Features and uses

In order to meet the development needs of electric power, metallurgy, coal and other industries, aiming at the characteristics of ash removal and slurry conveying conditions, on the basis of decades of experience in slurry pump design and manufacturing, extensively absorbing domestic and foreign advanced technologies and research results, developed a my country's new generation of ZGB(P) series slurry pumps with large flow rate, high lift and multi-stage series connection.

The main technical features of this series of products are as follows:

• Using modern CAD design method, excellent hydraulic performance, high efficiency and low wear rate;
• Wide flow channel, good anti-clogging performance, superior cavitation performance;
• Adopt impeller plus packing combination seal and mechanical seal to ensure no leakage of slurry;
• Reliability design ensures that the mean time between failures (MTBF) of the whole machine is greatly improved;
• The metric bearings are lubricated with thin oil, and the lubrication and cooling system is reasonably set to ensure that the bearings operate at low temperature;
• The flow-passing parts are made of special materials, which have good wear resistance and corrosion resistance;
• After special treatment, it is used in seawater ash removal and seawater and salt spray electrochemical corrosion conditions;
• Multiple stages can be used in series within the allowable pressure range. Its allowable Max working pressure is 3.6MPa.

This series of slurry pump products have the advantages of reasonable structure, high efficiency, reliable operation and convenient maintenance. It is widely used in electric power, metallurgy, mining coal, building materials, chemical industry and other industrial sectors to transport abrasive or corrosive slurry, especially power plant ash.

ZGB(P) series slurry pumps are horizontal, single-stage, single-suction, cantilever, double-casing, centrifugal slurry pumps.

The flow parts of the ZGB and ZGBP slurry pumps of the same caliber can be interchanged, and the external and installation dimensions are exactly the same. The transmission part of the ZGB(P) series slurry pump adopts a horizontal split type thin oil lubricated bracket, and is equipped with two sets of internal and external water cooling systems.

Add cooling water if necessary. Refer to Table 1 for the reserved cooling water connection and cooling water pressure.

There are two types of shaft seals for ZGB(P) series slurry pumps: combined impeller and packing seal and mechanical seal.

It is recommended to use a mechanical seal with high-pressure shaft seal water for all series-connected slurry pumps (secondary or above). Single-stage or series-stage adopts combined impeller and packing seal.
