瓦斯发电机组的低温启动方式的使用步骤

来源:http://www.huannengpower.com   发布于:2019-07-19

1、选用低温性能好的瓦斯发电机组,低温黏度小,各摩擦副间光滑好,启动阻力小,利于启动。目前运用的多级油,如15W/40W前的数字越小则机油的低温活动性越好。因而,低温时引荐运用10W或5W机油。

1. Choose gas generator set with good low temperature performance, low low temperature viscosity, smooth friction pairs, small starting resistance, which is conducive to start-up. At present, the lower the number before 15W/40W, the better the low temperature activity of the multi-stage oil. Therefore, it is recommended to use 10W or 5W oil at low temperature.

2、采用低温性能好的蓄电池必要时可对蓄电池停止保温,以保证其低温条件下能正常充电且有足够的输出电流,从而进步了启动系统功率。

2. If it is necessary to use batteries with good cryogenic performance, the thermal insulation of the batteries can be stopped, so as to ensure that the batteries can be charged normally at low temperature and have enough output current, thus improving the power of the startup system.

3、加注冷起动液。

3. Add cold starter fluid.

4、火焰预热启动。

4. Flame preheating start.

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 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、电预热法等多种办法停止低温启动。

6. In addition to the above-mentioned preheating methods, other preheating methods can also use hot water preheating, steam preheating, electric preheating and other methods to stop low-temperature start-up.

操作时,必需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(或扳入手摇机油泵)。待主油道压力达100kPa启动请求值后,按下起动按钮“Start”,机组起动后,可按下“翻页"按钮,经过液晶显现屏检查发起机运转中各项技术参数的变化。起动胜利后应怠速暖机,当机油温、水温到达40℃以上,方可加速、加载。按动或调理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理器的微调旋钮,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 inlet switch of box substation is in the open position, the oil, water and pre-oil supply switch of the unit are closed, and the electric pre-oil supply pump (or the hand-cranked oil pump) is started. When the main oil pressure reaches 100kPa start-up request value, press the start button "Start", after the unit starts, press the "turn-over" button, and check the changes of technical parameters in the operation of the engine through the LCD display screen. After successful start-up, idle warmer should be used to accelerate and load when oil temperature and water temperature reach above 40 C. Press the acceleration and deceleration knob on the control panel to adjust the frequency of the unit so that it is slightly higher than the rated frequency. Adjust the fine-tuning knob of the voltage regulator on the control panel so that the AC voltmeter is at 400 V position and press the "I/O" button. At this time, relevant data can be monitored in the "Generator" column of the SCADA monitoring interface in the station control room, so that the unit can supply power to the load.
