Abstract

The invention discloses an energy-saving rotating-speed measuring device of a ship main engine. The energy-saving rotating-speed measuring device comprises a navigational speed measurement device, a fuel consumption measuring device connected to a ship main engine, and a fuel consumption integrating instrument. The fuel consumption measuring device is used for calculating a fuel consumption value; and the fuel consumption integrating instrument connected with the fuel consumption measuring device and the navigational speed measurement device is used for calculating fuel consumption of a ship at a unit distance. The navigational speed measurement device is a log device or a GPS terminal. The fuel consumption measuring device consists of an oil inlet tube flowmeter and a oil return tube flowmeter; and the oil inlet tube flowmeter and the oil return tube flowmeter are connected to an oil inlet and an oil outlet of the ship main engine. The oil inlet tube flowmeter and the oil return tube flowmeter are provided with signal sender units respectively; and the signal sender units are connected with the intelligent fuel consumption integrating instrument electrically; and a server is connected between the ship main engine and the fuel consumption integrating instrument. Therefore, the fuel consumption state of the diesel engine in a ship sailing state can be measured and recorded accurately, so that the ship can determine an optimal energy-saving navigation speed. The demand of rapid and accurate measurement and recording of fuel consumption of the host of the ship at the unit distance can be satisfied.

Description

technical field [0001] The invention relates to an energy-saving speed detection device in shipping, in particular to an energy-saving rotational speed measurement device for a main engine of a ship. Background technique [0002] Fuel-consuming equipment on ships mainly includes ship main engines, diesel generators, boilers and other equipment. Among them, the most important fuel-consuming equipment in ship navigation is the main engine. Ship fuel consumption mainly occurs when the ship’s main engine is running to provide navigation power to the ship. In theory, there is an optimal coordination point among the ship, main engine, and propeller, and the unit fuel consumption rate of the ship is optimal at this time. However, due to the influence of the specific navigation environment, such as the cargo capacity of the ship, the draft of the ship, ocean and meteorological factors, etc., during the actual navigation of the ship, the theoretical ship, main engine, and propelle...

Problems solved by technology

However, due to the lack of practical measurement and calculation methods, in the daily management of the main engine speed of ships in operation, shipping companies only stipulate one main engine speed for sea-going ships regardless of no-load or heavy load; Rotational speed, the rotational speed of a launching machine

This management method has low accuracy and poor real-time performance, which is not conducive to the adjustment of the speed of the main engine within the speed range of the main engine according to the actual navigation conditions, and it is impossible to achieve shipping production at an accurate energy-saving speed.

However, the optimal fuel consumption speed selection methods of other means of transportation such as automobiles and airplanes are less different from the theoretical value, and are less affected by external disturbance factors, so it is easier to calculate, but considering the actual situation of ship navigation, Difficult to apply it to ship navigation
