1、泵的安裝和調(diào)整

泵的安裝須由經(jīng)過培訓(xùn)的，對水泵安裝富有經(jīng)驗(yàn)的人員進(jìn)行。

安裝形式：

1、測量并記下泵的位置。

2、把泵電機(jī)機(jī)組放在基礎(chǔ)上，地腳螺栓插入基礎(chǔ)中并調(diào)整?；A(chǔ)和底座之間保留4-5mm間隙。

 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(hù)

如果軸封大量泄漏或長時間停機(jī)，泵啟運(yùn)前要安裝或更換填料。泵運(yùn)行時填料函處有少量滴水，填料壓得太緊會使軸套發(fā)熱并磨損，因此填料必須輕輕地、均勻地壓緊。

機(jī)械密封：機(jī)械密封無需特別維護(hù)，每天檢查它是否發(fā)熱。如果機(jī)械密封明顯泄漏，拆開并檢查，必要的話更換機(jī)械密封。

4、拆卸

只要拆開泵蓋，不必拆卸進(jìn)出水管路，就能拆除整個轉(zhuǎn)子部件；

3. Main of shaft seal

If shaft seal lot of leaking or long time shut-off, so that installation equipment or change packing. Stuff box have little drop water when operation. If packing pressures more tie that shaft sleeve heat and wearing. Packing must be given gently and equally pressure machine seal. Machine seal needn’t special maintain but whether every day shall be overheat. If machine seal have observe leaking, disassembly and check , if necessary, change machine seal.

4. Disassembly

Just disassembly pump cover, don’t disassembly inlet and outlet pipework, it’s disassembly whole rotating parts.

(1) Shut-off inlet and outlet pump cover, then open drain water screw plug. And drain water and gas.

(2) Loosen fitting parts between pump coupling and motor coupling.

(3) Loosen and extrude packing cover.

(4) Loosen joint bolts between pump cover and pump body then remove pump cover.

(5) Loosen joint bolts between bearing body and pump body then disassembly rotating parts.

(7) Loosen nut, pressure bearing body from shaft. The bearing body including bearing, comfier pressure equally. Don’t use of hammer whether damage bearing.

(8) Disassembly packing, packing ring and gas    then loosen shaft nut, disassembly shaft sleeve.

It’s clearance assort between Impeller and shaft so that impeller easily disassembly. If not, use of wood hammer beat impeller hub.

5. Renew assembly

Renew assembly according to counter disassembly circulate. It’s according to installation and assembly workmanship assembly and disassembly oil seal. Bearing and pump body, impeller seal ring.

Before assembly pump cover in order to prevent packing ring enter stuff box so that packing ring coherent packing gland.

Confirm pump, motor and shaft end of pump and motor together, shaft not extrude.

6. Operation /start-up/shut-off

Prepare

Before start-up, the pump must be perfect drain gas and fill medium and check valve of inlet pipeline must be suitable open.

Note: Pump can’t empty operation safely open Aux pipeline (flush, seal, cooling liquid etc.) and check capacity.

Check bearing lubrication and shaft seal

Check rotating direction.

Motor direction must be same direction with arrowhead of pump casing. Before connect motor, inspect direction of pump.

起動

－如果沒有止回閥就關(guān)閉出口閥；

－安全打開進(jìn)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(guī)定的參數(shù)范圍內(nèi)工作。

泵只有在起動和停止的時候關(guān)閉出口閥，否則泵將發(fā)熱或損壞。

－關(guān)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(tài)以得到一個回壓；

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.
