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.擴大出水管徑。

3. Enlarge the outlet pipe diameter.

4.在進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)，使用的時候根據(jù)水泵的出廠說明進行調(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.及時管道堵塞物。留在進水管、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.防止水泵進氣。水泵如果進了空氣，出水量就會減少，需要對各個密封部件進行檢查維護。

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)機需要的電機功率就越大，所以水深會直接影響到羅茨鼓風(fēng)機的選型。并且隨著水深的增加，對羅茨鼓風(fēng)機的性能要求也越大，相對應(yīng)的風(fēng)機也越高，所以在購買羅茨鼓風(fēng)機時一定要選擇性價比高的型號。水深超過10米以上屬于高壓狀態(tài)，對羅茨鼓風(fēng)機的性能要求也會更高。在這個時候一般采用雙級串聯(lián)羅茨鼓風(fēng)機會比較合適，普通的羅茨鼓風(fēng)機一般滿足不了要求。在羅茨鼓風(fēng)機選型時，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，對于羅茨鼓風(fēng)機來說，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
