Section:L and J FRAME PUMPSPage: 1Date: December 1, 1997 OPERATION – ASSEMBLY INSTRUCTIONS AND PARTS LIST FOR“L2” DRIVE END(FRAME SIZES 1L2, 2L2, 3L2, 2M1, 3M1, 6M1)GENERALThe Moyno® Pump is one of the most versatile pumps available. It has been proven in thou-sands of applications over the past 50 years. It is backed by the experience gained over these years, both in application and manufacturing expertise.The Moyno progressing cavity pump is a single-screw rotary pump. The pumping action is created by the single helical rotor rolling eccentrically in the double threaded helix of the stator. In its revolution, the rotor forms in conjunction with the stator a series of sealed cavities 180 degrees apart. As the rotor turns, the cavities progress from the suction to the discharge. As one cavity diminishes, the opposing cavity is increasing at exactly the same rate. Thus, the sum of the two discharges is a constant volume. The result is a pulsation-less positive displacement flow with no valves.NAMEPLATE DATAThe Moyno Pump nameplate, located on the bearing housing, carries the serial number, frame size, and type designation. All are extremely important and must be used when ordering spare parts.Record the nameplate data of your pump in the spaces provided in the heading of Page 112.Moyno Pumps are identified by Frame and Type. Pump Frame is essentially an indication of size. It consists of a number, a letter, and a number (i.e. 2L2). The first number indicates the number of stages in the pumping elements. The letter indicates the model. The final number indicates the size of the rotor-stator pumping elements. A frame 2L2 pump, therefore, has two stages of size 2 pumping elements.The “L” in the frame size indicates a standard relationship between the housing, bearings, and drive shaft and the size of the pumping elements. Many variations may be made by adapting smaller element sizes to a larger drive end size. This may be necessary due to the severity of a specific pumping application. In cases where the drive end (housing, bearings, and drive shaft) is one size larger than the element size normally used, the pump is referred to as an “M” frame pump (i.e. 2M1). Thus, a frame 3L2 and 2M1 would use a common drive end.Type designation is a series of letters which identify the “Materials of Construction” in component groups of parts. The usual type designation will consist of three letters.The first letter identifies the material of the suction housing casting or the body casting where the bearing housing is a part of the suction housing.The second letter indicates the material used in the drive shaft, pins, connecting rod, rotor, and other minor metallic parts in contact with the material being pumped.The third letter determines the material of the stator. It identifies only the stator material and not that of the tube in which the stator is placed.A typical type designation such as CDQ would result in the following:C = Cast Iron Suction HousingD Hardened Steel Internals includingdrive shaft, pins, connecting rod,rotor, and other minor metallic parts incontact with the material beingpumpedQ = Nitrile Synthetic Rubber Stator (70 durometer)The following letters identify the actual materials that are used in standard construction:B - EPDM Q - Nitrile (70 durometer)C - Cast Iron R - Natural Rubber (55durometer)D - Hardened Steel S - Stainless Steel, typeF - Fluoroelastomer #316G - Stainless Steel, T - Teflon (glass impreg-#416 nated)Also included on the nameplate is the three-character trim code designation. This only appears on pumps which have semi-standard or special construction. The first letter identifies sealing variations, the second character identifies internal variations, and the third letter identifies rotor variations.On page 5 of this manual are variations avail-able for modifying pumps to meet specialized pumping conditions. If the trim code of your pump is other than “AAA”, contact your nearest Moyno representative for clarification. Do not use any variation unless you have determined that it iscompatible with your application.• 2* ADD THIRD LETTER OF TYPE DESIGNATION TO COMPLETE PART NUMBER.

Disconnect the power source.2. Close the suction and discharge valves to isolate thepump from the line.3. Turn off flush water to packing or rotary seal if used.4. Remove drain plug in pump body to drain away any fluidremaining in pump.5. Place a support block under pump body in area of drainplug. Wooden blocks are sufficient. The purpose is to prevent undue stress on pump support when pump is disassembled.6. Disconnect piping from stator end of pump.7. Stator Removal - With pipe wrench or strap wrenchremove discharge reducer (U). Remove cap of stator support and with strap wrench or pipe wrench, unscrew the stator (Z) from the suction housing. Pull Stator off the rotor.8. Rotor Removal . The rotor (AA) is removed with theconnecting rod (Q) and rotor pin (S) as a unit. Removal of the unit is accomplished by removing the two drive pin retaining nuts (N) located in the shaft collar (J). This step reveals the shaft drive pin (R) which is removed by driving the pin from the drive shaft (V) with a small punch or drift pin. Slide the shaft collar toward the packing gland (W) and remove the retaining screw washers (O) from each side of the drive shaft. The rotor and connecting rod can now be removed by pulling them from the pump. To disassemble, clamp the connecting rod (Q) by its mid-section in a vise and witha drift pin, drive the pin retainer (K) from the head of therotor. The rotor pin (S) can now be removed from the rotor freeing the connecting rod. Remove the connecting rod washers (P) if present.9. To remove packing (X), remove nuts holding packinggland (W). Slip packing gland from studs, remove packing rings, lantern ring (M), and remaining packing rings. Packing rings can be removed with a standard packing puller. Note: If step 10 is to be per formed, it should precede step 9 as packing can then be removed by freeing packing gland and driving packing, lantern ring, and packing washer (Y) from housing using a small rod. Rod should enter where stator screws into pump body. Place rod on packing washer and tap. Entire set should easily exit from opposite end of stuffing box.10. Drive Shaft & Bearing Removal - With rotor removed itis now possible to remove the drive shaft and bearings as a sub-assembly. Remove the four cap screws holding the bearing cover plate (H) and slip from shaft.Insert a bar or rod into the hollow end of drive shaft (V) where it enters the suction cavity. By tapping on the rod the entire assembly will be forced from the pump body.To disassemble, remove bearing lock nut (D) and bearing lock washer (E). Using an arbor press remove radial bearing (A), bearing spacer (C), and thrust bearing (B). Apply pressure to inner race only.When replacing drive shaft and/or bearings, it is recommended that both grease seals be replaced.Grease seals are pressed into the bearing housing and bearing cover plate.Assembly ProcedureMoyno pumps are reassembled in the reverse order of disassembly with special notes as outlined below:1. Always replace all old washers, and packing. We alsorecommend replacing grease seals when new bearings are installed.2. Bearing Shaft Assembly - When installing new bearings,make sure that they are seated against the shoulder on the shaft. Replace bearing lock washer and bearing lock nut. Tighten bearing lock nut securely.- Bend tab down onto lock nut to prevent loosening of nut.Make sure that the shaft collar, packing gland, and packing washer are installed on the drive shaft as the hollow end emerges in the bearing housing and approaches the stuffing box area.When replacing the bearing cover plate, tighten all cap screws evenly to prevent damage to the bearing cover plate and thrust grease seal.Do not over-lubricate bearings. (See Maintenance) 3. When installing the connecting rod, make sure that thehole in the rod is aligned with the holes in the drive shaft and shaft collar before inserting the pin. Always use retaining nut washers. Insert pin, slip one retaining nut washer over each end of pin, attach nuts. Tighten nuts and slide shaft collar in to position to prevent nuts from turning. Tighten set screw in collar to lock it in place.4. When replacing packing, insert one ring on the shaft,the lantern ring, and then three more rings. This will allow the lantern ring to line up with the grease fitting on the stuffing box. Make sure you stagger the ends of the packing rings.When installing the new packing, you may find that all but one ring will go on the drive shaft. When the pump has run for a short time and the new packing is compressed, this final ring can be installed.5. When installing the stator on the rotor, it is best tolubricate the rotor with water (or a lubricant compatible with the rubber in the stator) to allow the stator to slip on easier. (Grease or oil is not compatible with type “R” or “B" stators.)When replacing the stator, always tighten it with the pipe wrench on the end of the stator nearest the suction housing. This will prevent it from binding and damaging the threads.If your stator has a stainless steel sleeve, use a teflon tape or similar material on the threads before replacing -- on all stators with a carbon steel sleeve, use pipe dope.46. Caution: Dry operation is harmful to the pump. Always fill the pump with fluid to be handled prior to start up. Check any valves in discharge line todetermine that no restrictions exist.MAINTENANCEThe Moyno pump has been designed for a minimum ofmaintenance, the extent of which is routine lubrication and adjustment of packing and infrequent lubrication of the bearings. The pump is one of the easiest to work on in that the main elements are very accessible and require few tools to disassemble. PackingThe Moyno pump is normally furnished with die formedpacking. The packing may be either grease lubricated through a grease fitting in the stuffing box or have plumbing connected to the housing to allow a water flush. (See Water Flush of Packing)Packing gland adjusting nuts should be evenly adjustedso they are little more than finger tight. Over-tightening of the packing gland may result in premature packing failure and possible damage to the shaft and gland. When the packing is new, frequent minor adjustments are recommended for the first few hours of operation in order to compress and seat the packing. Greasing the packing often but with limited quantities of grease is the best practice. This can be done through a grease fitting which leads to a lantern ring in the mid-section of the packing. Do not use a one-piece spiralwrap of packing. Water Flush of PackingWhen the material being pumped is abrasive in nature, it may be advantageous to flush the packing to prevent leakage under packing and excessive shaft wear. Clean water can be injected through a 1/8” NPT tappedhole that normally houses the grease fitting for lubricating the packing. The water can be permitted to leak axially along the shaft in either direction or can be removed from the second tapped hole in the stuffing box. In both cases, the discharge from the stuffing box should be throttled slightly to maintain 10-15 PSI higher pressure in the stuffing box than is present in the suction housing. This is a basic arrangement, other variations can be used. (1) Throttling Valve (2) Pressure Guage (3) Pressure Regulating Valve Bearings The Moyno pump is equipped with ball bearings in the drive end size L2 through L10. The bearings are lubricated at the factory and do not need additional lubrication for at least 1500 hours of normal operation. When relubricating the bearings, the bearing-shaft assembly should be removed (See Disassembly instructions) and cleaned of old grease. Add only enough grease to fill the area between the bearings 1/3 full. Add a few drops of oil to bearing seals before reassembling. It is normal for bearings to run warm to the touch for the first few hours of operation. Any type of Ep Lithium soap base grease is satisfactory for bearing lubrication. The use of Sodium or Calcium base grease is not recommended. The following is a partial listing of approved bearing lubricants: Dow Corning DC 33 Keystone Lubricating Co. Keystone #89 Texaco Regal AFB2 Shell Oil Co. Cyprina #3 Humble Oil & Refining Co. Beacon 325 American Oil Co. Supermil Grease #A72832 Mobil EPI Shell Oil Co.

3.1主轴及其驱动系统
主轴(1)是由S-C Z K Y无级直流电机(2)和P W M C脉宽调速控制系统组成,该系统电机的额定力矩为5N·m,脉宽调速范围为10-1500r/m i n,无级恒扭矩,高速精度为1%.该直流电机最大功
率约 1.2K w,在主轴(1)和直流电机(2)上部
,分别装有从动和主动特制的圆弧齿形带轮(3)、(4),通过圆弧齿同步带(5)把直流电机的功率传递到主轴上。
由于应用了脉宽调速系统使其在低转速下具有高的传动力矩,它完全改变了可控硅无级变速系统在低转速下传动力成倍递减的特点。
3.2油盒与摩擦副加热升温系统:
主轴(1)是空心轴,其最下端有1:7的锥孔,可以安装各种各样的摩擦副上夹头,例如,销盘夹头(10)和销盘摩擦副(11)、(12),空心主轴内有拉杆(6),当销盘摩擦副等夹头装入主轴锥孔内,旋紧拉杆(6)可确保主轴与各个摩擦副上夹头在主轴锥孔内不产生任何相对滑动。
油盒加热系统有两套,分别是不锈钢套式加垫圈(13)和加热板(14),均在220V,条件下,通过继电器对试验温度从室温~100℃进行数显控制与报警,进行工作,在两种油盒加热器中都装有P t—100Ω标准铂电阻。
3.3下导向主轴与下摩擦副副盘及摩擦力矩传感系统。
下导向主轴(15)副盘(16),直线球轴承(17),两个径向球轴承(18),试验力传感器(19),摩擦力传感器(20),止推球轴承(21),背紧螺母(22),滚花螺钉23),再更换夹头与装卸各种摩擦副时必须操作(22)与(23),直线球轴承(17)可使下导向主轴(15)上下运动,摩擦力小,轻便灵活,它可使在施加试验力时具有较高的灵敏度,轴承(18)可使传递摩擦力时数显准确可靠。
本机力值标定,是由专用工具和标准牛顿砝码检定,以确保本试验机与摩擦力矩按计量法规定传递精度准确可靠。
3.4弹簧式微机施力系统
试验机试验力的施加是通过弹簧式施力结构与微机控制步进电机系统自动进行,步进电机(30)通过一对径向止推球轴承
(31),(32),传递一对减速比为80:1的蜗杆(28)蜗轮(29)运行
副。
蜗轮(29)固定着一根丝杠(25),由一对径向止推滚子轴承(27)使下螺母施力板上下移动(有两根固定立柱作导向)压缩施力弹簧(24),通过上施力板,荷重传感器(19)把试验力施加到不同的摩擦副上产生接触压力,并按要求进行试验。
操纵试验力控制按钮,通过微机控制自动加载系统可实现按一定速率加载。
行程限位开关可在试验结束后自动卸载后起限位停机作用。

3.6试验机控制面板系统
试验机的控制箱在机座上方右侧是电脑显示器。
打开后盖可看到电脑控制箱,通过相应参数的设置可实现对试验机的操作。
4:试验机面板系统的操作
试验机的操作面板(如图7):
4.1试验操作:
面板如图2所示,首先应接通试验机电源(电源为220V、50H z交流电),按下电源开按扭,及显示器旁的电脑主机开关,从桌面上打开控制系统。
试验之前首先装好试样,选择试验方法,对试验力、摩擦力、进行清零。
并对各参数进行设置。
先手动调整,通过滚花螺钉使试样上升,当上下摩擦副接近时,选择自动加载,当试验力值稳定后试验开始,时间、摩擦力等开始计数。
4.2具体操作可以参照以下步骤:
1.接通电源,检查电源是否正常,若正常,进行第二步操作,若
不正常,检查供电电源及强电板上的空气开关是否已接通。
2.查看主轴轴旋转方向是否正确,该试验机的主轴不可逆转,既
从上往下看是主轴为顺时针旋转。
3.安装试样,具体安装方式可参照图2-图6。
4.试样安装完毕,将上试样夹头镶在主轴下端锥孔内,旋紧拉杆,
下试样放入试样座相应位置,手动旋转滚花螺钉,让下导向主轴上升,使上下摩擦副相互接近。
5.选择试试验验方法,进行参数设定,调整加载速度,按下自动
加载按扭,试验力值稳定后,按下开始按扭试验开始。
6.当做高温长时四球磨损试验时,应将高温油盒安装至试验副盘
上之后接通温度控制器电源。
当温度快要到达设定温度时,手动旋转滚花螺钉,使下导向轴上升,让油盒上升到接近弹簧夹头位置,进行参数设置,继续升温过程中使用自动控制模式达到设定力值。
当温度到达设定温度之后,按下开始按扭,试验开始。
(温度设定参数已完成,不必改变其中的参数)。
7.试验结束后,将试验力设为“零”,系统会自动卸载;或点下
手动加载,将控制条向左拉。
当试验力下降到“零”时,点击停止按扭,手动旋转滚花螺钉,使导向主轴下降,取下试样,分析试验结果。
8.如作低速试验,请将驱动装置更换为1:20减速装置。
