天然气发电机组作为重要的能源转换设备，其稳定运行对于保障电力供应至关重要。为了确保机组的安全、高效运行，日常巡检是必不可少的工作环节。下面将详细介绍天然气发电机组日常巡检的项目及其重要性。

　　As an important energy conversion equipment, the stable operation of natural gas generators is crucial for ensuring power supply. In order to ensure the safe and efficient operation of the unit, daily inspections are an essential part of the work. The following will provide a detailed introduction to the daily inspection items and their importance for natural gas generator sets.

　　一、机组外观检查

　　1、 Appearance inspection of the unit

　　机组外观检查是日常巡检的第一步，也是最直观的检查环节。巡检人员需要仔细观察机组的外壳、管道、阀门等部件，检查是否有损坏、变形、泄漏等异常情况。同时，还要检查机组周围的清洁度，确保没有杂物堆积，以免影响机组的散热和正常运行。

　　The appearance inspection of the unit is the first step and the most intuitive inspection link in daily inspections. Inspection personnel need to carefully observe the casing, pipelines, valves, and other components of the unit to check for any abnormal conditions such as damage, deformation, or leakage. At the same time, it is necessary to check the cleanliness around the unit to ensure that there is no accumulation of debris, so as not to affect the heat dissipation and normal operation of the unit.

　　二、运行参数监测

　　2、 Monitoring of operational parameters

　　运行参数监测是日常巡检的核心内容之一。巡检人员需要定期记录机组的运行参数，如温度、压力、电流、电压等，并与正常范围进行对比。如果发现参数异常，需要及时采取措施进行处理，以免对机组造成损害。

　　Monitoring operational parameters is one of the core contents of daily inspections. Inspection personnel need to regularly record the operating parameters of the unit, such as temperature, pressure, current, voltage, etc., and compare them with the normal range. If abnormal parameters are found, measures should be taken in a timely manner to avoid damage to the unit.

　　温度监测：检查机组各部件的温度，如发动机缸体温度、排气温度等，确保其在正常范围内。

　　Temperature monitoring: Check the temperature of various components of the unit, such as engine cylinder temperature, exhaust temperature, etc., to ensure that they are within the normal range.

　　压力监测：检查天然气进气压力、润滑油压力等，确保机组在稳定的压力下运行。

　　Pressure monitoring: Check the natural gas intake pressure, lubricating oil pressure, etc. to ensure that the unit operates at a stable pressure.

　　电流电压监测：检查发电机的输出电流和电压，确保其稳定且符合负载要求。

　　Current and voltage monitoring: Check the output current and voltage of the generator to ensure stability and compliance with load requirements.

　　三、润滑系统检查

　　3、 Lubrication system inspection

　　润滑系统是保障机组正常运行的关键部件之一。巡检人员需要检查润滑油位是否正常，油质是否清洁，以及润滑系统是否有泄漏现象。如果发现润滑油位过低或油质变差，需要及时添加或更换润滑油，以确保机组的良好润滑。

　　The lubrication system is one of the key components to ensure the normal operation of the unit. The inspection personnel need to check whether the lubricating oil level is normal, whether the oil quality is clean, and whether there is any leakage in the lubrication system. If the lubricating oil level is found to be too low or the oil quality deteriorates, it is necessary to add or replace the lubricating oil in a timely manner to ensure good lubrication of the unit.

　　四、冷却系统检查

　　4、 Cooling system inspection

　　冷却系统对于维持机组正常运行温度至关重要。巡检人员需要检查冷却液位是否正常，冷却系统是否有泄漏现象，以及冷却风扇是否运转正常。如果发现冷却液位过低或冷却系统有泄漏，需要及时补充冷却液或修复泄漏点，以确保机组的正常散热。

　　The cooling system is crucial for maintaining the normal operating temperature of the unit. The inspection personnel need to check whether the coolant level is normal, whether there is any leakage in the cooling system, and whether the cooling fan is running normally. If the coolant level is found to be too low or there is a leak in the cooling system, it is necessary to replenish the coolant or repair the leak point in a timely manner to ensure the normal heat dissipation of the unit.

　　五、电气系统检查

　　5、 Electrical system inspection

　　电气系统是机组的重要组成部分，其稳定性直接影响到机组的运行安全。巡检人员需要检查电缆连接是否牢固，绝缘性能是否良好，以及电气元件是否有异常发热或损坏现象。如果发现电缆连接松动或绝缘性能下降，需要及时进行处理，以确保电气系统的稳定运行。

　　The electrical system is an important component of the unit, and its stability directly affects the safe operation of the unit. The inspection personnel need to check whether the cable connection is firm, whether the insulation performance is good, and whether there is abnormal heating or damage to the electrical components. If loose cable connections or decreased insulation performance are found, timely handling is necessary to ensure the stable operation of the electrical system.

　　六、安全装置检查

　　6、 Safety device inspection

　　安全装置是保障机组安全运行的重要防线。巡检人员需要检查机组的安全装置，如紧急停机按钮、超速保护装置、燃气泄漏报警装置等，确保其处于良好状态。如果发现安全装置失效或异常，需要及时进行修复或更换，以确保机组在紧急情况下能够迅速停机，避免事故的发生。

　　The safety device is an important defense line to ensure the safe operation of the unit. Inspection personnel need to check the safety devices of the unit, such as emergency stop buttons, overspeed protection devices, gas leak alarm devices, etc., to ensure that they are in good condition. If safety devices are found to be malfunctioning or abnormal, they need to be repaired or replaced in a timely manner to ensure that the unit can be quickly shut down in emergency situations and avoid accidents.

　　七、巡检周期与记录

　　7、 Inspection cycle and records

　　日常巡检需要按照一定的周期进行，以确保机组始终处于良好的运行状态。巡检人员需要根据机组的运行情况和维护手册的要求，制定合理的巡检周期，并认真记录每次巡检的结果。通过记录巡检结果，可以追踪机组的状态变化，及时发现潜在问题，并采取相应的措施进行处理。

　　Daily inspections need to be conducted at regular intervals to ensure that the unit is always in good operating condition. Inspection personnel need to develop a reasonable inspection cycle based on the operation of the unit and the requirements of the maintenance manual, and carefully record the results of each inspection. By recording the inspection results, the status changes of the unit can be tracked, potential problems can be discovered in a timely manner, and corresponding measures can be taken to deal with them.

　　八、巡检人员的专业要求

　　8、 Professional requirements for inspection personnel

　　日常巡检工作需要由具备一定专业知识和技能的人员来进行。巡检人员需要熟悉机组的运行原理、结构特点和维护要求，能够准确判断机组的运行状态，并及时发现和处理异常情况。同时，巡检人员还需要具备良好的责任心和安全意识，确保巡检工作的有效性和安全性。

　　Daily inspection work needs to be carried out by personnel with certain professional knowledge and skills. Inspection personnel need to be familiar with the operating principles, structural characteristics, and maintenance requirements of the unit, be able to accurately judge the operating status of the unit, and promptly detect and handle abnormal situations. At the same time, inspection personnel also need to have a good sense of responsibility and safety awareness to ensure the effectiveness and safety of inspection work.
