Submersible pump outer cylinder anti-corrosion technology to solve the problem

Electric submersible pump is one of the important means of long-term stable production in oilfield, but the problem of failure of electric submersible pump in oilfield production is very common. The survey found that the failure rate of ESP due to corrosion of the electric submersible pump outer cylinder varies from 4% to 83% of the total electric submersible pump well with the different oilfield conditions. Submersible pump electric submersible pump down to the depth of 1000-2500 meters, directly immersed in oil, natural gas, water and a certain amount of mixed sand medium. Mixed media pressure of 12-25MPa, the temperature is generally 50 ℃, 90 ℃, 120 ℃, 150 ℃ several levels. In this environment, electric submersible pump outer cylinder not only produce chemical corrosion, electrochemical corrosion, but also wear phenomenon. The specific causes of corrosion and wear are as follows: 1. The existence of Cl, H2S and CO2 in the mixed media makes the oil layer have special corrosion properties, directly threatening the service life of the outer cylinder of the electric submersible pump. H2S corrosion may be the most detrimental to the electric submersible pump outer cylinder. The corrosion product and the electric submersible pump outer cylinder form a corrosive battery when they are in direct contact. The electric submersible pump outer cylinder as the anode is rapidly corroded; corrosion products and salt if long term Deposition of the pump barrel will not be cleared, will lead to corrosion of the outer cylinder intensified; when the crude oil moisture content of more than 80% -90%, the corrosive nature of the reservoir liquid also increased sharply. 2. The hydraulic impact on the outer cylinder surface of the submersible pump further aggravates the formation and collapse of the crude oil bubbles on the surface of the submersible submersible cylinder which becomes hot and increases the degree of corrosion and wear of the outer cylinder of the submersible pump. In addition, Vibrations can cause fretting wear between the pump barrel and the casing. Practice has proved that in corrosive media, even the tiny vibration of the pump outer cylinder will cause severe wear of the pump outer cylinder. There are two ways to solve the above problems: First, the use of special materials to adapt to various well conditions, the replacement of the original outer tube material, this method is feasible but costly, not easy to promote. Second, select the appropriate surface treatment technology and surface coating materials to cover the surface of the electric submersible pump outer cylinder to prevent corrosion and wear. This method is low cost and works well, and with the development of materials and surface engineering techniques, more and more materials and surface treatment processes are put into use to better meet the increasingly demanding use of surface coatings. Submersible Pump Workflow Beijing Andonger Engineering Co., Ltd. New Materials Branch from the material design point of view, the development of the AOC-240 alloy as the core of the ESP electric cylinder anti-erosion new technology. The technology is the use of thermal spraying method AOC-240 material sprayed on the outer surface of the electric submersible pump to obtain a layer of about 0.2 mm thick, that is corrosion-resistant and has good wear resistance of high-alloy coating. The coating has the following characteristics: The coating has excellent corrosion resistance under various well conditions; Strong bonding strength between the coating and the substrate; Good anti-fretting wear resistance; Good coating Oil and water resistance and anti-scaling performance; coating has excellent heat resistance and thermal conductivity. The use of this technology to deal with the submersible pump greatly enhances the outer tube of the electric submersible pump corrosion and wear resistance, so that the service life of electric submersible pumps increased by 10 times. At present, electric submersible pumps with AOC-240 coating are widely used in oil fields such as Daqing, Bohai, Liaohe and are well received by users.

LED Hydroponic Light

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.

Applications

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.
