Flotation horizontal foam pump is widely used in mining, chemical industry and many other fields. The following is a detailed introduction to its use:

Application scenarios

Mining flotation operation: It is used to transport pulp containing a large amount of foam in the flotation process of non-ferrous metals (such as copper, lead, zinc, etc.), ferrous metals (such as iron), and non-metallic ores (such as fluorite, phosphate ore, etc.). For example, in the copper mine flotation plant, the slurry rich in copper mineral foam produced by mixing, dosing and other processes needs to be transported to the next link by the flotation horizontal foam pump for foam scraping and subsequent concentrate treatment and other operations.

Chemical industry: some chemical products production process involves the transfer of foam materials after gas-liquid separation, and this pump will also be used. For example, in the production of some detergent raw materials, the materials with foam generated after reaction can be transported through it to facilitate the subsequent processing, packaging and other steps.

working principle

It relies on the rotation of the impeller to form a low-pressure area in the pump cavity, so that the fluid containing foam is sucked into the pump body. The impeller works on the fluid to increase its energy, and then transmits foam slurry along the pipeline. At the same time, its special structural design can better adapt to foam, a medium with relatively special gas-liquid mixing and liquidity, reduce the occurrence of foam rupture, cavitation and other undesirable phenomena, and ensure stable delivery flow and pressure.

Performance characteristics

Good cavitation resistance: because foam contains a large amount of gas, ordinary pumps are prone to cavitation and damage pump body parts due to gas accumulation during transmission. However, flotation horizontal foam pumps often adopt designs such as special impeller shape, increased inlet size, etc. in structure, which can effectively reduce the probability of cavitation and extend the service life of the pump.

Stable flow transmission: even though the gas-liquid ratio of the conveyed media such as foam pulp will fluctuate to some extent, it can still maintain a relatively stable flow output through reasonable speed regulation and internal flow channel optimization, so as to ensure that the whole production process will not be subject to flow cutoff and other conditions affecting the subsequent processes.

Adapt to certain corrosive media: In flotation processes, slurry usually has a certain acidity or alkalinity, and materials in the chemical industry may also be corrosive. Many pumps of this type use corrosion-resistant materials (such as stainless steel impellers, pump casings, and other components), which can resist medium corrosion to a certain extent and ensure reliable operation.

Precautions for use

Pre start inspection: Ensure that all components of the pump body are securely installed and that the impeller rotates smoothly without any jamming; Check if the sealing device is intact to prevent leakage; At the same time, check whether the inlet and outlet pipeline connections are correct and whether there are any blockages, and pre inject an appropriate amount of medium to be transported into the pump chamber and inlet pipeline to facilitate smooth start-up.

Monitoring during operation: It is necessary to pay attention to the operating current, voltage and other parameters of the pump to ensure that it is within the normal working range; Pay attention to changes in import and export pressure. If there are abnormal fluctuations in pressure, it may indicate pipeline blockage or internal pump failure; Also pay attention to listening for any abnormal sounds during pump operation, such as friction sounds, impact sounds, etc. Once discovered, stop the machine for inspection in a timely manner.

Regular maintenance: Disassemble the pump body regularly according to the prescribed operating hours or workload, inspect, clean, and replace key components such as impellers, shaft seals, and bearings with severely worn parts; Perform maintenance work such as lubrication and fastening of power components such as motors to ensure that the pump can be in good working condition for a long time.

Common faults and solutions

Insufficient flow: One possible reason is the blockage of the inlet pipeline, which requires cleaning of pipeline debris; The second issue is impeller wear, which requires the replacement of a new impeller; Thirdly, the speed is insufficient. It is necessary to check the motor and transmission device and adjust them to the appropriate speed.

Large pump body vibration: It may be due to impeller imbalance, and it is necessary to perform dynamic balance correction on the impeller again; or if the pump shaft is bent, it needs to be straightened or replaced; It is also possible that the anchor bolts are loose, just tighten the anchor bolts.

Sealing leakage: If it is a mechanical seal leakage, it may be due to wear on the sealing surface, and the sealing component can be replaced; If the packing seal leaks, the packing gland can be tightened appropriately, but care should be taken not to tighten it too tightly to avoid affecting the normal rotation of the pump shaft.

In a word, the flotation horizontal foam pump plays a key role in the production process of related industries. Proper use and maintenance can ensure its efficient and stable operation and provide strong support for the smooth development of production activities.
