Advantages and features of sewage pump seals

As we all know, the seals inside the sewage pump parts are a crucial link. If the seals are of poor quality, the sewage pump is prone to water leakage and 

other faults, so it is very important to choose a good seal. The sewage pumps produced by our Dingfei Pump Industry all use high-quality seals. We choose 

mechanical seals rather than soft packing seals. In contrast, the characteristics and advantages of mechanical seals are mainly as follows:

1. The service life can generally be used in oil pumps and clean water pumps for 1 to 2 years or more, and in chemical pumps, it can usually reach more than half a year;

2. Friction power consumption. The friction power of mechanical seals is only 10% to 50% of the soft packing seal;

3. The shaft or sleeve is basically free from friction;

4. The repair cycle can be automatically compensated after the end face wear for a long period of maintenance. Generally, there is no need for frequent repairs;

5. Good vibration resistance is insensitive to vibration, swaying of the rotation axis and the deflection of the shaft to the sealing cavity;

6. The seal is reliable during long-term operation. The sealing state is very stable and the leakage amount is very small. According to rough statistics, the leakage 

amount is generally only 1/100 of the soft packing seal;

7. Wide application scope. Mechanical seal can be used for sealing of low temperature, high temperature, vacuum, high pressure, different speeds, as well as various 

corrosive media and abrasive-containing media.

8. The "zero leakage" needs in many factories today cannot meet this requirement; the warehouse adapts to a wide range of areas and is more arbitrary, but for factories, 

frequent replacement or maintenance will cause great losses to the factory.

Of course, things are divided into two parts. There are advantages and disadvantages. The main disadvantages are as follows:

①The structure is relatively complex and has high requirements for manufacturing and processing;

② Installation and replacement are more troublesome, and workers are required to have a certain level of installation technology;

③ When an accident occurs, it is difficult to deal with;

④ High one-time investment.

Overall, the advantages are far greater than the disadvantages, and the so-called disadvantages are actually not disadvantages, but the cost will be higher. It tests

 the conscience and long-term planning of the enterprise. The quality of the sewage pump requires the use and supervision of the majority of users. Our Dingfei
