Thermal-spraying fuel spraying control system and control method capable of implementing fully closed-loop automatic control

Abstract

The invention provides a thermal-spraying fuel spraying control system and control method capable of implementing fully closed-loop automatic control. The thermal-spraying fuel spraying control systemcomprises a control cabinet, a fully closed-loop automatic control board structure, a ventilation dust removal fan structure, a damping movement seat structure, a protective cover, a dust guide pipe,a dust storage box, a supporting seat, a nameplate, a cabinet door, a connecting rod lock, a supporting base, a feeding pipe, a mass flow controller, a storage rack, a material guide pipe, a flow sensor and a discharge pipe; and the control cabinet body is connected to the upper surface of the supporting base by a bolt. According to the invention, arrangement of a touch screen display is beneficial for carrying out convenient control on thermal-spraying fuel equipment, and the touch screen display is simple and convenient to operate; arrangement of a control button, a PLC, the mass flow controller and the flow sensor is beneficial for implementing fully closed-loop automatic control and improving the intelligent degree of operating and controlling the equipment; and arrangement of a ventilation fan and fan blades is beneficial for carrying out ventilation, heat dissipation and dust removal on the inside of the control cabinet so as to ensure operation safety of the equipment inside.

Description

technical field [0001] The invention belongs to the technical field of thermal spraying fuel control cabinets, and in particular relates to a thermal spraying fuel spraying control system and a control method of full-closed-loop automatic control. Background technique [0002] The common thermal spraying fuel spraying control mechanism is to control the flow rate of the combustion aid and fuel during spraying by adjusting the pressure or the manual valve of the glass rotameter. With the fluctuation of the pressure of the supplied combustion aid and fuel, the corresponding actual flow rate will also fluctuate. When the supply pressure decreases, the flow rate of the supplied combustion oxidant and fuel will also decrease; when the supply pressure increases, the flow rate of the supplied combustion oxidant and fuel will also increase. If you want to stabilize the flow, you need to manually adjust the manual valve to continuously control the flow in real time. [0003] The Ch...
