Abstract

The invention discloses a combined multifunctional servo-valve testing tool, which comprises a fixing block 1, a cover plate 2 and a front-stage test adapter 5. The fixing block 1 is a block structure with oil paths arranged therein, and two oil source holes 6 matching with a mechanical servo-valve interface, two control cavity holes 7 and a plurality of mounting holes are arranged in the upper surfaces of the fixing block 1, the two oil source holes 6 respectively communicate with two oil source connecting holes 4 in the fixing block 1. The fixing block 1 is also provided with two flow test holes 8 and two pressure test holes 3, and the flow test holes 8 match with a flow meter mounting interface. Oil paths passing the internal of the fixing block 1 respectively communicate with pressure test hole 3 in the side surface of the fixing block 1. The cover plate 2 is detachably fixed on the flow test holes 8 in the fixing block 1 to block the flow test holes 8 during installation. The two control cavity holes 7 respectively communicate with the pressure test hole 3 in the fixing block 1. The combined multifunctional servo-valve testing tool effectively improves the testing accuracy and the debugging efficiency of an electro-hydraulic servo valve.

Description

technical field [0001] The invention belongs to electro-hydraulic servo valve technology, in particular to a combined multifunctional servo valve testing tool. Background technique [0002] The electro-hydraulic servo valve is an electro-hydraulic conversion component. The electro-hydraulic servo valve is a precision product, and the product debugging is complicated, involving many debugging procedures and testing items. In the debugging process of the electro-hydraulic servo valve, it is necessary to carry out frequent parameter debugging and testing on the component level of the servo valve and the servo valve as a whole, until the performance of the servo valve can meet the index requirements. During the debugging process of the electro-hydraulic servo valve, the servo valve component level and the overall debugging of the servo valve need to be carried out on a test bench with corresponding test conditions. The test process is cumbersome and highly dependent on the test...
