(1) selection of diesel engine oil has good low temperature performance of this kind of low temperature oil viscosity is small, the friction between the start of good lubrication, small resistance, to start. Multistage oil used at present, such as low temperature fluidity better before 15W/40W the smaller the number of oil. Therefore, the use of 10W or 5W oil is recommended at low temperature.
(2) the storage battery can be kept warm when the low temperature performance battery is necessary, so that the battery can be charged under the low temperature condition and have enough output current, thus improving the power of the starting system.
(3) the cold starting liquid filling.
(4) flame preheating.
(5) circulating water heating system (also known as the fuel heater heating system).
(6) other preheating methods, in addition to the above preheating methods, can also be started at low temperature by hot water preheating method, steam preheating method, electric preheating method and so on. ,
When operating, it is necessary to ensure that the low voltage line switch of the box type substation is in the disconnected position, the unit oil, water, and the pre oil supply switch, start the electric pre oil supply pump (or move the oil pump of the hand machine). After the main oil channel pressure reaches the 100kPa starting value, press the starting button "Start". After the start of the unit, the "page" button can be pressed and the changes of various technical parameters in the engine operation can be checked through the liquid crystal display screen. After the successful start idling warm-up, when the oil temperature, water temperature reaches 40 DEG C, can be accelerated and loading. Press or adjust the control panel on the deceleration knob set frequency, to slightly higher than the rated frequency. Adjust the tuning knob of the voltage regulator on the control panel to make the AC voltmeter at the 400V position and press the "I/O" button. At this time, the related data can be monitored in the "generator" bar on the SCADA monitoring interface of the station control room, and the unit will supply the load to the load.
