Blackouts affect Chinese seal factory manufacture time and price from WONEPART Perhaps you have noticed that the recent “dual control of energy consumption” policy of the Chinese government, which has a certain impact on the production capacity of some manufacturing companies, and the delivery of orders in some industries has to be delayed. According to the understanding from the Chinese authorities, there have been two main reasons for China’s electricity consumption growth for a period of time. One is that economic growth has brought about electricity consumption growth. Since October, China’s economic growth has accelerated, and industrial production growth has reached a new high during the year. The growth rate of the added value of the industrial enterprises above designated size has exceeded the normal level before the epidemic, and external demand continues to be strong. The export growth rate hit a new high this year. Economic growth has brought about a rapid rebound in electricity consumption, which just confirms that China is the first to resume work and resume production fact.

The Mid-Autumn Festival, also known as Moon Festival, Moonlight Birthday, Moon Eve, Autumn Festival, Mid-Autumn Festival, Moon Worship Festival, Moon Niang Festival, Moon Festival, Reunion Festival, etc., is a traditional Chinese folk festival. The Mid-Autumn Festival originated from the worship of celestial phenomena and evolved from the autumn eve of the ancient times. Originally, the festival of "Jiyue Festival" was on the 24th solar term "autumn equinox" in the Ganzhi calendar. Later it was adjusted to the 15th of the Xia calendar (lunar calendar). In some places, the Mid-Autumn Festival was set on the 16th of the Xia calendar. Since ancient times, the Mid-Autumn Festival has had folk customs such as worshipping the moon, admiring the moon, eating moon cakes, playing with lanterns, admiring osmanthus flowers, and drinking osmanthus wine.

1. Comprehensive physical examination Before storing the hydraulic breaker, you should first conduct a safety physical examination on the hydraulic hammer breaker to check for malfunctions and loose screws and clean the whole hammer. 2. Replacing the rod seal can prevent impurities from contaminating the hydraulic system. Once the hydraulic breaker seal kits is broken, it is obvious that the breaker has oil leakage, and the operating pressure of the breaker may be insufficient due to internal leakage. Therefore, the small breaker needs to replace the seal kits when the working time is about 500 hours, while the large breaker needs to replace the oil seal between 300-400 hours of work, and pay attention to cleaning when replacing the hammer seal kits. Especially in winter, because of the cold weather, the sealing performance of the seal kits and diaphragm is not good, and more attention should be paid to the frequent replacement of the seal kits.

And continue to use in harsh environments such as stress, temperature resistance, oil resistance, and ozone resistance when the strength is greater than 100KG. Below, the characteristics of our fluorosilicone rubber are introduced in detail. Important characteristics of fluorosilicone rubber 1. Weather resistance, oil resistance, solvent resistance, and chemical resistance The main chain of fluorosilicone rubber is a Si-O bond structure, which is a saturated chain, so it has excellent air aging resistance. Its rubber test piece can still maintain good elasticity after five years of outdoor exposure test; after up to 10 years, Under ultraviolet light and harsh weather conditions, its physical properties have only minor changes. The tensile strength and elongation at break of samples placed in different locations have decreased by less than 25%. Compared with methyl vinyl silicone rubber, fluorosilicone rubber has excellent oil resistance, solvent resistance, and chemical resistance; even when compared with fluororubber, it has good oil and solvent resistance. After immersing in the same medium, temperature and time, it shows excellent durability. Fluorosilicone rubber has better resistance to methanol-containing gasoline. Even in a gasoline/methanol mixture, the hardness, tensile strength, and volume change of the vulcanized rubber are very small. After a long-term immersion test for 500 hours, the physical properties are also almost no change at all. 2. Heat resistance Compared with fluororubber, fluorosilicone rubber has excellent heat aging resistance, especially the retention rate of physical properties at high temperature. Compared with silicone rubber, fluorosilicone rubber reduces the heat resistance of fluorosilicone rubber to a certain extent due to the presence of trifluoropropyl group. The reason is that trifluoropropyl group is easily thermally decomposed, and the decomposition produces highly acidic compounds that accelerate fluorine. Thermal aging reaction of silicone rubber. The high temperature decomposition of fluorosilicone rubber is the same as that of silicone rubber, namely: side chain oxidation, main chain rupture, side chain thermal decomposition and various compound reactions. Since the decomposition products can also cause the main chain to break, the heat resistance is usually worse than that of silicone rubber, and it has begun to oxidize and age at a temperature of 200°C. Temperature has greater influence on fluorosilicone rubber than silicone rubber, but less than fluoroelastomer. Foreign countries have also studied the service life of fluorosilicone rubber at 150℃×2000h, 175℃×5000h, and 200℃×4000h. The result is second only to methyl vinyl silicone rubber. 3. Low temperature performance Like ordinary silicone rubber, fluorosilicone rubber has good low temperature performance. Since fluorosilicone rubber is a linear polymer composed of soft Si-O as the main chain, its low temperature characteristics are better than those of fluoroelastomers with C-C as the main chain. First of all, the molecular backbone of fluorosilicone rubber is relatively flexible, giving it excellent cold resistance. Secondly, the molecular chain of fluorosilicone rubber is in a helical configuration. The flexibility of the molecular chain is greater than that of the CC bond or the Si-C bond. The interaction force between the molecular chains is weak. These structural features make it soft and elastic. When it changes, the intermolecular force changes very little, so its various properties, especially elasticity, change little, making it have low-temperature performance that other rubbers can’t match. Third, the presence of trifluoropropyl substituted methyl can destroy the regularity of the polydimethylsiloxane molecular chain, reduce the crystallization temperature and degree of crystallization of the polymer, and make fluorosilicone rubber have a better low temperature than silicone rubber Sex. Therefore, fluorosilicone rubber still has elasticity at a low temperature of -60°C to -70°C, and can be used for a long time at -60°C. 4. Electrical insulation and radiation resistance The electrical performance of fluorosilicone rubber is similar to that of ordinary silicone rubber. Except for high frequency and high voltage electrical environment, its electrical insulation performance can reach the use level. The electrical insulation performance changes little under severe conditions such as high temperature, low temperature, humidity, oil, solvent, chemicals, ozone, etc. The radiation resistance of fluorosilicone rubber is not outstanding, but the radiation aging resistance is better than that of methyl vinyl silicone rubber. 5. Physical and mechanical properties Like ordinary silicone rubber, fluorosilicone rubber has relatively low mechanical strength (especially tear strength). Our company can customize and process fluorine-silicon special-shaped parts, O-rings, gaskets, gaskets, oil seals, etc. according to requirements. After customer experiments, the effect is excellent. Welcome customers in related industries to exchange and consult, and request samples for testing.

O-ring is a sealing element with a circular cross-section. In the mid-nineteenth century, some people used O-rings made of cast iron as the seals for steam engine cylinders. Later, natural rubber was used for faucets. With the development of rubber production, O-rings are currently made of synthetic rubber. Practice has proved that the sealing performance of the O-ring is very good, so it is used in equipment from airplanes to general hydraulic and pneumatic equipment. In this page, we will introduce the function of O ring in did

An engine is a machine that can convert other forms of energy into mechanical energy, including, for example, an internal combustion engine (gasoline engine, etc.), an external combustion engine (Stirling engine, steam engine, etc.), an electric motor, and the like. For example, internal combustion engines usually convert chemical energy into mechanical energy. There are many cases happen to engine, for wonepart we have experience of engine repair and rebuild projects, if your engine have the following problems, then you will check the following reasons as reference: 1. When the start switch is engaged, the engine crankshaft will not rotate Possible reason • Battery output is too low • Defective wire or switch • The electromagnetic switch of the starting motor is faulty • The starting motor is faulty • Intrinsic problems affecting the rotation of the engine crankshaft 2. Start the motor crank, but the engine cannot start Possible reason • No fuel in the fuel tank • Poor fuel quality • The fuel filter is dirty • The fuel pipe is dirty or damaged • Low fuel pressure • There is air in the fuel system • The fuel system and engine are not at the correct timing • The exhaust valve is always open (the fuel does not have high enough pressure to start the engine) • Turning speed is too low • No fuel in the fuel injection pump housing

Here-comes-the-bearing-disassembly-non-destructive-disassembly-any-bearing-can-be-dismantled-like-this! There is all kinds of hydraulic pump and parts, engine and parts need to use bearing, and we could supply all kinds of bearing for you. However, when you have problems, how to dismantle in non-destructive way.Reasonable disassembly of the bearing in the case of interference fit is the core of bearing disassembly technology. When the disassembly force is so large that it cannot be dismantled by ordinary methods, and the disassembly force produced by conventional methods is likely to damage the bearing, an oil hole is generally designed at the end of the shaft, the oil hole extends to the bearing position and then penetrates radially to the shaft surface An annular groove is added, and a hydraulic pump is used to pressurize the inner ring to expand the inner ring during disassembly to reduce the disassembly force. For small bearings mounted on adapter sleeves with straight shafts, a hammer can be used to remove small steel blocks that evenly act on the end face of the bearing inner ring (Figure 7). For bearings mounted on adapter sleeves with stepped shafts, the use of hydraulic nuts can make bearing removal easier. After the bearing has been running for a period of time, there will inevitably be needs for maintenance or damage replacement. In the early development of the machinery industry, the popularity of professional knowledge was insufficient, and the awareness of safe operating procedures was insufficient. Today we will only talk about the disassembly of bearings .

NOK Original Seal from WONEPART,NOK seals are important mechanical parts that prevent the lubricant, water, liquid chemicals and gases on the machine from leaking out of the gap, and at the same time prevent sand and dust from entering from the outside.

The step seal is composed of a rubber O-ring and a polytetrafluoroethylene ring. The material is PTFE + NBR. In special cases, the rubber elastomer nitrile rubber NBR uses fluorine rubber FKM. It can be divided into step seal for hole and grid ring for shaft, but its sealing effect is the same. According to its own deformation, it will produce higher initial contact stress on the sealing surface and prevent the leakage of pressureless liquid. When the hydraulic cylinder is working, the pressure liquid passes through the elastic deformation of the O-shaped sealing ring to squeeze the square sealing ring to the greatest extent, making it close to the sealing surface, which produces a higher additional contact stress that increases with the pressure of the pressure liquid. Together with the initial contact stress, the leakage of pressure liquid is prevented.

The guide ring or wear ring is mainly used for guiding, and is mainly used for guiding the piston and piston ring in hydraulic cylinders and cylinders, and plays a supporting and guiding role.Guide ring, guide sleeve, support ring, retaining ring, L retaining ring, phenolic cloth guide ring, bakelite electric ring, washer, guide belt.
