挖沙船液压系统应该如何保养
挖沙船液压系统应该如何保养,在这里给大家介绍下液压系统维护保养须知:

1、挖沙船液压系统运行前仔细检查系统是否漏油、连接是否松动、活塞杆和液压胶管是不是有撞伤、液压泵在低压进油时油管的连接是不是牢固可靠、油箱的油位是不是正确标准、所有动力机构主电磁阀门是不是处于最原始状态等,确保液压系统还有机械设备处在良好状态下。常压式油箱还需要检查并且清洁油箱通气孔,保持其畅通,可以防止由于气孔的堵塞而造成的油箱真空现象,从而导致液压油泵吸油困难而损坏等。

2、挖沙船液压系统运行中的巡回检查定期检查管路和元件之间的街头及密封装置失效的密封装置应该及时的进行更换,管接头以及各种合面的螺栓需要拧紧。通过看、闻、听、摸等方式方法,时常检查系统以及各种设备的运行的状况,出现噪声、压力波动、泄漏、振动等异常现象,应该立即分析查找原因并进行及时的处理,以消除安全隐患。
3、尤其要时刻注意液压泵和溢流阀的声音,如果是液压泵出现气蚀的噪音,经过排气之后不能消除,应该查明原因进行排除故障之后才可以使用。如果哪一个执行零部件在没有负荷时动作缓慢,并且伴有溢流阀溢流声响,应该立即停机检修等。

4、挖沙船液压系统的日常维护保养严格按照设备维护保养说明书的要求,及时更换易损耗易老化的耐油橡皮圈、滤芯等,减少管路泄漏防止失压;经常活络执行机构的运动部件,防止生锈减少运行阻力;定期用同牌号的液压油对管路、油箱、滤清器等进行清洗。

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.
