As The "heart" Of The Slurry Pump, The Maintenance Of The Impeller Is Particularly Important.

As the \"heart\" of the slurry pump, the impeller is an important part of the pump product, and its main function is to convert energy.When the motor drives the impeller to rotate, the blades in the impeller apply force to the fluid, forcing the fluid to rotate, thereby increasing the pressure potential and kinetic energy of the fluid.This process is the fundamental reason why the slurry pump can deliver liquid.When manufacturing impellers, the impeller can be a cast integral impeller or a fully welded integral impeller according to different application requirements.Due to its high strength and wear resistance, the welding impeller can better adapt to the impact and wear generated during the slurry pump transportation process.The overall impeller design also helps improve pump efficiency, reduce energy consumption and maintenance costs. Generally speaking, the hydraulic performance of the impeller is the decisive factor in the hydraulic performance of the pump. The main reason for pump failure is mainly caused by severe wear of the runner components, and the wear failure of the impeller is relatively common.It is very important for wear and failure analysis. Correct analysis is like finding the root cause of the problem. Therefore, failure analysis of impeller is very important.There are two main reasons for its failure: corrosion wear and abrasive wear.If the material is hit by small and loose moving particles, its surface will be damaged, which is corrosion wear.Generally, the particles should be less than 1mm and the impact speed should not exceed 55om/s.Once the particles exceed this range, it is easy to cause material damage.Abrasive wear refers to the damage to material caused by hard particles or hard concave convexity on the grinding surface during friction.It can be said that this form of slurry pump wear is relatively simple as it does not involve too much or even lubrication and adhesion issues.A failure of the impeller of the slurry pump will cause the equipment to be blocked and even stop running.Therefore, it is necessary to pay attention to the normal use and maintenance of the impeller and conduct corresponding inspections regularly to ensure the smooth operation of the impeller. Maintaining the slurry pump requires frequent inspection of the impeller condition, especially when there is a phenomenon of rapidity and slowness during use, the power should be cut off immediately and checked and maintained.It is also important to maintain proper clearance between the impeller and the guard plate or pump housing, as incorrect clearance can cause liquid leakage in the pump, affecting the performance of the impeller.
