二、結(jié)構(gòu)說明
SBM系列泵為單級雙吸軸向中開蝸殼式離心泵，可供臥式或立式安裝．臥式泵的驅(qū)動端可根據(jù)需要設(shè)置在泵的左側(cè)或右側(cè)．也就是同一轉(zhuǎn)子部件可用于順時針、逆時針兩個方向：
SBM型泵的主要零部件有：泵體、泵蓋、葉輪、軸、密封體、泵體密封環(huán)、軸套、軸承部件與聯(lián)軸器部件等。
泵殼制成水平中開,泵的吸人口與吐出口均鑄在下半部泵體上。泵殼下半部分的進(jìn)出口

I. General
Series SBM pumps are single stage,
double suction with horizontally split casings. They are suitable for pumping
unsettled water, clean water, non-drinkable or hydrocarbon at a temperature not
exceeded 105℃,for SBML
is not exceeded 80℃.
Series SBM pumps are available for
capacities of 68- 11O00m³/h and heads of 7-200m. they are adoptable in water works, irrigation and drainage pumping
stations, power stations, industrial water supply systems, fire. fighting systems, arine applications as well as general
applications in refineries, etc.
The nomenclature of the model is
based on its size and characteristic. For example:
Ⅱ.Construction
Series SBM pumps are single
stage, axially split volute easing pump with double flow radial impeller, for horizontal and verical installation.
Drive shaft end of the horizontal pump can be optionally on the left or right
side.
The main components of SBM
pump are listed as follows: lower half easing, upper half easing, impeller, shaft,
wearing rings, shaft sleeves, bearing housings and couplings.
The volute casing is splited
on the horizontal center line with the suction and discharge nozzles east
integral with the lower half. The upper easing is accurately located on the
lower half by the use of dowel pins. It can be removed tb inspect the interior
of the pump without disturbing the pipe connections or pump
