进口离心油泵/Centrifugal oil pump/德国品质
德国KAYSEN凯森进口离心油泵概述
离心油泵的主要过流部件有吸水室、叶轮和压水室。通过改变泵过流部件材质、密封形式和增加冷却系统用于输送热水、油类、腐蚀性或含磨粒的介质。
主要特点：
●叶轮是离心泵的核心部分，它转速高输出力大，叶轮上的叶片又起到主要作用，叶轮在装配前要通过静平衡实验。叶轮上的内外表面要求光滑，以减少水流的摩擦损失。
●泵体也称泵壳，它是水泵的主体。起到支撑固定作用，并与安装轴承的托架相连接。
●泵轴的作用是借联轴器和电动机相连接，将电动机的转距传给叶轮，所以它是传递机械能的主要部件。
●轴承是套在泵轴上支撑泵轴的构件，有滚动轴承和滑动轴承两种。滚动轴承使用牛油作为润滑剂加油要适当一般为2/3～3/4的体积太多会发热，太少又有响声并发热！滑动轴承离心泵结构使用的是透明油作润滑剂的，加油到油位线。太多油要沿泵轴渗出并且漂*，太少轴承又要过热烧坏造成事故！在水泵运行过程中轴承的温度***高在85度一般运行在60度左右，如果高了就要查找原因（是否有杂质，油质是否发黑，是否进水）并及时处理！
●密封环又称减漏环。叶轮进口与泵壳间的间隙过大会造成泵内高压区的水经此间隙流向低压区，影响泵的出水量，效率降低！间隙过小会造成叶轮与泵壳摩擦产生磨损。为了增加回流阻力减少内漏，延缓叶轮和泵壳的所使用寿命，在泵壳内缘和叶轮外援结合处装有密封环，密封的间隙保持在0.25～1.10mm之间为宜。
●填料函主要由填料，水封环，填料筒，填料压盖，水封管组成。填料函的作用主要是为了封闭泵壳与泵轴之间的空隙，不让泵内的水流不流到外面来也不让外面的空气进入到泵内。始终保持水泵内的真空！当泵轴与填料摩擦产生热量就要靠水封管住水到水封圈内使填料冷却。保持水泵的正常运行。所以在水泵的运行巡回检查过程中对填料函的检查是特别要注意！在运行600个小时左右就要对填料进行更换。
主要优点：
●水力模型***，效率高，性能范围广
●泵运行平稳，噪音低
●轴为全封结构，确保了不与介质接触，不锈蚀，使用寿命长
●轴封采用软填料密封或机械密封，密封安全可靠、结构简单，维修方便快捷
主要应用：
●工业
●油管道
●轮船
●远距离供油
●码头配套
Germany KAYSEN imported centrifugal oil pump overview
The main flow components of the centrifugal oil pump include a suction chamber, an impeller and a pressurized water chamber. By changing the material of the pump's flow-through components, the form of the seal, and adding a cooling system for transporting hot water, oil, corrosive or abrasive-containing media.
main feature:
●The impeller is the core part of the centrifugal pump. It has high output speed and large output force. The blade on the impeller plays a major role. The impeller should pass the static balance test before assembly. The inner and outer surfaces of the impeller are required to be ***ooth to reduce the frictional loss of water flow.
● The pump body is also called the pump casing, which is the main body of the pump. It acts as a support and is attached to the bracket on which the bearing is mounted.
● The function of the pump shaft is to connect the coupling to the motor and tran***it the torque of the motor to the impeller, so it is the main component that tran***its mechanical energy.
●The bearing is a member that supports the pump shaft on the pump shaft, and has two kinds of rolling bearings and sliding bearings. Rolling bearings use butter as a lubricant to refuel properly. Generally 2/3 ~ 3 / 4 of the volume will be too much heat, too little and there is noise and fever! The sliding bearing centrifugal pump structure uses a transparent oil as a lubricant and is refueled to the oil level line. Too much oil will ooze along the pump shaft and float *, too few bearings will overheat and burn out! During the operation of the pump, the temperature of the bearing is at most 85 degrees and generally runs at about 60 degrees. If it is high, it is necessary to find the cause (whether there are impurities, whether the oil is black or not, whether it is water) and deal with it in time!
● The sealing ring is also called the leak reducing ring. The gap between the impeller inlet and the pump casing is too large, so that the water in the high pressure zone of the pump flows to the low pressure zone through the gap, which affects the water output of the pump and reduces the efficiency! Too ***all a gap will cause friction between the impeller and the pump casing. In order to increase the backflow resistance and reduce the internal leakage, and delay the service life of the impeller and the pump casing, a sealing ring is arranged at the inner edge of the pump casing and the outer joint of the impeller, and the sealing gap is preferably maintained between 0.25 and 1.10 mm.
●The stuffing box is mainly composed of packing, water sealing ring, packing tube, packing gland and water sealing tube. The function of the stuffing box is mainly to close the gap between the pump casing and the pump shaft, so that the water in the pump does not flow to the outside and the outside air does not enter the pump. Always keep the vacuum inside the pump! When the pump shaft and the packing friction generate heat, the water seals the water to the water seal ring to cool the packing. Keep the pump running properly. Therefore, it is especially important to check the stuffing box during the running inspection of the pump! The packing should be replaced after about 600 hours of operation.
The main advantage:
●Advanced hydraulic model, high efficiency and wide performance range
●The pump runs ***oothly and the noise is low.
●The shaft is a full-sealed structure, ensuring no contact with the medium, no corrosion, long service life
●The shaft seal is sealed with soft packing or mechanical seal. The seal is safe and reliable, the structure is simple, and the maintenance is convenient and quick.
main application:
●Industry
● oil pipeline
●ship
●Long distance oil supply
●Wharf support
