Problems solved by technology
[0004] Traditional testing of solenoid valves often requires multiple independent tests to test whether the performance of the solenoid valve meets the requirements. The test cycle is long and the level of intelligence is low, which is not conducive to shortening the development cycle of the solenoid valve and improving the reliability of the test.

Embodiment Construction
[0019] Such as Figure 1-Figure 4 As shown, the present invention consists of a solenoid valve performance test bench and a measurement and control device. The solenoid valve performance test bench mainly includes a hydraulic circuit and a control chamber 11 . The hydraulic circuit is connected to the test solenoid valve 10 through the oil circuit, and the test solenoid valve 10 is connected to the interface of the control chamber 11 through the oil circuit, and the hydraulic circuit provides the test working pressure environment for the test solenoid valve 10 . The control chamber 11 is a hydraulic chamber with adjustable volume, which is used as the control object of the solenoid valve instead of the fuel injector. The control cavity screw rod 30 is made up of three sections, the upper section is the rotary handle 28, the middle section is the screw thread, and the lower section is the optical axis. The optical axis on the screw rod 30 is matched with the cavity 29 . Ther...

An electromagnetic valve test platform comprises an electromagnetic valve performance test test-bed and a measuring and control device. The electromagnetic valve performance test test-bed mainly comprises a hydraulic circuit and a control cavity. The hydraulic circuit is connected with the electromagnetic valve to be tested by virtue of an oil path, and the electromagnetic valve to be tested is connected with an interface of the control cavity by virtue of the oil path. The measuring and control device comprises a LabVIEW test platform, a data collection card, a plurality of sensors and a microcomputer. The microcomputer is connected with the data collection card by virtue of a wiring harness, and then the data collection card is connected with each sensor by virtue of a circuit. The electromagnetic valve test platform has the characteristics of high integration level, strong reliability, high intellectualization level and the like, and can be used for performing electromagnetic valve flow property and response property test, anti-vibration and anti-oil pollution capacity test and reliability test, and the development period of the electromagnetic valve is shortened.
Description
technical field [0001] The invention relates to a solenoid valve test platform, in particular to a solenoid valve test platform for a diesel engine high-pressure common rail electronically controlled fuel injection system. Background technique [0002] High-speed solenoid valves can realize independent control of fuel supply and fuel injection, as well as flexible control of fuel injection timing and fuel injection volume, and are widely used in high-pressure common rail fuel injection systems of diesel engines to improve the power and economy of diesel engines. The performance requirements of the high-pressure common rail fuel injection system for the solenoid valve are high speed, large flow, strong electromagnetic force, good heat dissipation effect, and compact structure. [0003] In the development process of solenoid valves, computer simulation is mostly used in the preliminary design. Due to the limitations of the modeling method itself, the reliability of the design ...
