Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] 1. Equipment composition and principle

[0022] Before introducing the risk warning method of the present invention in detail, a brief introduction will be made to the composition and working principle of the electric pump system. The electric pump is powered by the power distribution box, and the magnetic starter (if it is controlled by a remote control device, it should be connected to the remote control device) is connected to control the motor to drive the pump equipment to run. It works as figure 1 shown. Due to the different degrees of ship automation, the technical requirements for the pump control system are also different. Generally, the following requirements are required: each group of pumps can be remotely started and stopped in the centralized control room; the pumps can be controlled locally; the pump automatic control system sho...

Abstract

The invention relates to a risk early warning method for electric pump systems of ships, which comprises the following steps: when the electric pump system fails to work, the fault mode is determined to be a water-delivery pump stopping mode, a water-delivery pump start failure mode, a daily fresh and sea water pump stopping mode, a daily fresh and sea water pump (or spare pump) start failure mode or a daily fresh and sea water pump automatic conversion failure mode according to information on various devices collected by sensors arranged on various measuring points of the ship electric pump system and information on device operation and failure obtained by manual inspection; then risk early warning flow is determined according to the generated fault mode, and risk early warning is given according to corresponding diagnosis flow. When put into use, the method can provide proper basis for daily maintenance of the electric pump systems of the ships.

Description

technical field [0001] The invention belongs to the field of equipment state monitoring and risk early warning, and relates to a ship equipment risk early warning method. Background technique [0002] In order to ensure the safety of the ship's navigation, the main equipment of the ship's electric pump system is monitored and diagnosed, and maintenance measures are given according to the diagnosis results to solve the existing problems, so as to ensure the safe operation of the ship and avoid the inspection of the ship by the port state. It can also reduce the cost of ship maintenance and improve the competitiveness of ship management companies. Due to the many indicators involved in the risk warning of the ship's electric pump system, and the relationship between the various influencing factors is intricate, at present, domestic and foreign shipping companies mainly rely on the technical experience of risk warning and evaluation personnel to implement risk warning and statu...
