Faults od a dual motor drive belt conveyour

Conveyor Belt Mistracking. This issue occurs when there is a conveyor belt tracking problem. Tracking is the process of managing and aligning the belt onto the correct path, and it’s critical to ensuring the smooth functioning and output of your system. Mistracking, then, is

All belt bounce was eliminated by switching from a single head drive to a dual (head and tail) drive system. Two 50 HP 24 inch diameter Motorized Pulleys replaced one 75 HP exposed drive system. Prior to installation, the operator expressed concern about installing a drive in the tunnel because it was subject to flooding

F. The conveyor frame is not square or the system is not properly supported. Straighten the frame in the affected area and check to make sure support in that area is correct. 7. Belt slips when conveyor is started. A. Insufficient traction between belt and drive pulley. Make sure drive pulley is free of build up. Lag Drive pulley

Apr 05, 2018 Apr 05, 2018 Belts, along with electric motors, shafts, and pulleys, are a critical component of power transmission in belt drive systems. While belts require very little maintenance, improper belt tension, misalignment of pulleys, mishandling of belts, and environmental factors are common problems that can shorten the life of your belts and bring your system to a halt

Aug 08, 2016 Aug 08, 2016 I have a dual drive conveyor that is starting to puzzle me. One side has always had a bit of a resonance, but lately, when the belt is unloaded and first staring up I'm starting to get a pretty violent shudder on the motor and platform. There is one Vibe sensor on the input of the gearbox that shuts the system down at .6 In/Sec. The vibe sensor has been tripping during start ups

Feb 21, 2003 Conveyor Dynamics Inc. 1. In dual drives there is always the problem of unequal load sharing between primary and secondary drives when motor ratings of primary and secondary are same. Answer: There is a problem with the loss of belt length across the drive pulley due to loss of tension - ie low modulus belt

Aug 18, 2008 I have a problem with a new dual drive installation that is baffling me. It is a 48 conveyor running a 600 FPM carrying about 2800 TPH of rock salt. Center to center of belt is 3500 ft with a 33' net lift. I have 2 identical 250 HP motors 1780 RPM - 2300 VAC and 2 identical gear boxes Sumitomo PX8075 running 2 different pulleys on the return side of the belt approx 500' from the head

The drive unit consist of electric motor, dam ping coupling, two or three stage gear- ... who compared the total number of identified faults on belt conveyor gearboxes over a 13-year period. If we

May 21, 2012 Each motor will be controlled by an individual VFD. At times only one motor will be necessary to drive the conveyor. The conveyor belt is on opposing sides of the motors (i.e. top side for motor 1 and bottom side for motor 2), so our intention is to use the torque control feature in a Master/Slave scenario

4.5 Drive Standards. CONCLUSION SUMMARY. This paper has been prepared with the intention of highlighting the problems faced by design engineers who are forced to undertake the design of belt conveyor systems using a multitude of design standards which have not been brought into line with modern technological advancements

A flux vector VFD drives each Motorized Pulley. They were originally programmed to drive the conveyor at 60 Hz. At that time, the reclaim conveyor, fed by six belt feeders, moved “high calcium” hard rock and a mixture of other ingredients at 500 tph at a nominal belt speed of 384 fpm during 10% of

There are various options, including self-cleaning tail pulleys, v-ploughs (return side belt cleaners), and dual belt cleaners. A conveyor belt maintenance plan should also include routine cleaning to minimize residue on components. 2. Conveyor Belt Mistracking. Conveyor belt mistracking refers to the way the conveyor belt runs on the rollers

Drive motor = 22.4 kW Head shaft = 18.48 RPM 225% Electric motor = 1.30 S.F. Sizing Example No. 2 Application: Dual drive on Head Pulley - Single Backstop Steel Company, USA Data: Drive motor = 2 @ 750 kW Head shaft = 30.16 RPM 175% Electric motor = 1.00 S.F. 460 mm max bore Sizing Example No. 3 Application: Dual drive on Head Pulley – Dual

Mar 29, 2018 Conveyor Belt Mistracking. This issue occurs when there is a conveyor belt tracking problem. Tracking is the process of managing and aligning the belt onto the correct path, and it’s critical to ensuring the smooth functioning and output of your system. Mistracking, then, is when something goes wrong along this track

Aug 18, 2014 Aug 18, 2014 Enclose conveyor for protection against rain, snow and sun. Don’t over-lubricate idlers. Differential speed wrong on dual pulleys: Make necessary adjustment. Drive underbelted: Recalculate maximum belt tensions and select correct belt. If conveyor is over-extended, consider using two-flight system with transfer point

Apr 05, 2018 Apr 05, 2018 Belts, along with electric motors, shafts, and pulleys, are a critical component of power transmission in belt drive systems. While belts require very little maintenance, improper belt tension, misalignment of pulleys, mishandling of belts, and environmental factors are common problems that can shorten the life of your belts and bring your system to a halt

Different faults appear when the pulley-belt system is operating like unbalance, misalignment, belt worm and chirp noise [6]. The results of Fast Fourier Transform FFT explained the effect of each

Jun 11, 2020 Jun 11, 2020 Treatment methods: check the line; check the voltage; check the overloaded electrical appliances; reduce the number of operations. 2. Common faults: the motor heats up. Analysis of the cause of the failure: due to overload, overlength, or conveyor belt being stuck, the operating resistance will increase and the motor will operate in an overload
