喷油器针阀偶件因长期处于高温高压的恶劣条件下工作，常回出现针阀被卡死在阀体内的故障，严重者甚至因此而报废。即使该偶件下可以修复，也费工费时，而且还不能充分保证其修复后的工作质量。有经验的机手和维修人员在生产实践中总结出５条小经验，可以有效的预防针阀偶件被烧结而卡死。 （１）在维修喷油器时，应将全部零件分解后认真清洗。不可只清洗针阀偶件，而将调压弹簧、弹簧螺母、调整螺钉及挺杆等零件置之不管。若这些零件上粘附的污染物不能xx，将会通过挺杆窜至针阀上部，在针阀运动时窜入针阀体和针阀之间将针阀卡死。 （２）不可拆除喷油器的回油管。回油管将工作中从针阀与阀体合面间渗漏出来的柴油密闭地引回低压油路，既避免了浪费，又保证了燃油清洁。若将回油管拆除，不仅渗出的柴油得不到再利用，而且空气中的沙尘微粒还会通过回油管与喷油器的连接孔道进入喷油器内，容易导致针阀卡死。有人在拆除回油管后将喷油器上的回油孔堵死，此法更不可取。因为当针阀偶件渗漏出的柴油溢满起上腔室后，其油压不短声高，最终将导致针阀偶件无法工作，并被烧结在一起。 （３）在维修发动机后安装高压油管说，要先将低压油路连接好，再将高压油管接向喷油泵，然后将油门手柄置于{zd0}供油位置，摇转曲轴，使喷油泵供油，直到高压油管出油端喷油5-10次后，再将高压油管出油端与喷油器相连。这样做，可将积存在高压油管内和喷油泵出油接头上发污物冲洗出去，避免污物随高压油进入喷油器而将针阀卡死。 （４）高压油管两端与喷油泵，喷油器项链的接头漏油时，不可采取垫铅丝，石棉线等方法来实施堵漏。可用薄铜皮剪成相应大小的圆垫，在圆垫中间冲一小孔，垫在高压油管接头处。因为铅丝和石棉线易被挤成碎末，随高压油管内的油流入喷油器，引起针阀卡死。 （５）有的柴油机在高压油管出油端装有针式滤芯，该滤芯过滤柴油中杂志的效果很好。有人在维修喷油器时将其拆下不装，这是十分错误的。该绿心不仅不应拆下不装，而且还应定期清洗。

Injector needle coupling of high temperature and pressure for a long period of work under harsh conditions, often return to there needle was stuck in the valve body failure, serious or even be scrapped. Even if the dual parts may be repaired, but also a lot of work and time-consuming, but also can not fully guarantee the quality of work after the repair. Experienced hand and machine maintenance personnel in the production practice summed up five little experience, can effectively prevent needle even pieces are sintered and choked to death. (1) in the maintenance of injectors, should, after careful cleaning all the parts break down. Couples should not only clean needle, but will pressure regulator spring, spring nut, screw, and other parts set tappet of the matter. If these components on the adhesion of contaminants can not be removed, will be through the needle valve tappet sneaked into the upper part of the needle movement fleeing into needle between the needle body and needle valve stuck. (2) can not be removed injector return pipe. Back to the pipeline would work together from the needle and valve surface between the diesel fuel leaking out of a confined low-pressure oil lineto lure back not only to avoid waste, but also to ensure clean fuel. Ruoqiang return pipe removed, not only are not re-use of diesel fuel leaking, but the air of dust particles will be passed back to the connection pipe and the injection into the injector inside the pore, may easily lead to needle stuck. It was the dismantling of fuel injector return pipe will block the hole on the back of this method is more desirable. Because when the needle out of dual pieces of diesel fuel leaking from the overflow chamber, its oil pressure not less than a high voice, will ultimately lead to needle Couples unable to work, and are sintered together. (3) in the maintenance of the engine after the installation of high-pressure tubing, said first low-pressure oil line will be connected, and then high-pressure pipeline next to the fuel pump, and then placed in the largest oil throttle handle position, shaking turn the crankshaft, so that fuel pump oil , until the high-pressure fuel injection pipe out of the oil-side 5-10 times, then out of the oil-side with the high-pressure fuel injection pipe is connected. This can be accumulated in the high-pressure tubing and the injection pump out the oil inside the connector on the fat flush out dirt to avoid contamination with the high-pressure oil into the injector and the needle stuck. (4) high-pressure tubing at both ends with the fuel pump, fuel injector connector oil spill necklace when you can not take mat wire, asbestos wire and other methods to implement the plugging. Available thin copper cut the size of the corresponding circular pad in the middle of a round pad washed a small hole, the mat in the high-pressure oil pipe joint office. Because the wire and asbestos-line easily Jichengsuimo, with the high-pressure tubing into the oil within the injector, causing needle stuck. (5) Some diesel engine out of oil at high pressure tubing with needle-side filter, the filter diesel filter works well in the magazine. Some people in the maintenance be removed when the injector is not installed, it is very wrong. The Green Heart should be removed not only do not install, but also the regular cleaning.
