provide information for alternate conveyor designs. Basic Power Requirements The horsepower, hp, required at the drive of a belt conveyor, is derived from the pounds of the effective tension, T e, required at the drive pulley to propel or restrain the loaded conveyor at the design velocity of the belt V, in fpm: (1) To determine the effective tension,
Calculate gearbox ratio = Input Speed/ Output speed 2. Select Gearbox Size from Mechanical Capacity. Determine type of load from table uniform, moderate shock or heavy shock). Determine mechanical service factor from table 1. Calculate the required mechanical power capacity (Pm )
calculated the horse power rating of standard ANSI roller chains; calculated the volume of bulk materials transported by horizontal and inclined drag chain conveyors; estimated dimensions of drag chain conveyors; and; use Excel's "Goal Seek" to optimize the engineering and design of roller chain drives and drag chain conveyors.
• A ball screw transforms rotational motion into translational motion. As a result, the shaft is subject to loads: – Thrust force (the sum of all external forces such as machining load, gravity, friction, inertial forces, etc.). – Torque required to generate the thrust force. ME EN 7960 – Precision Machine Design – Ball Screw Calculations 44
KWS Screw Conveyors are used to efficiently convey bulk materials from one process to another. Screw conveyors are very costeffective and require minimal maintenance to operate. Ideal for conveying dry to semifluid materials – freeflowing to sluggish; Efficiently distributes bulk materials to various locations using multiple discharge points
Sample Calculation. The motor speed under load is simply the noload speed less the reduction in speed due to the load. The proportionality constant for the relationship between motor speed and motor torque is the slope of the torque vs. speed curve, given by the motor noload speed divided by the stall torque.
It's necessary to calculate head, flow rate and useful power of centrifugal pump pumping lowviscosity fluid with density of 1,020 kg /m 3 from tank with overpressure bar to tank with overpressure bar along given pipeline with pipe diameter 20 cm. Total pipeline length (summarily with equivalent length of local resistances) equals to ...

It is the hydraulic power communicated to the liquid of its passage through the pump. This mechanical power is given by the following formula: With: P = Power transmitted to the fluid by the pump in Watt. Q = Flow in m3/s. Hm = Energy or pressure loss of the hydraulic network expressed in m.
To calculate multiple pulley sets, where the first driven (large) pulley shaft drives the second driver (small) pulley, and so on, enter first (small) driver pulley RPM and pulley set diameters and centers separated by commas and as shown below.
Inclination or Slope Chart. Use this chart to estimate the inclination or slope angle of a conveyor. Measure the horizontal run and the vertical rise of the conveyor. Draw the lines in the chart to estimate inclination.
Selecting the proper motor and driver to meet a specific application needs motor torque calculation. Generally speaking, the user can follow the below steps to choose the proper motor and driver. 1. Determine the motion profile and calculate acceleration, deceleration and maximum velocity required to make the desired move.
Understanding Motor Nameplate Information NEMA v/s IEC Standards ... conveyors, beltdriven equipment, machine tools, reciprocating pumps and compressors, etc. ... install an induction motor with a 15minute rating to power a preoperation oil pump used to prelube a
Calculation for Required Torque ( TM ) The required torque is calculated by multiplying the sum of load torque and acceleration torque by the safety factor. Calculation for the Effective Load Torque ( Trms ) for Servo Motors and BX Series Brushless Motors. When the required torque for the motor varies over time, determine if the motor can be used by calculating the effective load torque.
To calculate the speed of a motor, the following formula can be used: n = 2 x f x 60 p n = speed f = net frequency p = number of poles Example: 4pole motor running at 50 Hz n = 2 x 50 x 60 = 1500 rpm 4 This speed is the synchronous speed and a squirrelcage or a slipring motor can never reach it.
The actual screw conveyor speed is calculated by dividing the Selection Capacity by the capacity at rpm. 1,873/ = rpm rpm is the correct speed for a inch diameter screw conveyor with cut and folded flights and short pitch for conveying and mixing 333 cubic feet per hour.
•To calculate the design power it is necessary to determine the service factor for the drive. Using the service factor, determine the type of driven machine. •Using the service factor chart, determine the service factor for the driven machine the type of operational service.
