1. Select a reasonable installation position, reduce elbows, and make the water outlet face the pool.

2.縮短管路。

2. Shorten the pipeline.

3.擴(kuò)大出水管徑。

3. Enlarge the outlet pipe diameter.

4.在進(jìn)水可以保持清潔的情況下，可以去掉濾網(wǎng)。

4. The filter screen can be removed when the water inlet can be kept clean.

5.調(diào)整軸向間隙，防止葉輪口環(huán)和軸向間隙的不恰當(dāng)，使用的時(shí)候根據(jù)水泵的出廠說(shuō)明進(jìn)行調(diào)整。

5. Adjust the axial clearance to prevent improper impeller ring and axial clearance. When using, adjust according to the factory instructions of the water pump.

6.及時(shí)管道堵塞物。留在進(jìn)水管、葉輪或者導(dǎo)流殼流道里面的異物。

6. Timely remove pipe blockages. Remove the foreign matters left in the inlet pipe, impeller or flow passage of the guide housing.

7.防止水泵進(jìn)氣。水泵如果進(jìn)了空氣，出水量就會(huì)減少，需要對(duì)各個(gè)密封部件進(jìn)行檢查維護(hù)。

7. Prevent the water pump from entering the air. If air is fed into the water pump, the water output will be reduced, and all sealing parts need to be inspected and maintained.

水深越深，壓力越高，羅茨鼓風(fēng)機(jī)需要的電機(jī)功率就越大，所以水深會(huì)直接影響到羅茨鼓風(fēng)機(jī)的選型。并且隨著水深的增加，對(duì)羅茨鼓風(fēng)機(jī)的性能要求也越大，相對(duì)應(yīng)的風(fēng)機(jī)也越高，所以在購(gòu)買羅茨鼓風(fēng)機(jī)時(shí)一定要選擇性價(jià)比高的型號(hào)。水深超過(guò)10米以上屬于高壓狀態(tài)，對(duì)羅茨鼓風(fēng)機(jī)的性能要求也會(huì)更高。在這個(gè)時(shí)候一般采用雙級(jí)串聯(lián)羅茨鼓風(fēng)機(jī)會(huì)比較合適，普通的羅茨鼓風(fēng)機(jī)一般滿足不了要求。在羅茨鼓風(fēng)機(jī)選型時(shí)，不要只看壓力值，而且還要關(guān)注風(fēng)量的大小，只有風(fēng)量和壓力相匹配才能夠使用，對(duì)于羅茨鼓風(fēng)機(jī)來(lái)說(shuō)，只有保證風(fēng)量的持續(xù)和穩(wěn)定才能夠滿足日常需求

The deeper the water depth, the higher the pressure, the greater the motor power required by roots blower, so the water depth will directly affect the selection of roots blower. In addition, with the increase of water depth, the performance requirements for roots blowers are greater, and the corresponding fan price is higher. Therefore, when purchasing roots blowers, you must choose a model with high cost performance. If the water depth is more than 10m, it belongs to the high pressure state, and the performance requirements for Roots blower will be higher. At this time, it is generally appropriate to use two-stage series roots blower, and ordinary roots blower can not meet the requirements. In the selection of roots blower, we should not only focus on the pressure value, but also pay attention to the air volume. Only when the air volume and pressure match can we use it. For roots blower, only when the air volume is continuous and stable can we meet the daily needs
