Description

Technical Field

[0001] The utility model belongs to the technical field of diesel pump installation, and in particular relates to a diesel pump installation structure for special vehicles. Background Art

[0002] The traditional method of installing a diesel pump is to bolt it to the fuel tank. This method has the disadvantage that the weight of the diesel pump affects the tank structure. Mounting it on the tank creates a significant load and bending moment, which can cause deformation, cracking, and leaks. This inconveniences maintenance and poses safety risks. Furthermore, the diesel pump's installation takes up space in the tank, reducing the amount of fuel and impacting the vehicle's maximum range. Utility Model Content

[0003] In response to the above technical problems, the present invention proposes a diesel pump mounting structure for special vehicles. This structure can separate the fuel pump from the fuel tank, and fix the diesel pump, retaining ring, rubber pad and base through stud nuts. This structure is then connected in series with the fuel system through pipelines. Under the premise of ensuring stable oil delivery, the volume of the fuel tank is maximized, the integrity of the fuel tank's own structure is guaranteed, and the risk of deformation and cracking is avoided. At the same time, the direction and angle of oil delivery can be adjusted arbitrarily according to different installation environments and installation angles, solving the difficulties in diesel pump installation. It is not restricted by the installation position of the fuel tank and does not damage the structure of the fuel tank. It provides a safe and reliable installation structure suitable for various special vehicles with fuel supply systems such as tanks, infantry fighting vehicles, and self-propelled artillery.

[0004] The technical solutions adopted in this utility model are as follows:

[0005] A diesel pump mounting structure for special vehicles consists of a retaining ring, a diesel pump, a rubber pad, a base, a nut, a stud and a locking washer. The stud is mounted on the base, and the diesel pump is mounted on the base via the stud and the nut. A rubber pad is installed between the diesel pump and the base, and the retaining ring is pressed onto the diesel pump via the nut and the locking washer.

[0006] Furthermore, the diesel pump is a metal electrical component with mounting holes evenly distributed on it. It can be fixed to the base with stud nuts. There is a wiring socket on the top for power supply, and a connecting pipe on the side that can stably and continuously deliver the diesel at the bottom inlet to the engine combustion chamber through the pipeline.

[0007] Furthermore, the retaining ring is a metal machined part with mounting holes evenly distributed thereon, the size distribution of which is consistent with the diesel pump mounting holes, and is used to press the diesel pump onto the mounting base and also protect the diesel pump mounting surface.

[0008] Furthermore, the rubber pad is made of oil-resistant asbestos rubber material and is evenly distributed with through holes. When installed, it is clamped between the diesel pump and the base to play a sealing role.

[0009] Furthermore, the base is a metal welded part, and the top flange is evenly distributed with threaded blind holes. The retaining ring, diesel pump and rubber gasket are installed together through studs and nuts. There is a connecting pipe on the side that can be connected to the fuel tank through a hose. The bottom closed base plate is evenly distributed with mounting holes, which can be installed on the vehicle with bolts.

[0010] The installation process of the above installation structure is as follows:

[0011] The stud is installed on the base, and then the rubber pad is pressed on the base. The diesel pump is then installed on the stud at a suitable oil delivery angle (the installation angle of the diesel pump and the base can be adjusted to adjust the direction of the inlet and outlet oil pipes to achieve different oil supply angles). Finally, the nut and the lock washer press the retaining ring onto the diesel pump, tighten the nut with a wrench, and adjust the lock washer to the active state to form an independent diesel pump installation structure.

[0012] The beneficial effects of the present invention are:

[0013] The diesel pump mounting structure of the present invention is an independent structure with high applicability. It can be installed in different positions according to different vehicle models. It does not rely on the fuel tank for installation, is not restricted by the fuel tank structure and installation space, does not destroy the structural integrity of the fuel tank itself, and does not affect the structural stability of the fuel tank itself. The size of the base mounting flange can be adjusted according to the different diesel pump mounting interface sizes to adapt to different fuel supply requirements. The mounting structure can adjust the direction of the inlet and outlet pipes by adjusting the installation angle of the diesel pump and the base, thereby achieving up to eight different fuel supply angles.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] like Figure 1-3 As shown in FIG, a diesel pump mounting structure for special vehicles includes a retaining ring 1, a diesel pump 2, a rubber pad 3, a base 4, a nut 5, a stud 6 and a locking washer 7, a total of seven components, such as Figure 4 As shown, the base includes a bottom plate 11, a cover plate 10, a flange 9, and a pipe 8. During installation, first use a wrench to install the stud 6 into the threaded hole at the top of the base 4. Then, pass the rubber pad 3 through the stud 6 and press it onto the flange 9 at the top of the base 4. Then, find the appropriate oil inlet and outlet angles and install the diesel pump 2 on the stud 6. Finally, use the nut 5 and the lock washer 7 to press the retaining ring 1 onto the diesel pump 2. Tighten the nut 5 with a wrench and adjust the lock washer 7 to the active state.

[0021] Preferably, the retaining ring 1 is a metal machined component with eight evenly spaced through-holes, each 7 mm in diameter, sized and distributed to match the mounting holes of the diesel pump 2. This serves to press the diesel pump 2 against the mounting base 4 and protect the mounting surface of the diesel pump 2. The diesel pump 2 is a metal electrical component with eight evenly spaced through-holes, each 7 mm in diameter. It is secured to the base 4 via studs 6 and nuts 5. A wiring socket is located on the top for power supply, and a side connection allows for a stable and continuous flow of diesel fuel from the bottom inlet to the engine combustion chamber via a pipeline. The rubber pad 3 is made of oil-resistant asbestos rubber and has eight evenly spaced through-holes, each 7 mm in diameter. During installation, it is sandwiched between the diesel pump 2 and the base 4 to provide a seal. The base 4 is a metal welded part. The top flange 9 of the base 4 is evenly distributed with 8 threaded blind holes. The retaining ring 1, diesel pump 2 and rubber pad 3 are installed together through studs 6 and nuts 5. There is a connecting pipe on the side that can be connected to the fuel tank through a hose. The oil delivery angle can be adjusted by adjusting the installation angle between the connecting pipe of the base 4 and the connecting pipe of the diesel pump 2. There are 6 mounting holes evenly distributed on the bottom closed base plate 11, which can be firmly fixed to any part of the vehicle through bolts and mounting brackets.
