空压机润滑油是否变质的简易鉴别方法

一、山东空压机开机前的准备工作

1、 Preparatory work before starting up Shandong air compressor

（1） 检查空压机各机械零部件和管道是否联接可靠，如有松动现象，及时处理。

(1) Check whether the mechanical parts and pipes of the air compressor are connected reliably. If there is looseness, handle it in time.

（2） 检查空压机油位高度，机组在停机时的油位高于油表上的位置时，机组即可正常开机运行，即便机组运行起来后，油位一下子看

(2) Check the oil level of the air compressor. When the oil level of the unit is higher than the lowest position on the oil gauge, the unit can be started and operated normally. Even after the unit is running, the oil level can be seen at once

不到也并不影响机组的正常使用。

If not, it will not affect the normal use of the unit.

(3) 用手按规定方向转动联轴器数转，确保机组转动灵活。

(3) Rotate the coupling by hand according to the specified direction to ensure the flexible rotation of the unit.

(4) 检查电气是否符合规程的要求，确认后接通机组电源。

(4) Check whether the electrical system meets the requirements of safety regulations, and turn on the power supply of the unit after confirmation.

二、螺杆空压机的启动

2、 Start up of screw air compressor

（1）空压机在初开车或空压机及其系统设备检修后重新起动时应遵循下述程序：

(1) The following procedures shall be followed during the initial start-up of the air compressor or restart after the maintenance of the air compressor and its system equipment:

a) 检查所有的阀是否均处于合适的位置及正确的启闭状态；

a) Check whether all valves are in proper position and open and close state correctly;

b) 除去所有为维护而安装的维修附件（如盲板）及维修用标志牌；

b) Remove all repair accessories (such as blind plates) and maintenance signboards installed for safety maintenance;

c) 检查系统并除去其内的外来异物；

c) Check the system and remove foreign matters in it;

d) 打开并再次关闭排污阀；

d) Open and close the drain valve again;

e) 盘车少一圈以确保无机械干涉；

e) Turn at least one turn to ensure no mechanical interference;

(2) 如机组在送电后，机组控制屏没有显示相序错误，则可按下“启动”按钮，正常开机，开机后请再次确认驱动电机以及旋转设备的旋

(2) If no phase sequence error is displayed on the control panel of the unit after power transmission, press the "start" button to start the machine normally. After starting up, please confirm the rotation of the driving motor and rotating equipment again

转方向正确，并确定所有的保护装置均处于合适的操作状态

Turn in the right direction and make sure all safety devices are in proper operation

螺杆压缩机主机在任何情况下都严禁反转！下列情况必须先确认主机转向：

Screw compressor host in any case are strictly prohibited to reverse! The steering direction of the main engine must be confirmed in the following situations:

1）新机开机调试;2）电源线重新接线；3）总电源换相

1) New machine start-up debugging; 2) rewiring of power line; 3) commutation of main power supply

对于因忽视这些警告和注意事项而导致的任何损坏或伤害，制造商概不承担任何责任

The manufacturer shall not be liable for any damage or injury caused by ignoring these warnings and precautions

4） 机组启动过程完成后空压机即进入自动控制状态。

4) After the start-up process of the unit is completed, the air compressor will enter the automatic control state.

三、螺杆空压机的运行

3、 Operation of screw air compressor

1） 机组正常运转后，检查一下机组内各处有无漏油漏气现象，如有则立即停车处理。

1) After the normal operation of the unit, check whether there is oil leakage and air leakage in the unit. If so, stop the machine immediately.

2） 检查排气压力，排气温度等运行参数是否正常。

2) Check whether the exhaust pressure, exhaust temperature and other operating parameters are normal.

3） 做好工作运行记录，比较各运行参数是否始终正常，如有反常现象应及时停机并分析查找原因。

3) Make a good record of the work and operation, compare whether the operation parameters are always normal. If there is abnormal phenomenon, stop the machine in time and analyze the causes.

四、空压机的停机

4、 Shutdown of air compressor

3.4.1  如需要停止运行机组，则只需按下停车按钮后，压缩机自动卸载约20-30秒后停车。没有特别原因，不要用急停按钮停机

3.4.1 if it is necessary to stop the unit, just press the stop button and the compressor will automatically unload for about 20-30 seconds and then stop. Do not use the emergency stop button to stop the machine without special reasons

3.4.2 切断机组电源

3.4.2 cut off the power supply of the unit

五、日常维护方便

5、 Convenient daily maintenance

1、压缩机应便于安装

1. The compressor shall be easy to install

从安装的方便性来考虑，现在市场上有移动式、便携式、免安装的空压机，所选的压缩机在满足用气的前提下体积要小，重量要轻，便于安

Considering the convenience of installation, there are mobile, portable and installation free air compressors on the market. The selected compressor should be small in volume, light in weight and easy to install on the premise of meeting the requirements of gas consumption

装。对用气场地狭小(船用、车用)的用气单元，应选立式压缩机;用气场合有长距离变化(超过500米)的用气单元，则应考虑移动式压缩机。

Install. Vertical compressor should be selected for gas consumption unit with narrow gas consumption site (Marine and vehicle); mobile compressor should be considered for gas consumption unit with long distance change (more than 500m).

2、压缩机的后期维护方便、成本低

2. The later maintenance of compressor is convenient and low cost

选择压缩机时要充分考虑到压缩机日常维护的便利性及维护成本。尽量选用易损件(主要是机油与滤芯)更换周期长、通用性强、售后服务期

The convenience and cost of routine maintenance of compressor should be fully considered when selecting compressor. Wear parts (mainly engine oil and filter element) shall be selected as far as possible with long replacement cycle, strong versatility and after-sales service period

长的压缩机。

Long compressor.

六，对空压机的其它要求

6、 Other requirements for air compressor

噪 音和振动对操作人员的身心以及车间、工厂的环境都有很大的影响，如果车间里总是很高分贝的噪音，生产现场的工人会产生烦躁感，必

Noise and vibration have a great impact on the physical and mental health of the operators and the environment of the workshop and the factory. If the noise in the workshop is always very high, the workers on the production site will have a sense of irritability

定影响生产效率和质量。而 且，局对生产噪音有一个控制上限，选择的压缩机噪音过大不符合标准。如果使用方购买的压缩机

It will affect the production efficiency and quality. Moreover, the National Environmental Protection Bureau has a control upper limit on the production noise, and the selected compressor is too noisy to meet the environmental protection standards. If the compressor purchased by the user

准备摆放在生产现场，应尽量选择噪音指数低、具有 良好抗振性能的压缩机。

The compressor with low noise index and good anti vibration performance should be selected as far as possible when it is ready to be placed on the production site.
