常見故障及處理

　　Common faults and their solutions

　　倉泵常見故障一般在流化加壓階段，倉泵內(nèi)壓力上升緩慢達不到輸灰要求主要原因有以下幾個：

　　The common faults of the bin pump usually occur during the fluidization and pressurization stage. The main reasons for the slow increase in pressure inside the bin pump and the inability to meet the ash conveying requirements are as follows:

　　1. 儲氣罐壓縮空氣壓力低或進氣閥開不到位。

　　1. The compressed air pressure in the storage tank is low or the intake valve cannot be opened properly.

　　2. 進料閥漏氣。

　　2. The feed valve is leaking air.

　　a.進料閥沒有關(guān)到位，解決辦法：調(diào)整氣缸行程位置使進料閥閥蓋關(guān)閉嚴密。

　　a. The feeding valve is not closed properly. Solution: Adjust the cylinder stroke position to make the feeding valve cover tightly closed.

　　b.進料閥閥座或閥蓋上下密封圈吹損 解決方法：需把整個進料閥總成拆下，拆下上下密封圈，檢查閥座與閥蓋是否有吹損，如有需補焊車加工后換裝新的密封圈。

　　b. Solution for blowing damage to the upper and lower sealing rings of the feed valve seat or valve cover: The entire feed valve assembly needs to be removed, the upper and lower sealing rings need to be removed, and the valve seat and valve cover need to be checked for blowing damage. If there is any damage, it needs to be repaired by welding and machining, and a new sealing ring needs to be installed.

　　3. 出料閥漏氣。

　　3. The discharge valve is leaking air.

　　a.出料閥關(guān)不到位。解決辦法：通知熱工檢查電磁閥及氣管路。

　　a. The discharge valve cannot be closed properly. Solution: Notify the thermal engineer to inspect the solenoid valve and gas pipeline.

　　b.出料閥密封組件吹損需更換出料閥

　　b. The sealing component of the discharge valve is blown and needs to be replaced

　　4. 倉泵硫化布堵。

　　4. The warehouse pump is blocked with vulcanized cloth.

　　a.飛灰量多，粘性大，飛灰潮濕，這種情況一般發(fā)生在電除塵檢修過后，由于水沖洗電除塵或長時間不投用引起。

　　a. The amount of fly ash is large, the viscosity is high, and the fly ash is humid. This situation usually occurs after the maintenance of the electrostatic precipitator, due to water washing of the electrostatic precipitator or prolonged disuse.

　　b.壓縮空氣水分過多引起硫化布堵塞。需檢查空壓機出氣后凈化裝置是否正常及儲氣罐疏水情況。確保壓縮空氣干燥。

　　b. Excessive moisture in compressed air can cause blockage of vulcanized fabric. It is necessary to check whether the purification device after the air compressor exhausts is normal and the drainage condition of the air storage tank. Ensure that the compressed air is dry.
