PQDW卧式多级泵系列
|
| |
PQDW型多级离心泵系列卧式、单吸多级、分段式结构，是最新开发生产的节能系列产品， PQDW型多级离心泵系列对TSW型多级离心泵 进行重大技术改造后的新产品。其性能参数及技术指标有较大提高，具有效率高、运行噪声低、抗汽蚀性能好、结构合理、使用寿命长等优点。
PQDW型多级离心泵全系列共有5个品种40个规格，其性能范围流量Q=1.5-191M3/H，扬程H=17-247M，转速N=1450R/MIN。
PQDW型多级离心泵可供输送80℃以下的清水或物理、化学性质类似于水的液体，广泛适用于城市建筑、工厂的给排水，尤其适用于宾馆、饭店娱乐场所的制冷、空调给水。 |

| 主要特点： |
| |
1.泵结构紧凑、布置合理、外形美观。
2.进、出口径相同，便于管路连接。
3.泵运行平稳、噪音低、寿命长。
4.密封可靠、无泄漏。
5.流量和扬程可根据需要增减泵级数并结合切割叶轮外径予以满足。 |

| 工作原理： |
| |
PQDW型单吸多级分段式离心泵，其吸入口为水平方向，吐出口为垂直向上布置。本系列共有5种口径，用户可根据流量、扬程的需要选择不同口径、不同级数的泵予以满足。
泵由壳体部件和转子部件所组成。壳体部件由进水段、中段、平衡盘和轴套等组成。转子两端支承在油脂润滑的滚动轴承上。
进水段、中断和出水段的结合面用纸通过拉紧螺栓拉紧达到密封。为防止水让两端出轴泄漏，设有填料密封，也可采用机械密封，同时在轴上装有橡胶挡水圈、0型橡胶密封圈，以防水进入轴承腔内。
为防止中段和导叶磨损，设有叶轮密封环和导叶套等易损零件，当这些零件磨损到一定程度后，应予更换。
泵和电动机装在公共座上（除150TSW6-9以外），通过弹性联轴器转动。 |
