一、机组启动的准备

I. Preparations for Unit Start-up
(1)检查流程是否畅通。
(1) Check whether the process is smooth.
(2)检查www.878365.com、发动机曲轴箱油位在规定范围以内,注油器油位不低于1/2刻度。
(2) Check the oil level of air compressor and engine crankcase within the prescribed range, and the oil level of injector is not less than 1/2 scale.
(3)检查膨胀水箱液位在1/2-2/3之间。
(3) Check the level of expansion tank between 1/2-2/3.
(4)检查润滑系统,并手动泵油30~50次,确认机组预润滑油泵正常。
(4) Check the lubrication system and manually pump the oil 30-50 times to confirm that the pre-lubrication oil pump of the unit is normal.
(5)检查机组洗涤罐、发动机润滑油加热器、压缩机油加热器处于关闭状态。
(5) Check that the washing tank, engine lubricating oil heater and compressor oil heater of the unit are closed.
(6)检查发动机、压缩机控制器上的紧急按钮全部处于运行状态,且无报警显示。
(6) Check that all the emergency buttons on the engine and compressor controller are in operation, and there is no alarm display.
(7)检查加载阀工作良好,确认各洗涤罐、分离器内无残液。
(7) Check that the loading valve works well, and confirm that there is no residual liquid in each washing tank and separator.
(8)用盘车工具转动飞轮,使压缩机曲轴旋转2~3周,检查机组有无摩擦,卡阻等异常现象。
(8) Rotate the flywheel with a turning tool to rotate the crankshaft of the compressor for 2-3 weeks. Check whether there are abnormal phenomena such as friction and obstruction in the unit.

二、机组启动
II. Unit Start-up
(1)将www.878365.com电源控制开关打到"AUTO”位置,给PLC供电。
(1) Put the power control switch of air compressor into the position of "AUTO" to supply power to PLC.
(2)按下复位按钮,测试有无故障报警信号。
(2) Press the reset button to test the fault alarm signal.
(3)调整气动马达单向轮与飞轮齿圈啮合。
(3) To adjust the meshing between the unidirectional wheel of pneumatic motor and the flywheel gear ring.
(4)开启预润滑油泵,进行机组预热润滑,待油温升至36℃以上且确认各部件预热正常。
(4) Open the pre-lubricating oil pump and preheat and lubricate the unit until the temperature of the oil rises above 36 and confirm that the parts are preheated normally.
(5)按下“启动”阀门手柄,待机组达到50rpⅡmin,缓慢开启燃气控制阀,迅速关闭气动阀,机组开启运行。
(5) Press the "start" valve handle and wait for the unit to reach 50rp II min. Slowly open the gas control valve, quickly close the pneumatic valve, and the unit opens and operates.
(6)当润滑油温大于36℃,冷却水温度大于50℃,并无异常现象后,准备加载。
(6) When the temperature of lubricating oil is higher than 36 C and the temperature of cooling water is higher than 50 C, there is no abnormal phenomenon, prepare to load.
三、机组加载
III. Unit Loading
(1)打开加载阀,慢开工艺气进气阀,待机组平稳后将迸气阀逐步打开,缓慢加载(控制进气压力从0. 55MPa~1.45MPa,平稳操作,确保机组缓慢安全平稳加载)。
(1) Open the loading valve, slowly open the process air intake valve, and gradually open the burst valve after the unit is stable, and slowly load (control the intake pressure from 0.55 MPa to 1.45 MPa, smooth operation to ensure the slow, safe and stable loading of the unit).
(2)加载完闭后,全面监控各部件运行情况正常,并调整至所需怠速。
(2) After loading and closing, the operation of each component is monitored and adjusted to the required idle speed.
七、停运
Seven, outage
(1)按“机组停机”按钮,www.878365.com将自行停机。
(1) Press the "unit shutdown" button, the air compressor will shut down by itself.
(2)若遇到紧急情况,可通过按下控制器上的“紧急按钮”停机。
(2) If there is an emergency, it can be stopped by pressing the "emergency button" on the controller.
(3)关闭工艺气进气阀,打开放空阀对机组进行泄压,泄压完毕后关放空阀门。
(3) Close the process air intake valve, open the vent valve to relieve the pressure of the unit, and close the vent valve after the pressure relief is completed.
(4)环境温度较低时,将所有伴热系统开启。
(4) When the ambient temperature is low, all tracing systems should be turned on.
