[0003] As a cooling method of the engine, water cooling is increasingly applied to motorcycle engines. A reliable water cooling system can not only improve the power and comfort of the engine, but also prolong the service life of the engine. Therefore, how to evaluate a water cooling system Whether it is safe and reliable, in addition to the performance and life of each component, the most critical thing is how to test the airtightness of the entire water cooling system. If the airtightness of the water cooling system is not up to standard, it will cause the engine temperature to be too high and affect the performance of the engine. service life, but currently there is no set of detection equipment to detect the airtightness of motorcycle engine water cooling system

Embodiment Construction
[0036] The preferred embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0037] Such as figure 1 As shown, the airtightness detection device of the motorcycle engine water-cooling system of the present invention includes a storage box 1, and the storage box 1 is used to store the medium for applying pressure. In this embodiment, the medium used is cooling liquid or compressed air . The top of the storage box 1 is provided with an atmospheric balance port 101 and a medium input port 103, and the bottom of the storage box 1 is provided with an overflow port 102 and a medium output port 104, and the overflow port 102 is blocked with a bolt 9 during detection;
[0038] Rubber tube 2, the rubber tube 2 is provided with multiple pieces, which are connected with the joints of each component in turn, and are tightly held at the joints with clamps to ensure that the joints will not leak during the pressurizati...

Disclosed is a leakproofness detection device for a motorcycle engine water-cooling system. The device includes a storage tank, a pneumatic pump, a first throttle valve, an overflow valve, a pressure meter and a second throttle valve. A rubber pipe is sequentially connected with joints of the above-mentioned parts. A rubber pipe is also connected between a water outlet of a heat radiator and a water inlet of an engine. A heat radiator valve cover is also installed on the heat radiator. A medium passes the storage tank, a filter, the pneumatic pump, the first throttle valve, the heat radiator, the engine, the second throttle valve and the storage tank so that a circulation loop is formed. When the device is adopted for detection, pressure adjustment and pressure maintaining functions can be realized in the circulation loop so that after the water-cooling system is sealed under a constant pressure for a specific time, whether the leakproofness of the water-cooling system is up to standard is judged through utilization of whether pointer change of the pressure meter is within a range allowed by a tolerance. The leakproofness detection device has the characteristics of being simple in structure and convenient to operate and is capable of simulating different pressures to detect the leakproofness of the water-cooling system.
Description
technical field [0001] The invention relates to a detection device and method, in particular to a detection device and detection method for the airtightness of a motorcycle engine water cooling system. Background technique [0002] The function of the motorcycle engine cooling system is to dissipate part of the heat absorbed by the heated parts in time to ensure that the engine works at the most suitable temperature. The cooling system of the engine is usually divided into air-cooled and water-cooled. The cooling system with air as the cooling medium is called the air-cooled system; the cooling system with the coolant as the cooling medium is called the water-cooled system. [0003] As a cooling method of the engine, water cooling is increasingly applied to motorcycle engines. A reliable water cooling system can not only improve the power and comfort of the engine, but also prolong the service life of the engine. Therefore, how to evaluate a water cooling system Whether it ...
