Abstract

The invention discloses a failure alarm circuit for an emergency stop solenoid valve loop of a diesel engine. The failure alarm circuit consists of a stop power supply, a stand-by power supply, a first current type relay normally-closed contact, a second current type relay normally open contact, a second current type relay normally-closed contact, a third current type relay normally open contact, a voltage type relay coil, a first current type relay coil, a second current type relay coil, a third current type relay coil, an emergency stop solenoid valve, a stand-by solenoid valve, an alarm power supply, a voltage type relay normally-closed contact, a first alarm lamp and a second alarm lamp. The failure alarm circuit is simple, and can respectively alarm and carry out timely self-protection for power failure caused by failure of the stop power supply and the faults of the emergency stop solenoid valve so as to ensure the normal work of the emergency stop solenoid valve loop. The invention further provides an alarm method for the failure alarm circuit for the emergency stop solenoid valve loop of the diesel engine, wherein alarms for different fault problems are given off through different alarm lamp lightening modes.

Description

technical field [0001] The invention belongs to the technical field of diesel engine safety protection, and in particular relates to a diesel engine emergency stop electromagnetic valve circuit failure alarm circuit and an alarm method thereof. Background technique [0002] The shipbuilding industry is a modern comprehensive industry that provides technical equipment for water transportation, marine development and other industries. It is also a labor-, capital-, and technology-intensive industry that plays a strong role in driving the development of upstream and downstream industries such as electromechanical, steel, chemical, and shipping. As the heart of the entire ship, ship power is an important guarantee for the vitality and endurance of the ship. Diesel engine has a series of advantages such as wide power coverage, high efficiency in the whole operating range, good economy, simple power device, small size and weight, and low life-cycle cost. It is widely used in conve...
