设备磨损严重 ：由于仓泵采用高压力供气（0.4Mpa-0.6Mpa），弯头管道磨损严重，需要频繁更换，特别是出料阀、进料阀和排气阀磨损卡死，维修费用高，且维修环境恶劣。

　　Serious equipment wear: Due to the high-pressure gas supply (0.4Mpa-0.6Mpa) used by the warehouse pump, the elbow pipes are severely worn and require frequent replacement, especially the discharge valve, feed valve, and exhaust valve are worn and stuck, resulting in high maintenance costs and harsh maintenance environments.

　　操作复杂 ：仓泵采用料位及时间自动控制，控制台接线复杂，稍有故障就涉及电气、热工、除灰检修三大部门多个专业人员，延误检修时间，影响生产正常进行。

　　Complex operation: The warehouse pump adopts automatic control of material level and time, and the console wiring is complex. Even a slight malfunction involves multiple professionals from the electrical, thermal, and ash removal maintenance departments, delaying maintenance time and affecting normal production.

　　耗电量大 ：负压输送系统耗电量大，且由于磨损严重，设备使用寿命短，维护成本高。

　　High power consumption: The negative pressure conveying system consumes a large amount of electricity, and due to severe wear and tear, the equipment has a short service life and high maintenance costs.

　　环境极差 ：由于设备频繁抢修，到处漏灰，不仅危及厂内环境，也影响周围群众的生活环境，给文明生产造成极大影响。

　　Extremely poor environment: Due to frequent equipment repairs, dust leaks everywhere, not only endangering the factory environment, but also affecting the living environment of surrounding people, causing great impact on civilized production.

　　影响粉煤灰综合利用 ：由于输送系统损坏频繁，无法保证风选设备系统正常生产，影响粉煤灰的送出和利用，有损企业形象和利益。

　　Impact on comprehensive utilization of fly ash: Due to frequent damage to the conveying system, it is impossible to ensure the normal production of the air separation equipment system, which affects the delivery and utilization of fly ash and damages the image and interests of the enterprise.

　　管道参数不合理 ：在实际使用过程中，发现负压管道存在参数不合理、通道过小、转弯过多等问题，这些都会增加气体损耗，降低输送效率。

　　Unreasonable pipeline parameters: In actual use, it has been found that negative pressure pipelines have problems such as unreasonable parameters, too small channels, and too many turns, which will increase gas loss and reduce transportation efficiency.
