螺杆鼓风机日常运行维护知识

随着螺杆鼓风机需求量日益提升，已广泛应用到水处理、冶炼高炉、洗煤厂、矿山浮选、化工造气、真空等领域，主要是因为鼓风机外形美观，稳定性好，维护方便。

With the increasing demand of screw blower, it has been widely used in water treatment, smelting blast furnace, coal washing plant, mine flotation, chemical gasification, vacuum and other fields, mainly because of its beautiful appearance, good stability and convenient maintenance.

（1）鼓风机运行时，应定期检查鼓风机进、排气的压力与温度，冷却用水或油的液体、压力与温度、空气过滤器的压差等。做好日常读表记¼，并进行分析对比。

(1) During the operation of the blower, the pressure and temperature of the inlet and outlet of the blower, the liquid, pressure and temperature of the cooling water or oil, and the pressure difference of the air filter should be checked regularly. Do a good job in daily reading and recording, and make analysis and comparison.

（2）定期清洗检查空气过滤器，保持其正常工作。

(2) Clean and check the air filter regularly to keep it working normally.

（3）注意进气温度对鼓风机（离心式）运行工况的影响，如排气容积流量、运行负荷与功率、喘振的可能性等，及时调整进口导叶或蝶阀的节流装置，克服进气温度变化对容积流量与运行负荷的影响，使鼓风机安 全稳定运行。

(3) Pay attention to the influence of intake air temperature on the operation condition of blower (centrifugal type), such as exhaust volume flow, operation load and power, possibility of surge, etc. timely adjust the throttle device of inlet guide vane or butterfly valve to overcome the influence of intake air temperature change on volume flow and operation load, so as to ensure the safe and stable operation of blower.

（4）经常注意并定期测听机组运行的声音和轴承的振动，即采取措施，必要时应停车检查，找出原因后，排除故障。

(4) Pay attention to and regularly listen to the running sound of the unit and the vibration of the bearing, that is, take measures, stop the machine for inspection if necessary, and remove the fault after finding out the cause.

（5）严禁离心鼓风机机组在喘振区运行。

(5) It is strictly forbidden for centrifugal blower unit to operate in surge zone.

（6）按说明书的要求，做好电动机或齿轮箱的检查和维护。

(6) Check and maintain the motor or gearbox according to the instruction.

（7）首次开机后200h应换油。如果被更换的油δ变质，经过滤机过滤后仍可重新使用。首次开机后500h作油样分析，以后ÿ月抽一次油样分析，发现油变质应即时换油。油号必须符合规定，严禁使用其他牌号的油。

(7) The oil should be changed 200 hours after the first startup. If the replaced oil δ deteriorates, it can still be reused after being filtered by the filter. The oil samples were analyzed 500 hours after the first start-up. After that, the oil samples were taken once a month. If the oil was found to be deteriorated, the oil should be changed immediately. The oil grade must meet the requirements. It is strictly forbidden to use other grades of oil.

（8）检查油箱中的油λ，不得低于最低油λ线，看油压是否保持正常值。经常检查轴承出口处的油温，不应超过50℃，并根据情况调节油冷却器的冷却水量，使进水轴承前的油温保持在30～40℃之间。

(8) Check the oil λ in the oil tank, which shall not be lower than the minimum oil λ line, to see if the oil pressure remains normal. Always check the oil temperature at the outlet of the bearing, which should not exceed 50 ℃, and adjust the cooling water volume of the oil cooler according to the situation, so that the oil temperature before the inlet bearing is kept between 30 ℃ and 40 ℃.

（9）定期清洗滤油器。经常检查空气过滤器的阻力变化，定期进行清洗和维护，使其保持正常工作。

(9) Clean the oil filter regularly. Check the resistance change of air filter regularly, clean and maintain it regularly to keep it working normally.

综上所述，一台好的螺杆鼓风机必得配备一个好的使用者，这个人需对鼓风机日常运行维护知识有个充分的了解，只有知识雄厚，维护经验十足的人，才能使得鼓风机使用寿命延长，工作效率才能提高。

To sum up, a good screw blower must be equipped with a good user. This person needs to have a full understanding of the daily operation and maintenance knowledge of the blower. Only those with strong knowledge and full maintenance experience can prolong the service life of the blower and improve the work efficiency.
