Solenoid valve driver and hydraulic support control system

Abstract

The embodiment of the invention discloses an electromagnetic valve driver and a hydraulic support control system. The electromagnetic valve driver comprises an energy storage part, the energy storagepart comprises an energy storage unit for storing electric energy, and the energy storage unit is used for providing the electric energy for switch-on and switch-off of an electromagnetic valve. The electric energy is provided for switch-on and switch-off of the electromagnetic valve through the energy storage part, and an intrinsic safety power source is not needed for supplying the electric energy to the electromagnetic valve. Compared with the prior art that the intrinsic safety power source is directly used for supplying power to the electromagnetic valve, the peak power consumption in anintrinsic safety power source circuit can be reduced, the number of loads of the intrinsic safety power source is increased, the output power fluctuation of the intrinsic safety power source is reduced, the output power of the intrinsic safety power source is prevented from being suddenly increased, the safety coefficient of the intrinsic safety power source can be improved, the service life of the intrinsic safety power source can be prolonged, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of solenoid valves, in particular to a solenoid valve driver and a hydraulic support control system. Background technique [0002] The fully mechanized mining work faces higher and higher performance requirements of electronic control equipment and more and more functional requirements, and the power supply end has been unable to provide safe high-power power supply due to industry safety regulations. The requirements are getting more and more demanding. [0003] On the fully mechanized mining face in the prior art, multiple hydraulic supports use a set of intrinsically safe power supplies, and each hydraulic support is equipped with multiple electromagnetic pilot valves. When multiple hydraulic supports act simultaneously, the total power supply current of the intrinsically safe power supply is The power consumption and power consumption will suddenly increase, which not only poses a safety hazard, but als...

Problems solved by technology

[0003] On the fully mechanized mining face in the prior art, multiple hydraulic supports use a group of intrinsically safe power supplies, and each hydraulic support is equipped with multiple electromagnetic pilot valves. When multiple hydraulic supports operate at the same time, the total power supply current of the intrinsically safe power supply and power consumption will suddenly increase, which not only has potential safety hazards, but also shortens the life of the intrinsically safe power supply, limiting the number of intrinsically safe power supplies with loads
