Embodiment Construction

[0046] The working principle of the speed control system is firstly described as follows:

[0047] Engine speed is controlled by a Woodwater PSG governor mounted on the control side, which controls the position of the fuel injection pump rack through the fuel control lever. The fuel injection pump is installed upside down in the body under the camshaft. The fuel pump rack is connected to the fuel control lever installed in the body through a clamping block and a short tension spring, and the control lever is loaded in a pair of rollers for axial movement. The movement of the fuel control lever is transmitted to the gear body of the fuel pump through the clamping block that is forced to lock in the direction of full load, and the direction of "parking" depends on the action of the tension spring. This structure allows one or more fuel injection pumps to be stuck At this time, the oil pump rack can be pulled in the direction of "parking", so that the engine can be parked under ...

Abstract

The invention relates to a ship rotation speed control system risk pre-warning method. When the unusual situation of the ship rotation speed control system is found, the risk pre-warning is carried out according to the steps as follows: step 1: according to all equipment information collected in real time by sensors which are arranged at all the measurement points of the ship rotation speed control system, and the equipment running and failure information obtained manually, one failure mode of the failure modes as follows are determined: stopping failure mode due to the unstable starting of the diesel engine, stopping failure mode due to the sudden shutdown of the engine, failure mode caused by not achieving rated rotation speed, diesel engine run-away failure mode, and engine idle-car / rotation speed fluctuation failure mode; step 2: the risk pre-warning flow is determined according to the happened failure mode; subsequently, the risk pre-warning is executed according to correspondingdiagnosis process. The method of the invention can provide reasonable basis for the daily maintenance and curing of the ship rotation speed control system after being used.

Description

technical field [0001] The invention belongs to the technical field of faulty equipment diagnosis, and relates to a risk early warning method for ship equipment. Background technique [0002] In order to strengthen ship management, ensure the safety of ship navigation, and improve the safety performance of the ship speed control system, the main equipment of the ship speed control system, such as PSG governor, fuel joystick, electric speed control motor, pneumatic positioner, torsion spring, emergency stop Evaluate the actual operating status of the sleeve, etc., evaluate the integrity rate of the ship's speed control system, and arrange the overhaul and maintenance of key equipment according to the evaluation results, solve the existing problems, and formulate an effective ship speed control system status Improve the plan, strengthen the control and management of the ship's speed control system, and do a good job of maintenance to ensure the safe operation of the ship, avoi...
