Water-jet propulsion pump device with telescopic water inlet flow channel and implementation method thereof

Abstract

The invention discloses a water-jet propulsion pump device with a telescopic water inlet flow channel and an implementation method thereof, and belongs to the field of ship engineering. The device comprises a water-jet propulsion pump and a water inlet flow channel. The water inlet flow channel comprises a near-nozzle water inlet flow channel and a near-water inlet flow channel, the near-nozzle water inlet flow channel is located at a water inlet end of the water-jet propulsion pump, and the near-water inlet flow channel is movably connected with a ship plate; the device is provided with a telescopic water passing part, one end of the telescopic water passing part is fixedly connected with a near-nozzle water inlet flow channel, and the other end of the telescopic water passing part is connected with the near-water inlet flow channel; and the telescopic water passing part moves upwards or downwards in the near-water inlet flow channel so that the water inlet flow channel is telescopic,a draft T' reaches a proper range, the stable operation of the water-jet propulsion device is realized, and the water-jet propulsion pump device and the method have wide market and application prospects in the design and operation of propulsion ships and high-speed boats.

Description

technical field [0001] The invention relates to a water jet propulsion pump device with a retractable water inlet channel and a realization method thereof, belonging to the field of ship engineering. Background technique [0002] The water inlet channel is one of the important components of the water jet propulsion pump device, and the optimization of its performance has always been the focus of research. For a ship loaded with cargo or personnel, due to the change of load, its draft is different, so the draft T of the suction port of the water jet propulsion pump device is not in the ideal design range, resulting in unstable operation of the water jet propulsion pump device. The traditional water inlet flow channel is often of fixed length, which cannot effectively adjust the draft. This patent invents a new type of retractable water inlet flow channel to solve the problem of safe and reliable operation of the water jet propulsion pump device that plagues the shallow draft....

For a ship loaded with cargo or personnel, due to the change of load, its draft is different, so the draft T of the suction port of the water jet propulsion pump device is not in the ideal design range, resulting in unstable operation of the water jet propulsion pump device

The traditional water inlet channel is often of fixed length, which cannot effectively adjust the draft. This patent invented a new type of retractable water inlet channel to solve the problem of safe and reliable operation of the water jet propulsion pump device that plagues the shallow draft.
