Inspection 6 tons of steam boiler pressure parts of introduction 1, the steam boiler Safety Supervision boiler if the following conditions to deal with various internal and external inspection and pressure parts overpressure test. (L) disassembly, after conversion and shifting means; (2) stops running and resume operation requires more than one year; (3) pressure-receiving element after major repairs; (4) according to the boiler operation, the state of the device must doubt when tested. 2, the boiler before the test is completed stopped, the elimination of the internal scale external boiler ash, soot, yet necessary to dismantle the furnace wall and the insulation cover, the following check Key: (l) when the drum welds, holes and the like are normal , for leakage; (2) presence or absence of corrosion of the boiler plate, where the groove from deformation and the like; (3) waterwall tubes are not bent, deformation, etching, etc. inflated; (4) a pyrotechnic tubes are not bent, the tube plate out and gusset weld cracks; (5) to the water pipes, sewage pipes and the welding drum presence of a defect. 3, severe corrosion do accounting should be done before the super strength test. 4, before the hydrostatic test should do the following tasks (l) portion of the test, the internal management and Pu inspection surface; (2) to check the clogging of pipes; gauge (3) is mounted in the modified inspection (no less to 2); (4) change means drains and purge valve. 5, in a hydrostatic test shall meet the following requirements: (l) hydrostatic test shall be carried out when the ambient temperature is higher than 5 ℃, measures should be adopted or against the cold. (2) filled with commercial 18 ton water boiler dealer, if the metal surface condensation, should be removed, a preliminary check for leaks and then slowly open the booster, when raised to 3kg / CM, a check should be carried out, can be tightened if necessary manholes , hand holes and flange bolts; (3) when the water pressure up to operating pressure, the opening pressure should be temporarily stopped to check for any leakage of each portion, and then increased to the test pressure for 5 minutes and then back down to the operating pressure checks, meet the following requirements is eligible. ① In the test pressure was raised, the pump stops, the pressure drop must not; no leakage in the outer weld ②; ③ watermark (traces of water) may or tears (not downflow drops) not being replenished weld; ④ Water after the pressure test, visual observation found no residual deformation.
Second, the maintenance and repair of condensing boilers. On some level, maintenance and repair condensing boiler can directly determine the useful life of stability and performance of the device. Condensing boiler shut down at any time, there are stringent performance standards, after a period of time before stopping power, but also for regular abnormal exclude dirt between the comprehensive clean-up and the line, once the line is damaged or loose parts should be timely make protective measures in accordance with the instructions in order to avoid late cause more accidents.
Beiqi Panther car 6 tons of steam condensing one fuel gas steam boiler project has been successfully completed. This series boiler adopt advanced design concepts, using the waste heat of flue gas cascade, with the use of the condenser and the economizer fully absorb the waste heat in the flue gas, the boiler efficiency has been greatly improved.
Although now this equipment, mainly to provide the steam needed, but the choice is very diverse, as long as it is understood that during the time, it can be found, such as a steam boiler plant, is in the energy With some changes on the way, such as natural gas and the like, there is electrical energy, etc., are now leading to the boiler equipment, energy began to appear a lot of ways, allowing plants to be selected now. And this boiler equipment, began to have automated operations and control, so that the same people have more choices.Free Chat
