What should I do if the belt is aged and damaged due to too long mixing time? How should it be resol

As an important part of the operation of the car, the automobile belt connects various parts, which can be said to affect the whole body. In the event of a break or slippage, the air conditioning compressor, power steering oil pump, alternator, etc. will stop working. Therefore, it is very necessary to master the identification method of the advantages and disadvantages of automobile belts.

1. Identify the advantages and disadvantages when purchasing:

Smell it. The first step in the identification of the quality of automobile belts is to ask about the taste of the belt, which is the most direct and effective way. Generally speaking, inferior rubber products will have a pungent smell of glue, while good belts do not, and only a little attention can be well identified when buying belts.

Glance. Directly with the naked eye can be identified, the appearance of the product will be very different, usually counterfeit products in order to save costs will usually deduct materials and processes, the production of products are generally rough, the printing font is relatively blurred.

Multi-contrast. Before buying a belt, you can go to a number of repair shops or stores to inquire about ** and specifications, it is recommended to carefully compare these different ** products before making a choice. Advice to everyone:

The best way to deal with counterfeit products is to choose a formal purchase channel. Most of the genuine parts of automobile manufacturers are only sold through 4S stores to distinguish counterfeit and shoddy goods from the gray market, and are not sold through non-approved distribution channels. Therefore, it is best to choose the corresponding 4S shop when replacing the car belt.

Fault phenomenon: After using one end for a long time, the surface of the belt will be degummed, cracked and scratched.

Cause analysis: If the metal belt cleaner cannot be adjusted in time, it is easy to damage the belt, causing the rubber on the surface of the belt to fall off. The cleaner is not installed correctly, and sharp gravel can get stuck between the cleaners and damage the belt.

If the belt itself is not of good quality, it is more likely to have the above problems.

Treatment process: Once the belt has defects such as degumming, cracking, and scratching, it should be repaired in time. When the belt is damaged, the first thing to do is to solve the factors that caused the belt damage, such as the cleaner is damaged, the cleaner needs to be adjusted or replaced immediately, and then the belt should be repaired in time.

The belt damage is very small, and it can be repaired on-site with belt repair glue. When the damage surface of the belt is large or the local damage is serious, the locally damaged belt can be removed, a section of the belt can be replaced, and the vulcanizer is used for cementation. If the belt damage is not treated in time, and the damage spreads to the entire belt, it has no repair value and can only be replaced as a whole.

1. All fault phenomena: the aggregate is weighed and unloaded to the belt and the material is accumulated, resulting in the belt bulk material, or the aggregate conveyed on the belt is vacant, resulting in pebble bulk material.

Reason analysis: The sequence and time interval of unloading a variety of aggregates on the belt of the batching station can be adjusted at any time. The general unloading sequence requires that the aggregate that is discharged last is sand, and the unloading time interval is required to be that the tail of the former aggregate falling on the belt just coincides with the head of the latter aggregate falling on the belt.

If the time interval is too short, the former aggregate and the latter aggregate have overlapping piles, too much stacking will cause bulk materials, if the time interval is too large, there is a vacancy between the two aggregates, and if the former material is a pebble, it will roll on the belt and scatter down.

Processing process: 1. Adjust the discharging sequence of aggregate to ensure that the sand is the last discharge.

2. Adjust the unloading time interval of various aggregates according to the distribution of aggregates on the belt to ensure the continuous and uniform distribution of materials on the belt. The time interval is usually adjusted several times.

If the axis of the motor pulley is not parallel or misaligned with the axis of the mixing drum, the position of the motor can be adjusted.

The cement silo is the storage equipment of the concrete batching plant, and its specific installation location is next to the control building, so the following things should be paid attention to when installing:

1. During the installation process, it is necessary to pay attention not to tilt the silo body and deform the legs.

2. It is necessary to do a good job of wind protection and lightning protection to ensure the safety of cement tanks (silos).

3. The bottom of the outrigger and the foundation embedded parts must be firmly welded together.

4. The foundation must be firm and conform to the architectural design specifications.

5. It is strictly forbidden to strongly impact the outriggers and silo body of the cement tank (warehouse).

6. Regularly inspect and clean up the cement attached to the dust collector bag.

7. In order to prevent the occurrence of the cement tank (warehouse) burst accident, it is necessary to block the bag, and the pressure in the bag warehouse exceeds the safety pressure of the pressure safety valve at the top of the warehouse, and the pressure safety valve can be opened to release the pressure in the warehouse.

8. When the cement tank (silo) is working, it must be erected by a special crane, and then put on the pre-prefabricated concrete foundation, and check the verticality of the cement tank (silo) and the horizontal plane after it is erected, and then the bottom of the cement tank (silo) must be welded firmly with the foundation embedded parts.

You'll want to see if there's a problem with your belt connection, so it's causing this to happen, and then you need to fix this properly.

Replace the small drum to see if it is misaligned.

1. Let's analyze it first, under what circumstances does the surface of the drum slip and easy to adhere to the material is usually occurring?

First: the operating environment of the drum is relatively humid or even muddy, and the humidity in the operating environment is too heavy, resulting in the slippage of the drum;

Second: the selection of rubber plate is improper, and the anti-slip and wear-resistant performance is not enough to meet the on-site requirements;

Third: the transported material has more moisture, which penetrates into the surface of the rubber of the drum, resulting in slippage and adhesion of the material on the surface of the drum.

If it is said that the running material has too much moisture or the site environment is relatively humid, the construction personnel should try to ensure that the operation site is dry to a large extent, and the construction environment is drained and dehumidified, so as to increase the dryness of the belt running environment.

At the same time, in order to prevent the occurrence of slippage and adhesion on the surface of the drum, the construction personnel should try to choose the rubber plate with high anti-slip and wear-resistant performance for overmolding.

As we all know, the drum lagging rubber plate is generally divided into three kinds, namely RIT flat wear-resistant rubber plate, diamond-shaped wear-resistant rubber plate and ceramic wear-resistant rubber plate, in this case, the plane wear-resistant rubber plate is definitely not desirable, this kind of rubber plate grip is relatively weak, and it is more suitable for drum lagging treatment in a dry environment.

It is advisable to choose RIT diamond-shaped wear-resistant rubber plate or RIT ceramic wear-resistant rubber plate. Both types of rubber sheets have strong anti-slip and abrasion resistance, and can be used for drum lagging in wet environments. Of course, there is a difference between the two.

RIT diamond-shaped wear-resistant rubber plate has a pre-opened rubber groove on the surface, which can increase the sliding friction coefficient, effectively reduce the slippage between the drum and the conveyor belt, and protect the surface of the drum from adhering to the material, especially suitable for fabric belts and medium and high strength steel ribbon driving wheel lagging

The surface of the RIT ceramic wear-resistant rubber plate is embedded with a uniform aluminum oxide ceramic block, which can provide excellent grip between the driving rollers and the conveyor belt, and the rubber groove between the ceramic blocks ensures the maximum amount of drainage and mud discharge during operation. It is especially suitable for the lagging treatment of high-strength and high-tension conveyor belts, and can fully ensure the anti-slip and wear-resistant performance of the roller surface even in various extreme environments such as muddy, humid and high-wear environments.

Fault phenomenon: In rainy days, the inclined belt slips when the load is running.

Reason analysis: In rainy days, the moisture in the aggregate and the exposed part of the belt are easy to be wet, and the belt is wet, especially the inner ring is wet, which reduces the friction coefficient between the belt and the transmission drum, and reduces the torque torch transmitted by the drum to the belt, and when the torque is less than the torque required for the belt material transportation, the belt will slip.

Processing process: 1. Increase the counterweight of the belt tensioning device or tighten the belt adjusting screw rod to increase the positive pressure between the belt and the drum, so as to achieve the friction between the transmission drum and the belt.

2. Adjust the tensioning drum near the transmission drum to increase the wrapping angle of the belt on the transmission drum and increase the friction.

3. Cut the groove on the rubber layer of the transmission drum to increase the friction coefficient.

4. If the first 3 methods cannot be solved, the anti-slip roller needs to be replaced.

Such accidents are not work-related fatalities and are not included in the work-related fatalities assessment index.

Article 11 of Chapter II of the Regulations on Work-related Injury Insurance stipulates that in any of the following circumstances, it shall not be recognized as a work-related injury or treated as a work-related injury: (1) an intentional crime; (2) Drunk or taking drugs; (3) Self-harm or suicide; (4) Other circumstances provided for by laws and administrative regulations.

If there is sufficient evidence to prove that the worker committed suicide, then the employer will not deal with and compensate according to the work-related death standard, and at most give a little money for condolence and comfort based on humanitarian considerations. Of course, it all depends on the employer's idea to give more or less money.

Whether it is tight and loose at the same time, it will generally run to the tight side. If this is the case, there should be tensioning devices at both ends of the conveyor belt, and the loose side should be tightened, and if the tensioning device has been adjusted to the limit and is not tight enough, then try to loosen the tight side a little.

If one side is high and the other is low, it will generally run to the high side, at this time it depends on whether the equipment has a height adjustment device, if not, then you have to use your brain from the Qin section foundation.

The belt is reconnected on the street, and it must be cut vertically, and the other is to add a vertical roller on the side of the deviation, or called the anti-deviation roller.
