Small steps in the installation of rfq for water tube boiler parts: the main part of a small boiler for the body, chimney, sub-cylinder, water pumps, then its component mounting step is what is it? Here's to give you the specific introduction:
The party soon provide us with three hot water rfq for water tube boiler output foot, gas combustion, efficiency is very high, for us to save a lot of fuel costs. Moreover, these hot water boiler can be achieved by adjusting the full 24 hours a use hot water to meet the daily needs of old people. --customer feedback
First, preparatory work before the pressure test gas steam rfq for water tube boiler 1, internal cleaning and inspection of the surface of the test portion. 2, to check whether or pipe clogging. 3, installed by a qualified legal department check the pressure gauge (not less than 2), after a year to conduct a check by the legal department. 4, close the valves on the gas-fired, the safety cover can be used to seal the valve seat, into the water from the inlet pipe at a locus (water temperature of 20 ~ 70 ℃), and the vent valve was opened evacuated vent valve was closed after the water to be filled . Ambient temperature should be above 5 ℃, or measures must antifreeze; and to prevent surface condensation boilers. 5, the pump inlet pressure test stand can be connected after a pump pressure. Second, a water pressure test gas steam boiler, gas steam boiler test pressure is 1.65MPa. 2, the water pressure should rise slowly, when the pressure rose to the working pressure should be suspended boost, check for leaks or anomalies, and then rose to the test pressure, maintained at this pressure for 20 minutes, then again down to work check the pressure, the pressure should remain unchanged during the inspection. Third, gas steam boiler pressure test security measures and precautions 1, is strictly prohibited flange bolts tightened when the pressure exceeds 0.3MPa. 2, the hydraulic pressure test, the scene should be specially marked to prevent accidental danger. 3 can not stand directly in front of the valve flange and the test weld. Fourth, the gas steam boiler hydrostatic test acceptance criteria 1, and no water mist on the walls of the pressure receiving element and the weld metal. 2, after the pressure test found no residual deformation.
How the choice of steam rfq for water tube boilers should distinguish quality? Market top quality steam boilers are very different, so the user selects this product, it needs to identify its quality, then how to distinguish the quality of this product do? First a quality product from the main body of the boiler, it is necessary to identify the quality of the user through the body of the boiler. Body using what kind of material, and what kind of welding process, etc., the details of which are to be noted, that if the boiler has not reached a corresponding requirements in the above welding, when the fire will drain the user . If the material does not meet the corresponding requirements, it is difficult to meet the requirements of thermal insulation.
