安装使用说明
一、特别提示：
泵的安装须由经过培训的，对水泵安装富有经验的人员进行。
二、一般要求：
（一）泵与电机联轴器的轴向和径向偏差不超过0.04mm，每次在联轴器的两端均匀旋转量具90°，用游标卡尺或千分尺检查，所有点的读数必须均匀。
（二）不允许将泵作为管路的支点，管路在靠近泵的地方应设可靠支撑，泵与管路连接处不允许传递任何应力和变形。管路的公称直径必须大于或等于相应泵的口径，必须用适当的方法补偿的热路膨胀，使泵不受额外的负载。
1、泵的安装和调整
泵的安装须由经过培训的，对水泵安装富有经验的人员进行。
安装形式：
1、测量并记下泵的位置。
2、把泵电机机组放在基础上，地脚螺栓插入基础中并调整。基础和底座之间保留4-5mm间隙。
3、对基础螺栓灌浆并让其坚固。
4、基础坚固后均匀地拧紧地脚螺栓。

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、轴封的维护
如果轴封大量泄漏或长时间停机，泵启运前要安装或更换填料。泵运行时填料函处有少量滴水，填料压得太紧会使轴套发热并磨损，因此填料必须轻轻地、均匀地压紧。
机械密封：机械密封无需特别维护，每天检查它是否发热。如果机械密封明显泄漏，拆开并检查，必要的话更换机械密封。

起动
－如果没有止回阀就关闭出口阀；
－安全打开进口阀（如果有的话）；
－如果有的话，打开轴封和轴承的外接水源阀门；
－泵一开始泵水、压力表压力就上升，慢慢打开出口阀，使泵在规定的参数范围内工作。
泵只有在起动和停止的时候关闭出口阀，否则泵将发热或损坏。
－关闭出口管路中的截止阀；
－如果出口管路中有止回阀，则截止阀可以维持打开状态以得到一个回压；
－关闭电机；
－关闭辅助管路；
－如果有冷却水的话，等泵冷却后再关闭。
－如果发生霜冻或长时间停车，排空水泵和冷却腔（如果有的话），或者采取其它防冻措施。如果泵配的是填料密封，拆除填料。如果泵处理的是污水，为防止在停车期间被腐蚀，排安并冲洗。
7、维护/运行管理
泵运行时应保持平稳，否则轴承和轴封将会损坏，泵不允许干运行。泵不能长时间在出口阀关闭的情况下运行。轴承温度允许超出环境温度50℃，或不超过90℃。
在泵运行时，辅助管路中的阀门必须保持打开。如果泵配的是填料密封，运行时应有少量滴水，填料压盖应轻轻地压紧。
定期检查备用泵，确保泵能正常运行，定期转动泵轴。定期检查联轴器部件，一经发现磨损即行更换。外接密封、冷却和润滑水必须高出进口压力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.
