We all know that the use of diesel generator sets is affected by altitude. The higher the altitude, the lower the local air pressure. As the altitude increases, the ambient temperature is also lower than that in the plain area. When the temperature drops by about 0.6℃, the user should take auxiliary starting measures corresponding to low temperature starting when using it. When starting at low temperature, the user must pay attention to the following matters:
1) Control the startup time
When the diesel generator set is started at a low temperature, the starter can continuously drive the diesel engine to rotate for more than 10S; when it fails to ignite three times in a row, it should be stopped for 2 to 3 minutes before starting. If it still fails to ignite after restarting 2 to 3 times, check whether there is air or blockage in the oil circuit, and whether the air filter is blocked.
2) Pay attention to safety when using low temperature starting fluid
The low-temperature starting fluid container should be installed in a cool and ventilated place, away from high-temperature heat sources, and it is forbidden to approach open flames to prevent explosions from hurting people. The low-temperature start-up liquid is flammable and has anesthetic properties. It should be sealed and stored in a cool and ventilated warehouse with low temperature. It should not be stored in the open air. Personal safety should be paid attention to during storage. Do not add low temperature starting fluid into the fuel tank to avoid air lock.
3) Oil heaters should be correctly selected when using fuel oil
When using an external forced circulation fuel heater, gasoline cannot be used as fuel, and light diesel oil (or kerosene) of an appropriate brand should be selected according to the ambient temperature of the machine. Under the temperature, the diesel oil does not freeze or wax, which prevents the oil supply circuit from being blocked.
4) Start with less trailer
Try not to start the diesel engine by the method of starting the trailer, because the diesel engine is not preheated and the oil viscosity is high, and the starting of the trailer will lead to increased wear and tear of various components due to poor lubrication.
