罗茨风机运行时对温度的要求

文章出处:罗茨风机厂家   发布时间:2020-04-24    点击数:   【
        罗茨风机最大的特点是使用时当压力在允许范围内加以调节时流量之变动甚微,压力选择范围很宽,具有强制输气的特点。输送时介质不含油。结构简单、维修方便、使用寿命长、整机振动小。真空泵。由于周期性的吸、排气和瞬时等容压缩造成气流速度和压力的脉动,因而会产生较大的气体动力噪声。此外,转子之间和转子与气缸之间的间隙会造成气体泄漏,从而使效率降低。罗茨风机的排气量为0.15~150立方米/分,转速为 150~3000转/分。单级压比通常小于1.7,最高可达2.1,可以多级串联使用。
The biggest characteristic of Roots blower is that when the pressure is adjusted within the allowable range, the flow changes little, the pressure selection range is very wide, and it has the characteristics of forced gas transmission. The medium does not contain oil during transportation. The utility model has the advantages of simple structure, convenient maintenance, long service life and small vibration of the whole machine. Vacuum pump. Because the periodic suction, exhaust and instantaneous constant volume compression cause the pulsation of air velocity and pressure, it will produce large aerodynamic noise. In addition, the gap between rotors and between rotors and cylinders will cause gas leakage, thus reducing efficiency. The exhaust volume of Roots blower is 0.15-150 m3 / min, and the rotating speed is 150-3000 rpm. The single-stage pressure ratio is usually less than 1.7, up to 2.1, which can be used in series.
        按转子的形状,罗茨风机分为两叶型和三叶型。三叶型转子每转动一次由两个转子进行三次吸、排气。与二叶型相比,气体脉动性小,振动也小,噪声低.
According to the shape of rotor, roots blower can be divided into two blade type and three blade type. Every time the three blade rotor rotates, two rotors conduct three times of suction and exhaust. Compared with the two blade type, the gas pulsation is small, the vibration is small and the noise is low
        夏季和冬季使用罗茨风机,对风机的检查密度要增大,原本一天检查1到2次,要增加到3到4次,一旦发生故障及时停机检查。水冷型罗茨风机,在冬季要注意:防止水冷管结冰或者冻裂,停机,要把水冷管里面的水清理干净。
When using roots blower in summer and winter, the inspection density of the blower should be increased. Originally, it should be inspected once or twice a day, and it should be increased to three or four times. In case of failure, the blower should be shut down for inspection in time. In winter, the water-cooled roots blower should pay attention to: prevent the water-cooled pipe from freezing or cracking, shut down, and clean up the water in the water-cooled pipe.
        在夏季,罗茨风机的进气温度一般要控制在40℃一下,超过这个温度,罗茨风机可能存在温度过高的情况,容易烧电机。有些地区气温低还可能与海拔因素有关,如果是海拔较高,温度较低,在罗茨风机选型时,要特别注意一下,不能按照平常情况进行选型,海拔对风量和压力都有影响。
In summer, the air inlet temperature of Roots blower is generally controlled below 40 ℃. If it exceeds this temperature, the temperature of Roots blower may be too high and it is easy to burn the motor. In some areas, the low temperature may also be related to the altitude factors. If the altitude is high and the temperature is low, special attention shall be paid to the selection of Roots fan. It cannot be selected according to the normal situation, and the altitude has an impact on the air volume and pressure.
        一般类型的罗茨风机主要放置在地面以上,环境温度的高低都会给罗茨风机造成影响,缩短使用寿命,所以最好建造一个风机房有效控制环境温度保护罗茨风机。
General types of roots fans are mainly placed above the ground. The ambient temperature will affect the roots fans and shorten their service life. Therefore, it is better to build a fan room to effectively control the ambient temperature and protect the roots fans.
        罗茨风机的使用要求是,输送的进气介质温度不得高于40℃,介质中的微粒杂质含量不得大于1000mg/m3,微粒的最大尺寸应在0,1mm以下。使用升压时,不得超过风机铭牌上所规定的额定升压值,由于罗茨风机结构特殊,因此在运转要求上同其它的风机有许多不同之处,必须注意。
The operating requirements of Roots blower are that the temperature of the conveying air inlet medium shall not be higher than 40 ℃, the content of particulate impurities in the medium shall not be greater than 1000mg / m3, and the maximum size of the particles shall be less than 0,1mm. When boosting is used, the rated boosting value specified on the nameplate of the fan shall not be exceeded. Due to the special structure of Roots fan, there are many differences with other fans in the operation requirements, which must be noted.
        当罗茨风机正常运转后,操作工应密切注视所有部件运行状况,随时观察机器各部件的温度,机器的振动,以及消声器的噪音,如有异常应立即停机。
After the roots blower operates normally, the operator shall pay close attention to the operation condition of all parts, observe the temperature of all parts of the machine, the vibration of the machine and the noise of the muffler at any time, and stop the machine immediately in case of any abnormality.
        罗茨风机的工作环境温度不得超过40摄氏度,如超过时要采取措施进行降温,否则缩短风机的使用寿命。风机室外配置时,请设置防雨棚。基础设计应符合国家机械设备安装工程的相关规定,基础应建在坚硬的土壤上,且高出地面100-250毫米,深度为800-1500毫米。基础承重面应比底座加宽100-250毫米,其基础不准与其他建筑及墙壁基础连接地基要牢固。风机周围要留有足够的空间,以满足检修和拆卸的需要。
The working environment temperature of Roots blower shall not exceed 40 ℃. If it exceeds 40 ℃, measures shall be taken to reduce the temperature, otherwise the service life of the blower will be shortened. When the fan is configured outdoors, please set up a rainproof shed. The foundation design shall comply with the relevant provisions of the national mechanical equipment installation engineering. The foundation shall be built on hard soil, 100-250mm above the ground, and 800-1500mm deep. The bearing surface of the foundation shall be 100-250mm wider than the base, and the foundation shall not be connected with other building and wall foundation firmly. Enough space shall be reserved around the fan to meet the needs of maintenance and disassembly.

        安装前清除管道内焊渣等异物,阀门要置于全开状态,否则风机超负荷运转,风机受损。检查,加注齿轮油。出厂时,油箱内可能未加注齿轮油,请检查加注齿轮油。在停机状态,加至油窗中央即可,加油过多将导致漏油。
Before installation, the welding slag and other foreign matters in the pipeline shall be removed, and the valve shall be placed in the fully open state, otherwise the fan will be overloaded and damaged. Check and add gear oil. When leaving the factory, the oil tank may not be filled with gear oil, please check the filling gear oil. In the shutdown state, add oil to the center of the oil window. Excessive oil filling will cause oil leakage.
        检查窄V带松紧和皮带轮偏正,皮带轮偏正可用直尺调正。当使用一段时间后皮带会变松,此时要重新调整。检查电源电压和频率是否符合铭牌标注要求。检查皮带轮转向,面对皮带轮观察,皮带轮转向要与旋转标志箭头相符。
Check the tightness of narrow V-belt and the deviation of pulley. The deviation of pulley can be adjusted with ruler. When the belt becomes loose after a period of use, readjust it. Check whether the power supply voltage and frequency meet the requirements of nameplate. Check the pulley steering, observe the pulley face to face, and the pulley steering shall be consistent with the rotation mark arrow.
罗茨风机在冬季也能够使用,并且在零下30摄氏度的环境中都可以使用,在冬季使用罗茨风机要更加注意,低温环境和高温环境对罗茨风机都会产生损坏。
Roots fans can also be used in winter, and can be used in the environment of - 30 ℃. Pay more attention to the use of roots fans in winter. Low temperature and high temperature environment will cause damage to roots fans.
        相信大家看完以上内容以后,应该也对罗茨风机运行时对温度的要求有所了解了,希望会对大家有所帮助吧。
I believe that after reading the above content, you should also understand the temperature requirements of Roots blower when it is running. I hope it will help you.
