    摘要: A nozzle cleaner includes: a cleaning tank which stores a cleaning solution; a first conductive member that is disposed to be immersed into the cleaning solution stored in the cleaning tank when the nozzle is cleaned; an ultrasonic wave generating mechanism which is disposed so that at least a part of a second conductive member is immersed into the cleaning solution stored in the cleaning tank when the nozzle is cleaned and generates an ultrasonic vibration in the cleaning solution stored in the cleaning tank; a first voltage control unit which controls a potential applied to the first conductive member; and a second voltage control unit which controls a potential applied to the second conductive member, wherein the first voltage control unit applies a second potential V2 higher than a first potential V1 applied to the nozzle when the nozzle is cleaned to the first conductive member.

    摘要: An apparatus for underwater pipes comprising an ultrasound emitting system and at least one ultrasound receiving transducer is lowered into he marine environment. During an inspection phase, an ultrasound inspection source of the ultrasound emitting system and the receiving transducer are disposed on each side of the pipe. The inspection source is activated, and an ultrasound signal captured by the receiving transducer is recorded. In response to the observation of an anomaly in the ultrasound signal captured by the receiving transducer, a power source of the ultrasound emitting system is then coupled to the pipe at the aforementioned location, and the power source is activated in order to destroy the obstruction.

    摘要: An automated method of cleaning the pipes of a plate washing system is provided. The plate washing system includes at least one manifold having a plurality of pipes configured to be provided within wells of a plate in order to wash the wells, an ultrasonic transducer mounted to a tank, and a control system. The plate washing system also includes sensors to sense the position of the pipes relative to plate and the tank, and the fluid level within the wells of the plate. The method includes dispensing fluid to the tank, submerging the tips of the pipes within the fluid, activating the ultrasonic transducer in order to vibrate the fluid, and aspirating the fluid from the tank. The control system may initiate a cleaning operation at the request of the user, at a scheduled interval, or when the level sensing system detects a decrease in instrument function.

    摘要: A method for cleaning the U-tube of the measurement cell of a densimeter, the measurement cell including an isothermic enclosure defining a measurement chamber closed by a stopper surrounded by a resilient seal, a U-tube extending inside the measurement chamber for containing a sample, the U-tube secured to the stopper at a base of the U-tube which includes free ends projecting outwardly from the measurement chamber to permit injection of the sample via an injection opening and evacuation of the sample via an evacuation opening, and means for causing the U-tube to vibrate. The method comprises, following a step of analyzing a sample, injecting a rinsing solvent into the injection opening of the U-tube, and subjecting the stopper to ultrasonic waves.
