Slurry pump is an indispensable equipment in the production process such as beneficiation and coal preparation plant. The performance of the slurry pump is good or bad and it is of great significance to the beneficiation and preparation of the coal preparation plant. In general, the high-quality slurry pump adopts the international advanced theory of solid-liquid two-phase flow, and is designed according to the principle of minimum loss. The flow-through components are made of high-hard alloy cast iron, and their materials have high wear resistance, corrosion resistance, and resistance. The impact performance can improve the life of the slurry pump, and the geometric shape of the flow-through part conforms to the flow state of the medium, reducing the local and along-track hydraulic losses such as turbulence and impact, and reducing the wear of the flow-through parts of the slurry pump. Increased hydraulic efficiency and reduced operating noise and vibration are the best choice for beneficiation and coal plants. Even so, in the process of beneficiation or coal preparation plant, various failures cannot be avoided. Let's analyze how to troubleshoot the fault.
Troubleshooting Usually, the common faults of the slurry pump are the following:
A. The pump is not feeding or feeding is not good;
B. Seal water into the pump body;
C. stuffing box can not hold packing and leakage;
D. The pump cannot rotate;
E. Shake of the pump body or shaking of the motor mount, pump operation is not smooth;
F. oil seal leakage of the pump;
G. Abnormal sound in the volute of the pump.
