Description

Technical Field

[0001] The utility model belongs to the technical field of engine devices, and particularly relates to a gas engine intake system flow guiding device. Background Art

[0002] At present, supercharged and intercooled intake methods are generally adopted for high-power gas generator sets. The supercharged engine injects high-pressure and high-temperature air or combustible gas generated by a supercharger into an air cooler for cooling to reduce the temperature of the air or combustible gas. The air or combustible gas enters the combustion chamber to burn and do work, enabling the engine to operate normally. If the high-pressure and high-temperature air or combustible gas enters the air cooler unevenly or is not cooled sufficiently, it will cause the engine power to decrease, and even cause the engine to have a backfire phenomenon, seriously affecting the normal operation of the engine.

[0003] In the existing gas engine intake system, no flow guiding device is provided at the pipe before the air cooler. The high-pressure and high-temperature air flow mainly enters the air cooler through the upper part of the air cooler, resulting in uneven air intake of the air cooler and insufficient cooling, reducing the engine power and seriously affecting the normal operation of the engine. Summary of the Utility Model

[0004] According to the above deficiencies in the prior art, the utility model provides a gas engine intake system flow guiding device, which enables the high-pressure and high-temperature air flow to enter the air cooler evenly after being fully cooled, avoiding the situation that the engine power is reduced and seriously affecting the normal operation of the engine, and ensuring the long-term safe operation of the engine.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0006] The gas engine intake system flow guiding device includes a supercharger and an air cooler. An air cooler front connecting pipe is fixedly arranged at one end of the air cooler close to the supercharger. A connecting pipe is fixedly arranged at one end of the supercharger close to the air cooler. The end of the connecting pipe far from the supercharger is connected with an intake pipe, and the intake pipe is connected with the air cooler front connecting pipe. A plurality of grids are arranged inside the air cooler front connecting pipe.

[0007] Furthermore, the intake pipe is fixedly arranged at the end of the air cooler front connecting pipe far from the air cooler.

[0008] Furthermore, the air cooler front connecting pipe is integrally in a horn shape with two open ends. The large-diameter end of the air cooler front connecting pipe is connected with the air cooler, and the small-diameter end is connected with the intake pipe.

[0009] Furthermore, the grids are integrally in a trapezoidal shape. The grids include a short side and a long side arranged oppositely, and the long side of the grid is arranged on the side close to the air cooler, and the short side of the grid is arranged on the side close to the intake pipe.

[0010] Furthermore, a plurality of grids divide the air cooler front connecting pipe into a plurality of channels with the same volume.

[0011] Further, the connecting pipe is fixedly connected to the supercharger by bolts.

[0012] Further, a hose is sleeved on the outer wall of the joint of the connecting pipe and the intake pipe in a matching manner.

[0013] Further, a number of hose clamps are sleeved on the outer wall of the hose.

[0014] Further, the connecting pipe and the intake pipe are fixedly connected by the hose and the hose clamps.

[0015] Further, the hose is a cloth-reinforced silicone hose.

[0016] The beneficial effects of the present utility model are as follows:

[0022] The present utility model will be specifically described and explained below with reference to the accompanying drawings.

[0023] Embodiment 1

[0024] As Figures 1-3As shown, the gas engine intake system flow guiding device includes a supercharger 1 and an air cooler 6. At one end of the air cooler 6 close to the supercharger 1, an air cooler front connecting pipe 5 is fixedly arranged. At one end of the supercharger 1 close to the air cooler 6, a connecting pipe 2 is fixedly arranged. The end of the connecting pipe 2 far from the supercharger 1 is connected to an intake pipe 8, and the intake pipe 8 is connected to the air cooler front connecting pipe 5. A number of grids 7 are arranged inside the air cooler front connecting pipe 5. By arranging a number of grids 7 inside the air cooler front connecting pipe 5, the supercharged high-temperature and high-pressure air or combustible gas can enter the air cooler 6 more evenly, ensuring that the air or combustible gas is fully cooled, improving the cooling efficiency and service life of the air cooler 6, and ensuring the long-term safe operation of the engine.

[0025] Grid-like grids 7 are arranged inside the air cooler front connecting pipe 5 to divide the inside of the air cooler front connecting pipe 5, so that the gas in the supercharger 1 is evenly dispersed into the air cooler 6, playing a role in guiding the flow.

[0026] The intake pipe 8 is fixedly arranged at the end of the air cooler front connecting pipe 5 far from the air cooler 6.

[0027] The air cooler front connecting pipe 5 is integrally in the shape of a horn with both ends open, and the large-diameter end of the air cooler front connecting pipe 5 is connected to the air cooler 6, and the small-diameter end is connected to the intake pipe 8.

[0028] The grids 7 are integrally arranged in a trapezoidal shape. The grids 7 include a relatively arranged short side and long side, and the long side of the grids 7 is arranged on the side close to the air cooler 6, and the short side of the grids 7 is arranged on the side close to the intake pipe 8.

[0029] A number of grids 7 divide the air cooler front connecting pipe 5 into a number of channels with the same volume, enabling the supercharged high-temperature and high-pressure air or combustible gas to enter the air cooler 6 more evenly.

[0030] The connecting pipe 2 is fixedly connected to the supercharger 1 by bolts.

[0031] A hose 3 is fitted and sleeved on the outer wall at the connection of the connecting pipe 2 and the intake pipe 8.

[0033] The connecting pipe 2 and the intake pipe 8 are fixedly connected by the hose 3 and the clamps 4. The hose 3 can not only offset the vibration generated by the engine, but also facilitate the installation difficulties caused by manufacturing and installation errors of each component. The two ends of the hose 3 are fixed with the clamps 4 to ensure the sealing performance.

[0034] The hose 3 is a fabric-reinforced silicone hose. The hose 3 can be fixed according to the structures of the connecting pipe 2 and the intake pipe 8 to ensure the sealing performance at their connection.
