The main problems in the production of most small and medium-sized paper mills are as follows:
1.As the boiler feed pump runs longer, the flow and lift are reduced.
2.The motor is unstable and will overheat.
3.After long-term operation, the pump body is overheated and the bearing is overheated.  
Industry Problems

The boiler is the core equipment of the paper mill. In the paper making process, steam is used in many aspects, such as preheating of raw materials, steam heating during cooking, and drying of the dryer section of the paper machine. 

The function of the boiler feed water pump is to supply the water in the deaerator storage tank with a certain temperature and to remove the oxygen, and then increase the pressure to the boiler to meet the needs of the boiler water. If the boiler feed pump fails, it will cause the paper mill to fail to guarantee the production, and even lead to shut down. 

The main problems in the production of most small and medium-sized paper mills are as follows:

2.The motor is unstable and will overheat.
3.After long-term operation, the pump body is overheated and the bearing is overheated.

How To Solve It?

It requires that when selecting a boiler feed pump, the company should pay attention to the following:
1.High stability and reliability of the pump
Self-balancing boiler feed pumps, self-balancing axial force loads minimize pump wear and system interference. The minimum axial residual force is absorbed by the thrust bearing, so that the pump shaft is always in the tension state, the force state of the shaft is uniform, and the stress peak is greatly reduced compared with the conventional one, which improves the rigidity and critical speed of the pump rotor.


2. High-efficiency of the pump
All over-current components are precision cast to ensure flow path size and flow path finish, which is 3-12% higher than the conventional multi-stage pump.
