液壓啟閉機油箱內(nèi)的液壓油應始終保持正常油面
The hydraulic oil in the oil tank of the hydraulic hoist should always maintain a normal oil level
當管道和氣缸的容量很大時，應首先放入足夠的油。啟動后，由于油進入管道和氣缸，油面會下降，甚至濾油器會暴露油面，因此必須再次補充油。在使用過程中，也會發(fā)生泄漏，應在油箱上設(shè)置液面計，以便經(jīng)常觀察和補充油。
When the capacity of pipelines and cylinders is large, sufficient oil should be added first. After starting, due to the oil entering the pipelines and cylinders, the oil level will drop, and even the oil filter will expose the oil level, so it is necessary to replenish the oil again. During use, leaks may also occur, and a liquid level gauge should be installed on the fuel tank for frequent observation and replenishment of oil.
(2)使用室外液壓裝置時注意事項
(2) Precautions when using outdoor hydraulic devices
①隨著季節(jié)的不同，室外溫度變化劇烈，所以盡量使用粘度指數(shù)高的油。
① As the seasons change, outdoor temperature changes dramatically, so try to use oil with a high viscosity index.
②由于溫度變化，液壓系統(tǒng)油箱中的水蒸氣會凝結(jié)成水滴。冬季應每周檢查一次，發(fā)現(xiàn)后應立即清除。
② Due to temperature changes, the water vapor in the hydraulic system oil tank will condense into water droplets. In winter, it should be checked once a week and immediately removed if found.
③在屋外，因為臟物容易進入油中，所以要經(jīng)常換油。
③ Outside the house, it is necessary to change the oil frequently because dirt easily gets into the oil.

(3)首次啟動油泵的注意事項
(3) Precautions for starting the oil pump for the first time
①向泵內(nèi)灌滿油。
① Fill the pump with oil.
②檢查旋轉(zhuǎn)方向是否正確。
② Check if the rotation direction is correct.
③入口和出口是否裝反。
③ Is the inlet and outlet installed upside down.
④用手試轉(zhuǎn)。
④ Try turning by hand.
⑤檢查吸入側(cè)是否漏入空氣。
⑤ Check for air leakage on the suction side.
⑥在規(guī)定的速度啟動和運行。
⑥ Start and run at the specified speed.
(4)低溫下啟動油泵的注意事項
(4) Precautions for starting oil pumps at low temperatures
①在寒冷地區(qū)或冬季啟動油泵時，應打開、停止、往復幾次，使油溫升高。油壓裝置靈活運行后，進入正式運行。
① When starting the oil pump in cold regions or winter, it should be turned on, stopped, and reciprocated several times to increase the oil temperature. After the oil pressure device operates flexibly, it enters formal operation.
