Miniature ship engine oil nozzle checking device

Abstract

The embodiment of the invention provides a micro ship engine oil nozzle checking device. The micro ship engine oil nozzle checking device comprises an oil cylinder piston; the oil cylinder is connected with the oil cylinder piston and is used for driving the oil cylinder piston to move; the rack is connected with the oil cylinder piston and is used for moving under the driving of the oil cylinder piston; the gear is meshed with the rack and is used for rotating under the driving of the rack; the gear revolution counter is arranged on the gear and is used for counting the revolution of the gear so as to calculate the fuel injection quantity of the fuel injector; the first oil liquid conveying structure is connected with the oil cylinder and used for conveying oil liquid in the oil spraying nozzle to the oil cylinder so that the oil cylinder can drive an oil cylinder piston to move. And the second oil liquid conveying structure is connected with the oil spraying nozzle and used for conveying oil liquid to the oil spraying nozzle. According to the micro ship engine fuel injection nozzle checking device provided by the embodiment of the invention, the whole fuel injection nozzle tester device is small in volume, can be directly arranged in a ship, and can be used for checking and checking the fuel injection nozzle at any time.

Description

technical field [0001] The embodiment of the present application relates to the technical field of ship manufacturing, and in particular to a micro-ship engine fuel injection nozzle verification device. Background technique [0002] For many large and medium-sized ships, fuel injectors (nozzles) are often used to provide fuel for their engines. Whether it is a single-cylinder or multi-cylinder marine engine, all fuel must be injected into the combustion chamber through its own injector to complete the required power. Therefore, the fuel injection accuracy of each injector is particularly important, which is directly related to Whether synchronous, equal and accurate fuel can be obtained in each cylinder, so as to ensure the coordinated movement of each combustion unit of the engine, so that the ship can obtain sufficient driving force. However, due to problems such as oil purity, plunger wear, and deformation, the fuel injectors often suffer from fouling, clogging, and poor...

AI Technical Summary

Problems solved by technology

However, due to problems such as oil purity, plunger wear, and deformation, the fuel injectors often suffer from fouling, clogging, and poor airtightness, resulting in uneven spray volume, which seriously affects the power output of marine engines.

[0003] For this reason, the above-mentioned problems are solved by adopting the fuel injector tester device. However, the fuel injector tester device is relatively large in size and can only be installed in a dedicated workshop. During the calibration, the complete set of fuel injector assemblies must be disassembled and sent to the above-mentioned fixed factory for calibration, which will result in time-consuming, inconvenient use, and affect the calibration effect
