Ⅱ 水噴淋系統英文翻譯
One. Overview: The water spray system in support of the main ports of the reactor is expected machinery, ship unloader, and so on the track hanging. The main materials used to remove the pile, unloading, transport equipment in the course of covering the surface of st, st and so on. II. How it works: water spray system by the tanks, single-stage centrifugal pumps, piping, valves manually, one-way valve, pressure gauge, the level gauge glass, solenoid valves, such as the composition of the nozzle. Of the water spray system has three spray, a water tank with high and low level, low-level cease to be the first centrifugal pump, and then quickly connected to the joint, open water solenoid valve (1), the water began. High-level pay off solenoid valve (1), the water stopped. Ship unloader to work, when the hopper is expected to reach great time to open solenoid valve (4), began to spray nozzle to suppress st. When the material arrived straight away when the tube closed solenoid valve (4) and at the same time open the solenoid valve (2), began to spray nozzle to suppress st. When the materials reach the discharge belt machine shut down when the solenoid valve (2) and at the same time open the solenoid valve (3), began to spray nozzle to suppress st, after the closure of the solenoid valve (3). The entire work after the end of the cycle should be based on the work of each cycle between the time the decision to shut down and restart the pump, in general, such as the work of each cycle in more than 10 minutes to stop centrifugal pump, in 10 minutes, then do not have to Centrifugal pump to stop. III. Technical parameters: 1. Single-stage centrifugal pumps: Model ISW65-250, traffic 25m3 / h, head 80m, electric power 15Kw, 415V/50HZ; 2. Pressure system: 0.8Mpa; 3. Flow system: 416.7L/Min ; 4. Nozzle: 32; 5. Tank capacity: 2m3; 6. Float liquid level controller: pressure 1Mpa, voltage 110V, contact capacity 200VA; 7. Solenoid valve: voltage 110AC 50HZ. IV. Debugging: the work before the ship unloader to check on the tank glass of water level, low-level water tank to be filled water, and then to see the front of the centrifugal pump cut-off valve is open, if opened should open the valve Centrifugal pump in order to avoid damage. Ship unloader at work to open centrifugal pump, the medium through a non-return valve, spray pipelines to reach each point, when the expected spray reach the point when the solenoid valve to open at the beginning of spraying water st. Spray in each of the points are setting the solenoid valve by-pass valve for the purpose of the spray at the point when the damage to the closure of the solenoid valve solenoid valve before and after the throttle valve, in parallel to open the throttle, spray can point to normal , At the same time can be solenoid valve repair. Float on the water tank equipped with two liquid level controller, when the water tanks in low-level, low-level alarm float controller, the staff should be open water solenoid valve (1) to start adding water. When the water tank in high-level, high-level controller float sender to close the water solenoid valve (1) to stop adding water. In the system of setting the lowest drainage valve for release before the winter to make the water system. Water tank located at the bottom of the drainage valves (ball), for emptying the water in the tank. In the funnel large platform feeder vibration adapter I expected the Department set up a flushing device, by the ball, rapid joints, hoses, composed of high-pressure water jets. Need to use the washing device should be open centrifugal pump. (A) the use of pump pressure: pressure pumps form chart: 1. Start-up operation: a) hand-FAN BLADE Bozhuan motor, impeller should be no card mill, rotating flexible; b) set by hand pump in order to move lubricating fluid Into the end mechanical seal; c) the exhaust water, open the valve of imports, so full of liquid into the cavity pump until the entire pipeline is full of liquid and ensure the import of seal pipeline; d) the closure of the export valve to rece the starting current; e) to connect power, determine the starting point in the right direction, from the motor FAN BLADE depends on for clockwise rotation; f) to graally adjust the export of the valves open, as far as possible so that the pump's rated the work of state; g) the operation of the pump in the process of Found an unusual noise or sound, immediately inspect stopping; h) normal mechanical seal leakage should be less than 3 drops / min, electrical inspection, the Department bearing temperature rise of <70 ℃, more than the value of the reasons for inspection; i) Access to power, and then graally to normal rotor tube spit on the road to open the valve, the valve in the closed, the pumps working hours in a row can not be more than 10 minutes. 2. Stop: a) spit shut down pipeline valves; b) cut off power to stop motor run; c) close the valve of imports; d) If the ambient temperature below 0 ℃ or pump out the long-term, should pump out water .

Ⅳ 離心泵前端又負壓罐抽不上來水是什麼情況
咨詢記錄 · 回答於2021-08-02
Ⅳ 離心泵帶氣作業，可是沒有排氣閥，該如何處理啊！
理論上離心泵可以輸送的液體含氣量可達到5%。如果泵運轉不穩定，可以在入口（泵法蘭前端）管路加一個排氣管線。入口管路還可以傾斜布置，5度的傾斜角坡向泵，讓氣體自動回到入口罐。入口管路還必須布置合理，不要產生氣囊。
Ⅵ 立式多級離心泵為什麼能疊壓供水即利用前端來水壓力
忽略動能和重力勢能，揚程為H=（p2-p1）/ρg，即出口壓力p2=p1+.....
所有泵都是一樣的，能量守恆，進口壓力能不能無故消失的
Ⅶ 如何將離心水泵改裝成自吸離心泵，如何
本人改過很多了，首先把前端蓋換成自吸泵的端蓋，口徑要一樣，然後再把電機的軸在車床上面改一下，裝配即可
Ⅷ 水泵前端閥門關閉的情況下水泵運轉電機會燒嗎
和泵的結構以及電機配用有關。
在水泵和電機恰好匹配的情況下，純離心泵燒泵的可能性大一些，純軸流泵燒電機的可能性大一些。
Ⅸ 離心泵真空引水罐的容積大小怎樣選擇
10年前我自己做了幾個，一直用到現在，最近想提升自己，看見這個問題就將我思路簡單回復一下：
參照草圖（能看懂就行，o(╥﹏╥)o）
根據理想氣體的波義爾定律P1*V1=P2*V2
P1：常壓（計算用絕壓，我們約取1Bar）
V1：真空罐進口管容積+無效容積
P2：運行時真空罐的壓力，一般是負壓，（例吸程3米，那麼就是0.7Bar）
V2：真空罐進口管容積+無效容積+有效容積
由於實際在運行過程中有多重因素影響（如管道損失、溶解氣體等），所以我把真空罐做得比較大，一般是1.5~2.0的系數
另外就是，初次運行時盡可能將真空罐灌滿水；泵進口前端、水泵泵體及機械密封一定要保證密封性能，泵出口需要安裝止回閥；泵進口管道需要傾斜向下；抽水時控制不能吸空。
其他問題大家一起探討，歡迎評論。
Ⅹ 離心泵泵體常見的結構有哪幾種
離心泵泵體是泵結構的中心，也叫蝸殼或泵殼，其型式也比較多。 1、水平剖分式 這種型式的泵殼是在通過軸心的水平剖分面上分開。拆卸泵殼時與吸入、排出管道無關，維修比較方便。 2、垂直剖分式 這種型式的泵殼是在垂直軸心的垂直面上剖分，不易泄漏，但在維修時必須拆卸進口管道，所以維修不如水平剖分式泵殼方便。 3、傾斜剖分式 這種型式的泵殼是從前端吸入，上面排出，泵殼在通過軸心的傾斜面上剖分，不拆卸吸入和排出管道，只拆開上半部，泵殼即可檢修內部。 4、筒體式 這種型式的泵是把泵殼製作成筒體式的，對於壓力非常高的泵，用單層泵體難以承受其壓力，所以採用雙層泵體。筒體式泵殼能承受較高壓力，其內安裝水平剖分式或 垂直剖分式的轉子，在化肥裝置中高壓的鍋爐給水泵多是筒體式多級離心泵。 若按泵殼的支承型式可分為標准支承式、中心支承式、懸臂式、管道式、懸掛式。 1、標准支承式 這種型式的泵，一般是卧式，在泵體兩側帶有支腳，支腳用螺栓固定在底座上。 2、中心支承式 這種型式的泵，泵殼下側的支腳安裝在底座上，可適應輸送高溫流體而造成熱膨脹應力的影響。 3、懸臂式 這種型式的泵，泵殼是一整體，並將泵體與吸入蓋的組合件安裝在軸承托架上。結構緊湊，拆卸方便。 4、管道式 這種型式的泵是作為管道的一部分和管道聯接在一起的，並由管道支承。檢修時，不需拆下與管道聯接的泵體，就可以檢修離心泵的轉子和電動機。 5、懸掛式 這種型式的泵是泵殼裝在排出管道上，泵殼在排出管以下部分懸掛在吸入容器上，泵殼是垂直剖分式的。
