[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figures 1 to 6 , this novel invention provides a technical solution:

[0031] A fuel pump housing compression test bench comprises a bottom plate 1, a detection assembly 2 is arranged on the top of the bottom plate 1, a fixing assembly 3 is arranged below the detection assembly 2, and a drainage assembly 4 is arranged at the bottom of the detection assembly 2;

[0032] The detection component 2 includes a tempered glass box 201, a fixing seat 202, a booster pump 203, an air pipe 204, a fuel pump 205 and an air pressure valve 206. The tempered glass box 201 is arranged on the top of the bottom plate 1, the fixing seat 202 is arranged on the top of a side wall of the tempered glass box 201, the booster pump 203 is arranged on the top of the fixing seat 202, the air pipe 204 is arranged on one side of the fixing seat 202, the fuel pump 205 is bolted to the bottom of the air pipe 204, and the air pressure valve 206 is arranged on one side of the air pipe 204.

[0033] Specifically, Figure 3 As shown, the drainage component 4 includes a drainage port 401 , a drainage valve 402 and a drainage pipe 403 . The drainage port 401 is arranged at the bottom of the tempered glass box 201 , the drainage valve 402 is arranged at the bottom of the drainage port 401 , and the drainage pipe 403 is arranged at the bottom of the drainage valve 402 .

[0034] Specifically, Figure 4 As shown, a waterproof lamp 9 is provided at the bottom of the tempered glass box 201 , and the waterproof lamp 9 is located on both sides of the fixing seat 202 .

[0035] The fuel pump 205 is placed inside the tempered glass box 201 through the fixing base 202. At this time, the fixing base 202 supports the fuel pump 205. One end of the fuel pump 205 is connected to the air pipe 204. At this time, the booster pump 203 increases the air pressure inside the fuel pump 205 through the air pipe 204. At this time, the air pressure valve 206 can monitor the air pressure state in the air pipe 204 in real time. Once the internal air pressure of the fuel pump 205 is too high, cracks and gaps will appear on the surface of the fuel pump 205. At this time, the gas leakage in the fuel pump 205 will cause bubbles to appear in the water inside the tempered glass box 201. The state of the cracks and gaps on the surface of the fuel pump 205 can be visually observed. At this time, the pressure resistance of the fuel pump 205 can be tested. After the test is completed, the drain valve 402 is opened. At this time, the water in the tempered glass box 201 is discharged from the drain port 401 and the drain pipe 403. At this time, the waterproof lamp 9 can provide light to the inside of the tempered glass box 201, so that the bubbles generated when cracks appear in the fuel pump 205 are more obvious.

[0036] Specifically, Figure 5 As shown, the fixing assembly 3 includes a base 301, a support pad 302 and a restraining belt 303. The base 301 is arranged at the inner bottom of the tempered glass box 201, the support pad 302 is arranged at the top of the base 301, the restraining belt 303 is fastened to the inside of the base 301, the fuel pump 205 is located at the top of the base 301, and the restraining belt 303 is located at the top of the fuel pump 205.

[0037] Specifically, Figure 1 As shown, an auxiliary frame 5 is disposed on the top of the bottom plate 1 , an auxiliary ring 6 is disposed on one side of the auxiliary frame 5 , and the auxiliary ring 6 is sleeved on one side of the auxiliary frame 5 .

[0038] When the fuel pump 205 is placed on the base 301, the auxiliary frame 5 supports one side of the boost pump 203, and the auxiliary ring 6 fixes the fuel pump 205 to prevent the boost pump 203 from shaking during operation.

[0039] Specifically, Figure 6 As shown, a shielding cover 7 is disposed on the top of the tempered glass box 201 , an insertion rod 8 is disposed on the bottom of the shielding cover 7 , and the bottom of the insertion rod 8 is clamped on the top of the tempered glass box 201 .

[0040] Specifically, Figure 6 As shown, a gripping handle 10 for lifting the shielding cover 7 is provided on the top of the shielding cover 7 .

[0041] The shielding cover 7 prevents dust and dirt from falling into the interior of the tempered glass box 201. At this time, the insertion rod 8 enters the side wall of the tempered glass box 201, and the shielding cover 7 is easily picked up by holding the handle 10.

[0042] Specifically, Figure 2 As shown, a support column 11 for supporting the bottom plate 1 is provided at the bottom of the bottom plate 1, and the material of the support column 11 is 310 stainless steel.

[0043] The base plate 1 can be supported by providing support columns 11 .

[0044] By adopting the above technical solution, the problem that the interior of the existing fuel pump 205 can be inspected but whether there is a gap on the internal high-pressure surface of the fuel pump 205 cannot be observed in real time is solved.

[0045] Working principle: When the present application is used, first, the fixing base 202 is placed inside the tempered glass box 201. At this time, the fixing base 202 supports the fuel pump 205. One end of the fuel pump 205 is connected to the air pipe 204. At this time, the booster pump 203 increases the air pressure inside the fuel pump 205 through the air pipe 204. At this time, the air pressure valve 206 can monitor the air pressure state in the air pipe 204 in real time. Once the internal air pressure of the fuel pump 205 is too high, cracks and gaps appear on the surface of the fuel pump 205. When the gas in the fuel pump 205 leaks, bubbles appear in the water inside the tempered glass box 201. The state of the cracks and gaps on the surface of the fuel pump 205 can be visually observed. At this time, the pressure resistance of the fuel pump 205 can be tested. After the test is completed, the drain valve 402 is opened. At this time, the water in the tempered glass box 201 is discharged from the drain port 401 and the drain pipe 403. At this time, the waterproof lamp 9 can provide light to the inside of the tempered glass box 201, so that the bubbles generated when cracks appear in the fuel pump 205 are more obvious.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
