罗茨鼓风机是一种定容积回转式气体动力机械。气缸由机壳和两端墙板包容而成，一对相互“咬合”（因为有间隙，两叶轮并不直接接触）的叶轮将进气口与排气口分隔开来，通过一对同步齿轮的转动，两叶轮在气缸中作等速反方向旋转，在旋转过程中，进气口的气体不断的被叶轮推移到排气口，从而达到强制排气的目的。下面我们来看一下罗茨鼓风机的参数参考：

Roots blower is a fixed volume rotary gas powered machinery. The cylinder is enclosed by a casing and two end wall panels. A pair of impellers that "bite" each other (because there is a gap, the two impellers do not directly contact) separate the intake and exhaust ports. Through the rotation of a pair of synchronous gears, the two impellers rotate in opposite directions at a constant speed in the cylinder. During the rotation process, the gas in the intake port is continuously pushed by the impellers to the exhaust port, thus achieving the purpose of forced exhaust. Let's take a look at the parameter reference of Roots blower below:

1、风量在单位时间内流进风机的实际气体量，常用单位有m³/min。

1. The actual amount of gas flowing into the fan per unit time, commonly measured in meters per minute.

2、风压即风机的全压，常用单位为kpa、mmaq等。罗茨鼓风机

2. Wind pressure refers to the total pressure of a fan, commonly measured in units such as kPa and MMAQ. blower

3、输出速度风机输送风量的速度，单位为米/秒（m/s）。

3. Output speed: The speed at which a fan delivers air, measured in meters per second (m/s).

4、进口处的气体密度罗茨风机进口的空气/气体的密度/单位容积的质量，单位为kg/m³。

4. The gas density at the inlet of the Roots blower is the density of the air/gas at the inlet divided by the mass per unit volume, measured in kg/m ³.

5、风机所处的高度风机安装时所处的海拔高度，单位为米。

5. The altitude at which the fan is installed, measured in meters.

6、气体的自然属性罗茨鼓风机输送的气体是否有腐蚀性、刺激性、易燃性等。

6. The natural properties of gas: whether the gas transported by Roots blower is corrosive, irritating, flammable, etc.

7、风机的类型和布置风机安装时要考虑到风的输入输出的位置，进出口管道的尺寸和轴承的位置等。

7. The type and layout of fans should take into account the position of wind input and output, the size of inlet and outlet pipelines, and the position of bearings when installing fans.

那么罗茨鼓风机要多久保养一次

So how often should the Roots blower be maintained

1.根据现场环境来定时清洗

1. Regularly clean according to the on-site environment

2.启动时按时检查邮箱的位置和油质，及时添加和更换，机器运行一个月要换一次齿轮油。三个月后需要换第二次新油。换油周期可根据油品质量确定，但不能超过半年。

2. Check the position and oil quality of the mailbox on time during startup, add and replace it in a timely manner, and change the gear oil once a month after the machine runs. We need to change the oil for the second time in three months. The oil change cycle can be determined based on the quality of the oil, but cannot exceed six months.

3.罗茨风机首次运行24小时，三角皮带松紧调整一次；3-4天后，第二次调整皮带松紧；一周后调整皮带三次；一个月后再调整。以后注意观察，发现异响、大电流及时检查皮带松紧度。

3. After the first 24 hours of operation of the Roots blower, adjust the tension of the V-belt once; After 3-4 days, adjust the tightness of the belt for the second time; Adjust the belt three times after one week; Adjust again in one month. Pay attention to observation in the future, and promptly check the tightness of the belt if any abnormal noise or high current is found.
