Jul. 16, 2025

When using diesel generator sets for a long time, it is essential to know the functions of the emergency shutdown device and the alarm switch.

(1) Emergency Shutdown Device of Diesel Generator Sets

The emergency shutdown device of Shangchai diesel generator sets can be operated electrically, mechanically, or hydraulically. Users should be familiar with the shutdown mode and location of the shutdown device installed on their diesel generator engines, the conditions for activating various shutdown devices, and the reset steps required before restarting.

 

The working principles of all electric shutdown devices are similar. When a certain critical operating condition occurs, a switch is activated to stop the engine. The shutdown device needs to be reset before the engine can be restarted.

 

The shutdown device should be inspected by the company's personnel every 1000 working hours. The engine unit staff can test the hydraulic - mechanical shutdown device every 500 working hours. Generally, the emergency shutdown device should not be used during normal shutdowns. The cause of the sudden shutdown must be identified, and necessary repairs should be carried out.

 

(2) Alarm Switch of Diesel Generator Sets

The set temperature, pressure, or liquid level critical values when the alarm of Shangchai diesel generator sets is activated are more stringent than those for emergency shutdown, that is, the alarm is triggered in advance. The purpose of the alarm is to warn the operator of an impending unsafe situation, and corrective measures must be taken to prevent engine damage.

 

After the alarm is triggered, necessary corrective measures should be taken before the situation turns into an emergency. Each alarm switch is connected by wires to an indicator light, a bell, or a speaker. The alarm continues until the fault is eliminated, and then the indicator light goes out, and the bell or speaker stops ringing. To prevent the alarm from sounding during the repair process, a two - way switch and a red indicator light can be installed. When the switch is toggled to cut off the alarm, the red light lights up. If the switch remains in the "OFF" position after the repair, the red light continues to shine, indicating that the engine is not in a protected state.
