Description

Technical Field

[0001] This utility model belongs to the field of intake manifold testing technology, and in particular relates to a plastic intake manifold sealing testing device. Background Technology

[0002] The intake manifold refers to the intake piping from the carburetor or throttle body to the intake manifold of the cylinder head. Its function is to distribute the air-fuel mixture from the carburetor or throttle body to the intake manifolds of each cylinder. For port fuel injection engines or diesel engines, the intake manifold only distributes clean air to the intake manifolds of each cylinder. The intake manifold must distribute the air-fuel mixture or clean air to each cylinder as evenly as possible. To this end, the length of the gas flow passages inside the intake manifold should be as equal as possible. In order to reduce gas flow resistance and improve intake capacity, the inner wall of the intake manifold should be smooth. When processing plastic intake manifolds, a sealing test is required to ensure safe use.

[0003] In current methods for testing the sealing performance of plastic intake manifolds, the gas pressure is increased by inputting gas and observing whether there is any leakage. However, the waste generated during the processing of the intake manifold can easily adhere to the surface of the intake manifold, causing blockage of the tiny pores and affecting the accuracy of the intake manifold test. Utility Model Content

[0004] The purpose of this invention is to provide a plastic intake manifold sealing test device, which aims to solve the problem that existing plastic intake manifold sealing tests mostly involve increasing the pressure of the input gas and observing whether there is any leakage in the intake manifold. However, waste generated during the processing of the intake manifold is easily adsorbed on the surface of the intake manifold, causing blockage of the tiny pores and affecting the accuracy of the intake manifold test.

[0011] This utility model provides a plastic intake manifold sealing performance testing device.

The device includes a test body 1, a support assembly 2, a cleaning assembly 3, a cleaning assembly 5, and a separation assembly 6. The cleaning assembly 3 includes a water pump structure 31, a fixed water pipe 32 is fixedly connected to the end face of the water pump structure 31, a fixed pipe 33 is fixedly connected to the end face of the fixed water pipe 32, and a nozzle structure 34 is rotatably connected to the end face of the fixed pipe 33.

[0020] This utility model provides a plastic intake manifold sealing performance testing device. Through the cleaning component 3, the cleaning liquid inside the testing body 1 is circulated, thereby pressurizing and spraying the cleaning liquid onto the plastic intake manifold to clean impurities on its surface. Through the cleaning component 5 and the separation component 6, the plastic intake manifold can be completely immersed in the cleaning liquid to clean internal impurities. Due to the circulation of the cleaning liquid, the turbine structure 52 rotates, synchronously rotating the cleaning roller 53 to clean the plastic intake manifold, thus preventing impurities from clogging the plastic intake manifold and affecting the accuracy of the sealing performance test.

[0021] In this embodiment of the invention, during use, the plastic intake manifold is connected and fixed to the fixing rope 24. The electric telescopic column 22 is energized to move the intake manifold, energizing the water pump structure 31. The cleaning liquid inside the main body 1 is detected and sprayed out from the nozzle structure 34 through the fixing water pipe 32 and fixing pipe 33 to rinse the surface of the plastic intake manifold. Then, the height of the intake manifold is adjusted so that it is completely immersed in the cleaning liquid. The liquid flow rotates the turbine structure 52, causing the cleaning roller 53 to rotate and clean the surface of the intake manifold. The adsorbed impurities are effectively treated, and during liquid flow, the cleaned impurities are filtered through the adsorption filter plate 62 and the separation filter plate 63 to prevent impurities from clogging or re-contaminating the intake manifold. Afterward, the intake manifold is pulled up and the liquid is dried by the dryer 13. The mounting head 27 is connected to the intake manifold, and the different air outlets of the intake manifold are sealed and blocked. The air pump structure 25 is powered on to supply gas, and the intake manifold completely immersed in the liquid is observed to see if any air bubbles are generated, thereby testing its sealing performance.

An electric telescopic column 22 is fixedly connected to the end face of the mounting plate 21. A fixing plate 23 is installed on the end face of the electric telescopic column 22. A fixing rope 24 is fixedly connected to the end face of the fixing plate 23. An air pump structure 25 is fixedly connected to the free end of the fixing plate 23. A fixing hose 26 is fixedly connected to the end face of the air pump structure 25. An installation head 27 is fixedly connected to the end face of the fixing hose 26. The plastic intake manifold can be fixed and its height adjusted so that it is immersed in the cleaning liquid. Furthermore, the gas inside the dried plastic intake manifold can be discharged to test its sealing performance.

[0024] like Figure 2 and Figure 3As shown, in a further embodiment of this utility model, the free end of the water pump structure 31 is fixedly connected to the detection body 1, the outer wall of the fixed water pipe 32 is fixedly connected to the detection body 1, and the free end of the fixed pipe 33 is fixedly connected to the detection body 1; the force of the fixed pipe 33 can make the cleaning liquid inside the detection body 1 circulate, thereby avoiding the waste of cleaning liquid and saving the cost of testing the sealing performance of the plastic intake manifold.

[0025] like Figure 4 As shown, in a further embodiment of this utility model, the end face and free end of the cleaning shaft 51 are rotatably connected to the detection body 1, and the turbine structure 52 and the cleaning roller 53 are rotatably connected to the detection body 1 through the cleaning shaft 51; while the cleaning liquid is circulating, the turbine structure 52 and the cleaning roller 53 are rotated by the force of the liquid flow, thereby contacting and cleaning the surface of the plastic intake manifold.

[0026] like Figure 4 As shown in the figure, as a further embodiment of the present invention, the end face of the separation box 61 is fixedly connected to the detection body 1, the diameter of the hole opened on the end face of the separation filter plate 63 is smaller than the diameter of the hole opened on the end face of the filter plate structure 4, and the interior of the adsorption filter plate 62 is provided with activated carbon adsorbent; it can filter impurities in the cleaning liquid, thereby preventing impurities that fall off the plastic intake manifold during cleaning from re-entering the intake manifold, and thus achieving a good cleaning effect.
