为保证发电机组正常的运作和有长的使用期限，优良的维护保养是重要。那麼我们在维护保养前必须做那些提前准备呢？要认真地实行挤出机螺杆压缩机组的维护保养技术规范。在下手开展维护保养以前，最少搞好下述提前准备：
To ensure the normal operation and long service life of the generator set, excellent maintenance is important. So what preparations must we make in advance before maintenance and upkeep? We must conscientiously implement the technical specifications for maintenance and upkeep of the extruder screw compressor unit. Before starting maintenance, at least make the following preparations in advance:
1.一定要先断开机箱电源并在电源总开关处放上标示。
1. Be sure to first disconnect the chassis power and place a label at the main power switch.
2.关掉通往供气系统软件的截止阀门防止空气压缩逆流回被维修的一部分，一定不必借助本产品来防护供气系统软件。
2. Turn off the shut-off valve leading to the gas supply system software to prevent air compression from flowing back to the repaired part. It is not necessary to use this product to protect the gas supply system software.
3.开启手动式放空阀，排尽体系内的工作压力，维持放空阀处在打开情况。
3. Open the manual vent valve, exhaust the working pressure in the system, and maintain the vent valve in an open position.
4.针对水冷散热机器，务必关掉供水设备，释放出来自来水管路工作压力。
4. For water-cooled heat dissipation machines, be sure to turn off the water supply equipment and release the working pressure of the tap water pipeline.
5.保证压缩机组已制冷，避免烧伤.烧灼。
5. Ensure that the compressor unit has cooled down to avoid burns and burns.
6.擦干净路面油痕.水渍，避免摔倒。
6. Clean the oil and water stains on the road surface to avoid falling.
在修理时这四点一定要留意：
When repairing, these four points must be noted:
1.不必认为机器关机，就觉得需要开展维修，维护保养工作中，机器的全自动自动控制系统随时随地会运行压缩机。
1. There is no need to think that the machine is shut down, just because it needs to be repaired. During maintenance work, the fully automatic control system of the machine will run the compressor anytime and anywhere.
2.欠佳的维型槽模具 一次性止血带 保定水处理设备 一次性止血带 保定空压机 北京真空泵护保养不但会直接影响发电机组的常规运作，并且还有可能危害实际操作工作人员的安全性。
2. Poor maintenance not only directly affects the normal operation of the generator set, but also may endanger the safety of actual operating personnel.
3.在压缩机运作或带压时，不必拆装螺帽.给油塞及其其他零件。
3. When the compressor is operating or under pressure, it is not necessary to disassemble nuts, oil plugs, and other parts.
4.不能应用易燃性有机溶剂，如车用汽油或汽油清理空气过滤网或别的零部件。
4. Do not use flammable organic solvents, such as gasoline or gasoline for cleaning air filters or other components.
