ZJE filter press feed pump

The radial seal of the ZJE filter press feed pump reduces the shaft deviation compared to a single pump, thus reducing the need for packing seals and mechanical seals. Generally, shorter shafts are selected to allow for smaller deviations, which can improve the material used to dilute the high-pressure water inside the packing box seal cavity and extend the service life of the slurry pump. If dilution cannot be used for sealing, it is generally used for single-stage pumps, but the efficiency is reduced by 3%.

Construction machinery (shafts, bearings, shaft seals, pumps, etc.)

Shafts and bearings have high strength, stiffness, and spiral impellers can generally withstand heavy loads. In heavy load situations, sliding bearings and ball bearings are used, which are suitable for light loads. The radial seal of the ZJE filter press feed pump reduces shaft deviation compared to a single pump, which can reduce the need for packing and mechanical seals. Generally, shorter shafts are selected to allow for smaller deviations, which can improve the material used to dilute the high-pressure water inside the packing box seal cavity and extend its service life. If dilution cannot be used for sealing, it is generally used for single-stage pumps, but the efficiency is reduced by 3%.

Mechanical seals adopt a partially balanced structure and can be used for transporting liquid cooling. In some cases, when idle, dual mechanical light loads must be used. For general mechanical seals, a special mechanical seal structure must be used under heavy load conditions.

The ZJE filter press feed pump is a topic of concern for the user unit. There are many factors that determine the price. For example, factors such as the material used for the pump body, specifications, manufacturer, and environment.

Material used for pump body

Common materials include cast iron, high chromium alloys, stainless steel, etc. The difference in material is the main factor directly affecting the price.

Cast iron parts have a low price, but their usage is relatively limited. Any solid or corrosive material cannot be used. So now there is almost no production.

Stainless steel material, which can be divided into many types such as 304, 306, 321, etc. Due to the variety of stainless steel types, the price of the ZJE filter press feed pump is also determined based on the material. Due to various working conditions and conveying media, duplex stainless steel is currently the most commonly used material, which is expensive and generally more than twice that of high chromium alloys. Therefore, there are not many pumps made of this material, but they can be customized according to different user working conditions.

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 in a stopped state, 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 machine seal requires cooling water for sealing and cooling, and the gearbox 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.
