Abstract

The utility model discloses a fuel hose sealing performance testing device, which is characterized by comprising a hydraulic press (1) and a fuel hard tube (2), wherein one end of the fuel hard tube (2) is connected with an outlet of the hydraulic press (1), and the other end of the fuel hard tube (2) is connected with a fuel hose (4). Besides, a free end of the fuel hose (4) is provided with a plug (6), and two joint ends of the fuel hose (4) are respectively provided with a clamp (3). The fuel hose sealing performance testing device has the advantages of special design for testing the sealing performance of the fuel hose, simple structure, low manufacturing cost and capability of ensuring accuracy of test results.

Description

The fuel hose sealing property tester
Technical field
The utility model relates to automobile component test field, especially relates to a kind of test unit that is used for testing automobile fuel hose sealing property.
Background technology
The fuel oil supply system of automobile be fuel tank of vehicle to the oil feed line system between the engine, and fuel hose partly is the weakest and most important parts in the oil supply system.The sealing of fuel hose, especially the sealing property at interface is the important indicator of decision fuel hose stability, in case the sealing property of fuel hose reduces, then can cause very big influence to the fuel feeding of automobile.Owing to there is not special fuel hose proving installation, usually the performance of fuel hose being carried out testing experiment is to adopt integrated fuel oil supply system testing table, and the function of this testing table is many, and reliability is higher, but the complex structure of this testing table involves great expense accordingly.The Chinese utility model patent instructions of the CN201000395Y that on January 2nd, 2008 was announced discloses a kind of vehicle fuel oil supply system life test rack, this testing table comprises high low temperature insulation explosion-proof tank, test fuel delivery and flow, pressure regulating system and computer measurement machine explosion-proof electrification system, the functional integration height of this testing table, reliability is also higher, but complex structure, cost is too high, in the automobile production of pipeline system, the test event difference of each link, so do not need to use expensive fuel oil supply system testing table, design then unusual necessity of a kind of sealing property tester for fuel hose separately.
The utility model content
The utility model mainly is to solve the integrated fuel oil supply system test platform structure complexity that exists in the prior art, involve great expense, and only fuel hose is carried out the problem that experiments of sealing performance does not need to use complicated test unit, a kind of fuel hose sealing property tester is provided, this device is the sealing property design separately for the test fuel hose, both guaranteed the reliability of testing experiment, again can the short form test apparatus structure, reduce experimentation cost.
In order to solve the problems of the technologies described above, the utility model has adopted a kind of like this fuel hose sealing property tester, this device comprises hydropress and fuel oil hard tube, described fuel oil hard tube one end is connected with the outlet of hydropress, the other end connects fuel hose, free end at described fuel hose is provided with obstruction, at two tip sides of described fuel hose clip is set respectively.During test, fuel hose is installed on request the primer fluid press, the output pressure of hydropress is set to the working pressure of fuel pump, do continuation and intermittent pressure test, observe the fuel hose two ends and whether occur leaking, thereby can judge whether fuel hose is qualified.The utility model aims at the sealing property of test fuel hose and designs, and simple in structure, cost of manufacture is low, accuracy that can the warranty test result.
As preferably, the clamping force of described clip is 2N ~ 3N.
As preferably, the obstruction of described obstruction for making with the fuel oil hard tube, described obstruction one end opening, the other end seals.Stop up and adopt fuel hose to make, the operating mode in the time of can further simulating fuel hose work makes the result of test more accurate.
The beneficial effects of the utility model are to aim at the sealing property of test fuel hose and design, and simple in structure, cost of manufacture is low, accuracy that can the warranty test result.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
As shown in Figure 1, the fuel hose sealing property tester of present embodiment, comprise hydropress 1 and fuel oil hard tube 2, fuel oil hard tube 2 one ends be connected with the outlet of hydropress 1 that the other end connects fuel hose 4, the free end of fuel hose 4 is sealed with stopping up 6, stop up 6 and use the fuel oil hard tube to be prepared from, an end opening, end sealing, two tip sides at described fuel hose 4 are provided with clip 3 respectively, and the clamping force of clip 3 is 3N.
During test, fuel hose is installed on request the primer fluid press, the output pressure of hydropress is set to the working pressure of fuel pump, do continuation and intermittent pressure test, observe the fuel hose two ends and whether occur leaking, thereby can judge whether fuel hose is qualified.The utility model aims at the sealing property of test fuel hose and designs, and simple in structure, cost of manufacture is low, accuracy that can the warranty test result.
