混流泵
HW型蝸殼式混流泵按國家標準 新系列而設計的節能產品。其性能指標均達到國 先 水平,省材節能效果顯著。
HW Spiral Mixed-flow Pump is an efficient pump designed by latest
national standard.The performance indexes have been upto the international
advanced level and the material and energy saving result is remarkable.

3、安裝基礎:要求土質堅實牢固。
4、水泵安裝時,必須保證泵軸的水平位置。
5、進水管末端應浸入水平面以下一米左右,但須離開泥底半米左右。
6、水泵安裝好后,計算允許吸上高度和揚程,在水位穩定的條件下,要求為規定數量值的0.8~1.2倍范圍,否則水泵不會正常運行
I.
Installation Principle
1. Installation
Height: Cidering the height according to the rainy season or dry season.The suction
vacuum
height can
not be higher than the adsorbing height.
2. Installation
Location:The location is better to close to the water source as p as
can.It should be not
only
keeping the safety but also shortening the water inlet pipe and reduce the
headloss
3.
Installation base:The soil texture should be firm and solid.
4.
During installation, keep the pump axile in horizontal p ition.
5.The end of
water inlet pipe should be immersed under water in about one meter and far away
from the end of mud in about half meter.
6.After installing the pump,calculate the
suitable suction height and head.Under the stable water level condition,
S型泵性能范圍流量160~18000立方米/時,揚程12~125米,進水口直徑150~1400毫米,轉速2950、1450、970、730、585、485、360轉/分。
(1)D型泵性能范圍 流量6.3~720立方米/時,揚程16~600米,進水口徑:50、75、100、125、150、200毫米,其中50~125毫米泵型為高轉速2950轉/分,150~200毫米泵型轉速為1480轉/分。
(2)結構型式 D型多級離心泵為臥式多級(2~12級),葉輪為單吸,泵體為分段式。當首級葉輪為雙吸時,用DS表示,當同時規定有兩種轉速時,低速用DA表示,用于鍋爐給水的多級離心泵,用DG表示。
