Check that the pump body and parts have notbeen accidentally damaged or that any boltshave not been loosened in transit.3 OPERATINGPRINCIPLEA sealless magnet drive pump uses magnet torque to transmit energy from the motor to the impeller. A magnet coupling is formed using an inner, or driven magnet, attached to the impeller and an outer, or drive magnet, attached to the motor shaft. This design eliminates mechanical shaft seals or packing, since there is no direct connection between the motor shaft and the impeller. The front and rear casings, sealed with a static o-ring, form the pump or liquid end. The magnetic field is transmitted from the drive magnet through the rear casing to the driven magnet that is attached to the impeller. The combined coupling torque of the drive magnet and impeller magnet provides the driving power to theDrive MagnetDriven Magnet4 MODELGUIDEIDENTIFICATION1 2 3 4 5 6 7 81.

Handle the pump carefullyStrong impact to the pump assembly may result in damage or reduced performance.2. StartingBefore priming the pump be sure the power is turned off then proceed with filling the pumpend with water. Note, the pump must be fully primed before starting.Next close the valve on the outlet or discharge side of pump. Turn on power to the pump,when full speed is reached gradually open the discharge vale until specified flow rate isachieved.CautionOperating the pump dry (without liquid) may cause severe damage.3. StoppingWhen stopping the pump, first close the discharge valve gradually. When it is completelyclosed, turn off the power switch so that the pump stops. Never stop the pump suddenly byquickly closing a valve (i.e., solenoid or hydraulic valves).CautionQuick valve closure may cause water hammer that can cause severe damage to thepump.4. TemperatureThe pump itself may not suffer a change in performance due to temperature fluctuation.However, the liquid may change in terms of viscosity, vapor pressure, and corrosive properties.Pay special attention to changes in liquid characteristics as a result of temperature fluctuation.Liquid temperature range: 32 – 176°F (0 – 80°C)Ambient temperature range: 32 – 104°F (0 – 40°C)5. As there is a powerful magnet inside the pump unit, do not use any liquid that contains metallicsubstances such as iron, nickel, etc.6. Do not operate the pump in the following places:∙ Places exposed to rain and/or wind.∙ Places where the temperature falls below 32°F (0°C).∙ Places where corrosive gas (such as chlorine) is present.∙ Places exposed to splashing of water or fluid being pumped.∙ Places where the ambient temperature is 104°F (40°C) or above.∙ Places where explosive or combustible materials/gases are present.7. Do not operate the pump with the following liquids:∙ For the compatibility to chemical liquid or any special liquid, contact an Iwaki America sales representative.∙ Liquids that significantly swell polypropylene.∙ Paraffinic hydrocarbons such as gasoline and kerosene.∙ Halogenated hydrocarbons such as trichloroethylene and carbon tetrachloride.∙ Ether and low-grade ester∙ Slurry(For a chemical compatibility to guide contact Iwaki America customer service.)8. To prevent fire and explosions, do not place dangerous or flammable substances near thepump.9. Be sure unit is properly ground.10. If a pumped is damaged, it can be dangerous to operate. Contact factory for assistance.11. Avoid direct physical contact with the motor or pump during operation, as surface temperaturesmay be extremely high due to operating conditions.7 INSTALLATION, WIRING AND CONNECTIONS7.1 Installation1. Installation siteInstallation site must have an ambient temperature of 32-104°F (0-40°C) and a relativehumidity lower than 90%. Install the pump where maintenance and inspection work can bedone easily.2. Pump installation methodThis pump is not self-priming. It is recommended that the pump shall be installed in aposition lower than the liquid level of the suction tank by at least 12 inches (30 cm). If thisdistance is too short, air may enter the pump, causing damage.3. Direction of pump discharge portThe discharge port can be directed as desired. However, for efficient elimination of air inthe pump end, it is recommended that the discharge port be positioned in the horizontaldirection.4. Anchoring of baseThe base of the pump must be anchored firmly. The pump must not be mounted in avertical position.7.2 Piping instructions1. To minimize frictional resistance, the shortest piping possible with a minimum number ofbends should be utilized on the inlet or suction side of the pump.2. Use a corrosion-resistant vinyl hose that is rated at or above the pressure rating of thepump (see specification table).3. Hose size (for hose-barb style pumps)Select hose size in accordance with the diameter of the pump connections. As the hosetends to be crushed under the force, the use of a braided reinforced hose is recommended.Note, if the connection on the suction side is loose air may be mixed in with pumped fluid.(In the case of high temperature liquids, special attention must be paid to the selectionof a hose.)4. Hose connectionBe sure to cut the ends of the hose straight. Press the hose end firmly against the dischargeor suction port until it reaches the bottom of the port. Use a fastener (such as a hose clamp)to make the connection tight and leak free.CautionDo not over tighten the connection ports (suction and discharge) excessively asthey are made of plastic resin and are could be damaged.5. Valve installationInstall valves close to the suction and discharge ports.∙ Suction side valve:For easy liquid removal and pump maintenance∙ Discharge side valve:For adjustment of the discharge rate or head and for easy removal and pumpmaintenance.7.3 Wiring1. Prior to wiring the pump, confirm the voltage indicated on the nameplate is correct foryour installation. (Observe all local and national regulations regarding electrical work.)The connection diagram is presented on the next page.2. The pump does not have an external switch. It starts when power is supplied to the pumpwires.Wiring diagrams• (W)MD-15R, 20R, 20RX, 20RZ, 30R, 30RX and 30RZ (Single-phase capacitor run motor withthermal protector)• (W)MD-40R, 40RX, 40RZ, 55R, 70R, 70RZ, and 100R (Single-phase capacitor run motor withthermal protector)• MD-70R, 70RZ, and 100R models (3-phase motor, 220/380V)• (W)MD-70R, 70RZ, and 100R models (3-phase motor,400/440V)8 ASSEMBLY1. Place the motor on end vertically so that the shaft is pointed upward.2. Install the drive magnet on the motor shaft and position the shaft flush with the inside of themagnet. Note: On WMD models, screw the bracket to the motor first.3. Insert the rear casing into the magnet/motor bracket.4. Install the impeller and O-ring into the rear casing.5. Place the front casing over the pump, making sure that the volute casing is aligned.6. Using a hex head driver, fasten the liquid end to the bracket using six screws. Tighten in a starpattern.9 OPERATIONCaution• Before operating the pump, confirm that connections to the discharge and suction ports are secure.• Dry run operation (operation without liquid in the pump) damages the pump. Be sure to fill the pump with liquid prior to startup.• Do not operate the pump with closed, or almost entirely closed, suction and/or discharge side valve(s). A closed suction valve will cause dry-run operation.•Do not open or close the suction or discharge side valve suddenly, this may result indecoupling and damage to the pump end. (Under such circumstances, turn off the power supply immediately. When the motor stops rotating, the magnetic coupling will be reconnect automatically.)No. Operation StepNote1 Check piping, wiringand voltage. Check connections to confirm they are secure and leak-free. Check the power supply voltage by referring to the information on the nameplate.2Open and close valves. Fully open suction side valve. Fully close discharge side valve.3 Check that pumpchamber is filled with liquid. Fill pump chamber with priming liquid.Be sure suction line is completely filled, this is especially important if pump is above liquid level.4 Supply power topumpAfter steps 1 to 3 above, connect power supply to start pump.5 Adjust dischargecapacity & head to desired values.Adjust discharge side valve gradually till desired discharge capacity and head are obtained. Do not open or close valves suddenly.Note: Do not keep discharge side valve closed for more than 1 minute.Note: Check that pump is operating normally. If not, turn off power immediately and eliminate cause referring to 'Causes of Trouble and Troubleshooting' section (p.27).6 Checkpoints during operation Be careful to prevent solids from entering the pump. Solids in thepump may cause impeller to be locked stopping liquid circulation. The motor continues to rotate even if impeller is locked. In such acase, turn off power supply at once.Pump Stopping ProcedureStep Description No. Stopping1 Close discharge side valve. Close discharge side valve gradually.Do not use electromagnetic valve for quick closing.2 Switch power off. Check that motor stops smoothly after power supply isdisconnected. If not, pump should be inspected. (For details,contact Iwaki or your dealer.)How to store pump when it is out of use for a long timeRemove the liquid from the pump if it is to be stored for a long period of time. In addition, run it with water for about 5 minutes every 3 months to prevent rust on the motor bearing.Warning• Before draining the pump, turn off the power supply.• Be sure to wear proper safety gear (gloves, protective shoes, etc.) when handling pump end for draining purposes, especially when a hazardous chemical is being pumped.CautionNote that residual liquid may run from the discharge and suction ports when the housing isremoved. Do not allow any electric parts to come in contact with the liquid.Never discharge hazardous or chemical liquid over the ground or floor in the plant. Instead, use a draining pan (or container). Observe each applicable local law or regulation for the handling or disposal of hazardous liquids.Draining procedure1. Turn off the power supply. (Make sure no other operator will turn the power supply onaccidentally.)2. Close the discharge and suction sides valves fully.3. Remove the hoses piping attached to the pump.4. Remove the screws on the pump base to detach the pump from its mounting location.5. Rotate the pump.6. Discharge hazardous liquids appropriately.10 MAINTENANCE/INSPECTIONMaintenance and inspection• When the pump has been used for a long time, the front casing screws attaching the pump headto the motor bracket may loosen.

磁力泵工作原理
磁力泵工作原理磁力泵是一种无轴封、无泄漏的离心泵，其工作原理基于磁力耦合技术。
磁力泵由电机、磁力耦合器、泵体和叶轮组成。
其主要工作原理如下：1. 电机驱动：磁力泵的电机通过旋转产生动力，将能量传递给磁力耦合器。
2. 磁力耦合器：磁力耦合器由外磁铁和内磁铁组成。
外磁铁连接到电机轴上，内磁铁连接到泵轴上。
当电机轴旋转时，外磁铁的磁场会通过泵体中的隔离壁传递给内磁铁，从而实现无接触的能量传递。
3. 泵体和叶轮：泵体是磁力泵的主体部分，通常由不锈钢等材料制成。
泵体内部有一个叶轮，叶轮通过磁力耦合器与电机轴相连。
当电机轴旋转时，磁力耦合器的磁场会驱动叶轮旋转。
4. 磁力传递：磁力耦合器通过磁力传递将电机轴的动力传递给泵轴，使叶轮在泵体内旋转。
由于磁力耦合器的存在，泵体和叶轮与外界完全隔离，避免了泄漏的风险。
5. 吸入和排出：当叶轮旋转时，泵体内的液体被吸入叶轮中心，然后被离心力推向泵体的出口。
这样，磁力泵就能够将液体从低压区域输送到高压区域，实现流体的输送功能。
磁力泵的工作原理使其具有以下优点：1. 无泄漏：由于磁力泵没有轴封，液体无法通过泵体进入外界，从而避免了泄漏的风险。
这使得磁力泵非常适用于处理有毒、腐蚀、易燃和易爆等危险介质。
2. 无接触：磁力泵通过磁力耦合器实现能量传递，泵体和叶轮与外界完全隔离，无需轴封。
这种无接触的设计减少了泵的磨损和维护成本。
3. 节能环保：磁力泵的无泄漏设计减少了能源的浪费，同时也减少了对环境的污染。
此外，磁力泵通常采用高效电机，具有较低的能耗。
4. 高可靠性：磁力泵的无轴封设计减少了泵的故障点，提高了泵的可靠性和使用寿命。
同时，由于泵体和叶轮之间没有接触，磁力泵能够处理高温、高粘度和含固体颗粒的介质。
需要注意的是，磁力泵也有一些限制和注意事项：1. 温度限制：磁力泵的磁力耦合器通常由永磁材料制成，对温度敏感。
因此，在使用磁力泵时，需要注意介质的温度是否在磁力耦合器的工作温度范围内。

md泵
长沙自平衡多级泵厂家宏力水泵整理 MD泵概述：MD泵供输送清水及物理化学性质类似于水的液体之用。
该泵扬程为H：134米，流量Q：155m3/h。
液体的最高温度不得超过80℃，广泛应用于矿山排水、工厂及城市给水之用。
使用温度T：80℃+80℃。
MD泵产品结构说明MD泵为多级分段式，其吸入口位于进水段上，成水平方向，吐出口在水段上垂直向上，其扬程可根据使用需要而增减水泵级数。
多级离心泵装配良好与否，对性能影响关系很大，尤其是各个叶轮的口出与导翼的进出中心，其中稍有偏差即将使水泵的流量减少，扬程降低效率差，故在检修装配时务必注意。
MD泵主要零件有:进水段、中段、出水段、叶轮、导翼挡板、出水段导翼、轴、密封环、平衡环、轴套、尾盖及轴承体。
进水段、中段、导叶挡板、出水段导翼、出水段及尾盖均为铸铁制成，共同形成泵的工作室。
叶轮为优质铸铁制成，内有叶片，液体沿轴向单侧进入，由于叶轮前后受压不等，必然存在轴向力，此轴向力由平衡盘来承担，叶轮制造时经静平衡试验。
轴为优质炭素钢制成，中间装有叶轮，用键、轴套及轴套螺母固定在轴上。
轴的一端装联轴器部件，与电机直接连接。
密封环为铸铁制成，防止水泵高压水漏回进水部分，分别固定在进水段与中段之上，为易损件，磨损后可用备件更换。
平衡环为铸铁制成，固定在出水段上，它与平衡共同组成平衡装置。
平衡盘为耐磨铸铁制成，装在轴上，位于出水段与尾盖之间，平衡轴向力。
轴套为铸铁制成，位于填料室处，作固定叶轮和保护泵轴入用，为易损件，磨损后可用备件更换。
轴承是单列向心球轴承，采用钙基润滑脂润滑。
填料起密封作用，防止空气进入和大量液体漏出，填料密封由进水段和尾盖上的填料室，填料压盖，填料环及填料等组成，少量高压水流入填料室中起水封作用。
填料的松紧程度必须适当，不可太紧亦不可太松，以液体能一滴一滴的渗出为准。
如果填料太紧，轴套容易发热，同时耗费功率。
填料太松，由于液体流失要降低水泵的效率。

磁力泵简介
磁力泵工作原理及结构是什么？
磁力泵工作原理及结构是什么？
磁力泵由泵、磁力传动器、电动机三部分组成。
关键部件磁力传动器由外磁转子、内
磁转子及不导磁的隔离套组成。
当电动机带动外磁转子旋转时，磁场能穿透空气隙和非磁性物质，带动与叶轮相连的内磁转子作同步旋转，实现动力的无接触传递，将动密封转化为静密封。
由于泵轴、内磁转子被泵体、隔离套完全封闭，从而彻底解决了“跑、冒、滴、漏”问题，消除了炼油化工行业易燃、易爆、有毒、有害介质通过泵密封泄漏的安全隐患，有力地保证了职工的身心健康和安全生产。
一、磁力泵工作原理
将n对磁体（n为偶数）按规律排列组装在磁力传动器的内、外磁转子上，使磁体部分相互组成完整藕合的磁力系统。
当内、外两磁极处于异极相对，即两个磁极间的位移角Φ＝0，此时磁系统的磁能最低；当磁极转动到同极相对，即两个磁极间的位移角Φ＝2π/n，此时磁系统的磁能最大。
去掉外力后，由于磁系统的磁极相互排斥，磁力将使磁体恢复到磁能最低的状态。
于是磁体产生运动，带动磁转子旋转。
二、结构特点
1．永磁体
由稀土永磁材料制成的永磁体工作温度范围广(-45－400℃)，矫顽力高，磁场方向具有很好的各向异性，在同极相接近时也不会发生退磁现象，是一种很好的磁场源。
2.隔离套
磁力泵在采用FRPP隔离套时，隔离套处于一个正弦交变的磁场中，在垂直于磁力线方向的截面上感应出涡电流并转化成热量。
涡流的表达式为：。
其中Pe－涡流；K—常数；n—泵的额定转速；T－磁传动力矩；F－隔套内的压力；D－隔套内径；一材料的电阻率；—材料的抗拉强度。
当泵设计好后，n、T是工况给定的，要降低涡流只能从F、D、、等方面考虑。
选用高电阻率、高强度的非金属材料制作隔离套，在降低涡流方面效果十分明显。
3．冷却润滑液流量的控制
磁力泵泵运转时，必须用少量的液体对内磁转子与隔离套之间的环隙区域和滑动轴承的摩擦副进行冲洗冷却。
冷却液的流量通常为泵设计流量的2%-3%，内磁转子与隔离套之间的环隙区域由于涡流而产生高热量。
当冷却润滑液不够或冲洗孔不畅、堵塞时，将导致介质温度高于永磁体的工作温度，使内磁转子逐步失去磁性，使磁力传动器失效。
当介质为水或水基液时，可使环隙区域的温升维持在3-5℃；当介质为烃或油时，可使环隙区域的温升维持在5-8℃。
4．滑动轴承
磁力泵滑动轴承的材料有浸渍石墨、填充聚四氟乙烯、工程陶瓷等。
由于工程陶瓷具有很好的耐热、耐腐蚀、耐摩擦性能，所以不锈钢磁力泵的滑动轴承多采用工程陶瓷制作。
由于工程陶瓷很脆且膨胀系数小，所以轴承间隙不得过小，以免发生抱轴事故。
由于磁力泵的滑动轴承以所输送的介质进行润滑，所以应根据不同的介质及使用工况，选用不同的材质制作轴承。
5．保护措施
当磁力传动器的从动部件在过载情况下运行或转子卡死时，磁力传动器的主、从动部件会自动滑脱，保护机泵。
此时磁力传动器上的永磁体在主动转子交变磁场的作用下，将产生涡损、磁损，造成永磁体温度升高，磁力传动器滑脱失效。
三、磁力泵的优点
同使用机械密封或填料密封的离心泵相比较，磁力泵具有以下优点。
1．泵轴由动密封变成封闭式静密封，彻底避免了介质泄漏。
2．无需独立润滑和冷却水，降低了能耗。
3．由联轴器传动变成同步拖动，不存在接触和摩擦。
功耗小、效率高，且具有阻尼减振作用，减少了电动机振动对泵的影响和泵发生气蚀振动时对电动机的影响。
4．过载时，内、外磁转子相对滑脱，对电机、泵有保护作用。
四、运行注意事项
1．防止颗粒进入
(1)不允许有铁磁杂质、颗粒进入磁力传动器和轴承摩擦副。
(2)输送易结晶或沉淀的介质后要及时冲洗（停泵后向泵腔内灌注清水，运转1min后排放干净），以保障滑动轴承的
使用寿命。
(3)输送含有固体颗粒的介质时，应在泵流管入口处过滤。
2．防止退磁
(1)磁力矩不可设计得过小。
(2)应在规定温度条件下运行，严禁介质温度超标。
可在磁力泵隔离套外表面装设铂电阻温度传感器检测环隙区域的温升，以便温度超限时报警或停机。
3．防止干摩擦
(1）严禁空转。
(2）严禁介质抽空。
