Function and failure-prone elimination of each dredger valve group (1)

Function and failure-prone elimination of each dredger valve group (1)

 The functions of the various valve groups of dredgers and the sweeping-out of easy-to-perform valve states:
  Left and right traverse valve group: This valve group is used to control the dredging vessel's right and left traverse winch drums, respectively. There is an electro-hydraulic reversing valve on the valve block. If the dredger traverses the winch during operation, if it does not move, it may be that the electro-hydraulic reversing valve is formed (perhaps the solenoid valve is dead) and the solenoid coil is damaged. At the moment the valve removed, cleaned with diesel fuel, and then repeat the installation position in accordance with the direction removed (Note: there may be a hydraulic drive motor dredger winch internal damage and other problems) the manipulation of an operation valve The left traverse and right traverse rocker switch or button manipulation on the stage.
  Bridge crane winch valve group: This valve group is used to control the rise and fall of the dredger turret. The valve group is composed of an electro-hydraulic reversing valve and a balancing valve for controlling and lifting. If the draught winch does not move during the lifting of the dredger turret, it may be that the electro-hydraulic directional valve is formed (perhaps the solenoid valve is dead, the coil is damaged) and the directional valve will be removed at the moment ( Pay attention to the direction and direction. It can be re-installed with clean diesel. The control of the valve group is controlled by the reamer rocker switch or button on the dredger operating platform.
  Positioning pile valve group: This valve group is used to control the rise and fall of left and right positioning piles of dredgers. The valve group is composed of an electro-hydraulic reversing valve that controls the rise of the left and right positioning piles, a solenoid valve that controls the lowering of the left and right positioning piles, and a hydraulically-controlled check valve. If the left and right piles of the dredging ship do not rise, then it may be the formation of the electro-hydraulic directional valve or the hydraulic check valve, which is not tightly closed (unsealed). . The valve or pilot-operated check valve will be removed at this moment. Use a clean diesel cleaner (pay attention to the direction of disassembly must pay attention to the direction of the direction) to repeat the installation. The control of the valve group is controlled by the left and right positioning pile rocker switches or buttons on the dredger operating table. The slow release of the tail pile is controlled by the needle-saving valve at the tail of the hull.
