在喷油器试验器上调试喷油器时常遇到以下问题: (1)试验器上的高压油管与喷油器接头密封不严而漏油。原因是喷油器接头凹锥或试验器上高压油管的凸锥经多次使用压紧而变形。排除方法:联接时,在它们之间夹一块塑料片并拧紧。 (2)更换新的喷油嘴偶件后,压力调不上去;或压力虽然调上去了,但雾化达不到要求;或喷油嘴偶件有漏油现象。原因可能是:喷油嘴偶件内防锈油未清洗干净造成密封不严或堵塞;偶件顶杆凹坑损坏或钢球丢失。排除方法:如果是前一个原因,可将喷油
In the injector tester on the injector often encounter the following problems: (1) tester on the high-pressure tubing and injector joints tight and leak. The reason is that the convex cone of the injector connector or the convex cone of the high-pressure tubing on the tester is deformed by multiple uses of pressing. Remedy: When coupling, clip a piece of plastic between them and tighten. (2) After the replacement of a new nozzle couple, the pressure can not go up; or adjust the pressure though up, but not meet the requirements of atomization; or nozzle spillage phenomenon. The reason may be: Inconsistent anti-rust oil nozzle even if the oil seal is not clean or blockage caused by sealing; even ejector pit damage or ball lost. Remedy: If it is the previous reason, you can inject fuel
