Corrosion-resistant submerged pump is widely used in petroleum, chemical, textile, rare earth, agriculture and other fields. The anti-corrosive submerged pump relies on the movement of the piston and relies on the atmospheric pressure to press the water up. A wide range of corrosion-resistant submersible pumps make the corrosion-resistant submersible pump a very competitive advantage in the pump industry. Next, we will introduce it in detail through the introduction and characteristics of the anti-corrosive liquid pump. Introduction and characteristics of anti-corrosion liquid under the pump Anti-corrosion liquid under the pump is to raise the water pressure by atmospheric pressure. By virtue of the movement of the piston, an approximately vacuum is created and the external atmospheric pressure forces the water up. From the principle can be divided into pressure pump, centrifugal pump, axial flow pump, mixed flow pump, screw pump and so on. Corrosion-resistant liquid sub-pump classification can not be integrated into the working principle and purpose of classification, it will be chaotic. Purpose is to use, the principle is the principle, different principles of the pump can be used in the same purpose. The same pump can also be used for different occasions, can be used for different purposes. For example: The mixed flow pump is a diagonal flow pump, which uses a mixed flow impeller, that is, the liquid flows out of the impeller in a direction inclined to the axis. Axial flow pump its liquid outflow direction parallel to the axis. The main categories of chemical pumps magnetic pump centrifugal pump sewage pump self-priming pump oil pump diaphragm pump screw pump gear pump shield pump submersible pump gear pump pipe pump corrosion-resistant pump acid pump multi-stage pump stainless steel pump liquid pump and so on. Submerged pump and medium in contact with the parts, Department of polyvinyl butyral modified phenolic glass fiber, high temperature molded phenolic fiberglass parts, coupling pipe, the liquid pipe using a semi-dry roll made of technology Phenolic fiberglass pipe, impeller sleeve assembly are used phenolic cement and submerged pump shaft stick together, the assembly of the submarine are bonded with phenolic cement, into the liquid all without metal and media contact, corrosion resistance is absolutely reliable , The product has the advantages of light weight, high strength, no distortion, temperature resistance, corrosion resistance and the like, and can partially replace the precious metals such as aluminum-containing stainless steel, iron and titanium alloy in corrosion protection. Anti-corrosion liquid under the pump features: 1, running stable performance, and energy efficient. 2, high efficiency, stable work, small vibration, low noise, long life, less maintenance, low maintenance costs. Through the above introduction, we can already very clearly understand that the corrosion-resistant liquid pump with high efficiency and energy saving, long service life, less maintenance costs and other advantages, its advantages make it in the chemical, acid, alkali, smelting Acid, alkali, organic solvent, strong oxidant, etc. for transporting rare earth, pesticide, dye, medicine, paper making, electroplating, pickling, petrochemical, smelting, dye, pharmacy, Widely used in other fields.
