How to avoid cavitation in RX High Temperature Low Cavitation Water Pump
RX High Temperature Low Cavitation Water Pump has relatively high requirements for pump body structure, pressure resistance, and stability. Good flow channel design and impeller design can minimize the damage caused by cavitation to RX High Temperature Low Cavitation Water Pump. There is also a new test question for the pump industry.
The cavitation or cavitation process of RX High Temperature Low Cavitation Water Pump is the process in which the flowing liquid generates bubbles and then bursts. When the absolute velocity of the fluid increases, due to the drop in the static pressure of the fluid, for some specific particles of the fluid at a certain temperature, although there is no heat input from the outside, they have reached the vaporization pressure, causing the particles to vaporize and produce bubbles. . Along the flow channel, if the static pressure of the fluid rises again and is greater than the vaporization pressure, the vapor bubble will burst quickly, resulting in a huge condensation shock that is inwardly explosive. If the rupture of the bubble does not occur when the liquid is flowing, but occurs at the wall surface of the flow guide component, cavitation will cause the wall material to be eroded.
When the RX High Temperature Low Cavitation Water Pump is operating under cavitation conditions, even if there is no erosion of the wall material, it will be found that the noise of the High Temperature Low Cavitation Water Pump at this time increases, the vibration increases, the efficiency decreases, and the head decreases. . So how to avoid cavitation?
1. Reduce the necessary cavitation margin of the RX High Temperature Low Cavitation Water Pump; when choosing a centrifugal pump, try to choose a pump with low cavitation margin.
2. Reduce the saturated vapor pressure of the liquid, such as lowering the liquid temperature;
3. Reduce pipeline losses, such as reducing valves, elbows, and pipeline length;
4. Adjust the installation height of the RX High Temperature Low Cavitation Water Pump. If it is suction, reduce the installation height; if it is reverse irrigation, increase the installation height.
