瓦斯气发电机组的低温启动方式

来源:http://www.huannengpower.com   发布于:2018-06-19

(1)选用低温性能好的柴油机油这类机油低温黏度小,各摩擦副间润滑好,启动阻力小,利于启动。目前使用的多级油,如15W/40W前的数字越小则机油的低温流动性越好。因此,低温时推荐使用10W或5W机油。

(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)采用低温性能好的蓄电池 必要时可对蓄电池进行保温,以保证其低温条件下能正常充电且有足够的输出电流,从而提高了启动系统功率。

(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)加注冷起动液。

(3) the cold starting liquid filling.

(4)火焰预热启动。

(4) flame preheating.

(5)循环水加热系统(也称燃油加热器加热系统)。

(5) circulating water heating system (also known as the fuel heater heating system).

(6)其他的预热方式 除上述预热方式外,还可采用热水预热法、蒸气预热法、电预热法等多种方法进行低温启动。、

(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. ,

操作时,必须保证箱式变电站低压进线开关处于断开位置,机组油、水、合上预供油开关,启动电动预供油泵(或扳动手摇机油泵)。待主油道压力达100kPa启动要求值后,按下起动按钮“Start”,机组起动后,可按下“翻页"按钮,通过液晶显示屏检查发动机运行中各项技术参数的变化。起动成功后应怠速暖机,当机油温、水温达到40℃以上,方可加速、加载。按动或调节控制屏上加减速旋钮调整机组的频率,使之略高于额定频率。调整控制屏上的电压调节器的微调旋钮,使交流电压表在400V位置,按下“I/O”按钮,此时在站控室SCADA监控界面上“发电机”栏中可监控相关数据,机组便向负载供电。

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.
