Technical guidance: use and maintenance of agricultural submersible pumps

During the slack season, the submersible pumps should be properly maintained to prolong their service life and ensure normal use during busy hours. 1. Check wearing parts: The submersible pump impeller, retaining ring, bushings and bearing seat are all wearing parts. First of all the pump should be removed, check the wearing parts are intact. Do not use damaged or unqualified parts. 2, replace the oil: respectively, open the seal chamber and the motor oil hole screw inside the sealed chamber and the motor all the internal release of lubricating oil, replace the new oil, to ensure the normal lubrication system work. 3, the demolition of the pump casing rust: spring before use, should be disassembled the pump casing, turn the impeller and then start to prevent rusting parts can not start normally and burn the motor. This maintenance is especially important for water filled motors. 4, to ensure that the seal: agricultural submersible pumps on the sealing requirements are very strict, in the replacement of sealed room lubricants, if you find the oil cloudy and high moisture content, you must replace or replace the entire seal box or seal ring to ensure that the seal Good performance. 5, dry the motor: Use 500 megohms table to measure the insulation resistance of submersible pump windings and the shell, if the resistance is less than 0.5 megohms, you should get rid of the motor moisture. Drying methods are: external drying method, current drying method and the combination of both at the same time dry. External drying method is the use of external heat source for processing, commonly used measures are: ⑴ hot air: the use of electric heater blower (small submersible pump available hair dryer) hot air blowing to achieve the purpose of drying; ⑵ bulb baking: Closed box, the use of several 200-watt light bulbs for baking. Note that the baking temperature can not be too high, should be controlled below 125 ℃; ⑶ current drying: According to the submersible pump impedance and power supply size of the motor windings in series or in parallel, and then access a variable resistor, adjust the current About 60% of the rated current value, power and dry. 6, to ensure bearing lubrication: water-filled submersible pump should check the replacement of the upper and lower end of the bearing housing skeleton oil seal and lithium-based grease. To ensure long-term bearing lubrication in good condition. 7, check the bearings: Check the motor part of the upper and lower bearings, if found to wear or clearance is too large, must be promptly replaced with new bearings, non-sick "improper use. Check the method is as follows: If the motor is running, resulting in "carbazole" sound, and the cycle and the speed is proportional to, and feel trouble by rotating the rotor, the bearing raceway is a bit astringent or avulsion phenomenon; If the bearing intermittent The "哽 哽" sound, turning the rotor by hand when there is an indefinite dead, the ball is generally broken, the inner ring broken ball or broken. In the event of these circumstances, the bearings must be replaced to avoid further damage.

Indoor LED Grow Light

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.
