If the oil pressure and fuel pressure are insufficient, the diesel generator will not operate. At present, most high-power medium-speed diesel generators have a relatively complete monitoring and detection system to monitor some important parameters (such as temperature, pressure, etc.). Diesel generators, once these parameters exceed the set range, will emit sound and light alarm or automatic stop. Diesel generators are equipped with temperature monitoring of cylinder exhaust, turbine exhaust, main bearing, generator stator, cylinder liner water and lubricating oil, as well as pressure monitoring of fuel oil, starting air, lubricating oil, raw water, liner water, nozzle water and intake. These temperature and pressure monitoring, alarm and safety shutdown systems consist primarily of CMR424 and CMR524 units mounted on the control panel. Does temperature and pressure control play a key role in the operation of diesel generators? There are many temperature sensing components in the operation of diesel generators, but they can be roughly divided into two categories: thermal resistance (PT100) and thermocouple (nichcr/Nichal). According to the change of the resistance value of the thermal resistance sensor and the change of the thermoelectric potential of the thermocouple sensor when the temperature changes, the signal is transmitted to the CMR424 system for conversion comparison, printing, display and alarm or tripping. The transmission of pressure is mainly to transmit the signal to the CMR424 system for comparison, printing, display and alarm or tripping action.
