Description

Fuel Injection Valve Multi-test Equipment for Marine Diesel Engine

The present invention relates to a test apparatus, and more particularly, it is possible to conveniently and reliably verify the suitability by measuring the opening pressure of the fuel injection valve for engines used in ships in an automatic operation method, and at the same time inspect a plurality of The present invention relates to a fuel injection valve multi test apparatus for a ship engine, which can also reduce inspection time.

In general, the fuel injection valve of a marine diesel engine determines the efficiency and life of the engine according to the opening pressure (injection pressure). In other words, if the open pressure does not satisfy the reference pressure, unstable combustion causes air pollution and fuel consumption increases.

Therefore, the opening pressure of fuel injection valve of ship diesel engine should be maintained properly. To this end, fuel injection valve test equipment for ship diesel engines has been developed to verify the suitability by measuring the open pressure of the fuel injection valve manufactured after manufacturing.

The fuel injection valve test equipment of the conventional marine diesel engine has a structure for measuring and testing the opening pressure of the fuel injection valve and the injection type injected through the fuel injection hole by supplying test oil to the fuel injection valve. 1785407 'fuel injection valve test equipment for ship diesel engine' (hereinafter referred to as 'prior art 1') and Korea Patent Publication No. 10-2015-0049873 'fuel injection valve test equipment for ship diesel engine' (hereinafter 'Prior Technology' 2 '), and these conventional products (model name VTU-1100N)) are manufactured and sold as shown in FIG.

On the other hand, the conventional test equipment shown in Figure 1 has the advantage in that the fuel injection valve test process can be made automatically simply and concise without complicated operation, there is a problem that the following inconvenience exists.

Specifically, conventional test equipment can only test one fuel injection valve at a time. That is, in the case of the test equipment illustrated in FIG. 1, only one fuel injection valve may be tested at a time because only one oil collecting unit 3 capable of installing and testing the fuel injection valve is configured. Therefore, in the case of a processing company that manufactures and supplies fuel injection valves, the delivery is performed after checking the suitability of the manufactured fuel injection valves. In order to increase the inspection efficiency for determining the suitability of the manufactured fuel injection valves, a plurality of tests are performed. There was a problem that equipment must be provided and accordingly cost and inspection personnel are also required.

In addition, in the case of the conventional test equipment, there are too many inconveniences and inconveniences in installing and dismantling the fuel injection valve during the test of the fuel injection valve. Specifically, referring to FIG. 2, FIG. 2 sequentially shows a process of installing a fuel injection valve in an oil collecting unit including an oil collecting container and a cap installed at an upper portion thereof to inspect the fuel injection valve through a conventional test equipment. In the installation of the fuel injection valve, the operator first places the fuel injection valve in the valve mounting hole formed in the cap of the oil collecting unit from which the coupling clamp is removed as shown in (a). At this time, the fuel injection valve positioned in the valve mounting hole is in a state in which the fuel injection valve is inclined as shown in (b) when the operator mounts the fuel injection valve while the tip is supported in the valve mounting hole.

Then, as shown in (c), the operator couples the coupling clamps to both sides of the pair of fixed bars erected in the oil collecting unit, and then engages the coupling clamps by holding the inclined fuel injection valve by hand.

Next, to secure the fuel injection valve in the state where the fuel injection valve and the connection clamp are coupled as shown in (d), both sides of the connection clamp are firmly fixed to the fixing bar by using a nut.

Then, after connecting the test oil supply hose to the upper side of the connecting clamp as shown in (e), the test oil is supplied to test the fuel injection valve, the fuel injection valve is completed in the reverse order of the above Are separated.

As described above, in the test using the conventional test equipment, the process of installing and removing the fuel injection valve is complicated, and most of the installation process requires the intervention of the operator, in particular, the coupling of the nut for fixing the connecting clamp in step (d). The installation process for a single fuel injection valve test took longer than the time required for the test, such as requiring additional equipment such as an electric drill.

In addition, another problem is that it is not easy to check the injection form of the fuel injection valve through the oil collecting unit. When the test oil is supplied to the fuel injection valve specifically installed, the test oil is sprayed through the injection hole of the fuel injection valve and the spray condition is visually checked to test whether the spray type is appropriate or the injection hole of the fuel injection valve. Check the condition of oil like water droplets. However, when the test oil is sprayed on the inner wall of the oil collecting unit, and the oil collecting unit is opaquely deteriorated by the repeated test, and thus deteriorated so that the spray type cannot be determined as shown in FIG. If the inner wall of the oil collecting unit is difficult to wipe off or even difficult, there is an inconvenience of having to replace the new oil collecting unit.

Finally, there is a problem that there is no application of a separate pressure regulating structure in the case of the existing oil collector. Specifically, since the oil collecting part has a cylindrical structure and the test oil is sprayed with a strong pressure inside, when the valve is completely sealed, when the valve is removed, the valve may spring up due to the elevated pressure inside the oil collecting part. There is a problem that may occur if the worker is injured. At this time, the holes formed in the cap of Figure 2 is a coupling hole for moving the position of the fixed bar, the applicant is a hole formed through the arbitrary processing, the small hole in the tip is a preformed hole that is connected to the drain pipe connected to the connection clamp (See Fig. 1). Therefore, the oil collecting part in the product state is a closed structure.

On the other hand, if the oil collector is not completely sealed, the sprayed test oil is leaked out of the oil collector and comes into contact with the worker, thereby adversely affecting the health of the worker. Therefore, since there is no separate internal pressure control structure in the oil collecting unit, it causes various problems in the worker's working environment.
