GC-type boiler feed pump horizontal single suction multistage centrifugal pump, mainly for boiler feed water, so aka boiler feed pump. This series of boiler feed water pump is suitable for conveying water with temperature lower than 110 ° C or other non-corrosive liquids with physicochemical properties similar to water. It is widely used in boiler feed water and urban water supply of industrial and mining enterprises.
Inorganic acids, also known as mineral
acids, are a general term for acids in inorganic compounds. Inorganic acids, in
general, are inorganic compounds that can dissociate hydrogen ions. A compound
consisting of hydrogen and a non-metallic element or a group thereof. For
example, hydrochloric acid (HCl), nitric acid (HNO3), boric acid (H3BO3),
sulfuric acid (H2SO4), carbonic acid (H2CO3), phosphoric acid (H3PO4) and the
like.
According to the composition, inorganic
acids can be divided into oxygen-containing acids, anaerobic acids, complex
acids, mixed acids, superacids, etc., according to the degree of dissociation,
can be divided into strong acids and weak acids, but also according to the
number of hydrogen ions in the molecule can be ionized into monobasic acids,
dibasic acids and polyacids.
Inorganic acids are mostly used to provide
hydrogen ions.
Inorganic acids are divided into inorganic hydrogenic acids and inorganic oxygenated acids according to their composition.

Features GC-type pump for the multi-stage sub-type, 1-1 / 2GC-4GC import and export of the four models in the water inlet and outlet, respectively, are up vertically, its head can be used according to the need to change the pump series The assembly of the pump is good or not, have a great impact on the performance, especially the relative position of the outlet of each impeller and the inlet of the guide vanes, the center of outlet of each impeller must be aligned with the center of the guide vane, Reduced flow, reduced head, poor efficiency, to help pay attention after assembly in the repair, if any deviation must be adjusted.
GC-type main components of marine pumps shaft, sleeve, inlet, impeller, guide wing, seal ring, the middle section, the water section, balance ring, balance plate, the tail cover.
Into the water section, the middle section, the water section and tail cover are made of cast iron, together to form a pump studio.
The impeller is made of cast iron, there are blades inside, the liquid enters along one side of the axial direction. Because the impeller is under pressure before and after, there must be axial force, which is borne by the balance plate.
The shaft is made of high-quality carbon steel with an impeller in the middle, fastened to the shaft with keys, bushing and bushing nuts. One end of the shaft is equipped with coupling parts and is directly connected with the motor. When viewed from the direction of rotation, the pump shaft rotates clockwise.
The sealing ring is made of cast iron to prevent the high-pressure water in the water pump from leaking back into the water part, respectively fixed in the water inlet section and middle section, which is a wearing part and can be replaced after being worn.
Balance ring is made of cast iron, fixed in the water section, which together with the balance plate balance device.
Balanced disc made of wear-resistant cast iron, mounted on the shaft, located between the outlet section and the tail cap, the balance of axial force.
Sleeve made of cast iron, located in the two packing room for the fixed impeller and pump shaft protection purposes. For wearing parts, worn spare parts can be replaced.
Bearing is a single row radial ball bearings, calcium-based butter lubrication.
Packing seal from the inlet section and tailgate on the filling room, packing gland, packing ring and packing and other components, a small amount of high-pressure water into the packing room from the role of water seal. The degree of tightness of the packing must be appropriate, not too tight, nor too loose, the liquid can be one by one to ooze to prevail. If the packing is too tight, the sleeve can easily generate heat while consuming power. Filler is too loose, due to liquid loss to reduce pump efficiency.
Use GC series pump is especially suitable for boiler feed water, but also can be widely used in pressure vessel water supply, hot water circulation, high-rise building water supply, farmland irrigation, fire pressurization, hydraulic flushing, food, brewing, medicine, chemical, aquaculture, environment Protection, chemical process and machine tools and other industries, as the water supply and drainage of power equipment.
The general formula of hydroic acid is MHm, the structure is relatively simple, it is some hydride of the periodic table, the group of elements. They are in an aqueous solution, can give protons, appear acidic.
For hydrogenic acid, the higher the electronegativity of its central atom M, the stronger the ability to attract electrons, the easier it is to give protons, and the stronger its acidity. For the same cycle, as the family of M changes, the electronegativity of M gradually increases in the sequence, and the acidity of its corresponding MHm is gradually enhanced.
Contains grade acids
The general formula for oxygenated acids is XOm(OH)n, where X is the central atom.
The structure of the oxygenated acid is more complex than that of the hydroacid, and its structure is related to the number of cycles in which the central atom X is located. In the second cycle, H3BO3,H2CO3, HNO3, and BO32-, CO32-,NO3- are planar structures that contain out-of-bound π bonds.
