5、工作過程

首先檢查各管路系統(tǒng)的密封情況，然后將工作水管的閥門打開一點，使混合室內的空氣帶出去，再將吸入管路和工作管上的閥門全部打開，使永噴射泵正常工作，再調至額定工況。

6、全面觀察

(1)檢查所有連接處的密封情況，工作時不得有滲漏現(xiàn)象。

(2)發(fā)現(xiàn)性能下降時，應檢查吸入段各部分的密封情況，檢查泵內部是否有雜物，垃圾積沉或堵塞以及噴嘴是否磨損。

7、保養(yǎng)

(1)水噴射泵在工作完畢后應關閉工作水泵和吸入管路上的閥門。

(2)水噴射泵停止工作后應注意內部的清潔情況，定期清除里面的污泥、鹽類等沉積物及其它雜物。

(3)水噴射泵長期不工作時應進行油封。

E、working process

  First check the sealing condition of a11 the piping system。then open the valve on water tube a little to vent the air in the mixing chamber After that，open all the valve on inlet tube and water tube widely to make the injection water pump operate normally under norminal working condition。

F、A11 round observation

(1)Check the sealing condition in all the joinst and connections，no leakage should be found。

(2)if deterioration in performance is found，check the sealing condition in inlet part and chedk if there is clog wirhin the pump，or if the nozzle is worn。

G、MaIntenance

(1)Close the valve on pump and inlet tube after operation。

(2)keep the interior of pump clean after stopping，clean the clog such as mug and salt and other foreign substance。

(3)Oil seal the pump when laying aside fer a long period。
