Acid and alkali resistant pump is a wide range of general-purpose mechanical equipment, it is widely used in petroleum, chemical industry, power metallurgy, mining, ship selection, light industry, agriculture, civil and national defense departments, occupying an important role in the national economy Status. According to statistics in 1979, the output of acid and alkali resistant pumps in my country reached 1.256 million units. The electric energy consumption of acid and alkali resistant pumps accounts for more than 21% of the national electric energy consumption. Therefore, greatly reducing the energy consumption of acid and alkali resistant pumps is of great significance for energy saving.
How to Analyze and Judge the Leakage Cause of Acid and Alkali Resistant Vertical Pump?

How to Analyze and Judge the Leakage Cause of Acid and Alkali Resistant Vertical Pump?

Dec 27, 2021

Acid and Alkali Resistant Vertical Pump leakage cause analysis and judgment 1. Acid and Alkali Resistant Vertical Pump leakage during installation static test. After the mechanical seal is installed and debugged, it is generally necessary to conduct static test and observe the leakage. If the leakage is small, most of them are moving ring or stationary ring, and the sealing ring has problems; 2. When the leakage is large, it indicates that there is a problem between the dynamic and static ring friction pairs. 3. On the basis of preliminary observation of the leakage and judgment of the leakage position, manually turn and observe. If there is no obvious change in the leakage, there is a problem with the static and dynamic ring seals; 4. If the leakage medium is sprayed along the axial direction, the moving ring sealing ring has most problems. If the leakage medium is sprayed around or leaked from the water cooling hole, the static ring sealing ring is mostly invalid. 5. In addition, leakage channels can also exist at the same time, but there are generally primary and secondary differences. As long as you observe carefully and are familiar with the structure, you can make a correct judgment.
Five Common Leakage Points of Acid and Alkali Resistant Vertical Pump

Five Common Leakage Points of Acid and Alkali Resistant Vertical Pump

Dec 25, 2021

12-252021

idling vertical acid and alkali resistant pump,There are many kinds and models of idling vertical acid and alkali resistant pumps, but the main leakage points are:
(l) Sealing between shaft sleeve and shaft;
(2) Sealing between moving ring and shaft sleeve;
(3) Sealing between dynamic and static rings;
(4) Seal between the stationary ring and the stationary ring seat;
(5) Seal the seal between the end cover and the pump body.
Generally speaking, the leakage between the extended shafts of the shaft sleeve and between the sealing end cover and the pump body is easy to find and solve, but it needs careful observation, especially when the working medium is liquefied gas or high-pressure, toxic and harmful gas. Other leaks are difficult to distinguish and judge. Only by observing, analyzing and judging the leakage symptoms on the basis of long-term management and maintenance practice can we draw a correct conclusion.
