In order to meet the development needs of industries such as power, metallurgy, and coal, and based on the characteristics of ash and slag removal and slurry transportation conditions, our factory has developed the latest generation of ZGB (P) series slurry pumps in China with high flow rate, high head, and multi-stage series connection, based on decades of experience in slurry pump design and manufacturing, and extensive absorption of advanced technologies and research achievements at home and abroad. The main technical features of this series of products are as follows:

Adopting modern CAD design methods, it has excellent hydraulic performance, high efficiency, and low wear rate;

Wide and smooth flow channels, good anti clogging performance, and superior cavitation performance;

Adopting a combination of impeller and packing seal and mechanical seal to ensure no leakage of slurry;

Reliability design ensures a significant increase in the mean time between failures (MTBF) of the entire machine;

Adopting thin oil lubrication for metric bearings, setting up lubrication and cooling systems reasonably to ensure that the bearings operate at low temperatures;

The overcurrent components are made of special materials with good wear and corrosion resistance; Specially processed for seawater ash removal and electrochemical corrosion of seawater and salt spray conditions;

Within the allowable pressure range, it can be used in series in multiple stages, with a maximum allowable working pressure of 3.6 Mpa.

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

summary:

The ZJB slurry pump is an efficient, energy-saving, single-stage, single suction centrifugal slurry pump developed by Shandong Yanshan Pump Industry Co., Ltd. According to the structural form, it can be divided into two types: horizontal (ZJB type) and vertical (ZJLB type). Horizontal pumps are divided into 500 according to the outlet diameter mm、450mm、400mm、350mm、300mm、250mm、200mm、150mm、100mm、80mm、65mm、50mm、40mm Waiting for multiple specifications.

This series of slurry pumps has innovations in hydraulic and structural design. The overcurrent components are made of self-developed high chromium wear-resistant alloy cast iron with strong abrasion resistance, which has significant characteristics such as high efficiency, long service life, light weight, reasonable structure, reliable operation, low vibration, low noise, and easy maintenance. Suitable for industries such as power, mining, metallurgy, coal, building materials, chemical, food, water conservancy, and sewage treatment, it is used to transport abrasive or corrosive slurries containing solid particles. The maximum weight concentration of the solid-liquid mixture is 45% for mortar and 60% for slurry. It can be operated in series according to user needs. The performance indicators of this series of slurry pumps are at the leading level in China, and the efficiency indicators of most pumps have reached the international level.

The ZJC series slurry pump adopts our company's unique special structure. This series of products is designed as a single-stage slurry pump according to the special needs of the filter press in China's coal selection process. When the filter press is working, the flow rate of the pump decreases and the pressure increases. Due to process requirements, sealing water is not allowed to be injected into the shaft seal of the pump, resulting in slurry leakage at the packing (even with a secondary impeller power seal, it is useless), polluting the working environment, damaging the packing seal, increasing on-site maintenance workload, and reducing the overhaul life of the pump. The characteristic of this series of pumps is to ensure that there is no slurry leakage at the packing without sealed clean water. This series of pumps can also be used in working environments where the backflow pressure at the inlet of the slurry pump does not exceed 10m and there is no sealed clean water. Its performance parameters and installation dimensions are exactly the same as those of ZJB slurry pumps of the same model.

The ZJB series slurry pump has been listed as a promotion project for power technology achievements by the Ministry of Energy, promoted and selected as a product by the Ministry of Metallurgy and the Ministry of Coal Industry, and listed as the main auxiliary equipment selection product for 50-300MW thermal power units by the Ministry of Electric Power, the Electric Power Planning and Design Institute, and the Equipment Package Bureau.

Structural characteristics of ZJB series slurry pump:

● Pump sports lottery with double-layer metal structure inside and outside

The pump casing is vertically split.

The outlet position can be rotated at 45 ° intervals and installed in eight different positions for joint use.

Bearing lubrication: Divided according to different bearing housings:

The box type adopts thin oil lubrication.

Cylindrical lubrication with grease

● Bearing box △ embedded cover adopts thin oil or grease lubrication

Shaft seal type:

● Auxiliary impeller shaft seal: suitable for single-stage pumps and first stage pumps used in series combination. The lubrication of the packing used for the shutdown seal is done with normal pressure water or grease.

Packing shaft seal: Suitable for second stage pumps and above used in series, requiring shaft seal water.

Impeller form

Closed impeller: The impeller is in a closed form, with good wear resistance and high pump efficiency.

Open type impeller: The impeller has a large flow capacity and needs to be cleaned regularly when conveying dirty materials, making the cleaning work relatively easier.

Structural characteristics of ZJLB slurry pump:

Single layer shell, metal structure.

● Direct or belt drive.

Rolling bearing grease lubrication
