To belt conveyor abnormal noise causes and treatment

 Run of the belt conveyor drive unit, the drive roller and bend pulley, and idlers in normal emits unusual noises, can determine the device under abnormal noise Malfunction.industrial conveyor

Runtime of a roller eccentric serious noise when the belt conveyor idlers often abnormal noise occurs, accompanied by periodic vibration. In particular, the return roller, because of its greater length

Self-important, the noise is relatively large. The noise occurred mainly due to two reasons. First, manufacturing roller seamless steel pipe wall thickness is uneven, the centrifugal force generated. Two

Processing both ends of the bearing center of the hole and the outer circle center deviation is large, so that the centrifugal force is too large. Can continue to use in the case of bearing damage and to allow the presence of noise.

2 two-axis misalignment noise coupling between the high-speed end of the drive unit motor and reducer coupling with brake wheel coupling issued by the unusual noise, such

The noise associated with the motor rotational vibration of the same frequency. When this noise should be timely adjust the position of the motor reducer to avoid the input shaft fracture.check weigher

Idler pulleys bend pulley and drive rollers work properly with the drive roller abnormal noise when the noise is small, abnormal noise bearing damage at the housing hair

A gurgling sound, this time to replace the bearings.

The application of air-cushion belt conveyor

Already widely used in China belt conveyor roller bearing conveyor support form intermittent contact support, so the transportation of materials will cause vibration and transport

Loss resistance is relatively large. To overcome these shortcomings, it is committed to exploring new belt conveyor, have appeared in the cushion, magnetic pads and water cushion belt conveyor, their common

The characteristics of non-contact continuous support. Cushion belt conveyor in addition to the formation of the part of the air cushion with Universal belt conveyor structure basically the same, the belt conveyor

Blower, connecting pipe, air box and disc slot, and remove most of the carrying idlers.portable conveyor

The belt conveyor can meet the special materials transport requirements. Blower air volume is to meet the air loss of the air cushion belt conveyor and full of gas within seconds

Box to achieve sufficient pressure to form a cushion material on the conveyor belt, even intermittently, can transport as usual, due to the discharge pressure air is always from the pores of the gas tank. Because

This does not affect the carrying light and heavy at the air cushion. Due to the pressure of the air pressure is greater than the gravity of the material, Gravity roller conveyortogether with air having a certain speed, the fine powder material does not enter the

The air-cushion space wear caused by the gas tank and the conveyor belt, and also will not clog the pores, but also can be used to cycle sealed chamber, in order to meet the delivery of chemical, pharmaceutical and other toxic materials.

Features of the belt conveyor

The air-cushion belt conveyor is usually divided into two categories. Only in the bearing section called half cushion; bearing segment in the return section cushion cushion called cushion. The former should be

More, which is seldom used. 2.1 working principle, the majority of our semi-air-cushion (only the upper air box, while the lower roller bearing), and the majority of the straight edge round

Arcuate. plastic chain conveyorIts working principle is: will have some pressure on the flow of air into the chamber through a small centrifugal fan (2-18 SKW) exhaust holes on the air flow through the tray slot

Enter between the tape and disk slot. Since air has a certain viscosity, in the process through the tape for rent between the grooves will form a stable gas a thin film (commonly

Said air cushion). This layer of air film tape material on the float, but also play the role of lubricant, when the drive motor is activated, the tape around the drum run conveyor

Materials. 2.2 Features

(1) energy consumption. The upper branch of the belt conveyor without roller bearing, the friction coefficient is significantly reduced. The air cushion machine test measured 0.002 -0.031 roller belt conveyor

The machine measured 0.008-0. 037, the running resistance than the roller tape machine, so energy-saving.

(2) thinning the thickness of the tape. As the running resistance decreases, compared with roller belt conveyor, conveying the same amount of material, with thick can be thinned layer.

(3) smooth running, reliable, wide range of applications. Cushion belt conveyor tape floating in the gas film is running very smooth, so the material will not be scattered,

Eliminates tape accidents caused by tearing up the scattered materials.skate roller conveyor

(4) tape deviation, long life. The chamber of the air cushion machine alignment, there is no branch deviation component perpendicular to the surface of the disk slot, because the pores of the aircraft, from stomatal

Used in gas pressure depends on the material pressure. When the deviation when the conveyor, the conveyor on both sides of the centerline of the gas to change the direction of the center line of the thrust of its force and

The deviation in the opposite direction, the conveyor belt back to the passage of time, thereby avoiding the deviation of the conveyor belt. As the belt floating on the gas film, without contact with the support means, with the carrier

Becomes rolling friction between the roller and with air as the medium of the fluid friction, thereby reducing the tension of the conveyor belt and the running resistance of the bearer, is also decreased in the same circumstances the conveyor belt

The strength requirements and the required drive power, and also a corresponding increase in the life of the tape.

Belt Conveyor Idler deviation debugging method

Resistance to eliminate less severe: If conveyer, conveyor belt should run laterality roller cleaned, and a few drops of machine oil on the roller bearings to reduce the idlers

The frictional resistance, the angular velocity of rotation of the roller to speed up, you can eliminate the deviation.

Material flow correction method: If the belt-load deviation, heavy-duty operation deviation, the uneven distribution of the material on the conveyor belt, feed valve is not correct, it should be corrected feed downpipe

Or the installation guide plate to change the blanking position, to adjust the material flow directions, so that uniform distribution of material on both sides of the conveyor belt.pallet conveyor

Joint correction method: If the conveyor belt is running and always to the side deviation, maximum deviation just in the joints, and the deviation of the position is uncertain. Conveyor belt joint is not correct, it should be recalibrated

Connector or glued joints.

Stent correction method: the conveyor belt running to the same side of the deviation, and more serious in the same location, said the Minto roller stand or rack distorted errors should be corrected stand or rack water

Roughness and vertical, replace the are serious distortions bracket or rack.

Conveyor belt repair method: If the edge of the conveyor belt is badly worn, so inconsistent on both sides of the conveyor belt tension, the belt running position is not fixed, according to the actual situation should be promptly repaired or

Profile.Metal detector for food

Idlers of offset method: such as the total conveyor-load to the side deviation in conveyor belt run laterality center position a roller frame rack join the four mounting bolts Remove the three

, Leaving a when the shaft when one side of the conveyor belt to the stand deviation forward movement of the bracket along the conveyor belt running direction of the appropriate angle and then fixed. Conversely, when the conveying

With toward the other side of the deviation, you can send the bracket to move in the direction of the conveyor belt running the appropriate angle and then fixed conveyor belt deviation phenomenon will disappear

Tensioning device method: If the conveyor belt to load or reload run to the same side of the deviation, the degree of tightness on both sides of the conveyor belt is inconsistent, according to the law of "running tight do not run loose"

Drum at the front and rear adjustment screw or counterweight tensioning device, the conveyor belt will be reset to normal operation.

The belt conveyor deviation maintenance method

Conveyer belt conveyor belt running adjustment is a common fault in the belt conveyor is running. It is not only serious wear and tear caused by the edge of the conveyor belt, and will

Conveyor tear sudden accident, the early failure of the conveyor belt, causing economic losses. The author based on many years of production experience, and explore got some belt lose

Belt deviation and adjust the law of the sending machine.

"Tight run do not run loose": belt conveyor is running, if the front and rear roller is not parallel, resulting in inconsistent degree of tightness on both sides of the conveyor belt, the conveyor belt to the tight side

Offset;air to water heat exchanger
"Run high running low": the same horizontal position on the idler is not in parallel with the conveyor belt running direction, but the end of the high, one low, and then shifted to the high end of conveyor belt

;
"Run do not run before": not cross section perpendicular to the direction of the conveyor belt running roller on the rearward end offset but one end, after the end of the conveyor belt. According to the conveyor belt running

The partial specific circumstances, we have mastered the number of viable adjustment method, mainly the following methods.
The of offset roller law: generally applicable to belt conveyor deviation range is not too large, automatically adjust the bias roller groove tune, the use of a conveyor belt does not run after run "law of adjustment, when the input

Belt deviation, met groove of offset care small block roller on the roller due to the the retaining roller and the friction of the belt edge and along the running direction of the belt to move forward, another lateral move

Block roller conveyor belt toward the turn side to move until you return to the normal position.industrial belt conveyor
Vertical roll of offset method: If the conveyor belt running total to the side deviation, laterality of the roller is mounted vertically in the conveyor belt run. On the one hand the conveyor belt due to the force of the vertical roll force

Reset, on the other hand due to the friction of the vertical roller conveyor, reducing the linear velocity of the conveyor belt running laterality, the relative increase in line speed of the conveyor belt and the other side until the Loss

Sent with reset.
Gravity of offset method: If the conveyor belt heavy-duty running deviation, laterality run the conveyor belt rollers and roller frame appropriate heightening the material on the conveyor belt to the weight of an anti-

Deviation component ended conveyor belt until the belt back to the normal position.
Booster of offset method: If the conveyor belt idling total deviation to a side, do not run "running high" regular adjustment, the relative deviation of the other side of the roller frame appropriate booster,

Values ​​before and after the booster the first paving roller prevail, slowly reduce the booster, the deviation of the conveyor belt will naturally disappear.
The roller cleaning method: If the conveyor belt run on a fixed point and fixed, it is required to check whether the point of roller stall, sticky mud drum diameter larger or reducers

Roller off failure to take the appropriate measures, depending on the circumstances.
Adjusting device method: If the deviation around the conveyor belt, no fixed direction, the conveyor belt slack should be adjusted tensioning device, the tension of the conveyor belt, the deviation phenomenon disappear naturally.
