Scientific application method of self-priming magnetic pump: preparation before starting: 1 Test whether the rotation direction of the motor is correct (the direction indicated on the self-priming magnetic pump body), and the test time shall be short to avoid dry wear of the internal accessories of the self-priming magnetic pump. 2 Open the exhaust valve to fill the whole self-priming magnetic pump body with liquid, and close the exhaust valve when it is full. 3. Check whether all parts are normal. 4. The high-temperature type shall be preheated first, and the heating rate shall be 50. C / h to ensure uniform heating of all parts.

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?

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

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.

The function of the stainless steel centrifugal pump impeller is to transfer the mechanical energy of the prime mover directly to the liquid to increase the static pressure energy and kinetic energy of the liquid (mainly increasing the static pressure energy).
How Does the Stainless Steel Centrifugal Pump Work?

How Does the Stainless Steel Centrifugal Pump Work?

The stainless steel centrifugal pump impeller is installed in the pump shell and fastened on the pump shaft, which is directly driven by the motor. A liquid suction pipe is connected with the suction pipe in the center of the pump housing. The liquid enters the pump through the bottom valve and suction pipe. The liquid discharge port on the pump shell is connected with the discharge pipe.

Acid and alkali-resistant vertical pumps can safely transport strong acids, strong alkalis, highly toxic, organic solvents, and pure and precious chemical media, fully meeting strict safety, reliability, and ecological and environmental protection requirements. Low solid barrier rate, suitable for various chemical processes; no need to fill water after one-time installation, installation of the bottom valve, and convenient maintenance are the most ideal pumps to replace bulky submerged pumps.
