Problems solved by technology
In general, the fatigue elongation of the pulley belt during use is not considered. Therefore, when the drive belt length adjustment mechanism is omitted and the device runs for a period of time, the slack of the belt will affect the working efficiency of the fuel pump, and even Affect the normal operation of the fuel pump
At the same time, due to the relatively large vibration during the working process of the car, the brittleness of the casting also makes the cracks of the bearings occur from time to time during the working process.

The invention relates to a fuel oil pump mounting device for a secondary engine. The device is used for mounting and regulating fuel oil pumps for secondary engines on various road sweepers. The fuel oil pump mounting device comprises a mounting supporting base which is formed by integrally welding a shaft base, a shaft base supporting plate, an oil pump supporting base and a seat plate assembly, wherein the fuel oil pump and a belt wheel shaft are fixedly arranged on the supporting base, and are connected through a shaft coupler; a belt wheel is fixedly arranged on the belt wheel shaft for transmitting power from the secondary engine to drive the fuel oil pump to operate; and regulation of a mounting position of the device is realized by a regulating base and regulating bolts. The mounting supporting base with a split type assembly welding structure of the device overcomes vibration brittle rupture, in a using process, of a cast piece, so that the weight of the supporting base is reduced; and meanwhile, when a belt wheel transmission belt generates stretching deformation in the using process, regulation on belt tension degree is realized by regulating the position of the mounting supporting base.
Description
Technical field [0001] The invention relates to a fuel pump installation device for supplying fuel to auxiliary engines of various road sweepers. The road sweeper is a special vehicle used for sanitation cleaning and cleaning operations, and the auxiliary engine on board provides power for the working device. Background technique [0002] When the road sweeper is working, the power of its working device comes from the auxiliary engine placed on the vehicle, and a special fuel pump is responsible for supplying oil to the auxiliary engine. The device is installed and fixed on the sub-frame, and is connected to the fuel tank and the sub-engine through pipelines. The common installation structure is to use castings as the support, including the use of couplings to connect the fuel pump shaft and the pulley shaft to achieve power transmission. The fuel pump and the pulley shaft are installed and fixed on the seat body, and the other end of the pulley shaft is connected to the pul...
