Abstract

The invention relates to an axial-flow-fan training model. For filling the void of the prior art and solving the technical problems, the axial-flow-fan training model comprises an axial-flow-fan control circuit, and the axial-flow-fan control circuit comprises a hydraulic-pump-station manual control analog circuit, a fan manual control analog circuit and an air-door manual control analog circuit.The axial-flow-fan training model is characterized by also comprising an air shaft model, an air flue box, a diffusion cylinder and a diffusion cylinder model, all the parts are sequentially communicated, an air door is arranged at the end, close to the air shaft model, of the air flue box, and the fan manual control analog circuit comprises a fan forward indicating circuit and a fan reverse indicating circuit; the air-door manual control analog circuit comprises an air-door opening indicating circuit and an air-door closing indicating circuit. According to the axial-flow-fan training model, operational experiences and hand feelings of workers are conveniently cultivated, and the axial-flow-fan training model is widely suitable for all coal mines.

Description

technical field [0001] The invention relates to a training model of an axial fan. Background technique [0002] The main ventilator in the current coal mine mostly adopts the axial flow fan with adjustable blades. Its control logic is relatively complex and the degree of automation is high. The operation of starting, stopping and reversing all realizes one-button operation. In accordance with the requirements of the "Coal Mine Safety Regulations" and "Mine Quality Standardization", the main ventilator in the mine is turned down and inspected once a month. Daily operation and maintenance frequency is low. [0003] According to relevant regulations: if the main ventilator stops for more than 10 minutes, it is a major electromechanical accident. Due to the particularity and importance of the ventilation system in mine production, in actual production, the main ventilator cannot be simulated and operated on site. There are few on-site operation opportunities for employees, lo...
