Impurity pump is used to transport the liquid containing solid particles, pump over-current components required corrosion resistance, in order to prevent clogging of the solid phase crystal, impeller blades less, usually between 2 to 8 pieces. Pump often uses a wider flow path. In order to prevent the solid particles from entering the shaft seal and preventing the inflow of outside air, the shaft seal adopts a clear liquid as the seal liquid and the shaft seal structure is required to be reliable. Pump speed is generally not high, usually 1000 ~ 1500r / min. Correspondingly, the pump is also less efficient. First, the impeller and pump design General impurities impeller pump with parallel cover, the slurry into the impeller at the exit from the center to both sides of the formation of external vortex, so that the front and rear impeller cover and lining serious wear and tear, which is caused Overcurrent components of the main short life reasons. Warman pump design impeller outlet at the concave, so that both sides of the impeller on both sides of the front and rear cover at a speed greater than the middle speed, the slurry at the exit into two streams of fluid, to the center of rotation, forcing the particles flow to the center caused by spiral whirlpool, So that both sides of the concentration is reduced, thereby reducing the pump body flow path and both sides of the wall wear. Second, the seal centrifugal impurities Pump packing seal, vice impeller seal and mechanical seals and other forms of shaft seal. Vice-impeller seal is the biggest advantage of reliable operation, but in the design requirements of the impeller inlet pressure control in a certain range, the Warman pump provisions should be less than 10% of the pump outlet pressure. This form of shaft seal shaft seal water, but the use of vice impeller will increase power consumption, usually about 5% of rated power. Vice impeller must be used in conjunction with the parking seal, parking seal is also commonly used for the packing seal. Packing seal cheap, high reliability, but in the delivery of liquid containing solid particles, must seal seal water rinse. General seal pressure equal to the pump outlet pressure plus 35Kpa. Although the mechanical seal is a widely used form of sealing, some problems can not be solved temporarily in order to prevent the solid particles from entering the friction pair and the choice of the friction pair material. In most applications, the effect is not satisfactory. From the introduction of foreign Phosphoric acid equipment used in the shaft seal, seal and eccentric block parking seal, the operation of the impeller blades, impeller are rotating, the liquid in the centrifugal force to form a liquid ring, the Vice impeller hub at a negative Pressure, the liquid will not leak. At the same time, the centrifugal block opens like an umbrella under centrifugal force, pushing the actuator to produce axial displacement. So that the seal ring and static seat off, the static seal does not work, but the spring is compressed. When the pump is stopped, the centrifugal block is reset, and the actuator, the seal ring and the static ring seat are in close contact with each other under the action of the spring force, so that the static seal is closed to seal the liquid and the liquid is not leaked. Although the shaft seal device consumes power, the pump efficiency is reduced by 1% ~ 2%, but it allows a larger sealing gap, which can be leak-free when sealed with a medium containing solid particles, and has a long service life and a sealed reliable. Third, the material impurities Pump overcurrent components can be used more materials, should be based on the physical properties of the slurry delivery (particle composition, particle size, shape, hardness, concentration, etc.) and chemical properties (acid, alkali, oil) may be. The results show that the wear rate of metal is proportional to the velocity of solid particles (abrasive particles). The wear rate of metal increases with the size of abrasive particles. The wear rate of the metal also increases with the hardness and concentration of the abrasive grains. For highly corrosive slurry, you can choose other stainless steel, such as 304,316 and 20 alloy, etc., to be resolved with the pump plant. Fourth, the drive mode Impurities pump drive direct connection (flexible couplings, hydraulic coupling) and indirect transmission (V belt, reducer), in addition to frequency control devices and SCR devices through speed. One flexible coupling and V belt drive disassembly convenient, cheap, can be preferred.
LED Grow Lights
LED grow lights are relatively new to the cannabis growing scene,but they have become wildly popular over the last few years with their ability to produce great yields while staying cool and using a reasonable amount of electricity.
Choose LED grow lights if...
You want to use the most cutting-edge indoor cannabis grow lights with a customized spectrum of light
You are willing to do some research to determine the best LED Grow Light for your space
You have some extra money to spend on your initial setup (some of the best LED grow lights are expensive!)
Quality (potency, smell, trichome development) is more important to you than yields/watt.
You don't want to deal with an exhaust system or ducting,and would prefer to just hang your grow light over your cannabis plants and let the lights cool themselves

Cautions:
1.Do not use the lights in dripping water or anywhere where they will get wet, water and electricity can be a dangerous mixture
2. The working environment for the light is -20~40 degree celsius,45%RH~90%RH.
3. To protect the light, Plz cut off the power when there is a lightning strike.
4. Don`t touch or move when the light working.
Suggestions:
1.Clean the dust inside every 6 months to ensure the good heat dissipation and long life time.
2.Don`t keep too short distance to the plant canopy to avert leaves bleaching.
3.Highly hang the lamp will weaken the energy and affect the growth cycle of the plants, so the lamp should not be hang too high.
4.While taking care of the plants, please spray the leaves and branches 2-3 times everyday, to ensure the plants do not wrinkle a wither, and have no phenomenon of few fruit, and hard pericarp.
Philizon have over 6 years' experience in designing and manufacturing led grow lights and LED Aquarium Light. Persuiting to offer the best LED grow lights for plants growth,we cooperate with the scientific research institutes and the Academies of Agricultural Sciences in USA, Australia Canada, UK and so on.A great number of commercial plant growers test the lights, and their feedbacks show that this lamp owns a lot of 640nm,660nm and 740nm lights, which gives the plants enough nutrient in the flowering and fruiting phase and bring a far higher yield than other led grow lights in the market.
