Embodiment Construction

[0020] see figure 1 As shown, in an embodiment of the present invention, the test device for testing the performance of a fluid control valve includes an electrical control device 1 , a basic test bench 2 and a measurement and control device 3 .

[0021] The electrical control device 1 has two power sources of 380V and 220V, which provide power for the basic test bench 2 and the measurement and control device 3, and control the power supply of the basic test bench 2 and the measurement and control device 3 through the main command switch. A voltmeter and an ammeter are respectively provided on the 220V single-phase power supply circuit and the 380V three-phase power supply circuit.

[0022] The electrical control device 1 is provided with four heating indicator lights for displaying the heating state of the test device. The four heating indicator lights are divided into two groups, which respectively indicate the working status of the heaters of the test oil tank and the hydr...

Abstract

The invention discloses a test set for detecting properties of a fluid control valve. The test set comprises an electrical control device, a basic experiment table and a measurement control device, wherein the electrical control device supplies power to the basic experiment table and the measurement control device; a low-pressure oil source and a high-pressure oil source which are positioned in the basic experiment table provide low-pressure test oil and high-pressure test oil with certain pressures, flow rates and temperatures as test sample; the measurement control device is connected with the basic experiment table, and used for acquiring test parameters of a test sample in the basic experiment table through a sensor and acquiring parameters of the basic experiment table through the sensor; and the measurement control device controls the pressures, flow rates and temperatures of the low-pressure test oil and the high-pressure test oil through the low-pressure oil source and high-pressure oil source on the basic experiment table. The test set can provide actually applied external conditions for the fluid control valve, so that the real object sample of the fluid control valve can be subjected to independent property testing without the original application system.

Description

technical field [0001] The invention relates to the field of valve element performance test and detection, in particular to a test device for detecting the performance of a fluid control valve. Background technique [0002] In order to meet the increasing performance and emission requirements of diesel engines, countries around the world continue to develop new technologies for diesel engines. Among them, the electronically controlled fuel system (including common rail system, pump nozzle system, and electronically controlled unit pump system) is an important means to improve emissions, reduce fuel consumption, and improve power performance. Fluid control valves (including high-speed solenoid valves, flow regulating valves, common rail pressure regulating valves, and injection control valves) are widely used in electronically controlled fuel injectors, high-pressure oil pumps and common rail pipes of electronically controlled fuel systems; the work of fluid control valves T...
