常用的农用泵
离心泵
离心泵型号、品种规格及其变型产品在农用泵中是***多的。根据水流入叶轮的方式、叶轮多少、泵身能否自吸以及配套动力大小和动力品种等,离心泵有单级单吸离心泵、单级双吸离心泵、多级离心泵、自吸离心泵、电动机泵和柴油机泵等。
2、轴流泵的一般特点
(1)水在轴流泵的流经方向是沿叶轮的轴向吸入、轴向流出,因此称轴流泵。
(2)扬程低(1~13米)、流量大、效益高,排污混流泵,适于平原、湖区、河区排灌。
(3)起动前不需灌 ,排污混流泵安装,操作简单。
(一)HW型混流泵由泵体、泵盖、叶轮、泵轴和轴承体等主要零件构成。
I. HW Mixed-flow
pump is composed of pump casing, pump cover,排污混流泵维修, impeller, pump spindle and bearing
body mainly.
水泵转向从水泵进水口看叶轮为逆时针方向旋转(即箭头所示方向旋转。)
V. Pump Diversion
Look from inlet of pump, the impeller is
turning clockwise(turning as the direction indicated by rotation arrow)
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,
