Manually in the fixing device of exhaust pump, described linkage structure comprises several bolts on above-mentioned a kind of diesel engine, and described bolt can cooperate with the bolt hole on the car body bearing and car body are connected, and also is arranged with packing ring on the described bolt.Utilize bolt that bearing is fixed on the car body, prevent pump housing play.
On above-mentioned a kind of diesel engine manually in the fixing device of exhaust pump, as another kind of technological scheme, described linkage structure comprises that several are installed in buckle and the through hole that is arranged on the car body on the bearing lower end surface, and described buckle can be connected in the through hole.The manual exhaust pump can also be installed on the cooling fan on the car body, because cooling fan is plastic material, can better fix and simplified structure with the means of fixation of buckle.
In the fixing device of manual exhaust pump, described clip has two, can be connected to respectively the two ends of the pump housing on above-mentioned a kind of diesel engine.The two ends that two clips are connected to respectively the pump housing prevent pump housing play on bearing.
Compared with prior art, the utlity model has following advantage:
1, the manual exhaust pump utilizes clip to be fixed on the bearing, both can realize removably connecting, and also fixed.
2, can rotate two kinds of bearing means of fixation that this device provides according to the layout of installing space and engine compartment, make this device have preferably versatility.
