Automobile belt is a kind of rubber product. With the increase of their working time, automotive belts and related accessories will wear and aging. Therefore, it is very important to correctly and timely understand the use status of automobile belts. Next, let's talk about how to identify the damage of the belt from the sound and appearance.

1.Listen to the sound to see if it's good or bad

When the belt squeaks, it generally means that the friction coefficient of the belt surface is greatly reduced, and the belt has been excessively worn. If there is a noise when the vehicle is under load, you may wish to observe one of the transmission belts, and you will find that the resistance or elasticity of the automatic belt tensioner or the belt elastic wheel will increase abnormally. When you hear the belt rumbling, it means the belt is shaking. This situation occurs generally because the drive belt is too loose and stretched too long, or the belt tensioner and elastic wheel are damaged.

2. Watch the belt change

The belt becomes longer: The first step to check whether the belt is normal is to check the belt tension. Use your fingers to strongly press the middle of the belt pulley. If the pressure is about 10kg and the belt reduction is about 10mm, the belt tension is just right. If the amount is too large, it means that the belt tension is insufficient. The cause of the insufficient tension may be that the fastening wheel is loose, or the belt has become longer. If the belt becomes longer, it means that the belt has been deformed and needs to be replaced in time.

Loose belt cracking: If the belt is found to have reduced hardness, abrasion, fiber breakage, cracks, burrs, etc., it indicates that the belt has been damaged and cannot be used.

Summary: Counterfeit and inferior belts will not only affect the normal operation of the engine and accelerate the damage of the vehicle, but may also affect the driving safety of the driver. Therefore, for our own safety, we must carefully discern when purchasing belts, compare them carefully, and must purchase them from regular automotive belt manufacturers. At the same time, in the daily use process, it should be timely maintained and discovered in time.

As an important part of the operation of the car, the belt is connected to various parts. Once it breaks or slips, the related air-conditioning compressor, power steering oil pump, alternator, etc. will be adversely affected. Therefore, it is very important to master the identification method of the automobile belt, and it is also important to know the replacement cycle of the belt. The following are some methods for identifying the quality of automobile belts and determining whether the belt is damaged.

How to identify the advantages and disadvantages of automobile belts?

1. Smell

True: No odor

False: There is a pungent smell of smelly gum.

Smelling is the first step in the identification of the advantages and disadvantages of automotive belts, and it is also a relatively effective trick. Often inferior rubber products will have a pungent smell of gum. The car owner can distinguish it with just a little attention.

2. Take a look

For the same reasons as above, counterfeit products usually make a fuss about materials and processes in order to save costs. The products produced are generally rough, and the printed fonts are relatively vague.

3. More comparison

A repair shop or store that sells counterfeit and inferior belt products will usually have the same specifications but several prices. It is recommended to make a careful comparison of these products with different prices before choosing.

Suggestion: The best way to deal with counterfeit and shoddy products is to choose regular purchase channels. The genuine parts of most automotive belt manufacturers are only sold through regular companies to distinguish counterfeit and shoddy goods from the gray market. Genuine products are not sold through unauthorized distribution channels. Therefore, it is best to choose the corresponding regular store when replacing the car belt.

With the rapid development of electronic information technology, the upgrading speed of electronic products is getting faster and faster. The production and sales of consumer electronics products, mainly flat-panel TVs, notebook computers, digital cameras, smart phones, and other products, have continued to grow, which has also contributed to the continuous growth of the consumer electronics connector market.

Once upon a time, the development of connectors in the field of consumer electronics was quite smooth, but with the maturity of consumer electronics technology and the increasing number of connector companies entering the consumer electronics industry, the market appeared to be in oversupply. Domestic connector companies, especially in the field of consumer electronics, have a fierce price war on connectors.

Not only that, with the USB TYPE-C interface occupying the market and the emergence and application of wireless technology, not only will most of the interface specifications be unified to reduce the interface, but also the connector technology on consumer electronics tends to be thinner and shorter Technically, a large part of domestic small and medium-sized connector companies have been eliminated. With shrinking market share, meager profits, and improved market access qualifications, the consumer electronics market is no longer as attractive as before.

Compared with the current consumer micro electrical connectors market, the industrial connector market has larger capacity and higher profits. At the same time, it has relatively more demanding military-grade connectors, and the market access qualification should be loose, which can meet most connector companies. Participate in competition. The country will vigorously develop the manufacturing industry, which is also good news for industrial connectors. Therefore, it is natural for domestic connector companies to turn their attention to the industrial connector market.

Seeking a way out in industrial connectors has become a coincident choice for connector manufacturers.

Sunkye is a global solutions provider of connector solutions and differentiated products to the world-wide interconnector industry.

visual inspection automation is equivalent to applying a camera in industrial robots. How does industrial robots use industrial cameras to achieve visual inspection?

1. Industrial camera is a key component of machine vision system. Its most essential function is to transform optical signal into orderly electrical signal. Choosing the right camera is also an important part in the design of machine vision system. The choice of camera not only directly determines the image resolution and image quality, but also directly related to the operation mode of the whole system.

2. The basic function of lens is to realize beam transformation (modulation). In machine vision system, the main function of lens is to image the target on the photosensitive surface of image sensor. The quality of lens directly affects the overall performance of machine vision system. The reasonable selection and installation of lens is an important part of the design of machine vision system.

3. The core of machine vision system is image acquisition and processing. All the information comes from the image, and the quality of the image itself is very important to the whole vision system. Light source is an important factor that affects the image level of machine vision system, because it directly affects the quality of input data and 30% of the application effect at least.

4. Through appropriate lighting design, the target information and background information in the image can be separated optimally, which can greatly reduce the difficulty of segmentation and recognition of image processing algorithm, improve the positioning and measurement accuracy of the system, and improve the reliability and comprehensive performance of the system. On the contrary, if the light source is not designed properly, it will lead to failure in the effort in the design of image processing algorithm and imaging system. Therefore, the success or failure of light source and optical system design is the primary factor to determine the success or failure of the system.

5. Image acquisition card is the interface of image acquisition part and image processing part. The process of converting an image into a digital image after sampling and quantization, and inputting and storing it into frame memory is called acquisition. The image acquisition card also provides the function of digital I / O.

6. The commonly used software of vision inspection includes Ni vision, Halcon, visionpro, opencv, MATLAB, etc., which are selected according to their own development needs.

Our company has best industrial robots. and understand the principle of industrial robot to realize visual inspection enables us know its value better and use its complex algorithm to produce for our industry. It can be said that robot visual inspection system promotes the development process of industrial network automation.

Pile foundation engineering construction method to improve the bearing capacity of soft soil pile driving engineering method. The effect of pile is to transfer the load of the upper structure to the deep soil layer on bearing capacity is bigger, also can adopt the method of compaction or squeeze real soft soil, increase the bearing capacity of the soil, so as to ensure the stability of the building, reduce the settlement. (One station foundation drilling .)

Pile foundation can be divided into two types: end bearing pile and friction pile.

The former refers to the pile through the soft soil and reach the rock or hard soil;

The latter refers to the pile hanging in the soil and bearing the weight by using the friction between the pile and the soil

The characteristics of

Pile foundation construction workload is large, generally a project to the construction of dozens to hundreds of piles, and often need to be completed in a short time, pile into more procedures, need to cooperate with more work.

Most of the construction sites are very limited, or even very small, while the site has more equipment and facilities, more materials and frequent movement of pore-forming and perfusion equipment.

When drilling holes with washing fluid, the site is not easy to dry and level, and the amount of slag discharge is large.

Because of the great fluidity of pile foundation construction, temporary erected lines are mostly used in the site, and municipal power supply is introduced as power and lighting.

The outdoor operation of pile foundation construction is greatly affected by the natural conditions, and the construction conditions are different from one project to another.

Rotary drilling rigs with GREAT Roller bit core barrel achieve high efficient works. If you drilling hard formation, GREAT made Core barrel with roller bit.

Well Drilling Bits

Well drilling is an engineering of rational exploitation and utilization of water resources in strata by using drilling equipment and technology.

Groundwater, on the other hand, is water that exists in cracks in the earth's crust or in gaps in the soil.

The various states of water buried below the surface are collectively referred to as groundwater.

The influence of water cut characteristics of different structures on well yield is as follows:

Clean sand and gravel sedimentary rock is the best source of water.

This kind of structure has strong water absorption, high water content and good water permeability.

Mixed layer of sand and gravel.

The sand and gravel mixture is also a water-yielding structure.

Because of the different proportions of sand, it is a secondary water-producing rock.

The lower the sand content, the higher the water yield.

Clay structure.

Although the clay structure holds water well, it is difficult for water to move through it.

This means that the clay structure does not flood the well so it is not an aquifer.

The sandstone.

It refers to the terrigenous clastic rocks whose grain size is 0.0625 ~2 mm and the sand accounts for more than 50% of all clastic particles.

If the clay ACTS as a cement in sandstone to hold the sand together it is a poor water-yielding rock.

Limestone.

It is an excellent source of water in all sedimentary rocks.

Limestone usually has large openings such as underground karst caves that contain high water content but poor water quality.

Basalt.

The earlier beds are dense rather than good water-yielding because they are tightly packed together.

If it's late it has spongy development it's a good source of water.

Of hard rock.

Such rocks as granite, porphyry, and other crystalline rocks are usually poor water producers.

The worst water-yielding beds are metamorphic rocks such as gneiss schist, quartzite, SLATE and soapstone.

In order to avoid the low efficiency of well drilling, the oil standard Tricone bit specification should be selected in the design of drilling diameter.

The selection of leading hole standard cone bit must be beneficial to the processing of reaming assembly cone bit in order to reduce the processing cost of bit.

The effect of drilling parameters on drilling efficiency is weight on bit.

The weight of bit should be determined according to the formation's hardness and softness. Meanwhile, the quality of bit, well bore, drilling tool, displacement, and performance of flushing fluid, equipment and power should also be considered.

Proper use of Tricone bit: select Tricone bit type to suit lithology requirements as much as possible, match bit size with drilling design, and use in order of size

In the process of using the bit, if the phenomenon of rampage occurs, the reasons should be analyzed immediately to check whether the formation changes or the borehole wall collapses.

The parameters should be analyzed and adjusted immediately. If the up-lift bit can't be drilled normally, the up-lift bit should be checked.

Analyze and judge the working condition of the well drilling head   in the hole.

In addition, measures should be taken to control well deviation, reduce the clearance between drilling tools and drilling holes, and play the role of full hole drilling and rigid anti-deviation.

In order to prevent deviation, centralizer and drill collar can be added on the top of the tricone bit.

GREAT water drill bit suppliers can recommend the right type according to your drilling demand. We provide water well drill bits for sale,welcome to buy our product.

On the one hand, the number of 5G base stations in China has increased significantly. 5G communication spectrum is mainly distributed in high frequency bands. The higher the frequency, the faster the signal attenuation, and the smaller the coverage area at the same power.

In the 2G, 3G and 4G era, the spectrum of China ’s three major operators is mainly distributed below 2.6GHz, and the spectrum of China Unicom and mobile in the 5G stage is in the 3.4-3.6GHz range. With the increase of frequency, the number of 5G base stations will increase significantly and is expected to reach twice the number of 4G base stations.

On the other hand, the demand for 5G also brings the technological upgrade of connectors. Under the characteristics of 5G low-latency and high-bandwidth transmission, the data transmission volume has been greatly improved, and the traffic density of 5G has been increased to 100 times that of 4G. With the miniaturization and integration of 5G base stations, the space occupied by the connector is further increased. Compression, electromagnetic interference and heat dissipation have also become important issues.

Therefore, 5G has higher requirements for the density, transmission rate, heat dissipation, electromagnetic interference resistance and reliability of the connector, and the value of the connector has been further improved.

With the increase in the number of base stations and the increase in technical requirements, the connector market is expected to grow significantly and enter a high-boom cycle.

According to the forecast of the Ministry of Industry and Information Technology of China, domestic operators' investment in 5G will be 1.5 times that of 4G, and the total investment will reach 1.5 trillion yuan. As for the pace of demand, with the start of 5G construction in 2019, the scale of 5G base station construction will also Will grow rapidly.
