1. Slight/Single Blockage (Early Stages): Only minor parameter fluctuations occur: feed pressure is slightly higher than normal, pressure differential increases slightly, and proce

1. Depressurize before operation; pressurized operation is strictly prohibited. Before flushing, completely close the feed valve, empty all residual starch slurry from the hydrocyc

1. Upgrade feed pretreatment to prevent blockages at the source. This is the most crucial measure to prevent re-clogging: Fixed two-stage pre-treatment: Before entering the hydrocy

1. Slight/Single-tube blockage: This only causes a slight decrease in single-stage separation efficiency, manifested as a small reduction in starch recovery rate (generally 2%-5%)

1. Minor Blockage: High-Pressure Water Backflushing (Can be resolved in as little as 10 minutes) Suitable for minor blockage in a single hydrocyclone tube and slight pressure abnor

Step 1: Check the pressure difference (most intuitive): With the feed opening unchanged, if the feed pressure rises abnormally and the inlet/outlet pressure difference increases by

1. Replacement of Vulnerable Parts (Most Common Basic Repair Method) Applicable Scenarios: Suitable for cases where only the hydrocyclone tube is worn or aged, or where seals/gaske

1. Replacement of Aging Hydrocyclone Tubes Only (Most Common Minor Repair) This is a routine maintenance repair, taking only 1-3 days in total. It only requires disassembling the h

Preparation Before Repair 1. Determine Repair Dimensions: Refer to the new equipment drawings to determine the required dimensions of the hydrocyclone after repair. 2. Fabricate Co

1. Inadequate Material Selection Creates Potential for Aging: The main body is made of ordinary carbon steel instead of food-grade stainless steel: Carbon steel has poor corrosion

Production Performance Issues (Most Easily Observable) 1. Irreversible Decline in Separation Efficiency: Even with replacement of the hydrocyclone tubes and adjustment of process p

1. Select Qualified Anti-Aging Materials from the Source: Prioritize highly wear-resistant and corrosion-resistant materials during the selection phase to reduce the aging rate at
