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.

螺旋風(fēng)管的功能很重要，因?yàn)槠鋵?huì)直接關(guān)系后后期設(shè)備的運(yùn)用作用。因而咱們?cè)谶x用螺旋風(fēng)管之前，需求先對(duì)其的功能進(jìn)行測(cè)定。這樣能夠充分了解設(shè)備的詳細(xì)功能，然后能夠合理的來(lái)運(yùn)用它，來(lái)為咱們效勞。接下來(lái)咱們就一同來(lái)了解下這方面的詳細(xì)內(nèi)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.

通常情況下，在對(duì)螺旋風(fēng)管設(shè)備進(jìn)行功能檢測(cè)的時(shí)分，還需求運(yùn)用到專用的檢測(cè)設(shè)備。比方關(guān)于風(fēng)機(jī)風(fēng)量的檢測(cè)儀器一般是選用錐形進(jìn)口集流器來(lái)進(jìn)行丈量，其間試驗(yàn)風(fēng)管則首要包含有測(cè)驗(yàn)管路、節(jié)流網(wǎng)及整流柵等。一般是使用聯(lián)通管，將壓力計(jì)與試驗(yàn)風(fēng)管的測(cè)壓力孔進(jìn)行銜接。

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，在進(jìn)行銜接之前，需求先檢查一下測(cè)壓管路是否存在漏氣現(xiàn)象，如有則不能運(yùn)用，必須要進(jìn)行修整。然后在測(cè)力矩力臂上加上砝碼，使得力臂能夠保持水平。把待檢測(cè)的螺旋風(fēng)管放置好，然后啟動(dòng)電機(jī)。力臂如果不是水平狀況，那么再加砝碼，直水平停止，然后把空載力矩記錄下來(lái)。

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.

在通過(guò)試驗(yàn)丈量之后，應(yīng)當(dāng)依據(jù)所測(cè)得的數(shù)據(jù)成果進(jìn)行整理和計(jì)算，然后制作出螺旋風(fēng)管的空氣動(dòng)力功能曲線。也能夠把試驗(yàn)過(guò)程中得到的參數(shù)，轉(zhuǎn)換成無(wú)因次量，然后制作出螺旋風(fēng)管的無(wú)因次功能曲線。

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.
