进口清水离心泵原理特点及品牌（图）

进口清水离心泵适用于工业和城市给水、排水，也可用于农业排灌及供输送清水或物理化学性质类似于清水的其他液体之用，温度不高80℃。

产品特点

1、根据国际标准ISO2858所规定的性能和尺寸设计，主要由泵体、泵盖、叶轮、轴、密封环、轴套及悬架轴承不见等组成。

2、泵体和泵盖部分，是从叶轮背面处剖分的，即通常所说的后开门结构形式。其优点是检修方便，检修时不动泵体，吸入管路，排出管路和电动机，只需拆下加长联轴器的中间联接件，即可退出转子部分进行检修。

3、壳体（即泵体和泵盖）构成水泵的工作室。叶轮、轴和滚动轴承等为泵的转子。悬架轴承部件支撑着泵的转子部分，滚动轴承受泵的径向力和轴向力。

4、为了平衡泵的轴向力，大多数泵的叶轮前、后均设有密封环，并在叶轮后盖板上设有平衡孔，由于有些泵轴向力不大，叶轮背面未设密封环和平衡孔。

5、轴向密封环是由填料压盖，填料环和填料等组成，以防止进气或大量漏水。泵的叶轮如有平衡，则装有软填料的空腔与叶轮吸入口相通，如叶轮入口处液体处于真空状态，则很容易沿着轴套表面进气，故在填料腔内装有填料环通过泵盖上的小孔，将清水离心泵室内压力水引至填料环进行密封。泵的叶轮如没有平衡孔，由于叶轮背面液体压力大于大气压，因而不存在漏气问题，故可不装填料环。

6、为避免轴磨损，在轴通过填料腔的部位装有轴套保护。轴套与轴之间准有O型密封圈，以防止沿着配合表面进气或漏水。

7、传动方式通过加长弹性联轴器与电动机联接，泵的旋转方向，从驱动端看，为顺时针方向旋转。

Clean water centrifugal pump for industrial and urban water supply, drainage, can also be used for agricultural irrigation and drainage for the delivery of water or physical and chemical properties similar to other liquids used in water, the temperature is not high 80 ℃.

Features

1, according to the international standard ISO2858 provides the performance and size of the design, mainly by the pump, pump cover, impeller, shaft, seal ring, sleeve and suspension bearings and other components.

2, the pump body and pump cover part, is divided from the back of the impeller, that is commonly referred to as the back door structure. The advantage is easy maintenance, maintenance does not move the pump body, suction pipe, discharge pipes and motors, just remove the coupling of the middle coupling, you can exit the rotor part of the maintenance.

3, the shell (that is, pump and pump cover) constitute the pump of the studio. Impeller, shaft and rolling bearings for the pump rotor. The suspension bearing member supports the rotor portion of the pump, and the rolling bearing is subjected to the radial force and axial force of the pump.

4, in order to balance the pump axial force, most of the pump before and after the impeller is equipped with a seal ring, and in the impeller rear cover with a balance hole, because some pump axial force is not large, the impeller is not sealed on the back Ring and balance hole.

5, the axial seal ring is composed of packing gland, packing ring and packing, etc., to prevent the intake or a lot of water leakage. If the impeller of the pump is balanced, the cavity with the soft packing is connected with the impeller inlet. If the liquid at the inlet of the impeller is in a vacuum state, it is easy to enter the surface along the surface of the sleeve. Therefore, Pump hole on the hole, the water centrifugal pump chamber pressure water lead to the packing ring for sealing. If there is no balance hole in the impeller of the pump, the liquid pressure on the back of the impeller is greater than the atmospheric pressure, so there is no leakage problem.

6, in order to avoid shaft wear, in the shaft through the packing cavity parts with sleeve protection. There is an O-ring between the sleeve and the shaft to prevent ingress or leaking along the mating surface.
