一、濾筒的檢查 定期檢查濾筒磨損情況，若磨損嚴重或發現有孔過濾效果明下降時立即更換。 1、一般檢查排放的過濾后的氣體是不是清晰 2、如果噴砂主機回砂困難，噴砂主機室視線不清晰，發現別的地方無問題，檢查濾筒是不是發生堵塞。 3、如果除塵系統配有壓差計的可監測濾筒的壓力降是否超出正常值 二、濾筒的拆卸 1.在拆換濾筒時，應先從機組的頂部檢修孔開始，這樣落入塵斗的塵粒將不致通過下面的檢修孔逸出。 2.用手反時針方向轉動旋鈕，松開螺栓，拆下密封蓋板，并置于一側。 3.用扳手反時針方向轉動旋下濾筒鎖緊螺母，置于一旁。 4.移動濾筒，剝掉濾筒和濾筒托板密封面之間的密封墊。慢慢轉動濾筒1/2轉，使所有堆積在濾筒頂部的垃圾掉落，從除塵器的前面檢修孔取出。（注意：拆換濾筒時需小心。當將濾筒從檢修口拉出時，沾滿灰塵的濾筒可能很重或會較難處理。） 5.檢查存灰地區的灰渣堆積情況，如果需要清掃即行清掃。 三、濾筒的安裝 1.將濾筒推入每個支架中，按順時針方向旋上并鎖緊鎖緊螺母。 2.擦凈檢修孔密封墊，按順時針方向轉動旋鈕，將密封蓋板重新安裝到支架的絲扣上，用手牢牢擰緊。 3.到這里除塵器便已安裝就緒，可供啟動。在啟動前再檢查電源，并接通壓縮空氣源。 濾筒拆裝和安裝時注意事項： 1拆卸有粉塵的濾筒時，需防護好自已的眼睛，防止粉塵進入眼睛。 2濾筒不可敲擊，也不可跌落地面或其它硬表面上，否則會損壞  濾筒，導致漏氣。 3為確保濾筒密封墊的可靠密封，必須將孔口四周濾筒支承襯板，每個濾筒端蓋和密封蓋板上的灰渣都清除干凈。 4不得使用溶劑來清潔密封墊的密封表面 四、灰渣的清除 1、每班需檢察集塵里上是否裝滿粉塵，并且及時進行清理。 2、在灰斗搬動和倒盡灰桶，重新安裝好灰筒。 五、除塵系統注意事項 1、仔細閱讀除塵系統說明書 2、除塵系統旁邊盡量預留1.5米之內的檢修位置。 3、除塵器如果放在廠房外部，一定要有防雨棚。

First, check regularly check cartridge cartridge wear, if badly worn or have holes that filter down effect that immediately replaced. 1, the general inspection of the filtered gas emissions is not clear 2, if the host back to the sand blasting difficult, sandblasting room hosts clear line of sight is not found elsewhere, no problem, check the cartridge is not jammed. 3, if the dust removal system equipped with a pressure meter can monitor whether the cartridge pressure drop beyond the normal two, the demolition of a cartridge in the cartridge when you replace them, should start at the top of the unit began to repair the hole, so fall dust particles into the dust bucket will not escape through the manhole below. 2 Turn the knob counter-clockwise by hand, loosen the bolt, remove the seal cover, and placed on one side. 3 with the wrench counter-clockwise rotation under the cartridge lock nut, set aside. 4 Move the cartridge, cartridge and cartridge stripped of pallets between the gasket sealing surface. Slowly turn the cartridge 1 / 2 turn so that all stacked in the cartridge at the top of the garbage falling from the dust in front of the manhole out. (Note: Removable caution when cartridge when the cartridge is pulled out from a manhole, covered with heavy dust or cartridge may be more difficult.) 5. Check the gray areas of the ash deposit buildup, If you need to sweep the line clean. Third, the cartridge installation 1 will push the cartridge into each bracket in a clockwise direction and tighten the lock nut on the screw. 2. Wipe manhole gasket, turn the knob clockwise, the sealing cover to re-install the bracket on threaded, tighten firmly by hand. 3. Precipitator here already installed ready for launch. Check the power before starting again, and connected to compressed air source. Cartridge disassembly and installation notes: 1 Remove the cartridge with dust, the need to better their own eye protection to prevent dust entering the eyes. 2 cartridge can not hit, can not be dropped on the ground or other hard surface, otherwise it will damage the cartridge, resulting in leakage. 3 To ensure reliable cartridge seal sealed cartridge bearing four weeks must be holes lining, end caps and closures for each cartridge are cleaned ash board. 4 Do not use solvents to clean the gasket sealing surface of the four, the removal of an ash, dust in the prosecution of class to be filled with dust on it, and promptly clean up. 2, moving in the hopper and down to make ash bucket, to re-install the gray cylinder. Fifth, note a dust removal system, dust removal system, carefully read the instructions 2, dust removal system next to the reserve as much as possible within 1.5 m of maintenance position. 3, the dust on the plant if the external, must have proof canopy.
