升降貨梯作為貨物垂直升降的運輸設備，現如今已經(jīng)普及到社會(huì )生活的各個(gè)角落，使用越來(lái)越廣泛，不管是建筑，土木工程，還是日常生活中安裝和維修都離不開(kāi)貨梯的使用。     液壓系統是升降貨梯機械重要組成部分，液壓油進(jìn)入液壓系統運行之時(shí)，清潔就是首要問(wèn)題。應阻止臟物和其它雜質(zhì)進(jìn)入系統。正如你已知道的，微小粒子會(huì )擦傷閥門(mén)，卡住泵，阻塞孔口，從而造成耗費財力的修理。     維護好液壓系統是關(guān)系到升降貨梯機械的安全使用和長(cháng)久使用的關(guān)鍵，如何正確掌握液壓系統維護的方法呢？ 如何保持液壓系統清潔？

一、 液壓升降貨梯要保持液壓油清潔

The hydraulic elevator should keep the hydraulic oil clean

將油儲存在清潔位置，換油或加油時(shí)必須小心謹慎。只能使用配備細格濾網(wǎng)的清潔漏斗將油從容器倒入油箱。當然，你使用的油必須應該是設備生產(chǎn)商推薦的類(lèi)型。

Store oil in a clean place, and be careful when changing oil or refueling. The oil can only be poured from the container into the tank using a clean funnel equipped with a fine mesh filter. Of course, the oil you use must be the type recommended by the device manufacturer.

二、貨梯要保持系統清潔

The elevator should keep the system clean

定期更換油和過(guò)濾器。好的液壓油含有多種添加劑，這些添加劑可防止油變質(zhì)或堵塞系統零件。但是，這些添加劑在一段時(shí)間以后會(huì )喪失效用。因此油應該定期更換，確保添加劑發(fā)揮作用。過(guò)濾器只能從油中吸收有限數量的污垢粒子和其它雜質(zhì)。按建議的周期更換過(guò)濾器，以便保持系統清潔。

Change oil and filter regularly. Good hydraulic oil contains a variety of additives that prevent oil deterioration or block system parts. However, these additives will be ineffective over time. The oil should be replaced periodically to ensure that the additives are used. Filters can only absorb a limited amount of dirt and other impurities from oil. Replace the filter with recommended cycles to keep the system clean.

三、貨梯要定期放油和重新加油

Third, the ladder should be oil and refuel regularly

定期放出油箱中的水和沉淀物，對于清除油中雜質(zhì)十分重要，但是定期放空整個(gè)液壓系統也十分重要。這是完全清除系統雜質(zhì)、被氧化的液壓油和其它有害物質(zhì)的唯一可靠的方法。然后，應該將推薦的清潔的液壓油重新加入系統之中。

Regularly releasing water and sediment in the tank is important for removing impurities in the oil, but it is also important to regularly empty the entire hydraulic system. This is the only reliable way to completely remove the impurities of the system, the hydraulic oil and other harmful substances that are oxidized. The recommended clean hydraulic oil should then be added to the system.

如果導軌升降貨梯的液壓油已完全污染，特別當泵受到損壞時(shí)，必須清洗油箱中的油。通過(guò)油清洗裝置使油流動(dòng)，直至油污染指標顯示，油已處于令人滿(mǎn)意的狀態(tài)。

If the hydraulic oil of the guide elevator is completely polluted, especially when the pump is damaged, the oil in the tank must be cleaned. The oil is flowing through the oil cleaning device until the oil pollution indicator shows that the oil is in satisfactory condition.
