[China Aluminum Industry] bushing heat treatment process:
The shaft sleeve is one of the main parts of the gear pump and is mounted on both ends of the high-speed gear to support the bearing. It must have sufficient strength and good abrasion resistance. In order to ensure the performance requirements of the parts, our factory adopts non-standard aluminum-tin alloy. The role of Cu is to strengthen the matrix. Sn forms a softer, low-melting Al-Sn eutectic, increasing wear resistance. The original heat treatment process is 515 °C solid solution 6h water cooling, 180 °C aging 8h air cooling. There are two problems with this process:
(1) The Al-Sn eutectic was over-fired to add tin to form a tin-containing 99.5% Al-Sn eutectic with a melting point of 229°C. When the workpiece is heated to 515°C, the Al-Sn eutectic is overheated and the complexed pellets are formed when quenched and cooled. In the process of forming complex melting pellets, on the one hand the grain boundary is oxidized, the grain strength is reduced, and on the other hand many microscopic voids are generated, so that the grain interface energy is increased, the strength of the metal is reduced, and it is easy to use during use. Premature failure.
(2) Long process production time, up to 16 hours, low production efficiency, and high energy consumption.
From the metallographic observation and mechanical performance test data can be seen, 250 °C × 7h treatment process is ideal. The Al-Sn eutectic is distributed along the grain boundary in a discontinuous network. On the one hand, the distribution of the Al-Sn eutectic is uniform and ensures good wear resistance. On the other hand, the Al-Sn eutectic does not divide the matrix, making the alloy better. Plasticity and toughness. Using 250 °C × 7h treatment process can get higher hardness, because the alloy contains less Cu, metal mold cooling speed, in the casting cooling process, has ensured Cu melted into the solid solution, played a quenching effect. This has also been demonstrated by increasing the hardness through natural aging. The tensile strength of air-cooled process at 250°C×7h air-cooling process is higher than that of 515°C×6h+18°C×8h air-cooling process by 47%. The air-cooling process temperature of 250°C×7h is slightly higher than the melting point of the Al-Sn eutectic, in order to obtain a discontinuous distribution of the Al-Sn eutectic through a short holding time without overheating the eutectic. On the basis of the process tests, a small batch (400 pieces) of trial production was carried out. After the hardness, metallographic examination, and test of the product on the test bench, all were qualified. The process was put into production in 1996 and has produced hundreds of thousands of shaft sleeves, all of which are qualified. The ergonomics increase by 1.3 times, saving about 70,000 yuan a year and saving more than 80,000 kW.h.
Now that you know why having the best LED Hydroponic Light is the most effective way of growing plants indoors, it is important to know what exactly you should be looking for in a model before purchasing it. Even though LED Grow Lights overall consume less power, provide more useful light, and give off less heat, there are still poor models that wouldn't give you everything that you are looking for in a set up. By taking a look at a few things, though, you'll be capable of having the best harvests ever and making sure you are saving money and able to truly enjoy the fruits of your labor.
LED Grow tube light uses the new light spectrum optimized horticulture SMD LEDs for higher yields and lower operating costs compared to standard horticultural T8 and T5 fluorescent light fixtures.Ideal lighting for Micro greens, lettuce and seedlings, the low profile light tube allows for a great utilization of growing space while reducing the cost and maintenance of LED drivers.
How to Select the Best Grow Light for your Greenhouse?
The plant needs light to thrive cause the light is essental for photosynthesis.without it,plants can not make food.but light can also be too intense,too hot or last too long for growing healthy plants.plant growth accelerates with abundant light because more of the plant`s leaves have exposure,which means more photosynthesis.in the winter,days are not long enough,but many plants still need 12 hours or more of light per day.
Now,adding led grow lights to your greenhouse is an nice choice if you live in the north, and can not get enough daylight in winter.you might be take HID into consideration,cause it has high output and cover a wide area.but now,we providing you some dfferent.the newest type of grow lights use LED technology.
Provides Maximum Light Density and optimizing spectrum(410nm-740nm,white)
as we know that the plants need more light from the blue side of the spectrum during their seedling stage and when developing foliage and require light from the orange to red side of the spectrum while inblooming and fruiting phases. We adopting lastest intergrated COB technology, white , more red and blue PAR(410-740nm) per Watt than any other lighting fixture for the best color uniformity.
Dual Veg and Bloom for plant growth and bloom
the Led grow lights feature selectable VEG and BLOOM light spectrums to deliver maximum performance from seeding through the flower stage and finally harvest.
Increase yields and potency
using high quality lense that hyper-focus the lights on your canopy.the photons are beamed directly to the plants.this gives growers the ability to get greatest possible crop yield.
Reduce your costs with energy efficiency
energy-efficient cannabis grow lights cost between 40%-60% less to operate compared to HID lam year.
Led grow light also eliminate the needs for ballasts and reflectors while they minimize the cooling systems,accelerating your payback.you will see the electrical bills trimmed by approximately half,year after year.
Installs and operates simply
the input voltage is AC100V-240V,fit for the world standard,built-in power supply.do not need other equipment,just access to the Plug,the lamp will be work smoothly. The led grow lighting is small size,just few inches and easy to install.it is the good option for some greenhouse.
Long lifespan
using built-in quiet fans and the shutter in the wind,induced draftfrom all sides.runs with quiet. Useadvanced isolation power supply and soft start protection technology, to prevent the high voltage when turn on the light from damagingthe lamp body.
Latest Diamond Version LED Grow Light for plants,using effective full spectrum 360-870nm sunlight spectrum for plants,largely accelerate the plant growth.Compare with the previous led grow lights,Diamond LED Grow Light use high par value and high lumen ligthing for the plant growth.Solid lamp body can last for long time.It can be used to enhance the growth of different plants (medical plants, vegetables, herbs and flowers ).Widely used in hydroponic,greenhouse, indoor garden, horticulture, aeroponics.It is suitable for all plants growth.
Usage Instruction:
Extremely bright,do not look directly at the LED grow light when the light is working.
Indoor use only,not water-proof.no extra ballast is needed.
This light includes IR(infrared)LEDs which look dim/invisible,they are not faulty LEDs.
Timer controls both channels on/off together.cannot turn VEG and BLOOM channels on/off separately.
