Overview:
GMZ type desulfurization pump is a reference to our company thermal power plant flue gas desulfurization engineering specifications for the current thermal power plant desulfurization system using pump delivery medium characteristics, absorbing the technical advantages of similar products at home and abroad, the introduction of the world's most advanced resistant to corrosion, abrasion France Cr30A which contains Mo, Cr, Cu, N and added a certain active element, good abrasion and corrosion resistance and erosion resistance, and good strength and toughness, is a new generation of energy efficient products, can replace imported products. Taishan Power Plant in China have been well received. GMZ desulphurization pump can also be used for FGD system of thermal power plant limestone, lime, gypsum slurry circulation transport, also used in metallurgy, mining, electricity, coal, water, chemicals, light industry, petroleum and other departments containing a large number of solid materials abrasive Or corrosive slurry.

Structure Description:
GMZ series pump, in addition to the pump head part (including before and after the pump shell, volute, front and rear fenders, impeller, etc.) of different structures, the rest of the structure similar to the same series of transmission parts, according to the following pump head part, And transmission part, respectively, described the structural characteristics.
1, pump head part: GMZ series pump is a double pump shell structure, that is, before the pump casing, after the pump casing and with replaceable over-current part (including the impeller, volute, the front guard, rear guard). Front and rear pump housing according to the working pressure, made of gray cast iron or ductile iron, vertical in the open, bolted, after the pump casing and the bracket with a bolted connection, the pump outlet can be rotated at eight angles installation, impeller front and rear Cover with a back blade to reduce leakage, improve pump life and efficiency. All types of pump imports are horizontal, from the direction of transmission to see the pump for clockwise rotation.
2, shaft seal part: There are three forms of shaft seal, deputy impeller shaft seal and packing shaft seal, mechanical seal.
(1) Vice impeller shaft seal: When the positive pressure of the pump inlet is not more than 10% of the pump outlet pressure, the single-stage pump or the multistage third-stage pump can adopt the auxiliary impeller shaft seal, Dilution of pulp, sealing effect is good.
(2) packing shaft seal: packing shaft seal structure is simple, easy maintenance, the need to use shaft sealing water, not suitable for use in the case of impeller shaft seal and pump suction conditions can be used packing shaft seal.
(3) mechanical seal: For not suitable for the above two kinds of shaft seal conditions, the use of mechanical seal to reduce the number of shaft seal part of the maintenance.
3, the transmission part: This series of pumps are used in the same series of transmission, including brackets and bearing components, the pump shaft diameter, good rigidity, short cantilever, in harsh conditions will not bend and vibration, the use of single row tapered roller bearings Sub-bearings and deep groove ball bearings, combined use to withstand the maximum axial and radial pump load, bearing thin oil lubrication, seal body ends at both ends of the cover, which can effectively prevent pulp and other dirt into the bearing, the pump at The bearing body is equipped with two hose connectors, which can be connected with the water source to cool the bearing chamber. Therefore, the bearing body can work under higher ambient temperature to ensure the safe operation of the bearing and have a higher life expectancy.
