Fertilizer raw materials refer to substances that can supply nutrients needed for crop growth and development, improve soil properties, and improve crop yield and quality. It is an important means of production in agricultural production. Generally divided into organic fertilizers, inorganic fertilizers, biological fertilizers. It can also be divided into farmyard fertilizers and chemical fertilizers by source. According to the amount of nutrients contained, it is divided into complete fertilizer and incomplete fertilizer; according to the characteristics of fertilizer, it is divided into direct fertilizer and indirect fertilizer; according to the components, it is divided into nitrogen fertilizer, potassium fertilizer, trace element fertilizer and rare earth element. fertilizer. Fertilizers are essential for increasing crop yields, and the lack of any element affects the normal growth and development of crops.

What are the performance characteristics of EQWQS high flow submersible pump?
EQWQS large flow submersible pump uses a unique double-suction double-flow channel structure, EQWQS new high-flow submersible pump unique design completely solve the submersible pump axial tension at high lift occasions the use of mechanical seal easy to leak specialty. Now to introduce the performance characteristics of the EQWQS high flow submersible pumps have what. Large flow submersible pump EQWQS large flow submersible pump Product Features 1, EQWQS large flow submersible pump is a submersible motor for the double suction pump ingenious combination, it not only has the function of submersible pumps and double suction pump efficient and stable operation Special performance. 2, EQWQS type energy-saving double-suction submersible pump can reach the requirements of the use in the price of high-lift occasions, lead mechanical seals in negative pressure operation, with higher reliability and durability. Mechanical seal with dual series sealed, made of hard and wear resistant tungsten carbide, PTFE seal ring, with wear-resistant, corrosion-resistant, durable and so on. 3, EQWQS new submersible pump uses up and down the water absorption structure of fine liquid level is low, the use of double suction dual flow structure, the motor without axial tension, reduce and balance the radial force, greatly improving the life and efficiency of submersible pumps. 4, high-flow submersible pump anti-clogging structure design of large runner, greatly improving the debris through the ability to effectively through the shorter fibrous material and smaller diameter solid particles. 5, high-flow submersible pump compact structure, small size, easy to move, without the pump room, submerged in liquid can work, greatly reducing the project cost. 6, large flow submersible pump oil chamber resistance to set a leak probe, when the pump side mechanical seal damaged water into the oil chamber, the probe sends a signal to implement the protection of the pump. 7, the flow of submersible pumps can be equipped with automatic safety control cabinet according to user needs, the pump leakage, leakage, overload and over-temperature monitoring, put the pump to ensure reliable and safe operation. 8, EQWQS submersible pump dual rail automatic coupling installation system, to the pump installation and maintenance has brought great convenience, maintenance personnel do not have to access the sewage pool for maintenance. 9, the float switch can be based on changes in water level required to automatically control the pump start and stop, without personnel care. 10, the new submersible pump configuration outside the circulating water device, long-term work at low water levels. 11, high-flow submersible sewage pump configuration automatic mixing device that can stir the sediment in the sewage pool, so that sewage sludge mixed with the pump. 12, energy-saving submersible pumps can be selected according to user needs mobile installation and fixed automatic coupling installation of two options.
