Hengshui Gucheng Self-lubricating Copper Sleeve Specifications and Focus Focus on Industry ZCuAl9Mn ZCuAl9Fe4. Aluminum bronze has high strength, high density and stable chemical properties. Commonly used in valve bodies, worm gears, nuts, pipe fittings, etc. Supply Hengshui Old City e. Riveting mold: It is to use external force to make the participating parts connect or overlap together according to a certain order and method, and then form a whole. The following are the application characteristics and advantages of self-bearings in the market: Good wear resistance, small friction coefficient and long service life. On average, Huaibei has many polluting industries such as steel, petrochemical, and thermal power generation. In addition, the number of automobiles has increased significantly in recent years, and a large amount of exhaust gas has filled the air with corrosive sulfide and nitride gases and particulates. These are the main reasons for metal corrosion. How much is easy, maintenance and repair. Copper processing mainly depends on his color, copper, copper is good copper. There is brass, the color head shines. There are copper-plated zinc, tin-plated, and white, which are inferior copper and copper impurities. They are bent down and broken by hand with black impurities. Hengshui Gucheng Self-lubricating Copper Sleeve Specifications and Dimensions Focus Industry Brass is an alloy composed of copper and zinc. Brass is divided into ordinary brass and special brass. High-strength brass belongs to the alloy material of aluminum brass. It has high strength and hardness, good wear resistance, and is widely used in bearings and bushes. The new product copper powder layer 0.2 ~ 0.35mm improves the bonding strength of PTFE / Pb and steel plate, and has good bearing capacity and wear resistance. At the same time, copper is a very good thermal conductive material, which can quickly transfer the heat generated during the operation of the bearing. Sales

Hengshui Gucheng Self-lubricating Copper Sleeve Specification and Size Focus on Industry The copper sleeve is an important component of various large and heavy machinery. The self-copper bushing is usually used in conjunction with the shaft. This can reduce friction during machine operation and at the same time give a large driving force to the mechanical equipment. Usually when the machine is running, the shaft is rotating and the copper sleeve is fixed. The friction between them generates a driving force, which increases the kinetic energy of the machine. At the same time, the repair and replacement of the copper sleeve is relatively easy, so the material selection of the copper sleeve is very important. Generally, a copper sleeve with a relatively soft material is selected, so that the friction of the copper sleeve and the shaft can reduce shaft damage. Steel back can be plated with a variety of metals and can be used in corrosive media; it has been widely used in various machinery parts, such as: printing machines, textile machines, tobacco machinery, micro-motors, automobiles, motorcycles and agricultural and forestry machinery. There are many mechanical parts that are required in many mechanical equipment, and there are many materials that can be used for copper parts. Hengshui Gucheng self-lubricating copper sleeve is a good manufacturer, and it is a kind of copper sleeve. So what are the characteristics of the phosphor bronze material used for the copper sleeve? The alloy process first preheats the crucible to dark red, and adds 20-40cm thick charcoal to its bottom. Hengshui Old City 57QSn4-3 tin bronze is tin bronze containing zinc. High abrasion resistance and good magnetic resistance, can withstand hot or cold pressure processing well; in the hard state, good machinability, easy to weld and braze, corrosion resistance in the atmosphere, fresh water and sea water it is good. Used for springs (flat springs, round springs) and other components, corrosion-resistant parts on chemical equipment, wear-resistant parts (such as bushings, discs, bearings, etc.) and anti-magnetic parts, and scraping for the paper industry. Potential development uses external control or internal control roll forming. . The sand box is a single-faced sand box with a suction chamber or a suction pipe, a hanging or walking sand box. The analysis project Huaihua solves: the pouring temperature of aluminum liquid is not higher than 670 ℃; reduce the sand core baking time, Hengshui Gucheng self-lubricating copper sleeve specification table, adhere to the strength of the sand core; set a reasonable holding pressure. Hengshui Gucheng Self-lubricating Copper Sleeve Specifications and Sizes Focus on the Industry Preheat the crucible to a dark red color and add the prepared flux. (Flux composition: 20% (mass percentage) of cryolite, 60% of sodium fluoride, 20% of calcium fluoride). Add the low-carbon thin steel sheet preheated to about 200 ° C and the regrind at the same time, stir the alloy after melting, and raise the temperature to 1150-1180 ° C. Add 0.3% phosphorous copper to deoxidize the alloy and add flux. Add pure aluminum and pure manganese preheated to 200 ° C (according to the ingredients) in batches. For each batch, use a stirring rod to melt it quickly and keep stirring to make the composition uniform. Then adjust the temperature of the alloy liquid. Between 1120-1220 ° C. Cover the slag with straw ash, adjust the alloy temperature (generally 1160-1200 ° C) according to the casting process card, and then quickly adjust the pouring temperature. Spot check copper / tin plating. product line

Hengshui Gucheng self-lubricating copper bushings have been focusing on the industry for a long time, increasing the high-temperature oxidation gettering properties of the alloy, and incomplete deoxidation is the primary cause of pores in castings. Improvement methods and results In summary, the primary reason for the occurrence of pores in aluminum bronze castings is due to improper chemical composition control and unreasonable technology. The following improvement methods are specifically formulated. It is determined that the chemical composition of the nut ZCuAll0Fe3 is AI: 5% ~ 5% ; Fe: 0% to 4.0%; Mn: 0.9% to 0%; the others are Cu. Gas degassing; refer to the essence of ZnCIz degassing in aluminum alloy, theoretically: 3ZnCI. + 2AI—ZAICI. Each 3ZnZn has a low boiling point, is easily vaporized at high temperatures, and jubilates in copper, and has outstanding degassing effects. Change the feeding order. In order to deal with the problem of severe overheating and oxidative gettering by adding AI or AI-Fe center alloy starting alloy liquid at high temperature, according to the principle of AI-Fe alloy, low melting point AI is melted first, and then high melting point Fe is melted to make it alloy. Quality standard copper / tin plating. Excellent service Because the shaft rolls over and the bearing pads are fixed, B090 bronze rolled bearings will inevitably occur during the rollover, and then the shaft and the bearing pads will wear out. There are many reasons for the surface of copper. Copper plants are not unified. how about it? We have analyzed copper castings for you. If you like our content, do not agree, I hope you can tell us, we will appreciate it! The selection of the position, use conditions and environmental conditions of the copper bearing sleeve, the use of Hengshui Gucheng self-lubricating copper sleeve, ensure the accuracy, and under the premise of ensuring the service life of the bearing and the feasibility of the bearing slewing ring and wheel bearing. This fault is really annoying. Once the copper sleeve of the fuel injector is damaged, the antifreeze will enter the fuel tank along with the diesel oil return line, causing the antifreeze and diesel to mix. If the separator is not forced, the fuel injector will be damaged. The high-pressure oil pump is just around the corner. Then how to quickly replace the copper sleeve of the injector. The copper sleeve is a wearing part in the automatic transmission. The copper sleeve is cheap and many maintenance personnel consider it to be a "low-tech" part. However, it has been proven in practice that if the role of the copper sleeve is not valued, "high-tech" failures will occur during maintenance, and maintenance quality will be difficult to guarantee. Each copper sleeve was spot-tested and subjected to a hydrostatic pressure test, and the pressure was radial sealed. The test pressure and time are strictly controlled by the copper sleeve hydraulic pressure microcomputer detection device. The test parameters are printed automatically. . Improve the quality of casting products, use high technology to achieve green casting, brand winning strategy, and broaden the market door.
