Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Because the airflow generated in the combustion process of the engine is pulsed, the measured intake and exhaust pressure is not very stable, and in order to more accurately measure the intake and exhaust pressure of the engine and obtain more accurate and credible data, the development of a pressure stabilizing device for measuring the intake and exhaust pressure of the engine is urgently needed.
In view of the above, the present invention provides a pressure stabilizing device for measuring intake and exhaust pressures of an engine, which can convert a pulse type airflow at an intake and exhaust port of a tested engine into a pressure-stable airflow to be provided to a pressure test setting, so as to ensure accuracy and stability of the pressure test setting on the intake and exhaust pressure test of the engine.
As shown in fig. 1 and 2, the pressure stabilizing device for measuring the intake and exhaust pressures of the engine provided by the utility model comprises a pressure stabilizing and flow stabilizing barrel 1, an intake pipe 2, an outlet pipe 3 and an emptying pipe 4, wherein:
the top of the pressure and flow stabilizing barrel 1 is provided with an air inlet, the side wall of the pressure and flow stabilizing barrel 1 is provided with an air outlet, and the bottom of the pressure and flow stabilizing barrel 1 is provided with an emptying hole.
One end of the air inlet pipe 2 is hermetically connected to an air inlet hole, and the other end of the air inlet pipe 2 is used for connecting an air inlet and outlet of an engine to be tested. One end of the air outlet pipe 3 is hermetically connected to the air outlet hole, and the other end of the air outlet pipe 3 is connected to an air inlet collecting port arranged for pressure testing.
One end of the emptying pipe 4 is connected to the emptying hole in a sealing mode, and the other end of the emptying pipe 4 is connected with a removable plug 5.
The working process of the pressure stabilizing device for measuring the air inlet and exhaust pressure of the engine is as follows:
before measurement, the air inlet pipe 2 is connected to an air inlet and outlet of an engine to be tested, the air outlet pipe 3 is connected to an air inlet collecting port arranged in a pressure test, and the end opening of the emptying pipe 4 is plugged by a plug 5.
The air current of the air inlet and outlet of the engine flows into the pressure stabilizing and flow stabilizing barrel 1 through the air inlet pipe 2, and the air current stabilized by the pressure stabilizing and flow stabilizing barrel 1 finally flows into the air inlet collection port arranged in the pressure test through the air outlet pipe 3 to be collected.
The temperature of the air current from the air inlet and outlet of the engine is high, and the air current contains a large amount of moisture, the high-temperature air current is cooled after entering the pressure stabilizing and flow stabilizing barrel 1, and the moisture in the high-temperature air current is condensed to form condensed water to stay in the pressure stabilizing and flow stabilizing barrel 1, so that the condensed water cannot enter the pressure test setting, and the corrosion of the air current to the pressure test setting is reduced.
When the condensed water in the pressure-stabilizing and flow-stabilizing barrel 1 is excessive, the plug 5 is removed from the tail end of the emptying pipe 4, and the condensed water can be emptied.
With continued reference to fig. 1 and 2, optionally, a first cutting ferrule 21 is welded at the air inlet, and one end of the air inlet pipe 2 is connected to the first cutting ferrule 21 through a first nut 22. A second clamping sleeve 31 is welded at the air outlet, and one end of the air outlet pipe 3 is connected to the second clamping sleeve 31 through a second nut 32. A third clamping sleeve 41 is welded at the emptying hole, and one end of the emptying pipe 4 is connected to the third clamping sleeve 41 through a third nut 42.
Optionally, the air inlet pipe 2, the air outlet pipe 3 and the emptying pipe 4 are made of high-temperature-resistant, corrosion-resistant and air-tight tetrafluoride pipes.
Optionally, a pressure measuring hole is formed in the side wall of the pressure and flow stabilizing barrel 1, and a pressure measuring joint is connected to the pressure measuring hole. The pressure measuring joint can be connected with a pressure sensor to monitor the air pressure in the pressure stabilizing and flow stabilizing barrel 1.
