(一)开机前的预备

(1) Preparations before start-up

机组安装结束,按产品技能要求全面查看。承认各设备安装正确、线路无误、操作部分应灵敏、运动件不得有卡滞、元器材齐全牢靠后方可预备投入运转。

Unit installation is completed, according to product skill requirements for comprehensive inspection. Acknowledging that the equipment is installed correctly, the line is correct, the operation part should be sensitive, the moving parts should not be stuck, and the spare parts are complete and reliable before they can be ready for operation.

查看各联接紧固件应安装结实、操作部分应灵便。电缆接线不松动,蓄电池连接线正负极间隔间隔应大于150mm,避免相碰而发生火花。

Installation and operation of fasteners should be flexible. Cable wiring is not loose, and the gap between positive and negative poles of battery wiring should be greater than 150 mm to avoid sparks due to collision.

初度投入运转的机组,应测量各电器回路对地及回路之间的冷态绝缘电阻。可用500V兆欧表测量(此刻,天然气机电气部分半导体器材、电容器等弱电元件的连接线均应断开),测量成果不低于2MΩ。

For units initially put into operation, the cold insulation resistance of each electrical circuit to the ground and between the circuits should be measured. It can be measured by 500V megohm meter (at this moment, the connecting wires of semiconductor devices, capacitors and other weak electric components in the electrical part of natural gas machine should be disconnected), and the measurement results are not less than 2M.

并网或并联运转的机组,运转前应做相序测试,保证本机与它机或电网的相序相同。

Before operation, phase sequence test should be done to ensure that the phase sequence of the unit is the same as that of other machines or power grids.

所有电器开关及调理旋钮应位于相应停机位置。

All electrical switches and conditioning knobs shall be located at the corresponding stop position.

操控屏蓄电池及电子调速器电源开关置“通”位,按试报警按钮查看各报警指示灯及声音是否正常,假如发现指示灯不闪烁或无音响,应进行查看扫除或更换。查看结束按动消音及报警免除按钮,使各报警信号恢复。

Operating screen battery and electronic governor power switch is "on" position, press the test alarm button to check whether the alarm lights and sounds are normal. If it is found that the lights do not flicker or sound, it should be checked and swept or replaced. Press muffler and alarm exemption button at the end of viewing to restore the alarm signals.

天然气发动机开机前的预备请参阅天然气发动机运用保护说明书,查看润滑、冷却、气源、启动、操纵等系统的预备工作。发电机、操控屏也按照运用说明要求,做好开机前的预备。

For the preparation of natural gas engine before starting, please refer to the Protection Manual of natural gas engine, and check the preparation of lubrication, cooling, gas source, start-up and operation systems. Generators and control screens are also prepared before starting according to the requirements of operation instructions.

(二)开机操作

(2) Boot-up operation

开机操作能够在机旁进行,也能够在操控屏端进行。

Boot-up operation can be carried out at the side of the machine, but also at the control screen.

注意:操作过程中注意观察机组油、水、气等是否正常。

Note: During the operation, pay attention to observe whether the oil, water and gas of the unit are normal.

.手动操作

Manual operation

合上预供油开关,启动电动预供油泵(或扳动手摇机油泵)。待主油道压力到达100kPa后,按下起动按钮,机组起动后,立即开释起动按钮并断开起动开关。机组每次起动时刻为5s,若连续起动三次不成功,应查看原因,扫除故障后再起动。

Close the pre-supply switch and start the electric pre-supply pump (or pull the hand-cranked oil pump). When the main oil pressure reaches 100kPa, press the start button. After the unit starts, release the start button and disconnect the start switch immediately. The start-up time of the unit is 5 seconds each time. If three successive start-ups are unsuccessful, the cause should be checked and the fault should be cleared before starting.

发动机运转后,可按下翻页按钮,通过液晶显示屏查看发动机运转中各项技能参数的改变。起动成功后应怠速暖机,当机油温、水温到达40℃以上,方可加快、加载。

After the engine is running, the page-turning button can be pressed to check the changes of various technical parameters in the engine operation through the LCD screen. After successful start-up, idle warmer should be used. When oil temperature and water temperature reach above 40 C, it can be accelerated and loaded.

按动或调理操控屏上加减速旋钮调整机组的频率,使之略高于额外频率。调整操控屏上的电压调理器的微调旋钮,使沟通电压表在400V位置,合上主开关,机组便向负载供电。

Press or adjust the acceleration and deceleration knob on the control panel to adjust the frequency of the unit slightly higher than the additional frequency. Adjust the fine-tuning knob of the voltage regulator on the control panel, so that the communication voltmeter is at 400 V position, close the main switch, and the unit will supply power to the load.

机组带载运转后,若电压、频率偏离了额外值,别离调理转速旋钮和电压整定电位器,使电压频率到达额外值。

If the voltage and frequency of the unit deviate from the extra value after on-load operation, the adjusting speed knob and the voltage setting potentiometer are separated to make the voltage frequency reach the extra value.
