Excavator Editor today introduces the damage of poor quality injector to excavator.

　　喷油器是挖掘机的重要组成配件，发挥着较举足轻重的作用。假冒的喷油器加工精度较差，会造成雾化不良、滴油、卡滞等现象，造成发动机冒黑烟。加快了发动机机件早期的磨损，造成大的损失。

　　Injector is an important part of excavator and plays a more important role. The fake injector has poor processing accuracy, which will cause poor atomization, dropping oil, sticking and other phenomena, resulting in black smoke from the engine. It accelerates the early wear and tear of engine parts and causes great losses.

　　通过对伪劣挖掘机配件的介绍，相信各位消费者对挖掘机配件已经有了更深刻的认识。这些伪劣配件本身的价值相对都较低，但它们对设备整体的危害却是几十倍甚几百倍的。所以希望消费者在批发挖掘机配件的时候能够积极维护自身的权益，避免因小失大，坚决远离假冒品，选择***。

　　Through the introduction of fake and inferior excavator accessories, I believe that consumers have a deeper understanding of excavator accessories. The value of these fake and inferior parts is relatively low, but their harm to the whole equipment is tens or even hundreds of times. So I hope that consumers can actively safeguard their rights and interests when wholesale excavator accessories, avoid small losses, firmly away from counterfeit products, and choose genuine products.

　　回转式减速器是挖掘机液压配件回转系统的重要组成部分。是一种集成了驱动动力源的全周回转减速传动机构。下面挖掘机小编来介绍一下回转减速器。

　　Rotary reducer is an important part of rotary system of excavator hydraulic fittings. It is a kind of all-circumferential rotary deceleration transmission mechanism which integrates driving power source. The following excavator knitting to introduce the rotary reducer.

　　回转减速器的工作原理是以回转支承作为传动从动件和机构附着件，通过了在回转支承内外圈中的一个圈上附着主动件、驱动源和罩壳，而是把另一个圈既当作传动从动件，又能作为被驱动工作部件的连接基座，这样利用回转支承本身就是全周回转连接件的特点，配置驱动动力源与主传动零件，使它成为一种集回转、减速和驱动功能于一体而同时又结构简单，制造和维护方便的通用型减速传动机构。

　　The working principle of the rotary reducer is that the rotary bearing acts as the driving follower and the mechanism attachment. By attaching the active part, the driving source and the cover on one ring of the inner and outer rings of the rotary bearing, the other ring acts as both the driving follower and the connecting base of the driven working parts. Therefore, the use of the rotary bearing itself is the characteristic of the circumferential rotary connector. Effective allocation of driving power source and main transmission parts makes it a universal deceleration transmission mechanism with rotary, deceleration and driving functions, simple structure and convenient manufacture and maintenance.
