Abstract
Description
Technical Field
[0001] This utility model relates to a tool for detecting intake pressure relief of turbochargers in mining vehicle engines, belonging to the field of non-ferrous metal mining technology. Background Technology
[0002] Mining vehicles are mainly used for transporting materials such as ore and slag in mines. Due to the harsh working environment, complex and undulating road conditions, the engines of mining vehicles often experience a decrease in power after long-term use, and the throttle cannot reach the maximum speed. The fault often occurs in the intake system of the engine turbocharger, which leaks and requires frequent maintenance. Since the engine is accompanied by a noisy roar and vibration during operation, it is difficult to accurately determine the location of the leak by relying solely on human hearing and touch. In addition, the noisy and harsh working environment results in low work quality and efficiency. Utility Model Content
[0003] The purpose of this invention is to provide a vehicle engine turbocharger intake pressure relief testing tool to solve the aforementioned problems. This tool utilizes a modified air gun to create a self-made engine intake pressure relief testing device. Firstly, it improves the working environment for testing engine turbocharger intake pressure relief, allowing the test to be performed with the engine off, eliminating the noise and vibration associated with engine operation. The tool is installed by removing the truck engine turbocharger intake port and connecting the air gun to an external air pump via the intake end. Simultaneously, pressing the air gun control switch allows the high-pressure airflow provided by the air pump to flow through the quick-connect fitting (intake end) into the air gun body, and then through the quick-connect fitting (outtake end) and air hose to the engine. The air intake system of the turbocharger is inspected, and then the air gun control switch is disconnected. By observing the change in the pressure gauge value on the air gun, it is determined whether there is a pressure leak in the engine turbocharger pipeline. Without the influence of engine noise and vibration, the leak can be clearly heard or accurately located by touch, thus facilitating later maintenance. Using the engine turbocharger intake pressure leak detection tool provided by this utility model can greatly improve the inspection working environment, find the location of engine turbocharger pipeline pressure leaks in a shorter time, and greatly improve the quality and efficiency of inspection and maintenance work. Moreover, this detection device is applicable to the detection of engine turbocharger pipeline pressure leaks of various vehicle models in mining, and has high practicality.
[0004] To achieve the above objectives, the present invention provides the following technical solution:
[0005] The engine turbocharger intake pressure relief testing tool provided by this utility model includes a pressure testing chamber and a modified air gun. The pressure testing chamber and the modified air gun are connected by an air passage hose. The pressure testing chamber is a cylindrical hollow structure and consists of an air passage hose, a straight quick connector, a clamp, and a rubber hose body. Furthermore, a pressure gauge is installed on the top of the modified air gun.
[0006] The pressure testing chamber consists of an air hose, a quick-connect coupling, a clamp, and a rubber hose body. The air hose is a cylindrical hollow structure, with one end connected to the clamp via the quick-connect coupling. The clamp is an annular cap-shaped structure. The rubber hose body is a cylindrical hollow rubber structure, and it is available in various diameters to suit the testing of turbochargers for various vehicles and models. The modified air gun is a modified air gun with a pressure gauge added. One end of the air hose is connected to the air inlet of the turbocharger, and the other end is connected to the quick-connect coupling (air outlet) of the air gun to complete the detection of intake pressure relief of the turbocharger.
[0007] Using the aforementioned engine turbocharger intake pressure relief detection tool, the engine should first be turned off. Remove the turbocharger intake port and install the hose body to the intake port. Connect the hose body and the modified air gun via a flexible air hose. Connect an external air pump to the air gun via the quick-connect fitting (intake end). Simultaneously press the air gun control switch to allow the high-pressure airflow provided by the air pump to rush into the air gun body through the quick-connect fitting (intake end). Then, allow the external high-pressure air to rush into the engine turbocharger's intake system via the flexible air hose. Finally, disconnect the air gun switch. The change in pressure gauge readings on the air gun will indicate whether there is pressure relief in the lines. The leak can be clearly heard or felt by hand, thus locating the fault.
[0008] As a preferred option, the aforementioned mining vehicle engine turbocharger intake pressure relief detection tool improves the working environment for detecting engine turbocharger intake pressure relief. It can perform turbocharger pipeline pressure relief detection when the engine is off, eliminating the impact of noise and vibration generated during engine operation on turbocharger pipeline pressure relief detection. The leak point in the engine turbocharger pipeline can be clearly heard or accurately found by touch, thereby detecting the location of the fault.
[0009] Preferably, the pressure testing chamber consists of an air hose, a quick-connect coupling, a clamp, and a rubber hose body. The air hose is made of soft PU material, and the rubber hose body is made of hollow rubber. The air hose and the rubber hose body are connected by a quick-connect coupling and a clamp. The rubber hose body of the pressure testing chamber is available in various sizes to suit the testing of various vehicles and engine turbochargers of various models.
[0010] Preferably, the modified air gun is connected to an external air pump via a quick-connect fitting (air inlet) and to the pressure gauge chamber via a quick-connect fitting (air outlet), thereby forming a high-pressure sealed space between the vehicle engine turbocharger, the pressure gauge chamber, and the modified air gun.
[0011] Preferably, the modified air gun is equipped with a pressure gauge, which is connected to the air gun body via a quick connector. By observing the changes in the pressure gauge reading on the air gun, it is possible to determine whether there is a leak in the engine turbocharger pipeline. Without the influence of engine noise and vibration, the leak can be clearly heard or accurately located by touch, thus detecting the fault location.
[0012] The beneficial effects are as follows: This utility model uses a pressure testing chamber composed of a cylindrical rubber tube connected by an air hose and an annular clamp. The modified air gun quick-connect connector (air outlet end) is connected to the pressure testing chamber, thus creating a self-made engine intake pressure relief detection tool. Firstly, it improves the working environment for detecting engine turbocharger intake pressure relief. In the past, the traditional detection method required the engine to be running, accompanied by the engine's noisy roar and vibration, relying solely on human hearing and touch to identify whether there was any leakage in the engine turbocharger. Moreover, it was difficult to accurately determine the location of the leakage.
[0013] Now, by using a self-made engine intake pressure relief detection tool, the engine can be shut off, eliminating the noise and vibration of engine operation. The truck engine turbocharger intake port can be removed, the tool installed, and the air gun connected to an air pump allows high-pressure air to enter the intake system. After disconnecting the air gun, the pressure gauge reading is observed to determine if there is pressure relief in the turbocharger lines. Without the noise of engine operation, the leak can be clearly heard or felt, making it easy to pinpoint the location of the leak. This significantly improves the working environment, allows for faster turbocharger intake pressure relief detection, and greatly enhances work quality and efficiency. Attached Figure Description

[0023] See Figures 1-4As shown, this utility model provides a tool for testing the intake air pressure relief of a turbocharger in a mining vehicle engine, comprising a pressure testing chamber and a modified air gun.

The air gun is connected by an air hose 101, a quick-connect fitting 102, and an air gun quick-connect fitting (outlet end) 201. During use, the engine is first turned off. The engine turbocharger inlet is removed, and the hose body 104 is installed at the turbocharger inlet. The hose body 104 is then connected to the modified air gun's quick-connect fitting (outlet end) 201 via the air hose 101. An external air pump is then connected via the air gun's quick-connect fitting (inlet end) 202. The air gun control switch 206 is pulled, and the high-pressure air is supplied through the quick-connect fitting (inlet end) 202 via the external air pump.

Then, the air gun control switch 206 is disconnected, creating a sealed space around the engine turbocharger, the pressure gauge chamber, and the modified air gun. By observing the pressure gauge 203 on the air gun, it is easy to determine if there is any pressure leakage in the engine turbocharger's pipeline. Furthermore, the engine is off during the testing process, improving the working environment for detecting intake pressure leakage in the engine turbocharger and eliminating the need to ignite the engine.
