| 一、概 述
SH型泵系单级、双级、泵壳中开的卧式离心泵，供吸送清水或物理化学性质类似于水的其它液体，被吸收送液体最高温度80℃。
SH型泵的流量为110～12500米³/时，扬程为10.6～140米，适用于工厂、矿山、城市给水、电站、水利工程、农田灌溉及排涝等。
型号意义
二、结构说明
从联轴器端看，SH型泵均为逆时针方向旋转，用户如需要顺时针方向旋转的泵，必须在订货时特殊提出。
SH型泵的主要零部件有：泵体、泵盖、叶轮、轴、双吸密封环、轴套、轴承部件与联轴器部件等。
泵壳制成水平中开，泵的吸人口与吐出口均铸在下半部泵体上，泵盖以螺尾锥销定位，与泵体配合，检查泵壳内部时，只要拆开泵盖，毋须拆卸进出水管路。泵体的进出水法兰上，有安装真空表与压力表的管螺纹孔。在进出水法兰的底部有放水用的螺塞。
叶轮经过静平衡校验，由键、轴套与两侧轴套螺母固定在泵轴上，其轴向位置用轴

I. Gereral
Series SH pumps are single
stage, double suction with horizontally split casings. They are suitable for pumping
clean water or liquid similar to it in physical and chemical properties at a
temperature not exceeded 80℃.
Series SH pumps are
available for capacities of 110-12500m³/h and heads of 10. 6-140m. They are adoptable
in factories, mines, water works, power stations, hydraulic engineerings,
irrigation or drainage services in agriculture, etc.
The meaning of the model:
Ⅱ.
Construction
Viewed form the driving
end, all the SH pumps are rotating
in counter- clockwise direction. Pumps of clockwise rotation can only be supplied
upon special request.
The main components of SH
pump are listed as follows: lower half casing, upper half casing, impeller, shaft,
wearing rings, shaft sleeves, bearing housings and couplings.
The volute casing is split
on the horizontal center line ,with the/suction and discharge nozzles cast integral
with the lower half. The upper casing is accurately located on the lower half
by the use of dower pins. It can be removes to inspect the interior of the pump
without disturbing the pipe connections or pump alignment. The suction and
discharge flanges contain tapped holes for vacuum and pressure gauge. At the bottom
of the flanges, there are tapped plugs for water drainage.
The impeller has been
balanced statically. It is
