CAY型磁力驅(qū)動離心油泵，旨在輸送不含固體顆粒的石油、液化氣等要求無泄漏或不允許密封污染的介質(zhì)，特別是輸送高溫、高壓、易燃、易爆或有毒的液體。適合于石油精制、石油化工和化學(xué)工業(yè)等工業(yè)系統(tǒng)中。

CAY型泵是在AY型油泵基礎(chǔ)上改造設(shè)計(jì)的無泄漏全密封磁力泵，其結(jié)構(gòu)形式、安裝尺寸和性能參數(shù)范圍與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.

結(jié)構(gòu)說明 Structure of CAY

1.CAY型泵為單級/兩級單吸懸臂式離心油泵，磁力驅(qū)動全密封，無泄漏。

2.殼體徑向剖分，泵安裝的支撐面在軸心線的水平面上，泵的進(jìn)出口均垂直向上。

3.泵的軸向力由葉輪上的平衡孔或葉輪對稱布置達(dá)到平衡，殘余軸向力由推力軸承來承受。

4.內(nèi)置滑動軸承的潤滑方式為工藝液體自潤滑。

5.外部軸承體外表面鑄成有散熱片，輸送介質(zhì)溫度小于120℃時(shí)，可采用空氣冷卻，溫度在120～260℃之間，可選用風(fēng)扇冷卻，溫度大于260℃時(shí)應(yīng)采用水冷卻。

6.采用膜片式加長聯(lián)軸器部件，以便于檢修。

7.從原動機(jī)端看，泵為逆時(shí)針方向旋轉(zhuǎn)。

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.
