Abstract

The invention discloses a diesel generator emergent stop electromagnetic valve loop failure warning circuit. The warning circuit consists of a stop power supply, a spare 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 emergent stop electromagnetic valve, a spare electromagnetic valve, a diesel generator, an AC/DC module, a voltage type relay normally closed contact, a first warning lamp and a second warning lamp. The warning circuit is simple, and can respectively perform the warning and timely self-protection for the failure of the stop power supply of an emergent stop electromagnetic valve loop and the failure of the emergent stop electromagnetic valve. The invention further discloses a diesel generator emergent stop electromagnetic valve loop failure warning method; and different failure problems are respectively warned through different warning lamp lightening modes.

Description

technical field [0001] The invention belongs to the technical field of diesel generator safety protection, and in particular relates to a diesel generator emergency stop electromagnetic valve circuit failure alarm circuit and an alarm method. 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 generator is a small power generation equipment, which refers to the power machinery that uses diesel oil as fuel and diesel engine as the prime mover to drive the generator to generate electricity. The whole unit is ge...
