With the continuous increase of rural and urban construction in China, excavators, bulldozers and other mechanical equipment have become common earthmoving machinery in construction site. These machines are used for a wide range of purposes, including mining and transportation. In addition to its powerful functions, excavators are also closely related to various excavator accessories.

　　挖掘机工作部分起着非常重要的作用,液压马达,液压马达挖掘机配件在使用时你应该更多的关注,因为有时泄漏液压马达,一旦泄漏的状态,然后就可以开始频繁的发生,这将大大影响挖掘机的正常工作,所以每个人都应该小心检查挖掘机配件液压马达。下面是对挖掘机液压马达频繁泄漏的原因及排除方法的总结，希望对您有所帮助。

　　The working part of excavator plays a very important role. You should pay more attention to hydraulic motors and excavator accessories when they are in use, because sometimes the leakage of hydraulic motors can occur frequently once the leakage state occurs, which will greatly affect the normal work of excavator, so everyone should carefully check the hydraulic motors of excavator accessories. The following is a summary of the reasons for frequent leakage of excavator hydraulic motors and the ways to eliminate it. I hope it will be helpful to you.

　　1. 挖掘机附件液压马达泄漏原因:

　　1. Reasons for leakage of hydraulic motor in excavator accessories:

　　1. 挖掘机配件配流板(配流孔)的磨损或应变，以及柱塞孔和柱塞的磨损，导致高低压空腔之间密封不良，工作腔内难以形成高压，导致进油不足。

　　1. The abrasion or strain of the valve plate (orifice) of the excavator fittings and the abrasion of the plunger orifice and plunger lead to poor sealing between the high and low pressure cavities, which makes it difficult to form high pressure in the working chamber and leads to insufficient oil intake.

　　2. 泄漏量与电机进出口压差、油粘度、排量、流量分布结构、加工装配质量等有关。泄漏量不稳定会导致电机转速不稳定、抖动或在不同时间停止。

　　2. Leakage is related to the differential pressure between the motor inlet and outlet, oil viscosity, displacement, flow distribution structure, processing and assembly quality, etc. Leakage instability can lead to motor speed instability, jitter or stop at different times.

　　3.排水管道回油差导致低压油压增加，导致骨架油封密封效果下降，推土机附件电机输出轴端漏油到减速机壳(或制动器)。

　　3. The return oil difference of drainage pipe leads to the increase of low pressure oil pressure, which leads to the decrease of sealing effect of skeleton oil seal, and the oil leakage from the output shaft end of the motor of bulldozer accessories to the reducer housing (or brake).

　　4、挖掘机附件电机输出轴支承轴承损坏，偏心泄漏，异常噪声;内部放电会导致电机锁定制动性能下降，不能在一定位置准确停车，会导致挖掘机产生打滑，非常不。

　　4. The bearing of the output shaft of the motor attached to excavator is damaged, eccentric leakage and abnormal noise. Internal discharge will lead to the deterioration of the lock-in braking performance of the motor and the inaccurate parking at a certain position, which will lead to slippage of the excavator, which is very unsafe.

　　King II. Excavator accessory hydraulic motor leakage troubleshooting method:

　　1. 检查挖掘机附件油轴或缸体孔内表面是否划伤。先清洗干净，如果是严重的，再更换。

　　1. Check for scratches on the inner surface of the oil axle or cylinder bore of excavator accessories. Clean it first and replace it if it's serious.

　　2. 如果挖掘机附件的柱塞配合面和柱塞孔上有沟槽或沟槽，则对配合面进行研磨或抛光后再研磨。如果情况严重，更换它。

　　2. If there are grooves or grooves on the plunger mating surface and plunger hole of excavator accessories, the mating surface will be ground or polished before grinding. If the situation is serious, replace it.

　　3.检查柱塞与柱塞孔配合面间隙是否过大(通常小于柱塞直径的8‰)，必要时更换。

　　3. Check whether the clearance between the plunger and the plunger hole is too large (usually less than 8_of the plunger diameter), and replace it if necessary.

　　4. 高速电机的漏失可以通过检测电机的漏油管，在空转和加载时分别测量壳体单位时间的漏油量来确定故障程度。

　　4. The leakage of the high-speed motor can be determined by detecting the leakage pipe of the motor and measuring the oil leakage per unit time of the shell during idling and loading respectively.
