如果遼寧升降機使用的時間過長，液壓系統(tǒng)就會有所堵塞，造成設備升降速度過慢，有的時候可能不能升降，所以定時的清理液壓系統(tǒng)很重要，那么我們應該如何清理液壓系統(tǒng)呢？下面為就大家詳細講述清理的方法和步驟。If the Liaoning elevator use time is too long, the hydraulic system will be blocked, resulting in equipment lifting speed is too slow, sometimes may not be able to lift, so cleaning hydraulic system timing is very important, so we should how to clean up the hydraulic system? Here are the details about the cleaning methods and procedures.

1.選擇清洗油：當系統(tǒng)管路、油箱較干凈時，可選用與工作油液相同黏度的清洗油；如系統(tǒng)內不干凈，可選用黏度稍低的清洗油清洗。清洗油應與系統(tǒng)工作介質、所有密封件的材質相容。Choice of cleaning oil: when the system pipeline, the fuel tank is clean, can be used to work with the same viscosity of the oil liquid cleaning oil, such as the system is not clean, can use a slightly lower viscosity of the cleaning oil. Cleaning oil should be compatible with the working medium of the system, the material of all seals.

2.加熱清洗油：熱油能使系統(tǒng)內附著物容易游離脫落，一般需加熱至50～60℃，清洗壓力為0.1～0.2MPa，清洗油流量應盡可能大些，以利于帶走污物。Heating oil: oil cleaning system can be easily attached material free fall, generally need to be heated to 50 to 60 DEG C, cleaning pressure is 0.1 ~ 0.2MPa, the cleaning of oil flow should be as large as possible, in order to take away the dirt.

3.安裝遼寧升降機濾油器：在清洗回路中，進油口安裝50～100m的粗濾油器，回油口安裝10～50m的精濾油器。開始時粗濾，沖洗一段時間后逐步改用網(wǎng)眼細的濾油器，進行分次過濾。Installation of Liaoning elevator filter: in the cleaning circuit, the oil inlet to install 50 ~ 100m of the crude oil filter, oil return to install 10 ~ 50m of the refined oil filter. At the beginning of coarse filter, a period of time after washing and gradually replaced by oil filter mesh fine, for filtering.

4.應使液壓泵間歇運轉：為使清洗效果好，應使液壓泵轉轉、停停。在清洗過程中應用木錘輕輕敲擊油管數(shù)次，以促使污物盡快脫落，管路的彎曲和焊接部位要多錘擊，但不可用力過猛，以防損壞油管，錘擊時間占清洗時間的15％。The hydraulic pump intermittent operation: to make good cleaning effect, should make the hydraulic pump stop, stop. Application of wooden hammer tapping oil several times in the cleaning process, in order to promote as soon as possible dirt shedding, bending and welding line to hammer, but not overexert, in order to prevent damage to the tubing, hammer time cleaning time 15%.

5.確保清洗液流動為紊流狀態(tài)：為了有效的清洗，清洗液流動必須成為紊流狀態(tài)，即保證雷諾數(shù)在4 000以上才能確保清洗效果好；否則，清洗液應增加流量，升高溫度，降低黏度。小流量室溫下清洗，一般效果較差。To ensure that the cleaning fluid is turbulent flow state: for effective cleaning, cleaning fluid flow must become turbulent state, which is to ensure the Reynolds number to ensure good cleaning effect in more than 4000; otherwise, the cleaning liquid should increase the flow, temperature, viscosity reducing. Small flow at room temperature, the general effect is poor.

6.排凈清洗油：清洗終了應將清洗油排除干凈，包括泵、閥、管路及油冷卻器內存油，可松開管路排油后并用壓縮空氣吹掃，或加入工作油液帶走清洗油。Drain cleaning oil: end cleaning cleaning oil should be removed, including pump, valve, pipeline and oil cooler oil can loosen the line memory, drain and blow out with compressed air, or adding oil cleaning oil away.

7.遼寧升降機加入液壓油：排凈清洗油后，應盡快加入液壓油并進行短時間試運轉，以防管路銹蝕等。Liaoning elevator to join the hydraulic oil: after cleaning oil, the hydraulic oil should be added as soon as possible and carry out a short test run, in case of pipeline corrosion and so on.
