使用泡沫泵時(shí)，需要注意以下幾點(diǎn)：

1. 啟動(dòng)前將泡沫泵排出閥門(mén)打開(kāi)，吸入閥門(mén)關(guān)閉，待泡沫泵達(dá)到全轉(zhuǎn)速時(shí)，方可啟動(dòng)。

2. 啟動(dòng)后應(yīng)逐漸打開(kāi)吸入閥，使液體進(jìn)入泵內(nèi)，直至完全浸沒(méi)葉輪為止。

3. 停止時(shí)應(yīng)先將吐出閥門(mén)打開(kāi)，使液體流出泵外，然后再停止電動(dòng)機(jī)。

4. 運(yùn)轉(zhuǎn)中應(yīng)注意觀察各部軸承的溫升情況，如有異?，F(xiàn)象應(yīng)立即停車(chē)檢查。

5. 使用環(huán)泵式比例混合器時(shí)，如水源為消火栓等壓力水源，壓力水必須先加入水罐減壓后再供環(huán)泵式比例混合器使用。

When using the foam pump, pay attention to the following points:

1. Before starting, open the discharge valve of foam pump and close the suction valve. When the foam pump reaches full speed, it can be started.

2. After starting, the suction valve should be gradually opened to allow liquid to enter the pump until the impeller is completely submerged.

3. When stopping, the discharge valve should be opened first to allow the liquid to flow out of the pump, and then the motor should be stopped.

4. During operation, attention should be paid to observing the temperature rise of each bearing. If there are any abnormalities, the machine should be stopped immediately for inspection.

When using a ring pump proportional mixer, if the water source is a pressure water source such as a fire hydrant, the pressure water must first be added to the water tank for pressure reduction before being supplied to the ring pump proportional mixer.
