The lubrication system is automatic timing, pointing directly to the lubricating oil sprayed onto the chain pins so that it get a good lubrication. Start time lubrication system pump or solenoid valve to the oil by the time delay relay in the control cabinet control (PC control by PC internal time relay control). (13) The safety devices: escalator is an important tool of public transport, Qingyun escalator, safety is paramount. With the application of PC and escalator manufacturers, automatic fault alarm, automatic display, automatic fault analysis can be achieved. According to (EN) regulations escalator safety standards, escalators must have. The main parameters and parts of the escalator 1. The main parameters (1) rated speed (Y /): Cascade speed under no-load conditions (m / s). Typically 0.5m / s, 0.65m / s and 0.75m / s. (2) tilt angle (α): the maximum angle with the horizontal plane running cascade configuration, escalator supply, typically 30 ° or 35 °. (3) lifting height (H): vertical on the basis and starting point of the escalator under the height difference (m). (4) Step width (B): Cascade nominal width (mm). (5) rung horizontal section (L): the level of imports from the escalator at running (mm). When v = 0.50m / s, L≥800mm; when v≤0.65m / s when, L≥1200mml when v≤0.75m / s when, L≥1600mm.
