3 Design vantages DIS. UORIZDO Mesur-Fil Fluid ouplings allow motors to start unloaded and to reach operating speed with smooth, controlled acceleration. his makes it ideal for applications with high inertia loads. hey are available in either constant or delay fill versions. ll luminum Housing for Low Rotating Inertia Impeller High emperature Viton Seals Runner ollet Mounted For Ease of Mounting Smaller Sizes One Piece onstruction (smaller sizes) Eliminates Leaks. Benefits Mesur-Fil Fluid ouplings offer several advantages: Reduced energy consumption Jam/overload protection Shock load cushioning No metal-to-metal contact Wide range of available mounting options High temperature Viton seals vailable from over 7 Formsprag uthorized Distributors. here are three primary components to Mesur-Fil Fluid ouplings: 1. Vaned runner 2. Vaned impeller 3. Fluid fill INPU Motor Runner Fluid orque, produced by the prime mover (motor) acting on a vaned runner, is transmitted through the flow of fluid into the chambers formed by the two Principle of Operation Impeller OUPU Load coupling halves. he oil (fluid) is subsequently thrown into the vaned impeller connected to the load causing it to turn. It is important to note, that as this transmission of power takes place, there is virtually no wear on the transmitting parts because there is no mechanical contact between them. 136

4 DIS. UORIZDO Fluid Requirements Figure 2 reveals a typical NEM B electric motor torque curve together with the particular operating characteristics of a specific coupling with a designated fill level. With no power supplied, all of the fluid is settled at the bottom of the coupling. Slip rate in this condition is 1% with the input free to turn. With the motor starting and increasing in speed to the breakdown point, torque builds in the coupling. s torque increases, the coupling begins to deliver the load to the motor, eventually bringing the load up to speed (refer to the load acceleration area in fig. 2.).

Motor Breakdown Points Starting orque % Full Load oupling Fill Effect ypical NEM B Motor Red Green Blue Green Red oupling Input Speed % Motor Sychronous Speed he area on the chart between the motor torque curve and the 1% slip curve represents the excess torque available to the motor to start itself without also having to start the load. It is this operating characteristic which permits a soft start with a onethird lower current draw on the motor. (See fig.3.) (It should be noted that because the coupling torque can only be developed if the runner is turning at a slower speed than the impeller, an ideal small amount of slip of to is necessary). he Mesur-Fil Fluid oupling provides for jam load protection to the motor and other vital power system components. It is designed to allow the motor to decelerate only to its breakdown point (fig. 4). he results without the fluid coupling could be a locked rotor condition, resulting in excessive current draw and potential motor damage. dditionally, the coupling distributes the shock of an overload over a longer time span, thus reducing the possibility of damage. Motor Breakdown Point 1% 1% 1% 1 2% 3 Less han 1 Red: oo Much Fluid Green: Right mount Of Fluid Blue: Not Enough Fluid Delayed Fill Mesur-Fil Fluid ouplings, sizes 15 through 34 (3 to 15 hp.), have an available delayed fill option restricting starting torque to 14% of full load while still ensuring low slip at full speed. he result is a softer, more gradual start which can be advantageous for applications such as belt conveyors and mixers. he operating principles are simple. With the idle coupling (fig. 5) the purpose of the delayed fill chamber is to isolate a portion of the fluid from the main coupling. s the runner accelerates (fig. 6), the chamber attached to the runner gradually releases fluid into the main coupling through specially calibrated orifices. he fill increases proportionally with the output speed. With acceleration complete (fig. 7) at the high speed running position, almost all of the fluid has been released from the chamber into the coupling, giving the coupling high fill/low slip characteristics.

7 DIS. UORIZDO Selection and Sizing Fill Levels (NEM B Motors) he Quick Selection hart (fig. 8) provides the correct size coupling and fill level for any standard NEM B motor within the Mesur-Fil range. It also provides the slip rate that can be anticipated at normal operating speed. Having the correct amount of oil in the coupling is extremely critical to ensure safe and proper operation. Figure 9 shows the effects of either too much or too little fluid. With an optimum amount of fluid, the breakdown point of the motor with the 1% slip line of the coupling provide the best combination of soft start with slip rate at normal speed. With too much fluid (red area), the slip rate is lower and the start is harder. With too little fluid (blue area), the start will be softer but the slip rate will be much higher. his can cause heat dissipation problems, and, in extreme situations, the coupling may completely fail to move the load. choice of fluids is also available. In a normal environment, petroleum oil is the best fluid to use. For hazardous conditions such as those encountering dust, paint spray, etc., a special fire-resistant fluid may be required. Delay chamber is recommended for the following applications: Figure 9 oupling Fill Effect Starting orque % Full Load Overland conveyors Blowers/Fans Mixers rushers Excavators Mills Large inertia drives entrifuges ypical NEM B Motor Red Green Blue Green Red oupling Input Speed % Motor Sychronous Speed Figure 8 Quick Selection hart 12 RPM 18 RPM HP plg.

In order to avoid this damage, in critical applications, it is advisable to install a fusible plug instead of a solid plug. Overload protection. For sizes 7. to 12.4 a 25 F fusible plug is available only as an option. For sizes 15 to 34 a 29 F fusible plug is standard. ( 25 F or 35 F fusible plug is available as an option.) Fusible pin For sizes It's possible to avoid loss of oil from the unit by fitting a fusible pin. When temperature increases, reaching melting point of fusible element, a pin is released and touches a cam mounted on a relay which gives an alarm or switches off the electric motor. Like the fusible plug there are three different fusible elements. his solution needs only the replacing of the fusible element or fusible pin. Electronic overload controller (orque limiter) For sizes his device measures the speed of the coupling, stopping the motor or giving a signal when the preselected limit is exceeded. With this device nothing has to be replaced, and after having eliminated the cause of the overload, the transmission can run normally. 141

If the pullout torque is unknown, then assume 2% of normal rating occuring at a speed of 154 RPM, with full motor speed of 175 RPM. Pullout torque = 2 * 22.5 lb.ft. = 45 lb.ft. Locate the pullout torque against RPM curve to insure the point is slightly above the drag torque line. Locate the normal torque against RPM curve to insure the point is below the 7% slip line. Ideally, plot the point between and slip line. 143
