Puhou Pump Industry Spot ZJL Submerged Slurry Pump Direct Supply

The ZJL type is a single-stage, single suction, vertical centrifugal slurry pump. This series of pumps adopts the solid-liquid two-phase flow theory and is designed according to the principle of minimizing losses. The geometric shape of its flow components conforms to the flow state of the medium, reducing local and hydraulic losses such as eddies and impacts, thereby reducing wear on the flow components, improving hydraulic efficiency, and reducing operating noise and vibration; The overcurrent components of this series of pumps are made of high hardness alloy cast iron, which has high wear resistance, corrosion resistance, and impact resistance, thereby improving their service life.

Product Overview:

ZJLThe submersible slurry pump is a vertical centrifugal slurry pump that is immersed underwater and used to transport abrasive, coarse particle, and high concentration slurry. It does not require any shaft seal or shaft seal water and can work normally even under conditions of insufficient suction.

ZJLThe overcurrent components of the pump are made of wear-resistant metal.

ZJLThe components of the submersible pump are equipped with rubber liners, which are suitable for conveying abrasive slurry without edges and corners.

According to the level of the slurry pool liquid, different lengths of pump drive shafts or suction pipes can be selected.

By adopting multiple speeds and variations, the pump operates under working conditions with a long service life and high operational efficiency, and can meet various harsh conveying conditions.

Overall performance of ZJL submersible slurry pump: This series of slurry pumps is mainly used to treat corrosive slurries containing solid particles. The maximum weight concentration of the slurry processed by this series of pumps is 50% for mortar and 60% for slurry.
Industrial pumps are widely used in chemical, petroleum, metallurgy, light industry, synthetic fiber, environmental protection, food, medicine and other sectors. They play a significant role in improving product quality, reducing leakage, preventing pollution, and improving the environment. The special requirements for pumps in chemical production are roughly as follows:
1. Can adapt to the needs of chemical processes
In the chemical production process, pumps not only play a role in conveying materials, but also provide the necessary amount of materials to the system to achieve material balance in chemical reactions and meet the pressure required for chemical reactions. Under the same production scale, it is required that the flow rate and head of the pump be relatively stable. Once the production fluctuates due to certain factors, the flow rate and outlet pressure of the pump can also change accordingly, and it has high efficiency.
2. Corrosion resistance
The media transported by chemical pumps, including raw materials and intermediate products, are mostly corrosive. If the material selection of the pump is improper, the components will corrode and fail during pump operation, making it impossible to continue working.
For certain liquid media, non-metallic materials such as ceramic pumps, plastic pumps, rubber lined pumps, etc. can be used if suitable corrosion-resistant metal materials are not available. Plastic has better chemical corrosion resistance than metal materials.
When selecting materials, one must consider not only their corrosion resistance, but also their mechanical properties, machinability, and price.

operation control
(1) The pH value of the absorption tower slurry is the core of the wet desulfurization system reaction process. Increasing the pH value of the slurry and adjusting the desulfurization operating parameters in a timely manner due to excessive slurry density can easily cause scaling on the pipe wall or hinder the inlet filter screen. Therefore, it is necessary to analyze the parameter status through data analysis to maintain it in an optimal state.
(2) Operators should improve their operational skills and equipment inspection quality. When the slurry circulation pump is stopped, pipeline flushing should be strengthened to prevent residual slurry in the pipeline. During equipment inspection, carefully observe the oil level, oil quality, cooling water return flow rate, and equipment appearance. Use thermometers and vibration meters to measure the temperature and vibration of the equipment. If any abnormalities are found in the equipment, decisive measures should be taken, such as adding lubricating oil to the bearing box or switching to the standby pump for operation. During the pump shutdown period, maintenance personnel should promptly repair the equipment, and warehouse personnel should prepare spare parts for the equipment to ensure timely replacement and normal operation.
(3) The process water system is an important guarantee for the operation of equipment. The slurry circulation pump requires cooling water for sealing and cooling, and the reducer also needs cooling water for cooling. Therefore, it is necessary to ensure the normal operation of the process water system. The inlet filter screen of the process water pump can filter impurities, so that the pipeline can be unobstructed, and the service life of the mechanical seal dynamic and static rings can also be extended. The outlet of the process water pump maintains normal pressure in order to have sufficient water to cool down the equipment, and the sealing water in the machine seal can also better block the leakage of the slurry.
