Maintenance analysis of vertical pumps

The safe and reliable operation of slurry pumps is a prerequisite for fully utilizing equipment efficiency. The working principle and classification of slurry pumps, targeting the practical application of slurry pumps. Identify the issues that should be noted during the operation of the slurry pump. And analyze the causes and solutions of common faults in slurry pumps.
1, The submerged slurry pump is a type of pump that utilizes centrifugal force (the rotation of the pump impeller).
The machinery that increases the energy of solid-liquid mixed media is a key equipment in pipeline hydraulic transportation of solid particle media systems. Slurry pumps can be widely used in mining, power, metallurgy, coal, environmental protection and other industries to transport slurry containing abrasive solid particles. Such as slurry transportation in metallurgical beneficiation plants, hydraulic ash removal in thermal power plants, coal slurry and heavy medium transportation in coal washing plants, dredging of river channels, and river dredging. In the chemical industry, it is also possible to transport corrosive slurries containing crystals. The practical application of slurry pumps points out the sealing, selection, and design considerations for slurry pumps. And analyzed the common causes and solutions of faults during the operation of the slurry pump. In addition, maintenance and repair requirements are summarized based on the characteristics of the slurry pump. It has certain guiding significance for the actual operation of slurry pumps.
2, From a physical principle, slurry pump belongs to a type of centrifugal pump.
The conveying is a mixture of solid particles containing slag and water. The main working components of the slurry pump are the impeller and casing. The impeller device inside the casing is located on the shaft and connected to the prime mover to form a whole. When the prime mover drives the impeller to rotate, the blades in the impeller force the fluid to rotate. The blades do work on the fluid in its direction of motion, thereby forcing an increase in the pressure potential energy and kinetic energy of the fluid. Due to the wide application of slurry pumps, their types are diversified. But it can generally be divided into the following categories:
1. Slurry pumps are divided into single-stage slurry pumps and multi-stage slurry pumps based on the number of impellers.
2. Divided into horizontal slurry pump and vertical slurry pump from the position of pump shaft and horizontal plane.
3. The method of suction of water from the impeller is divided into single suction slurry pump and double suction slurry pump.
4. The structure of the pump casing is horizontally split and vertically combined.
