在工程机械发动机的修理工作中,气缸盖泄漏的检测很重要。现以小松D375型推土机所用柴油机为例,介绍改进前、后的气缸盖泄漏检测方法如下。 1.早期的检测方法及其弊端 小松D375型推土机所用柴油机,其气缸盖为单体式气缸盖。对缸盖的检测工具是根据该缸气缸垫的模式设计的;加工了一个如图1所示的气缸盖底板,因为要用气缸垫进行密封,为保证密封效果,要求所加工的气缸盖底板的平面精度高;原气缸垫在检测时
In the construction machinery engine repair work, the cylinder head leak detection is very important. Now with the Komatsu D375 bulldozers used in diesel engines, for example, introduced before and after the improvement of cylinder head leak detection methods are as follows. 1. Early detection methods and their shortcomings Komatsu D375 bulldozers used in diesel engine, the cylinder head is a single cylinder head. Cylinder head detection tool is designed according to the cylinder head gasket model; Machined a cylinder head shown in Figure 1, because the cylinder head gasket to be sealed, in order to ensure the sealing effect, the cylinder head required processing The plane of high precision; the original cylinder gasket in the test
