进口化工泵（化工泵 品牌）

KAYSEN凯森化工泵概述
化工泵是节能泵的一种，泵的性能，技术要求，根据国际标准ISO2858所规定的性能和尺寸设计的，化工泵是单级单吸(轴向吸入)耐腐蚀离心泵，供输送不含固体颗粒、具有腐蚀性、粘度类似水的液体化工泵分类：不锈钢化工泵，塑料化工泵，氟塑料化工泵，电动化工泵，气动化工泵。

主要特点：
负压泵
开泵前，吸入管和泵内必须充满液体。开泵后，叶轮高速旋转，其中的液体随着叶片一起旋转，在离心力的作用下，飞离叶轮向外射出，射出的液体在泵壳扩散室内速度逐渐变慢，压力逐渐增加，然后从泵出口，排出管流出。此时，在叶片中心处由于液体被甩向周围而形成既没有空气又没有液体的真空低压区，液池中的液体在池面大气压的作用下，经吸入管流入泵内，液体就是这样连续不断地从液池中被抽吸上来又连续不断地从排出管流出。
正压泵
主要指液下泵其工作原理以加油站潜油泵 和长轴液下泵为例，潜油泵是将电机和泵一起浸入罐底，电机带动叶轮增压将介质推送到地面目标，长轴液下泵是将泵和电机分开用长轴连接，其工作原理是正压输送介质，因此解决了负压输送介质时产生的气阻问题和叶轮的汽蚀问题。潜油泵的电机不在液面上，而是在液面下。电机是潜没电机，与泵轮连接成一体潜在液体里，这样设计的主要优点是：泵的轴承只有几百毫米，没有长轴，不会出现摆动问题，运行平稳，声音很小，几乎没有磨损。
化工泵密封形式主要有：油封密封、垫片密封、螺纹密封、迷宫密封、填料密封和动力密封、机械密封。
油封密封
是一种自紧式唇状密封，其结构简单，尺寸小，成本低廉，维护方便，阻转矩较小，既能防止介质泄漏，也能防止外部尘土和其它有害物质侵入，而且对磨损有一定的补偿能力，但不耐高压，所以一般用在低压场合的化工泵上。
垫片密封
垫片是离心泵静密封的基本元件，使用范围非常广泛。垫片的选型主要根据化工泵输送介质、温度、压力和腐蚀性等因素决定。
螺纹密封
在化工泵上一般有两种形式，一种是螺纹联接垫片密封，一种是螺纹加填充济密封，二者皆用于小直径螺纹连接的密封场合。螺纹联电动隔膜泵接垫片密封的密封件是垫片，而螺纹只起提供压紧力的作用。
迷宫密封
在设计合理，加工精良，装配完好、转速较高时，迷宫密封效果很好。但在实际应用中，因此而产生的化工泵泄漏却很多，所以在化工泵密封中不常用。
填料密封
是将富有压缩性和回弹性的填料放入填料函内，依靠压盖的轴向压紧力转化为径向密封力，从而起到密封作用。
这种密封方法称为填料密封，这种填料称为密封填料。由于填料密封结构形式简单，更换方便、价格低廉、适应转速、压力、介质宽泛而在化工泵的设计中得到普遍采用。
动力密封
化工泵在与运转时，副叶轮所产生的压头平衡了主叶轮出口高压液体，从而实现密封。停车时，副叶轮不起作用，因此必须同时配备停车密封装置解决停车时可能产生的化工泵泄漏。
副叶轮密封结构简单、密封可靠、使用寿命长，化工泵运转中可实现滴水不漏，因此在化工泵输送含杂质介质的泵上经常采用。
机械密封
现在化工泵行业使用最为广泛的密封形式，由于机械密封具有泄漏量少和寿命长等优点，所以当今 上机械密封是在这些设备最主要的轴密封方式。机械密封又叫端面密封，在国家有关标准中是这样定义的：“由至少一对垂直于旋转轴线的端面在流体压力和补偿机构弹力（或磁力）的作用以及辅助密封的配合下保持贴合并相对滑动而构成的防止流体泄漏的装置。”

主要优点：
●检修方便
●全系列水利性能布局合理
●用户选择范围宽
●“后开式”结构
●效率和吸程达到国际先进水平

Germany Kaysen imported chemical pump overview

The chemical pump is a kind of energy-saving pump. The performance and technical requirements of the pump are designed according to the performance and size specified in the international standard ISO2858. The chemical pump is a single-stage single-suction (axial suction) corrosion-resistant centrifugal pump for transportation. Solid chemical, liquid chemical pump with corrosive and viscosity-like water classification: stainless steel chemical pump, plastic chemical pump, fluorine plastic chemical pump, electric chemical pump, pneumatic chemical pump.

main feature:

Negative pressure pump

The suction tube and pump must be filled with liquid before the pump is turned on. After the pump is turned on, the impeller rotates at a high speed, and the liquid rotates with the blade. Under the action of the centrifugal force, it flies outward from the impeller, and the liquid that is ejected in the pump chamber diffuses slowly, the pressure gradually increases, and then the pump At the exit, the discharge pipe flows out. At this time, at the center of the blade, the liquid is drawn to the surroundings to form a vacuum low-pressure zone with neither air nor liquid. The liquid in the liquid pool flows into the pump through the suction pipe under the action of the atmospheric pressure of the pool surface, and the liquid is continuously continuous. It is continuously sucked from the liquid pool and continuously flows out from the discharge pipe.

Positive pressure pump

Mainly refers to the working principle of the submerged pump. The submersible pump and the long shaft submerged pump are used as an example. The submersible pump immerses the motor and the pump together in the bottom of the tank. The motor drives the impeller to push the medium to the ground target, and the long shaft liquid The pump connects the pump and the motor separately with a long shaft. The working principle is that the medium is transported under positive pressure, thus solving the problem of air resistance generated by the negative pressure conveying medium and the cavitation problem of the impeller. The motor of the submersible pump is not on the liquid surface, but under the liquid surface. The motor is a submersible motor and is connected to the pump wheel into a potential liquid. The main advantage of this design is that the bearing of the pump is only a few hundred millimeters, there is no long axis, there is no swing problem, the operation is stable, the sound is very small, almost no abrasion.

The chemical pump seal forms mainly include: oil seal seal, gasket seal, thread seal, labyrinth seal, packing seal and dynamic seal, mechanical seal.

Oil seal

The utility model relates to a self-tightening lip seal, which has the advantages of simple structure, small size, low cost, convenient maintenance and small resistance torque, which can prevent medium leakage, prevent external dust and other harmful substances from invading, and has wear resistance. A certain compensation capacity, but not high pressure, so it is generally used in chemical pumps on low pressure occasions.

Gasket seal

The gasket is the basic component of the centrifugal pump static seal and is used in a wide range of applications. The selection of gaskets is mainly determined by factors such as the transport medium, temperature, pressure and corrosivity of the chemical pump.

Thread seal

There are generally two forms on chemical pumps, one is a threaded joint gasket seal, and the other is a threaded and filled seal, both of which are used for sealing of small diameter threaded joints. The seal of the threaded electric diaphragm pump gasket is a gasket, and the thread only serves to provide a pressing force.

Labyrinth seal

The maze sealing effect is very good when the design is reasonable, the processing is excellent, the assembly is good, and the rotation speed is high. However, in practical applications, the resulting chemical pump leaks are numerous, so it is not commonly used in chemical pump seals.

Packing seal

The filler with compressibility and resilience is placed in the stuffing box, and the axial pressing force of the gland is converted into a radial sealing force, thereby sealing.

This method of sealing is called a packing seal and this packing is called a packing. Because the packing sealing structure is simple in form, convenient to replace, low in price, suitable for speed, pressure and wide medium, it is widely used in the design of chemical pumps.

Dynamic seal

When the chemical pump is in operation, the indenter generated by the auxiliary impeller balances the high pressure liquid at the outlet of the main impeller to achieve sealing. When parking, the auxiliary impeller does not work, so it must be equipped with a parking seal to solve the chemical pump leakage that may occur when parking.

The auxiliary impeller has a simple sealing structure, reliable sealing and long service life. The drip water can be prevented from leaking during the operation of the chemical pump, so it is often used in the pump of the chemical pump to transport the impurity-containing medium.

Machinery Seal

Nowadays, the chemical pump industry is the most widely used sealing form. Because mechanical seals have the advantages of less leakage and long life, mechanical seals in the world are the most important shaft sealing methods in these devices. Mechanical seals, also known as end seals, are defined in the relevant national standards: "The at least one pair of end faces perpendicular to the axis of rotation are held together by the action of the fluid pressure and the compensating mechanism's spring force (or magnetic force) and the auxiliary seal. a device that prevents fluid leakage by sliding relative to each other."

The main advantage:

● easy to repair

●The whole series of water conservancy performance layout is reasonable

●User selection range is wide

● "Back open" structure

● Efficiency and suction reach international advanced level
