195柴油机缸盖上的涡流室镶块,使用中常发生松动或产生裂纹等现象,对此,采取以下方法解决。 1.松动卸下缸盖,认真查看镶块边缘和缸盖配合孔周围有无裂纹,同时检查相对配合位置是否转位。如没有裂纹,仅仅是相对转位、松动,可将缸盖放平,用冲头在镶块与缸盖配合孔周围冲上4～6个冲坑,即可使其紧固,继续使用。 2.裂纹镶块如有裂纹应及时更换。更换后,可在镶块与缸盖配合孔之间打一个直径0.4～0.6毫米、深3～5毫米的定位孔,装上定位销,防止其松动、转位以致产生裂纹。
195 Diesel engine cylinder head swirl chamber inserts, often occur in the use of loosening or crack, etc., in this regard, to take the following solution. 1. Loosen the cylinder head, carefully check the insert edge and cylinder head with or without cracks around the hole, while checking the relative position with the match. If there is no crack, just relatively relative indexing and loosening, the cylinder head can be leveled, punched in the insert block and the cylinder cover with a hole punched 4 ~ 6 red pit, you can make it fastened and continue to use. 2. Crack inserts if cracks should be promptly replaced. After replacement, insert a positioning hole with a diameter of 0.4 ~ 0.6 mm and a depth of 3 ~ 5 mm between the insert block and the cylinder head, and install a locating pin to prevent loosening and indexing so as to cause cracks.
