液壓統使用前要主要哪些事項?
1、使用者把握液壓系統的工作原理,認識各種控制機構的操縱特點和調整手柄的位置、旋向等。
2、開車前檢查油面,保證液壓系統有足夠的油液。按期檢查更換液壓油液,新設備使用三個月左右即應清洗油箱,更換油液,以后每隔半年至一年進行清洗和換油一次。加油時要過濾。
3、油箱應加蓋密封,油箱上面的通氣孔處設置空氣濾清器。
4、液壓系統中根據需要配置粗、精過濾器,并常常檢查、清洗和更換。
5、開車前應檢查各調整手柄、手輪的位置是否準確,電氣開關和行程開關的位置是否正常,主機上工具的安裝是否準確、牢固等,再對導軌和活塞桿外露部門進行擦拭,然后方可開車。
6、開車時,有專用控制油路液壓泵的,要先啟動該泵,再啟動主液壓泵。
7、當環境溫度較低、油液黏度較大時,應想法升高油溫。例如,采用點動方式反復啟動定量泵;減小變量泵斜盤傾角,啟動后空轉一段時間等。
8、有排氣裝置的液壓系統應進行排氣,無排氣裝置的液壓系統應先空載往復運動多次,使之天然排出氣體。
9、對壓力控制元件的調整,一般首先從溢流閥開始,使整個液壓系統的壓力從零逐步進步,終極達到劃定壓力值,然后依次調整各回路的壓力控制閥。
10、流量控制閥的調整,應使流量從小到大,逐步調整。同步運動執行元件的流量控制閥應同時調整。要保證運動平穩性。
11、工作中應隨時留意油液溫升,正常工作時,油箱中油液溫度應不超過60℃。
12、設備若長期不用,應將各手輪全部放松,以防彈簧產生永久變形而影響元件機能。

Before using the main hydraulic system to what matters ?
A user to grasp the hydraulic system works , understanding the manipulation of a variety of features and control mechanism to adjust the handle position , rotation, and so on. 2 , check the oil level before driving to ensure that there is enough oil in the hydraulic system . Regularly check and replace the hydraulic fluid , new equipment for three months or so that the tank should be cleaned , replace the oil after every six months to a year for cleaning and oil change once. To filter when refueling . 3 , the fuel tank should be affixed to the seal tank vent above set at the air filter. 4 , the hydraulic system needs to be configured according to coarse , fine filter , and often inspection, cleaning and replacement. 5, the car should be checked before each adjustment handle, hand wheel position is accurate, electrical switches and limit switch position is normal, whether the tools are installed on the host accurate , solid , etc. , and then exposed to the rail sector and the piston rod to wipe , and then before driving. 6 , when driving , a dedicated control circuit of the hydraulic pump , first start the pump , and then start the main hydraulic pump . 7 , when the ambient temperature is low , the oil viscosity is large, elevated oil temperature should be thinking . For example , using the jog mode starts repeated dosing pumps ; reduced variable pump swash plate angle , starts idling period of time. 8 , an exhaust system of the hydraulic system should be vented , no exhaust load of the hydraulic system should be reciprocated repeatedly , so that the natural exhaust gases. 9 , the adjustment of the pressure control element , generally the first starting from the relief valve , the pressure of the hydraulic system gradually progress from zero , the final pressure value reaches delineated , and each circuit in order to adjust the pressure control valve . 10 , the flow control valve adjustment , should the flow from small to large , and gradually adjust . Synchronous movement of the flow control valve actuator should also be adjusted. To ensure smooth movement . 11 , work should always pay attention to the oil temperature, normal working hours, the tank fluid temperature should not exceed 60 ℃. 12 , the device if the long-term need , should all relax the hand wheel to prevent permanent deformation of the spring elements affecting performance .
