Impellent Tramcar Machine Hydraulic and Electrical Control System
This essay will introduce a impellent tramcar machine, used for mining enterprises’ vertical shaft hoisting transportation system, which is used to put tub into the cage, or pull it from the cage. The mechanical impellent tramcar machine are widely used at present, it rely on the direct-drive motor, there are two types of traction, one is towed by the sprocket and chain anther is towed by the reel and wire, whatever we use which type, both the traction drive components are exposed, the environment dust will lead to poor lubrication, running noise, shock and vibration significantly, poor stability. To overcome the mechanical impellent tramcar machine of these shortcomings, developed the hydraulic impellent tramcar machine, the hydraulic cylinder as the executing agency, the programmable logic controller to achieve electrical control, designed hydraulic systems and PLC control program, analyzed the impellent tramcar machine Structure and working principle, point out that the use of programmable logic controller, programming is easy, flexible, programmable logic controllers cater to the industrial production sites, with great anti-interference ability, hydraulic drive compact, smooth and high reliability.
