LG 型立式多级泵系立式单吸多级分段式离心泵，是从卧式多级离心泵基础上进行优化设计和制造。 DL and LG vertical multi-stage pumps are vertical single-suction multi-stage segmented centrifugal pumps, which are optimized design and manufacture based on horizontal multi-stage centrifugal pumps. JB/T72727-93 的要求，供输送常温清水及物理化学性质类似于清水的介质，介质温度 -15 ℃ ~120 ℃。 It meets the requirements of national standards, JB / T72727-93 , and can be used to transport normal temperature water and media with physical and chemical properties similar to water. The temperature of the medium is -15 ℃ ~ 120 ℃.
Conditions of Use:
This series of pumps are especially suitable for water supply, drainage and fire fighting water for high-rise buildings, hospitals, hotels, department stores, office buildings, long-distance transportation and water used in production process cycles.
Structural characteristics and working principle:
）本系列泵在结构上采用了立式、分段形式，且运转安全、平稳，寿命长、扬程高、占地面积小、安装维修方便。 1 ) This series of pumps adopt vertical and segmented structure, and they are safe and stable in operation, long life, high lift, small footprint, convenient installation and maintenance.
2 ）泵的吸入口在下方，出水口在上方，其相对位置可根据用户的要求选择 0° 、 90° 、 ( 2 ) The suction port of the pump is below and the outlet of the pump is above. The relative position can be selected according to the requirements of the user: 0 ° , 90 ° ,
、 270° 之一进行装配，一般泵 180° 出厂。 It is assembled at one of 180 ° and 270 ° . Generally, the pump is delivered at 180 ° .
3 ）采用低噪音轴承，故整机运转时噪音很低，振动很小，大大改善了作业环境，提高了使用寿命。 ( 3 ) Low-noise bearings are used, so the machine runs with low noise and small vibration, which greatly improves the working environment and the service life.
