drawing of boiler room manufacturers
Based on this situation, our engineer suggested, to those frequent drawing of boiler room manufacturers turning on and turning down industry or factories, you would be better choose external circulation fluidized bed boiler to save money.
Our other fast drawing of boiler room manufacturers in the boiler industry strength already heard, through cooperation proves that our choice is correct. This water-tube boilers installed very quickly, basically no delay our production process, bring benefits to the enterprise. --customer feedback
Inspection 6 tons of steam drawing of boiler room manufacturers 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 water boiler, 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.
This type of horizontal drawing of boiler room manufacturers was used on virtually all steam locomotives in the horizontal "locomotive" form. This has a cylindrical barrel containing the fire tubes, but also has an extension at one end to house the "firebox". This firebox has an open base to provide a large grate area and often extends beyond the cylindrical barrel to form a rectangular or tapered enclosure. The horizontal fire-tube boiler is also typical of marine applications, using the Scotch boiler. Vertical boilers have also been built of the multiple fire-tube type, although these are comparatively rare; most vertical boilers were either flued, or with cross water-tubes.
