Hydraulic substation and electromagnetic valve control device

Abstract

The invention provides a hydraulic substation and electromagnetic valve control device. The hydraulic substation and electromagnetic valve control device comprises a coordination loading control system, a power supply, three relays, a plurality of air switches, a plurality of switching plugs, a cable, an electromagnetic valve and a hydraulic substation switching panel, wherein the coordination loading control system and the power supply are connected with the relays, the relays are connected with the switching plugs through the air switches, the switching plugs are connected with the electromagnetic valve and the hydraulic substation switching panel, and the control of the electromagnetic valve and the hydraulic substation is realized through the logic combination design of the components.According to the device, the electromagnetic valve and the hydraulic control can be synchronous, so that the high-efficiency management of the personnel on the field equipment is facilitated, the fault elimination is simplified, the signal loss is reduced, and meanwhile, the test safety and reliability are also improved.

Description

technical field [0001] The invention relates to a control device between electrical equipment, in particular to a control device for hydraulic substations and electromagnetic valves used in aircraft strength tests. Background technique [0002] In the aircraft structural strength test, it is necessary to control the solenoid valve in the hydraulic sub-station and the hydraulic cylinder. The current industry-wide solution is to separate the control of the solenoid valve and the hydraulic sub-station. The control boxes of the power supply and hydraulic sub-station are generally placed in the In the control room or activity room, the transfer box of the solenoid valve is placed on the test site, mixed with the test pieces and field test equipment. [0003] However, when the solenoid valve control in the hydraulic substation and hydraulic cylinder fails, the general solution will make it difficult to check the fault, the output signal of the solenoid valve control has a large pr...

AI Technical Summary

Problems solved by technology

[0003] However, when the solenoid valve control in the hydraulic substation and hydraulic cylinder fails, the general solution will make it difficult to check the fault, the output signal of the solenoid valve control has a large pressure drop, and there are certain safety hazards. After the cables between the cables fail, the maintenance is more cumbersome, and the fault is difficult to eliminate
