CAY型磁力驱动离心油泵，旨在输送不含固体颗粒的石油、液化气等要求无泄漏或不允许密封污染的介质，特别是输送高温、高压、易燃、易爆或有毒的液体。适合于石油精制、石油化工和化学工业等工业系统中。

CAY型泵是在AY型油泵基础上改造设计的无泄漏全密封磁力泵，其结构形式、安装尺寸和性能参数范围与AY油泵相同。

CAY magnetic driven centrifugal oil pump is designed to convey media such as petroleum solid particle free and LPG requiring freedom of leakage or no contamination by sealing, especially high temperature, high pressure, inflammable and explosive or toxic liquid. It is suitable for service in petroleum refining, petrochemical and chemical industrial systems.

CAY pump is a leakage free and fully enclosed magnetic pump renovated and designed on the basis of Model AY oil pump, and its structural form, installation dimensions and performance parameter ranges are identical to those of AY oil pumps.

结构说明 Structure of CAY

1.CAY型泵为单级/两级单吸悬臂式离心油泵，磁力驱动全密封，无泄漏。

2.壳体径向剖分，泵安装的支撑面在轴心线的水平面上，泵的进出口均垂直向上。

3.泵的轴向力由叶轮上的平衡孔或叶轮对称布置达到平衡，残余轴向力由推力轴承来承受。

4.内置滑动轴承的润滑方式为工艺液体自润滑。

5.外部轴承体外表面铸成有散热片，输送介质温度小于120℃时，可采用空气冷却，温度在120～260℃之间，可选用风扇冷却，温度大于260℃时应采用水冷却。

6.采用膜片式加长联轴器部件，以便于检修。

7.从原动机端看，泵为逆时针方向旋转。

1.CAY pump is single/two-stage single suction cantilever centrifugal oil pump, driven by magnetic force, fully enclosed and free of leakage.

2.The casing is split radially; the pump mounting support surface is on the horizontal plane of the axial line, and both inlet and outlet of the pump face vertically upwards.

3.The axial force of the pump is balanced by the balance holes on the impellor or symmetric arrangement of impellor, and the residual thrust is taken by the thrust bearing.

4.The built-in sliding bearings are self-lubricated by process liquid.

5.The outer surface of external bearings is cast with radiating fins, and it can be cooled by air when the temperature of conveying liquid is below 120℃, by fan when the temperature is between 120~260℃, and should be cooled with water when the temperature is over 260℃.

6.Diaphragm extended coupling is used to facilitate maintenance.

7.The pump rotates in anti-clockwise direction when viewed from the primer side.
