主要应用：
自吸式离心油泵适用于石油行业、陆地油库、油罐车的理想产品，并适合于作船用货油泵、舱底泵、消防泵和压载泵及机器冷却水循环等，分别输送***、煤油、柴油、航煤等石油产品和海水、清水，介质温度-20℃-80℃，如输送化工液体可改用耐腐蚀机械密封。
自吸油泵拆装维修：
该泵的特点是结构简单可靠，经久耐用。在泵正常情况下，一般不需要经常拆开***。当发现故障后随时给予排除即可。
1．维护该泵时应注意几个主要部位。
A．滚动轴承：当油泵长期运行后，轴承磨损到一定程度时，须进行更换。
B．前密封环、后密封环：当密封环磨损到一定程度时，须进行更换。
C． 机械密封：机械密封在不漏油的情况下，一般不应拆开检查。若轴承体下端泄漏口处产生严重泄漏时，则应对机械密封进行拆检。装拆机械密封时，必须轻取轻放， 注意配合面的清洁，保护好静环和动环的镜面，严禁敲击碰撞。因机械密封而产生泄漏的原因主要是摩擦付镜面拉毛所至。其修复办法，可对磨擦付端面进行研磨使 ***镜面。机械密封产生泄漏的另一原因是“o”形橡胶密封圈(或缓冲垫)安装不当、或者变形老化所至。此时则需调整或更换“O”形密封圈进行重新装配。
2．油泵拆装顺序：
A．拆下电动机或脱出联轴器。
B．拆出轴承体总成，检查叶轮和前口环的径向间隙，检查叶轮螺母有无松动。
C．拆下叶轮螺母，拉出叶轮，检查叶轮和后密封环的径向间隙。
D．松出机械密封的紧定螺钉，拉出机械密封的动环部分，检查动、静环端面的贴合情况，检查“o”形密封圈(或缓
冲垫)的密封情况。
E．旋出联轴器的紧定螺母，拉出联轴器。
F．拆下轴承端盖，拆出泵轴和轴承。
G．安装时以相反顺序进行装配即可。

main application:
Self-priming centrifugal oil pump is suitable for oil industry, land oil storage tank and oil tank truck. It is suitable for marine cargo oil pump, bilge pump, fire pump and ballast pump and machine cooling water circulation. It transports gasoline and kerosene respectively. Diesel, jet fuel and other petroleum products and seawater, clean water, medium temperature -20 ° C -80 ° C, such as transport chemical liquid can be changed to corrosion-resistant mechanical seal.
Self-priming pump disassembly and repair:
The pump is characterized by simple and reliable structure and durability. Under normal conditi*** of the pump, it is generally not necessary to open the maintenance frequently. When you find a fault, you can always give it out.
1. There are several main points to be aware of when servicing the pump.
A. Rolling bearings: When the oil pump is used for a long time, the bearing must be replaced when it wears to a certain extent.
B. Front seal ring, rear seal ring: When the seal ring wears to a certain extent, it must be replaced.
C. Mechanical seal: Mechanical seals should not be opened for inspection without oil leakage. If a serious leak occurs at the lower end of the bearing body, the mechanical seal should be disassembled. When assembling and disassembling the mechanical seal, it must be taken lightly and gently. Pay attention to the cleaning of the mating surface, protect the mirror surface of the static ring and the moving ring, and do not strike the collision. The reason for the leakage due to the mechanical seal is mainly due to the friction of the mirror surface. The repair method can grind the end face of the friction to restore the mirror surface. Another cause of leakage from mechanical seals is the improper installation of “o” rubber seals (or cushi***) or aging. At this point, the O-ring seal needs to be adjusted or replaced for reassembly.
2. Oil pump disassembly sequence:
A. Remove the motor or take off the coupling.
B. Remove the bearing body assembly, check the radial clearance between the impeller and the front ring, and check the impeller nut for looseness.
C. Remove the impeller nut, pull out the impeller, and check the radial clearance between the impeller and the rear seal ring.
D. Loosen the set screw of the mechanical seal, pull out the moving ring part of the mechanical seal, check the fit of the moving and static ring end faces, and check the “o” shaped seal ring (or slow down)
Sealing of the pad).
E. Unscrew the tightening nut of the coupling and pull out the coupling.
F. Remove the bearing end cap and remove the pump shaft and bearing.
G. It can be assembled in reverse order during installation.
