Slurry selection, slurry pump, the pump Waugh (View)

Slurry flow in the slurry pump, when the slurry pump suction height is too large and liquid high temperature, resulting in the inlet pressure is less than or equal to the saturation vapor pressure of the liquid, due to the shape of the blades and the flow in which a sudden change in the direction of light the flow characteristics of the blades in the vicinity of non-face, etc. There are some local low pressure area. If the fluid pressure in the low pressure zone is reduced to the corresponding temperature of the saturated vapor pressure of the liquid, the liquid began to vaporize and produce bubbles; if the pressure continues to decrease, and the area will gradually increase the bubble and expand; Meanwhile pressure continues to decline, and the bubble area will gradually increase and expand; the same time part of the original may be dissolved in the liquid of some inert gas (such as oxygen, such as water), will reduce the pressure to escape back into bubbles. When these bubbles with the liquid flow into the pump high-pressure zone, which is condensed under pressure and quickly break even disappear. Parts of slurry pump wear and tear caused by many factors, including, slurry pump wear mechanism problem, the different parts of the wear mechanism is also different, mainly for the following three: 1, erosion in slurry pump During operation, the solid particles in the slurry with it to a certain speed overcurrent elements impact surface friction, resulting in over-current pieces too worn. Through analysis, erosion mechanism is cutting wear, abrasion and cutting deformation deformation wear plus three. 2, slurry pump cavitation wear during operation, overcurrent piece impeller inlet on the list this part of the region, for some reason, the absolute pressure of the liquid pumped down to the vapor pressure at that time temperature, the liquid begins to vaporize in the place produce steam slurry pump, the formation of bubbles, however, these bubbles with the forward movement of the liquid gradually, reaches a height of slurry pump models, the bubbles will dramatically reduce slurry pump Waugh cards, as well as storms off. Then the bubble starts to condense, the liquid particles at high speed filling voids, and have a strong impact on its metal surface. Thus, the metal surface under attack as well as spalling, resulting in material loss. 3, medium corrosion slurry pump delivered a certain pH Baoding horizontal slurry pump, pump flow and its parts will cause corrosion and wear phenomena, the joint effect of both, resulting in material loss.
