The diesel generator block heater can help the diesel generator start normally at low temperatures. The colder the weather, the more difficult it is for diesel generators to start, because the temperature is low, the viscosity of the oil increases, the friction resistance of various moving parts increases, and the starting speed decreases, making it difficult for diesel generators to start. In addition, the storage capacity of the battery will also decrease as the temperature drops, which will also cause the generator to be difficult to start.
Diesel Generator Set Heater Three Types:
1. Water jacket heater. When the mains single-phase voltage is correctly connected, it is used to automatically heat the coolant of the unit. When the unit is in the standby state, the device automatically detects the temperature of the coolant, and when the temperature is lower than the limit set by the factory, it will automatically power on for heating. When the temperature rises to about 50°C, the heating will be automatically stopped. Jacket heaters are necessary for units used in areas where freezing may occur. The power supply of the water jacket heater of the unit is AC220V.
2. Air preheater. Its function is to heat the air entering the combustion chamber in order to increase the success rate of starting when the unit is started. The air preheater will automatically stop working when the unit starts to run normally and the starter motor has exited. The power supply of the air preheater is generally the starting battery of the unit.
3. Anti-condensation heater. When the ambient humidity of the diesel generator set is high, an anti-condensation heater should be installed additionally. Its power source is generally the unit starting battery.
This article focuses on the use of water jacket heaters. The water jacket heater is made of high-quality stainless steel and equipped with a constant temperature control device. It has the characteristics of a beautiful appearance, corrosion resistance, and long life. It can be used for preheating and warming up to prevent freezing. So how should this heater be used? The following is a detailed explanation for you:
1. Preheating
For the unit with a preheater, before starting, the person can decide whether to perform the preheating operation according to the ambient temperature, and the control panel with the preheating button can control the engine to start and heat up to achieve the purpose of preheating.
2. Power on the battery
Turn the key switch of the control panel from OFF to ON position, and observe that the background light of the instrument on the panel is on, indicating that the control panel is powered on, and at the same time, the fuel of the unit is on, and the controller of the unit with electronic speed control or EFI is also on. working status.
3. Unit start
Some unit control panels have an idle speed/full speed switch, and users can choose whether to start at idle speed or start at full speed at one time according to actual needs.
Diesel Generator Block Heaters Operation Tips:
1. When the unit is running, be sure to stop the water jacket heater, otherwise, the heater may be burned out. The relevant control functions have been designed on the control circuit of the matching heater installed, and the power supply of the heater will be automatically cut off when starting up.
2. In order to prolong the service life of the starter battery and the starter motor, it is advisable to control the time to start the unit within 5-10 seconds at a time. If the first startup is unsuccessful, you can pause for a corresponding period of time before proceeding to the second startup procedure.
3. The manual maintenance valve on the heater pipeline must be in the open state.
