    挖沙船液壓系統應該如何保養
    挖沙船液壓系統應該如何保養,在這里給大家介紹下液壓系統維護保養須知:

    1、挖沙船液壓系統運行前仔細檢查系統是否漏油、連接是否松動、活塞桿和液壓膠管是不是有撞傷、液壓泵在低壓進油時油管的連接是不是牢固可靠、油箱的油位是不是正確標準、所有動力機構主電磁閥門是不是處于最原始狀態等,確保液壓系統還有機械設備處在良好狀態下。常壓式油箱還需要檢查并且清潔油箱通氣孔,保持其暢通,可以防止由于氣孔的堵塞而造成的油箱真空現象,從而導致液壓油泵吸油困難而損壞等。

    2、挖沙船液壓系統運行中的巡回檢查定期檢查管路和元件之間的街頭及密封裝置失效的密封裝置應該及時的進行更換,管接頭以及各種合面的螺栓需要擰緊。通過看、聞、聽、摸等方式方法,時常檢查系統以及各種設備的運行的狀況,出現噪聲、壓力波動、泄漏、振動等異?,F象,應該立即分析查找原因并進行及時的處理,以消除安全隱患。
    3、尤其要時刻注意液壓泵和溢流閥的聲音,如果是液壓泵出現氣蝕的噪音,經過排氣之后不能消除,應該查明原因進行排除故障之后才可以使用。如果哪一個執行零部件在沒有負荷時動作緩慢,并且伴有溢流閥溢流聲響,應該立即停機檢修等。

    4、挖沙船液壓系統的日常維護保養嚴格按照設備維護保養說明書的要求,及時更換易損耗易老化的耐油橡皮圈、濾芯等,減少管路泄漏防止失壓;經?;罱j執行機構的運動部件,防止生銹減少運行阻力;定期用同牌號的液壓油對管路、油箱、濾清器等進行清洗。

    Dredging hydraulic system should be how to maintain, here to introduce the hydraulic system maintenance Instructions:
    1, dredge hydraulic system before the operation of carefully check whether the system leaks oil, the connection is loose, piston rod and hydraulic hose is not a collision, hydraulic pump in the low-pressure oil when the connection is not a solid reliable, oil tank is not the correct standard, all the main power mechanism solenoid valve is not in the most original state, to ensure that the hydraulic system and mechanical equipment in good condition. Atmospheric pressure tank also need to check and clean the gas tank vent, keep it unblocked, can prevent the blockage of the gas tank caused by the vacuum phenomenon, resulting in hydraulic oil pump oil difficulties and damage, etc.
    2, dredge hydraulic system operation of the circuit inspection regularly check the pipeline and components between the street and sealing device failure of the sealing device should be replaced in a timely manner, the fittings and all kinds of bolts need to tighten. Through watching, smelling, listening, touching and other methods, and often check the system and the operation of various equipment, noise, pressure fluctuations, leakage, vibration and other anomalies, should immediately analyze the cause and timely treatment to eliminate the hidden dangers.
    3, especially to pay attention to the hydraulic pump and overflow valve sound, if it is a hydraulic pump cavitation noise, after the exhaust can not be eliminated after the cause should be identified after troubleshooting can be used. If the execution of components in the absence of load slow movement, and accompanied by overflow valve overflow sound, should be immediately shut down and overhaul.
    4. The Daily maintenance and maintenance of hydraulic system of dredger is in strict accordance with the requirements of equipment maintenance manual, timely replacement of perishable oil-resistant rubber bands, filter elements, etc., to reduce the leakage of pipelines to prevent loss of pressure; regular movement of the actuator parts to prevent rust to reduce operating resistance; regular use of the same brand of hydraulic oil to the pipeline, fuel tank, filter, etc. to clean.
