Analysis on Application of Sewage Pump (1)

1. Sewage pump is a pump and motor connected, and at the same time into the liquid work under the pump products, and general horizontal or vertical sewage pump compared to the sewage pump has the following advantages: 1. Structure Compact, small footprint. The sewage pump can be directly installed in the sewage pond because of the submerged operation. It is not necessary to construct a special pumping station to install the pump and the machine, which can save a lot of land and infrastructure.

 

2. Installation and maintenance convenience. Small sewage pump can be installed free, large-scale sewage pumps are generally equipped with automatic coupling device can be automatically installed, installation and maintenance is very convenient.

 

3. Continuous operation for a long time. Sewage pump As the pump and motor coaxial, shaft short, light weight of the rotating parts, so bear the load on the bearing (radial) is relatively small, life expectancy much longer than the average pump.

 

4. There is no cavitation damage and irrigation water and other issues. In particular, the latter point to the operator to bring a great deal of convenience.

 

5. Vibration and noise, the motor temperature is low, no pollution to the environment.

 

It is because of the above advantages, sewage pump has been more and more attention, the use of more and more widely from the original simply used to transport water to the present can transport a variety of domestic sewage, industrial wastewater, construction sites Drainage, liquid feed and so on.

 

In the municipal engineering, industry, hospitals, construction, hotels, water conservancy construction and other industries play a very important role.

 

But anything is divided into two, the most critical problem for the sewage pump is the reliability of the problem, because the use of sewage pump is liquid in the case; transmission medium is a mixture of solid materials containing some of the liquid; pump and The motor is very close; the pump is a vertical arrangement, the weight of the rotating parts and the impeller to withstand water pressure in the same direction. These problems have made the sewage pump in the seal, the motor bearing capacity, bearing arrangements and selection requirements in general than the sewage pump is higher.

 

In order to improve the life of sewage pumps, and now most of the domestic and foreign manufacturers are in the pump protection system to find ways to leak in the pump, overload, over-temperature and other failures can automatically alarm, and automatically shut down for repair. However, we believe that in the sewage pump to set the protection system is necessary, it can effectively protect the safe operation of the pump.

 

But this is not the problem, the protection system is just a pump failure after a remedy, is a more passive approach. The key issue is to proceed from the root, completely solve the pump in the sealed, overload and other issues, this is a more proactive approach. To this end, we put the auxiliary impeller hydrodynamic seal technology and pump no-overload design technology applied to the sewage pump, the greater the pump seal reliability and carrying capacity, extended pump life.
