Description

Be used for observing engine business turn over water pipe degassing test frock

Technical Field

The invention belongs to the technical field of engine detection, and particularly relates to a test tool for observing degassing of a water inlet pipe and a water outlet pipe of an engine.

Background

The degassing test is an important index for testing the performance of the engine, and tests are needed to test the matching condition of the engine and the whole vehicle or the engineering machinery when the engine is matched with the whole vehicle or the engineering machinery. Out-gassing test is one of the important tests.

Good engine out-gassing has several advantages:

① after the engine is started, the air in the cooling system is removed quickly, so the corrosion of air to the water jacket and water tank of the engine can be reduced, and the service life of the engine and the water tank can be prolonged.

② the whole cooling system has no air, the heat exchange capacity of the cooling liquid can be improved, and the heat dissipation capacity of the cooling system can be improved.

③ the absence of air in the cooling system can reduce cavitation of the cylinder liner and improve the service life of the engine.

Therefore, the tool capable of observing the degassing test of the water inlet and outlet pipe of the engine is very needed.

In the prior art, most of water inlet and outlet pipes for connecting an engine are opaque rubber pipes, and the opaque rubber pipes cannot be observed normally. The anti-dropping plastic pipe is fixed between the opaque rubber pipes, but tests prove that the plastic pipe can crack when the water temperature is high, and the quartz glass pipe is added between the water inlet pipe and the water outlet pipe, but the surface of the quartz glass pipe is too smooth and is not easy to fix, so that the fixing is not firm, and time and labor are wasted.
