Casting elbow appearance
As the appearance of the welding elbow, then we say that the appearance of the casting elbow bar. Casting elbow appearance are fixed, of course, the general casting elbow appearance is according to different steel tube and to choose the different knowledge of casting elbow, so, in order to ensure the casting elbow appearance, usually Steel Pipe in the future, if not been yard rain washing off, then welding elbow after high temperature push general weld appearance of the elbow is appear out of the blue, of course, if the rain washed, we in high temperature after heating, heating welding elbow surface color are red. But overall, we guarantee tube is washed by the rain is very difficult, because is yard in summer is rain fog water washed, then push the system out of the welded elbow surface is red, too.

Radius of curvature. For example, the radius length is 1.5D, and the radius of curvature must be within the range of tolerances required. Due to these fittings, most used for casting, in order to improve the welding quality, end vehicles into the groove, leave a certain angle, side band, this requirement is quite strict, edge thick, at an angle of number and range of deviation provisions, geometric size than pipe much many. The surface quality and mechanical properties are basically the same as that of the tube. In order to facilitate welding steel, and the connecting pipe are the same. Fourth, is all the pipe fittings should be through the surface treatment, the inner and outer surface of the oxide scale through shot blasting, and then coated with anticorrosive paint. This is not only for export needs, in addition, in the country is to facilitate the transport to prevent rust oxidation, to do this work. Fifth is the packaging requirements, for small pipes, such as export, you need to do wooden, about 1 cubic meter, this provision in the case the number of elbows about not more than a ton, the standard allows the suit, large sets of small, but the total weight usually do not more than 1 ton. For large to a single package, like 24 "must be a single package. The other is labeled packaging, labeling is to indicate size, number, batch number, manufacturer trademark. In the pipe to be stamped on stamp, and attached to the packing list and the quality book file.
What do you have to know about the misunderstanding of agricultural machinery?
[China Agricultural Machinery Industry News] With the development of modern agriculture, agricultural mechanization has been deeply rooted in people's hearts, and the speed of "machine substitution" is also accelerating, but many farmers' traditional planting concepts have not yet been transformed. Farmers are still in a state of ignorance of agricultural machinery, so farmers must establish a correct concept of agricultural machinery.
What do you have to know about the misunderstanding of agricultural machinery?
The deeper the loose work, the better
Deep loosening is one of the important measures to promote conservation tillage. The depth of deep-slung work is determined by the layer of soil in the soil. Each area, even each plot, may be different. If the deep loose operation is too deep, the main hazard is that the deep and bad soil may be brought to the surface layer, which is not conducive to the growth of the crop; or the deep loose shovel is too deep and passes under the soil layer. Did not break the knot layer, the deep loose rod teeth like the knife to cut the tofu, cut through the knot layer, the deep loose effect is compromised. In addition, the fuel consumption of the tractor is greatly increased. Therefore, as long as the deep shovel can pass through the slab layer and break the slab layer, it is a reasonable depth of ploughing, not as deep as possible.
High-powered tractors must be "pressed"
The greater the power of the tractor, the greater the weight. It feels that the high-powered tractor is more "pressed" than the small tractor, that is, the pressure on the unit area of ​​the soil is greater. In fact, large-horsepower tractors mostly use two-wheel drive, or use radial tires with large grounding area, and some even use rubber track structure. The grounding pressure of high-powered tractors is likely to be smaller than that of small tractors. Especially after the use of wide-width and double-working agricultural implements, the number of tractors entering the ground is greatly reduced, and the "compacting" damage of the high-powered tractor on the soil is much lower than that of the small tractor.
Tractor is more important than farm tools
As long as the power level of the tractor is selected correctly, the main factor determining the quality of the agricultural machinery operation is the agricultural implement rather than the tractor. More and more people have found that the selection of tractors has been over-emphasized, and the selection of agricultural tools has not been taken seriously, which directly affects the economic benefits of agricultural machinery operators. In foreign countries, the price of some agricultural tools is close to or even higher than the price of tractors, which is unacceptable to many of us. At present, this situation is changing. There are several imported brands of agricultural tools that have been recognized by users. High-performance agricultural implements are at least twice as high in price as ordinary agricultural implements, and some even reach 2-3 times or more. The same level of high-powered tractors and advanced tractors are more expensive than ordinary tractors. Will not exceed 1 time. More and more people have realized that, to a certain extent, the choice of agricultural tools is more important than the choice of tractors, because the quality and benefits of work are often determined by farming tools.
Low price will definitely cost-effective
If you buy agricultural machinery, only use 1-2 years, it is likely that the price is low, which means high cost performance. However, agricultural machinery is not a general consumer product. For agricultural machinery with a service life of at least 10 years or longer, low prices do not necessarily mean high cost performance. There is an article on the Internet that says that Germans do not believe that "good quality and low price" is justified. China, which has basically realized agricultural mechanization, most people buy agricultural machinery is no longer a purchase, everyone will have their own personal experience, cost-effective products must be those with high quality and service level.
User is "God"
When the user chooses the agricultural machine, he regards himself as “God†and puts various conditions on the merchant (manufacturer or dealer), even those unreasonable conditions, such as excessive price reduction, etc., the manufacturer or the dealer is sold for sale. Forced to agree to the corresponding conditions. Once the sale is completed and the full amount is recovered, especially after the end of the warranty period, the manufacturer or dealer becomes “Godâ€, and the service requested by the user is slow, and the Spare Parts supply cycle is long and the price is extremely high. This relationship between the user and the merchant is incorrect and unsustainable. In fact, users and businesses, who are not "God", are an equal business partnership. The "strong" of either side will bring the ultimate "double loss" rather than a win-win situation.
Take your own money "full payment" purchase
The purchase of agricultural machinery, especially the purchase of large-scale agricultural machinery, users have to buy their own full amount, has become less and less. At the same time, merchants are subsidizing or subsidizing, but the profits are very high or the merchants are willing to bear the risks. Ordinary users will use bank loans, or through the merchant's rental company, to purchase agricultural machinery by installment payment. The sales of agricultural machinery are completed by the three parties through the cooperation of users, banks or leasing companies and merchants. The advantage of this is that the user can use the "leverage" to purchase the higher value agricultural machinery, the merchant will get a certain guarantee on the collection, the user owes the money owed by the user in installment payment is no longer the merchant, but the bank or lease the company's. The support of financial institutions such as banks and leasing companies has become an essential part of agricultural machinery sales, especially for large-scale agricultural machinery sales.
"Follow the wind" to buy agricultural machinery
If any agricultural machinery is too large in a certain area, it will bring about a reduction in the workload of a single machine and a decrease in economic efficiency. Especially for large-scale agricultural machinery with a value of more than one million, once the local quantity reaches saturation, there will be “supply side overcapacityâ€, and everyone’s economic benefits will decline. If then, planting structure adjustment or agricultural product price adjustment will occur again. Users who purchase agricultural machinery by installment payment will inevitably be "stressed" and worse. The purchase of agricultural machinery is investment, investment has risks, risks often come from the size and stability of the workload, must not be "follow the wind" to buy, must make rational thinking before making a decision.
"Agricultural Machinery Market"
There are a large number of "agricultural machinery market" in different places, which gathers a large number of agricultural machinery brands, which is conducive to users' "one-stop" purchase of a variety of products. The historical role played by the agricultural machinery market and the current real impact cannot be underestimated. However, with the popularity of automobiles and the Internet, and the popularity of special smartphones, the agricultural machinery market is no longer the only place where you can see and understand various agricultural machinery. More and more people are willing to learn more about the technical performance of a machine through the Internet, understand the specific word of mouth through the circle of friends, and even go to the field to understand the actual performance of the machine. Not long ago, according to reports, an internationally renowned company sold a 120-horsepower tractor through the rural Taobao platform of the Alibaba Group. Although the current popularity of this type of sales is difficult to say, at least it can be seen that some of the advantages of the traditional "agricultural market" are facing the challenges of the Internet. With the application of the O2O model in the agricultural machinery industry, the “agricultural market†will become less important and even disappear.
Agricultural machinery included in the subsidy catalogue is advanced
For some time, everyone thought that the products that can be included in the subsidy catalogue, after strict promotion and appraisal and review by relevant departments, must be good products, so that when some subsidized products are found, they are not technologically advanced. Users, or when there are quality problems, users will be very annoyed. In fact, the promotion of identification work is very specific, the workload is very large, a new product, to be able to enter the subsidy catalog and enjoy subsidies, it takes about 2 years. That is to say, the product technology in the subsidy catalog is 2 years ago or even earlier.
At present, the agricultural machinery products of some large-scale agricultural machinery enterprises at home and abroad have big technical improvements every year, and new products representing new technologies will be introduced. Therefore, it can be said that the current good agricultural machinery is not necessarily in the subsidy catalogue.
