产品概述Product description Imported horizontal single-stage single-suction centrifugal pump water, is the joint design of energy-saving pump, which is the other single-stage centrifugal pump water newer. Advantages are: a full range of hydraulic performance and reasonable layout, the user selects the range, easy maintenance; efficiency and suction lift up to international advanced level average. This pump is suitable for industrial and urban water supply, drainage, irrigation and agriculture can also be used for conveying water or physical and chemical properties similar to water or other liquids, the temperature is not high 80 ℃.
进口卧式单级单吸清水离心泵，是全国联合设计的节能泵，它是其他单级清水离心泵的更新型。优点有：全系列水力性能布局合理，用户选择范围宽，检修方便；效率和吸程达到国际平均水平。本型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℃。
2、进口卧式单级单吸清水离心泵的泵体和泵盖部分，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、泵的壳体(即泵体和泵盖)构成泵的工作室。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、泵的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、泵的传动方式是通过加长弹性联轴器与电动机联接的，泵的旋转方向，从驱动端看，为顺时针方向旋转。
1, imports of horizontal single-stage single-suction centrifugal pump water based on performance and size ISO2858 international standard provisions designed mainly covered by the pump, pump, impeller, shaft seal rings, bushings, bearings and suspension but not other components.
2, imports of horizontal single-stage single-suction centrifugal pump water pump body and pump cover part of the back office split from the impeller, that is commonly referred to as post-formal-door structure. The advantage is easy maintenance, repair does not move when the pump, suction line, discharge line and the motor, just remove the spacer coupling intermediate coupling member, you can exit the rotor parts for maintenance.
3, the pump housing (ie, pump and pump cover) constitute the pump studio. Impeller, shaft and rolling bearings as the pump rotor. Suspension bearing member supporting the rotor portion of the pump, the rolling bearing by radial and axial forces of the pump.
4, in order to balance the axial force of the pump, the impeller of the pump before the most, after the sealing ring has, in the rear cover plate is provided with an impeller balance holes, due to force some small shaft, the impeller is not provided on the back of the seal rings and balance holes.
5, pump axial seal ring is composed of packing gland, packing ring and filler and other components to prevent water leakage into the air or a lot. If the pump impeller balance is equipped with wadding impeller inlet in communication with the cavity, impeller inlet of liquid in a vacuum, it is very easy along the surface of the intake sleeve, so the packing chamber equipped with packing rings by hole pump cover, the pump chamber pressure of water lead to the packing ring seal. If no pump impeller balance holes, due to the back of the impeller fluid pressure greater than atmospheric pressure, so there is no leakage problems, it is time to install packing rings.
6, to avoid shaft wear in the shaft through the packing chamber parts fitted sleeve protection. Associate O-ring between the sleeve and the shaft to prevent along the mating surface of the intake or leaking.
7, the pump drive is through lengthened flexible coupling and motor coupling, rotation direction of the pump from the drive end, clockwise rotation.
