- the nozzle heads are advantageously rotatably mounted so as to direct the high pressure water jet at an angle of 30° to 150°.
- the manipulator body and stand in the device for cleaning the heat-exchange tubes of the steam generator can be equipped with limit switches.
- the auxiliary equipment in the steam generator heat exchange tube cleaning device consists of a high pressure pump, associated high pressure hoses, suction pumps, associated suction nozzles and suction hoses, a receiving tank, intermediate vacuum pumps, filters and a storage tank.
- the manipulator can be equipped with a pneumatic brake system, and the coordinate head preferably contains at least one eddy current sensor mounted on a spring suspension.
- Fig. 1 shows a diagram of the place of work on cleaning
- Fig. 2 shows a general view of the manipulator assembly with the knee
- Fig. 3 shows a general view of the assembled manipulator with a knee and a knee of the actuating units.
- the device for cleaning the heat exchange tubes of the steam generator of a nuclear power plant with high-pressure water jets contains a manipulator 1 installed for movement and fixation in a vertical corridor 2 passing between bundles of heat exchange tubes 3.
- the manipulator 1 is connected to a lift (not shown in Fig.) to enable its delivery and placement inside the steam generator in the work area. To ensure the accuracy of movement of the manipulator 1, the device is equipped with remote control and video monitoring.
- High-pressure water jets are supplied through a nozzle (not shown in Fig.) mounted on the manipulator 1 and connected to the high-pressure hose 4.
- the device To carry out the movement of the manipulator, assess the state of the metal of the heat exchange tubes of the steam generator, determine the places for cleaning and the process of cleaning the heat exchange tubes of the steam generator, the device is equipped with means of remote control and video monitoring (not shown in Fig.).
- the device for cleaning the heat exchange tubes of the steam generator is also equipped with a guide mounting frame 5, a coordinate head, as well as a sludge removal unit from the bottom of the steam generator and auxiliary equipment (not shown in the figure).

- the manipulator 1 can be equipped with a pneumatic brake system, and the coordinate head preferably contains at least one eddy current sensor mounted on a spring suspension.
- the operation of the device for cleaning the heat-exchange tubes of the steam generator of a nuclear power plant with high-pressure water jets is carried out as follows.
- the device for cleaning the heat exchange tubes of the steam generator is lowered inside the steam generator between the bundles of heat exchange tubes, mounted above one of the selected cells of the steam generator and connected to the high pressure pump.
- the manipulator 1 moves along the guide mounting frame 5, while the control and selection of the speed mode of its movement is regulated by a pneumatic brake system.
- Jets of water under high pressure cover both parts of the sectors of pipes 3 located opposite each other along the corridor of the annular passage.
- the video monitoring system ensures accurate placement and alignment of each row of pipes 3 and pipe strings.
- the manipulator 1 is driven by a servo drive, which includes position and speed sensors and a drive control unit that automatically maintains the necessary parameters on the sensor (and, accordingly, on the manipulator 1) according to a given external value.
- a servo drive which includes position and speed sensors and a drive control unit that automatically maintains the necessary parameters on the sensor (and, accordingly, on the manipulator 1) according to a given external value.
- the manipulator 1 When reaching the extreme point of movement, the manipulator 1 returns to the starting point of the movement or goes down by 5-10 mm (depending on the selected mode).
- the specified cleaning mode occurs in automatic mode until the lowest point of the bundle of heat exchange tubes 3 is reached.
- manipulator 1 work is performed remotely when the manipulator 1 moves from the upper row of pipes 3 of the steam generator to step-by-step sequence until all pipe segments 3 are covered in directions with different flushing orientations.
- the cleaning process is possible in different directions of water jet supply from 30° to 150° with the nozzle moving along the annular vertical corridor. Washing is controlled by video surveillance. Depending on the quality of cleaning, the process can be repeated until the desired result is achieved.
