2. When the outlet valve of high-power PP chemical pump is closed, the fluid in the pump will get hotter and hotter, and the bearing will be burnt out in severe cases. After setting the small flow pipeline, it can ensure that a certain flow of liquid always flows through the pump during the operation of the pump to prevent this phenomenon.
3. When working at a small flow rate, the pump shaft will be subjected to additional radial force. Setting a small flow pipeline can always make a certain amount of fluid flow through the pump when the pump is running, and prevent the pump shaft from being subjected to excessive radial force;
4. Sometimes the orifice plate is used in the small flow pipeline of the pump, so that even if the pump outlet valve is closed by misoperation, the stable operation of the PP chemical pump can be ensured without damage. The advantage of using orifice plate is that manual adjustment is not required. If only the stop valve is used for adjustment, it is difficult to control the flow rate near the small flow rate of the pump, whether it is large flow rate or small flow rate.
