what needs to be done in the maintenance of boilers in textile mills? recently, some customers have found our fast boilers, and what are the inspections for the maintenance of the textile mill boilers? in response to this problem, our technical staff gave an answer.
1, external inspection
in the process of using the boiler in the textile mill, the external state of the boiler should be checked regularly. it is necessary to ensure that there is no trace of corrosion and corrosion on the outer shell of the boiler, and the joint between the parts is not loose and loose, and the appearance of the boiler is not deformed. happening. in addition, it is necessary to check the weld seam of the boiler and the heat affected zone for defects such as cracks. if necessary, surface inspection or other flaw detection methods should be used for inspection.
2, internal inspection
there are many parts for the boilers in textile mills that need to be inspected internally. for those parts that have defects in previous inspections, the same inspection method or corresponding inspection method should be used to focus on the parts with defects or defects. inspection and verification; the heads, tube sheets, furnaces, and back-fire chambers and headers of low-nitrogen boilers are also subject to regular inspection; in addition, the combustion equipment of the boiler is inspected for burning and deformation.
3, water pressure check when testing the water pressure of a boiler in a textile mill, it is necessary to inspect the strength and tightness of the pressure-receiving parts of the boiler at the specified test pressure. when doing the water pressure check, pay attention to the connected parts that do not participate in the hydraulic test (such as inside and outside the boiler). pipelines, safety valves, etc.) should be taken with reliable isolation measures. if it is checked in a low temperature environment, then effective antifreeze measures should be taken. the above is some of the contents that should be tested regularly by the textile mill boiler. when inspecting the boilers of the textile mills, the inspection sequence is also very important. usually, internal inspection, hydraulic pressure inspection, and external inspection are performed first.
