Causes of sealing problems of acid-resistant self-priming pump

Causes of sealing problems of acid and alkali resistant self-priming pump:
The main results are as follows:

1. During the operation, the axial force increases due to abnormal conditions such as holding pressure, cavitation and emptying, and the contact surface between the dynamic and static rings is separated.
2. When the mechanical seal is installed, the amount of compression caused is large, which leads to the damage of the friction pair.
3. The seal between the moving rings is so tight that the spring can not play its adjusting role, resulting in axial floatation.
4. The static ring seal ring is loose, the moving ring floats, and the static ring will break away from the static ring seat because of the huge dynamic action.
5. Poor working environment may cause pollution particles to enter the friction pair and cause damage to the dynamic and static rings.
6. The type selection of the design is not accurately estimated in the design, which may lead to operation errors in the work, or the dynamic and static rings may not be debugged accurately.

During the operation of the acid-alkali resistant self-priming pump, there may be sudden leakage, which is caused by wear and tear caused by long-term use, as well as improper operation or maintenance during use.

1. If pressure holding, cavitation or emptying occurs for a long time in the mechanical seal, the sealing property of the mechanical seal will be damaged.
2. The actual output does not meet the normal standard, which leads to the accumulation of some gases in the mechanical seal. Under the influence of this condition, the medium is gasified, resulting in seal failure.
3. The return flow exceeds the scope of the mechanical seal, which causes the sediment in the container to float and damage the tightness of the mechanical seal.
4. the mechanical seal has been stagnant for a long time, which leads to the problems of friction pair and manual turning in the mechanical seal, and further damages the mechanical seal.
5. Some substances that will corrode the mechanical seal appear in the medium, which is not conducive to the good sealing of the mechanical seal.
6. the working condition is not fixed, and it changes or adjusts frequently.
7. The temperature of the working environment will also affect the tightness of the mechanical seal under certain conditions.
8. The sudden occurrence of mechanical seal failure or power outage will have a great impact on the performance of mechanical seal.
