Inventory single-stage slurry pump model performance parameters, single-stage slurry pump working principle

As a member of the large family of slurry pumps, the single-stage slurry pump, with its simpler structure, operation and maintenance requirements, is more widely used and saves a lot of resources. Today, Xiao Bian to inventory a single-stage slurry pump performance parameters and its working principle. Inventory of single-stage slurry pump model performance parameters, single-stage slurry pump working principle (a) single-stage slurry pump model performance parameters speed: motor direct drive 2900/1480/980/730/590 r / min pulley Indirect transmission in line with customer requirements Medium temperature: Generally ≤ 80 ℃ Special up to 110 ℃ Solid mixture weight concentration: mortar concentration ≤ 45% pulp concentration ≤ 60% Flow range: 30-2000m3 / h Head range: 15-130m The working principle of the slurry pump First of all, tell about the relationship between the centrifugal pump and slurry pump, and then the principle of slurry pump will naturally clear. Centrifugal concept is from the original pump. There are many types of pumps, depending on the angle can be divided into dozens of categories. Centrifugal pump is divided from the working principle of the pump, through the centrifugal force to achieve the process of supercharging the transmission medium. There are also other common types including screw principle, plunger principle can be divided into different centrifugal principle of the pump. Finish the concept of centrifugal pump, say the slurry pump, slurry pump is divided from another point of the pump, that is divided from the transmission medium. As the name implies, the slurry pump delivers a mixture of solid particles containing water and water. However, in principle, the slurry pump is a centrifugal pump. So these two concepts make it clear. Centrifugal pumps are the main components of the impeller and the casing, the casing of the impeller device is located on the shaft, and connected with the prime mover to form a whole. When the prime mover drives the impeller to rotate, the blades in the impellers force the fluid to rotate, ie the blades work on the fluid along its direction of motion, forcing the pressure potential energy and kinetic energy of the fluid to increase. At the same time, the fluid flows under the force of inertia from the center to the edge of the impeller and flows out of the impeller at a very high speed into the pressure chamber, which is then discharged through the diffuser tube. This process is called as pressure watering. At the same time, due to the flow of fluid in the center of the impeller to the edge, a low-pressure zone is formed in the center of the impeller. When it has a sufficient vacuum, the fluid enters the impeller through the suction chamber under the pressure of the suction end (generally, atmospheric pressure) Water absorption process. Due to continuous rotation of the impeller, the fluid is continuously discharged and sucked in to form a continuous operation. Centrifugal pumps (including the slurry pump) work process, in fact, is a process of energy transfer and conversion. It transfers the mechanical energy of a motor rotating at high speed through the blades of the pump and translates into the pressure and kinetic energy of the fluid being pumped.
