喷油器针阀由于种种原因会出现卡死现象,直接影响柴油机的正常工作。咬死的喷油器偶件取出针阀后,经过研磨,可继续投入使用。过去,我们对于咬死的针阀取出方法不妥,致使针阀尾部部分折断。对一部分专用针阀,一旦折断又不易买到者常常影响工作。我们设计制造了一种简易喷油器针阀拉出器。如图所示。它能安全可靠地将针阀拉出。操作方法:卸掉蝶形螺母8、压板7,将针阀锁夹3、锁夹座组合4、压拉螺杆6一起抽出(这三个部件组装在一起,不需要拆开),再将压杆退出两 Needle valve injector for a variety of reasons there will be stuck phenomenon, a direct impact on the normal work of the diesel engine. After the biting of the injector to remove the needle valve, after grinding, can continue to put into use. In the past, we took the wrong way to take out the stitched needle valve, causing the tail part of the needle to break. On the part of the special needle valve, once broken and not easy to buy who often affect the work. We designed and manufactured a simple injector needle puller. as the picture shows. It safely and reliably pulls the needle valve out. Operation method: remove the wing nut 8, the pressure plate 7, the needle lock clamp 3, 4 lock clamp combination, pull the screw 6 together (these three components assembled together, do not need to open), then the pressure Rod exit two
