装载机漏油了怎么处理?

内容详情:
装载机主要是在矿井下作业的,在井下恶劣环境下持续工作很容易引起故障,包括我们常见的漏油问题。装载机漏油是比较严重的,危险系数比较大,特别是在恶劣条件下容易引发事故。那么,下面我们就来讲解一下该问题的处理方法。
The loader is mainly operated under the mine, and it is easy to cause failures when it continues to work under the harsh underground environment, including our common oil leakage problem. The oil leakage of loader is relatively serious, and the risk factor is relatively large, especially under adverse conditions, it is easy to cause safety accidents. Then, let's explain how to deal with this problem.
1、外泄漏故障的处理:外泄漏一般凭肉眼就可观察到。先检查防爆装载机的油管有无破裂,管接头是否松动,密封件是否损坏、失效或挤出;检查缸盖与缸筒的接合处,活塞杆与缸盖导向套之间有无泄漏现象,检查活塞杆刮伤情况。而在处理时可以采用紧固管座螺栓,更换密封件,活塞杆拉伤严重要重新镀铬处理或更换。
1. Treatment of leakage: leakage can be observed by naked eyes. First, check whether the oil pipe of the explosion-proof loader is broken, whether the pipe joint is loose, and whether the seal is damaged, invalid or extruded; Check whether there is leakage at the joint between the cylinder head and cylinder barrel, between the piston rod and the cylinder head guide sleeve, and check the scratch of the piston rod. During the treatment, the pipe seat bolts can be tightened and the seals can be replaced. If the piston rod is seriously strained, it should be re chrome plated or replaced.
2、内泄漏故障的处理:由于该部分内泄漏主要产生于动臂滑阀和油缸内泄漏。内泄漏隐藏于阀和缸内部,不易检查。但我们可以借助一些辅助方法来判断泄漏情。处理时先对动臂油缸进行检查,当动臂缸活塞收到底后,拆下无杆腔油管,使动臂缸有杆腔继续充油。若防爆装载机的无杆腔油口有大量工作油泄出,说明液压缸发生内漏。然后对动臂滑阀进行检查,动臂滑阀的泄漏主要是因为阀杆与阀体的配合间隙太大,调压弹簧损坏,阀内密封件损坏或阀体有砂眼等。
2. Treatment of internal leakage: the internal leakage of this part is mainly caused by the internal leakage of boom spool valve and cylinder. Internal leakage is hidden inside the valve and cylinder, which is difficult to check. However, we can use some auxiliary methods to judge the leakage. Check the boom cylinder before handling. When the boom cylinder piston is fully retracted, remove the oil pipe without rod chamber, so that the rod chamber of the boom cylinder continues to be filled with oil. If there is a large amount of working oil leaking from the oil port of the rodless chamber of the explosion-proof loader, it indicates that the hydraulic cylinder has internal leakage. Then check the boom spool valve. The leakage of the boom spool valve is mainly due to the large fit gap between the valve rod and the valve body, the damage of the pressure regulating spring, the damage of the seals in the valve or the sand holes in the valve body.
