High temperature submerged pump should have at least a rigid bearing. The bear axial force can limit axial channeling move and radial deflection. The lubrication usually select the grease lubrication and it can fill the grease through oil cup.
    Sliding bearing lubrication of high temperature liquid pump generally have two ways: 1. Self lubrication uses the cleaning medium that it is transported as a lubricant. It can be used for cooling and lubrication of sliding bearing. 2. External lubrication usually uses tap water or clean oil as a lubricant. The flow of lubricating fluid is usually 0. 3 ~ 0. 6 m³ / h, the pressure is 0. 2～0. 4 MP.
