Slurry pumps are commonly used in industry to transport materials. They are widely used power machinery equipment in metal processing plants, chemical plants, power plants, sand processing industries, ceramics and glass factories. The normal operation of the pump plays a very important role.
Generally, the slurry pump is used to transport various abrasive and corrosive materials. The materials contain solid particles of a certain size and some acid and alkali ions. Cavitation, corrosion and other damage, among which the slurry pump pressure relief cover is the central part of the slurry pump, which will suffer from serious abrasion, corrosion, cavitation and other problems.
1. Wear: The relative movement speed between the solid ions in the slurry and the pressure relief cover of the slurry pump is large, and the solid particles cause continuous impact and wear on the surface of the flow passage parts, and the surface of the pressure relief cover is torn and material loss occurs. , and eventually the pressure relief cover is damaged;
2. Corrosion, the material conveyed by the slurry pump contains certain acid, alkali and salt ions, and the surface of the pressure relief cover is corroded by chemical reaction and electrochemical reaction during the conveying process of the material;
3. Cavitation, due to the uneven air pressure inside the slurry pump, a large amount of liquid gasification produces a large number of air bubbles in the place where the air pressure is small, and the air bubbles burst in the place where the air pressure is high, and the pressure relief cover produces a violent impact when the liquid fills the gap. to damage it;
Among them, Lianhe Shengxin is a manufacturer dedicated to the manufacture of mining machinery and equipment for many years. The wear resistance of its alloys can reach 128%, and it has been successfully applied to the pressure relief cover of the slurry pump, which makes the overall wear resistance and corrosion resistance of the slurry pump. promote.
