Fluorine centrifugal pump full product analysis

Fluorine centrifugal pump is a relatively special pump products, which are mainly used in corrosive medium transport in chemical production, electrolyte transport in non-ferrous metal smelting, pickling in automobile manufacturing, and Pharmaceuticals, petroleum, electroplating, dyes, pesticides, paper, food and other industries, so its production process is more stringent, Xiaobian here to introduce you the advantages of fluorinated centrifugal pump, characteristics, working principle, so that you can Learn more about it. Advantages inventory Fluorine centrifugal pump with rear door structure, one person can easily internal routine maintenance and replacement parts, without removing the pump import and export pipe, the actual use of the pump shows decay, wear, high mechanical strength, smooth operation, the structure Advanced and reasonable, reliable sealing performance, easy disassembly and maintenance, long service life and so on. Configuration of the metal bellows mechanical seal, on the grinding material: aluminum oxide VS PTFE, silicon carbide VS PTFE, carbide Carbide carbide, according to the conditions required to choose on the mill. Fluorine centrifugal pump full analysis of structural features Fluoride centrifugal pump main components using steel lining F46, high pump strength, the use of high-performance magnetic material "NdFeB" inside and outside the magnet, the isolation sleeve made of imported non-metallic materials, greatly Reducing the strong torque of the magnetic vortex to make the product more efficient and energy saving. The TIF lining fluorine centrifugal pump can continuously deliver high-concentration and strong-corrosive media with a density of more than 1.9t / m3. The driving mode is indirect induction without magnetic force. The driving magnet coupling is directly mounted on the motor shaft. The inner and outer magnets are completely isolated by the isolation sleeve assembly, so that the pump chamber is completely closed and the pump chamber is completely closed and indirectly driven by the magnetic coupling Impeller rotation on rotor assembly. Fluorine centrifugal pump isolation sleeve assembly with three-tier enhanced isolation. The contact liquid layer is made of one-time high-temperature molding of perfluorinated plastic F46 and has super corrosion resistance. The middle layer is a stainless steel sleeve reinforcement layer. This design enables the isolation sleeve to have higher mechanical strength and better pressure resistance. The outer layer is Reinforced sleeve, made of carbon fiber reinforced plastic, the material without magnetic loss, high pressure, if the outer magnet due to external forces or other reasons and enhanced sleeve contact, no sparks, to maintain a high level of safety performance. Working principle lined with fluorine centrifugal pump is mainly composed of liquid storage chamber, vortex chamber, backflow hole, impeller, pump cover composition, before starting the pump chamber should be filled with liquid, liquid storage chamber in the impeller high-speed gas-liquid mixture will be drawn into Vortex chamber pressurized into the gas-liquid separation chamber, this time, the proportion of air is less than the liquid, they naturally enter the pipe network, the liquid is automatically returned from the return hole and the reservoir chamber air again mixed by the impeller cycle pressurized into the gas-liquid separation chamber. ..... This process is repeated until the suction line air is exhausted; medium is transported to the conditions required for any place.

Ketone and Amine

Ketone is a compound in which a carbonyl group is attached to two hydrocarbon groups. According to the different hydrocarbon groups in the molecule, ketones can be classified into fatty ketones, alicyclic ketones, aromatic ketones, saturated ketones, and unsaturated ketones. According to the number of carbonyl groups, it can be further divided into mono-ketones, di-ketones and poly-ketones. In monoketones, if the two hydrocarbon groups attached to the carbonyl group are the same, it is called monoketone, such as acetone (dimethyl ketone). if different, it is called mixed ketones, such as acetophenone (phenyl methyl ketone). Ketone can not form hydrogen bonds, the boiling point is lower than the corresponding alcohol, but the carbonyl oxygen can form hydrogen bonds with water molecules, so the low carbon ketone (lower ketone) is soluble in water. Lower ketones are liquids with a pleasant odor and high carbon ketones (higher ketones) are solids.

Amine is an organic compound in which part or all of the hydrogen atoms in the NH3 molecule have been replaced by a hydrocarbon group. Most of the amines have alkalinity and can be combined with acid to form a salt, which is a raw material for producing synthetic dyes, drugs and so on.

According to the number of replaced hydrogen, it is divided into primary amine RNH2, secondary amine R2NH, tertiary amine R3N, quaternary ammonium salt R4N+X-, for example, methylamine CH3NH2, aniline C6H5NH2, ethylenediamine H2NCH2CH2NH2, diisopropylamine [(CH3)2CH]2NH, triethanolamine (HOCH2CH2)3N, tetrabutylammonium bromide (CH3CH2CH2CH2)4NBr.

Physical properties

Methylamine, dimethylamine, trimethylamine, and ethylamine are gases at room temperature, other lower amines are liquids; higher amines are solids;

The lower amines have ammonia smell, the trimethylamine has fishy smell, and the putrescine (propanediamine) cadaverine (butanediamine) has bad odor;

Aromatic amines are high boiling liquids or low melting solids;

Amine and water can form intermolecular hydrogen bonds;

Primary amines and secondary amines can also form hydrogen bonds between themselves.

Most aromatic amines are toxic. Aniline can cause aplastic anemia. It can be poisoned by inhalation, ingestion, or absorption through the skin. Ingestion of 0.25 mL can cause serious poisoning.

Beta-naphthylamine and benzidine are substances that can cause malignant tumors.
