Description

Technical Field

[0001] The utility model relates to the technical field of cylinder heads, in particular to a flow resistance measuring device for a cylinder head. Background Technique

[0002] The function of the cylinder head is to seal the cylinder, jointly form a combustion space with the piston, and bear the action of high-temperature and high-pressure combustion gas. The cylinder head bears the gas force and the mechanical load caused by tightening the cylinder bolts. At the same time, it also bears a very high thermal load due to contact with high-temperature combustion gas. In order to ensure the good sealing of the cylinder, the cylinder head should neither be damaged nor deformed. Therefore, the cylinder head should have sufficient strength and stiffness.

[0003] The cylinder head is fastened to the top of the engine block with bolts and becomes the top component of the diesel engine, so it is commonly called the cylinder head. When the existing device measures the flow resistance of the cylinder head, multiple pipes are required for connection. When measuring it, due to the large impact force of the water flow, it will cause slight shaking of the cylinder head body, and this shaking will affect the accuracy of the flow resistance measurement of the cylinder head body. Therefore, we propose a flow resistance measuring device for a cylinder head to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a flow resistance measuring device for a cylinder head to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

Above the fixing plate is placed a cylinder head body. The front surface and the back surface of the cylinder head body are both clamped with clamping plates.

[0007] In a further embodiment, a connecting plate is fixedly connected inside the water storage tank. The upper surface of the connecting plate is fixedly connected with an electric water pump. The input end of the electric water pump penetrates through the connecting plate and extends to the inside of the connecting plate. The upper surfaces of the water storage tank and the placement box are jointly fixedly connected with a limiting plate.

[0022] Please refer to Figures 1-4, in the present utility model, a cylinder head flow resistance measuring device includes a support plate 1.

Above the fixed plate 13, a cylinder head body 16 is placed. On the front and back surfaces of the cylinder head body 16, clamping plates 20 are clamped. On one side surface away from each other of each clamping plate 20, a limiting rod 14 is fixedly connected. On the front and back surfaces of the fixed plate 13, clamping grooves 22 are opened. One end of each limiting rod 14 close to each other is clamped with the clamping groove 22. Inside each clamping groove 22, a clamping block 21 is provided. The bottom end of each clamping block 21 penetrates through the limiting rod 14 and the fixed plate 13 and extends to the outside of the fixed plate 13. Each clamping block 21 is clamped with the limiting rod 14.

[0023] Inside the water storage tank 2, a connecting plate 3 is fixedly connected. On the upper surface of the connecting plate 3, an electric water pump 4 is fixedly connected. The input end of the electric water pump 4 penetrates through the connecting plate 3 and extends to the inside of the connecting plate 3. On the upper surfaces of the water storage tank 2 and the placement box 11, a limiting plate 15 is fixedly connected together. On the upper surface of the limiting plate 15, a multi-way pipe 6 is fixedly connected. The multi-way pipe 6 is fixedly communicated with the output end of the electric water pump 4. On the right side surface of the multi-way pipe 6, a plurality of connecting pipes 7 are fixedly communicated. The bottom ends of the plurality of connecting pipes 7 are jointly communicated with the cylinder head body 16.

In order to ensure the stability of the cylinder head body 16, finally, the clamping block 21 penetrates through the card slot 22 and is clamped with the limiting rod 14 to strengthen the fixation of the cylinder head body 16. Subsequently, a plurality of connecting pipes 7 are connected and installed with the cylinder head body 16, and the electric water pump 4 is started to pour the liquid in the water storage tank 2 into the cylinder head body 16 through the electric water pump 4 and keep it flowing. Finally, the flow resistance data is measured by the flow sensor 19 and the pressure sensor 9.
