Reasons for water leakage, pump body deformation or cracking of Dalian acid resistant pump

Dalian acid resistant pumps can be widely used in electroplating, LED, metallurgy, PCB, and chemical liquids containing abrasive solid particles transported by environmental protection industries. For example, in the chemical industry, impurities can also transport corrosive liquids containing crystals when transporting slurry, electroplating wastewater, and PCBs in metallurgical beneficiation plants. About 80% of the vertical acid and alkali resistant pumps used in the industrial sector.

The acid alkali pump has good acid and alkali resistance and is suitable for use in processing plants with high chemical content in the chemical industry; PVDF corrosion-resistant material has good corrosion resistance. Based on the above situation, the selection of lining components for vertical acid alkali pumps needs to be reasonably selected according to the type of chemical industry to improve the utilization rate of vertical acid alkali pumps.

Reasons for water leakage, pump body deformation or cracking of Dalian acid resistant pump

1. The temperature of the liquid itself exceeds the rated operating conditions

2. The acid and alkali resistant pump is in a long-term high-pressure state

During installation, the screws were locked too tightly, causing overheating and resulting in expansion and rupture

4. The material of the pump body of the self-priming pump is not suitable for use in this medium

5. The device has been used for too long, resulting in aging and other issues

The working pressure of acid resistant vacuum pumps should meet the vacuum and working pressure requirements of vacuum equipment. For example, a working vacuum degree of 10 nanograms is required in the vacuum drying process, and the vacuum degree of the selected vacuum pump should be at least 2 nanograms, preferably up to 1 nanogram. Usually, the vacuum degree of the pump is selected to be half to an order of magnitude higher than the working vacuum degree of the vacuum equipment.

The acid resistant pump mechanical seal is sealed by two sealing surfaces that are perpendicular to the shaft and rotate relative to each other. The dynamic ring is pressed onto the impeller shaft, and the static ring is installed on the sealing seat of the cover chamber. The two ends are always close to each other through elastic elements, thus achieving the purpose of sealing. The mechanical seal of the acid resistant pump adopts a static ring holder to adjust the static and dynamic ring seals. The radial seal is completed by an O-ring, which has strong elasticity, good sealing performance, and reliable isolation sealing.
