Abstract (en)
[origin: WO2014195082A1] The invention relates to a method for operating a device (1) for conveying a fluid by means of a conveying pipe (2) which can be divided into a suction pipe section (4) from at least one tank (6) to at least one pump (3) and into a pressure pipe section (5) from the pump (3) to at least one injector (7), and has at least one pressure sensor (8) on the pressure pipe section (5). In a step A) of the method an activation of the device is detected. In a step B) of the method the conveying pipe (2) is filled with the fluid by an operation of the at least one pump (3) having a conveying direction (9) from the at least one tank (6) to the at least one injector (7), and a complete filling of the conveying pipe is detected on the basis of at least one dramatic pressure increase (10) at the at least one pressure sensor (8). In step C) an operation of the pump (3) and a provision of fluid at the injector (7) take place. In step D) a deactivation of the device (1) is detected. In step E) a partial emptying of the conveying pipe (2) takes place by back-suction of the fluid by means of an operation of the at least one pump (3) contrary to the conveying direction, wherein the emptying is stopped when the pressure measured at the least one pressure sensor (8) corresponds to an ambient pressure (12).
