱表面,把油箱內(nèi)部的出油和回油用隔板隔開。油箱液壓油的溫度一般允許在55~65℃之間,最高不得超過70℃。當自然冷卻的油溫超過允許值時,就需要在油箱內(nèi)部增加冷卻水管或在回油路上設置冷卻器,以降低液壓油的溫度。
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、選擇合適固定升降機http://m.kkwl.net/結(jié)構(gòu)的液壓元件和管接頭,應根據(jù)工作可靠性和經(jīng)濟性進行選擇。
Select the appropriate structure fixed lift hydraulic components and fittings, should be selected according to reliability and economy.
