The invention discloses an inflow pipeline of a water jet propulsion device of an integrated cooling oil tank and a hydraulic control system and belongs to the field of inflow pipelines. The inflow pipeline comprises an arc-shaped pipe, a spindle pipe, a transom board, two cooling oil tank side plates, a cooling oil tank cover plate and oil openings. The cooling oil tank cover plate, the two cooling oil tank side plates, the outer wall of the arc-shaped pipe, the outer wall of the spindle pipe and the transom board define the closed cooling oil tank. Two oil openings in the cooling oil tank communicate with a hydraulic pump oil tank and an oil opening of a two-position four-way reversing valve correspondingly, so that when a hydraulic pump controls a hydraulic oil cylinder to work, hydraulic oil flowing back from the hydraulic oil cylinder enters the cooling oil tank first through one oil opening and then flows back to the hydraulic pump oil tank from the other oil opening, so that the hydraulic oil flowing into the cooling oil tank can be cooled by water flow in the arc-shaped pipe. Due to the fact that cooling is conducted through the water flow flowing past in the arc-shaped pipe directly, a cooling water source does not need to be provided, and production cost is reduced. Meanwhile, due to large water flow in the arc-shaped pipe, the heat dissipation effect is better.
Description
technical field [0001] The invention relates to the field of inflow pipelines, in particular to an inflow pipeline and a hydraulic control system of a water jet propulsion device with an integrated cooling oil tank. Background technique [0002] The water jet propulsion device is a kind of ship propeller, which provides the thrust of the ship's movement through the reaction force generated by the jet of water. An inverted bucket scoop is arranged at the water nozzle of the water jet propulsion device, and its function is to change the direction of the jet water flow. The reverse bucket scoop is controlled by the hydraulic system to realize the forward and reverse functions. The hydraulic system will generate a lot of heat during frequent work, so the hydraulic system needs to be cooled. [0003] In the existing water jet propulsion device, a set of serpentine cooling device is installed in the oil tank of the hydraulic pump, and the device has two external interfaces, one o...
