The Difference Between Mud Pumps And Slurry Pumps

图片
Mud pump and slurry pump are both a kind of impurity pump. What are the differences between these two pumps that make it difficult for users to choose?   1. The difference in working principles The working principle of the mud pump is that the motor drives the piston through the link mechanism, which causes the change of the enclosed volume in the mud pump, and forms the change of the pressure difference between the inside and outside of the pump, thereby completing the water absorption and drainage process; while the working principle of the wear-resisting slurry pump is that the motor drives the impeller to rotate, that is, the impeller works on the slurry to increase the kinetic energy of the slurry.   2. The difference in the pumped medium Mud pump, as the earliest pump type, is generally made of cast iron. Its wear resistance is low. As an important part of drilling machinery, it can only be used to transport mud or slurry that contains suspended particles.  Slurry pumps  are main

What are the factors affecting the quality of gray cast iron castings?

  Grey cast iron  is a type of iron that is characterized by its grey color and graphite flakes, which are dispersed throughout the material. It is a relatively inexpensive and readily available material that is widely used in the casting industry for a variety of applications. Grey cast iron is produced by melting pig iron, which is a raw form of iron, along with scrap steel and other alloying elements in a furnace. The molten metal is then poured into a mold, where it solidifies and takes the shape of the mold. This process is known as  casting grey iron ​ is called grey because of the color of the surface of the casting after it has cooled.     There Are Several Factors That Can Affect the Quality of a  Grey Cast Iron Casting . These Include: Raw Materials The quality of the raw materials used in the casting process is critical to the quality of the finished casting. It is important to use high-quality pig iron and other alloying elements to ensure that the finished casting has the
