求翻译：如果良浆管压力仍然很低，进浆管压力仍然很高，这说明堵塞尚未被排除。这时压力筛必须停止运行，打开上盖，吊出筛鼓，用高压水冲洗筛鼓，并检验筛鼓的磨损程度。是什么意思？

If it accepts pipe pressure remains low, slurry pipe pressure remained high, suggesting that blocking has not been ruled out. Pressure screen must stop running, open the cover on, hanging out Sieve drum, with high pressure water flushing Sieve drum, and the degree of wear test Sieve drum.
