How to troubleshoot the daily malfunction of vibrating motor?

1. after connect the power supply, motor is unable to start, please check:

(1) if power supply is lack of phase;

(2) if motor is loss of phase;

(3) if protective cover is damaged or rub eccentric block.

2. after start-up, there is big motor noise or motor heats, please check:

(1) if the contact surface roughness of vibration machine and motor foundation is in line with the installation requirements;

(2)if the anchor bolts are not tighten up ;

(3) if the vibration acceleration is in line with the requirements;

3. after the adjustment of eccentric block, amplitude changes abnormally please check:

If eccentric block on both ends of the rotor axis is symmetrical;

4. when two vibrating motors of vibration machine vibrate at the same time, if its phase does not conform to the requirements, please adjust the phase sequence of the single unit, don't adjust the total phase sequence of two vibrating motors.

Shuttle Conveyor Introduction

Shuttle conveyor is designed for conveying material moves along a transport direction on the steel track which is usually installed on the top of the storehouse.Reversible conveyor mainly used to discharge material constantly in multi-point when the discharging points could move.
► Advantages

1.Multiple discharge point

2.Discharge continuously in long distance

3.Two way running and discharging

4.Compact structure with low height

5.Convenient installation and maintenance

shuttle conveyor

► Application
Large capacity shuttle conveyor is mainly used for disperse and store the material, especially the materials need to discharge averagely in order to take full advantage of the space and then store more material. So it could be used in agriculture, power plant, raw material stocking, metallurgy industry, etc.

The belt running deviation is rather harmful during the operation. According to the actual operation of belt conveyor, the deviation effects on the operation and production of belt conveyors are mainly in the following aspects:
1. Failure breakdown emergency stop device
The failure breakdown emergency stop device with protective purposes is installed on the belt conveyor. When the belt deviation occur and near the failure breakdown emergency stop device, it will causes the device to stop the machine immediately, and hence causes the conveying process to stop. This will affect the efficiency of production line, and hence increase the cost of production. Some serious cases might lead the project unable to finish on time, or even causes the undesirable contract disputes.

2. Reduce the life-span of main components
Firstly, the breakdown of roller, bearings and other mechanical components, such as belt running deviates frompulley will cause the increasing of the force of roller, and hence it will increase the probability of failure. Secondly, it leads the belt to be worn out in a shorter period. The belt running deviation cause the materials spread onto the return belt. It will cause the belt and roller encapsulate to wear and tear abnormally as the materials can’t be fully removed from the return belt. Thus, the life-span of belt and roller will be shorten. Thirdly, it leads the tear and wear from the edge of belt, if the edge of belt collides with frame for a long time during the operation, it will cause the severe wear of belt edge and thus affects the life-span of belt which will leads to the increase of maintenance cost and also the operation cost. When the serious belt deviation occurs, it causes belt tearing directly. Belt deviation might lead to serious overturning of belt, causing the increasing of unilateral force ,hence it will lead to belt transverse fracture.

How to #select suitable #belt for #corrugated #sidewall #conveyor?

Corrugated sidewall belt is used for pulling and carrying purposes for corrugated sidewall conveyor. It consists of a baseband, corrugated sidewall and baffle. The corrugated sidewall connects with both sides of baseband while the baffle connects with both side of corrugated wall accordingly to a certain space. 1. Baseband
The baseband appearance of corrugated sidewall belt is the same with ordinary belt ,but its lateral stiffness is greater than ordinary belt. Usually corrugated sidewall belt adopts special belt as its baseband, the tensile materials (core layer) can be divided into four kinds: cotton canvas, nylon canvas, polyester canvas and steel wire. 2. Corrugated sidewall
This series of products using S-type of corrugated sidewall.

3. Baffle
a) This series of product is recommended to use type T, type TS (B), type TC, type TCS (B) and type C baffles.
b) Type T and type TS (B) baffles are only suitable for conveyor angle β≤40 ° while type TC and type TCS (B) and type C of baffles are suitable for conveyors with any transmission angle.
c) Type C baffle is suitable for conveying viscous materials. On the other hand, if the conveying angle and material density are greater, then type TCS (b) baffle should be used.
d) The spacing between baffles is integral multiple of waveform of the corrugated sidewall. The spacing between baffles (TS) and height (H) are related to conveying angle β.

The Role of Conveyor Belt Cleaning Device

The belt conveyor is often used to transport viscous materials, such as coal dust, mud, powder materials and etc.. Some of them will stick on the working surface of belt conveyor, which cannot be removed when discharged the materials. At this time, the adhesive material will then enter the return idler, the roller become dirty as attachment stick on it. Materials enter the roller casing, thereby increasing the radial and thrust load of bearing block, causing rapid wear of bearing. The materials deposit on the roller casing will tear the rubber surface of the belt conveyor, accelerate the wear out failure of belt conveyor. If sticky materials enter the tail bend pulley, it will stick on the surface of roller. The more the viscous materials stick on it, the greater the force of the sticky materials, which will result belt deviation and increase belt wear, leading to serious consequences.

The remaining material on the belt conveyor will increase the friction force on roller, sometimes it may cause the tear on the rubber surface of belt conveyor and also the layer of roller encapsulate. If the cleaning device can function well, it can prolong the service life of the roller, belt conveyor and etc.. This shows that the cleaning device has a significant effect on belt conveyor. In the process of operation, if you want to clean the sticky material on the tail bend pulley through anthropogenic removal, it often prone to serious bodily injury or death. Hence, in order to ensure the normal operation of the belt conveyor, the sticky material must be cleaned up by cleaning device before materials enter into the snub pulley.
