Technical Field

[0001] The utility model relates to the technical field of cooling, in particular to an engine testing cooling circulating water device. Background Art

[0002] Cooling water circulation refers to the use of circulating cooling water to reduce the temperature of machines or equipment and prevent damage to machines or equipment caused by high temperature. The cooling water circulation system can utilize the recycling of cooling water to achieve the purpose of high efficiency and energy saving.

[0003] The engine must be tested for air tightness before assembly. The test methods are mainly divided into air test method and water test method. The water test method uses a cooling circulating water device to inject cooling water at a certain pressure into the engine cylinder to achieve the test purpose.

[0008] Furthermore, the fluid scale inhibitor is connected to the plurality of circulating water tanks via a straight-through pipe, and a return water pipeline is provided at one end of the fluid scale inhibitor.

[0009] Furthermore, the return water pipe and the second outlet water pipe are both three-way pipes, and the return water pipe and the second outlet water pipe are respectively provided with multiple return water solenoid valves 1 and 2. The return water pipe is also provided with a flow sensor 1 at the end away from the fluid scale inhibitor.

[0010] Furthermore, a water inlet pipe is provided at one end of the clean water tank, and a water inlet solenoid valve is provided on the water inlet pipe.

[0011] Furthermore, the first water outlet pipe is provided with a second water inlet solenoid valve and a second flow sensor, and the second water inlet solenoid valve is provided near the water outlet of the cooling water tank.

DETAILED DESCRIPTION

[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0019] Example

[0020] like Figure 1-2 As shown, an engine test cooling circulating water device includes a clean water tank 1, a cooling water tank 2 and multiple circulating water tanks 3. The clean water tank 1 is connected to the cooling water tank 2 through an outlet pipe 1 4, and the cooling water tank 2 is connected to the multiple circulating water tanks 3 through an outlet pipe 2 5. A fluid scale inhibitor 6 is also provided at one end of the multiple circulating water tanks 2.

[0021] The fluid scale inhibitor 6 is connected to multiple circulating water tanks 3 through a straight pipe. A return water pipe 7 is provided at one end of the fluid scale inhibitor 6. The return cooling water can be filtered and purified through the fluid scale inhibitor 6 and then enter the circulating water tank 3 to wait for re-cooling.

[0022] The return water pipe 7 and the outlet water pipe 2 5 are both tee pipes. The return water pipe 7 and the outlet water pipe 2 5 are respectively provided with multiple return water solenoid valves 1 8 and return water solenoid valves 2 9. The return water pipe 7 is also provided with a flow sensor 10 at the end away from the fluid scale inhibitor 6. Multiple uninterrupted water circulation flows are achieved through the tee pipe, which not only ensures real-time monitoring of the flow rate, but also keeps the circulating water clean.

[0023] A water inlet pipe 11 is provided at one end of the clean water tank 1, and a water inlet solenoid valve 12 is provided on the water inlet pipe 11. A water inlet solenoid valve 2 13 and a flow sensor 2 14 are respectively provided on the water outlet pipe 1 4. The water inlet solenoid valve 2 13 is arranged near the water outlet of the cooling water tank 2. Multiple solenoid valves are used for opening and closing control and flow monitoring of the inlet and outlet water flow of the clean water tank 1, the circulating water tank and the cooling water tank 2.

[0024] The capacities of the multiple circulating water tanks 3 are all smaller than those of the clean water tank 1 and the cooling water tank 2. By diverting the refluxed cooling water through the multiple circulating water tanks 3, the water capacity in the cooling water tank 2 can be effectively controlled, thereby accelerating the cooling process and improving efficiency.

[0025] During use, the cooling water in the clean water tank 1 flows into the engine water channel through the water inlet pipe 11, then flows back through the return pipe 7, is filtered by the fluid scale inhibitor 6, and is diverted to multiple circulating water tanks 3, and enters the cooling water tank 2 in batches, shortening the cooling time of the cooling water tank 2 and ensuring the recycling of the cooling water.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
