b).联轴器与泵机组是否校正;

    C).管路是否按要求连接;

    d).手是否能容易地转动转子;

    e).是否所有轴承都有良好的润滑。

    2)、起动前关闭出口阀,用介质灌注排尽泵和管路内的空气。吸人状况时,用泵体上部的螺塞排气。在倒灌时泵也须排空;

    2、运行:

    1)、当压力表压力升高,慢慢打开出口阀;

    2)、打开所有辅助管路,并检查流量;

    3)、泵是填料密封运行时,填料函处允许有多少量,滴水,轻轻压紧填料压盖至少量滴水。

    4)、为防止介质升温,泵不能在出口阀门关闭的情况下长期运转;

    5)、当周围的环境温度达到30℃时,轴承温度不能超过90℃,当温度再升高量,轴承温度最多不应超过100℃

    6)、使用稀油润滑,要定期检查油位;油脂润滑的深沟球轴承不需要维护。

    7)、检查联轴器上的弹性元件,一旦磨损,应立即更换;

    8)、如果密封、冷却、润滑液不是用工作介质,必须保证使用的液压比进口压力高1.02.0巴。

    3、停止:

    1)、泵停止运转时,先关闭出口阀,然后切断电源;

    2)、关闭辅助管路。泵的轴封即使在停机状量也要用密封润滑油;

    3)、在冰冻或长期停止使用时,应排除泵及管路中的介质,以免冻裂。

    4)、当输送的介质为对健康有害的液体时,应将泵和管路内介质尽快排尽。

    说明:

    Samely,  for the pump set with common bedplate. Fit the pre- assembled set with foun- dation bolts loosely inserted in the cut- outs in the foundation and align. There must be a 4- 5cm gap between the top of the foundation and the bottom of the baseframe. Precisely align the set using the adjusting screws and check alignment on the coupling. Others you can refer to the above mention methods.

ⅩⅢ.Starting, Stopping and Running

    1. Starting:

    1) . Before starting up the pump make sure that  the  following  requirements  have  been checked and fulfilled.

    a) . Has the pump been firmly bolted to the base/foundation?

    b) . Have the coupling and pump unit been aligned as specified?

    c). Are the pipes properly fitted?

    d). Can the unit be easily rotated by hand at the coupling?  (Carry out at least one full rotation)

    e) . Has lubrication been provided for oil -lubricated bearings?

    2) Before the pump is started up, it and the pipes must be vented and filled with the liquid to be pumped. In the case of both gravity feed and suction operation venting must be carried out via the hole on the upper suction elbow. In the case

of suction operation the upum must additionally be evacuated(a vacuum must be created).

    2. Running:

    1) . As soon as the pump starts to deliver this can be recognized by the rising gauge pressure slowly open the delivery gate valve fully.

    2). All additional connections for cooling, heating, lubrication irrigation or sealing liquid etc, if fitted, must be opened fully or switched on and the flow must be checked.

    3). Screw homogenizenously the nuts on the pump packing gland so as to the leakage of liquid is little, at the same time, pay more attention to the packing case temperature rising.

    4). Prolonged operation against a closed shut-off element is not permitted in order to prevent the medium handled from heating up.

    5). At room temperatures of up to 30 the bearing temperature should not exceed 90. At higher room temperature the bearing temperature should be below 1O0.

    6). If the pump features oil-lubricated
