Seaweed fertilizer can increase the organic matter of the soil directly or through plants, and activate the activity of various beneficial microorganisms in the soil. These organisms act as catalysts in the "plant-microbe" metabolite cycle, increasing the biological effectiveness of the soil. Plant and soil microbial metabolites provide plants with more nutrients.

Seaweed is a natural biological agent that works in harmony with the soil ecosystem. It contains natural compounds such as sodium alginate, which is a natural soil conditioner that promotes the formation of soil aggregate structure, improves the pore space inside the soil, regulates the ratio of solid, liquid and gas in the soil, and restores the soil due to excessive burden and chemistry. The balance of natural colloid lost by pollution increases the biological vitality of the soil and promotes the release of available nutrients, which is beneficial to root growth and improve the stress resistance of crops.

Traditional chemical fertilizers have a single effect, and long-term use can lead to the destruction of soil structure. Seaweed is a natural seaweed extract that is harmless to humans and animals and has no pollution to the environment. It is listed as a special fertilizer for organic foods abroad. The products independently developed and produced by Beijing Leili Group Co., Ltd. have passed ISO9001 international quality certification.

　　 ISO14001 international environmental management system certification. Each product has more than 20 inspection points from raw materials, intermediate production links to finished products . The perfect quality control and traceability system ensures the stability of each batch of products.

 

 

Maglev centrifugal blower
Maglev centrifugal blower is a new type of high efficiency, energy saving and environment friendly blower formed by integrating magnetic suspension bearing technology and high speed motor technology into a traditional blower. Magnetic bearings are used to generate a magnetic field by means of an electric current and a magnetic field Generate suction to achieve the suspension shaft.High speed motor through the frequency conversion power supply to generate a frequency controllable alternating current input stator magnetic field to produce an alternating drive high-speed rotation shaft, that is, synchronous permanent magnet motor with the shaft together for high-speed rotation of the blower The impeller drives the air to enter from the air inlet of the volute and the air becomes a gas with a certain flow rate and pressure under the guidance and pressurization of the volute and finally bulges out from the air outlet of the volute.

What is the difference between Magnetic suspension centrifugal blower and air suspension centrifugal blower ?

1, the difference between the two is the use of different bearings, magnetic suspension As the name implies bearing using magnetic bearings, air suspension that uses air suspension bearings. The common denominator is that both types of suspension blowers adopt high-speed direct-coupled motors, frequency-variable speed regulation air volume and non-contact bearing technology, no lubrication system is required, no secondary pollution to the environment, high efficiency, low noise, Wide range of adjustment and other advantages.

2, but due to the special domestic air environment, air suspension bearings in the domestic environment, the higher the failure rate of operation, it is proposed to use resistant magnetic levitation blower. Here to talk about magnetic levitation, foreign companies engaged in the development and manufacture of magnetic bearings MECOS Switzerland, Switzerland, Canada REVOLVE company, Germany SEVNZ company, South Korea TURBORMAX company, the current German SEVNZ magnetic levitation fans and South Korea's TURBORMAX company's products in the international environmental field more Common, higher market share, if used, this should be the first choice. Although the cost of such a device is relatively high at one time, due to the saving in the construction process and the civil construction investment in the blower room and the power consumption and maintenance cost in the operation process, the overall life cycle cost of the entire project is taken into account. Blower with high economic efficiency, the aeration blower is the future development of the environmental protection industry's main direction.

How to choose a suitable Centrifugal Fan

    1, according to centrifugal fan performance curve to select the fan. This is one of the most basic and relatively simple method.

    2, the use of centrifugal fan performance table to select the fan, this method is the same as the use of pump performance table to select the pump, although simple and convenient, but can not accurately determine the fan unit operating conditions.

     3, Centrifugal fan performance selection curve Select fan This is the most commonly used fan selection method. Selection curve is the same series of similar, different impeller diameter of each fan of the total pressure, power, speed and flow relationship.

     4, Centrifugal fan dimensionless performance curve selection Fan fan dimensionless performance curve is a non-dimensional performance parameters that represent a variety of models, different numbers of fans. In order to narrow the choice of the first choice of fan speed.
