    摘要: A method for regulating the flow of a viscosity-dependent liquid in a graphic process, including a pump (5) configured for pumping a viscosity-dependent liquid (3) from a first container (4) and to a graphic printing machine (1), and wherein the viscosity of the liquid (3) affects operation of the pump (5), a sensor (8) connected with the pump (5) and which is configured to measure at least one of the operational parameters of the pump (5), and a controller (9) connected with the sensor (8) and which is configured to analyze the data from the sensor (8). The controller (9) determines the viscosity of the liquid (3) from the measured operational parameters of the pump (5) and generates a control signal (17) from the measured viscosity, based on which the viscosity of the liquid (3) pumped through the pump (5) can be adjusted.

    摘要: It is intended to prevent ink from leaking through the ink outlet of the ink rail while the printing press is at halt. To achieve this object, a motor control section 40 shown in FIG. 4 controls the rotation of a stepping motor 15 driving a plunger 13 and, every time the stepping motor 15 is stopped, the outer circumference 13c of the plunger 13 except a cut portion 13a blocks at least a discharge port 18, thereby enabling the pressure ink invading from an intake port 17 into the main hole 11 of a cylinder 12 to press the plunger 13 against the discharge port 18 opening into the inner circumferential face of the main hole 11.
