KCB gear oil pump is a commonly used external gear pump in petroleum, chemical, food, resin, lubricating oil and other industries. The material of KCB gear oil pump produced by Sai ken Pump Industry can be selected from cast iron, cast steel, ductile iron and stainless steel according to the specific working conditions of users. , Duplex steel, etc.
Today, I will introduce the common causes of cavitation of KCB gear oil pumps:
1. The installation position is too high, the installation position of the KCB oil gear pump is too high, and the vacuum at the pump inlet increases, resulting in the pressure drop in the gear pump being too low.
2. The actual working conditions of the KCB gear oil pump deviate from the design conditions. When the KCB gear oil pump is operated under non-design conditions, the gear of the gear pump will produce a belt-shaped vortex belt from bottom to top. When the center pressure drops to saturation At the vapor pressure, the vortex zone becomes a cavitation zone and causes significant vibration of the pump set.
3. The inlet pipeline condition of the KCB gear oil pump is not good, the flow rate of the liquid in the flow channel is not uniform, or the pipeline is not tightly sealed, resulting in air inflow, and the saturated liquid cannot be sucked into the pump cavity of the gear pump. Unsaturated liquid is likely to form vapor eclipse.
4. The KCB gear oil pump is installed in a place with a high altitude. For example, the oil temperature delivered by the KCB gear pump is high. In a high altitude area, the atmospheric pressure is low, and the pressure at the suction port of the pump is correspondingly low; and the oil The higher the temperature, the higher the saturated steam pressure and the easier the oil vaporizes.
KCB type gear oil pump, 2CY gear pump, YCB arc gear pump, LYB vertical gear pump, LCB gear pump external gear pump can all pay attention to the above situation.
