罗茨鼓风机日常保养常识

　　一、定期更换罗茨风机油液

　　罗茨鼓风机是生产企业常用的设备，这涉及到了三叶罗茨鼓风机的保养问题。如果保养得当，会大大延长使用寿命以及运行的稳定性。润滑油经过一段时间的使用，会发生性能老化和泄露消耗，因此需要及时进行补充或更换，我整理了一下换油和保养的方法。

　　罗茨鼓风机*基础的保养就是换油，一般罗茨风机累计运行1000小时后就要进行换油。采用220#齿轮油进行更换，油位应在油镜的一半，切忌过高或过低。

　　另要注意的是，换油的时候要将油箱里的油先排空后再注入新油。不要在旧油的基础上添加，这样时间长了会导致油箱的油太脏、太稠。从而影响罗茨鼓风机的运作。

　　除了油位需要日常检查注意外，皮带松紧度、空气滤芯的检查也同样重要。每半月对滤芯进行彻底清扫根据使用情况，至少每半年更换一次滤芯 。罗茨鼓风机的所有部位，哪怕再小，也是至关重要的。切不可因为偷懒忽视，而因小失大。

　　罗茨鼓风机各机型的油量随时都可以看到齿轮侧油镜，停机时可以在中线之间保持油面。机油水平低于中间位置时，应及时添加润滑油。如果油位高于中间位置，则有可能发生油温高、尾气喷射、气体漏油等。

　　轴承润滑脂要用指定的润滑耐热油脂(通用锂基润滑脂ZL-3/二硫化钼)，累计运行150小时加一次(3个月内不足150小时也必须用黄油枪打入)，加注时必须保证黄油确实已经加入。

　　加注方法：用油脂枪加油脂到规定量。(添加油脂要在刚停机后进行)补充油脂到完毕后运行15分钟，确认多余的油脂从风机端盖的放油槽中流出。停机后擦掉多余的油脂。

　　一般的罗茨风机的使用条件有以下几点：

　　1.进口气体温度不大于35℃ 。

　　2.气体中固体微粒含量不大于100m3，微尘**颗粒尺寸应不大于0.05毫米。

　　3.煤气的含煤焦油指标应符合TJ28-78城市煤气规范设计的规定 。

　　4.轴承温度**不超过85℃ 。

　　5.润滑油温度**不超过65℃ 。

　　6.风机上的所示压力不得超过标牌所规定的升压范围，否则必须停车检查系统中进口是否堵塞，进排气口阀门是否全部关闭，风机中的静动件是否发生摩擦等其他一些问题，并采取相应措施。

　　二、检查罗茨鼓风机固定螺栓

　　1.检查各部位的紧固情况及定位销是否有松动现象;

　　2.罗茨鼓风机机体内部是否有漏水、漏油现象;

　　3.罗茨鼓风机机体内部不能有结构、生锈和剥落现象存在;

　　4.罗茨鼓风机拆卸机器前，应对机器各配合尺寸进行测量，作好记录，并在零部件上作好标记，以保证装配后保持原来配合要求;

　　5.罗茨鼓风机的轴承与齿轮采用飞溅润滑，须保证润滑油与上述润滑油性能相当以利于齿轮与轴承正常运行，油箱中的油量在停车时要保证在油标中线以上，润滑油要定期更换，**次启动工作200小时、换**次油，以后每半年换油。注入新油前应用中性煤油把油箱和齿轮清洗干净;

　　6.注意润滑及冷却情况是否正常，注意润滑的质量。经常倾听罗茨鼓风机运行有无杂声。注意机组是否在不符合规定的工况下运行;

　　7.罗茨鼓风机的过载，有时不是立即显示出来的，所以要注意进、排气压力，轴承温度和电动机电流的增加趋势，籍以判断机器是否运行正

　　8.维护检修应按具体使用情况拟定合理的维修制度，按期进行，并作好记录，建议每年大修一次，并更换轴承和有关易损件。

　　罗茨鼓风机维护保养对风机长时间正常运转至关重要，我们在日常保养罗茨鼓风机过程中应注意风机润滑及冷却情况是否正常，注意润滑的质量，经常倾听递罗茨鼓风机运转过程中，有无异常情况、异常振动以及异常响动，及时根据异常针对性检修维护。

　　三、开机关机注意事项

　　1.由于风机出口不畅通，风不通，压力增加，电动机形成过载浪涌，管道被阻塞，然后设备的电流表增加。电流过载的不正确操作也会在操作期间引起问题。例如，如果设备倒转，则阀门未完全打开，此操作可能导致发动机立即燃烧。

　　2.在操作中，必须按照规定进行操作，禁止引起不必要的问题。润滑油如果缺少设备润滑油，风机将继续无油运行。叶轮将发生碰撞，齿轮将磨损，然后增加电动机的负载。它只会增加发动机的负载，从而加速损失。涡轮本身的问题是工厂中存在质量问题。安装风机时，许多组件组合不良，将导致分类冲突。

　　3.根据罗茨鼓风机故障分析的准备，罗茨鼓风机制造商的零件维护和更换规则，确定维修地点和规模，并准备可能需要更换的零件。根据零件的结构准备适当的检查元件和测量工具。根据罗茨鼓风机的质量，制定了审查计划。

　　4.实施安全措施。删除预防措施时，必须标记重要部件的尺寸和设备的方向，以便在组装过程中恢复检查标记，以免卡住。例如，测量并记录几个楔块的厚度，测量并记录转子各个部分的间隙，并对主齿轮和从动件以及喉咙中的相应符号进行汇总。

　　5.在安装罗茨鼓风机之前，清洁并查看将要使用的零件。对于已拆卸的零件，必须保护加工外观并按照某些规则进行放置。同一零件必须放置在一起，例如外壳，填料函和同一零件的调节垫圈。缺少的零件必须包含在专用设备中。匹配的应用程序必须存储在一起。

　　四、总结

　　罗茨风机保养的常识和方法是：

　　1、开机前请一定要先打开手动放空阀，检查油箱机油是否已到油位线，用手盘动风机是否灵活，如果盘动灵活，再按启动，然后慢慢将放空阀关闭，使三叶罗茨鼓风机达到满负荷(切记不能超载运行)。关机时请一定先打开放空阀，然后再按断开。这样正常操作使用才能延锦工机使用寿命。

　　2、请定时定期派人检查风机油箱油位如发现机油低于油标中间位置，即请马上补充。如发现油标和放油塞还有油箱结合处有漏油迹象则必须及时更换修复。请每半年完全更换一次机油。油标很脏无法看清机油时则需马上把油标清洗干净，以防误导油箱机油油位而烧坏齿轮，如机油明显很脏时也应及时更换。

　　3、如果轴承是使用油脂润滑的，则每三个月至半年必须补充一次，每年必须更换一次风机高温油脂。(注：三叶罗茨鼓风机均使用纯正的二硫化钼3号锂基脂或风机专用高温润滑脂。)风机运行时须检查油箱温度、振动及声音，检查进排气压力电流表指数等是否正常。

　　4、请确保风机房空气流通顺畅、降温措施完备，注意风机房的清洁工作，以免由于风机吸入灰尘太多而堵塞进气过滤消声器或卡死风机。则必须定期清洗过滤器内的滤芯(海绵或过滤无防材料)和进气消声器内的灰垢，无法清洗或清洗不干净时请及时更换空气过滤器滤芯。

　　5、请定期检查、调整皮带张力，进行一次小保养，内容包括检查风机轴承，齿轮是否磨损过度或者前期损坏;清洗风机油箱、气腔、密封装置;校正风机各部位间隙;及时发现和解决产生的问题，以避免造成风机更严重的损伤。

　　Common sense of daily maintenance of Roots blower

　　1、 Change the oil of Roots blower regularly

　　Roots blower is a common equipment in production enterprises, which involves the maintenance of three leaf roots blower. If properly maintained, the service life and operation stability will be greatly extended. After a period of use, the lubricating oil will have performance aging and leakage consumption, so it needs to be supplemented or replaced in time. I sorted out the methods of oil change and maintenance.

　　The most basic maintenance of Roots blower is to change the oil. Generally, the oil should be changed after the roots blower has operated for 1000 hours. Use 220 # gear oil for replacement, and the oil level should be half of the oil mirror. Do not be too high or too low.

　　It should also be noted that when changing the oil, drain the oil in the oil tank first and then inject new oil. Don't add it on the basis of old oil, as the oil in the tank will be too dirty and thick after a long time. Thus affecting the operation of Roots blower.

　　In addition to the daily inspection of oil level, the inspection of belt tightness and air filter element is also important. Thoroughly clean the filter element every half a month, and replace the filter element at least every half a year according to the service condition. All parts of Roots blower, no matter how small, are also crucial. We must not lose much because of laziness and neglect.

　　The oil quantity of each model of Roots blower can be seen at any time from the oil mirror on the gear side, and the oil level can be maintained between the center lines when the blower is stopped. When the oil level is lower than the middle position, add lubricating oil in time. If the oil level is higher than the middle position, high oil temperature, tail gas injection, gas leakage, etc. may occur.

　　The bearing grease shall be lubricated with the specified lubricating heat-resistant grease (general lithium grease zl-3/ molybdenum disulfide), and it shall be added once after 150 hours of cumulative operation (it must also be injected with a grease gun if it is less than 150 hours within 3 months). When filling, it must be ensured that the grease has indeed been added.

　　Filling method: add grease to the specified amount with a grease gun. (adding grease should be carried out just after the shutdown) run for 15 minutes after adding grease, and confirm that the excess grease flows out of the oil drain tank of the fan end cover. Wipe off excess grease after shutdown.

　　The general operating conditions of Roots blower are as follows:

　　1. The inlet gas temperature shall not be greater than 35 ℃.

　　2. The content of solid particles in the gas shall not be greater than 100m3, and the maximum particle size of micro dust shall not be greater than 0.05 mm.

　　3. The coal tar index of the gas shall comply with the provisions of tj28-78 urban gas specification design.

　　4. The maximum bearing temperature shall not exceed 85 ℃.

　　5. The maximum temperature of lubricating oil shall not exceed 65 ℃.

　　6. The pressure indicated on the fan shall not exceed the pressure rise range specified on the label, otherwise it must stop to check whether the inlet of the system is blocked, whether all the inlet and outlet valves are closed, and whether the static parts in the fan have friction and other problems, and take corresponding measures.

　　2、 Check the fixing bolts of Roots blower

　　1. Check the fastening of each part and whether the locating pin is loose;

　　2. Whether there is water leakage and oil leakage inside the roots blower body;

　　3. There shall be no structure, rust and peeling inside the roots blower body;

　　4. Before disassembling the machine, the roots blower shall measure the matching dimensions of the machine, make records, and mark the parts to ensure that the original matching requirements are maintained after assembly;

　　5. The bearings and gears of Roots blower adopt splash lubrication. It is necessary to ensure that the performance of the lubricating oil is equivalent to that of the above lubricating oil, so as to facilitate the normal operation of the gears and bearings. The oil volume in the oil tank should be above the centerline of the oil standard when stopping. The lubricating oil should be changed regularly. The oil should be changed for the first time after the first start-up for 200 hours, and then every half a year. Clean the oil tank and gear with neutral kerosene before injecting new oil;

　　6. Pay attention to whether the lubrication and cooling conditions are normal, and pay attention to the quality of lubrication. Always listen to the roots blower for noise. Pay attention to whether the unit operates under conditions that do not meet the regulations;

　　7. The overload of Roots blower is sometimes not immediately displayed, so pay attention to the increasing trend of inlet and exhaust pressure, bearing temperature and motor current, so as to judge whether the machine is running correctly

　　8. A reasonable maintenance system shall be formulated according to the specific use conditions for maintenance and overhaul, which shall be carried out on schedule and recorded. It is recommended to overhaul once a year and replace the bearings and relevant vulnerable parts.

　　Routine maintenance site of Roots blower

　　The maintenance of Roots blower is very important for the normal operation of the blower for a long time. In the process of daily maintenance of Roots blower, we should pay attention to whether the lubrication and cooling of the blower are normal, pay attention to the quality of lubrication, often listen to whether there are abnormal conditions, abnormal vibration and abnormal sound during the operation of Roots blower, and timely repair and maintain according to the abnormalities.

　　3、 Precautions for startup and shutdown

　　1. Because the fan outlet is blocked, the wind is blocked, the pressure increases, the motor forms overload surge, the pipeline is blocked, and then the ammeter of the equipment increases. Incorrect operation of current overload can also cause problems during operation. For example, if the equipment is reversed and the valve is not fully opened, this operation may cause the engine to burn immediately.

　　2. During the operation, the operation must be carried out in accordance with the regulations, and unnecessary problems are prohibited. If there is a lack of equipment lubricating oil, the fan will continue to run without oil. The impeller will collide, the gear will wear, and then increase the load of the motor. It will only increase the load on the engine, thereby accelerating the loss. The problem of the turbine itself is the quality problem in the factory. When installing the fan, many components are poorly combined, which will lead to classification conflict.

　　3. According to the preparation of Roots blower fault analysis, the parts maintenance and replacement rules of Roots blower manufacturer, determine the maintenance location and scale, and prepare the parts that may need to be replaced. Prepare appropriate inspection elements and measuring tools according to the structure of the parts. According to the quality of Roots blower, the review plan is formulated.

　　4. Implement safety measures. When deleting preventive measures, the size of important parts and the direction of the equipment must be marked, so that the inspection mark can be restored during the assembly process to avoid jamming. For example, measure and record the thickness of several wedges, measure and record the clearance of each part of the rotor, and summarize the corresponding symbols in the main gear, follower and throat.

　　5. Before installing roots blower, clean and check the parts to be used. For disassembled parts, the machining appearance must be protected and placed according to certain rules. The same parts must be placed together, such as housing, stuffing box and adjusting washer of the same part. The missing parts must be included in the special equipment. Matching applications must be stored together.

　　4、 Summary

　　Common sense and methods of Roots blower maintenance are:

　　1. Before starting the machine, be sure to open the manual vent valve first, check whether the oil in the oil tank has reached the oil level line, and check whether the fan is flexible by hand. If it is flexible, press start, and then slowly close the vent valve to make the three leaf roots blower reach full load (remember not to overload operation). Please be sure to open the vent valve first and then press to disconnect when shutting down. In this way, the service life of Jingong machine can be extended after normal operation.

　　2. Please send someone regularly to check the oil level of the fan oil tank. If the oil level is lower than the middle position of the oil scale, please replenish it immediately. If there is any sign of oil leakage at the junction of the oil pointer, the oil drain plug and the oil tank, it must be replaced and repaired in time. Please change the oil completely every six months. If the oil mark is dirty and the oil cannot be seen clearly, the oil mark should be cleaned immediately to prevent misleading the oil level of the oil tank and burning the gear. If the oil is obviously dirty, it should also be replaced in time.

　　3. If the bearing is lubricated with grease, it must be supplemented every three months to half a year, and the high-temperature grease of the fan must be replaced once a year. (Note: all three leaf roots blowers use pure molybdenum disulfide No. 3 lithium grease or special high-temperature lubricating grease for fans.) When the fan is running, check the temperature, vibration and sound of the oil tank, and check whether the inlet and exhaust pressure, ammeter index, etc. are normal.

　　4. Please ensure that the air circulation in the fan room is smooth and the cooling measures are complete. Pay attention to the cleaning of the fan room to avoid blocking the intake filter silencer or blocking the fan due to too much dust inhaled by the fan. The filter element (sponge or filter without anti-corrosion material) in the filter and the ash dirt in the intake muffler must be cleaned regularly. If it cannot be cleaned or cannot be cleaned, please replace the air filter element in time.

　　5. Please check and adjust the belt tension regularly and carry out a small maintenance, including checking whether the fan bearings and gears are excessively worn or damaged in the early stage; Clean the oil tank, air chamber and sealing device of the fan; Correct the clearance of each part of the fan; Find and solve the problems in time to avoid more serious damage to the fan.
