A、 Problem with plunger working conditions

The plunger head of a piston pump must withstand significant pressure and impact loads during operation. If the working conditions are too harsh, it can also cause the plunger head to break. For example, long-term overloading or overloading of the plunger pump, as well as the corrosive or viscous working medium of the plunger pump, can exacerbate the wear and tear of the plunger head, ultimately leading to its fracture.

B、 Material issue of plunger

The main materials for the plunger head of a piston pump are steel, cast iron, etc. If the material quality is poor or there are problems such as looseness and inclusions, it can cause the plunger head to break during operation. In addition, if the hardness of the plunger material is insufficient, it can also cause the plunger head to break.

 

 

C、 Methods to prevent plunger head breakage

1. Choose high-quality plunger materials. The material quality of the plunger head directly affects the working life of the plunger. Choosing a high-quality plunger material can minimize the problem of plunger head fracture.

 

2. Reasonably arrange the working conditions of the piston pump. When choosing a piston pump, it is necessary to select the appropriate plunger pump model according to the actual situation and arrange the working conditions of the piston pump reasonably. This can reduce the wear and tear of the plunger head and extend the service life of the piston pump.

 

3. Regularly maintain and repair the plunger pump. Regularly check the working status of the piston pump. If cracks or deformations are found in the plunger head, it needs to be replaced or repaired in a timely manner.

 

4. Pay attention to the transportation process of the plunger pump. During the transportation of the plunger pump, it is necessary to pay attention to the transportation status and mode of the plunger pump to avoid severe vibration and collision, which may cause damage to the plunger head.

 

In summary, the fracture of the plunger head of a plunger pump is usually caused by factors such as the plunger material and working conditions. To avoid the fracture of the plunger head, corresponding protective measures need to be taken, such as selecting high-quality plunger materials, arranging the working conditions of the plunger pump reasonably, and regularly maintaining the piston pump.
