关于山东螺旋风管设备的测定首要能够从三部分来进行剖析。首要，要熟悉并把握如何正确运用风机功能测定设备，测定风机的功能；其次就是要把握试验的详细方法和操作过程；后是实践进行测定，而且把测得的成果转换成特性曲线，以及换算成参数。
The measurement of Shandong spiral duct equipment can be analyzed from three parts. First of all, we should be familiar with and grasp how to correctly use the fan function measuring equipment to determine the fan function; second, we should grasp the detailed method and operation process of the test; finally, we should measure the results in practice, and convert the measured results into characteristic curves and parameters.
螺旋风管的功能很重要，因为其将会直接关系后后期设备的运用作用。因而咱们在选用螺旋风管之前，需求先对其的功能进行测定。这样能够充分了解设备的详细功能，然后能够合理的来运用它，来为咱们效劳。接下来咱们就一同来了解下这方面的详细内容。
The function of the spiral duct is very important, because it will directly affect the operation of later stage equipment. So before we choose the spiral duct, we need to measure its function first. In this way, we can fully understand the detailed functions of the equipment, and then use it reasonably to serve us. Next, let's learn more about the details.
通常情况下，在对螺旋风管设备进行功能检测的时分，还需求运用到专用的检测设备。比方关于风机风量的检测仪器一般是选用锥形进口集流器来进行丈量，其间试验风管则首要包含有测验管路、节流网及整流栅等。一般是使用联通管，将压力计与试验风管的测压力孔进行衔接。
Usually, when testing the function of spiral duct equipment, special testing equipment is also needed. For example, the measuring instruments for fan air volume are usually conical inlet collectors, during which the test air pipes mainly include test pipes, throttle networks and rectifier grids. In general, the use of Unicom pipe, the pressure gauge and the test tube pressure hole to connect.
需求留意的是，在进行衔接之前，需求先检查一下测压管路是否存在漏气现象，如有则不能运用，必须要进行修整。然后在测力矩力臂上加上砝码，使得力臂能够保持水平。把待检测的螺旋风管放置好，然后启动电机。力臂如果不是水平状况，那么再加砝码，直水平停止，然后把空载力矩记录下来。
Needs to note that before the connection, the need to check whether there is leakage phenomenon in the piezometric pipeline, if there is no use, must be repaired. Then the weights are added to the torque arm to keep the lever arm level. Place the spiral air duct to be checked and start the motor. If the arm is not in the horizontal state, then add weights until the horizontal stop, and then record the no-load moment.
在通过试验丈量之后，应当依据所测得的数据成果进行整理和计算，然后制作出螺旋风管的空气动力功能曲线。也能够把试验过程中得到的参数，转换成无因次量，然后制作出螺旋风管的无因次功能曲线。
After the test measurement, the aerodynamic function curve of the helical duct should be made after sorting out and calculating according to the measured data. The parameters obtained during the test can also be converted into dimensionless variables, and then dimensionless function curves of spiral ducts can be made.
