安裝使用說明
一、特別提示：
泵的安裝須由經過培訓的，對水泵安裝富有經驗的人員進行。
二、一般要求：
（一）泵與電機聯軸器的軸向和徑向偏差不超過0.04mm，每次在聯軸器的兩端均勻旋轉量具90°，用游標卡尺或千分尺檢查，所有點的讀數必須均勻。
（二）不允許將泵作為管路的支點，管路在靠近泵的地方應設可靠支撐，泵與管路連接處不允許傳遞任何應力和變形。管路的公稱直徑必須大于或等于相應泵的口徑，必須用適當的方法補償的熱路膨脹，使泵不受額外的負載。
1、泵的安裝和調整
泵的安裝須由經過培訓的，對水泵安裝富有經驗的人員進行。
安裝形式：
1、測量并記下泵的位置。
2、把泵電機機組放在基礎上，地腳螺栓插入基礎中并調整。基礎和底座之間保留4-5mm間隙。
3、對基礎螺栓灌漿并讓其堅固。
4、基礎堅固后均勻地擰緊地腳螺栓。
5、調整并對底座灌漿。
2、軸承潤滑
軸承在制造廠已加油脂、起動前檢查軸承，如果在運輸和儲存中有雜質進入軸承或油脂已凝結固化或油脂已泄漏，起動前必須更換油脂。
軸承至多運行兩年后必須更換油脂。每次更換油脂必須拆除軸承。更換油脂前用汽油或類似的介質清洗軸承、軸承體和軸承壓蓋，并擦干凈。在球軸承和滾珠軸承中完全填料油脂，而在軸承壓蓋中只填充一半油脂。用油槍在軸承體上部的油嘴中加油。
滑動軸承用介質或外接水源潤滑，為防止軸承堵塞，每運行8000小時或至多兩年后，必須清潔軸承，并確保潤滑管路暢通。
OPERATION AND MAINTENANCE INSTRUCTION MANUAL
● Caution: Installation of pumps must be expert and correlative train.
● General Require:
(Ⅰ) Axial and Radial clearance of pump and motor coupling less than 0.04mm. Use of the vernier caliper or micrometer inspect both the end of coupling that equal rotate instrument 90o,every point read data must be equally.
(Ⅱ) Pump shall not be pivot of pipeline and pipeline must be set of fit support against pump. The joint of pump and pipeline can’t transmit any stress and distortion. nominal diameter of pipeline must be excess or equal diameter of pump, and drop suitable method for heat expansion of equalize pipe and loading of superfluity.
1. Installation and adjustment of pump
Caution: Installation of pumps must be expert and correlative train.
Installation Type
(1) Measure and writing position of pump
(2) Pump unites put on base floor, anchor bolts insert base floor and adjustment. Remain 4~5mm between base floor and bedplate.
(3) Grouting base bolts and fitting.
(4) After base tightness, equally screw anchor bolts.
(5) Adjust and Grouting the bedplate.
2. Bearing lubrication
Bearing already fill oil in manufacture and before start-up check bearing. If bearing or oil grease already freeze or leaking in transmit or store. Please alter oil before start-up.
Bearing must be change oil grease after operation two years. Each time change oil grease must disassembly bearing. Before change oil grease, use of gasoline or similar medium clear bearing. Bearing body and bearing gland, fill over oil grease the ball bearing, but the bearing gland just fill half capacity. Use of the oil gun fill the top of bearing body in nozzle. Slip bearing use of medium or connect external water for protect bearing block. After operation 8000 hours or more two years, must be clear bearing for lubrication pipeline expedite。
3、軸封的維護
如果軸封大量泄漏或長時間停機，泵啟運前要安裝或更換填料。泵運行時填料函處有少量滴水，填料壓得太緊會使軸套發熱并磨損，因此填料必須輕輕地、均勻地壓緊。
機械密封：機械密封無需特別維護，每天檢查它是否發熱。如果機械密封明顯泄漏，拆開并檢查，必要的話更換機械密封。

起動
－如果沒有止回閥就關閉出口閥；
－安全打開進口閥（如果有的話）；
－如果有的話，打開軸封和軸承的外接水源閥門；
－泵一開始泵水、壓力表壓力就上升，慢慢打開出口閥，使泵在規定的參數范圍內工作。
泵只有在起動和停止的時候關閉出口閥，否則泵將發熱或損壞。
－關閉出口管路中的截止閥；
－如果出口管路中有止回閥，則截止閥可以維持打開狀態以得到一個回壓；
－關閉電機；
－關閉輔助管路；
－如果有冷卻水的話，等泵冷卻后再關閉。
－如果發生霜凍或長時間停車，排空水泵和冷卻腔（如果有的話），或者采取其它防凍措施。如果泵配的是填料密封，拆除填料。如果泵處理的是污水，為防止在停車期間被腐蝕，排安并沖洗。
7、維護/運行管理
泵運行時應保持平穩，否則軸承和軸封將會損壞，泵不允許干運行。泵不能長時間在出口閥關閉的情況下運行。軸承最高溫度允許超出環境溫度50℃，或不超過90℃。
在泵運行時，輔助管路中的閥門必須保持打開。如果泵配的是填料密封，運行時應有少量滴水，填料壓蓋應輕輕地壓緊。
定期檢查備用泵，確保泵能正常運行，定期轉動泵軸。定期檢查聯軸器部件，一經發現磨損即行更換。外接密封、冷卻和潤滑水必須高出進口壓力1.2～2.0bar。
Start-up
If haven’t check valve that close outlet valve.
Open inlet valve (if exist)
If exist, open shaft seal and external connect water valve of bearing.
Open the power resource.
Pump start-up suction water so that pressure of pressure gage rise. Then slowly open outlet valve for pump working in normal parameter rang.
Pump close outlet valve only just start-up and shut off, whether pump shall be overheat or damage.
Shut-off
Close check valve of outlet pipework.
If outlet pipework have check valve, so that check valve can remain open state for a return pressure.
Close motor
If exist，close inlet valve.
Close Aux. Pipework
If cooling water exist，after pump cooling then close.
If occur frost or long time stop operation that drain pump and cooling house(if exist) or adopt another method for protect frost. If pump is packing seal that disassembly packing. If pump deal with sewage that drain empty and flush for prevent corrupt when stop operation period.
7. Maintain/operation management
Pump remain placidity in operation otherwise bearing and shaft seal shall be damage and pump don’t empty operation in outlet close consider. Max temperature of bearing allow to excess ambient temperature 50℃ or less than 90℃.
Valve of Aux. Pipework must be remaining open in operation. If pump drop packing seal that have litter drop water and packing gland shall be gently tie.
Regular inspect stand pump and rotating pump shaft for pump normal operation. Regular inspect coupling parts, seek wear as soon as alter pressure of external connect seal, cooling and lubrication must high than inlet pressure 1.2~2.0 bar.
