一、概述

I. Overview

CQL型磁力泵是我公司针对含有一定固体颗粒和易气化介质而研制开发的一种新型立式单级单吸泥浆型磁力驱动离心泵, 该型泵具有全密封、无泄漏、无污染、抗磨损、耐腐蚀能力强、安全可靠、使用寿命长等特点,适用于含有杂质颗粒、易气化、具有腐蚀性、易燃易爆及有毒介质的输送,可广泛应用于石油化工、精细化工、冶金、电力等行业。

CQL magnetic driven pump is a new type of vertical single-stage single-suction sludge type magnetic driven centrifugal pump developed by our company specifically for medium containing certain solid particles and medium liable to gasification. This pump features in full-enclosure, non-leakage, non-pollution, strong wear resistance, strong corrosion resistance, safety and reliability, and long life. It is applicable for conveying medium which is containing impurity particles, liable to gasification, corrosive, flammable and explosive, or toxic, and widely used in such fields as petrochemical industry, fine chemical industry, metallurgy, and electric power, etc.

CQL型泵通过内外磁转子进行耦合传动,外磁转子与电机直联,隔离套将内磁转子密封在泵腔内,实现磁力密封,从而实现全密封。

CQL pump achieves the coupling transmission through the inner and outer magnetic rotors, outer magnetic rotor directly connected with the motor, the isolation sleeve sealing the internal magnetic rotor in the pump cavity, thus realizing the magnetic seal, and the full enclosure in the end as well.

该型泵从根本上解决了磁力泵输送含固体颗粒的问题,适于输送固体颗粒浓度不超过30%的液体,是一种典型的可输送含固体颗粒物的磁力泵。

This pump has fundamentally solved the problem of the magnetic driven pump conveying medium containing solid particles, suitable for conveying liquid with solid particle concentration no more than 30%, and it is a typical magnetic driven pump able to conveying medium containing solid particles.

四、结构说明
IV. Description of structure

CQL型泵是一种立式结构泵,泵由底座、泵体、泵盖,轴承体、支架、叶轮、轴、滑动轴承组件、循环叶轮、支架和磁驱部件等零部件组成。 泵最下端是底座,底座上面是泵体,泵进口位于泵体下侧,泵出口在泵体的另一侧。 叶轮安装在泵轴下端,由叶轮螺母固定。 磁驱部件外磁转子安装于电机轴上,内磁转子安装于泵轴的上端。

CQL pump is a vertical pump, composed of the pump base, pump body, pump cover, bearing body, bracket, impeller, shaft, sliding bearing components, circulation impeller, bracket and the magnetic drive components. Pump base is located at the bottom, the pump body above the base, the pump inlet at the lower position of the pump body, and the pump outlet on the other side. The impeller is mounted at the lower end of pump shaft, and fixed by the impeller nuts. The outer magnetic rotor of the magnetic drive components is mounted on the motor shaft, and the inner magnetic rotor on the top of the pump shaft.

CQL泵有多种结构形式,根据含固量的不同,可采用水力旋液分离技术、气体阻隔密封、磁力密封与机械密封组合结构等。

CQL pump is of a variety of structural forms; depending on the different solid contents, the hydraulic liquid separation technology, gases trap seal, magnetic seal and mechanic seal combination structure, etc. can be applied.

在泵腔内可利用水力旋液分离技术,将固体颗粒分离,以防止或减轻固体颗粒物对隔离套、轴承磁转子的损坏使泵能够在含固体颗粒的介质中正常运行。

In the pump cavity, the hydraulic liquid cyolonic separation technology can be applied for separating the solid particles, in order to prevent or reduce the damage incurred by solid particles upon isolation sleeve, bearing and magnetic rotor, so that the pump can run normally in the medium containing solid particles.

对固体颗粒浓度高的物料输送,CQL可采用组合密封结构,在磁力密封基础上增加气体阻隔密封或者机械密封,并辅以动力密封设计,防止介质对轴承以及磁转子造成腐蚀和磨损

To convey material with high concentrations of solids, CQL pump can also adopt the combination sealing structure; on the basis of the magnetic seal, add the gas trap seal or mechanical seal, which is supplemented by dynamic seal design, so as to prevent the medium corrosion and wear on bearings and magnetic rotor.

该型泵的结构有以下特点:

The pump structure has the following features:

1.立式、磁力驱动,轴向吸入,径向排出,占地面积小。

1. The pump is of vertical structure, magnetic drive, axial suction, radial discharge, and small covering area.

2.通过磁性联轴器驱动,运行安全可靠。

2. It is driven by the magnetic coupling drive, ensuring safe and reliable operation.

3.轴向力由副叶片平衡,残余轴向力由滑动轴承组件的推力片承受。 除平衡轴向力之外,副叶片还可以降低颗粒物对叶轮背面以及泵盖的磨损,使运行更为可靠。

3. The axial force is balanced by back blades and the residual axial force is on the thrust blades of the sliding bearing component. In addition to balancing the axial force, the back blades can also reduce the wear incurred by particles upon impeller back and the pump cover, and make the operation more reliable.

4.优化的叶轮水力设计,叶轮适用于含杂质、含固体颗粒的物料输送。

4. The optimized impeller hydraulic design makes the impeller is suitable for conveying material containing impurities and solid particles.

5、叶轮水力设计配套动力密封运行,把物料气相引入到叶轮背部,气相平衡防止了汽蚀破坏,让整个泵组件在边界条件下都是安全的。

5. In the impeller hydraulic design complete with the dynamic sealing, the material gas is introduced into the back of the impeller, where the gas phase balance has prevented the cavitation damage, so that the whole pump components under the boundary conditions are safe.

6.采用自润滑结构,润滑简单可靠。

6. The structure of self-lubricating is applied, in which the lubrication is simple and reliable.

7、隔离套材料的合理选用消除了磁涡流损失,磁传动效率高。

7. The reasonable selection of isolation sleeve materials has eliminated magnetic eddy current loss, and increased the magnetic transmission efficiency.

8.泵入口处于系统的最低位,能够方便迅速的排除泵内积液。

8. Pump inlet is located at the lowest level in the system, so that fluid inside the pump can be discharged in a convenient and quick manner.

9.立式结构,有利于排气,适宜对泵腔进行清洗、吹扫处理。

9. The vertical structure is conductive for exhausting and suitable for cleaning and purging the pump cavity.

10.泵及电机由底座支撑,底座用地脚螺栓固定在地面,整体结构简单可靠,安装检修方便。

10. The pump and motor is supported by the base, and the base is fixed on the ground, so the overall structure is simple and reliable, facilitating installation and maintenance.

11、对于气体阻隔密封的泵,为了使密封气体压力和流量能有效地控制在合理的范围内,泵需配带气体稳压控制仪表,将减压阀、压力开关、流量计、压力表及单向阀等仪表集于一体,简单方便而快捷的对密封气体进行有效控制。

11. For the gas seal pump, in order to make the seal gas pressure and flow rate effectively controlled in a reasonable range, the pump should be installed with gas regulator control instrument, and the pressure reducing valve, pressure switch, flow meter, pressure gauge and check valve are integrated, achieving the effective control on the seal gas in a simple and convenient and fast way.
